Ingersoll-Rand 100-200 HP/75-160 KW - Manual (Page 23)

3.5.1 Lead/Lag- This setpoint is used for setting lead
or lag operation. If set to lead, the controller will load
and unload the compressor by the online and offline
setpoints. If set to lag, the controller will subtract the
lag offset (see 3.5.4) from the online and offline set
points and operate the compressor at the lower
pressure range.
3.5.2 Offline Pressure- This setpoint is the pressure
the compressor will unload at if it is operating in on/off
line mode.
3.5.3 Online Pressure- This setpoint is the pressure
the compressor will load at.
3.5.4 Lag Offset- This setpoint is used with the
lead/lag operation. If the lead/lag set point is set to lag
(see 3.5.1), the value of the lag offset will be
subtracted from the online and offline setpoints.
3.5.5 Mode of Operation- This setpoint is used to
select the operating mode of the compressor. The
choices are MOD/ACS, ON/OFF LINE, and
MODULATION ONLY. See section 5.8 for more
information on these operating modes.
3.5.6 Max Modulation Pressure- This setpoint is the
pressure the compressor will unload at if it is
modulating. As the package discharge pressure rises
toward this value, the inlet valve will start to close. The
compressor will unload once the package discharge
reaches this value. See section 5.8 for more
information on modulation.
3.5.7 Stop Delay Time- This setpoint is the minimum
amount of time the compressor will run unloaded
before stopping. This period does not apply to alarms
(shutdowns).
3.5.8 Star-Delta Time- This setpoint is only used with
star-delta starters. It is not used if the starter is full
voltage or a remote starter. This is the time period
between starting and star-delta transition.
3.5.9 Contrast- This setpoint is used to improve the
display on the Intellisys.

3.6 OPTIONS
Options are turned on or off and their associated
values are set using the OPTION screen.
Some options require additional machine hardware
and the proper “Option Module” to plug into the
Intellisys controller. Descriptions of the options
operations are in Section 7.0. The name and value of
each of the options listed in the right hand column can
be seen by moving the list up and down using the
arrow buttons.
An Option item’s value can be changed the same way
OPERATOR SETPOINTS values are changed. See
Section 3.5 for an explanation.
