General Information
The Intellisys S3 Controller is designed as a
global controller to be used on all 90 - 160kW
(125 - 200Hp) units. This Controller has
replaced all wording with symbols eliminating
the need of multiple language programming. The
below picture shows the basic layout of the S3
controller, this controller is designed for easy
use by the end-user as well as the service
technician.
This controller was developed to be used in both
rapidly Developing Economies as well as
Developed Markets around the world making
this controller a common worldwide solution for
the Rotary Screw compressor line.
The S3 controller controls all aspects of machine
operation including; starting, stopping, loading
and unloading, safety shutdowns, user interface,
©2008 Ingersoll Rand Company Page 2
and compressor remote connectivity to other
devices.
This controller is offered in either a standard
configuration or an enhanced configuration. The
differences will be indicated in this manual by
show the following guides after each input or
output device or software function.
Std – Standard Controller
Enh – Enhanced Controller
The S3 controller has three (3) Analog Inputs,
one (1) Analog Output, eight (8) Digital Inputs,
and six (6) Digital Outputs. This controller also
has capabilities of using both Multi-485 and
Modbus communication protocols.
Component Review
Analog Inputs
4APT [Std] – This pressure transducer used to
convert the package discharge pressure of the
compressor into a 4-20ma analog signal to the
controller. This sensor has a supply voltage of
24VDC, and wired into terminal block XO5 pins
1 & 2 on the backside of the controller. The
output analog signal ranges from 4ma at 0 psi to
20ma at 232psi.The output signal is processed
by the Intellisys and depending on the voltage
the controller may cause a change in the
pressure readout on the display, load or unload
the compressor, or even shut the compressor
down if conditions dictate.

There are no adjustments to this pressure
transducer and if problems arise, the transducer
will need to be replaced. Although the
transducer is non-adjustable, it must be
calibrated periodically. Calibrating the
transducer allows the controller to read the
transducers output at zero gauge pressure and
make any corrections in deviation from the 4ma.
This sensor has an accuracy of 0.5%.
Sensor calibration will be discussed later in this
handbook.
3APT [Enh]– This sensor is the same as 4APT
and can be interchangeable however, 3APT
measures the pressure from the wet side of the
sump. Only available with the enhanced
controller option, this transducer is connected to
the controller at terminal XO5 pins 5 and 6.
2ATT [Std] – This 10K ohm NTC (negative
temperature coefficient) thermistor is located at
the airend discharge. This thermally sensitive
resistor increases the resistant value as the
temperature decreases. It is wired into the
controller at terminal XO5 pins 3 and 4. The
thermistor has a range of -34 to 124°C (-29 to
255°F) the following pages shows the
relationship between resistance and
temperature for this thermistor.
