g)
Manual/automatic mode
It is possible to switch between manual and automatic mode.
h)
Generator switch
In order to make quicker adjustments when opening the power generator switch, it is
possible to activate a special function that queries the status of the power generator
switch. This status can be assigned to a digital input.
i)
Deleting errors
The current errors can be deleted by pressing an assigned button at a digital input.
j)
Automatic calibration of the actuator
After replacing the control device or the actuator, the feedback of the actuator can be
recalibrated by pressing an assigned button (actuator and control device are adjusted
in line with one another).

(refer to connection diagram DC 6-05)
a) Speed setpoint
The speed 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.
b) Boost pressure sensor
An analogue input is already specified for use with a boost pressure sensor. The input
can be configured for a 0 … 5 V or 4 … 20 mA signal.
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.
c) Oil pressure sensor
An analogue input is already specified for use with an oil pressure sensor. The input
can be configured for a 0 … 5 V or 4 … 20 mA signal.
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.
d) Idle-/Maximum speed governor
The governor may also be adjusted as an idle/max speed governor.
