5.4 Electric signal transmitter
The safety temperature limiter can be deliv-
ered with an electric signal transmitter (20)
already fitted. The signal transmitter contains
a microswitch (max. load 10 A, 125 V,
250 V) which generates a signal if the tem
-
perature limit is exceeded or if the sensor
fails (capillary tube is broken).
Wire the microswitch according to Fig. 4.

5.5 Start-up
Risk of burn injuries due to hot or cold com -
ponents and pipelines.
Depending on the process medium, valve
components and pipelines may get very hot
or cold and cause burn injuries.
−
Allow components and pipelines to cool
down or heat up.
−
Wear protective clothing and safety gloves.
Malfunction and damage due to adverse
weather conditions (temperature, humidity).
Do not install the safety temperature limiter
outdoors or in rooms prone to frost. If such a
location cannot be avoided, protect the reg -
ulator against freezing up if the process me-
dium flowing through the valve can freeze
up. Either heat the regulator or remove it
from the plant and completely drain the re-
sidual medium.
