Replacement:

Note

When replacing connectors J1, J2, and J3 do not reverse the connector. The connector can be forced on in the opposite direction.

Reversing any connector can cause incorrect operation of the transmitter. Refer to figure 8, view A, for proper insertion of the

connectors.

1. Check the printed wiring board for correct jumper configuration. Refer to table 10.

Table 10. Jumper Configuration

Type

4210/4220

4212/4222

4215

* See figure 5 for jumper locations on the printed wiring board.

NOTES:

1. The three wire cable assembly connected to J3 provides the position switch circuit output to relays K1 and K2 on the field circuit printed wiring board.

2. Terminal block number 1 (TB1) provides the connections for the three wire cable assembly from the potentiometer. On a dual potentiometer system, it provides the transmitter input

only.

3. Connector J2 is only used with a dual potentiometer or for position switches without transmitter circuit. It provides the position switch circuit input to the printed wiring board.

4. The two wire cable assembly connected to J1 is used for the transmitter output signal, (4 to 20 milliamperes), and is connected to the RFI filter.

2. When the replacement board is ready, lower the board into the transmitter compartment.

3. Insert and tighten the three screws.

4. Install the plug connections that were removed.
