WARNING—PROTECTIVE EARTH
Protective Earth (PE) must be connected to the termination point on the back side of
the unit next to the label with the symbol (or 1 of 3 other like termination
points without label) to reduce the risk of electric shock. This connection will be
made using a thread-forming screw. The conductor providing the connection must
have a properly sized ring lug and wire larger than or equal to 4 mm² (12 AWG).

The calibration and checkout procedure should only be performed by authorized

personnel knowledgeable of the risks posed by live electrical equipment.

The installation must include the following:

• The power supply mains should be properly fused according to the installation
instructions and the appropriate wiring requirements.
• A switch or circuit breaker must be included in the building installation in close
proximity to the equipment and within easy reach of the operator, and must be
clearly marked as the disconnecting device for the equipment. The switch or
circuit breaker will only remove power to the unit—hazardous voltages may still
be connected to other terminals on the unit.

Electrostatic Discharge Awareness

All electronic equipment is static-sensitive, some components more than others.
To protect these components from static damage, you must take special
precautions to minimize or eliminate electrostatic discharges.

Follow these precautions when working with or near the control.

1. Before doing maintenance on the electronic control, discharge the static

electricity on your body to ground by touching and holding a grounded metal
object (pipes, cabinets, equipment, etc.).

2. Avoid the build-up of static electricity on your body by not wearing clothing
made of synthetic materials. Wear cotton or cotton-blend materials as much
as possible because these do not store static electric charges as much as
synthetics.

3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam

cups, cup holders, cigarette packages, cellophane wrappers, vinyl books or
folders, plastic bottles, and plastic ash trays) away from the control, the
modules, and the work area as much as possible.

4. Do not remove the printed circuit board (PCB) from the control cabinet
unless absolutely necessary. If you must remove the PCB from the control
cabinet, follow these precautions:

• Do not touch any part of the PCB except the edges.

• Do not touch the electrical conductors, the connectors, or the

components with conductive devices or with your hands.

• When replacing a PCB, keep the new PCB in the plastic antistatic
protective bag it comes in until you are ready to install it. Immediately
after removing the old PCB from the control cabinet, place it in the
antistatic protective bag.

CAUTION—ELECTROSTATIC DISCHARGE
To prevent damage to electronic components caused by improper handling,
read and observe the precautions in Woodward manual 82715, Guide for
Handling and Protection of Electronic Controls, Printed Circuit Boards, and
Modules.

Installation

This chapter provides the general information for mounting location selection,
installation, and wiring of the EGCP-3 control. Hardware dimensions for
mounting, and electrical ratings, and requirements are given for wiring the
EGCP-3 in a specific application.

Unpacking the Shipping Carton

Before unpacking the control, refer to the inside front cover and page iv of this
manual for WARNINGS and CAUTIONS. Be careful when unpacking the control.
Check for signs of damage such as bent or dented panels, scratches, and loose
or broken parts. If any damage is found, immediately notify the shipper.

The EGCP-3 was shipped from the factory in an anti-static foam-lined carton.
This carton should always be used for transport of the EGCP-3 when it is not
installed. Read page iii, Electrostatic Discharge Awareness, before handling the
EGCP-3 Control.

Check for and remove all manuals, connectors, mounting screws, and other
items before discarding the shipping box.

General Installation Notes and Warnings

When selecting a location for mounting the EGCP-3 control, consider the
following:
• Protect the unit from direct exposure to water or to a condensation-prone
environment.
• The operating range of the EGCP-3 control is –20 to +70 °C (–4 to +158 °F).
• Provide adequate ventilation for cooling. Shield the unit from radiant heat
sources.
• Do not install near high-voltage or high-current devices.
• Allow adequate space around the unit for servicing.
• Do not install where objects can be dropped on the terminals.
• Ground the chassis for proper safety and shielding.
• When installing on a generator set package, provide vibration isolation.

Mounting
The EGCP-3 is an integrated control package. All control hardware is contained
in one compact enclosure. All field wiring connects to the EGCP-3 through
terminal blocks located on the top and bottom surfaces. Placement of the EGCP-
3 must allow sufficient room for wiring access. The EGCP-3 weighs
approximately 4.3 kg (9.5 pounds).

To mount the EGCP-3 panel, use type M5 x 12 mm thread-forming screws. The

EGCP-3 is factory shipped with mounting screws included in the box. Eight
screws are required for secure mounting (Woodward part number 1029-529).
The screws are inserted from behind the panel, through a hole in the panel, and
into the cast aluminum flange of the EGCP-3. The 12 mm screw length assumes
a panel thickness of 1.2—4.2 mm (0.047—0.164 inches).

6 Woodward
 Manual 26122 EGCP-3 Installation
The EGCP-3 is shipped with mating connectors for all terminals. However, for
service and convenience, Woodward also carries an EGCP-3 connector kit (P/N
8928-178) that contains all of the mating terminal blocks used on the EGCP-3.
See Appendix A for mating connector information.

The EGCP-3 must be mounted in an appropriate enclosure for the installed

environment. This equipment is designed for installation within a control room
panel or cabinet or in a vibration damped enclosure on a generator package. The
EGCP-3 is equipped with a sealing gasket behind the front flange. When properly
installed within a NEMA 4X panel or cabinet, the seal and front panel of the
EGCP-3 will meet NEMA 4X ratings.

NOTE
When mounting into an enclosure, make sure the enclosure is vented to
atmosphere through a Type 4 vent tube or unsealed conduit.

Figure 1-1 shows a physical outline drawing with dimensions of the EGCP-3 for
reference during the construction of mounting panels, etc. The enclosure size is
282 mm high x 358 mm wide x 134 mm deep (11.1 inches H x 14.1 inches W x
5.3 inches D).

Figure 2-1 is a panel cutout template that may be used to locate and size the
cutout and through holes to be made when installing the EGCP-3.

