PR: Pressure sensor

Setting of the type of pressure sensor used. This parameter enables selection of a ratiometric or current type pressure sensor. For
each type of sensor, different full scales can be selected. When a ratiometric sensor is selected (default) the input Press 1 must be
used for connection. When a 4-20mA current sensor is used, the relative screw terminals on the input terminal board must be used.
(See Collegamento del sensore di pressione par 2.2.3.1)
PR value
0 6.6 Ratiometric (0-5V)
1 6.7 Ratiometric (0-5V)
2 6.8 Ratiometric (0-5V)
3 4-20 mA
4 4-20 mA
5 4-20 mA
The setting of the pressure sensor does not depend on the pressure to be obtained, but on the sensor to be fitted on the

6.5.9 FI: Flow sensor setting
This enables setting of operation as described in Table 19.
Value
0 without flow sensor
1 single specific flow sensor (F3.00)
2 multiple specific flow sensor (F3.00)
3 manual setting for a general single pulse flow sensor
4 manual setting for a general multiple pulse flow sensor
In the case of multi inverter operation, use of multiple sensors can be specified.

Operation without flow sensor

When the setting without flow sensor is selected, the FK and FD settings are automatically disabled as these parameters are not
necessary. The parameter disabled message is indicated by an icon showing a padlock.
It is possible to choose between 2 different operating modes without flow sensor by means of the parameter FZ (see par. 6.5.12):
