ADJUSTMENT/ CALIBRATION OF LEVEL PROBES
7.3.1 LASER PROBE SETTING 0295131, 24V cc Out NO and NC (1 threshold)
* To obtain a correct setting bring the lock ring to maximum setting value and then down to desire value.
On the pump is placed a label that shows the wiring diagram and setting values. The pump is normally equipped with pre setting
sensor to "L" thresholds (minimum level). Whereas other thresholds: MM (absolute maximum level), M (absolute level), LL
(absolute minimum level), can be set
Attention you can only set one thresholds at a time
7.3.3 Procedure for calibrating the laser probe 24V cc Out 4÷20mA/2 NO (4 thresholds)
The laser probe possesses a representative and programming display mounted on board. It is possible to operate in analogue
mode (with signal from 4 to 20 mA) or in digital mode (two outputs and four intervention thresholds).
We attach a table showing the calibration parameters for the laser probe.
