Checking Out the Wiring and Grounding

Repeat this procedure to check out each of the four axis loops

connected to the IFM terminal block.

ATTENTION: Be sure to remove all power to the SLC processor,

LDT, valve and pump beforehand.

1. Disconnect the LDT connector at the head end.

2. Disconnect the connector to the IFM terminal block.

3. Turn ON the power supplies for the LDT and SLC processor, and

check the LDT connector and IFM terminal block for:

• +15V dc

• PS common

• –15V dc

4. Observe that the module’s fault LED indicates Green.

5. Verify continuity between IFM COM terminal (50) and each of:

• shield of the amplifier output cable to the valve

• output common on
