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 phase control
ALWAYS
ensure the phase control receives ample airflow
ALWAYS
use adequate fusing
NEVER
hold the phase control in your hand or lap when energized
NEVER
install the phase control in a place it can get wet or is exposed to the elements
NEVER
mount the phase control over a screw, bolt, rivet, seam, or other fastener
NEVER
remove the PC500X cover while the unit is in operation
NEVER
insert a screwdriver or other object under the regulator cover
NEVER
touch any exposed part of the PC1500 during operation
(LIVE HEATSINKS)
NEVER
install a switch in the DC portion of the phase control’s wiring
NEVER USE A DIGITAL FREQUENCY METER
(It
can give a false reading
!)
Functional Description
The PC1500 Series Phase Control is the result of over 20 years of engineering efforts and offers
high-demand features at a competitive price point. The PC1500 is a proven design and is
engineered to greatly simplify setup while offering extreme reliability. When properly installed, the
PC1500 Series Phase Control is designed to provide a lifetime of service.
An automatic phase control has several automated tasks it must perform in order to provide
reliable, clean, and regulated electricity. It must maintain a preset setpoint and protect both itself
and the connected load should a fault situation arise.
The PC1500 Series uses field-replaceable cartridge fuses to protect its internal circuitry should a
fault occur and the load current exceeds what the phase control is capable of delivering. It also
contains reliable circuitry that is designed to maintain a setpoint regardless of outside influences
or ambient temperature.
Due to its extreme simplicity, the PC1500 Series Phase Control is uncommonly reliable and offers
features and accuracy usually only offered by much more complicated and often much more
expensive phase controls.
