1. Reset and sequence the relay module.
2. If fault reappears, remove power from the device, reapply power, then reset
and sequence the relay module.
3. If fault does not repeat on the next cycle, check for electrical noise being
copied into the relay module through the external loads or possibly an
electrical grounding issue.
4. If the fault persists, replace the relay module.
1. Check wiring and operation of special OEM inputs.
2. Reset and sequence the relay module.
3. If fault reappears, remove power from the device, reapply power, then reset
and sequence the relay module.
4. If the fault does not repeat on the next cycle, check for electrical noise being
copied into the relay module through the external loads or possibly an
electrical grounding issue.
5. If the fault persists, replace the relay module.
1. Make sure Relay Module VP is programmed.
2. T6 and T17 powered at the same time—correct wiring.
