Calibrating inlet actuators
After you configure relays for inlet actuators, you need to calibrate the actuators. Calibrating the actuator
lets the control know the position of the actuator when it is fully extended and fully retracted. Supra Touch
uses the limits to define the range of motion it uses to position the inlets. The limits tell the control how
much to adjust when you want the inlets open 25 percent, for example.
During calibration, the actuator opens, pauses, and then closes. If the actuator is operating properly, the
inlet should open completely and then close completely. After closing completely, the actuators should
position according to the temperature and default settings.

Before calibrating actuators, make sure the limit switches are set and the cable and
counter weights can move freely.

If calibration stops after closing the first time or fails to position properly, the feedback
signal is not connected correctly. Verify the potentiometer wiring. For more information,
read
Determining correct actuator feedback wiring
on page 78.

Because cables can stretch and equipment can come out of alignment, we recommend
you reset the limit switches and calibrate your actuators at least once each year.
To calibrate inlet actuators
1. At the Status screen, press the widget for the actuator you want to calibrate.
2. Press
Calibrate
.
3. Press
Yes
to start calibration or
No
to cancel.
If you started calibration, the actuator should open all the way and then close all the way. If calibration is
successful, the actuator will move into position according to its settings.
Configuring relays for air curtains
Air curtains use relays to switch blowers on to inflate and off to deflate air bags. An air curtain can have
from two to six air bags. Each air bag requires a separate relay.
