Clearing and resetting a fault
Note
Fault Indication
If an alarm condition occurs before or during a fault condition, the LED and display will not
indicate the presence of an alarm until the fault condition is cleared and reset. Alarm conditions
are recorded in the alarm/fault log.
A fault signals system malfunction with the output of the drive disabled.
Clear and reset a fault condition immediately to ensure proper system function.
When a fault condition occurs, the fault indicator is red.
Perform the following steps to reset the system:
1. Check the display or the alarm/fault log to determine the cause of the fault.
2. Correct conditions that may have caused the fault.
3. Press the [FAULT RESET] key on the keypad to reset the system.
Clearing and resetting an alarm
When there are no fault conditions but an alarm condition occurs, the fault indicator will flash
red. Perform the following steps to acknowledge the alarm condition:
1. Check the display or the alarm/fault log to determine the cause of the alarm.
2. Correct conditions that may have caused the alarm.
3. Press the [FAULT RESET] key on the keypad to acknowledge the alarm.
Acknowledging an alarm will cause all alarms to no longer be displayed on the keypad
display. However, if any alarm condition still exists, the fault LED will flash red.
