No
Type
Description
It is always detected when the sensor is selected as fuel level sensor.
26
Flex. Sensor 1 Wrong
When voltage or current input is selected for the curve type of the
controller, and the controller detects input signal is abnormal, it shall
issue a warning, and meanwhile the curve is transferred to resistor type
to prevent damaging the controller.
It is detected always.
27
Flex. Sensor 2 Open
When the controller detects the sensor circuit is open, it shall issue a
warning.
It is always detected.
28
Flex. Sensor 2 High
When over high warning is enabled, and the controller detects the
sensor value is above the preset upper limit, it shall issue a warning.
It is detected after “safety on time” before “ETS solenoid hold” when the
sensor is selected as temperature sensor and pressure sensor;
It is always detected when the sensor is selected as fuel level sensor.
29
Flex. Sensor 2 Low
When over low warning is enabled, and the controller detects the
sensor value is below the preset low limit, it shall issue a warning.
It is detected after “safety on time” before “ETS solenoid hold” when the
sensor is selected as temperature sensor and pressure sensor;
It is always detected when the sensor is selected as fuel level sensor.
30
Fail to Stop
After ‘fail to stop delay’ is over, if the genset does not stop completely,
it will initiate a warning alarm.
It is detected when the genset is normally running.
31
Charge Alternator
Failure
When this is enabled and the controller detects that charger voltage is
below the pre-set limit, it will initiate a warning alarm.
It is detected when the genset is normally running.
32
Battery Over Volt
When this is enabled, and the controller detects the battery voltage is
above the preset limit, it shall issue a warning signal.
It is always detected.
33
Battery Under Volt
When this is enabled, and the controller detects the battery voltage is
below the preset limit, it shall issue a warning signal.
It is always detected.
34
Fail to Sync.
If the controller doesn’t detect sync. signal within the pre-set time, it will
initiate a warning alarm.
It is detected when GCB closes.
35
GOV Reach Limit
When the controller’s GOV output reaches the upper limit or lower limit,
it will initiate a warning alarm.
It is detected when the genset is running.
36
AVR Reach Limit
When the controller’s AVR output reaches the high limit or low limit, it
will initiate a warning alarm.
It is detected when the genset is running.
37
Gen Breaker Alarm
When “Gen Closed Aux” is not set for the controller input port, the
controller will initiate a warning alarm.
It is always detected.
