| A red light on the decoder module |
- Shorted decoder/solenoid or bad connection to controller backplane.
|
- Remove the EZDM, press reset on the back of the panel, then reinstall. If there is a short in the field, the light will remain red until you disconnect path.
|
|
The New Module does not work; the station count is incorrect
|
- Controller was not reset after module installed.
|
- Press Reset button on the back of the control panel.
|
|
Station will not run
|
- Decoder not programmed or programmed to the wrong station
- Decoder or solenoid disconnected
- Bad solenoid
- Bad decoder
|
- Start manual station activation, and verify station is running in the display.
- Inspect decoder, verify the LED is flashing at one-second rate. If not, check for 24VAC at decoder connection to two-wire path.
- If light is flashing, decoder is working, check solenoid and connection to wire leads.
- If necessary, re-program decoder to correct station number.
- Test the decoder at the controller to verify if it is bad. Wire red/blue wires from the decoder directly to the EZDM. Test with manual operation.
- Test with EZDT if applicable. Learn More
- Test red/blue wires for Ohms of resistance with a multimeter.

P/MV will not operate
|
- Decoder not programmed as PM/V
- Wire jumper not installed
|
- Re-program decoder with NO stations running.
- Install jumper wire between EZ-DM PMV terminal, and PMV terminal on controller power module.

Err message in display
Note: When errors occur on the two-wire path, the controller cannot directly identify which station caused a problem (like it can with conventional stations and PMV). Start stations manually to see when the Err occurs.
|
- Overload condition in the field
- Possible short in two-wire path
- Possible duplicate station numbers; too many solenoids active
- (Station number shown in Err display may not be correct with EZ-DM installed)
|
- The solenoid is damaged, causing a high current draw; check resistance.
- If error occurs on all stations, check for dead short in two-wire path or PM/V output.
- Eliminate decoder stations with same number as conventional stations in use.
