Procedure
Connect signal Input to wires 1 & 3.
Connect signal output (if used) to
wires 1 & 4.
Connect 24 VAC/VDC power to
Wires 1 & 2.
Check power wiring. Correct any
problems. Note 1
Turn reversing switch to the correct
position. Make sure the switch is
turned all the way left or right. Press
“Override Button” all the way down
and release.
Make sure the control signal positive
(+) is connected to Wire No 3 and
control signal negative (-) is connect-
ed to wire No. 1. Most control prob-
lems are caused by reversing these
two wires. Verify that the reversing
switch is all the way CCW or CW.
Disconnect signal input from Wires
No. 1 & 3.
Check input signal with a digital volt
meter (DVM). Make sure the input is
within the range of the actuator. For
(-SR) actuators this is 2 to 10 VDC or
4 to 20 mA (with 500
Ω
resistor).
Disconnect power from Wire No. 2.
Reconnect signal input to Wires No.
1 & 3.
Reconnect power to Wire No. 2.
Actuator does not drive
Actuator works properly. Test
controller by following controller
manufacturer's instructions.
Expected Response
Actuator drives to the “No
Signal” position (usually closed),
then to the “Maximum Signal”
position (usually open) then to
the “Control Signal” position.
Power supply rating should be
≥
the total power requirement of
the actuator(s). Minimum volt-
age of 19.2 VAC or 21.6 VDC.
Actuator drives to the “No
Signal” position (usually closed),
then to the “Maximum Signal”
position (usually open) then to
the “Control Signal” position.
Drives to “Control Signal”
position.
Actuator drives to the “No
Signal” position.
Input voltage or current should
be ±1% of what controller's
adjustment or programming
indicate.
Actuator drives to the “No
Signal” position (usually closed),
then to the “Maximum Signal”
position (usually open) then to
the “Control Signal” position.
Defective actuator.

Note 1 Check that the transformer(s) are sized properly.
• If a common transformer is used, make sure that polarity is observed on the secondary. This means connect all No. 1
wires to one leg of the transformer and all No. 2 wires to the other leg of the transformer.
• If multiple transformers are used with one control signal, make sure all No. 1 wires are tied together and tied to control
signal negative (-).
• Controllers and actuators must have separate 24 VAC/VDC power sources.
