Controls
The LIM module contains two push buttons, ANALYZE/STORE and TEST/STEP, and a rotary line-
select switch. The button functions for the Normal mode are ANALYZE and TEST, and are
STORE and
STEP in the program mode.
In the Normal mode, pressing the ANALYZE button causes any fault condition on the line currently
selected by the rotary switch to be displayed on the fault-descriptive LEDs:
 Line SHORT
 Line OPEN
 LEAK
Set-Up
Install the LIM modules in the central cabinet using the standard “snap-track” style mounting. Ensure the
push button controls and the LED indicators are easily accessible to the operator or technician for
diagnostic tools. Refer to the system block diagram on page 3.
