IMPORTANT: During calibration the previously defined parameters are not used. Clicking Cancel during the
calibration will abort the process and retain the old values.
Select the rotator to be calibrated in the rotators list of the RF boxes tab and click Calibrate button. Make
1.
sure that the CONTROL BOX field shows proper module address (uLINK ROTATOR).
Select Sensor type, ANALOG for potentiometer sensor or voltage feedback, PULSE for pulse sensor.
2.
If your rotator uses BRAKE, set AUX relay for BRAKE function. During calibration AUX will be activated
3.
when the rotator moves, but will be deactivated if rotator is idle for more than 15 sec, to prevent
overheating the brake solenoid 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).
4.
5.
If rotator has an ANALOG sensor, verify the sensor value. The value should be as set during previous
CCW limit settings procedure (002). Click next.
If the rotator has PULSE sensor, click next step.
Turn the rotator fully clockwise (CW). If your rotator uses pulse counting, do not turn it CCW even for a
6.
bit, as this will result in an inaccurate pulse count and effect the calibration.
7.
If the rotator has an ANALOG sensor verify the sensor value. The value should be as set during
previous, CW limit settings procedure (1021). Click next.
If rotator has PULSE sensor, check if sensor value is non zero, click next and skip to step 11. If sensor
value is zero or has very low number (below 20), check the sensor connection and repeat calibration.
Turn the rotator fully counter clockwise (CCW) or to desired maximum CCW position. Click next.
8.
Turn rotator fully counter clockwise (CW) or to desired exact final CW position. Click next.
9.
10.
The span of the rotator has now been calibrated. To calibrate the absolute azimuth, it is necessary to
enter two points as far apart as possible but preferable at least 30 degrees from the limits on each end of
the rotation.
Start with the rotator at the CW limit and turn the rotator counter clockwise (CCW), at least 30 deg from
11.
the clockwise limit. Enter the azimuth of the rotator as accurately as possible into the entry field.
Turn rotator at least 90 degrees further counter clockwise (CCW), but not within 30 degrees of the
12.
counter clockwise limit. Enter the angle through which you turned rotator counter clock wise from
previous calibration point as accurately as possible.
If you have multi-turn rotator and you turned the rotator more than 360 deg, you must enter cumulative
angle value. For example, if you turned rotator exactly one and half turns counter clockwise, enter 540
deg (180+360).
Click Finish. The new calibration values are automatically stored to the particular uLINK ROTATOR module.
