6.Restore control system power (the LID displays, COM- MUNICATION FAILURE at the bottom of the screen).

7.Access the SERVICE menu. Highlight and select the ATTACH TO NETWORK DEVICE screen. Press

the ATTACH softkey. (The LID displays, UPLOAD- ING TABLES. PLEASE WAIT; then, COMMUNICA- TION FAILURE.) Press the EXIT softkey.

8.Turn off control power.

9.Mount the new module in the unit control box using a long-shaft Phillips screwdriver and the screw saved in Step 4 on page 98. Make sure that the green grounding wire is reinstalled along with the mounting screw.

10.Connect the LID communication wires (CCN bus) and the power wires. If CCN wiring has been attached to the CCN bus, disconnect the wires. Attach the sensor bus plug and the input and output plugs.

11.Carefully check all wiring connections before restoring power.

12.Restore control power and verify that the red and green LEDs on the PSIO are functioning properly.

13.The LID should indicate AVAILABLE MEMORY and a value. This value should start to decrease. (If it does not, check the LID wiring to the PSIO; ensure connec- tion to the proper plug.) The bottom of the screen dis- plays, UPLOADING TABLES, PLEASE WAIT.

14.After the PSIO tables have been uploaded into the LID, access the STATUS01 screen. Move the highlight bar to the TOTAL COMPRESSOR STARTS line. Press the

SELECT softkey and then, using the INCREASE or

DECREASE softkeys, change the value until it is the

same as the value from the old module. Press the ENTER softkey to save this value.

15.Move the highlight bar to the COMPRESSOR ONTIME line. Press the SELECT softkey and the, us-

ing the INCREASE or DECREASE softkeys, change this value until it matches the old module run hours. Press the SELECT softkey to save this value.

16.Change the address of the PSIO In the CONTROLLER IDENTIFICATION table back to its previous value. Write the address on the PSIO.

17.Use the con®guration sheets (pages CL-3 to CL-11) to input set point, con®guration, and schedule information into the PSIO. The TIME AND DATE table from the SERVICE menu must also be set. A Building Supervi- sor terminal can be used to download the old con®gu- ration into the PSIO.

18.Access the CONTROL TEST table and perform the con- trol tests to verify all that all tested functions are work- ing properly.

If the software version has been updated, a CCN down- load of the con®guration will not be allowed. Con®gure the PSIO by hand, and upload the PSIO into the net- work using the ATTACH TO NETWORK DEVICE screen.

19.Restore the chiller to normal operation; calibrate the mo- tor amps.
