Electrical Connections; Commissioning And Maintenance; Releasing The Transducer; Instruments Admissions - OHIO SEMITRONICS DVT A Série Mode D'emploi

Simply clip the device onto the top-hat rail (EN 50 022) (see
Fig. 1).
Fig. 1. Mounting on top-hat rail 35 × 15 or 35 × 7.5 mm.

5. Electrical connections

Connect the electrical conductors acc. to the instructions
on type label.
Make sure that all input cables are not
live (potential-free) when making the
connections!
Also note that, ...
... the data required to carry out the prescribed
measurement must correspond to those
marked on the nameplate of the DVT-XXXA
( measuring input,
see Fig. 3)!
... the resistance in the output circuit
– may not overrange the value
R max. [kΩ] ≤
ext
(I = current output value)
AN
in the case of current output
– and not underrange the value
R min. ≥ 200 kΩ
ext
in the case of voltage output
... the measurement output cables should be
twisted pairs and run as far as possible away
from heavy current cables!
In all other respects, observe all local regulations
when selecting the type of electrical cable and
installing them!

6. Commissioning and maintenance

Switch on the measuring input. It is possible during the
operation to disconnect the output line and to connect a
check instrument, e.g. for a functional test.
No maintenance is required.

7. Releasing the transducer

Release the transducer from a top-hat rail as shown in
Fig. 4.
