UEGO
Input for UEGO sensor signal (from UEGO interface unit). It is not possible to connect UEGO sensor
directly without interface unit. Configure sensor characteristics corresponding to UEGO interface unit
output signal in IS-AIN8.
UEGO corresponding setpoints:
AFR control
:
Diff O2
,
Diff O2 del
.
Protection: Engine Slow stop (cool down) when actual UEGO value is out ±
Diff O2
for
Diff O2 del.
Protection is active when genset power is higher than
Low MAP power
.
Configure sensor characteristics with one decimal point i.e. format 10,0%.
Mixer fdb
Analog input for mixer feedback position. Mixer feedback is used for binary mixer position control only
and it is not used for mixer control via analog output (indication only). Mixer feedback sensor
characteristics must be configured in the range 0,0 to 100,0% to be the same dimension as Mixer
position output.
Logical analog values
Mixer position [ 0,0 to 100,0%]
Configure this output to IS-NT physical analog output 0 – 10V (0 – 20 mA) for mixer control.
IS-NT Mixer position output conversion to IS-NT physical analog output
Mixer feedback [ 0,0 to 100,0%]
Actual value based on Mixer fedb input.
MAP required [ 0,000 to 10,000 bar]
Final MAP required including temperature correction.
