KRONOS 20
In connection with the gas mixer, the valve functions as an ideal lambda control system,
with a freely programmable lambda map in dependence of speed and load. In an ex-
tended closed-loop version it allows compensation for changes in gas quality and envi-
ronmental factors. This makes it possible to use biogas with minimal emissions.

Additional Functions
•
Engine Stop
On activation of the digital input for engine stop, the gas valve will be completely
closed in dependence of the parameter settings until the engine stops. But usually the
engine will be stopped by closing the gas shut-off valve on the gas train.
•
Overspeed Protection
Overspeed may be set in a parameter. If this overspeed is exceeded the control unit
emits an alarm and closes the gas valve.
•
Operating Hours Counter
Sums up the hours during which the engine runs (speed is recognized). In addition the
number of engine starts is registered.
