Appendix
Calibration of the level measurement
If the distance of the ultrasonic sensor above the surface is
known, it will be possible make a calibration of Shuttle
® 's
level read-out.
The calibration will only have influence on the level read-out
- not on relay setpoints for pump control, alarms etc.
Note:
Because of the built-in temperature compensation,
it is important that the ultrasonic sensor has the
same temperature as the surrounding air. Leave
the sensor in the surrounding air for minimum 1
hour.
Shuttle ® reverts to normal read-out.
If the learning function has been activated, Shuttle ® will de-
activate the learning function and erase the suspicious levels
that were found last time the learning function was activated.
The learning function must therefore both be started and
reactivated again.
If the relay outputs are configured for pump control, the
relays will be deactivated, but their limit settings will not be
erased. Also, delay settings and other settings will not be
erased.
Select the desired correction with the arrow keys.
