7. CEC7 CONTROL UNIT ALARMS
The CEC7 control unit has a list of alarms, the operation of which can be congured
so that actions are performed or so that they are shown on the display module
screen.
The CEC7 control unit, working with a generator set control unit from the CEM7
family, integrates the generator set alarms in its operation, allowing the
management of genset and switching alarms from any screen connected to the
system.
The CEC7 control unit distinguishes between errors that cause the stopping of the
engine (alarms with generator set stop), deactivation of the genset contactor
(installation power interruption alarms) and errors that do not cause stopping of
the engine (warnings).
Upon detection of an alarm or warning, the control unit produces an acoustic
signal, which activates the alarm digital output (AL) and the LED of the RESET
button and the display screen ashes. This condition will remain as long as the
error condition continues for a programmable maximum period of time (Times
table, parameter 14).
When there is an alarm, active warning or pending notication, the LED of the
RESET button remains illuminated. Pressing the RESET button allows the user to
view a list of alarms, active warnings and pending notication. To scroll through the
list of errors use the buttons on the display
. A second press of the RESET
button allows notication of the alarm which disappears from the list of active
alarms if the condition that caused it is no longer present.
The alarms related to the network signal cause the ashing of the LED associated
with the network signal condition .
The alarms related to the genset signal cause the ashing of the LED associated
with the genset signal condition
.