Environmental Specifications
Please refer to Technical Specifications in Appendix C and inside the back cover
of this manual for environmental characteristics. When installed on a generator
package, the EGCP-3 should be mounted in a suitable enclosure where the
entire enclosure is isolated from engine and generator vibrations above 30 Hz.

Electrical Connections
Most inputs and outputs to the EGCP-3 are made through “CageClamp” terminal
blocks.

For noise suppression, it is recommend that all low-current wires be separated

from all high-current wire.

See Appendix A for additional information on connector wiring.

Most of the EGCP-3 control’s terminal blocks are designed for removal by hand.
After EGCP-3 input power is disconnected, the pluggable terminal blocks can be
removed one at a time by pulling them straight out. Be careful not to pull the plug
out at an angle, as this will fracture the end terminal.

Each Terminal block has a label (PS, PSEN, SCOR) to indicate which board it is
used with, and terminal numbering to indicate which terminal block on that board
to plug into. The board assemblies also are marked with a label to match with
terminal block labels.

The pluggable terminal blocks are screwless CageClamp-style blocks. The

spring clamp can be opened with a standard 2.5 mm (3/32 inch) flat bladed
screwdriver (see Figure 2-2). The EGCP-3 pluggable terminal blocks accept wire
28 to 18 AWG (0.08 to 0.8 mm²). One 18 AWG (0.8 mm²) wire, or two 20 AWG
(0.5 mm²) wires, or three 22 AWG (0.3 mm²) wires can be easily installed in each
terminal. Wires for the pluggable I/O terminals should be stripped 8 mm (0.3
inch).

Free Hand (holds spring open) Bench (opens spring
while force is applied)

Figure 2-2. Wiring of Pluggable Spring Clamp Terminals

8 Woodward
Manual 26122 EGCP-3 Installation
The EGCP-3 fixed terminal blocks used for the power supply input accept wires
from 28 to 18 AWG (0.08 to 0.8 mm²). One 18 AWG (0.8 mm²) wire, or two 20
AWG (0.5 mm²) wires, or three 22 AWG (0.3 mm²) wires can be easily installed
in each terminal. Wires for the fixed mounted power terminals should be stripped
5 mm (0.2 inch).

Figure 2-3. Wiring of Fixed Terminal

NOTE
Do not tin (solder) the wires that terminate at the EGCP-3 terminal blocks.
The spring-loaded CageClamp terminal blocks are designed to flatten
stranded wire, and if those strands are tinned together, the connection loses
surface area and is degraded.

All ac wiring for voltages and currents is done with fixed screw barrier blocks
rather than pluggable terminal blocks. The fixed screw barrier blocks accept
wires terminated into terminal lugs for #6 screws.

Protective Earth (PE) must be connected to the termination point on the backside

of the unit next to the label with the symbol (or 1 of 3 other like
termination points without label) to reduce the risk of electric shock. This
connection will be made using a thread-forming screw (M4 x 6 mm). The
conductor providing the connection must have a properly sized ring lug and wire
larger than or equal to 3.3 mm² (12 AWG).

Recommended Grounding Practices

Providing the proper ground for the EGCP-3 is important. Improper connection of
the EGCP-3 chassis to the ground plane may lead to stray currents between the
reference point for the ac signal sources (current and voltage transformers), and
the reference point for the sensing inputs on the EGCP-3. Differences in potential
between these two points results in equalizing current flow which then produces
unacceptably high common mode voltages. Common mode voltages may result
in improper readings for the sensed ac inputs, or even damage to the EGCP-3 in
extreme cases. To minimize this problem, it is necessary to provide a low
resistance path between the ac signal reference point, and the chassis of the
EGCP-3. Typically this point is the designated ground for the generator set and
related instrument transformers.

Shields and Grounding

An individual shield termination is provided at the terminal block for each of the
signals requiring shielding. These include all sensor wiring and ac signal inputs.
Relay outputs, contact inputs, ac power inputs, and power supply wiring does not
normally require shielding, but can be shielded if desired. All shielded cable must
be a twisted conductor pair. Do not attempt to tin (solder) the braided shield. All
signal lines should be shielded to prevent picking up stray signals from adjacent
equipment. Wire exposed beyond the shield should be as short as possible, not
exceeding 50 mm (2 inches). The other end of the shields must be left open and
insulated from any other conductor.

The EGCP-3 is designed for shield termination to earth ground at the EGCP-3. If
intervening terminal blocks are used in routing a signal, the shield should be
continued through the terminal block. If shield grounding is desired at the
terminal block, it should be ac coupled to earth. All other shield terminations
except at the EGCP-3 should be ac coupled to earth through a capacitor. A 1000
pF, 500 V capacitor is sufficient. The intent is to provide a low impedance path to
earth for the shield at frequencies of 150 kHz and up. Multiple direct connections
of a shield to earth risk high levels of current to flow within the shield. See
Woodward application note 50532, Interference Control in Electronic Governing
Systems, for more information.

Where shielded cable is required, cut the cable to the desired length and prepare
the cable as instructed below.
1. Strip outer insulation from both ends, exposing the braided or spiral wrapped
shield. Do not cut the shield.
2. Using a sharp, pointed tool, carefully spread the strands of the shield.
3. Pull inner conductor(s) out of the shield. If the shield is the braided type, twist
it to prevent fraying.
4. Remove 6 mm (1/4 inch) of insulation from the inner conductors.
5. Connect wiring and shield as shown in plant wiring diagram.

For noise suppression reasons, it is recommend that all low-current wires be

separated from all high-current wires. Input power ground terminal should also be
wired to earth ground. Installations with severe electromagnetic interference
(EMI) may require additional shielding precautions, such as wire run in conduit or
double shielding. Contact Woodward for more information.

Shields can be grounded at both ends (EGCP-3 and load) if the cable length is
sufficiently short (within a cabinet) to prevent ground loop current in the shield.

