Engine: Pickup
To configure the pickup input, the following values must be configured:
DE
EN
• Nominal speed (RPM)
• The speed measurement method – via pickup (MPU) or an output at the alternator
• Number of teeth on the flywheel detected by the magnetic pick up (MPU) or the number of pulses per
revolution of the engine.

ON / OFF
ON................ Speed monitoring of the engine is carried out using an MPU or speed
output.
OFF.............. Speed/frequency monitoring of the generator set (the engine) is
performed by measuring the frequency of the generator. There is no
MPU or sensor wired to this unit.
Nominal speed
500 to 4,000 RPM
Number of revolutions per minute of the engine at rated engine speed.
Pickup measurement from
Pickup / Sensor
Pickup .......... Speed monitoring of the engine is carried out using an MPU.
Sensor .......... Speed monitoring of the engine is carried out using the speed output
at the alternator (terminal W).

The number of pulse per revolution is configured here if a speed output at the
alternator is used. Since the alternator is usually driven by a V-belt by the engine,
the transmission ratio of the belt must be considered here. This parameter provides
two decimal digits to be able to adjust any transmission ratio.

The filter enables to filter heavily varying speed signals. This may be useful if the
speed is measured using an output at the alternator (parameter 47 configured to
"Sensor") because engine ignition timing and the elasticity of the V-belt may cause
a heavily varying speed display.
The speed display may be filtered with 8 stages. If "0" is configured here, no filter
is applied.
Note: If the filter is enabled, only the speed display is filtered. Speed monitoring
and the speed value transmitted on the bus systems are not affected by the filter and
use the measured speed data.
