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 an alarm signal, 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 an
alarm signal.
It is always detected.
28
Flex. Sensor 2 High
When over high alarm is enabled, and the controller detects the sensor
value is above the preset upper limit, it shall issue an alarm signal.
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 alarm is enabled, and the controller detects the sensor
value is below the preset low limit, it shall issue an alarm signal.
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
Charge Alternator
Failure
When this is enabled, and the controller detects the charger voltage
value is below the preset limit, it shall issue an alarm signal.
It is detected when the genset is normally running.
31
Battery Over Volt
When this is enabled, and the controller detects the battery voltage is
above the preset limit, it shall issue an alarm signal.
It is always detected.
32
Battery Under Volt
When this is enabled, and the controller detects the battery voltage is
below the preset limit, it shall issue an alarm signal.
It is always detected.
33
Fail to Sync.
If the controller doesn’t detect sync. signal within the pre-set time, it will
initiate an alarm signal.
It is detected when GCB closes.
34
Volt Asynchrony
After GCB is closed, the voltage difference between busbar and
generator is above the preset synchronous voltage, the controller shall
issue an alarm signal.
It is detected after GCB is closed.
35
Freq Asynchrony
After GCB is closed, the frequency difference between busbar and
generator is above the preset synchronous frequency, the controller
shall issue an alarm signal.
It is detected after GCB is closed.
36
Phase Asynchrony
After GCB is closed, the voltage phase difference between busbar and
generator is above the preset synchronous phase, the controller shall
issue an alarm signal.
It is detected after GCB is closed.
