C.DESCRIPTION OF PARAMETERS

1.D1: setpoint differential. The switching differential (hysteresis) can be set with positive value (make on rise) or with negative value (make on fall). See parameter “HC1”.

2.LS1: lower set. This is the lower limit below which the user cannot change the setpoint; normally set at the lowest value recommended for the sensor.

3HS1: higher set. Similar to “LS1”, however setting an upper limit for the setpoint.

4.od: output delay. This provides a delay selection for the outputs in applications where noise may cause brief erroneous signals from the sensor to the controller. Factory set at “0”.

5.Lci: lower current input (for EWPC 902/R, EWPC 902/P and EWPC 902/T with current input only). Read-out corresponding to 4 mA input signal (factory set at 20 %R.H for EWPC 902/R).

6.Hci: high current input (for EWPC 902/R, EWPC 902/P and EWPC 902/T with current input only). Read-out corresponding to 20 mA input signal (factory set at 100 %R.H for EWPC 902/R).

7.CAL: CALibration. This offers an adjustment up or down of the read-out, if needed. Factory set at “0”.
