1Description

The SurgeX®XQ515 is a 120V 20 amp three-bank AC power sequencer incorporating SurgeX®

Advanced Series Mode®power conditioning and surge protection. The surge protection is rated

A-1-1, the highest standard of the Federal Commercial Item Description for Endurance. The two

rack-space steel enclosure is designed to be installed in a 19 inch equipment rack. A total of

fourteen 120V receptacles are provided on the rear panel, two of which are always on, with the

remaining twelve configured as three sequenced banks of four receptacles, labeled A, B and C.

Bank C (which is next to the two always-on receptacles on the rear panel) can itself be

configured to be always on, increasing the number of always-on receptacles to six.

SurgeX ICE®Inrush Current Elimination circuitry is incorporated into the XQ515. This

eliminates problems associated with inrush currents from large loads such as amplifiers. With

SurgeX ICE®it is not necessary to take inrush currents into account when designing the AC

power for a system, and special time-delay circuit breakers are not required: you only need to

ensure that the steady-state currents of all products plugged into the XQ515 are within the 15

Amp rating.

The front panel houses a two-line back-lit LCD display which provides status information in

normal use and allows interaction with menu items during programming. Also on the front panel

are two screwdriver-accessible rotary encoders which are used to step through and select from a

menu of items which determine the operation of the unit. The red push button, when pressed,

causes the unit to power up or power down. This button can be disabled if not required. The red

LED above the button indicates the status of the unit. When the red LED is off the unit is fully

powered down; when it is on the unit is fully powered up; when it is flashing the unit is in the

process of powering up or down.

A built-in AC voltmeter indicates the line voltage on the LCD display. The internal voltmeter is

a peak reading type which was chosen because most electronic equipment incorporates a power

supply that charges mostly during the AC peaks. Monitoring the peak of the AC provides a more

useful indication of the real voltage available to the electronic equipment plugged into the

XQ515.

The XQ515 is microprocessor controlled and designed to be versatile and expandable. Two or

more XQ515s can be connected together to provide control and power conditioning for larger

systems. The XQ515 can also control other SurgeX products like the XR315 with its auxiliary

relay contacts and/or its 12V DC output. All options are set via the front panel and all

connections are made at the rear panel. An optional password of up to six letters can be entered

preventing unauthorized access to set-up information. All set-up information is stored in non-

volatile memory.

A plug-in Phoenix terminal block on the rear panel accommodates the remote control

connections and also the low-voltage outputs. There are three inputs which control sequencing;

one programmable 12V dc output; and one programmable auxiliary relay providing normally-

open contacts. The inputs can be controlled by an applied DC voltage from 5V to 30V, by a

contact closure, or by different types of switch; the input selection being made during

programming. The inputs and 12V output are designed to withstand incorrect connections

including polarity reversal and shorts.

3Installation

The SurgeX XQ515 is designed to be installed in a 19 inch equipment rack and requires two

units (2-U) of rack space. Use the four screws provided with the product to secure the rack ears

to the rack rails. These screws can be tightened by hand and do not require tools. Connect power

to the unit by plugging the cord into a 120V ac, 15 Amp receptacle.

3.1 120 Volt Connections

The XQ515 has a total of 14 receptacles: three sequenced banks of four, and two always on.

Each receptacle is rated for a maximum load of 15 amps but the total load of the XQ515 must

not exceed 15 Amps. Plug the equipment cords into the receptacle banks as needed to turn on

equipment in the required sequence. The “always on” receptacles provide power as long as

power is supplied to the XQ515. Bank “A” always powers up first and off last.

3.2 Remote Control Connections

Remote connections are wired to the green 7-pin plug-in Phoenix terminal block on the rear of

the unit next to the power cord. The terminal block itself is provided in the accessory bag that

you will find in the shipping box. 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 –solder creeps and you will eventually have loose connections!

