Eclipse Rotary Actuator Instruction Manual 904-7/24/06

Warning
Local regulations may require guards
and/or warnings when connecting the
actuator to a component with linkage
that could cause nger pinching. The
actuator stall torque is at least 3.9 n-m
(35 lb-in).
Caution:
Prevent water from condensation owing into
the actuator housing through the wiring con-
duits. Keep conduits oriented such that gravity
will cause water to ow away from the actua-
tor or provide a watertight seal in the conduit
near the actuator.

Warning
Do not attempt to mechanically force
the PRA6 shaft to rotate
1.
Determine if the buttery valve (BV) has
unrestricted full rotation or if it has physical
stops that limit rotation to a specic angle.
Also determine the minimum position, rota-
tion direction to open, and maximum open
position for the BV. The Programmable Rotary
Actuator (PRA) is shipped in its minimum po-
sition, clockwise to open, and the part number
shows whether the stroke has been factory
set to either 90 degrees or 75 degrees (see
Table 2 of the Appendix). These settings can
be changed through the keypad. Compare the
BV requirements to the PRA.
Caution:
Electrical ttings are factory installed to main-
tain seal and must not be altered. Use only
factory supplied ttings assembled as shown
on Data 904.
