a)
Usually water; other fluids only if non-combustible even within the temperature range of an individual fault.
b) The temperature control media must have a fire point of ≥ 65 °C.
c)
The overheat protection can, for instance, can be realized using a suitable fill level sensor or a suitable temper-
ature limiter.
d) Optional at the choice of the manufacturer.
Mechanical overtemperature protection
Only temperature control units with a heater are fitted with a mechanical overtemperature protec-
tion. Set the overtemperature protection as described on page 35 in section »Setting the over-
temperature (OT) protection« .
Low level protection
A mechanical float is used for level monitoring. In the bath vessel, a floating body, which is guided in
a device, floats on the surface of the thermal fluid. Depending on the level of the thermal fluid, the
float device signals the electronics a state of good (in case of sufficient filling) or a state of bad (in
case of insufficient filling). The functionality of the float switch is checked at regular intervals during
continuous operation.
