E-ISO Analog SLC Fault Isolator Module
Installation Sheet
Operation
The module is an analog addressable device used to protect a
Class A SLC from total collapse due to wire-to-wire short
circuits. The module monitors line voltages and opens the SLC
when a short is detected. A short is isolated between the two
modules located electrically closest to the short.
The device address is set using the two rotary switches located
on the front of the module. One device address is required.
LED operation
The module provides a bicolor LED that shows its status.
Normal: Green LED flashes
Active: Red LED flashes
