Mode of Operation/Level Setting
The relay is controlled by
mechanical triggering, e.g.
microswitch, reed relay, limit
switch etc. (examples 1 and
2), or by electronic trigger-
ing, e.g. inductive or capaci-
tive sensors (NAMUR/DIN
19234) (examples 3 and 4).
Examples 1 and 3
The relay operates when the
number of R.P.M. exceeds
the set value.

The relay releases when the
number of R.P.M. is less than
the set value. See hysteresis.
Example 2 and 4
By interconnecting pins 8
and 11 the relay function is
inverted, i.e. the relay releas-
es when the number of
R.P.M. exceeds the set
value.
The relay operates when the
number of R.P.M. is less than

Instrument connection
A moving-coil instrument
with a scale calibrated in
R.P.M. can be connected to
the SM 155. The instrument
has 1 mA full scale deflec-
tion.
The relay generates max. 8.2
