Why won't my Ampcontrol Relay close and indicates an EC fault?
If an Ampcontrol Relay won't close and shows an EC fault, it could be due to a faulty pilot circuit, such as an open, high resistance, or shorted to earth. Try operating the relay with a dummy plug if in diode mode. If the issue persists, the pilot fuse should be checked. If the relay remains faulty after these checks, consider replacing it.
What to do if Ampcontrol Relay displays ‘Outlet Close Fail’ message?
If an Ampcontrol Relay displays an 'Outlet Close Fail' message after start, it means the relay’s MCI input isn't closing within 5 seconds of the MCR relay pickup. Verify that the main contactor is closing. If it's not, inspect the circuit or replace the main contactor. Also, check the auxiliary contacts and wiring.
Why does Ampcontrol Relay RDM display ‘Tripped-No Volts’ message?
If the Ampcontrol Relay's RDM displays a 'Tripped-No Volts' message, the relay isn't receiving voltage feedback on one or more of the outlet phases when the contactor is closed. Check the system voltage display as the contactor closes and compare it with the undervoltage threshold. Also, check continuity from the relay, through the EFLO Test Module to power conductors by testing each phase to earth at the outlet, provided the circuit is isolated. A typical reading should be around 2655 kΩ.
What causes Ampcontrol Relay to trip on MCF on power up?
If an Ampcontrol Relay trips on MCF during power up, it could be due to a main contactor fail condition, such as leakage across terminals or a frozen contactor. You should check the main contactor. Another potential cause is a flat or faulty battery; if this is the case, it is recommended that the relay be returned to Ampcontrol for battery replacement and full testing.
How to troubleshoot a blank screen on Ampcontrol IPD remote display?
If the remote display for your Ampcontrol Relay shows a blank screen and the RDM Healthy LED is off, it could be due to a loss of power to the display. Ensure the relay has power and is correctly plugged in, as the relay provides 15V DC to the RDM. Check the cable connecting the RDM and the relay. Another possibility is a faulty display module, which would require replacement.
What does 'Locked Out - Fan' status mean on Ampcontrol Relay?
If your Ampcontrol Relay displays a 'Locked Out - Fan' message, the relay is waiting for the fan interlocking system. If interlocking isn't needed, connect a 10 kΩ resistor between terminals 9 and 12. If fan interlocking is used, ensure the fan is running and the current threshold setting in the fan outlet’s RTU is correct. The Fan Outlet IPD should pick up its FID signal, which causes all other relays to pick up their FIR signal. Check these conditions at level 6, position 4. Also, check the wiring between the fan relay and other relays (terminal 9).
How to fix Ampcontrol Relay RTU Memory Error?
If an Ampcontrol Relay displays an RTU Memory Error, it indicates that either the RTU is not online or the RTU’s non-volatile memory has been corrupted. First, check that the RTU is online (level 3, position 1), ensuring a healthy pilot loop. If the RTU is online, examine the Group 2 Settings stored in the RTU (level 9). If any settings show '???', reprogram the lost settings into the RTU memory.
What does IPD Memory Error mean on Ampcontrol Relay in diode pilot mode?
If your Ampcontrol Relay shows an IPD Memory Error in diode pilot mode, there may be corruption in the Group 1 or 2 settings stored in the IPD Relay. Examine the Group 1 and 2 Settings (level 8 and 9) to check the stored parameters in the non-volatile memory. Re-program lost settings into the memory.
How to resolve IPD Memory Error on Ampcontrol Relay in RTU pilot mode?
If an Ampcontrol Relay displays an IPD Memory Error in RTU pilot mode, it indicates corruption in the Group 1 Settings in the IPD Relay. Examine the Group 1 Settings (level 8) to check the stored parameters in the non-volatile memory. Re-program lost settings into the memory.
Why does Ampcontrol Relay time and date reset on power up?
If the time and date are incorrect and reset to 1/01/9? on power up for your Ampcontrol Relay, it is likely due to a low IS battery. It is recommended that the relay be returned to Ampcontrol for battery replacement and full testing.
