Brief description
Thermostats are used to control and monitor thermal processes. The devices of the ATH.-SE
type series are available as temperature monitors TW, safety temperature monitors STW (STB)
and safety temperature limiters STB. In the event of a malfunction, the STB switches the mon-
itored machine line to an operational safe status.
Surface-mounting thermostats operate according to the fluid expansion principle,
a microswitch is used as an electrical switching element.
Switching function
Temperature monitor TW and safety temperature monitor STW
If the temperature exceeds the limit value set on the temperature probe, the current circuit is
opened via a snap switch. The switch is reset to its original status once the set limit value is
gone below (by the hysteresis).
Restart lock of the safety temperature limiter STB
If the temperature exceeds the limit value set on the temperature probe, the current circuit is
opened and mechanically locked.
Once the limit value is gone below by approx. ~ 10% of the temperature range, the switch can
be manually unlocked.
Use of the safety temperature monitor STW
as safety temperature limiter STB
Ensure that the switching circuit downstream of the thermostat complies to DIN EN 14597 and
VDE 0116.
Self-monitoring for the 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 di-
aphragm of the STB and STW (STB) drops and permanently opens the current circuit. Unlocking
is no longer possible.If the probe has cooled down to a temperature below approx. -20 °C, the
current circuit is opened, when the temperature rises above approx. -20 °C, the STB must be
unlocked manually first using the re-starting button. The STW (STB) automatically restarts.
