Product Information

High-Pressure CO2 Controller

The High Pressure CO2 controller (P/N 818-9010) application is a standalone controller that operates the High Pressure Valve (HPV) and the Bypass Gas Valve (BGV) in a Booster Transcritical CO2 system. The controller has a heat reclaim feature, safety parameter operation for the flash gas receiver tank and calibration feature for the HPV and BGV. For E2 setup information, click here:

Caution

GND is Common, not earth ground. Do not earth ground this device

Locating the Firmware Version for ADF/DSC Ordering

The iPro firmware version is needed to order the corresponding ADF/DSC and can be found on the Visograph Display.

iPro Firmware Version to ADF/DSC Mapping

The previous FM version 160526 is located on the Status screen of the Visograph in the upper right corner. The latest FM version 231001 is located on the Main Menu of the Visograph in the lower right corner (and also on the Status screen).

The High Pressure CO2 Controller I/O Points

The board has 6 analog inputs and 11 digital inputs, with default configurations pre-loaded for quick connection to for gas cooler pressure outlet, gas cooler temperature, flash gas receiver pressure and enable digital input. Its 8 relay outputs, rated 2.0 amps max, are used for activating and deactivating alarms. Its 4 analog outputs may be used for a 0-10 volt signal for external valve driver for either the HPV or BGV.

Independent System Control

The High Pressure CO2 controller can control the HPV and BGV in a refrigeration Booster Transcritical CO2 System. However, the High Pressure CO2 controller is designed to interface with an E2. Networking the High Pressure CO2 controller to a central controller also allows you to view status on E2 and UltraSite32 Site Manager status screens, report alarms, and log point values. The High Pressure CO2 controller configuration can be programmed through the E2 front panel.

Technical Specifications

Analog Inputs

Type of Analog Input: (configurable via software parameter)

| NTC Copeland (-50T110°C; 10KW±1% at 25°C) PTC Copeland (-55T115°C; 990W±1% at 25°C)

Digital input (potential free contact)

Voltage: 0 – V, 0 – 5V, 0 – 10V (input resistance 3.7KW) Current: 0 – 20mA, 4 – 20mA (input resistance 100W)

Accuracy

| NTC, PTC: ±1 0-1V: ±20mV

0-5V: ±100mV

0-10V:±200mV

2-20mA, 4-20mA: ±0.30mA

Additional Power

| +12V: 200mA in total (between +12V and analog outputs)

+5V: 100mA

Caution

Any inputs that are powered with a voltage that differs from that supplied by the device (+12V or +5V) must be powered separately with another transformer (do not use the same secondary of the controller’s power) in order to prevent the inputs from malfunctioning or being damaged.

Digital Inputs

Type: (configurable via software parameter)| Opto-insulated live contact (24VAC/DC) External power 24VAC/DC ±20%
---|---
Number of Inputs| 11
Digital Input Status Variation Detection Time| 100ms (in any case depends on the cycle time set by the user in the given application)

Caution

Use another transformer (do not use the same secondary of the controller’s power) in order to prevent the inputs from malfunctioning or being damaged

Analog Outputs

outputs 0-10VDC

4-20mA (Out1 – Out4)

Maximum Load

| 40mA (Out1 – Out4) max with configured outputs 0-10VDC 400W max with configured outputs 4-20mA

22W per live analog output

Accuracy| Out1 – Out4: ±2% full scale
Resolution| 8-bit

Caution

The electrical devices controlled by these analog outputs must be powered separately with another transformer (do not use the same secondary of the controller’s power) in order to prevent the outputs from malfunctioning or being damaged.

Digital Outputs

Relays with normally open contact

Maximum Load| 5A(250VAC) SPST 5(2)A

Caution

Verify the capacity of the output used. There is double insulation between the digital outputs and the low voltage of the rest of the circuit. Do not use different voltages for the various groups of relays or within each group.

Choosing Transformer Sizes

The transformer used to power the High Pressure CO2 controller should have a minimum rating of 30VA. The High Pressure CO2 controller should not share a transformer with any other devices.

Compatible Transformers with CO2 Controller

Neither side of the secondary should be connected to ground. Also, do not connect the center tap (if provided on the transformer) to ground. The entire secondary of the transformer should be isolated from any ground.

Wire Types

For powering I/O boards, use only the listed wire type below. Two-conductor non-shielded cables are the recommended wire for connecting the transformer to the High Pressure CO2 controller. Shielded cable should not be used for power wiring. The center tap should be left disconnected if present on the transformer

Wiring

NOTE To ensure control in case of a power failure, it is recommended that a UPS be used on the High Pressure CO2 controller.
