Chapter 11: Air Inlets
Total open Enter the exact time that is required to reach the
actuator’s maximum limit switch. The controller will
limit the opening of the inlet according to this param-
eter value. *This parameter is accessible if the air
inlet uses a timer.
Under Run Open Time (for timer-based inlets only) When a timer ends, it may take a few seconds for
the actuator to actually stop moving. For this
reason, the controller can switch off the actuator’s
motor slightly before its time for the actuator to
reach its exact moving time without exceeding it.
This parameter ranges from 0 to 3 seconds.*This
parameter is only shown if the inlet uses a timer and
it is only accessible with the factory password.
Calibrating the Inlets
If the inlet uses a potentiometer, the inlet’s actuator must be calibrated. This calibration indicates the mini-
mum and maximum positions of the actuator. The minimum calibrated position is a 0% opening and the
maximum calibrated position is 100%.
Before You Begin
Tip
For more accurate results, make sure at least 12 inches (30 cm) separates the minimum actuator’s posi-
tion from its maximum position.
1. Using the menu select arrow keys, navigate to Inlet→Stage Opening .
This menu is accessible if an inlet is enabled.
2. Calibrate the minimum position. Proceed as follows:
a. Close the inlet to its minimum position using the Close switch.
b. Once the inlet is closed, set the manual control switch to Off to stop the actuator.
NOTE: This parameter is only accessible if the inlet uses a potentiometer.
3. Once the minimum position is calibrated, set the minimum parameter onscreen to Yes .
The word Save is displayed for 5 seconds onscreen and the minimum position is saved.
4. Calibrate the maximum position. Proceed as follws:
a. Open the inlet to its maximum position using the Open switch.
b. Once the inlet is fully open, set the manual control switch to Off to stop the actuator.
5. Now that the maximum position is calibrated, set the maximum parameter onscreen to Yes .
The word Save is displayed for 5 seconds onscreen and the minimum position is saved.
6. Set the manual control switch back to the “Auto” position to enable the automatic control of the inlet.
