Delay Description
DIF.0000 Not used.
Input not used.
DIF.1001 GCB closing command
It only acts in MAN and TEST modes, used to control the
manual closing of the GCB circuit breaker. If there is no
input configured with the function DIF.1002, this input
works in reality as toggle: it commands the closure of the
breaker when the same is open and commands the
opening when the same is closed.
DIF.1002 GCB opening
command.
It only acts in MAN and TEST modes, used to control the
manual opening of the GCB circuit breaker.
DIF.1031 MCB closing
command.
Only acts in MAN and in TEST, used to control the
manual closure of the MCB breaker. If there is no input
configured with the function DIF.1032, this input works in
reality as toggle: it commands the closure of the breaker
when the same is open and commands the opening
when the same is closed.
DIF.1032 MCB opening
command.
Only acts in MAN and in TEST, used to control the
manual opening of the MCB breaker.
DIF.2001 Alarm reset command.
When the input becomes active, the controller executes
a reset of all anomalies. That is equivalent to change the
controller mode to OFF/RESET and back again to the
desired mode.
DIF.2031 TEST mode command.
When the input is “active”, the mode of the controller
switches from AUTO to TEST (the input does nothing if
the controller is not in AUTO or if the automatic
intervention of the genset is required). When it becomes
inactive, the status changes back to AUTO.
DIF.2032 REMOTE START
command.
Yes
If the input is “active”, the controller operating mode
changes from AUTO to REMOTE START (the input does
nothing if the controller is in OFF/RESET or MAN mode).
When it becomes inactive, the status changes back to
AUTO.
DIF.2033 Manual start request.
When the input
“activates” (only in MAN mode), the
controller tries to start (only once) in the same way of an
automatic start, that is commanding the motor up to the
start success or failure.
DIF.2034 Manual stop request.
When the input activates (in MAN mode), the controller
commands the stop of the engine. It equals to pressing
the STOP button.
DIF.2041 Request of load taken
in manual
When the inputs activates (only in manual mode) the
opening of MCB and the closing of GCB are required,
and vice versa when it deactivates.
DIF.2071 Inhibit DPF
regeneration.
When the input is "active", the controller "prevents" the
regeneration of the particulate filter to the engine ECU.
See par. 7.4.8.12.
DIF.2072 Force DPF
regeneration.
When the input is "active", the controller requires the
regeneration of the particulate filter to the engine ECU.
See par. 7.4.8.12.
DIF.2151 Select configuration 1.
When the input becomes"active", parameters of
alternative configuration set 1 are copied in the working
configuration.
DIF.2152 Select configuration 2.
When the input becomes"active", parameters of
alternative configuration set 2 are copied in the working
configuration.
