PID ref. off.
rEO
Used to adjust the process range. Should be
calculated by the user:
-999 to 999
0
Process min - Min feedback
rEO =
x 999
Max feedback - Min feedback
(in customer units)
PID Ref.gain
PrG
Used to adjust the sensor range to match the
-999 to 999
process range. Should be calculated by the user:
PrG =
999
Process max - Process min
x 999
Max feedback - Min feedback
Process max: process value to be set when the signal is maximum (10 V, 20 mA) on the analog input selected for
the PID setpoint. Example: 12 bar for 10 V on 0-10 V input.
Process min: process value to be set when the signal is minimum (0 V, 0 mA, 4 mA) on the analog input
selected for the PID setpoint. Example: 5 bar for 0 V on 0-10 V input.
Process max.
Adjustment range
ENGLISH
Process max and Process min correspond to the customer’s adjustment range in customer units.
Example: set between 5 bar and 12 bar.
PID setpoint
10 V
20 mA
0V
0 mA
4 mA
Process min.
Signal range
Note:
The reference value and the feedback value should always be positive, even if a bipolar analog input is used,
for example AI1 or AI3 (-10 V, +10 V). Negative values are not taken into consideration.
