OWN-ADV 01/12
For the magnetic pickup and generator output options you must select the rated frequency and rated speed.
The WaveNet uses these values together to calculate the engine speed from the magnetic input or generator
output.
The rated speed is the speed (in revolutions per minute, RPM) the engine runs at when producing power.
The rated frequency is usually either 50Hz or 60Hz. It is the frequency of the generator output when producing
power. For a magnetic input the rated frequency is determined by the number of teeth on the fl ywheel and is
calculated by:
Rated frequency = (Number of teeth x Rated Speed) / 60
For the generator output option the rated frequency is normally the frequency of the generator: 50Hz or 60Hz.
5.2.1 RATED SPEED
5.3.1 AC FREQUENCY
The AC Frequency, AC Voltage, and AC Current menus allow the measurement and display of the
AC voltage, current, and frequency from the generator.
In the AC Frequency menu, warnings and failures can be triggered for frequencies under and/or over
settable thresholds. The DisconnectFreq setting is used by the WaveNet controller as a backup to the
speed input. If the speed input is not detected, the controller checks the DisconnectFreq settings. If
the measured frequency is greater than this setting then the engine will be considered running.
5.3 GENERATOR (AC VOLTAGE / CURRENT / FREQUENCY) SETUP
5.3.2 AC VOLTAGE
The user can enter under voltage, over voltage, and over current settings for four different voltage con fi gurations.
This allows the WaveNet to be used on multiple generator types without having to con fi gure each WaveNet or it
allows a single generator to support multiple voltage con fi gurations without having to go into the menu system.
Each voltage group supports a different generator con fi guration:
1. Voltage Group 1 – Single Phase (two or three wire)
2. Voltage Group 2 – Three Phase (Delta or Hi Wye)
3. Voltage Group 3 – Three Phase Hi Wye (Hi Wye center tapped)
4. Voltage Group 4 – Three Phase (three or four wire delta)
Voltage Group 1 has an option (the Group 1 Setting under the AC Voltage menu) for two wire (Hot
and Neutral) or three wire (A, B, Neutral) single phase. If two wire single phase is selected the
WaveNet display is
fi xed to L-N.
Voltage Group 2 can be used for 3 wire delta and non-center-tapped Hi Wye con fi gurations. Voltage
Group 3 is the same as Voltage Group 2. There is a Group 3 Setting that can be enabled and is
normally used for center tapped Hi Wye applications where the voltage displayed on the controller
is double the actual measured voltage. Voltage Group 3 with the Group 3 Setting enabled is also
useful in non-center-tapped Hi Wye and 4-wire Delta applications where the user wishes to measure
a voltage greater than 600VAC – the maximum voltage the WaveNet supports. In this case the user
can use a 2:1 potential transformer (PT) to step down the voltage to the WaveNet and still have the
WaveNet display the correct voltage.
