Woodward GCP-30 Series - Pick-Up

Manual 37278B GCP-30 Series - Genset Control
© Woodward Page 133/174
Parameter 307
Delayed engine
monitoring 00s
Engine; delayed engine monitoring 1 to 99 s
Delay between reaching the firing speed and monitoring of selected alarms (e.g. oil
pressure, generator underfrequency, etc.).
Parameter 308
Firing speed
reached f >00Hz
Engine; firing speed reached 5 to 70 Hz
Setting of the firing speed: Once this firing speed has been reached, the starter is
disengaged (switched off) and the frequency controller starts governing.
Note
Accurate measurement is possible above 15 Hz, even if 5 Hz are displayed. If the
Pickup measurement has been configured to "ON", values down to 5 Hz are dis-
played.
Pick-Up
Measuring the engine speed can be performed alternatively by means of a Magnetic Pickup, the generator fre-
quency, or a tacho generator. Refer to the wiring diagram that pertains to your specific controller in ma-
nual 37239, chapter 4.
Parameter 309
Pickup input
ON
Pickup; Pickup measurement ON/OFF
ON ................ Engine speed monitoring is performed by means of a Magnetic
Pickup. Once firing speed has been achieved, the starter disengage-
ment is initiated by the MPU measurements.
OFF .............. Frequency monitoring/control is performed by means of the genera-
tor frequency measurement. Once firing speed has been achieved, the
starter disengagement is initiated by the generator frequency mea-
surements.
Parameter 310
Number of pickup
teeth 000
Pickup; number of Pickup teeth 30 to 280
Number of pulses per revolution.
Plausibility monitoring:
Plausibility monitoring is the comparison of the measured electrical frequency (de-
termined from the generator voltage) and mechanical speed (determined from the
Pickup signal). If the two frequencies are not identical, a class F1 alarm is initiated.
The plausibility monitoring is enabled by the expiration of delayed engine monitor-
ing (Parameter 307) and performed continuously whi
le the generator is operating.
Parameter 311
Gen.rated speed
0000 rpm
Pickup; rated speed at rated frequency 0 to 3,000 rpm
Number of revolutions per minute at rated frequency speed.
