Option Installation Remote Stop/Start - Ingersoll-Rand Intellisys SSR 10-40 Serviceman's Manual

operate as long as the plant line-pressure remains above the on line set point
of the Intellisys controller.
If the timer continues to operate for as long as its adjusted time setting, a relay
contact in the Intellisys opens to de-energize the compressor motor starter coil.
At the same time, an amber light on the Intellisys panel is lit to indicate the
compressor has shut down automatically and will restart automatically.
The automatic restart will take place when the line pressure drops to the on line
set point of the Intellisys controller.
INSTALLATION INSTRUCTIONS:
Remove the option prom (39666672) from its package, using care not to
damage the pins on the prom.
Insert the prom into the optional program prom socket located in the center of
the interface board as shown in Figure 1. (Pin #1 on the prom should be located
in the lower left corner for correct installation).
Set the automatic stop time on the Intellisys panel. Press the set button to
initialize the prom function.
Start the compressor and adjust the isolation valve to allow the unit to slowly
reach the off line pressure and unload. The compressor should run for the pre-
set time and then shut down.
The compressor should restart automatically when system air pressure drops
below the on line air pressure setting.

OPTION INSTALLATION REMOTE STOP/START

The remote stop/start option allows the operator to control the compressor from
a remote mounted stop/start station. Two different terminal points are provided
on the interface board, one a connection for a normally closed stop switch
(terminals 3 and 4) and one for a normally open, momentary contact start switch
(terminals 1 and 2).
