Caution!
The erroneous connection of a voltage
source of just around 7 V (or around 2 V
when connected to the wrong pole) can
damage the positioner.
In general, it is not necessary to connect the
positioner to a bonding conductor. Should
this be required, however, this conductor
can be connected inside the device.
For operation of the limit switches in Type
3730-11/-13/-18 Positioners, switching
amplifiers which comply with
EN 60947-5-6 must be connected to termi-
nals 41/42 and 51/52 in the output circuit.
If the positioner is to be installed in hazard-
ous areas, the relevant regulations must be
observed.
Refer to Fig. 10 for the terminal assignment.
Note!
The minimum permissible reference variable
should not fall below 3.7 mA.
