• When the Service LED is on, the load LEDs are turned into a fault indicator for as long as
the Alarm Off button is pushed and held down.
TIP: See Section 5.2 for more troubleshooting information.
Procedure:
When the Service LED is on, press and hold
1

have to restart the unit. For others, the fault
is cleared by pressing the Alarm Off button.