Cabinet Installations: If the EGCP-3 is installed in a cabinet, shielded I/O can be

terminated directly to the cabinet (earth ground) at the entry to the cabinet, as
well as at the EGCP-3.

Isolation
Figure 2-6 shows how the I/O is isolated with regard the main system power
supply and other I/O types. Each input wiring diagram also shows how an input
type is isolated in more detail.

Figure 2-6 uses numerals to indicate isolation grouping. Power and Ground
isolation groups are indicated with a P# and G#. Every instance of the same P#
and G# indicates that the item is part of the same group and not isolated from the
other members of the same group. For example, all analog inputs, analog
outputs, and CPUs use P9 for power and G9 for ground.

Input Power
The EGCP-3 control requires a nominal voltage source of 18 to 32 Vdc, 22 W.
Power to the control should be maintained whenever the generator set is
available for service. The control will remain active when connected to engine
cranking batteries during cranking.

CAUTION—START-UP
Power must be applied to the EGCP-3 control at least 60 seconds prior to
expected use. The control must have time to do its power up diagnostics to
become operational. Failure of the diagnostics will disable control function.

WARNING—POWER SUPPLY CONNECTIONS

The EGCP-3 power supply board must have the input power removed before
installing or removing any connectors or wiring.
This equipment is suitable for use in Class 1, Division 2, Groups A, B, C, and
D, or non-hazardous locations only.
The EGCP-3 is suitable for use in European Zone 2, Group IIC environments
per DEMKO certification.
Wiring must be in accordance with Class I, Division 2 wiring methods and in
accordance with the authority having jurisdiction.
Do not connect more than one main power supply to any one fuse or circuit
breaker.

The input to the Power supply must be of a low impedance type for proper
operation of the control. DO NOT power a control from a high voltage source
containing dropping resistors and zener diodes. If batteries are used for
operating power, an alternator or other battery-charging device is necessary to
maintain a stable supply voltage.

Input Power Ratings

Voltage Range 18–32 Vdc
Maximum Voltage 40 Vdc
Minimum Voltage 9 Vdc (engine cranking only)
Input Current 0.9 A @ 24 Vdc
1.1 A @ 18 Vdc
Maximum Input Power 22 W
Typical Input Power 20 W @ 24 Vdc
Interrupt Time Holdup 8 ms @ >= 24 Vdc input voltage
Efficiency 70% minimum over operating input voltage range
Reverse Polarity Protection 100 Vdc
Input Wiring Constraints The EGCP-3 must be wired such that no other device receives
power from the wiring between the EGCP-3 and the power supply
source.
Input Wire Size 12 AWG (2.5 mm²)
Input Fuse Rating 3 A (time delay with melting I2t 100A2 sec)

Significant inrush currents are possible when current is applied to the EGCP-3
control. The magnitude of the inrush current depends on the power source
impedance, so Woodward cannot specify the maximum inrush current. Time-
delay fuses or circuit breakers must be used to avoid nuisance trips.

Resolution in volts 0.15 Vdc
Maximum error due to temperature change 1.0 Vdc
Maximum error due to load change 1.0 Vdc
Total maximum error at 25 °C 1.2 Vdc

Input Power Wiring

Protective earth ground (PE) must be connected to the chassis at th

labeled termination point on the back of the display. See Figure 3-6 The power
supply grounding terminals should also be connected to earth to ensure
grounding of the power supply printed circuit boards. The grounding conductor
must be the same size as the main supply conductors or the PT wires, whichever
is larger.

Note that the control’s power supplies are not equipped with input power
switches. For this reason, some means of disconnecting input power to each
main power supply must be provided for installation and servicing.

It is expected that the installation of this equipment will include overcurrent

protection between the power source and the EGCP-3. This overcurrent
protection may be accomplished by series connection of properly rated fuses or
circuit breakers. Branch circuit protection of no more than 250% of the maximum
EGCP-3 power supply input current rating must be provided. Maximum fuse
rating must meet the 250% UL listing requirements. The use of properly sized UL
class CC, J, T, G, RK1, or RK5 fuses meet the requirements for branch circuit
protection. Do not connect more than one EGCP-3 to any one fuse. Use only the
wire size specified 1above, or equivalent, that meets local code requirements.
Time delay fuses should be used to prevent nuisance trips.

The power supply holdup time specification is the time the supply will continue to
operate within specification after its input power is interrupted. This information
may be useful in specifying uninterruptible power supply (UPS) systems.

NOTE
2.5 mm² (12 AWG) is the largest wire gauge size that can be connected to the
control power input terminal blocks.

The minimum continuous input voltage allowed is 18 V at the power input of

the control. The length, size of wire, and load current will determine the
minimum supply output voltage. The minimum supply voltage measured at
the source should always be greater than 18 V. Example: two (source and
return) 20 foot (6 m) lengths of 14 AWG (2.5 mm²) wire carrying 1.2 A
(maximum rated current) will result in a voltage drop from source output to
control power input of approx. 0.16 volts. The resulting supply voltage from
the example must be greater than 18.16 volts.

The EGCP-3 will remain in operation when an electrical starter is engaged, if

input power drops to no less than 9.0 V.

The power supply and ground connections are located on the top of the EGCP-3
on the power supply board. The power supply board is the board on the top of
the stack (furthest away from the display area).

Potential Transformer (PT) Inputs

The Generator and Mains ac voltage inputs can accept voltages up to 300 Vac
RMS maximum between the positive and negative terminals of each input. The
inputs may be connected line-to-line or line-to-neutral. For example, if the inputs
are connected line-to-neutral, each input A-N, B-N, and C-N may have up to 300
Vac. Therefore, a 480 Vac generator may be wired to the EGCP-3 using line-to-
neutral connections resulting in 277 Vac at the inputs.

