What to do if the Magnetek FLEX M Receiver MLC Relay turns off during normal operation?

  There are several possible reasons for this. The transmitter may have powered down due to inactivity; try extending the inactivity timeout setting for the transmitter. Alternatively, the transmitter batteries might be low, so replace them. If the RF/Message LED stops blinking for more than 3 seconds before the MLC Relay turns off, radio interference might be the issue; in this case, change the system's channel setting. Lastly, if the RF/Message LED stopped and the MLC Relay turned off together within 1 sec, possibly when engaging or disengaging another relay that is driving a contactor, the CPU module may be resetting; install snubbers across the coils of all contactors to reduce transient voltages and ensure that the power module has a stable power source.

  Inconsistent responses can occur if the transmitter is going in and out of range; try moving the transmitter and receiver closer together. You can also relocate the receiver antenna to a location with a better line of sight to the transmitter. Also, inspect the antenna and/or cable on the receiver for damage and ensure it's properly installed and visibly located during equipment operation.

  If the receiver won't turn on and the +5VDC CPU/RELAY LEDs on the Power Supply Module are not lit, first, ensure the supplied voltage is within the acceptable range (120VAC nominal). If the voltage is correct, the internal fuse may have blown on the power supply module, or there may be an internal power supply problem on the PCB; in either of these cases, contact the factory for repair.

  Several factors could be the cause. First, if the WDG/Online LED is blinking twice, and the RF MSG LED isn't blinking, ensure both the receiver and transmitter are within range and that the transmitter is powered on. Second, if the WDG/Online LED blinks once, RF MSG LED doesn't blink, but RF Signal Strength LEDs show a signal, verify that the receiver and transmitter share the same access code. Third, if the WDG/Online LED blinks once, RF MSG LED doesn't blink, and RF Signal Strength LEDs indicate an erratic signal, ensure both are set to the same channel. A fourth possibility is that the WDG/Online LED is blinking three times, indicating a read/write error with relay modules. In this case, make sure the modules are securely connected; if it continues, contact factory for repair. Finally, ...
