8.8.5 Tab: Output Options
Settings made in this tab influence the signals of the analog and binary outputs. Please refer to
the section
Functional Description on page 13 for more information on the limits you can set
here.
Ignition reduction limit
Enter the limiting value beyond which the engine is considered to be knocking. If the value is
exceeded, the binary output
ENGINE KNOCKING is activated and the values assigned to the
timing reduction are altered.
Immediate stop limit
Enter the limiting value beyond which the binary output TRIP is activated. This causes the engine
to shut down if properly wired.
Decrease ramp
Enter the value for the
Decrease ramp
. The value specifies the rate at which the timing reduction
signal (analog outputs) is disabled as soon as knocking decreases below the Ignition reduction
limit .
Timing reduction gain
Enter the value for the Timing reduction gain . This value influences the rate at which the timing
reduction signal (analog outputs) is amplified when knocking is detected. This rate equals the
mathematical product of the set value and the knocking intensity.
Maximum output value
Enter the value which the timing reduction signal (analog outputs) should be limited to. This
setting only takes effect if the checkbox
Enable max. output setting is activated.
Delay after load reduction
Enter the delay with which the timing reduction signal is to be reduced when the knocking value
falls again below the
Ignition reduction limit due to a load reduction.
Reverse analog output
Activate the checkbox to reverse the signal of the analog outputs. A maximum level then
indicates no knocking and vice versa.
