Type
Description
It is always detected.
28
Oil Pressure Low
When this is enabled, and the controller detects the pressure is below
the preset limit, it shall issue an alarm signal.
It is detected after “safety on time” before “ETS solenoid hold”.
29
Oil Pressure Sensor
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.
30
Fuel Level Sensor Open
When the controller detects the sensor circuit is open, it shall issue an
alarm signal.
It is always detected.
31
Fuel Level Low
When this is enabled, and the controller detects the level is below the
preset limit, it shall issue an alarm signal.
It is always detected.
32
Flex. Sensor 1 Open
When the controller detects the sensor circuit is open, it shall issue an
alarm signal.
It is always detected.
33
Flex. Sensor 1 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.
34
Flex. Sensor 1 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.
35
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.
36
Flex. Sensor 2 Open
When the controller detects the sensor circuit is open, it shall issue an
alarm signal.
It is always detected.
37
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.
38
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.
