42 PHLOX II Ignition Control System
7 Sensor configuration
In all HEINZMANN control units there is a clear distinction between analogue or PWM in-
puts on the one hand and sensors on the other. This means that engine or application control is
determined by the current values read by the sensors, but where those sensors take their val-
ues from is configured separately.
7.1 Sensor overview
Sensors are required to measure set values, pressures, etc., and to execute functions
depending on these quantities. The following table provides an overview:
2900 IgnitionTimingOffset
Offset on the common base
ignition timing
2901 Ignition Energy Offset
Offset on the common
ignition energy setpoint
Ignition energy setpoint offset
Calculation of the engine power based
on the manifold pressure
Speed- and load-dependant ignition
timing maps

7.2 Configuration of sensors
Sensors and setpoint adjusters supply an analogue signal (current or voltage) or a PWM
signal. It is also possible to measure this signal somewhere else and have it transmitted to
the control via CAN bus. The firmware determines which possibilities are available for se-
lection. HZM-CAN customer module communication is integrated in the PHLOX II basis
software. Other CAN protocols may only be implemented on request.
