Basler Electric BE300PM - Manual (Page 3)

System Startup
Notes
Use an average-reading voltmeter for all voltage
readings.
Perform the steps under Preliminary Setup prior to
System Startup.
1. Start the prime mover and bring it up to rated speed.
Generator voltage should build up.
2. Slowly adjust the BE300PM Voltage control until the
generator voltage reaches the nominal level.
If used, the remote voltage adjust rheostat is now
capable of adjusting generator output voltage.
If the voltage does not build up to the rated level,
check the fuse and the generator output for excessive
load or a short circuit.
3. Apply and remove the generator load to verify stability.
If the generator responds too slowly or hunts
(oscillates), check the generator output for excessive
load or a short-circuit. Adjust the controller’s Stability
control with no load applied.
4. Check regulation under normal operating conditions. If
the regulation is poor:
a. Verify that the prime mover is operating at rated
speed.
b. Verify that the voltmeter is connected to the same
point as the controller sensing.
c. Use an average-sensing voltmeter (not an rms-
sensing voltmeter).
d. Verify that underfrequency is not in effect.
5. Verify the corner frequency setting by slowly reducing
the generator frequency until the generator output
voltage just starts to decrease.
If adjustment of the corner frequency is required:
a. Rotate the Underfrequency control fully
counterclockwise.
b. Reduce the generator frequency from nominal
(either 50 Hz or 60 Hz) to the desired corner
frequency.
c. Slowly adjust the Underfrequency control
clockwise until the generator output voltage just
starts to decrease.
