alarm signal.
It is always detected.
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.
When over low alarm is enabled, and the controller detects the sensor
value is below the preset lower 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.
When this is enabled and the controller detects that the generator
power factor has fallen below the pre-set limit, it will initiate an alarm
signal.
It is always detected.
When this is enabled and the controller detects that the THD has
exceeded the pre-set limit, it will initiate an alarm signal.
It is always detected.
When this is enabled and the controller detects that the voltage
unbalanced value has exceeded the pre-set limit, it will initiate an alarm
signal.
It is always detected.
When controller detects that ground relay close failure, that is, breaker
close input is inactive after ground relay close outputs, and then it will
initiate an alarm signal.
It is detected when ground relay is closing.
When controller detects that ground relay open failure, that is, breaker
open input is inactive after ground relay open outputs, and then it will
initiate an alarm signal.
It is detected when ground relay is opening.
