2 System Description
PHLOX II Ignition Control System 5
2.5 Applications
Lean-burn engines
Lambda 1 engines
Stationary engines and vehicles
Engines with fixed and variable speed
Fuels: propane, natural gas, sewage gas, landfill gas,
carburetted hydrogen vapour
Fuels with variable gas quality
2.6 Additional functions
Engine stop, switch off ignition
Overspeed protection
Overspeed may be set in a parameter. If this overspeed is exceeded the control unit
sounds an alarm and switches off the ignition.
Engine hours counter
Displays the total number of hours during which the engine runs (speed is recognised).
Additionally, the number of engine starts is registered.
Error diagnosis and error messages
In case of sensor error, an alarm is sounded and, if necessary, the system goes into
emergency operation or closes the valve, thereby stopping the engine. Internal errors are
also recognised and are stored in the same way as all other errors. All errors can be ex-
tracted with an external, handheld programmer or, if the communications software is in-
stalled and a cable available, read out to a PC / laptop computer.
Communication
Serial interface for the HEINZMANN communications programme DcDesk 2000 or for
a handheld programmer (HEINZMANN communications cable required).
A CAN interface is available for communication with other HEINZMANN control units
and, if adequately configured, allows communication with external devices such as SPS.
In this way, the system may be integrated flexibly into a comprehensive engine man-
agement solution.
Optional misfire detection
As an option, expanded software for misfire detection is available.
