CARRIER 19XR04012203 CEPL130259-07-R

Overview

CARRIER 19XR04012203 CEPL130259-07-R is the ISM Integrated Starter Module for Carrier 19XR centrifugal chiller. CEPL130259-07-R represents the PCB revision and firmware version, while 19XR04012203 is the official Carrier spare part number. This module is a critical starter and protection controller for the chiller compressor motor, widely supplied as exchange spare for large centrifugal chiller control cabinet overhaul and replacement.

Features

CARRIER 19XR04012203 CEPL130259-07-R manages the complete motor starting sequence, including pre-lube check, start permissive logic, soft-start coordination, breaker control and run monitoring for the centrifugal compressor motor. It integrates multi-point discrete input and output terminals to interlock with oil pressure, water flow, vibration, temperature and safety trip circuits. CARRIER 19XR04012203 CEPL130259-07-R samples motor current and voltage signals to detect overload, locked rotor, phase loss and reverse phase conditions. It communicates status, start sequence progress and fault codes to the chiller main controller via dedicated internal bus, supporting alarm display on the chiller operator panel and remote BMS/SCADA logging. CARRIER 19XR04012203 CEPL130259-07-R stores start records and trip history for service troubleshooting. It is equipped with front status LEDs for power, run, fault and communication activity. It supports hot-swap maintenance under proper shutdown procedure and is configured via Carrier chiller service software. It meets HVAC and refrigeration industry safety standards for chilled water plant installation.

Specs

CARRIER 19XR04012203 CEPL130259-07-RPlatform: Carrier 19XR centrifugal chiller Type: ISM integrated starter module Part number: 19XR04012203 PCB revision: CEPL130259-07-R Functions: motor start sequence, permissive interlock, phase and overload protection, breaker command I/O: discrete contact inputs and relay outputs Communication: internal chiller control bus Mounting: slot installation inside 19XR control cabinet This is not the main chiller CPU board or I/O board; it is the dedicated compressor starter and protection module. CARRIER 19XR04012203 CEPL130259-07-R is widely supplied as service replacement spare for chiller starter loop failure.

Principle

CARRIER 19XR04012203 CEPL130259-07-R receives start commands from the chiller main controller. Before enabling the motor starter, it verifies all safety permissive signals such as oil pressure, chilled water flow and anti-surge status. If all conditions are satisfied, the module issues a command to close the motor starter and monitors motor inrush and running current continuously. If phase imbalance, loss of phase, overload or safety interlock dropout occurs, the module immediately triggers a stop command, records the fault code and locks out the start sequence until reset by maintenance personnel.

Applications

CARRIER 19XR04012203 CEPL130259-07-R is deployed for large 19XR centrifugal chillers used in district cooling plants, data centers, hospital central air conditioning and industrial chilled water systems. It is selected for spare inventory and cabinet retrofit projects for existing Carrier 19XR chiller starter control systems.
