CEA7 CONTROL UNIT ALARMS | PAGE 41
PROGRAMMABLE ALARM 1
The CEA7 control unit's programmable alarm 1 is activated associating the
operating mode of the programmable alarms (Settings table, parameter 13) to
one of the general purpose digital inputs (ENT1, ENT2, ENT3, ENT4 or ENT5) or
one of the engine alarm inputs (ATA, BPA or NA) in the J1939 option. The status
of this input must be validated during a time interval (Times table, parameter 19,
20, 22, 23 or 24) for stabilisation (debounce) before generating programmable
alarm 1. Detection of the programmable alarm 1 is set by default (Alarms table,
parameter 79) to be activated: Never.
Programmable alarm 1 can be associated with a time (Alarms table, parameter
80) to delay the moment at which the alarm begins to conrm the alarm
conditions. Programmable alarm 1 is set by default (Alarms table, parameter 81)
to perform no action (warning). Programmable alarm 1 can be associated with a
programmable text that appears on the display of the display module when the
active alarm is detected.
PROGRAMMABLE ALARM 2
The CEA7 control unit's programmable alarm 2 is activated associating the
operating mode of the programmable alarms (Settings table, parameter 14) to
one of the general purpose digital inputs (ENT1, ENT2, ENT3, ENT4 or ENT5) or
one of the engine alarm inputs (ATA, BPA or NA) in the J1939 option. The status
of this input must be validated during a time interval (Times table, parameter 19,
20, 22, 23 or 24) for stabilisation (debounce) before generating programmable
alarm 2.
Detection of the programmable alarm 2 is set by default (Alarms table, parameter
82) to be activated: Never.
Programmable alarm 2 can be associated with a time (Alarms table, parameter
83) to delay the moment at which the alarm begins to conrm the alarm
conditions. Programmable alarm 2 is set by default (Alarms table, parameter 84)
to perform no action (warning). Programmable alarm 2 can be associated with a
programmable text that appears on the display of the display module when the
active alarm is detected.
LOW ENGINE TEMPERATURE
The CEA7 control unit's low engine temperature alarm is associated with the
analogue input for the water temperature (T). The low engine temperature alarm
is activated when a lower temperature is detected than the programmed limit
(Thresholds table, parameter 28).
Detection of the low engine temperature alarm is set by default (Alarms table,
parameter 73) to be activated: Never.
A low engine temperature alarm can be associated a debounce time (Alarms
table, parameter 74) during which it must be detected that the engine
temperature is below the limit set (Thresholds table, parameter 28).
The low engine temperature alarm is set by default (Alarms table, parameter 75)
to perform no action (warning).
Activation of the contactor group (CG) is limited if the low engine temperature
threshold has been programmed (Table thresholds, parameter 28) with a value
other than zero and the engine coolant temperature measured is below this set
threshold.
GENSET SIGNAL FAILURE
The CEA7 control unit's genset failure signal alarm is generated if no genset
voltage is detected during any phase while the engine is running.
Detection of the genset failure signal alarm is set by default (Alarms table,
parameter 76) to be activated under nominal engine conditions.
A genset failure signal alarm can be associated a debounce time (Alarms table,
parameter 77) during which no signal must be detected during any phase before
activating the alarm.
The genset failure signal alarm is set by default (Alarms table, parameter 78) to
always perform a stop of the engine with cooling.
