Actuator Install Instructions

VA9208-Bxx-x Series On/Off Electric Spring Return Valve Actuators Installation Instructions 9
See Figure 19 and Figure 20 to wire the applicable
VA9208-Bxx-3 Series model.
Using Conduit
All VA9208 Series Actuators accept 3/8 in. (10 mm)
trade size flexible metal conduit.
1. Feed the actuator cables through the field supplied
conduit.
2. Push the conduit into the holes in the actuator and
secure it with the supplied 10-32 x 9/16 in. screws,
as illustrated in Figure 21. The product label marks
the position of holes for the screws. Drive the
screws through the product label in the marked
positions. Drive the screwhead flush with the plate
to secure the conduit.
Setup and Adjustments
Auxiliary Switch (VA9208-xxC-3 Models)
The VA9208-xxC-3 models include two integral
auxiliary switches with a switch adjuster accessible on
either face of the actuator (Figure 20). The factory
setting for Auxiliary Switch No. 1 is 83% closing, and
the nominal setting for Auxiliary Switch No. 2 is 10%
opening (relative to the 0 to 100% rotation range as
printed on the product label). See the Technical
Specifications table for the auxiliary switch ratings.

IMPORTANT: Careful workmanship is required to
secure flexible metal conduit. Cut the conduit end
perpendicular to its axis. Insert the cut end into the
bottom of the holes in the actuator and hold the
conduit in place while securing it with the screws
provided. Check a completed installation by pulling
on the conduit to ensure its retention.
!
WARNING: Risk of Electric Shock and
Property Damage.
Insulate and secure each unused wire
lead before applying power to the
actuator. Failure to insulate and secure
each unused wire lead may result in
property damage, electric shock, and
severe personal injury or death.
