Making Connections to the Terminal Board

Each terminal block on the terminal board has a cage clamp connector. One side of the connec-

tor has the actual connection for the wire, with a lever at the top. If there is an option present that

is not properly connected to the terminal board or if adding a new option, connect the wires from

the option as follows:

1. If the option's wires have not been stripped, strip the insulation at the end of wires.

2. Locate the correct terminal block on the terminal board (see Figure 15 on

page 49).

3. Push the lever back at the top connector until you see the opening for wire

insertion. The connectors are spring activated and may require a lot of pressure to

move the lever.

4. Insert the wire into the opening and release the lever.

NOTE

Improperly or inadequately grounded installations can cause

noise or instability in the control loop. The internal electronic

components are isolated from ground. Grounding the case is

unnecessary for functional purposes but grounding the case may

be necessary to conform to local codes. Side loading the cage

clamp lever can cause damage.

Position Retransmit: when wiring this feature:

Wire using the same gauge wire as for the 4-20 mA control loop.

In general, ensure that it is connected to the control system's

analog systems card.

Ensure the control loop is powered when using a meter to make

any measurements.
