Manual E 82 001-e / 11-10

The appropriate manuals must be thoroughly studied before instal-
lation, initial start-up and maintenance.
All instructions pertaining to the system and safety must be followed in
full. Non-observance of the instructions may lead to injury to persons
and/or material damage.
HEINZMANN shall not be held liable for any damage caused through
non-observance of instructions.
Independent tests and inspections are of particular importance for all
applications in which a malfunction could result in injury to persons or
material damage.
All examples and data, as well as all other information in this manual
are there solely for the purpose of instruction and they may not be used
for special application without the operator running independent tests
and inspections beforehand.
HEINZMANN does not guarantee, neither expressly nor tacitly, that
the examples, data or other information in this manual is free from er-
ror, complies with industrial standards or fulfils the requirements of any
special application.

To avoid any injury to persons and damage to systems, the following

monitoring and protective systems must be provided:
 overspeed protection independent of the rpm controller
HEINZMANN shall not be held liable for any damage caused through
missing or insufficiently rated overspeed protection.
 thermal overload protection
The following must also be provided for alternator systems:
 Overcurrent protection
 Protection against faulty synchronisation for excessively-large fre-
quency, voltage or phase difference
 Directional contactor
The reasons for overspeeding may be:
 Failure of positioning device, control unit or its auxiliary devices
 Linkage sluggishness and jamming

The following must be observed before an installation:

 Always disconnect the electrical mains supply before any interven-
tions to the system.
 Only use cable screening and mains supply connections that corre-
spond with the European Union EMC Directive
 Check the function of all installed protection and monitoring systems
Please observe the following for electronically controlled injection
(MVC):
 For common rail systems each injector line must be equipped with a
separate mechanical flow-rate limiter.
 For unit pump (PLD) and pump-injector unit (PDE) systems, the
fuel enable is first made possible by the solenoid valve’s control
plunger motion. This means that in the event of the control plunger
sticking, the fuel supply to the injection valve is stopped.

As soon as the positioning device receives power, it can actuate the

controller output shaft automatically at any given time. The range of the
controller shaft or control linkage must therefore be secured against un-
authorised access.

HEINZMANN expressly rejects any implied guarantee pertaining to

any marketability or suitability for a special purpose, including in the
event that HEINZMANN was notified of such a special purpose or the
manual contains a reference to such a special purpose.

HEINZMANN shall not be held liable for any indirect and direct dam-
age nor for any incidental and consequential damage that results from
application of any of the examples, data or miscellaneous information
as given in this manual.

HEINZMANN shall not provide any guarantee for the design and planning
of the overall technical system. This is a matter of the operator its planners
and its specialist engineers. They are also responsible for checking whether
the performances of our devices match the intended purpose. The operator is
also responsible for a correct initial start-up of the overall system.

2 Safety Instructions and Related Symbols

This publication offers practical safety instructions to indicate the unavoidable residual risks
involved when operating the machine. These residual risks involve hazards to

- Personnel
- Product and machine
- The environment

The primary aim of the safety instructions is to prevent personal injury!

The signal words used in this publication are specifically designed to direct your attention to possi-
ble damage extent!

DANGER indicates a hazardous situation the consequence of which could

be fatal or severe injuries if it is not prevented.

WARNING indicates a hazardous situation which could lead to fatal inju-

ry or severe injuries if it is not prevented.

CAUTION indicates a hazardous situation which could lead to minor in-

juries if it is not prevented.

NOTICE indicates possible material damage.

Safety instructions are not only denoted by a signal word but also by hazard
warning triangles. Red hazard warning triangles indicate immediate danger to
life. Yellow hazard warning triangles indicate a possible risk to life and limb.
Hazard warning triangles can contain different symbols to illustrate the dan-
ger. However, the symbol used is no substitute for the actual text of the safety
instructions. The text must therefore always be read in full!

This symbol does not refer to any safety instructions but offers important
notes for better understanding the functions that are being discussed.
Note
They should by all means be observed and practised. The respective text is
printed in italics.

 2 Safety Instructions and Related Symbols

In this publication the Table of Contents is preceded by diverse instructions that among
other things serve to ensure safety of operation. It is absolutely imperative that these
hints be read and understood before commissioning or servicing the installation.

