If only the PSIO slave or DSIO module indicate commu- nication failure, check the affected module for proper seat- ing. If the condition persists even though connections are correct, replace the module as described in the following section.

Module Replacement (PSIO, DSIO) Ð The PSIO master module controls the standard unit functions, the PSIO slave module controls many optional functions, and the DSIO module controls electric heat and/or DX cooling. If the mod- ule LEDs are not blinking and the unit or features associated with the module do not work, the module may need to be replaced. Before replacing an inoperative module, check to ensure that:

·The PIC control box power is on

·Power at the processor module is between 18 and 24 vac

·No fuses are blown

·All connections are ®rmly in place

If all of the preceding conditions exist, and the module LEDs are not blinking, the module needs to be replaced.

Before replacing a processor (PSIO) module, store the con- ®guration data from the old module on hard copy. The new processor module can be precon®gured or con®gured in the ®eld.

After obtaining a new module, ®eld-replace the inopera- tive module as follows:

1.Turn off all power to the fan motor starter and PIC con- trol box.

To avoid electrical shock and equipment damage, always disconnect all power to the control box be- fore replacing PIC modules.

2.Open the control box door.

3.Refer to Fig. 5-7 for control box component arrange- ments. Disengage all connectors from the module.

4.Use a screwdriver to remove the mounting screw securing the module to the control box. Remove the module.

5.Install the replacement module and replace the mount- ing screw.

6.Reinstall all connectors. Verify that each connector is in the correct location.

7.Turn on the power to the PIC control box and motor starter.

8.If you are replacing a PSIO master module that is not precon®gured, use the local interface device (HSIO) or Building Supervisor to reset the date and time and change the module's default settings. The original PSIO master module was factory con®gured to match the unit in which it was shipped. A replacement PSIO master mod-

ule must have the Factory Con®guration ( ) de- faults changed in the ®eld to match the con®guration of the unit in which it is being installed. Other settings may also need to be recon®gured to match the unit con- ®guration and/or the original module's settings.

9.Perform the Initial Check, run the Quick Test, and verify that the unit is operating correctly as described in the Start-Up section on page 103.

10.Close the PIC control box door.
