Corrective Maintenance Table 6–13. Microchron II Timer Electronics Replacement Procedure Step Procedure 1 For the DC version of this relay install the Motherboard and go to Step 5. NOTE Always handle printed circuit boards at a static safe station. For the AC version of this relay, go to Step 2. 2 Place the electronics package/bracket assembly onto the relay base. 3 Confirm that the wires to the white, 4-position connector run through the notch in the bracket. 4 Use the two flathead screws and washers from Step 3 of Table 6–12, the Timer Electronics Disconnect and Removal Procedure, to secure the assembly to the relay base and tighten firmly. 5 Connect the smaller, square shaped, 4-position connector P2 to the thumbwheel board. The connector is keyed and only fits in one position. Top View of AC Relay (J1) (P1) (P2) 6 Connect the four-position connector, P1 (located close to the relay base) from the Motherboard (DC version) or Timer board (AC version). 7 Visually inspect the relay to verify that no wires are pinched between the relay base and the Motherboard (DC version) or Timer board (AC version).
