Error status 1 "active high"
The signal at the switching output is permanently voltage-carrying. The MCS has
detected an error.
This error occurs also when operation voltage is switched off and measurement
voltage is switched on.

Error status 2 "active low"
The signal at the switching output is permanently voltage-carrying. The MCS has not
detected an error.
This error occurs also when operation voltage is switched off and measurement
voltage is switched on.
Only a superordinate controller can differentiate between this error signal and
normal operation without detection of a particle. Evaluate the signal duration and the
behavior of the two switching outputs S1 and S2 separately.
