5-2.2.5 TRIAC Outputs
The following items should be checked and verified for proper operation of the TRIAC Outputs on
applicable controllers:
• Verify correct polarity of the wiring connected to the TRIAC outputs.
• Inspect the controlling device for any defects or problems.
• Verify that the current draw for any contactors are within the tolerance of the TRIAC outputs.
• Power ON the TRIAC output (force ON using MAXMon).
• Check the TRIAC output voltages and verify proper operation of the controlling device

A TRIAC output cannot be tested without a load applied. Therefore a load of a minimum current rating of 20mA
must be applied for correct operation of the TRIAC outputs.
