Configuration for installers only
Sensor type
The sensor signal is a voltage, current or
resistance.
Resistive Resistive,
current,
voltage
Sensor power
Option for powered sensors. Smart: the sensor is
switched On only if necessary. * See below
Off
Off, On, Smart
Sensor damping
Sensor fluctuations can be damped to different
levels. The heavier the damping, the larger the
fluctuations that are damped.
Light
Light, medium , heavy
Tank type
This option allows for indicating the fluid type
contained in the tank or its filling type. Example: a
fresh water tank empties on use and a grey water
tank fills on use.

Tank volume
Enter the tank volume as specified.
The volume is expressed in the unit selected.

Calibration
This interface is calibrated by determining at
which level the tank is full and empty. The
interface calculates the tank level by interpolation.

Tank full, Tank empty
* For Smart powering, your sensor must be able to
produce a reliable signal within 100 milliseconds,
regardless the tank conditions. If you are not sure,
choose On first, calibrate and read the
corresponding AD values. Choose Smart next and
calibrate again. If the AD values compare well, your
sensor is convenient for Smart powering.
3 INSTALLATION
Insert the MasterBus cables, then connect the
sensor cables to the screw terminal 3 (if necessary) ,
4 and 5, see below. Finally connect the battery
cables (1, 2) if necessary.
