ical) burns.
ÎIf possible, drain the process medium from all the plant sections concerned and the
valve.
ÎWear protective clothing, safety gloves and eyewear.
Risk of burn injuries due to hot or cold components and pipelines.
Depending on the process medium, valve components and pipelines may get very hot
or cold and cause burn injuries.
ÎAllow components and pipelines to cool down or heat up.
ÎWear protective clothing and safety gloves.
Damage to health relating to the REACH regulation.
If a SAMSON device contains a substance which is listed as being a substance of very
high concern on the candidate list of the REACH regulation, this circumstance is indi-
cated on the SAMSON delivery note.

ÎOnlyusetheprocessmediumspeciedforsizing.
Irreparable regulator damage caused by the regulator components being taken
apart.
The safety temperature monitor is an inseparable hydraulic unit consisting of a safety
thermostat, capillary tube and temperature sensor. If these components are dismantled
(e.g. removal of the capillary tube), the regulator will be irreparably damaged and will
nolongerbeabletofulllitsmonitoringandcontroltask.
ÎDo not dismantle the regulator.
ÎOnly perform allowed activities on the regulator.
ÎContact SAMSON's After-sales Service department before replacing spare parts.
Risk of valve damage due to contamination (e.g. solid particles) in the pipeline.
The plant operator is responsible for cleaning the pipelines in the plant.
ÎFlush the pipelines before start-up.
ÎObserve the maximum permissible pressure for valve and plant.
Risk of damage to the valve or safety temperature monitor due to excessively high
or low tightening torques.
The connection between valve and safety temperature monitor must be tightened with a
certain tightening torque.
Excessively tightened torques lead to parts wearing out quicker. Parts that are too loose
may cause leakage.

Design and principle of operation
3 Design and principle of oper-
ation
See Fig.2.
The safety temperature monitor (STM) oper-
ates according to the liquid expansion prin-
ciple. The temperature sensor (12), capillary
tube(9)andoperatingelement(8)arelled
with an expansion liquid.
The temperature-dependent change in vol-
ume of the liquid in the bulb sensor (12)
causes the piston in the operating element
(8) to move. As a result, the pin of the oper-
ating element (7) moves the plug stem (5)
with the plug (3). The temperature limit can
be adjusted by a key (10). This limit value is
indicated on the dial (11).
The safety temperature monitor closes the
valve when the temperature reaches the ad-
justed temperature limit. The safety tempera-
ture monitor resets itself automatically when
the temperature has fallen to a value of ap-
prox.5Kbelowtheadjustedlimit.
Fail-safe position
The spring mechanism in the operating ele-
ment is released when the capillary tube
breaks or when there is a leak in the sensor.
It moves the plug stem (5) with the plug (3)
over the pin (7) and closes and locks the
valve.
The adjusted limit temperature must have a
minimum temperature difference of 15K to
the set point of the temperature regulator.

Shut-off valve
Install a hand-operated shut-off valve both
upstream of the strainer and downstream of
the regulator. This allows the plant to be shut
down for cleaning and maintenance, and
when the plant is not used for longer periods
of time.
Thermometer
Install a thermometer both upstream and
downstream of the regulator to monitor the
temperatures prevailing in the plant.

Retrotting a signal transmitter
The electric signal transmitter (order no.
1690-5724)canbettedasfollows:
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
considerableambienttemperatureuctua-
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
50mm.
5.4 Electric signal transmitter
Thesafetytemperaturemonitorcanbetted
with an electric signal transmitter. The signal
transmitter contains a microswitch (max.
load10A,125V,250V)whichgenerates
a signal if the temperature limit is exceeded
or if the sensor fails (capillary tube is bro-
ken).
