Troubleshooting

Table 7 provides LED status indicator information for troubleshooting the FX-PCV18 controller.

Note:

If you experience short circuits in the 24 VAC power supply causing protective devices

such as breakers or fuses to trip, make sure that the power connections on the VMA are not

reversed. The most common cause of this problem is when the 24 VAC power supply on the

PCV is reversed but not reversed on a connected secondary device. Improper wiring of this

power terminal may cause a short circuit across the 24 VAC power supply on -1 models.

Repair information

If the FX-PCV18 Series controller fails to operate within its specifications, replace the unit. For a

replacement unit, contact the nearest Johnson Controls representative.