Input Voltage Range Selections 70, 120, 240 Vac RMS

Max. Input Voltage 300 Vac
Input Current 3 mA maximum
Input Frequency 40–70 Hz
Common Mode Rejection Voltage ±450 Vdc minimum
Common Mode Rejection Ratio -63 dB minimum

The EGCP-3 must be configured for a voltage range relative to the input
(Potential Transformer secondary) provided. For example, if a phase (+) to phase
(–) input to the EGCP-3 is to be a nominal of 70 Vac, set the range to the 70 volt
range. No change in wiring is necessary. This configuration setting maximizes
the accuracy for the voltage level being sensed. There is also a voltage floor
below which a voltage cannot be detected so setting the correct range is
important for more than just accuracy. See the table below for the voltage floor at
each range.

d Range Dead bus Voltage Detected Maximum Voltage Detected

70 27 Vac 100 Vac
120 40 Vac 150 Vac
240 80 Vac 300 Vac

If potential transformers are used, be careful to select an accurate transformer.

The largest source of inaccuracy in the system will be the transformer, since
even the most accurate transformer is less accurate than the ac voltage inputs to
the EGCP-3. The calibration menu contains turns ratio compensation factors for
each PT input. Follow the calibration procedure to negate much of the
transformer error.

The Bus PT inputs are required for the synchronization function. At least a single
phase connection must be made if the EGCP-3 is intended for synchronizing.

When the PT input to the control is conditioned with a transformer the generator
and mains transformer ratio is entered into the EGCP-3. This is described in the
Configuration section of the Operation Manual. The EGCP-3 will use the PT ratio
and the entered configured Range to calculate the actual system voltage(s).

Woodward 21
EGCP-3 Installation Manual 26122
EXAMPLE:
Hwd range = 120
PT ratio = 4
Measured PT secondary (input at terminals) = 112.5 Vac
The EGC-3 will display 450 Vac for this input voltage.

Hazardous Live
The following circuits are classified as Hazardous Live because they carry
potential shock hazardous voltages during normal operation or under single fault
conditions:
• Potential transformer (PT) inputs
• Current transformer (CT) inputs
• Voltage bias outputs

WARNING—HIGH VOLTAGE/CURRENT
Do not touch or make contact with the above inputs and outputs during
system operation when such circuits are live. Possible serious personal
injury or death could result.

These inputs and outputs are provided with 500 V of dielectric isolation from
chassis ground. In addition, these inputs/outputs are isolated from safety extra-
low voltage (SELV) circuits (such as serial communication, PC/104 circuits) by
optoisolators or transformers provided with double insulation and 3 000 Vac of
dielectric isolation.

PT—3∅ Wye, L-N, No Transformers

No transformers are necessary if the voltage input to the EGCP-3 is less than
300 Vac at a given phase input. This diagram shows a system where both the
generator and bus are less than 300 Vac measured line-to-neutral. Each is
connected to the EGCP-3 in a L-N mode without transformers (PT Ratio = 1:1). It
is not required that both the mains and the generator inputs be connected in the
same manner. One could be L-L and the other L-N if preferred. Also, one could
use transformers and the other not. The diagram shown is simply an example of
a typical system.

Current Transformer (CT) Inputs

The Generator and Mains ac current inputs can accept currents up to 7 A ac
RMS maximum between the positive and negative terminals of each input. The
CT inputs are rated at 5 A ac RMS nominal and function down to 50 mA. For
optimum accuracy in the usable range, it is recommended to use 5 A secondary
CTs (Do not use 1 A secondary CTs).

Input Current 5 A RMS full scale

Max. Transient Input Current (continuous) 7.07 Aac-rms
Max. Transient Input Current (1 sec.) 50 Aac-rms *
Input Burden 0.15 VA
Input Frequency 40–70 Hz
Common Mode Voltage ±250 Vdc minimum
Common Mode Rejection Ratio –63 dB minimum
*—EGCP-3 versions 8406-113 Rev E and 8406-114 Rev D or later

Be careful to select an accurate current transformer. The largest source of

inaccuracy in the system will be the transformer since even the most accurate
transformer is less accurate than the AC current inputs to the EGCP-3. The
calibration menu contains turns ratio compensation factors for each CT input.
Follow the calibration procedure to negate much of the transformer linear error.

The EGCP-3 does not require three phases for current calculations. The user
can configure the EGCP-3 for single phase, and all functionality will be modified
accordingly. The phase input that must be provided is the A phase.

The Bus CT inputs are not required for operation. The Bus CT inputs are used for
alarm functions only and are not used for any control functions.

The generator and mains Current Transformer ratio is entered into the EGCP-3.
This is described in the Configuration section of the Operators Manual (26137).
The EGCP-3 will use the CT ratio to calculate the actual system current(s).

EXAMPLE:

Single Phase Monitoring

In a single phase monitoring system, the EGCP-3 will only use the A phase CT
input. Anything connected to the B and C phase inputs will be ignored. The
current transformer is placed on the A phase leads connecting to the load. See
the appropriate diagram above and ignore the B and C phase inputs. For a single
phase input, the PT and CT must be monitoring the same phase. During control
Configuration the software must be selected to use Single Phase. The single
phase monitoring is applied to 3 phase machines, it is not intended for single
phase machines.

NOTE
The EGCP-3 power calculations are based on a per-phase calculation. When
a single phase input is used the displayed values will be 1/3 of the total
device levels. Therefore the entered CT ratio or the total power level(s) for
the mains or generator will have to be adjusted to display actual 3∅ device
power levels.

MPU (Speed) Input

The EGCP-3 accepts passive magnetic pickup (MPU) inputs for speed sensing.
It is not recommended that gears mounted on an auxiliary shaft be used to sense
speed. Auxiliary shafts tend to turn more slowly than the rotor or crankshaft
(reducing speed sensing resolution) and have coupling gear backlash, resulting
in less than optimum speed detection. For safety purposes, it is also not
recommended that the speed sensing device sense speed from a gear coupled
to a generator or mechanical drive side of a system.