The connections are shown below:

3.2.1 Up/Down XQ515uence Control Inputs

The XQ515 can be controlled by a DC voltage in the range 5V to 30V, by a contact closure (such

as a relay), or by a switch. In this manual the terms “momentary” and “latching” are used when

describing switches. A momentary switch is considered to be a switch which provides a

connection only while it is actually held pressed, and a latching switch is considered to be a

switch which remains in either the on or the off state (like a light switch). Momentary switches

are preferred for use with the XQ515 since multiple control locations can be used, and also

because some of the functions of the XQ515 are not available when a latching switch is used (see

programming section). Switches with gold contacts are recommended for the best long-term

reliability. The type of input is selected totally through programming, making the electrical

connections straightforward. The six control options are discussed below:

a) DC Voltage: The XQ515 will power up when the voltage is present and power down

when there is no voltage. Connect the positive wire to the “up” input, and the ground (or

negative) wire to “common”. Program the input for “5-30 V dc”.

b) Contact Closure: The XQ515 will power up when the contacts are closed and power

down when the contacts are open. Connect the two wires from the contacts to “up” and

“common”. Program the input for “Latching”

c) Momentary Switch(es): The XQ515 will power up when a switch is pressed once and

power down when a switch is pressed a second time. Connect the two wires from the

switch(es) to “up” and “common”. Program the input for “Momentary”.

d) Separate Up & Down Switches: The XQ515 will power up when the UP switch is

pressed and power down when the DOWN switch is pressed. Connect the two wires from

Pin 1 –Up Input

Pin 2 –Down Input

Pin 3 –Over-Ride Input

Pin 4 –12 V dc Output

Pin 5 –Common

Pin 6 –Aux Relay Contact

Pin 7 –Aux Relay Contact

the UP switch to “up” and “common”, and the two wires from the DOWN switch to

“down” and “common”. Program the input for “Separate Up & Down”.

e) Center-Off Switch: The XQ515 will power up when the switch is pressed to the UP

position and power down when the switch is pressed to the DOWN position. Connect the

wire from the UP terminal to “up”, the wire from the DOWN terminal to “down”, and the

wire from the COMMON terminal to “common”. Program the input for “Separate Up &

Down”.

f) Latching Switch: The XQ515 will power up when the switch is closed and power down

when the switch is open. Connect the two wires from the switch to “up” and “common”.

Program the input for “Latching”.

Note: The front panel button will not operate with options a, b or f

3.2.2 Over-Ride Input

The XQ515 has the option of adding an over-ride function for purposes such as providing fire

safety over-ride to force the system either on or off. An over-ride is initiated by applying a dc

voltage of 5-30V or by a sustained contact closure. The selection of dc voltage or contact closure

is accomplished during programming. This topic is covered fully in the programming section.

Connect the over-ride signal to the “over-ride” input and “common”. In the case of a dc voltage,

connect the positive wire to “over-ride” and the negative wire to “common”.

3.2.3 External LED Connections

The XQ515 is able to drive external LEDs or other signaling devices through its 12V dc output

which can provide up to 40mA of current. External LEDs connected in this way will mimic the

red LED on the front panel. When connecting LEDs to the 12V output, a series resistor is

required. For example, many LEDs work well with 10mA of current, so a 1K resistor is usually a

good choice. If more than one LED is required, then use a separate series resistor for each LED.

In this example, four external LEDs could be powered at 10mA each from one XQ515. If more

than four LEDs are required, it will be necessary to increase the series resistor so that the total

load is not more than 40mA.

Connect each LED anode to “12V dc output” through a resistor, and the cathodes to “common”.

Program the 12V dc Output for “LED”. This causes LEDs connected to the XQ515 to flash

while the unit is powering up or powering down in the same manner as the front panel LED.

3.2.4 Confirmation Connection

The XQ515 offers two ways to provide confirmation feedback to a central controller: a 12V dc

output and isolated relay contacts. Confirmation tells the controller that the XQ515 has indeed

powered up or that it is fully powered down. If the 12V dc output and the aux relay contacts 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 dc output for confirmation, connect “12V dc output” to the positive input of the

controller and “common” to ground. The output will be at 12V when all banks are powered up

and will be zero when all banks are powered down. Program 12V dc Output for “Confirm”. Note

that the XQ515 common terminal is shared between the inputs and the 12V dc output. If you

need relay contacts for confirmation and you are using the aux relay for another function you can

connect a small relay between the 12V dc output and common. The relay coil current must not be

more than 40mA, and you must connect a diode such as a 1N4148 or 1N4002 across the relay

coil (cathode to +12V dc) to suppress the back-EMF from the coil. If you need assistance with

this please contact our technical support department.

Connecting a 12 volt relay to the 12V dc output

To use the auxiliary relay contacts for confirmation, connect the contacts to the input of the

controller. The relay contacts will be closed when all banks are powered up and open when all

banks are powered down. The default for menu item “Aux Output” is “Confirm” so you do not

need to program this item unless you previously changed it. The contacts are rated for 30V dc at

1 amp.

