WARNING
Read this entire manual and all other publications pertaining to the work to be performed before instal-
ling, operating, or servicing this equipment. Practice all plant and safety instructions and precautions.
Failure to follow instructions can cause personal injury and/or property damage.
The engine, turbine, or other type of prime mover should be equipped with an overspeed (overtempera-
ture, or overpressure, where applicable) shutdown device(s), that operates totally independently of the
prime mover control device(s) to protect against runaway or damage to the engine, turbine, or other
type of prime mover with possible personal injury or loss of life should the mechanical-hydraulic gov-
ernor(s) or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), the linkage(s),
or the controlled device(s) fail.
Any unauthorized modifications to or use of this equipment outside its specified mechanical, electrical,
or other operating limits may cause personal injury and/or property damage, including damage to the
equipment. Any such unauthorized modifications: (i) constitute "misuse" and/or "negligence" within
the meaning of the product warranty thereby excluding warranty coverage for any resulting damage,
and (ii) invalidate product certifications or listings.

CAUTION
To prevent damage to a control system that uses an alternator or battery-charging device, make sure
the charging device is turned off before disconnecting the battery from the system.
Electronic controls contain static-sensitive parts. Observe the following precautions to prevent dam-
age to these parts.
Discharge body static before handling the control (with power to the control turned off, contact a
grounded surface and maintain contact while handling the control).
Avoid all plastic, vinyl, and Styrofoam (except antistatic versions) around printed circuit boards.
Do not touch the components or conductors on a printed circuit board with your hands or with
conductive devices.

Intended Use: This control is intended to be operated according to the guidelines described in this manual. The
prerequisite for a proper and safe operation of the product is correct transportation, storage, and installation as
well as careful operation and maintenance.

NOTE
This manual has been developed for a control fitted with all available options. Inputs/outputs, func-
tions, configuration screens and other details described, which do not exist on your control may be ig-
nored.
The present manual has been prepared to enable the installation and commissioning of the control.
Due to the large variety of parameter settings, it is not possible to cover every combination. The ma-
nual is therefore only a guide. In case of incorrect entries or a total loss of functions, the default set-
tings can be taken from the list of parameters located in the appendix of the Configuration manual.

Chapter 2.
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. Opening the Control unit will void the warranty!

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:

Make sure that the unit is completely de-energized (all connectors have to be pulled off).

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

Do not touch the electrical conductors, connectors, or components with conductive devices or with
bare 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 unit, place it in the an-
tistatic protective bag.

WARNING
To prevent damage to electronic components caused by improper handling, read and observe the pre-
cautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed
Circuit Boards, and Modules.

Installation

For installation into a door panel proceed as follows:

1. Panel cut-out B
Cut out the panel according to the dimensions in Figure 3-1. b

h H

2. Insert control into cut-out Move housing into panel

Insert the control into the panel cut-out. Verify that the control fits cor-
rectly in the cut-out. If the panel cut-out is not big enough, enlarge it
accordingly.

3. Attach mounting clamps a) Attach clamp here

Rotate clamps according to the picture on the right until they snap into
the mounting cones.

b) Rotate clamp until front

nut of the clamp locks into
front cone

4. Screw clamps Screw down until the

housing fits into

Tighten the screw clamps until the housing is pressed and fixed against the panel

the panel. Be careful not to over tighten the clamps, which can unsnap
the front frame from the housing. If this happens remove the control
from the panel and reattach the frame by pressing firmly against the
housing.

Note: Using the gasket kit (P/N 8923-1043) increases the IP protection from IP42 to IP54 from front. Mounting
of the gasket is described in the manual supplied with the gasket kit.

Wiring Diagrams - Overview

WARNING
A circuit breaker must be located near to the control and in a position easily accessible to the operator.
This must also bear a sign identifying it as an isolating switch for the control.

NOTE
Connected inductances (e.g. operating current coils, undervoltage tripping devices, auxiliary contac-
tors, and/or power contactors) must be wired with an appropriate interference protection.

Table 5-3: Terminal assignment - generator voltage measuring

NOTE
A GCP-30 controller with 400V PT inputs and potential transformers with 100V secondary outputs must
be used for 480V delta applications. The GCP-30 will not properly protect the generator or system from
overvoltage fault conditions if a GCP-30 with 100V PT inputs is used with 100V potential transformers
or a 400V PT input unit is directly connected to a 480V system. The 100V model inputs are limited to
measuring voltage up to 125V and an overvoltage fault would exceed this range. The 400V model of the
GCP-30 is also unable to monitor for overvoltage faults if potential transformers are not utilized due to
the overvoltage fault exceeding the voltage monitoring range of maximum 500V as well.

NOTE
If a three-wire system is connected, terminal 0 must remain disconnected. If terminal 0 is connected,
the control may monitor a voltage that exceeds the permissible limits.

CAN Bus Topology

NOTE
Please note that the CAN bus must be terminated with an impedance which corresponds to the wave
impedance of the cable (e.g. 120 ). The CAN bus is terminated between CAN-H and CAN-L.
The two CAN-H and CAN-L terminals in the unit are hard-wired internally and can be used to feed the
CAN bus through. However, if you want to avoid a break of the bus when a unit is unplugged, you may
connect the incoming and outgoing bus line in the same terminal.

Figure 5-23: Interfaces - CAN bus topology

Possible CAN Bus Problems

If no data is transmitted on the CAN bus, check the following for common CAN bus communication problems:

- T structure bus is utilized (stub-end feeders or branch lines are not recommended)
- CAN-L and CAN-H are interchanged
- Not all devices on the bus are using identical Baud rates
- Correct terminating resistor(s) is/are missing
- Incorrect baud rate (too high) for length of CAN bus
- The CAN bus cable is co-routed with power cables

Woodward recommends the use of twisted-pair cables for the CAN bus (i.e.: Lappkabel Unitronic LIYCY (TP)
220.25, UNITRONIC-Bus LD 220.22).

Maximum CAN Bus Length

The maximum length of the communication bus wiring is dependent on the configured Baud rate. Refer to Table
5-24 for the maximum bus length (Source: CANopen; Holger Zeltwanger (Hrsg.); 2001 VDE VERLAG GMBH,
Berlin und Offenbach; ISBN 3-8007-2448-0).
Baud rate Max. length
1000 kbit/s 25 m
800 kbit/s 50 m
500 kbit/s 100 m
125 kbit/s 250 m
50 kbits/s 1000 m
20 kbit/s 2500 m
Table 5-24: Maximum CAN bus length

The maximum specified length for the communication bus wiring might not be achieved if poor quality wire is
utilized, there is high contact resistance, or other conditions exist. Reducing the baud rate may overcome these is-
sues.

Manual 37364A GCP-30 Packages - Genset Control

DPC - Direct Configuration Interface

NOTE
To configure via the configuration interface (direct configuration), you need the configuration cable
(part number 5417-557), the program LeoPC1 (delivered with the cable), and the corresponding confi-
guration files. Please consult the online help installed when the program is installed for a description
of the LeoPC1 program and its setup.
If the parameter "Direct para." is enabled on the control, communication via the CAN bus interface on
terminals X1/X5 is disabled.
If the control unit detects that the engine is running (ignition speed exceeded), the direct configuration
port is disabled.