Analog Inputs
The Analog Inputs may be current or voltage type. If a current input is used, a
jumper is installed at the terminal block, and the software must be selected for
current. This allows the EGCP-3 to use the applicable hardware calibration
values. If a voltage input is needed, the jumper must be removed, and the
software must be selected for voltage.

When the EGCP-3 inputs are configured (see Operator Manual), the engineering
unit values are entered for the sensor at minimum (1 v or 4 mA) and at maximum
(5 V or 20 mA).

All analog inputs are calibrated using the entered engineering unit, and are not
affected by the American or Metric selection.

The Analog Inputs may be used with a two-wire ungrounded (loop powered)
transducer or isolated (self-powered) transducer. See transducer wiring below for
typical wiring. If interfacing to a non-isolated device that may have the potential of
reaching over 10 Vdc with respect to the control’s common, the use of a loop
isolator is recommended to break any return current paths, which could produce
erroneous readings. Loop power must be provided from an external source.

Speed Bias Output

The Speed Bias output allows the EGCP-3 to control the speed and load of the
generator. The Speed Bias output is not used on the MC model. The Speed Bias
can be configured one of four types of outputs: 4–20 mA, 0–5 V, ±3 V, PWM. Full
range of the selected speed bias output should be approximately ±10% or less
change in rated speed. The amount of speed change is a function of the speed
control used. The ±3 V output works with Woodward speed controls and others
designed for a bipolar reference bias. The 0–5 V output works with Detroit Diesel
(DDEC) speed controls and others designed for a unipolar reference bias. The
4–20 mA output is a standard current driver output for speed controls like the
Caterpillar Gas Engine control system and others. The PWM output is 5 V and
500 Hz and will work with Caterpillar ADEM speed controls. Both the
configuration and the wiring must be changed to switch between current and
voltage outputs. Only the configuration must be changed to switch between the
voltage outputs and the PWM output.

Voltage Bias Output

The Voltage Bias allows the EGCP-3 to vary the generator voltage level to
control the reactive load on the generator. The MC model does not use the
voltage bias output. The Voltage Bias can be configured one of four types of
outputs: 4–20 mA, ±1 V, ±3 V, ±9 V. The output mode selected should be
determined based on the voltage regulator specifications. Minimum to maximum
voltage bias output change from the EGCP-3 should be approximately ±10%
change in rated generator voltage. Both the configuration and the wiring must be
changed to switch between current and voltage outputs. Only the configuration
must be changed to switch between the differing voltage outputs.

Analog Outputs
There are four analog outputs that may be assigned to a number of functions.
Each output is a 4–20 mA current source. The Analog Outputs may be used with
a two-wire ungrounded device or isolated device. If interfacing to a non-isolated
device, the use of a loop isolator is required. The chart below give the
parameters that may be configured for analog output, The scale or range of each
parameter can also be changed, i.e. a frequency read out may be set for 57 to 63
Hz, or 30 to 65 Hz.

Discrete Inputs
There are 16 discrete inputs; five are preconfigured for a fixed function and the
remaining eleven may be configured as needed. All sixteen inputs are
individually optically isolated; however, all sixteen share a common power supply
return. The inputs expect 24 Vdc for an asserted state.

Input thresholds < 8 Vdc = “OFF”
> 16 Vdc = “ON”
Input current 3 mA @ 24 Vdc
Contact voltage 24 Vdc isolated
Max input voltage 28 Vdc
Isolation voltage 500 Vac, all channels are isolated from the other I/O

An external 18–28 Vdc power source can be used to source the circuit wetting
voltage for the discrete inputs. Due to circuit isolation, the external power supply
common must be connected to the EGCP-3 terminal 25 as shown in the wiring
diagrams below. However, for EMC Compliance, the on board, isolated, +24 Vdc
supply is recommended for use as the contact wetting voltage. The internal
supply should only be used for the discrete inputs as shown in the diagrams; use
in other, unrelated, circuits could overload the supply or create ground loops. The
internal, isolated, supply is limited to approximately 300 mA maximum.

Pre-configured Inputs
The first five discrete inputs are pre-configured for a fixed function. They cannot
be reprogrammed to another function. The operation of each is described in the
appropriate section of the EGCP-3 Operation manual. Two diagrams are shown;
the one on the left shows use the internal wetting supply voltage, and the other
uses an external supply. The two are mutually exclusive.

The E-stop input is Active Low, normally closed. It will generate an E-stop alarm
if the connection is broken. The other inputs are Active High, normally open.

There are 12 discrete outputs. Some of which are preconfigured for a fixed
function but the remaining may be configured as needed, depending on the
EGCP-3 model. All twelve outputs are individually optically isolated. However, all
twelve share a common power supply and return circuit. Each output uses a
thermally protected MOSFET that will pulse the circuit if the current limit is
exceeded. An over-current condition on one output will not affect the other
outputs. The output will be pulsed continuously until the current requirement is
reduced, allowing the output to operate normally again.

Communication Ports
There are three serial ports on the EGCP-3. They may all be used
simultaneously and may all be configured independently. Performance of any
one port will depend on how many ports are in use and the port traffic. Ports 1
and 2 may be configured as RS-232, RS-422, or RS-485 to match the intended
application. All ports are optically isolated from each other.

Any port configured as RS-232 will meet the RS-232C standard for
communications. The wiring shall meet the requirements of EIA RS-232. This
standard states a maximum cable length of 15 m (50 ft) with a total capacitance
less than 2500 pF and a data rate not exceeding 56 kbps. All EGCP-3 serial
ports may be configured for data rates up to 115 200 bps but may not function
properly at this high data rate when a full 15 meters of cable length is used. Do
not leave an RS-232 null modem cable attached to the EGCP-3 if it is removed
from the PC, to avoid the possibility of EMC noise being introduced to the
EGCP-3.

