REaR PaNEl lIgHT SWITCH: All Series II
units feature a rear rack BNC socket which will
accept any 12 VAC (0.5A) gooseneck lamp as-
sembly, (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 position and the PS-PRO II is in Mo-
mentary Mode. It then acts the same as any
other remote momentary switch that may be
connected to the rear panel terminal strip. If the
switched outlets are on, pushing it begins an
OFF sequence. If they are off, pushing it begins
an ON sequence. Do not use this switch when
in Maintained Mode.
PROTECTION OK: This LED is normally on
when the power to the PS-PRO II’s outlets is
switched on. It monitors the integrity of the pro-
tection devices and reports if the protection is
compromised. If an extremely large spike is en-
countered that exceeds the PS-PRO II’s capac-
ity, the main group of input protectors will blow
an internal fuse, causing the indicator to go out.
If this LED is not lit when the power switch is on,
full protection is not functioning. Spike protection
may still exist, but will have a reduced capacity
to absorb current. If this LED is not lit, please
contact the Furman Service Department.
EXTREmE VOlTagE SHuTDOWN: This LED
indicator is normally off. It monitors a hazard
common in the entertainment industry—wiring
faults—for example, accidental connection to
220V.
The PS-PRO II senses voltages that are so high or
low that operation would be impossible (under 80V
or over 140V) and shuts the power down before
damage can occur. Upon initially applying power
to the PS-PRO II, this indicator will be lit if the unit
is receiving below 80 volts or more than 140 volts,
and power will not be applied to the PS-PRO II’s
outlets. If the unit has been operating with an ac-
ceptable input voltage and then the voltage goes
out of the acceptable range, the PS-PRO II will shut
down power to all of its switched outlets simulta-
neously, without observing the OFF delay cycle,
and this LED will begin flashing. When power re-
turns to within the acceptable range, the PS-PRO
II will observe its ON delays as it returns power to
its switched outlets, and this LED will go out.
NOTE: If the mains power is below 80 volts and
has caused the PS-PRO II to remove power
from its outlets, the PS-PRO II will not restore
power to its outlets until the mains voltage is
more than 90 volts. If the mains power is above
140 volts and has caused the PS-PRO II to re-
move power from its outlets, the PS-PRO II will
not restore power to its outlets until the mains
voltage is less than 130 volts. The reason for
this is to prevent the power from oscillating on
and off in marginal conditions.
DElaY aDJuST: This screwdriver-adjustable
trimpot allows you to set the total turn-on/turn-off
delay time from 1 to 60 seconds, as explained
on page 6. The trimpot adjusts both the on
delay and off delay times simultaneously. Turn
the trimpot clockwise to increase the on and off
delay times; turn the trimpot counterclockwise
to decrease the delay times.
