6. Unit Description
All units fulfill the requirements of safety class 3 according to
DIN 12876 and are thus suitable for unsupervised continu-
ous operation.
The circulator pump motor is protected against thermal over-
loading. All temperature sensors are permanently monitored
according to break or short circuit. The cooling machine is
integrated into the general safety circuit.
6.1 Safety features
The comprehensive safety system is designed on the princi-
ple of the concept of the “single fault” (EN 61010). This as-
sumes that two separate faults do not occur simultaneously.
This system therefore offers protection against
one
(single)
fault. This one fault will effectively occur automatically ...
