Charge corona output error
D
The feedback voltage from the charge corona unit is detected too high 9
times.
300
-
Charge corona power pack defective
Charge corona harness disconnected
Poor charge corona unit connection
Charge corona grid leak
D
When the high voltage is output to the corona grid, feedback voltage
exceeds the prescribed value 9 times.
303
-
Charge corona power pack defective
Charge corona harness disconnected
Poor charge corona unit connection
Charge grid circuit open
304
D
When high voltage goes to the corona grid, feedback voltage is more than
the set value 9 times. This feedback voltage is used to update PWM for
output control.
