Troubleshooting
Table 8 provides LED status indicator information for troubleshooting the PCV1617 and PCV1632
controllers. Table 7 provides some additional troubleshooting information for possible problems.
Note:
If you experience short circuits in the 24 VAC power supply that cause protective devices
such as breakers or fuses to trip, make sure that the power connections on the PCV are not
reversed. The most common cause of this problem is when the 24 VAC power supply on the
PCV is reversed but it is not reversed on a connected secondary device. Improper wiring of this
power terminal may cause a short circuit across the 24 VAC power supply.
