15. Troubleshooting
If a problem is experienced with the relay, use the following tables to fault find the problem. Should the fault
persist, remove the relay and return the relay, plus a description of the fault, to Ampcontrol for repairs.
Note: Checking the Status page (level 0, position 0) should be the first step in troubleshooting. This displays
what the relay requires to make it operate. Also check the first six event logs.
