The G3PW Power Controller has two alarm contact outputs: Alarm output 1
(ALARM1) and alarm output 2 (ALARM2).
For the following alarms, the contacts to which to output an alarm when an
error occurs can be selected with a parameter setting in the initial setting
level.
Alarm level
No alarm
Alarm level 1
Alarm level 2
Note Errors will not be detected if no alarm output is assigned.
• Heater burnout alarm (E40)
• External input range alarm (external variable resistor disconnection
detection) (E50)
• External duty input alarm (external variable resistor disconnection detec-
tion) (E51)
• Total run time exceeded alarm (E60)
(1) If multiple errors occur, the most recent error will be displayed on the 7-
segment display. (For details on error numbers, refer to 7-2 Error Dis-
plays.)
(2) Errors other than the above are set to alarm level 1 and cannot be
changed.
