• Generous: the control is active until the deviation is less than 50 mbar. The
control is reactivated if the deviation exceeds 100 mbar.
Factory setting: Plug&Play
8.6.8 Pressure range
The parameters of the "p-Range" menu can only be set for "Smart"
type devices.
With AV-EP pressure regulators for fieldbus connection, the parameter
settings from the "p-Range" menu are overwritten by the fieldbus.
Minimum set point w
min
The device actively works (controls the pressure) within the range w
where w > p . w is therefore to be considered as an entry point.
min min min
The following settings are possible:
Value range:
6-bar devices: 0.5 ... 6 bar (1 – 87 psi)
10-bar devices: 0.5 ... 10 bar (1 – 145 psi)
Increments: 0.1 bar (1 psi)
Factory setting: 0.1 bar
The value range 0.1 ... 0.4 bar is not guaranteed.
Recommended initial value: ≥ 0.5 bar.
Beginning of pressure range p
The beginning of the pressure range p
characteristic curve and therefore the zero point of the device characteristic
curve. In most cases the following applies: p
The following settings are possible:
Value range:
6-bar devices: 0 ... 3 bar (0 – 44 psi)
10-bar devices: 0 ... 5 bar (0 – 73 psi)
Increments: 0.1 bar (1 psi)
Factory setting: 0 bar
End of pressure range p
max
The end of the pressure range p
acteristic curve.
The following settings are possible:
Value range:
6-bar devices: 1.2 ... 6 bar (17 – 87 psi)
10-bar devices: 2 ... 10 bar (29 – 145 psi)
Increments: 0.1 bar (1 psi)
Factory setting:
6-bar devices: 6 bar
10-bar devices: 10 bar
