3.3. INSTALLATION AND CONNECTION
Please install the TCM in a visible place, so that it can be read off at any time. The necessary installation
cutout is 88 x 88mm, the necessary minimum depth is 40mm.
The TCM supervises up to four tanks at the same time. If you have less sensors, start connecting the first
sensor at terminal TG 1 ( if you`re using two, connect them to TG 1 and TG 2 and so on)
You can use both passive (resistance) and active (ultrasonic) sensors at the same time. For the
connection have a look at the connection diagramms.
The flow sensor DFS has to be connected to terminal TG1 (if you`re using 2 flow sensors DFS,
terminal TG1 and TG2)!
If you want to use tank sensors with an output of 4-20mA or 0-10V you need a hardware-adaption at
our company. Please ask.
The power supply of the TCM is either directly from the battery or over a power distribution panel. Use a cable
1,5mm² cross section which has to be fused (1A).
The display is lit when you press a button or you can connect the terminal “Light” to a switch and switch it
on/off manually.
ATTENTION:
If the power supply of an ultrasonic sensor is
connected directly to the on board DC system,
not through the tankmonitor, this connection
wire has to be fused by an 1A fuse!
