Technical data
Switching function
Control ranges and temperature probes
Capillary and temperature probe
Safety temperature monitor
STW If the temperature on the temperature probe exceeds the set limit value, the electrical circuit is opened
by a snap-action switch. If the temperature falls below the selected limit value
(by the amount of the switching differential), the switch is reset to its initial position.
Restart lock of the safety
temperature limiter STB If the temperature on the temperature probe exceeds the set limit value, the electrical circuit is opened and the
microswitch is mechanically locked.
The microswitch can be manually unlocked once the dangerous temperature drops by approx. 10 % of the
scale range (approx. 15 % with a limit value setting > + 350 °C).
Use of the safety
temperature monitor STW
as a safety temperature
limiter STB The switching circuit following the thermostat must comply with DIN EN 14597 and VDE 0116.
Self-monitoring for the
safety temperature limiter
STB and safety temperature
limiter STW (STB) If the measuring system is destroyed (i.e. if the expansion fluid escapes) the pressure in the membrane of the
STB and STW (STB) drops and permanently opens the electrical circuit. Unlocking is no longer possible.
If the probe has cooled down to a temperature below approx. -20 °C, the electrical circuit is also opened;
when the temperature rises above approx. -20 °C, the STB must be unlocked manually using the restart knob.
The STW (STB) automatically restarts.
