Inspecting Your Module

You can prevent many potential problems by simply inspecting your

analog module:

1. Ensure that all wire connections are correct and secure and that no

wires are missing or broken.

CAUTION

Before enabling a channel (through your ladder program),

ensure that you have not connected a voltage source to a

channel configured for a current input (and vice versa).

Failure to observe this precaution can cause improper module

operation or equipment damage.
