In the event of any faults, the safety temperature limiter
model SB15 puts the system into a safe operating condition.
The shifting disk, which is arranged on the pointer shaft,
actuates the switching operation at the micro switch when
reaching the non-adjustable switch point or in case of
measuring line breakage and locks the current status.
A reset is possible with a tool only after a temperature
decrease by approx. 3 % of the scale range, if there is no
measuring line breakage.
