0400 0400 SUBMENU SENSOR
In this submenu all actual value sensors which are connected to the HYDROVAR can be
configured, (up to two transducers with current output or voltage signal output).
It is not possible to install two different transducer types because main configuration is the
same for all connected sensors. Transducers must be always the same type.

Dimension unit
Possible settings: bar, psi, m 3 /h, g/min, mH2O, ft, °C, °F, l/sec, l/min, m/sec, …, %
Chose the desired dimension unit by pressing
▲ or ▼.
By changing the DIMENSION UNIT, you have to consider changing the SENSOR RANGE
[0420] according to the new DIMENSION UNIT too!

Sensor 1
Selection of the sensor
Possible settings: - Sensor 1 - Sensor 2 - Auto
- Switch Dig1 - Switch Dig2 - Switch Dig3 - Switch Dig4
- Auto Lower - Auto Higher - (Sensor 1 – Sensor 2)
This parameter determines how the connected sensors are used and which one is active.
It is also possible to measure the difference of two connected sensors or to configure an
automatic switchover in case of a faulty sensor.
Sensor 1
Sensor 1 is constantly active.
0/4-20mA signal ……. connected to X3/2 and X3/3 (+24V)
0-10V signal ……. connected to X3/6 and X3/3 (+24V)
Sensor 2
Sensor 2 is constantly active.
0/4-20mA signal ……. connected to X3/4 and X3/3 (+24V)
0-10V signal ……. connected to X3/5 and X3/3 (+24V)
Auto Automatic switch over in case of a faulty transmitter.
Switch Dig1 Manual switching by closing digital input 1 (X3/9-10)
Switch Dig2 Manual switching by closing digital input 2 (X3/6-GND)
Switch Dig3 Manual switching by closing digital input 3 (X3/5-GND)
Switch Dig4 Manual switching by closing digital input 4 (X3/15-GND)
Auto Lower
The sensor with the lower actual value (or available sensor in case of a
faulty sensor) is used automatically
Auto Higher
The sensor with the higher actual value (or available sensor in case of a
faulty sensor) is used automatically
Sens.1 – Sens.2 The difference of both connected sensors is taken as actual value
