area on the display panel to notify the operator of an alarm. When more than one alarm occurs, it changes
an alarm display every second.
After confirming the contents of the alarm, press the [ALARM ACK] key on the operation panel or
left-click the alarm acknowledge-button on the display panel to acknowledge the alarm. When confirming
an alarm, the buzzer sound stops and the alarm display disappears from the alarm acknowledge-button.
However, until the cause of the alarm is removed, in the alarm display area, the alarm maintains a
displayed condition.
