Introduction
When an alarm condition occurs, the display buzzer starts. Pressing the alarm key displays the current
fault. Pressing the alarm key twice stops the buzzer while pressing it thrice removes the alarm.
Remark: Sometimes, when an alarm occurs, another spurious alarm of star/delta transition failure also
occurs. In this case, solve the spurious alarm first. If the spurious alarm occurs again, check the
electrical connections.
If the alarm is not removed even after pressing the alarm key again, it means that faulty conditions still
exist.
