3. Evaluation of the E+H-specific diagnostic command #231:
By means of this diagnostic code, the device status is displayed using a
"quality code" with four stages. The assignment of a certain device status
to a specific stage in the "quality code" takes place in the transmitter.
More information on this can be found in the Operating Instructions of
the transmitter used.
Six DIP switches can be used to specify at which stage or stages the relay
contact is triggered (see Table below).
