Introduction and Functional Description
Caution:
Read This Installation
Manual Carefully and Entirely!
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!
ALWAYS
perform all setup procedures off-line
ALWAYS
wear eye protection
ALWAYS
strip wire insulation properly or use insulated connectors
ALWAYS
use analog metering equipment when setting up the regulator
ALWAYS
ensure the voltage regulator receives ample airflow
ALWAYS
use adequate fusing
NEVER
hold the voltage regulator in your hand or lap when energized
NEVER
install the voltage regulator in a place it can be exposed to the elements or
moisture
NEVER
mount the voltage regulator over a screw, bolt, rivet, seam, or other fastener
NEVER
touch any exposed part of the XC14/XC15 during operation
NEVER
install a switch in the DC portion of the voltage regulator’s wiring
NEVER USE A DIGITAL FREQUENCY METER
(
It
can give a false reading
!)
Functional Description
The XC14 and XC15 Voltage regulators are the result of over 30 years of engineering efforts and offers
high-demand features at a competitive price point. The XC14/XC15 is a time and field-proven design,
based upon the Power-Tronics XR8 and SEM250A, and is engineered to greatly simplify setup while
offering extreme reliability. When properly installed, the XC14 and XC15 Voltage regulators are designed
to provide a lifetime of service.
A Generator voltage regulator has several automated tasks it must perform in order to provide reliable,
clean, and regulated electricity. It must build-up the generator, regulate the terminal voltage within its
design specifications, and protect both itself and the generator should a fault situation arise.
The XC14 Voltage regulator is designed to replace older obsolete voltage regulators or rotating exciters
with a minimum of connections and a minimum of required installation space. It contains internal field-
replaceable fusing and internal DC field noise suppression. The XC15 adds an internal battery flashing
circuit for guaranteed buildup on generators with low residual voltage.
Due to its extreme simplicity, the XC14 and XC15 Voltage regulators are uncommonly reliable and offer
features and regulation accuracy usually only offered by much more complicated and often much more
expensive voltage regulators.
