101Replacing Defective Processor Modules —The module replacement part number is printed on a smalllabel on the rear of the ICVC module. The chiller model andserial numbers are printed on the chiller nameplate located onan exterior corner post. The proper software is factory-installedby Carrier in the replacement module. When ordering areplacement chiller visual control (ICVC) module, specify thecomplete replacement part number, full chiller model number,and chiller serial number. The installer must configure the newmodule to the original chiller data. Follow the proceduresdescribed in the Software Configuration section on page 64.INSTALLATION1. Verify the existing ICVC module is defective by using theprocedure described in the Troubleshooting Guidesection, page 82, and the Control Modules section,page 100. Do not select the ATTACH TO NETWORKDEVICE table if the ICVC indicates a communicationfailure.2. Data regarding the ICVC configuration should have beenrecorded and saved. This data must be reconfigured intothe new ICVC. If this data is not available, follow theprocedures described in the Software Configurationsection. If the module to be replaced is functional, config-urations may also be copied manually. The data sheets onpages CL-3 and CL-11 are provided for this purpose.Default values are shown so that only deviations fromthese need to be recorded.If a CCN Building Supervisor or Service Tool is avail-able, the module configuration should have already beenuploaded into memory. When the new module isinstalled, the configuration can be downloaded from thecomputer.Any communication wires from other chillers or CCNmodules should be disconnected to prevent the newICVC module from uploading incorrect run hours intomemory.3. Record values for the TOTAL COMPRESSOR STARTS,SERVICE ONTIME and the COMPRESSOR ONTIMEfrom the MAINSTAT screen on the ICVC.4. Power off the controls.5. Remove the old ICVC.6. Install the new ICVC module. Turn the control powerback on.7. The ICVC now automatically attaches to the localnetwork device.8. Set the current time and date in the SERVICE/TIMEAND DATE screen. Set the CCN Bus and Address in theSERVICE / ICVC CONFIGURATION screen. Press thealarm RESET softkey (from the default screen). Uploadvia Service Tool or manually reenter all non-defaultconfiguration values. (Refer to pages CL-3 throughCL-11.) If the correct VFD Configuration values aredisplayed in the VFD_CONF table when that table isviewed, simply press EXIT then SAVE to reload allof them. Use Service Tool or manually reenter TOTALCOMPRESSOR STARTS, SERVICE ONTIME andCOMPRESSOR ONTIME. If forced using Service Tool,Electrical shock can cause personal injury.
