The calibration process is absolutely necessary for proper rotator control and consist of two parts: setting rotation
limits and calibrating the position indicator. Both calibrations are done simultaneously.
IMPORTANT: During calibration the previously defined parameters are not used. Clicking Cancel during the
calibration will abort the process and retain the old values.
Properly connect the rotator controller to the ROTOR port, refer to the previous chapter for details. Open
1.
SMD's top cover.
Select rotator that is going to be calibrated in the rotators list and click Calibrate button. Make sure that
2.
the CONTROL BOX field shows proper SMD address (local ROTATOR).
3.
Select Sensor type, ANALOG for potentiometer sensor or voltage feedback, PULSE for pulse sensor.
If your rotator uses BRAKE, set AUX relay for BRAKE
4.
function. During calibration, AUX will be activated when the
rotator moves, but will be deactivated if rotator is idle for
more than 15 sec, to prevent overheating the brake or power
supply. If your rotator uses SPEED control, set AUX for
SPEED function. During calibration AUX will be activated to
set the rotator speed to slow.
Turn rotator fully counter clockwise (CCW). If rotator turns in
5.
the opposite direction, check the "Reverse direction" box. If
your rotator does not have hardware limits, turn the rotator to
the desired maximum counter-clockwise position.
If rotator has an ANALOG sensor, adjust the OFFSET
6.
trimmer in Station Master Deluxe until the sensor value
shows 0002 (is in range 0001-0003) and click next.
If rotator has PULSE sensor, click next step.
Turn the rotator fully clockwise (CW). If your rotator does not have hardware limits, turn it to the desired
7.
maximum clockwise. If your rotator uses pulse counting, do not turn it CCW at all as this will result in an
inaccurate pulse count and effect the calibration.
If rotator has an ANALOG sensor set SCALE trimmer in Station Master Deluxe until sensor value shows
8.
1021 (between 1020-1022) and click next.
If value cannot be set with SCALE trimmer and remains unchanged, click "Reverse Sensor", and set
OFFSET trimmer until sensor value shows 0002 (between 0001-0003).
If rotator has PULSE sensor, check if sensor value is non zero, click next and skip to step 13. If sensor
value is zero or has very low number (below 20), check the sensor connection and repeat calibration.
Turn rotator fully counter clockwise (CCW) or to desired maximum CCW position.
9.
Slightly readjust OFFSET for improved accuracy until sensor value shows 0002 (between 0001-0003)
and click next.
If "Reverse Sensor" was checked in previous step, set SCALE trimmer until sensor value shows 1021 (is
in range 1020-1022) and click next.
10.
Turn rotator fully counter clockwise (CW) or to desired exact final CW position.
