1 Page 1/11 urface-mounted Thermostat ATH series pecial features turdy case (protection type IP 54)) Microswitch elf-monitoring (TB/TW (TB)) in the event of a pressure drop afety cut-out (TB/TW (TB)) Tested according to IN EN Brief description Thermostats control and monitor thermal processes. Instruments of the ATH series are available as temperature controllers TR, temperature monitors TW, safety temperature monitors TW (TB), and safety temperature limiters TB. When malfunctions occur, the TB places the system being monitored in a safe operating status. urface-mounted thermostats operate according to the fluid expansion principle a microswitch is used as an electrical switching element. ATHs-1 witching function Temperature controller TR and temperature monitor TW If the temperature on the temperature probe exceeds the setpoint value, the microswitch is activated by the transmission mechanics and the electrical circuit is opened or closed. If the temperature falls below the selected setpoint value (by the amount of the switching ), the microswitch is reset to its initial position. ATHf- Restart lock on the safety temperature limiter TB 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 (approx. 15 with a limit value setting > ). Using the safety temperature monitor TW (TB) as a safety temperature limiter TB The circuit following the thermostat must comply with IN EN and VE elf-monitoring on the safety temperature limiter TB and the safety temperature monitor TW (TB) If the measuring system is destroyed (i.e. if the expansion fluid escapes) the pressure in the membrane of the TB and TW (TB) drops and permanently opens the electrical circuit. Unlocking is then no longer possible. The electrical circuit opens when cooling the probe of TW (TB) and TB down to the negative temperature, but it then closes again if the temperature rises. The TB must be unlocked manually if the minimum probe temperature is exceeded. The TW (TB) unlocks itself automatically Approvals
