2 General Remarks

2 General Remarks
HEINZMANN digital governors with control units DC 64.1 - 03 or DC 90.1 - 03 constitute
speed governors offering a wide range of functions.
In addition to speed regulation, the following functions are available:

a) Starting Fuel Flow Adjustment

When setting starting fuel flow, starting minimum fuel flow or starting maximum fuel flow
are available as alternatives. If nesessary, both als can be depent on temperature. Furthermore,
variable starting fuel flow can be provided, by which starting fuel flow is increased
automatically during start-up.

b) Speed Ramp
For applications in which speed is not supposed to respond as fast as possible to changes of
setpoint values (e.g., locomotive operation), a speed ramp is available which according to
requirements may be programmed separately for increasing or decreasing speed.

c) Fixed Fuel Limitation

For the stop-position and the maximum fuelling position "electric catches" can be provided.
This will prevent the governor's thrust from affecting the terminal stops of the injection pump,
etc.

d) Speed Dependent Fuel Limitation

For variable speed governors, there is provided an option of programming speed dependent
limit curves. Thus, for any speed, torque can be reduced as is permissible for the engine or
desired by the user.

e) Boost Pressure Dependent Fuel Limitation

For turbocharged engines, fuelling can be reduced to achieve smokeless operation in case of
missing boost pressure (e.g., starting or load change). The respective limit curves can be
programmed accordingly.

f) Idling and Maximum Speed Control

For vehicle application, the governor can be made to operate as an idling and maximum speed
controller. In addition, one fixed intermediate speed is available, e.g., for an application
combining driving and stationary mode (e.g., generator at power take-off). If necessary, a
4 PRIAMOS II
 2 General Remarks

change-over switching of the droop can be provided, i.e., during stationary operation also
droop zero is possible

g) Temperature Dependent Idling Speed

For low temperatures, the engine can be run at some higher idling speed. With the engine
warming up, idling speed is reduced to its normal value.

h) Oil Pressure Monitoring

For the purpose of oil pressure monitoring, speed/pressure dependent limit curves can be
provided. If oil pressure is too low, an alarm is given; if oil pressure continues to drop, the
engine is shut down.

i) Load Regulation System

For diesel-electric locomotive operation, a load regulation system can be provided, by which
generator output is regulated in dependence on speed resp. load.

j) Anti Stick Slip Device

For locomotive operation, an anti stick slip device can be provided.

k) Accessories
Accessories such as synchronizing units, load measuring units, disturbance variable
compensation units can be connected via a CAN-Bus within the control unit. The CAN-Bus
may also be used to implement load distribution by equal fuelling (e.g., two engines on one
gear).

l) Output Signals
For speed and actuator travel, proportional signals are available in the range of
4–20 mA. They can be used for purposes of display or for further processing (e.g., switches).

m) Operating Data Storage

On request, operating data storage can be provided, by which in cases of disturbances and
failures the causes may be traced back even at some later time.

Furthermore, if errors occur at the sensors or within the control system, an alarm is given.
PRIAMOS II 5
2 General Remarks

When selecting and determining the functions, it has to be ascertained whether

the hardware equipment suffices with respect to the total range of functions.
Note

6 PRIAMOS II
 3 Mode of Operation

3 Mode of Operation
The actual speed of the engine is read by a pulse pickup from a cog wheel, preferably from
the starter gear. The microprocessor (CPU) of the control unit compares the actual speed with
the preset value. If differences are stated, the new actuator signal is calculated by the CPU and
transmitted to the actuator via the output stage. Feedback from the actuator indicates the
current position of the output shaft thus allowing optimum signal adjustment by the CPU.
As the governor comprises an I-fraction and as for any load level the speed is permanently
compared with a fixed preset value, speed can be kept constant also in steady state, i.e., droop
is zero.
For applications requiring droop, the speed related to the respective fuelling is calculated by
the CPU and entered as correction of the setpoint value.
During standstill, a particular circuit ensures that only the current of the control unit is
received by the governor, but no current flows to the actuator motor.

5.2.2 Installation
The installation of the pickup has to be arranged in such a way as to obtain a frequency
as high as possible. Normally, the HEINZMANN digital governors DG 64.1 - 03 and
DG 90.1 - 03 are designed for a maximum frequency of 6.000 Hz. The frequency (by
Hz) is calculated according to the formula:

f (Hz) =

z = number of teeth on the pickup wheel

Example:
n = 500
z = 80

f = = 666.67 Hz

It should be taken care that the speed can be measured by the pulse pickup without any
bias. For best results therefore, the speed pickup should take the 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).

