Calibrating the Inlet/Tunnel Door
To ensure that air circulation is carried out in the most efficient manner and according to the
specifications, inlets must be positioned (opened) accurately. If used a potentiometer can control the
opening and closing with a high degree of precision.
However when there is no potentiometer, positioning accuracy tends to degrade after the inlets go
through several opening and closing cycles. The following section describes how to recalibrate the inlets,
using a potentiometer or without a potentiometer.
During installation, the user enables auto-calibration in digital output inlets. Calibration automatically
takes place after the number of inlet movements equals the number of movements required to start
calibration.
Only one inlet or tunnel curtain can be calibrated at a time.
