Curtain machines
Curtains are usually controlled by equipment called curtain machines (sometimes referred to as
winches). Curtains are opened and closed to let in more air or less air, the idea being more air cools
the building. Curtain machines use a timer and do not have a feedback potentiometer.
To connect actuators
1. Connect actuators to the control as shown below. Refer to your actuator’s installation guide for
information about its power supply requirements.
2. Calibrate the actuator. You can calibrate by pressing the CALIBRATE button, or using the
display. For more information the calibration process, and instructions for calibrating using the
display, read
Calibrating actuators
on page 39.

When routing the actuator feedback wires, do not run them in or along the same
conduit as AC-power lines.

If you are unsure of the potentiometer wiring for your actuator, read
Determining
correct actuator feedback wiring
on page 40.

If you are measuring AC power with a digital multimeter (DMM) and a limit switch
opens the circuit, the DMM measures voltage after the relay switch even if the
relay is open.