Woodward 49
EGCP-3 Installation Manual 26122
Any port configured as RS-422 or RS-485 meets the ANSI standards for this type
of communications. The wiring shall be one continuous cable between nodes and
shall meet the requirements of EIA RS-422 or EIA RS-485 for 500 kbps.
However, one half of the cable length limits is recommended due to harsh
environments typical of prime mover installations as follows:

The last unit in the network chain, and only the last unit, should have its receiver
terminated with a resistor. If the EGCP-3 is the last unit, installing jumpers as
shown on the following diagrams may use the internal resistors

Configurable Port (Serial 1)

This port may be configured to use the Modbus RTU protocol or Woodward’s
ServLink protocol. If it is configured as a Modbus RTU port, it will have the same
address as the port 2 Modbus port described below. However, although they
share the same address, all messaging is independent and they are physically
and electrically isolated.

The RS-232 port configuration is defaulted at 57.6 kbps, no parity, 8 data bits,
and 1 stop bit. The RS-422 and RS-485 port baud rate is shared with the RS-232
configuration and hence also defaults to 57.6 kbps.

Modbus Port (Serial 2)

This port may only be used as a Modbus RTU port. It will have the same address
as the Serial 1 Modbus port described above, if that port is also configured to use
Modbus. However, although they share the same address, all messaging is
independent and they are physically and electrically isolated.

The port may be configured for RS-232, RS-422, or RS-485 by using the correct
wiring connections and selecting the correct protocol mode. The RS-232 port
configuration is defaulted at 9600 bps, no parity, 8 data bits, and 1 stop bit. The
RS-422 and RS-485 port baud rate is shared with the RS-232 configuration and
hence also defaults to 9600 kbps.

RS-232 Configuration Port (Serial 3)

This port may only be used as a Woodward ServLink port. Its primary purpose is
for configuration using a PC with Woodward’s Watch Window. However, it may
also be connected to a PC based HMI for local configuration and monitoring.

The port is fixed as an RS-232 port only. The RS-232 port configuration is
defaulted at 115200 bps, no parity, 8 data bits, and 1 stop bit. A Null Modem
cable must be used to connect to this port. The EGCP-3 has a standard DB-9
Female receptacle. It is best to use a metal shell connector at both ends with the
shell connected to the cable shield but isolated from the ground signal wire. The
shell of the 9-pin D-sub on the EGCP-3 is chassis grounded.

LON Communication Port

The LON port is used to communicate with up to 16 other EGCP-3 devices. The
LON allows controls to share start/stop sequencing, breaker status, and load
share information between generator sets. When connected to an optional
Master Control (MC) the LON is used to control the operation and sequencing of
the LS units. The LON communication is also compatible with Digital
Synchronizer and Load Control (DSLC) devices. When an EGCP-3 is the last
device of the LON string, the termination jumper at 48 and 49 should be installed

Chapter 3.
Modbus Communications

General Information
The Serial 1 port is open to customer use for a variety of applications. It will
communicate with the MODBUS RTU protocol or the Woodward ServLink
protocol, and may be configured to do so using RS-232, RS-422, or RS-485 to
match the customer’s hardware. The Serial 2 port will only communicate with the
MODBUS RTU protocol and may be configured to do so using RS-232, RS-422,
or RS-485 to match the customer’s hardware. This chapter addresses the
Modbus functionality of serial port 1 and 2.

The Modbus ID (node address) may be configured to suit the customer’s

application. It is adjustable from 1 to 247. This address identifies the Modbus
Slave to the Modbus Master. The Modbus address chosen for any particular
EGCP-3 panel should be unique from any other devices on the Modbus network.
This address is also used as the Modbus address when Serial 1 is configured as
a Modbus port.

A Modbus Time-out is configurable from Watch Window. This item is the time, in
seconds, which the EGCP-3 panel will wait before either receiving a valid
message from the Modbus master, or indicating a Modbus failure. If Serial 1 is
configured as a Modbus port, it will use the same timeout. An alarm can be
configured to give an indication or shutdown when a Port Failure (failure to
receive a valid message from the master) occurs. The Port Failure is a latching-
type indication, and requires the Modbus Reset menu item to be toggled from
True to False in order to reset. The Modbus Reset is located in the
Communications service menu. It is used to reset any failures indicated on the
Modbus serial communications, and also to restart the Modbus Time-out timer.
The Modbus Reset should be left at FALSE, and only turned to TRUE to provide
a reset action on the Modbus. Once the reset is accomplished, the Modbus
Reset must be taken back to False once again. Reply Time-out, Delay, and
Number of Retries for the Modbus Master must be configured to meet the
requirements of the entire Modbus network and the devices communicating on
that network. Both Serial 2 and Serial 1 will be reset (if Serial 1 is configured for
Modbus) when a Reset is performed.

Both Serial 2 and Serial 1 ports will have access to the same data. The timeout,
reset, and Modbus ID configurations are shared between Serial 1 and Serial 2.

All serial ports have independently configurable baud rates. They may only be
configured from Watch Window. They support baud rates from 4800 baud to 115
200 baud. However, no two ports should be set to 115 200 simultaneously. Two
or more ports may be set to 57 600 simultaneously.

The sections below describe what is found in the Modbus tables. The actual
tables are found in Appendix D and E for the EGCP-3 LS and MC respectfully.

56 Woodward
Manual 26122 EGCP-3 Installation

Communication Configuration
The configuration elements for the serial ports capable of Modbus are shown in
the tables below.

Item Semantics Min Max Default

Serial 1 Type RS-232, RS-422, RS-485 RS-422
Serial 1 Mode Modbus, ServLink Modbus ServLink Modbus

11 57,600

9 19,200
8 9600
7 4800

Boolean Write
Using Modbus, it is possible for the master to send commands to the EGCP-3
slave. The commands that are allowed are shown in the Boolean Write table
below. For safety, when changing the Mode Switch position over Modbus, the
physical switch must be in the auto position; otherwise the EGCP-3 will not
relinquish control to Modbus. All BW data are Boolean data types.

