EVT.1054: TEST mode requested by digital input.
EVT.1055: Command for stop in TEST mode from digital input.
EVT.1056: Command for start in TEST mode from serial port
EVT.1057: Command for stop in TEST mode from serial port
EVT.1058: TEST mode requested by clock/calendar.
EVT.1059: Command for stop in TEST mode from clock/calendar

In addition, the controller makes available the requests start/stop and the engine statuses for
the AND/OR logics by means of the following internal statuses:
ST.032 -
"Engine running”.
ST.033 -
"Oil protections enabled”
ST.035 -
"Engine sequence: standby”
ST.036- "Engine sequence: sta
rting”
ST.038 -
"Engine sequence: delay before power delivery”
ST.039 -
"Engine sequence: ready for power delivery”
ST.040-
"Engine sequence: cooling”
ST.041-
"Engine sequence: arrest”
ST.096 -
"Ready for power delivery”

Circuit breakers command.
Four different commands are available for the
MCB
circuit breaker management,
configurable on one or more digital outputs (see par. 5.6)
DOF.2001 -
“MCB (NC) Under voltage coil”.
This feature can be used to
supply the minimum voltage coil (if any) of the circuit breaker. The controller enables
this output when it must open the breaker, and disables it when it must close the
breaker: the real closing command will be activated with at least 0.5 seconds after the
disabling of this output.
It is therefore necessary to use a contact which is
normally
closed
, so that when the controller is not supplied, the under voltage coil is enabled
and the breaker can be closed.
DOF.2002 -
“MCB opening coil”. The controller enables this output when it wants to
open the circuit breaker: the output goes back in standby once the circuit breaker
feedback indicates that it is open (or when the opening time-out expires).
DOF.2003 -
“MCB closing coil”. The controller enables this output when it wants to
close the circuit breaker (ensuring that the function DOF.2001 has been active for at
least 0.5 seconds): the output goes back in standby once the circuit breaker indicates
that it is closed (or when the closing time-out expires, or the synchronism condition no
longer exists).
DOF.2004 -
“Commands of steady MCB opening”. The controller disables this output
to open the circuit breaker (guaranteeing that the possible function DOF.2001 is active
from at least 0.5 seconds): the output remains active even with open circuit breaker.
The controller disables this output to close the circuit breaker: the output remains
