Breaker open and cool down (BOC)
The event appears in the Alarm list and is recorded into the history log. It causes immediate opening of the
GCB and then the standard stop sequence with cooling follows. The Gen-set cannot be started again while
there is a BOC alarm in the Alarm list. Activates the output
as well as the
standard alarm outputs (
and
).
IMPORTANT: In case there is no feedback from breakers configured Breaker open and cool down
will be replaced by shutdown alarm type.
Sensor failure detection (FLS)
If the measured resistance on an analog input exceeds the valid range, a sensor failure will be detected and a
sensor failure message will appear in the
. The valid range is defined by the far left (RL)
and far right (RH) points of the sensor characteristic ±12.5 % from RH-RL.
Note:
Sometimes there can be problem with lower limit of valid range which can be counted as negative
number. In this case the lower limit is set as one half of the RL point of the sensor curve characteristic.

Remote alarm messaging
If the communication plug-in module is connected to the controller, the controller can send SMS messages
(CM-RS232-485 module) and emails (CM2-4G-GPS or CM3-Ethernet modules) at the moment when a new
alarm appears in the
or new event is written in the
. The
message will contain a copy of the
or reasons from the
. To
enable this function first to check the controller internet connection (
Subgroup: TCP/IP Settings (page 354)
for CM3-Ethernet or
Subgroup: TCP/IP Settings (page 338)

to ON. Also enter a valid GSM phone number or email
address to the setpoints