10 PRIAMOS II
 5 Sensors

5.2.3 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 (8 mm at IA 22 - 76 and IA 23 - 102).
For index plates the same dimensions are valid.
Due to tolerances, a radial arrangement of the magnetic pickup is preferable.

5.2.4 Clearance for IA 02 - 76 up to IA 13 - 102

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 in the magnetic pickup till it touches the tooth and
then unscrew it for about half a turn.)

5.2.5 Clearance for IA 22 - 76 and IA 23 - 102

The distance between the magnetic pulse pickup and the tooth top should range from
2.5 to 3 mm. (It is possible to screw in the magnetic pickup till it touches the tooth and
then unscrew it for about two turns.)

5.2.7 Redundant Speed Signal

If precautions are to be taken with regard to failures od the pulse pickup, a second pulse
pickup can be connected to the control unit. In case that an electric generator with
terminal W is available, this signal may be used for emergency operation as well as any
other signal of a tachogenerator.
In case of a failure on puls pickup 1, the governor automatically switches over to the
redundant speed signal and gives an alarm.

On request, the potentiometers, as specified under 6.1 and 6.2, 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 installed. Ordering specification is
to changed to SW ..-..-k.

6.3 Setpoint Value Adjustment by Current Signal

For the speed setpoint value a current signal of 4–20 mA can be directly connected to the
control unit. If the signal fails, the governor will set minimum speed according to the 4 mA
value or a programmable substitute value.

6.4 Digital Presetting of Setpoint Values

A 4 bit binary coded digital input for 16 speed levels from nmin to nmax can be directly
connected to the control unit.

6.5 Setpoint Value Adjustment by Pedal

This unit is basically an angular position transducer that translates a foot pedal into a
proportional current or voltage for 0 - 45° rotation. The resulting output can be used for
speed setting. For more information refer broschure E 83 005 - e.

6.6 Pneumatic Setpoint Adjusters

8.1 Design and Mode of Operation

governor output shaft feedback probe

feedback cam

gearbox

dc disk armature
motor

Figure 11: Sectional Drawing of Actuator

The actuator torque is generated by a DC disk armature motor and transmitted to the
governor output shaft by way of a gearbox.
The use of special materials and long-time lubricants assures maintenance-free operation
and long working life of the actuators.
A feedback cam is mounted on the governor output shaft which is scanned contactlessly by
a probe, thus transmitting the precise position of the output shaft to the control unit.
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
cannot harm the motor.

PRIAMOS II 21
8 Actuators

The actuators StG 64 - 01 and StG 90 - 01 are identical in their design. The higher torque
of the actuator StG 90 - 01 is produced by a different solenoid system.
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
consumption on change of load.
- Indifference to slow voltage changes of the supply; abrupt voltage changes cause
governor disturbances.

8.2 Installation
The actuator must be mounted firmly on the engine by means of reinforced brackets.
Unstable 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!

 9 Regulating Linkage

9 Regulating Linkage

9.1 Length of Regulating Rack

The length of the regulating rack is determined in such a way that approx. 90 % of the
governor output shaft adjustment angle can be used. Based on this, the rack length L of
governors with 42° adjustment angle is calculated as L = 1.5 a, "a" being the travel
distance of the injection pump or the carburettor.

9.2 Connecting Linkage

The connecting linkage from the governor to the injection pump or the carburettor should
be length-adjustable and have a (pressure or tension) elastic link. If possible, joint rod
heads in accordance with DIN 648 should be used as connecting links. The linkage must
operate easily and without clearance.
In case of friction or backlash in the linkage connecting actuator and injection pump resp.
throttle valve no optimal control is possible.

PRIAMOS II 25
9 Regulating Linkage

9.3 Linkage Adjustment for Diesel Engines

The length of the connecting linkage is adjusted in such a way that with the governor in
stop position the injection pump is set to 0 - 2 fuel marks. (Travel of the injection pump
control rack is limited by the governor.)

