LED status messages
In the event of impermissible temperature increase within the Katherm QE, for example
by increasing the temperature within the Katherm QE, an integrated two-stage safety
switch guarantees that the unit is properly switched off. At a temperature of 80°C within
the Katherm QE, the heating element is disabled.
A roll-up grille temperature of 45 Kelvin above the room temperature is maintained in
accordance with IEC EN 60335-2-30. The triggering of the safety temperature monitor
can be signalled via a potential-free fault alert contact. After rectifying the cause of the
fault, the fault message is acknowledged by resetting the supply voltage.
The speed of the EC tangential fan is also monitored.
Should no speed pulses of the EC tangential fan be generated because of the motor
coming to a standstill, the electric heating element is disabled.
