4.6.4 Clearing latched alarms
4. OPERATION
The fault and alarm relays may be set to be latched (see CongurationMenu). So when an alarm
message is displayed on the LCD screen it may continue to be displayed even when the fault
causing the problem is corrected.
Note: Alarms may not be set to be latched, but because alarm recovery is set 25% below alarm
setpoint it could appear that they are for a short while.
