Troubleshooting

troubleshooting the VMA1615/1630 controller. Table 7
provides some additional troubleshooting information for
possible problems.
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 VMA 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.
