General Description

The PCM is part of Paragon Compressor control packages 6BSB000929 and 6BSB000930.

Besides this Application Guide, the following manuals, I/O Zone Installation Guide and I/O Zone Integration Guide are necessary for proper installation and Network Protocol configuration.

Compressor Protection

See Table A & B for Tm control points.

See Table A & B for Td control points.

Run Recognition Signal

The Slide Valve and Compressor Protection functionality are not active until the PCM receives the Run Recognition signal from the System Controller.

LED Indicators are provided in the PCM Controller Kit. Install labels next to each LED light identifying the indication.

Place adhesive label in a location next to the PCM Controller so it is visible for Field Service and Refrigeration Technicians.

PCM Module Inputs

Input #1: Slide-Valve Capacity Control

See Chart ESee Table F

Input #2: Motor Temperature Control

Note: The motor thermistor connection points are located in the compressors electrical box at terminals S1 and C. In the event of a thermistor failure, a spare thermistor is available between S2 and C terminal points.

Table A & B.

Input #3: Discharge Temperature Control

Table A & B

Input #4: Dry Contact for Compressor Oil Protection

Input #5: Compressor recognition signal (received from Master Controller)

Tells the PCM Controller that the compressor is actually on/running. Slide Valve Control and Compressor Protection are activated when the PCM receives the recognition signal that the compressor is on. PCM controller initiates a 15 second delay regarding monitoring input#1 (suction pressure or thermistor temperature). PCM controller allows for a 3 second delay prior to beginning to monitoring inputs and taking action for inputs #2, #3, and #4 (eliminate nuisance trips on startup). When the compressor is off, there will be no oil flow. Therefore the oil flow switch will be open, causing output #5 to open, therefore not allowing the compressor to start. Therefore the controller must ignore the oil flow switch until the compressor is started and actual compressor oil flow is established, resulting in a closed oil flow switch.

Input #6: Dry Contact for Manual Reset

.

Output #5: Enables the Compressor to Run

When output is closed (energized), the compressor is enabled to run and therefore there are no fault conditions. Output must be part of Refrigeration System’s pilot duty Start/Stop Compressor circuit. An alternative to output #5 is the end user receiving this compressor start/stop signal (run enable) via the PCM’s communication port to the System Controller. Output will open (de-energize), tripping the compressor off line if the following fault conditions arise

o High Discharge Temperature o High Motor Temperature o Low oil level o Low oil flow o Faulty pressure transducer (open or short) o Faulty thermistor (open or short)

ZS PRO Display

For permanent installation with the PCM Controller. See the I/O Zone Installation Guide for specifications and installation instruction for the ZS Pro.

• Large, easy-to-read LCD on the ZS Pro can be configured to display virtually any analog or digital value in your equipment. Here are some examples: zone temperature, outside air temperature, energy-saving mode icon, heating set-point, cooling set-point, relative humidity, CO2, VOCs, override time remaining, fan status, compressor status, alarms, and much more. • Occupancy override is simple using the "Manual On" momentary push button on the ZS Pro. A single push switches the zone to an Occupied mode for a preset period of time. The user can increase or decrease the override time with the up or down arrows, and the LCD displays precisely how long the zone will stay occupied. The occupied time increment and maximum override time are fully adjustable. • Zone set-points can be changed on the ZS Pro by pressing the up or down arrow buttons. Setpoint adjust increment amount and the maximum total adjustment are fully adjustable.

RED

Set the configuration jumper for input #1 depending on if the control set-point will be measured via Pressure or Temperature. The jumper comes installed on the PCM and may already be in the correct position.

Place the configuration jumper to this position if the Process Control Variable is a thermistor sensor for Input #1.

OR

Place the configuration jumper to this position if the Process Control Variable is a 0-5 vdc Pressure Transducer sensor for Input #1.

S2

Must set the configuration jumper to this position for Input #2. This sets the type of signal the input will receive as a Thermistor. Failure to do so will result in input #2 not working correctly.
