ATTENTION

This is a Class 1 Laser/LED product. Do not stare into the

laser

beam.

Redundant Power Inputs

Both power inputs can be connected simultaneously to live DC power

sources. If one power source fails, the other live source acts as a backup,

and automatically supplies all of the IMC-101’s power needs.

Alarm Contact

The IMC-101 has one alarm contact located on the top panel. For detailed

instructions on how to connect the alarm contact power wires to the two

middle contacts of the 6-contact terminal block connector, see the

“Wiring the Alarm Contact” section above. A typical scenario would be to

connect the Fault circuit to a warning light located in the control room.

The light can be set up to switch on when a fault is detected.

The alarm contact has two terminals that form a Fault circuit for

connecting to an alarm system. The two wires attached to the Fault

contacts form an open circuit when (1) the IMC-101 has lost power from

one of the DC power inputs, or (2) one of the ports for which the

corresponding PORT ALARM Dip Switch is set to ON is not properly

connected.

If neither of these two conditions occurs, the Fault circuit will be closed.
