Caution:
Read this Installation
Manual carefully.
Warning:
Do not use digital equipment to read voltage, Hz or amperage
during this installation. Use only Analog sensing equipment! Failure to do so may
result in damage to equipment or in personal injury! Make sure that all setup is done
off line. Always wear eye protection and never hold the regulator in your hand when
energized.
The XR500B is a Universal Voltage Regulator that can be configured several different
ways to fit differing applications. Before selecting a wiring configuration for the
regulator, you must know certain pieces of information about the generator and exciter
to be successful in determining the correct hookup for the regulator. Show below is a
guide to determine the correct connection of the regulator:
•
Exciter field resistance is more than 40 ohms and exciter full load voltage is
rated at 125vdc or less. (Use connection A)
•
Exciter field resistance is more than 21 ohms and exciter full load voltage is
rated at 63vdc or less. (Use connection B)
•
Exciter field resistance is more than 10 ohms and exciter full load voltage is
rated at 32vdc or less. (Use connection C)

If this generator is going to operate at a speed lower than 50/60 Hz, a
disconnect or switch should be placed in series from the generator stator
to terminal #1 and #2 on the XR500B.
For 480vac, either use a
transformer with a 240vac
secondary or center tap the
generator windings. At T7 and
T8.
