Chiller Control Module (CCM) (Fig. 41)

INPUTS — Each input channel has 2 or 3 terminals. Refer to individual chiller wiring diagrams for the correct terminal numbers for your application.

OUTPUTS — Output is 24 vac. There are 2 terminals per out- put. Refer to the chiller wiring diagram for your specific appli- cation for the correct terminal numbers.

Integrated Starter Module (Fig. 42)

INPUTS — Inputs on strips J3 through J6 are analog inputs and J2 is discrete (on/off) input. The specific application of the chiller determines which terminals are used. Refer to the indi- vidual chiller wiring diagram for the correct terminal numbers for your application.

OUTPUTS — Outputs are 115-277 vac and wired to strip J9. There are 2 terminals per output.

Replacing Defective Processor Modules —

The module replacement part number is printed on a small label on the rear of the CVC/ICVC module. The chiller model and serial numbers are printed on the chiller nameplate located on an exterior corner post. The proper software is factory- installed by Carrier in the replacement module. When ordering a replacement chiller visual control (CVC/ICVC) module, specify the complete replacement part number, full chiller model number, and chiller serial number. The installer must configure the new module to the original chiller data. Follow the procedures described in the Software Configuration section on page 55.

Electrical shock can cause personal injury. Disconnect all electrical power before servicing.

INSTALLATION

1.Verify the existing CVC/ICVC module is defective by us- ing the procedure described in the Troubleshooting Guide section, page 76, and the Control Modules section, page 87. Do not select the ATTACH TO NETWORK DEVICE table if the CVC/ICVC indicates a communica- tion failure.

2.Data regarding the CVC/ICVC configuration should have been recorded and saved. This data must be reconfigured into the new CVC/ICVC. If this data is not available, fol- low the procedures described in the Software Configura- tion section.

If a CCN Building Supervisor or Service Tool is avail- able, the module configuration should have already been uploaded into memory. When the new module is in- stalled, the configuration can be downloaded from the computer.

Any communication wires from other chillers or CCN modules should be disconnected to prevent the new CVC/ICVC module from uploading incorrect run hours into memory.

3.To install this module, record values for the TOTAL COMPRESSOR STARTS and the COMPRESSOR ONTIME from the MAINSTAT screen on the CVC/ ICVC.

4.Power off the controls.

5.Remove the old CVC/ICVC.

6.Install the new CVC/ICVC module. Turn the control power back on.

7.The CVC/ICVC now automatically attaches to the local network device.

8.Access the MAINSTAT table and highlight the TOTAL

COMPRESSOR STARTS parameter. Press the SELECT softkey. Increase or decrease the value to match the starts

value recorded in Step 3. Press the ENTER softkey when you reach the correct value. Now, move the high- light bar to the COMPRESSOR ONTIME parameter.

Press the SELECT softkey. Increase or decrease the run hours value to match the value recorded in Step 2. Press the ENTER softkey when the correct value is reached.

9.Complete the CVC/ICVC installation. Following the in- structions in the Input Service Configurations section, page 55, input all the proper configurations such as the time, date, etc. Check the pressure transducer calibra- tions. PSIO installation is now complete.

Solid-State Starters — Troubleshooting information per- taining to the Benshaw, Inc., solid-state starter may be found in the following paragraphs and in the Carrier RediStart MICRO™ Instruction Manual supplied by the starter vendor.

Attempt to solve the problem by using the following prelim- inary checks before consulting the troubleshooting tables found in the Benshaw manual.

1.Motor terminals or starter output lugs or wire should not be touched without disconnecting the incoming power supply. The silicon control rectifiers (SCRs) although technically turned off still have AC mains potential on the output of the starter.

2.Power is present on all yellow wiring throughout the system even though the main circuit breaker in the unit is off.

With power off:

•Inspect for physical damage and signs of arcing, over- heating, etc.

•Verify the wiring to the starter is correct.

•Verify all connections in the starter are tight.

•Check the control transformer fuses.

TESTING SILICON CONTROL RECTIFIERS IN THE BENSHAW, INC., SOLID-STATE STARTERS — If an SCR is suspected of being defective, use the following procedure as part of a general troubleshooting guide.

1.Verify power is applied.

2.Verify the state of each SCR light-emitting diode (LED) on the micropower card.

NOTE: All LEDs should be lit. If any red or green side of these LEDs is not lit, the line voltage is not present or one or more SCRs has failed.

3.Check incoming power. If voltage is not present check the incoming line. If voltage is present, proceed to Steps 4 through 11.

NOTE: If after completing Steps 4 - 11 all measurements are within specified limits, the SCRs are functioning nor- mally. If after completing Steps 4 - 11 resistance measure- ments are outside the specified limits, the motor leads on the starter power lugs T1 through T6 should be removed and the steps repeated. This will identify if abnormal re- sistance measurements are being influenced by the motor windings.

4.Remove power from the starter unit.
