The devices re vilble s sfety-temperture monitors STW (STB) nd sfety temperture limiters STB. In the event of mlfunction, the STB switches the monitored mchine to sfe operting sttus. Pnel-mounted thermostts operte ccording to the fluid expnsion principle; microswitch is used s n electricl switching element. Type Approvls/pprovl mrks (see "Technicl Dt") Type

If the temperture flls below the selected limit vlue (by the mount of the switching differentil), the switch is reset to its initil position. If the temperture on the temperture probe exceeds the set limit vlue, the electricl circuit is opened nd the microswitch is mechniclly locked. The microswitch cn be mnully unlocked once the dngerous temperture drops by pprox. 10 % of the scle rnge (pprox. 15 % with limit vlue setting > + 350 C). The switching circuit following the thermostt must comply with DIN EN 14597 nd VDE 0116. If the mesuring system is destroyed (i.e. if the expnsion fluid escpes) the pressure in the membrne of the STB nd STW (STB) drops nd permnently opens the electricl circuit. Unlocking is no longer possible. If the probe hs cooled down to temperture below pprox. -20 C, the electricl circuit is lso opened; when the temperture rises bove pprox. -20 C, the STB must be unlocked mnully using the restrt knob. The STW (STB) utomticlly restrts.
