Figure 3. Only Acceptable Position for NEMA Type 3R
Rating Using ASK75.1U Weather Shield.
The GCA actuator is UL listed to meet NEMA Type 3R
requirements (a degree of protection against rain, sleet,
and damage from external ice formation) when installed
with the Weather Shield (product number ASK75.1U) and
outdoor-rated conduit fittings. Actuator must be in the
vertical position.
Prerequisites
CAUTION:
Do not turn the 3 mm hex key against the
direction of the arrow.
Item Number: 129-404 Rev. JA
NOTE: Actuator is shipped from the factory with 5°
preload. When power is applied to the actuator,
the preload is released. To manually release the
preload, insert the 3 mm hex key in the override
opening and turn the key in the direction of the
arrow. See Manual Override.

Figure 10. The Angular Rotation is Adjustable Between 0°
and 90° at 5 Degree Intervals.
Make sure the actuator is in the "0" (fail-safe) position when making
this adjustment. If making the adjustment before the actuator is in
service, take into account the factory set 5° preload. To release the
preload, see To Release Manual Override or Preload section.
Other settings
1.
Insert the 3 mm hex key in the override opening,
(Step 1).
For adjustment of auxiliary switches and span/offset options see the
Technical Instructions listed under References.
2.
Turn the key in the direction of the arrow until you
reach the desired degree of opening, (Step 2).
Tandem Operation
3.
Hold the key in place, (Step 3).
Two GCA Actuators with 2-position or floating control signal are
mounted to the same side of the damper shaft using the ASK73.1
Tandem Mounting Bracket as shown in Figure 11.
4.
Insert a small flat-blade screwdriver into the gear
train lock pin. Turn the screwdriver in the same
direction as the arrow until you hear a click or meet
slight resistance, (Step 4).
Two GCA Actuators with a modulating control signal are mounted to
the same side of the damper shaft using the ASK73.2U Tandem
Mounting Bracket also as shown in Figure 11.
CAUTION:
When engaging the gear train lock pin,
cautiously turn only about 5 degrees
until you hear a click or meet slight
resistance. Turning too far will strip the
lock pin.
5.
Remove the key or keep it in place, (Step 5).
1.
Insert the 3 mm hex key in the override opening,
(Step 6).
2.
Turn the key only a short distance in the direction of
the arrow, (Step 7).
3.
Remove the key, (Step 8).
The actuator will return to "0" (fail-safe) position.
NOTE: Applying power and sending a control
signal will release manual override.

To release manual override or preload
Figure 11. Tandem Mounting on Same Side of Damper Shaft.
NOTE: For applications requiring single damper shaft operation by
up to four GCA modulating control signal actuators mounted
on each side of the damper shaft, use the GCA15x Series
Actuators with Master/Slave mode operation selected. See
Figure 12.
(See Wiring Diagrams for GCA15x Series master/slave operation
wiring instructions.) (See OpenAir™ Spring Return Electric Damper
Actuator Modulating Control Technical Instructions document
155-173P25 for complete tandem mounting instructions.)

Use earth ground isolating step-down Class 2
transformers. Do not use autotransformers.
NOTE:
The maximum rating for a Class 2 step-down
transformer is 100 VA. Determine the supply
transformer rating by summing the VA ratings
of all actuators and all other components
used. It is recommended that not more than
80% of the transformer VA be utilized. The
GCA actuator consumes 8 VA or less.
