Brief description
Thermostats control and monitor thermal processes.
This thermostat is available as temperature controller TR, temperature monitor TW (type
602030), safety temperature monitor STW (STB), or safety temperature limiter STB (type
602031).
The panel-mounted thermostat operates according to the fluid expansion principle. The electrical
switching element is a snap-action switch.
The panel-mounted thermostat is RoHS-compliant and cadmium-free.
Switching functions
Temperature controller TR and Temperature monitor TW
If the temperature on the temperature probe exceeds the setpoint value, the electrical circuit is
opened or closed by a microswitch. If the temperature falls below the selected setpoint value (by
the switching differential), the microswitch is reset to its initial position.
Restart lock at safety temperature limiter STB
If the temperature at the temperature sensor exceeds the set limit value, the electrical circuit is
opened and the microswitch is mechanically locked. After falling below the limit value by approx.
10 % of the temperature range (approx. 15 % of the limit value setting > +350 °C), the switch can
be unlocked manually.
Use of the safety temperature monitor STW as a safety temperature limiter STB
The circuitry used with the thermostat must comply with DIN EN 14597 and VDE 0631.
Self-monitoring for safety temperature limiter STB and safety temperature monitor 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. Un-
locking is then no longer possible.
When the STW (STB) and STB sensors cools down to the negative temperature range, the cir-
cuit 1 to 2 opens, but must be unlocked manually by the restart knob when the temperature rises.
The STW (STB) restarts automatically.
