Parameters CF10 ÷ CF11
Indicate the correction values to add to or subtract from the analogue inputs; by means of this parameter it is
possible to calibrate the temperature/pressure value read by the device. The value given by the instrument reading
“AIxx analogue input differential" will be used by the regulator connected to that probe and will be displayed on-
screen. If the input is configured as a digital input, the corresponding correction parameter must be set to 0
(otherwise the digital input will not function correctly).
Parameters CF14 ÷ CF15
Indicate the logical meaning of the analogue inputs. If the input is configured as a digital input, refer to parameters
CF23..CF26.
Value Description
0 Probe disabled
1 Inlet regulation probe *
2 Outlet regulation probe **
3 Not Used
* If CF02=4-20mA, 0-10V, 0-5V then CF14 cannot be set to 2 or 3.
** If CF03=4-20mA, 0-10V, 0-5V then CF15 cannot be set to 1.
2) DIGITAL INPUTS (DI1, DI2, DI3 DI4 and DI5)
The EWCM32x74 device has 5 digital inputs for potential-free contacts which are configurable by means of user
parameters. If necessary the analogue inputs may also be configured as digital inputs.
Parameter Description
CF16…CF20 DI1 …DI5 digital input configuration
CF23 …CF26* AI ...AI4 analogue input configuration if configured as digital input
* Set = 0 if AI1 is NOT configured as DI.
