10 - 6 IM 4H3B1-01E
Alarm Indication When ALARM ACK-key is Pressed:
Non-Hold type: Alarm display is not affected when the ALARM ACK-key is
pressed.
Hold type: When alarm occurs, alarm indicator will start flashing. After
pressing the ALARM ACK-key, the indicator will show the status
of the alarm.
PERFORMANCE and CHARACTERISTICS