4Quick Start

This section is intended to allow users with a simple straightforward system incorporating a

single XQ515 to get up and running with the minimum of effort. If this is not the case then skip

this section and go directly to the section on detailed programming (section 5). If you are going

to follow the quick start instructions, you only need to perform the following steps since the unit

has been shipped with default settings suitable for basic operation.

1. Make all connections as per section 3.

12V dc Output

Common

2. Insert the screwdriver provided in the accessory kit in the hole labeled SEL and turn it one

click clockwise. Press the red button and you will see the first menu item “Bank C Function”

on the display. Leave this set to sequence unless you want to use Bank C as Always On

receptacles. In that case insert the screwdriver in the hole labeled ADJ and turn one click

clockwise to change it to Always On.

3. Advance SEL one click to get the second menu item “Up & Down Inputs”. Select the option

required for the install by referring to section 3.2.1 and set the option by rotating ADJ.

4. Advance SEL one more click. You will now be able to set the first delay time which is for

bank A powering up. Use ADJ to set the required delay time in seconds.

5. Advancing SEL one click at a time and using ADJ to adjust the delay times, set the

remaining five delay times: B on, C on, A off, B off, C off. If you have set Bank C to be

Always On skip the delay settings for Bank C.

6. If you have connected an LED to the 12V dc output for remote signaling, step through the

menu until you reach “12V dc Output”. Then advance ADJ to select “LED”. This selection

will make the remote LED mimic the LED on the front panel which flashes while the unit is

powering up or powering down.

7. Turn SEL fully counter-clockwise and press the red button to exit programming. Place two of

the black plugs from the accessory kit into the adjustment holes to deter tampering and the

unit is ready for use.

Although the above steps are all that are required to get the XQ515 running, you may want to

take a look at the following programming options to see if you want to make use of any of these

functions. You will find these listed on the reverse side of the Programming and Connection

Guide, and they are near the end of the menu that you step through by turning SEL.

Low Voltage Shutdown Shuts unit off if AC voltage drops below the set point

High Voltage Shutdown Shuts unit off if AC voltage rises above the set point

Self-Test Shutdown Shuts down unit if self-test fails

Power Fail Restore Turns unit back on after a power failure if unit

was powered up when the power failed

5Programming

The XQ515 is a very versatile sequencer and has 25 menu items that control its operation. Some

menu items allow predetermined options to be selected and others allow time delays or voltage

limits to be adjusted. All adjustments are made via the front panel and are achieved by turning

the two screwdriver-accessible rotary encoders labeled SEL (select) and ADJ (adjust). Turning

SEL steps through the menu (shown on the first line of the display), and turning ADJ allows each

menu item to be changed (shown on the second line of the display). The accessory kit contains a

screwdriver suitable for making adjustments and black plugs to cover the holes when

programming is complete.

To enter the programming mode first turn SEL one click clockwise. The display will then tell

you to press the red button. This puts you into the programming mode. All the options, delay

times and voltage adjustments are set using this mode. When you have completed the set-up turn

SEL counter-clockwise until the display tells you to press the red button again. Doing so saves

the new set-up information in non-volatile memory and puts you back into normal operation.

A password can be set while in the programming mode. Once a password has been set, you need

to enter the same password before you can get back into the programming mode again. This

prevents unauthorized personnel from changing the set-up information. The password option is

the last menu item and can be from one to six letters (A-Z).

You must be sure to remember the password once it is set as the only way to erase it is to erase

all the set-up information stored in the non-volatile memory. Please consult the factory to get

instructions if you ever need to do this.

The instructions and notes that follow are in the same order as the actual menu items.

5.1 Power XQ515uencing Control

The following eight menu items must be set before the XQ515 can be used in a system. These

determine the function and delay times of the XQ515uenced banks, and the type of control input:

DC voltage, contact closure or switch. Please see section 3.2.1 for details.

Bank C Function Select normal XQ515uencing or Always On

Up & Down Inputs Select the option as per section 3.2.1

Delay A On Set the delay in seconds for Bank A powering on

Delay B On Set the delay in seconds for Bank B powering on

Delay C On Set the delay in seconds for Bank C powering on

Delay A Off Set the delay in seconds for Bank A powering off

Delay B Off Set the delay in seconds for Bank B powering off

Delay C Off Set the delay in seconds for Bank C powering off
