1. Use diagram on the previous page for references to troubleshooting the ED2.0 board
2. Disconnect source power to outdoor breaker
3. Warning: removing cover exposes live voltage
4. Remove the two #4 screws holding on the Push button plate and let it hang down
5. Remove the four .250 X 20 screws from the corners of the ED2.0 cover
Follow these instructions for a quick setup check on a breaker that has operated previously:
READY
LIGHT IS OFF:
1. Check pins 2 and 3 on KM1003 to confirm proper input voltage is applied.
2. Verify that there is 18 VDC on terminals 1 (-) to 3 (+) on KM1001.
3. Verify there is 80 VDC from KM1002 1 (-) to 3 (+).
4. If correct voltage is applied and DC is not reading, then the board needs to be replaced.
READY
LIGHT IS ON:
Check proximity sensors located on top of the mechanism. The metal guard will have to be
removed prior to inspection. When the sensor is properly positioned, you will see a yellow light
on the rear of the sensor for each breaker position. When breaker is closed, the upper sensor
will be lit. When open, the lower sensor will be lit. The gap between the sensor and the metal
flag must be not be greater than .045. If this gap is incorrect, the sensor may not see the position
of the breaker.
