Description
The SurgeX SEQ1200i is a 240V rack-mounted power
sequencer incorporating SurgeX power conditioning and surge
elimination. The single rack-space steel enclosure is designed
to be installed in a 19 inch equipment rack. A total of 10 IEC
receptacles are provided on the rear panel. Two are always
on, with the remaining eight configured as four sequenced
banks of two receptacles per bank. 4 models are available
with load capable circuitry and connectivity that conform to
AS3112, BS1363, BS546 and CEE7/7 standards.

Installation
The SurgeX SEQ1200i is designed to be installed in a
standard 19 inch equipment rack and requires one unit (1-U)
of rack space. Use four rack screws to secure the rack ears
to the rack rails. Connect power to the unit by plugging the
cord into a suitable 240V, earthed AC receptacle. The polarity
light on the rear panel will illuminate if live and neutral are
incorrectly connected. If the polarity light is illuminated reverse
the power plug where appropriate or get an electrician to
correct the wiring of the receptacle.
240 Volt Connections
The sequencer has a total of 10 receptacles: four sequenced
banks of two, and two always on. Consult the table below for
the load capabilities of each model. Plug the equipment into
the receptacle banks as needed to turn on equipment in the
required sequence. The Always On receptacles provide power
as long as AC is supplied to the SEQ1200i. The SEQ1200i
runs sequentially during power up and down, Bank A always
powers up first and off last, Bank D always powers up last and
off first.
are all on the front panel. The always-on receptacles will be
powered up whenever the mains voltage is within normal
limits, the sequenced receptacles will only be activated if the

power switch is on and a signal is also being received at the
remote control terminal block on the rear panel. Status LED's
on the front panel show the status of each bank. Red is off
and green is on. Flashing yellow LED's between the bank
LED's indicate the unit is running a power up or power down
sequence.
Multiple units can be cascaded to provide a scalable power
control platform. A single sequencer can also control multiple
SurgeX remote control products (Such as the RT or RTi) to
provide additional banks and also add more load capacity.
This is achieved by wiring units together using the remote
control terminal blocks on the rear panel. Remote control can
be accomplished by using either a contact closure or a DC
voltage from 5V to 30V. Terminals are also provided for an
external status LED.

Remote Control Connections
Remote connections are wired to the green 7-pin plug-in
terminal block on the rear of the unit next to the power cord.
After you have made the connections to the terminal block,
plug it into the connector on the rear of the unit. Never solder
(tin) wires before inserting in a terminal block – the solder will
cold-flow and you will eventually have loose connections!

Sequence Control Input
The sequencer can be controlled by either a contact closure
or a DC voltage from 5V to 30V. A contact closure can be a
relay contact or a latching switch. A latching switch is one that
stays in either the on or the off position (like a light switch).
To use a relay contact or latching switch connect the contacts
to pins 1 & 2. To use a DC voltage connect the negative wire
to pin 3 and the positive wire to pin 2. If the unit is going to
be operated only by the front panel switch without a remote
control input then place a short jumper wire between pins 1 &
2. Switches with gold contacts are recommended for the best
long-term reliability.
External LED Connections
The 12V LED output (pin 4) is able to power an external LED
and will provide 10mA of current. An external LED connected
to this output will indicate when the sequencer is powered up.
It is not necessary to use a series resistor unless the LED is
too bright. If this is the case you can try a 1K resistor or a 2.2K
resistor in series with one of the LED leads. Connect the LED
anode to the 12V LED Output and the cathode to Common.
Confirmation Feedback
The sequencer offers two ways to provide confirmation
feedback to a central controller: isolated relay contacts or
the 12V LED output. Confirmation tells the controller that the
unit has indeed powered up or that it is fully powered down. If
the auxiliary relay contacts and 12V LED output are not used
for any other function, you will be free to choose whichever
provides the best interface for the application. However, if one
of these outputs is used for another function you will have to
use the one that is available.
To use the 12V LED output for confirmation, connect the 12V
LED Output pin to the positive input of the controller and the
Common pin to equipment earth. The output will be at 12V
when the unit is powered up and will be at zero volts when all
banks are powered down. Note that the common terminal is
shared between the inputs and the 12V LED output, and that
the 12V LED output is limited to 10mA.
Operation
The sequencer can be used in one of three configurations:
as a stand-alone four-bank sequencer; with another remotecontrollable SurgeX product as a combination five-bank
sequencer or connected with other sequencers as a cascaded
system of two or more units.
First, make all basic connections as explained above. Then, if
the system includes more than one unit, make the additional
control connections between units as per the application
diagrams. Finally, select the delay time by inserting a small
screwdriver in the hole in the front panel. The available delay
times are: 2s, 5s, 10s, 15s and 20s. The delay time must
be selected on every unit when multiple units are cascaded
together.
When all banks are off the bank status LED's are red. If the
sequencer is to be powered up only by using the front panel
power switch then bridge pins 1 & 2 on the remote control
connector with a jumper. If a remote control input is to be
used to power up the sequencer then leave the power switch
on. The power switch must be on to initiate the power-up
sequence whether a remote control input is used or not. If
the power switch is not being used it can be turned on and
then covered using the supplied switch cover. When multiple
units are cascaded all the slave units should have their power
switches turned on and covered.
When the power switch is on and the remote control input
is activated the unit will begin the power up sequence. The
remote control input is activated by either a contact closing
(pins 1 & 2) or a voltage of 5-30V being applied (pins 2 &
3). Bank A will always turn on first, then banks B, C & D. As
each bank switches on, the front panel bank status LED's
change from red to green. The flashing yellow LED's indicate
the power up sequence is running. Finally, after bank D is
powered up the auxiliary relay activates after the set delay
time. The auxiliary relay contacts are connected to the remote
control connector pins 6 & 7 and can be used to control
another unit or provide feedback to a central controller.
When either the power switch is turned off or the remote
control input is deactivated the unit will begin the power down
sequence, this is the reverse of the power up sequence. The
auxiliary relay will turn off first, then banks D, C, B & A. As
each bank switches off, the bank status LED's change from
green to red. The flashing yellow LED's indicate the SEQ1200i
is waiting for the delay time to elapse before moving to the
next bank. When multiple units are cascaded together the last
unit in the chain powers down first.
Other Status LED's
Red Power LED: Shows that the mains is connected and the
power switch is on.
Green Self Test LED: Illuminates to indicate that the surge
elimination circuitry is fully operational.
Orange Over/Under-Voltage Shutdown LED: Illuminates if the
mains voltage rises above 280 volts or falls below 180 volts.
When this LED is illuminated all receptacles are turned off.
