  • Page 30: Analog Outputs

    12 ANALOG OUTPUTS This IPE50 has an analog output (0/10V or/and 4/20mA) which is automatically calibrated for the higher value (10V or 20mA) of the max capacity selected in rAnGE 1.These outputs correspond to the displayed value. You must adjust this output through the step AoMAX and AoZEr (see step after) It works only on a positive display if the step SiGn = PoSit (if the display is negative, the output will be the minimum value set at Ao ZEr step), It works only on a negative display if the step SiGn = nEGAt (if the display is positive, the output will be the minimum value set Ao ZEr step).

  • Page 31: Error Messages

    13 ERROR MESSAGES While using the indicator, it is possible to incur in the following errors: MESSAGE DESCRIPTION Analog/digital convertor doesn't work. Check the wiring of the loadcells. Measure the signal ADC Err output of the loadcells between the pins + and - sig, the tension must not exceed 15mV. It is displayed if one tries to calibrate a point without first having confirmed the number of PREC.
