Tank-Monitor VTM

3.2. Electrical connection
The voltage measurement to indicate 2
battery voltages is carried out for the first
battery via the + terminal (12/24V) of the
supply
voltage.
The
second
voltage
measurement is carried out on the Batt.2+
terminal.
Up to four tanks can be monitored
simultaneously.
However, if fewer tanks are monitored, the first
fuel gauge will be connected starting at port TG
1 (for example, with 2 tankers, only ports TG 1
and TG 2 will be used).
Resistive sensors (e.g., TGT / TGW) and active
tank sensors (e.g., TDS pressure probes) may be
connected in mixed form.
The connection is made according to the
adjacent diagram
A DFS flow sensor can only be connected to DFS
(DFS + / Minus / DFS S)!
ATTENTION:
If the power supply (red line) of the ultrasonic
sensor or the pressure sensor TDS does not
take place via the VTM, but directly via the DC
on-board network, the supply line must be
fused with a 1A fuse!
The minus lines of the tank sensors must be
connected to the minus (-) terminal to avoid
incorrect measurements.
