PS-PRO - POWER CONDITIONER/SEQUENCER
fault. Since any wiring fault presents a potentially
serious safety hazard, the assistance of a qualified
electrician should be obtained in correcting the
problem.
NOTE: The Mains Wiring indicators and status LEDs
stay on even when the power switch is off. This
feature allows you to check the mains wiring before
powering up your equipment. These indicators are
designed for continuous, ongoing use. Like a clock,
they consume very little power.
UNSWITCHED OUTLET: This convenient outlet pro-
vides power at all times when the PS-PRO is plugged
in and operating under normal power conditions.
ON/REM/OFF SWITCH: When turned to the ON posi
-
tion, this key lock switch initiates an ON sequence,
applying power to the PS-PRO’s switched outlets.
When turned to the OFF position, it begins an OFF
sequence. In the REM position, the PS-PRO will
accept on/off commands from a remote switch or
switches that may be connected to the rear panel
terminals.
CIRCUIT BREAKER: The overall capacity of the
PS-PRO is 20 amps. If the combined steady-state
current drawn by all devices plugged into all of its
nine outlets level exceeds 20 amps at any time, the
circuit breaker will trip, cutting off power to your
rack. If this occurs, you must reduce the load by
unplugging one or more units from the PS-PRO,
and reset it. You can reset the circuit breaker by
simply pressing in the button, which pops out when
tripped. However, because 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.
UNSWITCHED OUTLETS: The PS-PRO rear panel pro
-
vides clean, filtered power to this pair of unswitched
outlets, adjacent to the power cord.
SWITCHED (DELAYED) OUTLETS: The PS-PRO rear
panel provides three pairs of switched outlets,
widely spaced to allow use of equipment with
plug- in (wall wart) transformers. 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 instantly, Delay 2
outlets receive power 1-30 seconds later and Delay
3 outlets receive power 130 seconds after Delay
2 outlets are powered. When thrown to OFF, the
sequence is reversed, with
Delay 3 losing power instantly, Delay 2 outlets los-
ing power 1-30 seconds later and Delay 1 outlets
losing power 1-30 seconds after Delay 2 outlets are
shut down. The delay intervals may be altered with
the screwdriver-adjustable Delay Adjust control
on the front panel.
TERMINAL STRIP: Allows one or more switches to be
connected to turn the PS-PRO on and off from a re
-
mote location. Two, and sometimes three, wires are
needed to install a remote switch (see “Maintained
Mode”, page 6.) If a four-conductor cable is used, an
LED may be installed at the remote end to indicate
that the power is on.
