3.2.3
Variation DC 6-03 (extended generator 1)
(refer to connection diagram page 33)
The speed setpoint is realized with two switch inputs to increase speed and decrease
speed each.
The
HEINZMANN
load measuring unit is connected to an additional analogue input
for load governing in parallel operation.
An additional switch input it to select if the switch inputs for synchronization or the
analogue input from the load measuring unit is active.
3.2.4
Variation DC 6-04 (extended generator 2)
(refer to connection diagram page 34)
The setpoint is given by an analogue setpoint source (voltage source 0..5 V, current
4..20 mA or potentiometer 5k ).
Two additional analogue inputs are used for connecting the
HEINZMANN
load
measuring unit for load governing in parallel mode and for connecting the
HEINZMANN
synchronizer.
A switch input is to select if the inputs of the
HEINZMANN
units or if the analogue
setpoint source is active.
3.2.5
Variation DC 6-05 (extended general, especially vehicle)
(refer to connection diagram page 35)
The setpoint is given by an analogue setpoint source (voltage source 0..5 V, current
4..20 mA or potentiometer 5k ) and a switch input for fixed speed.
For turbocharged engines, fuelling can be reduced to achieve smokeless operation
whenever there is no boost pressure (e.g., during start-up or on load changes). The
respective limit curves can be programmed accordingly.
For the purpose of oil pressure monitoring, speed/pressure dependent limit curves can
be provided. If oil pressure is low, an alarm is issued; if oil pressure continues to drop,
the engine is shut down.
The governor may also be adjusted as an idle/max speed governor.