2.1 Basic Safety Measures for Normal Operation

 The installation may be operated only by authorized persons who have been duly
trained and who are fully acquainted with the operating instructions so that they are
capable of working in accordance with them.
 Before turning the installation on please verify and make sure that
- only authorized persons are present within the working range of the engine;
- nobody will be in danger of suffering injuries by starting the engine.
 Before starting the engine always check the installation for visible damages and make
sure it is not put into operation unless it is in perfect condition. On detecting any faults
please inform your superior immediately!
 Before starting the engine remove any unnecessary material and/or objects from the
working range of the installation/engine.
 Before starting the engine check and make sure that all safety devices are working
properly!

2.2 Basic Safety Measures for Servicing and Maintenance

 Before performing any maintenance or repair work make sure the working area of the
engine has been closed to unauthorized persons. Put on a sign warning that mainte-
nance or repair work is being done.
 Before performing any maintenance or repair work switch off the master switch of the
power supply and secure it by a padlock! The key must be kept by the person perform-
ing the maintenance and repair works.
 Before performing any maintenance and repair work make sure that all parts of engine
to be touched have cooled down to ambient temperature and are dead!
 Refasten loose connections!
 Replace at once any damaged lines and/or cables!
 Keep the cabinet always closed. Access should be permitted only to authorized pers-
sons having a key or tools.
 Never use a water hose to clean cabinets or other casings of electric equipment!

 3 Application

3 Application
The electronic HEINZMANN speed governors of the series E 1-F and E 2-F are all-electronic
and therefore do not require mechanical drives. The respective electric actuators StG 1-F and
StG 2-F are actively positioned in either direction by a power output stage.
This provides for very simple and cost-efficient installation on the engine so that these gover-
nors can be used for relatively simple governing tasks.
Their use is especially recommendable when the requirements with respect to governing qual-
ity are high. These governors offer very short response times with little overshooting and high
accuracy of speed control both with and without droop as may be required by the application.
Tasks such as automatic synchronization, load sharing, load anticipation, etc., can be carried
out in a very simple manner by means of a series of accessories (please refer to our leaflet
“Accessories“ and to our manuals for accessories).

 5 Mode of Operation

5 Mode of Operation
The electronic speed governors of the basic systems E 1-F and E 2-F are PID-governors de-
signed for diesel or gas engines. The actuator output shaft rotation is 68°, thus allowing direct
coupling to a carburator butterfly valve or a gas mixer.
Current speed is normally sensed as magnetic pickup frequency by means of a contactless
inductive sensor on the starting gear ring and compared with set speed. If there is a difference
between current and set speed the actuator is made to react accordingly and to eliminate the
speed deviation.
The governors are designed as PID controls that depending on the specific application allow
of operation both by the functions droop zero and by droop.
Droop zero is to be understood as adjusting speed to the pre-defined speed setpoint independ-
ently of engine load (for instance, 1,500 rpm for generator sets).
Droop, i.e. a permanent speed deviation in dependence on engine load, is required for vehicle
applications as well as for retrofitting or modernizing existing generator sets where a me-
chanical speed governor has been replaced by an electronic one.
The basic systems E 1-F and E 2-F can be combined with accessories such as synchronizers,
load measuring/sharing units and current anticipation units, etc.

5.1 Frequency Range

The control units are designed for a frequency range of:
Standard f = 3100 – 7000 Hz

Other frequency ranges are available on request.

5.2 Start Fuel Limitation

To prevent heavy smoke bursts during the engine starting phase, particularly with super-
charged diesel engines, the start fuel limitation function can be activated by applying bat-
tery voltage to the switch input (green cable) until the starting procedure is completed.
With generator sets, it is recommended to install an interconnection with the generator
breaker (opening contact keeping the limitation active until the breaker is closed) whereas
for other applications a speed dependent switching point is to be provided that will turn off
this limitation when idling speed (e.g., 800 rpm) is reached.

Basic Systems E 1-F and E 2-F 7

5 Mode of Operation

5.3 Speed Switching Point

The controls E 1-F and E 2-F have an adjustable speed switching point that is capable of
activating an external relay (yellow cable). This switching point is often used to cut off the
starter or to sense over speeding.

7.2 Installation
The installation of the pickup has to be arranged in such a way as to obtain a frequency as
high as possible. The Frequency (by Hz) is calculated according to the formula
n(1 / min)* z
f (Hz) =
60
z = number of teeth on the pickup wheel
Example:
n = 1500
z = 160
1500*160
f = = 4000 Hz
60
It should be taken care that speed can be measured by the pulse pickup without any bias.
For best results therefore, the speed pickup should take engine speed from the crankshaft.
A suitable position for this is, e.g., the starter gear (but not the injection pump wheel).
The pickup gear must consist of magnetic material (e.g., steel, cast iron).

