SENSOR
In this submenu all actual value sensors which are connected to the HYDROVAR can be congured, (up to
two transducers with current output or voltage signal output).
Two different transducer types can not be used because the conguration is the same for all connected
sensors. Transducers must be always the same type.

Selection of the sensor
Sensor 1
Possible settings: - Sensor 1 - Sensor 2 - Auto
- Switch Dig 1 - Switch Dig 2 - Switch Dig 3 - Switch Dig 4
- 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 congure an automatic switchover in case of a
faulty sensor.
Sensor 1 is constantly active.
Sensor 1 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 is constantly active.
Sensor 2 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 transducer.
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 between connected sensors is taken as actual value
