11.0 INSTRUCTIONS FOR CHANGING OUT AN ED2.0 CONTROL BOARD
Warning: removing the cover exposes live voltage.
1. Disconnect the source power to the R-MAG.
2. Remove the two #4 screws holding on the Push button plate and let it hang down.
3. Remove the four .250 X 20 screws from the corners of the ED2.0 cover.
4. With the cover removed, verify the voltage input to the board is off by measuring the
voltage at KM1003 terminals 2 and 3. It should be zero.
5. Before proceeding, discharge the capacitors by jumpering KM1003 pins 4 and 5. The time
constant is 33 minutes. A smaller external resistor can be used for a quicker discharge, but
the discharge current should be restricted to 10 amperes maximum. This means that no
lower than 10 ohms 25 watt external resistance should be used to perform capacitor dis
charging. When discharging with a external capacitor, connect to pins 2 and 3 on KM1002.
6. After the capacitors are discharged, take a small screwdriver and remove the capacitor plug.
