CURRENT SENSOR INSTALLATION

CURRENT SENSOR INSTALLATION DIRECTIONS WARNING! DISCONNECT POWER FROM SUB PANEL BEFORE BEGINNING.

1) After verifying that power has been turned off at the sub panel, remove the two or three main feed lines from terminal blocks. Slip the main lines through the holes in the Current Sensor and re-connect to terminal blocks. (Make sure current sensor “switching circuit” and “power feed” screws are in the location as shown in diagram below).

2) Mount Mercury Displacement Relay in the back or on the side of the sub panel. (Must be installed vertically as shown in diagram below).

3) Remove the wire from the circuit breaker that powers the conveyor outlet and connect it to the top lug of the Mercury Displacement Relay.

4) Install 18 GA wire from the current sensor “power feed” screw to the Mercury Displacement Relay bottom lug.

5) Install 12 GA wire from the conveyor circuit breaker through the current sensor and connect to the Mercury Displacement Relay bottom lug. NOTE: Wire must be run through current sensor hole on the same leg as the conveyor circuit breaker. (See diagram below for proper way to route the wire).

6) Install 18 GA wire from the neutral strip to the Mercury Displacement Relay (east) lug.

7) Install 18 GA wire from the current sensor “switching circuit” screw to the Mercury Displacement Relay (west) lug. NOTE: If your sub panel main lines have any other hot lines besides the pitching machine outlets and conveyor outlets going through the current sensor (such as sump pump, lights, etc... ) this could result in the conveyor and hoppers running continuously. To correct this problem you must cancel out the circuit (See step 5 for proper way to cancel out the circuit). If you have any further questions contact ABC’s Service Department.