7.3 Tooth Profile

Any tooth profile is admissible. The top width of the tooth should be 2.5 mm minimum,
the gap and the depth of the gap at least 4 mm. For index plates the same dimensions are
valid.
Due to tolerances, a radial arrangement of the magnetic pickup is preferable.

7.4 Clearance of Magnetic Pickup

The distance between the magnetic pulse pickup and the tooth top should range from 0.5 to
0.8 mm. (It is possible to screw the magnetic pickup on till it touches the tooth and then
unscrew it for about half a turn.)

The standard versions of the basic system E 1-F with control unit KG 1-04-F or KG 1-08-F
and of the basic system E 2-F with control unit KG 2-04-F or KG2-08-F are shipped as
idle/maximum speed governors and will therefore not normally require an external setpoint
adjuster except a jumper on the 3-pole setpoint plug.

The setpoint plug with the link must always be connected. When not connected,
the governor will not work. For safety reasons the actuator will then always be in
Note a shutdown condition.

By connecting an external setpoint potentiometer the control unit may be used as a variable
speed governor. The 5 k potentiometers as described in chapter 8.2 provide an adjustment
range of 1:3.
On request, the potentiometers can be supplied with analogue adjustment knob with lock in
place of the standard rotating knob. In this case, ordering specification is SW..-..-m.
Equally, instead of the knob a clamping fixture can be provided. In this case, order specifica-
tion should be SW ..-..-k instead.

8.1 Setpoint Potentiometer for Generator Applicationen with Droop

For generator applications with droop an external potentiometer or motor potentiometer
with 250  is recommended with generator frequency set to 50 Hz when the potentiometer
is in mid-position. The 250  potentiometer will permit of variations of ± 2 Hz (with re-
spect to the generator frequency of 50 Hz).

8.3 Motorized Potentiometer

These potentiometers permit manual adjustment via the potentiometer knob or electrical
adjustment from various positions via 24 V pulses (speed increase/decrease). Motorized
potentiometers with different adjustment times and with or without optional limit switchers
are available. For more information refer to manual E 83 006 - e.

8.4 Electronical Potentiometer

The electronical setpoint potentiometer ESW 1 - 01 may be used as an interconnection unit
between HEINZMANN speed governors and devices by other companies. It will mainly be
used for gensets, perhaps in combination with other synchronizer and load governing
equipment. An internal potentiometer is used to adjust the basic speed which may be de-

creased or increased by pulses from the external equipment. The sensitivity and ramp time
of the unit is adjustable. For more information refer to manual E 97 001 - e.

In case of electrical setpoint units such as SW 09 - URI, ESW 01 - 1, EFP or

other non- HEINZMANN units are used, the common negative for these devices
Note
must be taken from the HEINZMANN governor. If this is not done, differences
in the electrical potential will result in worse governing quality or even in a
failure of the governor.

Actuator StG1-02-F

for Basic System E1-F

Voltage 12 / 24

Figure 10: Sectional Drawing of Actuator StG 1-02-F

A multipolar magnetized permanent magnet is mounted on the actuator shaft. Opposite the
permanent magnet an armature is fixed. When current is fed to the armature, torque in one
direction is obtained. Changing the polarity of the current results in changing the torque di-
rection.
The control feedback is also fixed on the shaft. The actuator has a contactless feedback
system that informs the control unit of the fuel position. Therefore, when speed or load
change, the control unit is able to manipulate the actuator current, so the actuator will be
forced to the required position until there is no difference between set speed and actual
speed.
If the actuator strikes against a stop, as may occur, e.g., under parallel mains operation or
may be caused by engine overload or cylinder failure, the current limitation will take effect
after approx. 20 seconds; by this the current to the actuator is reduced to a value that can-
not harm the motor.
The actuator is maintenance-free.

10 Actuators StG 1-02-F and StG 2-02-F

In altogether, this type of actuator provides the following advantages:

- High regulation power working in both directions.
- Extremely low current consumption during steady state and relatively low current con-
sumption on change of load.
- Indifference to slow voltage changes of the supply; abrupt voltage changes cause gov-
ernor disturbances.

10.2 Mounting
The actuator must be mounted firmly on the engine by means of reinforced brackets. Un-
stable arrangements, as caused by weak bracket material or missing stiffenings, have to be
avoided by all means; they are bound to intensify vibrations, which will lead to premature
wear of the actuator and the connecting linkage!

