3. Read the resulting temperature at the
thermometer installed in the plant (after
approx. 5 min.).
4.
When the limit temperature is still too
low:
slowly turn the key (10) at the safety tem-
perature monitor clockwise (
) to in-
crease the limit until the temperature at
the thermometer reaches and remains at
the limit temperature.
After the temperature reaches the limit
temperature:
turn the rotary knob clockwise (
) three
more times.
5. To calibrate the limit reading to the limit
temperature, perform a correction (see
section 6.3).
6. When a control thermostat is mounted,
readjust it to the required set point.
7 Servicing
The safety temperature monitor does not re-
quire any maintenance. Nevertheless, it is
subject to natural wear, particularly at the
soldering.
Risk of personal injury due to residual pro-
cess medium in the valve.
While exchanging the safety temperature
monitor, residual process medium can es-
cape and, depending on its properties, may
lead to personal injury, e.g. (chemical)
burns.
WARNING
!
Wear protective clothing, safety gloves, and
eyewear.
Risk of burn injuries due to hot or cold com
-
ponents and pipeline.
Valve components and the pipeline may be
-
come very hot or cold. Risk of burn injuries.
−
Allow components and pipelines to cool
down or heat up.
−
Wear protective clothing and safety gloves.
Risk of damage to the valve or safety tem-
perature 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 tight
-
ened torques lead to parts wearing out
quicker. Parts that are too loose may cause
leakage.
Observe the specified tightening torques.
The safety temperature monitor was checked
by SAMSON before it left the factory.
−
Certain test results certified by SAMSON
lose their validity when the safety tempera
-
ture monitor is opened.
−
The certification according to
DIN EN 14597 loses its validity when the
safety temperature monitor is opened.
