The PS-PRO also assists in analyzing any faults that
may occur in the AC mains wiring. Two green and
one red neon indicators light in a specific pattern for
normal wiring and in different patterns for various
faults. When the AC wiring is correct, both green
indicators will be lit, but not the red indicator. If
any other pattern of indicators is lit, a fault is pres-
ent. The chart next to the indicators identifies the
fault’s exact nature. Since any wiring fault presents
a potentially serious safety hazard, the assistance
of a qualified electrician should be obtained in cor-
recting the problem.

The method of initiating an ON or OFF sequence
depends on whether the unit is to be controlled
locally or remotely. If remotely, it further depends
on the type of switch or switches used (momentary
or maintained).

LOCAL CONTROL
For local control, an ON sequence is initiated
by turning the key switch to the ON position,
and an OFF sequence by turning the key switch
to REM or OFF position. The START ON-OFF
SEQUENCE pushbutton is not normally used in
local operation.

The PS-PRO provides a very high degree of power
conditioning protection for your expensive and
delicate equipment. What sets Furman’s top-of-the-
line PRO-level protection apart from that offered
by other conditioners is the quantity, quality, and
configuration of its suppression devices. These in-
clude MOV’s, gas discharge tubes, fast-blow fuses,
and high voltage inductors and capacitors. This
unique combination can safely absorb and dissipate
large spikes from nearby lightning strikes and other
sources (up to 11,000 amps across any wiring mode
— line-neutral, line-ground, or neutral-ground), as
well as highly attenuate audible high frequency
noise. Clean, filtered power is provided at all 9
outlets, even the unswitched ones.
The PS-PRO also includes special circuitry to detect
additional wiring faults, with several front panel LED
status indicators. The PS-PRO will even keep itself
from turning on, or will shut down under extreme
conditions, if the voltage falls below 80 volts or
rises above 140 volts. This feature is called “Extreme
Voltage Shutdown.” It is particularly valuable in the
entertainment industry, where equipment is fre-
quently moved to different venues, and accidental
connection to 220V is a real possibility. See pages
5-6 or more information on the various protection
features’ indicator lights.
Despite its many protective features, you should be
aware that the PS-PRO does not compensate if the
AC line voltage itself is high or low (i.e., it does not
compensate for brownout conditions). If you fre-
quently move your rack to different locations, derive
power from generators, use long extension cords,
travel internationally, or are in an area particularly
prone to brownouts, you may benefit from the
use of one of Furman’s AC Line Voltage Regulators
in addition to the PS-PRO. If you do use a voltage
regulator, run the raw power line into the regulator
