Operation
6.1.1
Adjusting the tempera-
ture limit without using
a heating bath
If another temperature limit is to be adjusted
without using a heating bath, turn the black
plastic ring according to the scale (see Ta-
ble 9). To do this, proceed as follows:
1. If a sealing wire (19) exists, remove it.
2.
Adjust the new limit value (see Table 9)
at the set point adjuster (8).
Turn clockwise (
) to reduce the
temperature
Turn counterclockwise (
) to increase
the temperature
3.
Lead-seal the safety temperature limiter
(optional).
4. Make sure the minimum temperature dif-
ference is observed for the TR/STL.
Note:
Before adjusting the limit value, the
safety temperature limiter must be
mounted on the valve.
The setting is continuously adjustable. A turn
corresponds to approx. 3.2 K or 3.9 K de
-
pending on the limit range (see Table 9).
6.1.2
Adjusting the tempera-
ture limit using a
heating bath
If the temperature limit of the safety tempera-
ture limiter is to be adjusted precisely using a
heating bath or a deviation in the limit value
exists, proceed as follows:
1. Remove the sensor from the thermowell.
2.
When a Type 2430 Control Thermostat
or double adapter is used, unscrew it
from the safety temperature limiter.
3. Remove the safety temperature limiter
from the valve.
4. If a sealing wire (19) is used, remove it.
5. Turn the set point adjuster (8) counter-
clockwise (
) to adjust the maximum
possible limit value (see section 6.1).
6. Immerse the sensor of the safety tem-
perature limiter completely (for at least
five minutes) into the heating bath with
the correct temperature.
7. Check whether the safety temperature
limiter has been triggered.
