Assembly and operating manual
Plug-in module DTM-1
The plug-in module DTM-1 is an interface module
that can be retrofitted and provides an analogue
voltage output.
It can be used with the level gauges
SmartBox ® 1, 2, 3 and 4 for connecting to
control/regulatory/acquisition systems such as in a
building management system.
The output signal is a standardised 0-5 V voltage
signal.
The tank design, tank size, and tank geometry are taken into account according to the
settings on the level gauge.
The following context is applicable:
Example: For a 25,000 litres underground tank, the digital indicator displays 5,000 litres.
This value corresponds to 20% of the volume. Accordingly, the plug-in module DTM-1 then
provides a signal of 1.0 V at its 2-pole output terminal.
ASSEMBLY AND ELECTRICAL INSTALLATION
In order to avoid interferences, it is recommendable to use a screened 2-lead cable (e.g.
LiYCY 2 x 0.5mm²).
The plug-in module DTM-1 is inserted into the free slot of the level gauge SmartBox
On the level gauge SmartBox
• switch off the mains / supply voltage (230V)
• loosen and remove the front panel
• loosen the screw on the spacer bolt
• insert plug-in module DTM-1 (terminals 1 2)
and secure it to the spacer bolt using the
screw
• use the free drilled hole (self-sealing
grommet) to insert the cable into the housing
• connect the cable to the terminals 1 (+) and
2 (–) on the plug-in module
• connect the cable to a suitable input
(0 - 5 V) of the control / regulatory
/ acquisition system – observe the polarity
• switch on the mains / supply voltage (230V)

Danger to life due to electric shock!
Electric shock from touching live parts.
Before opening the housing, ensure that the equipment is free of all
voltage.
Only place under tension after ending all work.
