3.4 Troubleshooting With the SID
The SID’s Output Load LEDs have two functions:
• When the unit is operating normally, it serves to show the unit’s output loading.
• 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.
See Section 5.2 for more troubleshooting information.
