PS-PRO E II / PE II - POWER CONDITIONER / SEQUENCER PS-PRO E II / PE II - POWER CONDITIONER / SEQUENCER
REAR PANEL LIGHT SWITCH: All Series II units
feature a rear rack BNC socket which will accept
any 12 VAC (0.5A) gooseneck lamp assembly, (such
as the Furman GN-LED or GN-I). Simply slide the
BNC plug over the socket and rotate clockwise until
the connector snaps into the locked position. The
rear rack lamp can be powered on or off with the
rear light power switch located on the far left of the
front panel.
START ON/OFF SEQUENCE: This pushbutton
switch is used only when the key lock switch is in
REM po si tion and the PS-PRO E II / PE II is in Mo-
men tary Mode. It then acts the same as any other
remote mo men tary switch that may be con nect ed to
the rear panel terminal strip. If the switched outlets
are on, pushing it begins an OFF se quence. If they
are off, pushing it begins an ON se quence. Do not
use this switch when in Main tained Mode.
PROTECTION OK: This LED is normally on when
the power to the PS-PRO E II / PE II’s outlets is
switched on. It mon i tors the integrity of the protection
de vic es and re ports if the pro tec tion is com pro mised.
If an ex treme ly large spike is en coun tered that ex-
ceeds the PS-PRO E II / PE II’s capacity, the main
group of input pro tec tors will blow an in ter nal fuse,
caus ing the in di ca tor to go out. If this LED is not lit
when the power switch is on, full pro tec tion is not
functioning. Spike protection may still exist, but will
have a re duced ca pac i ty to absorb cur rent. If this
LED is not lit, please con tact the Furman Ser vice
Department.
EXTREME VOLTAGE SHUTDOWN: This LED in di -
ca tor is nor mal ly off. It mon i tors a hazard com mon
in the en ter tain ment in dus try—wiring faults—for
example, ac ci den tal connection to 380V.
The PS-PRO E II / PE II sens es voltages that are so
high or low that op er a tion would be impossible (under
150V or over 280V) and shuts the power down be fore
dam age can oc cur. Upon initially applying pow er to
the PS-PRO E II / PE II, this in di ca tor will be lit if the
unit is re ceiv ing below 150 volts or more than 280volts,
and pow er will not be applied to the PS-PRO E II / PE
II’s outlets. If the unit has been op er at ing with an ac-
cept able input voltage and then the volt age goes out
of the ac cept able range, the PS-PRO E II / PE II will
shut down power to all of its switched out lets si mul -
ta neous ly, without observing the OFF delay cycle,
and this LED will be gin fl ashing. When power returns
to within the acceptable range, the PS-PRO E II / PE
II will ob serve its ON delays as it re turns power to its
switched outlets, and this LED will go out.
NOTE: If the mains power is below 150 volts and has
caused the PS-PRO E II / PE II to re move power
from its out lets, the PS-PRO E II / PE II will not
restore power to its out lets until the mains voltage
is more than 175 volts. If the mains power is above
280 volts and has caused the PS-PRO E II / PE II
to remove power from its out lets, the PS-PRO E II
/ PE II will not restore pow er to its out lets until the
mains voltage is less than 265 volts. The reason for
this is to prevent the power from os cil lat ing on and
off in marginal con di tions.
DELAY ADJUST: This screwdriver-ad just able trim-
pot al lows you to set the total turn-on/turn-off delay
time from 1 to 60 seconds, as ex plained on page 6.
The trimpot ad justs both the on delay and off delay
times si mul ta neous ly. Turn the trim pot clock wise to
in crease the on and off de lay times; turn the trimpot
coun ter clock wise to de crease the delay times.
POWER STATUS (DELAY) LEDs: One green LED
is pro vid ed for each of the three delay stages.

PS-PRO PE II shown here (PS-PRO E II has an extra IEC outlet
on the front in lieu of the IEC OUTLET CIRCUIT BREAKER) Each LED lights when power is applied to its cor-
re spond ing du plex outlet on the rear panel. All three
LEDs then re main lit until pow er is removed. Dur ing
the power-down delay cy cle, each LED goes off as
power to its corresponding out let is re moved. In ad-
di tion, the Delay 1 LED fl ash es if a remote switch
(or the stored state) is OFF.
UNSWITCHED OUTLET: This convenient outlet
pro vides power at all times when the PS-PRO E
II / PE II is plugged in and op er at ing under normal
power con di tions.
CIRCUIT BREAKER: The overall ca pac i ty of the
PS-PRO E II / PE II is 16 amps. Should the combined
steady-state current drawn by all devices plugged
into the unit at any time exceed 16 amps, the circuit
break er will trip, cutting off power to your rack. If this
occurs, re duce the load by un plug ging one or more
units from the PS-PRO E II / PE II, and reset it. You
can reset the circuit break er by simply toggling the
power button. However, be cause it is a thermal type,
you may have to wait a few moments after it trips for
it to cool down before it will allow you to reset it.
ON/REM/OFF SWITCH: When turned to the ON po-
sition, this key lock switch initiates an ON se quence,
applying power to the PS-PRO E II / PE II’s switched
outlets. When turned to the OFF po si tion, it be gins
an OFF se quence. In the REM position, the PS-
PRO E II / PE II will ac cept on/off com mands from
a remote switch or switch es that may be con nect ed
to the rear pan el ter mi nals.
UNSWITCHED OUT LETS: The PS-PRO E II / PE II
rear panel provides clean, fi ltered power to this pair
of unswitched outlets, adjacent to the power cord.
SWITCHED (DELAYED) OUTLETS: The PS-PRO E
II / PE II rear panel provides three pairs of switched
out lets, widely spaced to allow use of equipment with
plug- in (wall wart) trans form ers. These switched
outlet pairs are labeled Delay 1, Delay 2 and Delay
3. After the front panel switch is thrown to ON, Delay
1 outlets receive power in stant ly, Delay 2 outlets re-
ceive pow er 1-30 sec onds later and Delay 3 out lets
receive power 1-30 sec onds after Delay 2 outlets
are powered. When thrown to OFF, the se quence is
reversed, with Delay 3 losing power instantly, Delay
2 out lets los ing pow er 1-30 sec onds later and Delay
1 out lets losing power 1-30 seconds after Delay 2
out lets are shut down. The delay intervals may be
altered with the screw driv er-ad just able Delay Ad just
con trol on the front panel.
TERMINAL STRIP: Allows one or more switch es
to be connected to turn the PS-PRO E II / PE II on
and off from a remote location. Two, and sometimes
three, wires are needed to install a remote switch
(see “Main tained Mode”, page 6.) If a four-con duc tor
cable is used, an LED may be installed at the remote
end to indicate that the power is on.
