17.4.10 Low Resolution Sensor Wiring

The refrigeration pressure transducers should be connected to P4 as follows (see P4 in the Olympic Board

photo below): A typical transducer configuration for a cascade refrigeration system is listed in the table

below. Note that the Low Resolution inputs are not limited to pressure measurement and can be used for

any transducer compatible with the 5VDC full scale or 4-20 mA signal conditioners.

Sensor Function Range Voltage Range Connection COM

Low stage, Discharge Pressure 0-600PSI 0-5 VDC P4-pin 1 P4- Pin 10

Low stage, Suction Pressure 0-200PSI 0-5 VDC P4-pin 2 P4- Pin 10

Low stage, Oil Pressure 0-200PSI 0-5 VDC P4-pin 3 P4- Pin 10

High stage, Discharge Pressure 0-600PSI 0-5 VDC P4-pin 4 P4- Pin 10

High stage, Suction Pressure 0-200PSI 0-5 VDC P4-pin 5 P4- Pin 10

High stage, Oil Pressure 0-200PSI 0-5 VDC P4-pin 6 P4- Pin 10

Pressure scaling is setup in the Low Res Input Calibration Setup screen as shown below:

Example 1

In this example the low stage compressor

discharge pressure is monitored on Input 1. The

high engineering scale is set to 600 for 600 PSI.

Example 2

In this example the low stage compressor suction

pressure is monitored on Input 2. The high

engineering scale is set to 200 for 200 PSI.

The Low Resolution inputs can be viewed in the Events/Low Res screen. These inputs can be used as the

input for a programmable alarm

in addition to be used as the sensor for a control channel.
