6.6.4 Sensor configuration parameters
Parameter
number
Parameter name Unit of measurement Description
P40 Sensor selection [P1, ISP,
USP]
Analog input configuration setup:
• P1 absolute reading pressure sensor
• ISP 4–20 mA input as speed reference
• USP 0–10 V input as speed rederence
Default: P1
P41 Pressure Sensor Unit Of
Measure [BAR, PSI]
G
This parameter sets the unit of measure (BAr, PSI) for
the pressure sensor.
It affect the head view LED parameter (see Par.
6.3.4).
Default: bar.
P42 Full scale value for pressure
Sensor 1 4-20mA
[0.0-25.0BAR] / [0.0-363PSI]
G
bar/psi This parameter sets the Full Scale value of the
4-20mA pressure sensor connected to analog input
17 and 18.
Default: depending on the type of pump.
P44 Zero Pressure Auto-
Calibration
bar/psi This parameter lets the user perform the initial auto-
calibration of the pressure sensor.
It is used to compensate for the offset signal of the
sensor at zero pressure caused by the tolerance of
the sensor itself.
Procedure:
1. Access P44 when the hydraulic system is at 0
pressure (no water inside), or with the pressure
sensor disconnected from the piping: the actual
value of 0 pressure is displayed.
2. Start the auto-calibration by pressing or
(see Par. 6.2).
3. At the end of the auto-calibration, the 0 (zero)
pressure is displayed, or the “---“ (---) message, if
the sensor signal is out of the permitted tolerance.
P45 Pressure Minimum Threshold
[0-42]
G
bar/psi Setting the minimum pressure threshold.
If the system pressure falls below this threshold for
the time set in P46, a low pressure error E14 is
generated.
Default: 0 bar.
P46 Pressure Minimum Threshold
- Delay Time [1-100]
G
s Time delay setup.
This parameter sets the time delay during which the
unit remains idle with a system pressure below P45,
before generating the low pressure error E14.
Default: 2 s.
P47 Pressure Minimum Threshold
– Automatic Error Reset
[OFF, ON]
G
Enabling/disabling of automatic unit attempts in case
of low pressure error.
Default: ON.
