CEM7 CONTROL UNIT INPUTS AND OUTPUTS | PAGE 31
PROGRAMMED OUTPUT FOR STARTING DUE TO LOAD DEMAND
DESCRIPTION
This functionality allows the activation of an output when the power generated by
the generator set exceeds a programmable threshold for power generated by the
genset.
PROGRAMMING
With the generator set in operation, an output programmed with the load demand
start function will be activated (Settings table, parameters 1-4) when it is
detected that power consumption exceeds a programmed parameter limit
(Thresholds table, parameter 34). The output will remain active until the genset
power consumption falls below a programmed parameter limit (Thresholds table,
parameter 35). Both with the activation and deactivation of the load demand
output, the conditions must be validated for a programmable time (Times table,
parameter 27).
PROGRAMMED OUTPUT FOR GENSET CONTACTOR STATE
DESCRIPTION
The programmable outputs can be congured to monitor both the genset breaker
condition and the network breaker condition (CEM7P control unit only).
WATCHDOG PROGRAMMED OUTPUT
DESCRIPTION
The programmable outputs can be congured to monitor the status of the
electronics. The output remains active if the correct operation of the generator
set's control system is veried.
STABILIZED ENGINE PROGRAMMED OUTPUT
DESCRIPTION
Programmable outputs can be congured to monitor the stabilized engine status
(Settings table, parameters 1 to 4 or 24, value 96). The output remains active
once it detects the stabilized running condition of the engine after start-up (Times
table, parameter 7) including the cooling time during the stopping cycle.
NOTE:
Activation of the genset contactor is performed with a programmable time after
detecting that the engine is in operation (Times table, parameter 6), it being
possible to dephase the activation of the genset contactor and programmed
output in STABILIZED ENGINE mode.
PROGRAMMED GENSET CONTACTOR OPENING OUTPUT
DESCRIPTION
Programmable outputs can be congured to open the genset contactor for use
with motorized thermal-magnetic circuit breakers (Settings table, parameter 1 to
4, value 27). The output can be congured so that it is activated continuously or
in a timed mode via a pulse (Times table, parameter 29).
PROGRAMMED FUMES CONTROL OUTPUT
DESCRIPTION
Programmable outputs can be congured to initiate the engine start-up process
with fumes control. This requires assigning a programmable output (Settings
table, parameters 1 to 4, value 97) that will be enabled during the start-up
process and will remain active for a programmable length of time (Times table,
parameter 33) once the engine is running.
