Introduction

The Multipurpose Controller Open XP (MPC Open XP - #OPN-MPCXP) provides monitoring and control for a variety of HVAC system applications. The MPC Open XP supports multiple I/O configurations for both common and custom HVAC control and connects to up to 20 field points directly (8 outputs and 12 inputs).

Introduction

The MPC Open XPIO48 (#OPN-MPCXPIO48) and MPC Open XPIO816 (#OPN-MPCXPIO816) are expanders that connect to the expandable MPC Open XP to increase the number of inputs and outputs. To add inputs or outputs to the MPC Open XP, you can attach up to 3 expanders, using any combination of MPC Open XPIO48 and/or MPC Open XPIO816 expanders connected to the Xnet.

CAUTIONS

Installing the MPC Open XP

To install the MPC Open XP:

1 Mount the controller (page 7).

2 Wire the controller for power (page 7).

3 Set the controller's address (page 8).

4 Wire the controller to the BACnet MS/TP or BACnet ARC156 network (page 9).

5 Wire inputs and outputs (page 14).

6 Wire expanders to the controller (page 10).

7 Wire devices to the Rnet port (page 19).

When you handle the MPC Open XP:

• Do not contaminate the printed circuit board with fingerprints, moisture, or any foreign material.

• Do not touch components or leads.

• Handle the board by its edges.

• Isolate from high voltage or electrostatic discharge.

• Ensure that you are properly grounded.

Screw the MPC Open XP into an enclosed panel using the mounting slots on the cover plate. Leave about 2 in. (5 cm) on each side of the controller for wiring. See mounting dimensions in Specifications.

If using expanders, see Installing an expander (page 10) before mounting the controller.

• The MPC Open XP is powered by a Class 2 power source. Take appropriate isolation measures when mounting it in a control panel where non-Class 2 circuits are present.

• Carrier controllers can share a power supply as long as you:

• Maintain the same polarity.

Do not apply line voltage (mains voltage) to the controller's ports and terminals.

Nickel/Iron - 1 kOhm at 70°F (21°C) Balco TS8000 - 1 kOhm at 70°F (21°C) Input voltages should be from 0.6–1.2 V

For improved accuracy, Carrier recommends using an external current transducer-

Pulse counter 2

sensors require different jumper settings and different wiring arrangements.

Pulse counting up to 40 pulses per second. Minimum pulse width (on or off time) required for each pulse is 12.5 msec.

To use a thermistor or RTD not listed above, you can set up a custom translation table for your sensor.

The MPC Open XP can perform pulse counting for dry contact or voltage inputs if you assign the input to a Pulse

to Analog Input microblock.

If you have one or more RTD's connected to the inputs, the total current draw of all Thermistor, RTD, and Dry contact devices wired to the inputs should not exceed 10 mA. Exceeding this limit affects the accuracy of the RTD's. Use the following approximations as a reference:

• 10 kOhm Thermistor draws approximately 0.334 mA.

• 1 kOhm RTD draws approximately 0.834 mA.

• Dry contact draws approximately 1 mA.

For example, if using an expander with 12 RTD's connected to the inputs, the remaining 4 inputs cannot be used. This assumes negligible wiring impedance (<10 Ohms) for each RTD input, with up to 100 feet of 22 AWG cable.

NOTE

To wire ZS sensors to the controller

NOTES

Use the specified type of wire and cable for maximum signal integrity.

Description 4 conductor, shielded or unshielded, CMP, plenum rated cable

Conductor 22 AWG (7x0096) bare copper if Rnet has only sensors

Maximum length 500 feet (152 meters)

Insulation Low-smoke PVC (or equivalent)

Color Code Black, white, green, red

Shielding If shielded, Aluminum/Mylar shield (100% coverage) with TC drain wire, terminated

at controller

Voltage 300 Vac, power limited

Listing UL: NEC CL2P, or better

ZS Sensors are thermistor-based temperature sensors that may optionally sense humidity, CO2, or VOC. ZS Sensors are wired to the Rnet port on i-Vu® Open controllers. You can use the following ZS sensors:

• ZS Standard

• ZS Plus

• ZS Pro

• ZS Pro-F

• The ZS CO2 model uses 190 mA during sample period. Use auxiliary 12 Vdc, unless it is the only device on

the Rnet port.

• A control program can use no more than 5 ZS Sensors

• SPT sensors cannot share the Rnet with other devices.

• For detailed instructions, see the ZS Sensor Installation Guide.

The Carrier wireless sensors are available in 868, 902, and 928 MHz radio frequency. The sensors are thermistorbased temperature sensors that may optionally sense humidity.

Wireless sensors communicate through a Wireless Adapter, which is wired to the Rnet port of the controller.

• A v6.5 or later i-Vu® system

Do not apply line voltage (mains voltage) to the Wireless Adapter.

• v6-xx-xxx or later controller drivers

To configure the control program for the desired user interaction with the sensor, see the Wireless Sensors Application Guide. For detailed instructions, see the Wireless Sensors Installation Guide.

The MPC Open XP's 10-year Lithium CR123A battery retains the following data for a maximum of 720 hours during power outages: time, control programs, editable properties, schedules, and trends. To conserve battery life, you can set the driver to turn off battery backup after a specified number of days and depend on the archive function to restore data when the power returns. A low battery is indicated by the replacement batteries from any retailer that sells a CR-123A battery.

Important notes about AHU application I/O points

The MPC Open XP accepts any of the following:

• UC applications in the UC equipment sal library

• Any application from the CV AHU or VAV AHU library

• User-created Snap programs

of the 39m AHU applications in the 39m sal library are used, the I/O channels are pre-assigned for the UC Open XP, UC Open, or AppController. These channel assignments are NOT correct in the MPC Open XP.

When using 39m AHU applications in the MPC Open XP or expanders, you must reassign the correct hardware channel numbers in the i-Vu® application or Field Assistant. See To install the <ALCProduct01 into an i-Vu® Control System (page 25). When installing the MPC Open XP with any of the 39m AHU applications, do not connect any I/O channel wiring until you have set the I/O channel numbers specifically for the application.

These cautions pertain ONLY to using 39m AHU applications in the MPC Open XP. UC library applications and Snap applications come with the channel numbers set to 0:0 and you set them to match the application. No special steps are required.

We do NOT recommend using the 39m library applications in the MPC Open XP controller. If any
