Binary Outputs
Error +
The output is low impedance if an error has occurred.
Serious damages can occur. The engine should be
switched off by the master control. To exit the error
state, the error needs to be acknowledged (refer to
Acknowledging Faults
on page 107).

Overtemp. +
The output is low impedance if a too high exhaust gas
temperature has been measured before or after the
catalytic converter.

The output is low impedance when the supply voltage is
present and the emission controller is ready for
operation.

O
The output has a low impedance if the VariSCR emission
controller is in a state in which the SCR control does not
yet function or only functions to a limited extent (e.g.
if the catalyst temperature is too low).
