Digital Governor Basic System PANDAROS III
h) Speed dependent quantity limitation
It is possible to programme quantity limitation curves in dependence of speed so that for
all speeds there can be torque reduction as is admissible for the engine or desired by the
user.
i) Temperature dependent idling speed and quantity limitation
At 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. It is possible to programme
quantity limitation curves in dependence of temperature so that for every temperature
there will be torque reduction available as is admissible for the engine or desired by the
user.
j) Operating hour meter
The operating hours when the engine is turning (speed is detected) will be added.
k) Failure diagnosis and display
If a sensor or the actuator is at fault, an alarm is issued and there will be a change-over
to emergency operation if so provided or an engine shutdown. Internal errors get
detected also and they will be stored as all other failures. All failures can be read out
with an external handprogrammer or with a communication program on a PC or laptop
with communication cable.
l)
Communication
Two serial interface ports are available: ISO 9141 and RS-232.
3.2
Variation specific additional functions
3.2.1
Variation DC 6-01 (standard generator)
(refer to connection diagram page 31)
The setpoint is realized with two push buttons: increase speed and decrease speed.
3.2.2
Variation DC 6-02 (standard general)
(refer to connection diagram page 32)
The setpoint is given by an analogue setpoint source (voltage source 0..5 V, current
4..20 mA or potentiometer 5 k ) and one switch input for fixed speed.
