AE8-1385

INTRODUCTION

Overview

CoreSenseDiagnostics is a breakthrough innovation for troubleshooting residential air conditioning and heat pump systems. The CoreSense Diagnostics module is easily installed in the unit electrical panel near the compressor contactor. By using the compressor as a sensor, CoreSense Diagnostics helps the service technician more accurately troubleshoot system and compressor fault conditions.

CoreSense Diagnostics also provides compressor and system protection through its proprietary lockout feature. Depending on the severity and frequency of the fault that caused the trip condition, the CoreSense Diagnostics module can lockout the compressor contactor to prevent damage to the compressor and system components. Less severe fault conditions resulting in an occasional trip will not result in a lockout condition.

Flashing LEDs communicate ALERT and LOCK codes to the service technician.

Application Restrictions and Types

The CoreSense Diagnostics (571-0072-00) module is designed and qualified for use with ZPS*K5 single- phase Copeland Scroll® UltraTechcompressors.

Product Specifications

Operating Temp: - 40° to 150°F (- 40° to 65°C)

Storage Temp: - 40° to 175°F (- 40° to 80°C)

Supply Voltage: 18 to 28VAC , 48 to 62Hz

Module Current Sensing Range: 2 to 30A

Maximum Power Consumption: 2.5 VA (Excluding solenoid load)

INSTALLATION

Mounting

Four #8 or #10 self tapping or sheet metal screws are required for installation of the module. The maximum mounting screw torque is 20 in.lbs. Locate the module near the compressor contactor (wire routing for compressor run, common, and start wires will be easier in this position). The module can be mounted in any orientation and LEDs should be visible for ease of service.

The compressor’s run (R), common (C), and start (S) wires are routed through the holes in the CoreSense module marked “R”,”C”, and “S”. See Figure 1.

Terminal Description

The terminals for the CoreSense Diagnostics module are ¼” spade terminals.

COMMON (C)

The 24 volt common terminal for module power.

DEMAND (Y)

The demand terminal requires a 24VAC signal measured with respect to the COMMON (C) terminal when there is a call for heating or cooling. A signal above 6VAC indicates the thermostat wants the compressor to be on, while 0-6VAC signal indicates the thermostat wants the compressor to be off.

SECOND STAGE DEMAND (Y2)

The demand (Y) and second stage demand

(Y2) terminals require a 24VAC signal measured with respect to the COMMON (C) terminal when there is a call for heating or cooling. A signal above 10VAC indicates the thermostat wants the Ultratech solenoid to be energized, while 0-10VAC signal indicates the thermostat wants the Ultratech solenoid to be deenergized.

PROTECTION (PROT)

The protection terminal is internally connected to the COMMON terminal through a solid state switch.

POWER (R)

The module requires a constant 24VAC supply power to this terminal. The module must receive an independent power supply in order to operate properly. See Figure 4.

Thermostat Communication (L)

Provides a 24V signal to an indoor thermostat indicating the number of ALERT flashes displayed on the module. (Reference thermostat manual for available capability)

Solenoid (DC SOL)

Provides a connection to the Copeland Scroll UltraTech second stage compressor solenoid. This solenoid is internal to the compressor, and has

a voltage range of 18 to 28VDC. Please refer to bulletin AE-1311for information on the Copeland Scroll® UltraTech® compressor.