9.4 Linkage Adjustment for Carburettor Engines

For carburettor or gas engines, the length of the connecting linkage is adjusted in such a
way that with the governor in full load position the throttle valve is completely open. In
idling speed position, the elastic link must be slightly overcome. This allows adjustment of
the idle screw without changing the governor adjustment.

10 Electric Connection

10.1 Connection of Shielding

To avoid elektromagnetic influences it is necessary to connect cable shields at both ends.
This includes shielding from control housing to sensors, from control housing to
potentiometers, from control housing to actuator and from control housing to accessory
units. If there is a potential difference between the control housing and any of these other
componets, to avoid currents via the shielding it is necessary to run a separate wire from
the control housing to each of these components.

10.2 Connection of Power Supply

Inappropriate choice of power supply or insufficient battery capacitance or incorrect
connection 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
governor. 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.

The cable sizes and cable lengths described in the wiring diagrams
must not be exceeded!
Warning

When power supply, battery and cabling have been correctly dimensioned, then on starting
the engine or with the actuator operating at maximum current consumption (approx. 6.4
Amps), a drop of the supply voltage directly at the control unit of approx. 2 Volts
maximum only will be admissible.

12 Programming Possibilities

12 Programming Possibilities
Programming the HEINZMANN Digital Governor can be performed according to the
possibilities described below:

12.1 Programming by the Manufacturer

During final inspection by the manufacturer, the functionability of the governor is checked
by means of a test program. If the operational data for the governor are available, the test
program is executed using those data. On the engine, only the dynamic values and, if
necessary, the actuator position limits and sensors have to be adjusted.

12.2 Programming with the Hand- Held Programmer 2

The entire programming can be performed using the Hand-Held Programmer 2. This handy
device may be conveniently used for development and for serial adjustment as well as for
service purposes.

12.3 Programming by PC
Programming can also be performed using the PC. In comparison with the hand-held
programmer, this method offers advantages with respect to the possibilities of having
characteristic curves readily displayed on the screen and easily varied; the same holds for
the time diagrams when putting the governor into operation on the engine. Furthermore,
the PC offers a better overview, as the PC program presents a menu structure and is able to
continuously display several parameters at a time.
The PC program also permits to save and load governor data to and from diskettes.

12.4 Programming with User Masks

Principally, programming may be performed with the help of user masks that have been
provided by HEINZMANN or may conveniently be created by the user himself. Within a
user mask, only those parameters are accessible that are actually needed.

12.5 Transferring Data Sets

Once programming with respect to a specific engine type and its application has been
completed, the data set can be stored (in the hand-held programmer or on diskette). For
future cases of similar applications, the data set may be downloaded into the new
governors.

34 PRIAMOS II
 12 Programming Possibilities

12.6 Assembly Line End Programming

This method of programming is applied by the engine manufacturer during the final bench
tests of the engine. On this occasion, the governor is programmed with regard to operation
requirements and to ordering specifications.

PRIAMOS II 35
13 Starting the Engine - Brief Instructions

13 Starting the Engine - Brief Instructions

13.1 Adjust clearance of magnetic pulse pickup.
13.2 Check program with respect to relevant parameters: number of teeth, speed, etc.
13.3 Set point potentiometer in mid-position:
P- Gain to 50
I- Stability to 0
D- Derivative to 0
If the dynamic values have already been determined for an installation, they can be
programmed directly at this point.

Overspeed protection must be guaranteed!

Warning

13.4 Start engine and run it up to nominal speed using the set point potentiometer.
13.5 Increase gain (P-fraction) up to instability and reduce until stability is attained.
Increase stability (I-fraction) up to instability and reduce until stability is attained.
Increse derivative (D-fraction) up to instability and reduce until stability is attained.
With these values set, engine speed is to be disturbed briefly (e.g., by shortly pressing
the stop switch), and the transient oscillations are to be observed.
13.6 Check over the entire speed range.
If for maximum and minimum speed other values than the programmed ones should
result, this will be due to tolerances of the set point potentiometer. If the speed
derivation is not acceptable, it will be necessary to measure the setpoint source.
13.7 Gain-correction (P-correction) for gas engines resp. for variable speed governors with
larger speed ranges; adjust map if necessary.
13.8 Checking the remaining program items, e.g., starting fuel injection, ramp time, etc.

The adjustment procedures as required for items 13.2 bis 13.8 and any further
options of adjustemnt are in detail described in brochure DG 95110 - e.
