Micro switch! elf-monitoring (TB/TW)! afety cut-out (TB/TW)! separate measuring an switching systems ATHs- Brief escription Thermostats are use to control an monitor thermal processes. urface-mounting ouble thermostats of the ATH type series consist of two separate measuring an switching systems. The evices are available as temperature controllers TR, temperature monitors TW, safety temperature monitors TW (TB) an safety temperature limiters TB. In the event of a malfunction, the TB switches the monitore machine line to an operationally safe status. urface-mounting ouble thermostats operate accoring to the flui expansion principle, a micro switch serves as an electrical switching element. witching function Temperature controller TR an temperature monitor TW If the temperature excees the set point value set on the temperature probe, the micro switch will be trippe by the transmission mechanics an the current circuit opene or close. The micro switch is reset to its original status once the set point value set is gone below (by the hysteresis). ATHf-70 Restart lock for the safety temperature limiter TB If the temperature excees the limit value set on the temperature probe, the current circuit is opene an the micro switch mechanically locke. The micro switch can be manually unlocke, once the angerous temperature rops by approx. 0 % of the scale range (approx. 5% with a limit value setting " #350 C). Use of the safety temperature monitor TW as a safety temperature limiter TB Ensure that the switching circuit ownstream of the thermostat complies to DIN EN 4597 an VDE 06. elf-monitoring for the safety temperature limiter TB an safety temperature monitor TW (TB) If the measuring system is estroye, i.e. if the expansion flui escapes, the pressure in the iaphragm of the TB an TW (TB) rops an permanently opens the current circuit. Unlocking is no longer possible. If the probe has coole own to a temperature below approx. -0 C, the current circuit is opene, when the temperature rises above approx. -0, the TB must be unlocke manually first using the re-starting button. The TW (TB) automatically restarts. Approvals/approval marks (see Technical Data) The eclarations of conformity can be foun in the internet uner: Proucts or they can be sent on request.