A physical discrete input will always take precedence over the Modbus command
for that same function. The exception here is the Auto input of the mode switch
must be maintained and the Modbus can select a different mode. When a Control
mode or Load mode is selected, the last command will remain active until the
disable command is received. The control will select the OFF mode, until the
external switch is moved, or another mode is enabled through Modbus. The last
synchronizer mode selected from the HMI or Modbus will remain the active
mode.

A command to raise or lower voltage/speed will be treated as if it were a physical

digital input. A raise/lower command is given as long as the switch input is
“True”, and turned off when the next Modbus write indicates a “False”. If another
Modbus write is not seen within 1 second, the command is considered “False”.

Woodward 57
EGCP-3 Installation Manual 26122

Boolean Read
The boolean read table contains boolean values such as alarm states, digital
inputs status, etc. The interpretation of a 0 or 1 in response is indicated in the
semantics field. Functions that appear to indicate a physical switch position will
indicate the functional position even if not mapped to a physical I/O point. All BR
data is Boolean data type.

Alarm states indicate ‘Active’ when the alarm conditions have been met unless
that alarm is configured for “disabled”. An alarm condition could become active
and deactivate again within a single Modbus update time depending on the
frequency at which the master is polling. Therefore, to avoid confusion, all alarm
conditions will be latched for one second or one Modbus poll cycle after the
occurrence of the alarm (whichever comes first) as seen from Modbus. If the
alarm condition no longer exists after this poll cycle, the Modbus alarm indication
will reset to ‘Not Active’ as the alarm condition is no longer true.

Analog Read
The analog read table contains integer values such as Voltages, Currents, etc
that are scaled to eliminate decimal places. The scaling (if any) is described in
the scale field. Minimum and maximum values indicated are shown with scaling.
Values with scaling have been multiplied by the value indicated before being
transmitted, and should be divided by the same scale value (by the receiving
device) in order to represent the actual value. A blank in this column is a scale of
1.0. Some scaled values are scaled by the value in another parameter, and
flagged by “Note A” through “Note F”. The Notes at the end of the table gives the
address (30xxx) of the scale to use for the flagged values. Those special cases
are individually described or described in the Units section following the table. All
AR data is integer data type (16-bits, signed).

The definitions of values used to communicate the Mode, State and Alarm Action
of the EGCP-3 are also described. The semantics column will flag the table
containing the applicable definition.

Analog Write
The analog write table contains integer values such as load references or
process references that are scaled to eliminate decimal places. The scaling (if
any) is described in the scale field. Minimum and maximum values indicated are
shown with scaling. All AW data is integer data type (16-bits, signed) and must
be sent as such. Data sent to a scaled address must first be multiplied by the
indicated amount because the EGCP-3 will divide the value by the indicated
amount upon receipt.

Enumerated Lists
The following lists and tables define the enumerated values and their respective
definition. These values are used by an HMI for display of representative wording
for the function, mode, or state being displayed.

58 Woodward
Manual 26122 EGCP-3 Installation

Units
All metered voltage, current, and power values are provided without scaling and
need to be multiplied by a scaling value. The scaling is dependent on the units
for the measured parameter. For example, if the units are ‘kilo’, the parameter
should be multiplied by 1000 to represent the actual value (KW, KV, KA). If the
units are ‘Mega’, the parameter should be multiplied by 1 000 000 to represent
the actual value.

All values that report voltage will use the same units as defined by the voltage
units.

All values that report current will use the same units as defined by the current
units.

All power values (Watts, VAR, VA) will use the same units as defined by the
power units.

Unit Value Unit Modifier Units Definition

1 None No scaling
2 Kilo Multiply by 1000
3 Mega Multiply by 1 000 000
4 Giga Multiply by 1 000 000 000

Synchroscope Definition
Phase Angle: The Phase Angle reading is a value from 0 (phase matched at
12:00 on a synchroscope) to ±180 degrees. Negative degree measurements
occur in the right half of the synchroscope, while positive degree measurements
occur in the left half of the synchroscope. Therefore, a generator with a positive
slip frequency (clockwise synchroscope rotation) would display a sequence of
numbers such as ….0, –30, –60, –90, –120, –150, –180, 150, 120, 90, 60, 30,

ServLink Server

General Information
The EGCP-3 has two ports that may be used as Woodward ServLink servers.
Serial 3 port is fixed as a ServLink only port. This is the port that is intended to be
used for configuration and must be used for downloading an application or saved
configuration. It is also fixed as a RS-232 port since configuration and download
are done from a PC. A standard DB-9 serial connection is provided.

The Serial 1 port is open to a variety of applications. It will communicate with the
Modbus RTU protocol or the Woodward ServLink protocol and may be
configured to do so using RS-232, RS-422, or RS-485 to match the customer’s
hardware. This port can be used to communicate with a PC, PLC, an HMI, or
distributed I/O. This chapter addresses only the ServLink functionality.

Configuration through ServLink

Watch Window is the PC based configuration program that is used to configure
the EGCP-3. Watch Window Standard is shipped with the EGCP-3. All
configurable parameters that may be configured through the front panel are also
available in Watch Window. There are also additional configurable parameters
available in Watch Window that are not present on the front panel display.

The organization of tunable parameters is important because of their large

number and because of the front panel display. Parameters are separated into
Configure and Service blocks. All parameters that should not be changed while
the engine is running are placed in Configure blocks. Configure blocks require IO
lock to be set in order to allow changes in a parameter. IO Lock is a state of the
EGCP-3 processor that causes all of the outputs to be in their “off” condition, and
inputs are not monitored. The Front panel display “First Time Startup” menu
items require that the engine speed be zero before allowing items to be tuned.
The EGCP-3 does not need to be in IO Lock to tune items in this menu from the
front panel. All other Watch Window menu tunable parameters are provided in
Service Blocks.

CAUTION—SERVLINK ACCESS
ServLink allows access to its parameters through a serial port without
password or security restrictions. Access to the ServLink connected devices
should be limited as necessary for the individual installation.

