4 L.L.i .1 Lower Linear Input AI1
AI1 lower limit only for linear signals. Ex.: with input 4..20 mA this parameter takes value associated
to 4 mA. The value may be greater than the one entered on the next parameter.

u .L.i .1 Upper Linear Input AI1
AI1 upper limit only for linear signals Ex: with input 4..20 mA this parameter takes value associated
to 20 mA.The value may be lower than the one entered on the previous parameter.

P. vA.1 Potentiometer Value AI1
Selects the value of the potentiometer connected on AI1
1..150 kohm. Default: 10kohm
7
i.o.L.1 Linear Input over Limits AI1
If AI1 is a linear input, allows to the process to overpass the limits (parameters 4 and 5).

o . c A .1 Offset Calibration AI1
AI1 Offset calibration. Value added/subtracted to the process value (ex: usually correcting the
ambient temperature value).

G. ca .1 Gain Calibration AI1
Value multiplied to the process value to calibrate the working point. Ex: to correct the range from
0..1000°C showing 0..1010°C, set the parameter to -1.0
-100.0%...+100.0%, Default: 0.0.

c.FL.1 Conversion Filter AI1
ADC Filter: Number of sensor readings to calculate mean that defines process value. NB: When
readings increase, control loop speed slows down. 1...15. (Default: 10)
12
c.Fr.1 Conversion Frequency AI1
Sampling frequency of digital / analogue converter for AI1. Increasing the conversion speed will
slow down reading stability
(example: for fast transients, as the pressure, it is advisable to increase sampling frequency).