11 Regulating Linkage

11.1 Length of Lever Arm

The length of the lever arm is determined in such a way that approx. 90 % of the governor
output shaft adjustment angle can be used. The lever arm on the actuator should have
nearly the same length as the throttle valve lever (between 25 and 40 mm). If a larger angle
at the carburettor is necessary for special applications, the lever arm may be lengthened.
For a linear displacement, e.g. injection pumps, the lever arm length is as follows:
L = 0,95 a
a = travel of the injection pump

The order specification is RH 1-01, with EDV No.: 501-80-032-00

11.3 Connecting Linkage

The connecting linkage from the governor to the injection pump or the carburettor should
be lengthwise adjustable. If possible, joint rod heads to DIN 648 should be used as con-
necting links. The linkage must operate easily and without clearance.
In case of friction or backlash in the linkage connecting the actuator and the injection
pump or throttle valve optimum control will not be possible.

11 Regulating Linkage

11.4 Linkage Adjustment for Diesel Engines

The E 1 and E 2 control systems can be installed on diesel engines with distributor injec-
tions pumps (such as Bosch, CAV, Lucas) or inline pumps up to 4 cylinders with RS me-
chanical regulators.
Older distributor injection pumps (produced before 1990 approx.) have a stop lever. In this
case, the linkage connecting the actuator must be attached to this stop lever.
More recent pumps have an electric magnetic valve for shutting the engine down. With
these pumps, it is only the speed adjustment lever that the linkage may be connected to.
This means that the mechanical control will still be active and receive just the setting value
from the electronic control.
On engines with inline pumps and RS mechanical controls the linkage must be connected
to the stop lever, and the internal spring provided to pull the stop lever into maximum posi-
tion must be removed.

11.5 Linkage Adjustment for Gas and Gasoline Engines

The throttle characteristic of gas engines and Otto engines is non-linear. This means that
within the zero load range but small changes of the throttle position will already result in
large changes of speed or load whereas with the throttle nearly fully open only larger
changes of the throttle position will lead to distinct changes of speed or load.
To obtain the best possible control performance across the entire operating range it will be
necessary to compensate for the non-linear behaviour of the throttle by means of a non-
linear linkage. In this case, the length of the linkage is adjusted in such a way that with the
control unit in full load position the throttle is completely open. The below figure shows
the correct assembly.

12.3 Connection of Power Supply

Inappropriate choice of power supply or insufficient battery capacitance or incorrect con-
nection of the power supply line or too small cable sizes of the feed line and the motor line
of the actuator are bound have an adverse effect upon the performance of the speed gover-
nor. In steady state operation, this will cause a heavy increase of current consumption and
unnecessary vibration of the actuator drive. The high current consumption will in its turn
lead to overheating of the actuator or the amplifier in the control unit, and the vibration
will result in premature wear of the gear and bearing parts or of the linkage.

In altogether, the lifetime of the control system is distinctly reduced by

the errors described above.

Figure 17: Correct Connection of Power Supply

If there are battery chargers with rapid charge mode installed in the
plant, the rapid charge mode should no be used during operation.
Warning

If there is no battery provided, it is absolutely necessary that a stabilized power supply

with at least 24 V DC, 10 Amps output power be used as a power source.

from 12 to 20 m 2 x 4,0 mm².

When power supply, battery and cabling have been correctly dimen-
sioned, then on starting the engine or with the actuator operating at
maximum current consumption (approx. 5 Amps), there may occur no

greater a drop of the supply voltage directly at the control unit than of
approx. 2 Volts maximum.

12.4 Connection of Shielding

Trouble-free operation of the electronic governor requires a shielding for important con-
nection lines.
The shielding has to be connected to minus potential of the control unit or the accessories
of the governor.
In this case the shielding has to be connected on one side only, the other side must not be
connected and there may not be any connection to ground.
Example: magnetic pickup for governors E 1-F and E 2-F

If a line with shielding is wired via a terminal strip, the shielding has to be connected to the
terminal strip without contact to a negative line or ground.

 12 Electrical Connection

To summarize, the following should be noted:

Shieldings of governor cables have to be connected to the control unit or the governor
asseccories (connected to the control unit via the 0 Volt line). The shielding may not any-
where else be connected with minus or ground.

12.5 Checking of Shielding

a) Remove the plugs from the control unit and check the shielding connections from the
cable plugs against ground. For the governors E 1-F and E 2-F these are the contacts 1
and 3. There may no connection be indicated.
b) With the plug screwed on, connect the other side of the shielding to the negative line
via the test instrument. The test instrument must indicate connection. If no negative
line is in the cable, then for testing purpose only, a connection with another line must
be established via a link in the cable socket.

