7.2. Connecting a waste oil tank 23132 (2-Levels)
To achieve a proper function, that is the pump stops if the physical tank is full or if the sensor is
disconnected, the following connection should be made. The EX function switches should be set in
position I.
8. To connect analogue level sensor 23 417
To be able to use an analogue level sensor with a TSM in stand-alone use a Keypad (23401) or a LED (23404)
must be used to show tank level and a PC must be used to configure the port. The PC is not needed after
configuration is done.
The four analogue inputs on the TSM supports any standard industrial 2-lead / 4-20mA / 24VDC sensors. To
connect sensors a 2-pole connector is used.
The submergible pressure based level
sensor 23 417 is a robust sensor that
can be used with good accuracy for
tanks with a height of 1
– 5 meters. Max
height depends on density of fluid. The
measuring resolution for a TSM with a
23 417 sensor is 4 mm for water and
about 4.5 mm for mineral oil.
Connect the red wire to +24VDC and the
black wire to Sense. +24VDC and Sense
are printed on the PCB.
If the sensor cable (6.5 m) is to short to
reach the TSM it can be lengthen using
a standard 2-lead wire with copper area
of 0.5 mm2 for each lead. For this
purpose use the by-packed connection
box.
It is not necessary to use the shield to
obtain a good signal because the signal
