Wanco Two-Bearing Belt-Drive Generators
This is not a do-it-yourself project and should only be done by a
certified electrician or electrical contractor.
1. Remove the top cover of the control box.
2. Before adjusting the voltage, establish the proper speed using a
frequency meter:
■
For 60-hertz models, the generator shaft is turning at 1800
RPM when the frequency meter reads 60 Hz.
■
For 50-hertz models, the generator shaft is turning at 1500
RPM when the frequency meter reads 50 Hz.
3. The generator has several automatic voltage regulators. Locate the
Phillips adjusting screw marked “
VOLTS
” in small print. DO NOT touch
any other adjusting screws.
4. With no load on the generator, and the generator operating at
either 60 hertz and 1800 RPM, or 50 hertz and 1500 RPM, turn the
“
VOLTS
” adjusting screw very slowly, wait a few seconds, then
monitor the voltage from one line (hot wire) to neutral (or center
tap on 240V delta connections). The voltage will increase or
decrease depending on the direction you turn the screw.
5. When you have established the proper voltage, stop the generator
and reinstall the top cover of the control box.
3.1.5 Installation options
Belt and pulleys
The most common installation connects the generator and engine
using a belt and pulleys, available from industrial supply sources.
■
All engines vibrate and shake while running. The generator must
move with the engine or the belt that connects them will slip. The
engine and generator must therefore be mounted on a common
base, such as a steel plate. Installing rubber mounts on the bottom
of the baseplate prevents it from shifting during operation. See
Figure 3-2.
CAUTION
Improper installation can result in equipment damage and
severe injury.
To prevent the engine and generator from lifting off the baseplate,
ensure they are both securely fastened.