14.2 Magnetic Pickup

Set the pickup distance to 0.5 to 0.8 mm from the highest point of the gear wheel (refer to
chapter 6.4). At cranking speed the voltage must be minimum 0.5 V AC or more.

14.3 Linkage
Mount the linkage between the actuator and the fuel system according to instructions (refer
to chapter 11). Check that there is no backlash in the linkage between actuator and fuel
system and that the linkage is moving freely and without friction.

14.4 Electrical Connections

Refer to connection diagrams in chapter 12.
Make cable connections between:
Control unit - magnetic pickup
- speed setpoint potentiometer (only with variable speed governor!)
- actuator
- battery
If the speed switch is used:
yellow cable of control unit - relay - battery ( - ); install freewheeling diode!
If start fuel limitation is used:
auxiliary contact of generator breaker (NC) or speed switch - battery
- green cable of control unit
There is no need for these connections if the speed switch or start fuel limitation are not
used.

14.5 Switching on Power Supply

The red LED below the hinged cover of the control unit lights up to indicate that voltage is
being applied to the control unit.

14.6 Engine Start

On starting the engine, you must be prepared to activate the emergency

shutdown.
Warning

34 Basic Systems E 1-F and E 2-F

 14 Adjustment of E 1-F and E 2-F Governors

The red LED will go out when cranking speed is higher than 50 rpm.
If the LED fails to go out, there is no signal from the magnetic pickup or the distance be-
tween pickup and fly wheel is too large.

14.7 Adjustment of Start Fuel Limitation

Start fuel limitation is active as long as battery voltage is applied to the green cable. To
make the adjustment it must be ensured that the engine is rotating but does not start run-
ning. During adjustment this is achieved with gas engines by turning ignition off and with
diesel engines by simultaneously activating the stop magnet. Use the start fuel potentiome-
ter to set the desired start fuel quantity.

Connect the test unit PG 01 to the control unit as shown in the figure. Then set the
switch from test unit to position 3. Turn the test unit off, then on again or carefully
move the regulating linkage. The test unit will now simulate the engine (refer to man-
ual E 83 008-e, Test Unit PG 01).

The engine must not be started during simulation, otherwise it can go

to over speed!
Warning

If there exists an external setpoint potentiometer turn it into its rightmost position
(right stop). Then use the internal multiturn potentiometer “Speed” of the control unit
to set the frequency associated with operating speed.
b) HEINZMANN has been informed of the number of teeth and the operating speed when
the order is placed. In this case, the control unit is set to the operating frequency speci-
fied by the customer before it leaves the factory. The operating frequency setting is in-
dicated on the name plate.
c) If HEINZMANN has not been informed of the desired operating frequency before the
control unit is shipped, the frequency is set to 4000 Hz. When commissioning the en-
gine then speed must be corrected if necessary by means of the internal multiturn po-
tentiometer.

If it is not possible to set the desired operating speed the jumper for determin-

Figure 25: Droop Potentiometer

Droop potentiometer counter clockwise to min. stop end reduces the droop to zero
(isochronous).
Droop potentiometer clockwise to max. stop end produces a droop of approx. 15 %
over the complete actuator angular travel range. If for example, 40 % of the angular travel
between zero load and full load is used, the max. droop is correspondingly smaller
( approx. 6 %).

To obtain satisfactory control results it will be necessary to utilize the largest

possible operating angle of the actuator. Droop is then set to the correct value
Note by means of the potentiometer.

14.12 Using of non Heinzmann synchronizers and load setting units

For this application the KG 1-08-F or KG 2-08-F with the synchronizer input is required.

Use an isolation amplifier to feed the steering signal into the

Heinzmann governor to prevent disturbances.

Warning

Adjustment procedure:

1. Start the GenSet to rated speed (e.g. 50 Hz) without connecting the external steering.
2. Measure the voltage on the synch. Input (brown cable) to 0.V (blue cable):
3. Adjust the offset voltage in the external steering exact to the measured level.
(There must not be a speed change if you connect the steering to the governor and the
synchronization is not active).
4. Turn Droop potentiometer 60 to 70% clockwise (results about 4% Droop, depending on the
used actuator travel, see Figure 26)
5. This adjusted Droop (4% = +/- 2 Hz at 50 Hz generator frequency) gives the operating
range for synchronization and load setting.
