Position Sensor Settings
A position sensor is mainly used to verify the correct movement of a curtain, ridge vent, chimney
damper or inlet that it is attached to. Its main purpose is to create an alarm situation if the reading
from the position sensor does not match the attached device’s calculated position from the controller.
A secondary benefit of the position sensor is the ability of the controller to use the position sensor reading to
correct the attached device’s position. After the inlet device has moved, if the calculated position and the position
sensor reading do not match, the controller will move the inlet device again to correct the position. ALL of the
following have to be true in order for the controller to use the position sensor in this way.
1. The position sensor has to be attached to a curtain, ridge vent, chimney damper or inlet.
2. The position sensor has to be calibrated so the device and position sensor settings match.
3. The “Enable Position Alarm” has to be set to YES.
4. The difference between the device’s calculated position and the position sensor reading has to be within the
percentage set in the “Percent OUT of Position to alarm” setting.
5. The device’s calculated position and the position sensor reading have to be more than 3 seconds of travel
time apart.
If ALL the above are true, then if the controller finds that the device’s calculated position and the position sensor’s
reading are different, the controller will move the device again until the calculated position and position sensor
reading are within 3 seconds of time. If less than 3 seconds of travel time is required to make the position’s match,
the controller will not move the device again. If the positions are greater than the percentage to alarm, the control
-
ler will create an alarm and stop using the position sensor until the alarm is cleared. Once the alarm is cleared, the
controller will assume the position sensor reading shows the device’s correct position, and will move the device to
its calculated position, if required.
Two conditions will cause the position sensor to be completely ignored by the controller.
1. If the position sensor is in an alarm state.
2. If the “Enable Position Alarm” setting is set to NO.