The Service and Configure blocks are designed to mimic the front panel display
menu structure as much as possible. This structure allows you to use the Quick
Configure feature of Watch Window to create logical and manageable sheets
(tabs) of parameters. The grouping of items in a Watch Window sheet is the
same as the grouping on the front panel display menus. The table below
indicates the sheets that are created by a Quick Configure agent.

The order of the sheet names is important to match the front panel order, which
is why all menus are preceded with a symbol and letter. These allow Watch
Window to use an alphabetical order to sort the sheets logically.

Due to the nature of how parameters are configured through Watch Window,
some parameters will be configured by changing a value from an enumerated list
as seen in the previous chapter. In these cases there will also be a monitor-only
text string returned directly below the tunable parameter showing the action
selected. The Watch Window string will be the same string as shown on the
EGCP-3 display when this parameter is configured from the front keypad. In
some cases, an appropriate monitored data value is also included on the same
sheet. Monitored parameters to assist with troubleshooting are available on the
status screens in Watch Window. These status parameters are also available
from the EGCP-3 front display panel.

The front panel and Watch Window menus will not be presented in this chapter.
See the appropriate chapters in the Operation Manual for configuration and
monitoring details.

ServLink Data
Note: Information in this section is NOT required to use Woodward Watch
Window software for configuration and monitoring.

When the application requires monitoring and tuning of the genset parameters by
an external computer device, ServLink is required for that communication. When
serial 1 port is used as a ServLink port, it will serve monitoring data to a local
HMI that can be used as the main user interface. Since these applications may
have the front panel display hidden, all front panel data are available through the
ServLink port as well as other useful data. This port will also allow remote
start/stop control provided the EGCP-3 control switch is in the Auto position.

Serial port 3 may also be used to drive a local HMI, but it is generally
recommended to leave serial port 3 available for configuration.

The available data is provided below in tables split by data type and read/write
status. The Woodward ServLink server must be running on the connected PC in
order for this data to be available to an application on the same PC. The server
provides the data in DDE format. The ServLink ID in the tables below is the DDE
address for the data.

Service Options

Product Service Options

The following factory options are available for servicing Woodward equipment,
based on the standard Woodward Product and Service Warranty (5-01-1205)
that is in effect at the time the product is purchased from Woodward or the
service is performed:
• Replacement/Exchange (24-hour service)
• Flat Rate Repair
• Flat Rate Remanufacture

If you are experiencing problems with installation or unsatisfactory performance

of an installed system, the following options are available:
• Consult the troubleshooting guide in the manual.
• Contact Woodward technical assistance (see “How to Contact Woodward”
later in this chapter) and discuss your problem. In most cases, your problem
can be resolved over the phone. If not, you can select which course of
action you wish to pursue based on the available services listed in this
section.

Replacement/Exchange
Replacement/Exchange is a premium program designed for the user who is in
need of immediate service. It allows you to request and receive a like-new
replacement unit in minimum time (usually within 24 hours of the request),
providing a suitable unit is available at the time of the request, thereby minimizing
costly downtime. This is also a flat rate structured program and includes the full
standard Woodward product warranty (Woodward Product and Service Warranty
5-01-1205).

This option allows you to call in the event of an unexpected outage, or in

advance of a scheduled outage, to request a replacement control unit. If the unit
is available at the time of the call, it can usually be shipped out within 24 hours.
You replace your field control unit with the like-new replacement and return the
field unit to the Woodward facility as explained below (see “Returning Equipment
for Repair” later in this chapter).

Charges for the Replacement/Exchange service are based on a flat rate plus
shipping expenses. You are invoiced the flat rate replacement/exchange charge
plus a core charge at the time the replacement unit is shipped. If the core (field
unit) is returned to Woodward within 60 days, Woodward will issue a credit for
the core charge. [The core charge is the average difference between the flat rate
replacement/exchange charge and the current list price of a new unit.]

Return Shipment Authorization Label. To ensure prompt receipt of the core,

and avoid additional charges, the package must be properly marked. A return
authorization label is included with every Replacement/Exchange unit that leaves
Woodward. The core should be repackaged and the return authorization label
affixed to the outside of the package. Without the authorization label, receipt of
the returned core could be delayed and cause additional charges to be applied.

Manual 26122 EGCP-3 Installation

Flat Rate Repair

Flat Rate Repair is available for the majority of standard products in the field.
This program offers you repair service for your products with the advantage of
knowing in advance what the cost will be. All repair work carries the standard
Woodward service warranty (Woodward Product and Service Warranty
5-01-1205) on replaced parts and labor.

Flat Rate Remanufacture

Flat Rate Remanufacture is very similar to the Flat Rate Repair option with the
exception that the unit will be returned to you in “like-new” condition and carry
with it the full standard Woodward product warranty (Woodward Product and
Service Warranty 5-01-1205). This option is applicable to mechanical products
only.

Returning Equipment for Repair

If a control (or any part of an electronic control) is to be returned to Woodward for
repair, please contact Woodward in advance to obtain a Return Authorization
Number. When shipping the item(s), attach a tag with the following information:
• name and location where the control is installed;
• name and phone number of contact person;
• complete Woodward part number(s) and serial number(s);
• description of the problem;
• instructions describing the desired type of repair.

CAUTION—ELECTROSTATIC DISCHARGE
To prevent damage to electronic components caused by improper handling,
read and observe the precautions in Woodward manual 82715, Guide for
Handling and Protection of Electronic Controls, Printed Circuit Boards, and
Modules.

Packing a Control
Use the following materials when returning a complete control:
• protective caps on any connectors;
• antistatic protective bags on all electronic modules;
• packing materials that will not damage the surface of the unit;
• at least 100 mm (4 inches) of tightly packed, industry-approved packing
material;
• a packing carton with double walls;
• a strong tape around the outside of the carton for increased strength.
