1 Description

The SurgeX® XR315 is a 120V, 15 Amp AC power quality product 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 one rack-space steel enclosure is designed to be installed in a 19 inch equipment rack, or placed on a flat surface. A total of eight 120V receptacles are provided on the rear panel.

Surge X ICE® Inrush Current Elimination circuitry is incorporated into the XR315. This eliminates problems associated with inrush currents from large loads such as amplifiers. With Surge X 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 XR315 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. The character display intensity is adjusted by either a rotary dimmer knob or a push-button On/Off switch. 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 power button, when pressed, causes the unit to power up or power down. This button can be disabled if not required. The LED incorporated into the button indicates the status of the unit. When the 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 XR315.

A built-in AC ammeter indicates the total current consumption of connected equipment on the LCD display. The internal ammeter is also a peak reading type.

A calculation of the total power being delivered to connected equipment is displayed on the second line of the LCD display. Power is calculated as the product of the line voltage and total current draw, and is displayed with the unit Watts “W”. Volt-Amps (“VA”) is the more correct unit of power, since the voltage and current measurements are based on a peak reading, but Watts is displayed for simplicity.

The XR315 is microprocessor controlled and designed to be versatile and expandable. Two or more XR315s can be connected together to provide control and power conditioning for larger systems. The XR315 can also control other SurgeX products 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. 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 power state; one programmable 12V dc output; and one programmable auxiliary relay providing normallyopen 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.

3 Installation

The SurgeX XR315 is designed to rest on a flat surface or to be installed in a 19 inch equipment rack and requires one unit (1-U) of rack space. To place the XR315 on a flat surface, use four 6-32 Phillips pan head screws (included) to attach the four decorative feet (included). To install in an equipment rack, use eleven 6-32 Phillips flat head screws (included) to attach the removable rack-mounting brackets (included) to the sides of the product. Use the four thumbscrews 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 wall or floor receptacle. Do not plug the unit into a relocatable power

tap. *CAUTION: Do not install this device if there is not at least 10 meters (30 feet) or

more between the electrical outlet and the electrical service panel.

3.1 120 Volt Connections

The XR315 has a total of 8 receptacles. Each receptacle is rated for a maximum load of 15 amps but the total load of the XR315 must not exceed 15 amps.

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 Control Inputs

The XR315 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 XR315 since multiple control locations can be used, and also because some of the functions of the XR315 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 XR315 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”.

Pin 6 – Aux Relay Contact

b) Contact Closure: The XR315 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 XR315 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 XR315 will power up when the UP switch is pressed

and power down when the DOWN switch is pressed. Connect the two wires from 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 XR315 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 XR315 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 XR315 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 XR315 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 XR315. 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 XR315 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 XR315 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 XR315 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 the XR315 is powered up and will be zero when the XR315 is powered down. Program 12V dc Output for “Confirm”. Note that the XR315 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 the XR315 is powered up and open when the XR315 is 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.

4 Quick Start

This section is intended to allow users with a simple straightforward system incorporating a single XR315 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.

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

click clockwise. Press the power button and you will see the first menu item “Unused” on the display. This is a function that is not available in the current software/hardware configuration.

3. Advance Select 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 Adjust.

4. 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 Adjust 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.

5. Turn Select fully counter-clockwise and press the p ower 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 XR315 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 Select.
