Installation and Operation Instructions
rev. 01/23/13
Rectification Settings
The AC to DC rectification may be set to
either full wave or half wave by attaching
the supplied clip to terminal block J2.
Attach the clip to J2 for full wave. Do not
use the clip for half wave. Note: If the
VC3000 is ordered FW the clip is installed
on J2. If the VC3000 is ordered HW, the
clip is taped to the bottom of the metal
plate.
When multiple devices (such as
controllers, actuators, and the VC3000)
are connected to one transformer, the full
wave/half wave rectification of all devices
must match. For example, if the controllers
being used are half wave and connected
to the same transformer that supplies the
voltage converter board, then do not use
the clip on J2. Always remove 24 VAC
power before changing the clip position.
