13 Mains circuit breaker (MCB) not closed
Icon:
Type:
Warning
Category:
General, loads protection
Related parameters:
P.2001
Function of input T.16 or equivalent for other inputs
P.2002
Delay for input T.16 or equivalent for other inputs
To disable:
P.2002=0
Enabled in:
MAN,
AUTO, TEST, REMOTE START
This protection is enabled only when one of the digital inputs of the controller is configured to
acquire the MCB status (feature DIF.3002 -
“MCB breaker status” in parameter P.2001 or
equivalent for the other inputs) and if a time other than zero has been set for said input
(parameter P.2002 or equivalent). It activates only when MCB is commanded to close and the
status acquired is continuously “not active” (open) for the time set.
14 Genset circuit breaker (GCB) not closed
Icon:
Type:
Deactivation/Warning
Category:
General
Related parameters:
P.2001
Function of input T.16 or equivalent for other inputs
P.2002
Delay for input T.16 or equivalent for other inputs
To disable:
P.2002=0
Enabled in:
MAN,
AUTO, TEST, REMOTE START
This protection is enabled only when one of the digital inputs of the controller is configured to
acquire the MCB status (feature DIF.3001 -
“MCB breaker status” in parameter P.2001 or
equivalent for the other inputs) and if a time other than zero has been set for said input
(parameter P.2002 or equivalent). It activates only when GCB is commanded to close and the
status acquired is continuously “not active” (open) for the time set.
It only operates as warning,
no automatic change-over to the mains is provided.
16 Short circuit on the generator
Icon:
Type:
Configurable (Block/Deactivation)
Category:
Generator protection
Related parameters:
P.0101
Number of generator phases
P.0102
Generator rated voltage
P.0106
Generator rated power
P.0311
Threshold for short circuit
P.0312
Delay for short circuit
P.0323
Action for maximum current and short circuit
To disable:
P.0312=0
Enabled in:
MAN, AUTO, TEST, REMOTE START
In addition to the maximum current protection, the controller also provides a short circuit
protection for quick intervention independently of timing for the maximum current protection
curve. Protection is given by setting a threshold (P.0311) expressed as a percentage of the
system rated current (see maximum current protection to calculate rated current with
parameters P.0101, P.0102 and P.0106). It is only enabled if the controller has been started
