Retrofitting a signal transmitter
The electric signal transmitter (order no.
1690-5724) can be fitted as follows:
1. Unfasten the four screws (1) at the con-
necting part and remove the scale (2).
2. Take the ready-assembled transmitter out
of the packaging. Remove the two bolts
(5) and nuts (6). Take the switch (3) off
the scale (4).
3. Secure the scale (4) to the connecting
part using the four screws (1), ensuring
that the pointer (7) of the travel stem is
able to move in a straight line in the mid-
dle of the left window.

Galvanic corrosion due to incorrectly se
-
lected materials of the mounting parts.
On installing the sensor or thermowell, only
use similar materials (e.g. stainless steel with
stainless steel or copper together with other
copper materials).
Capillary tube
Carefully run the capillary tube (9) without
bending or twisting it. Avoid locations with
considerable ambient temperature fluctua
-
tions along the entire length of the tube.
Do not damage or shorten the capillary
tube. Roll up excess tube to form a ring. The
smallest permissible bending radius is
50 mm.
5.4 Electric signal transmitter
The safety temperature monitor can be fitted
with an electric signal transmitter. The signal
transmitter contains a microswitch (max.
load 10 A, 125 V, 250 V) which generates
a signal if the temperature limit is exceeded
or if the sensor fails (capillary tube is bro-
ken).
