Plus-X 300 Installation and Operation Manual Rev C
1
Introduction
The Plus-X 300 works in conjunction with the Burk Technology ARC Plus transmitter remote
control to provide eight inputs and eight outputs for remote monitoring and control. Metering and
status inputs are sent from the Plus-X 300 to the ARC Plus via Ethernet. The ARC Plus then
reports these values as independent metering and status channels. The relay outputs on the
Plus-X 300 are controlled by the ARC Plus via commands and macros.
The Plus-X 300 has eight (8) inputs, each configurable as metering or status. Eight (8) output
relays allow control of site equipment. Relays may be activated independently or operated in
pairs for mutually-exclusive output.
Compatibility
Before installing the Plus‐X 300, please verify that the ARC Plus firmware, AutoPilot software
and AutoLoad Plus software versions are current. Updates are available at
www.burk.com/downloads.
The following are minimum software and firmware requirements:
Software
Version

AutoPilot® software
2.6 or higher
Installation
The Plus-X 300 ships with the following parts, which are required for installation:
(1) Ethernet cable
(1) 15V wall adapter
(1) 2-pin Phoenix-type connector (for power connection)
(1) 9-pin Phoenix-type connector (for input channels)
(2) 12-pin Phoenix-type connectors (for relay outputs)
(4) Rubber feet (for optional horizontal mounting)
For wall mounting, secure the Plus-X 300 using #8 hardware (not included) and chassis cutouts.
Alternatively, the Plus-X 300 may be mounted flat on top of an equipment rack, shelf or another
suitable location.
Input Wiring
Metering and status channels are wired to the Plus-X 300 using the included 9-pin connector
block. To connect metering and status inputs, loosen the screws on the connector block and
connect voltage wiring from the site equipment to the Phoenix connector inputs to align with the

Plus-X 300 Installation and Operation Manual Rev C

1-8 numbering on the chassis. Insert a common ground reference to the Phoenix connector to
align with the ground symbol on the chassis. Tighten the set screws.
Relay Output Wiring
Command output wiring is facilitated by the two 12-pin connector blocks. Each relay 1-8 has
Common (C), Normally Open (NO) and Normally Closed (NC) connections labeled on the rear
panel. Loosen the set screws on the Phoenix connectors and make wiring connections
according to the requirements of the site equipment under control. Tighten the set screws.
When finished making equipment connections, disconnect the Phoenix connectors from the
Plus-X 300 until configuration is complete.
Power & Ethernet Connections
Apply power to the Plus-X 300 by connecting the 2-pin power connector to the rear-panel input
marked POWER. The power connector is pre-wired to the 15V wall adapter. Plug the power
adapter into a standard 120V outlet. The POWER LED will illuminate.
Finally, connect the included Ethernet cable to your network switch.
Important!
The Plus-X 300 must be addressable by the ARC Plus to which it will communicate. Consult your IT
department prior to configuration to resolve any IP address or firewall conflicts.
Configuration
Configuring the Plus-X 300 involves establishing the network settings, setting up channel
parameters, setting the password, and then adding the newly configured Plus-X channels to the
ARC Plus system.
To configure the Plus-X 300, open a web browser and enter the unit’s IP address in the address
bar. Prior to network configuration, the Plus-X 300 operates on a default IP address of
192.168.0.100. When the login screen appears, enter the user name and password for the unit.
The user name is admin and the default password is password.

Network Settings
After logging in, the first page you will see is the Network
Settings page. Enter the network settings where
prompted. Note that the default Plus-X port of 45000 will
work in most installations. However, if you have
changed the Plus-X port during ARC Plus configuration
the Plus-X port you enter here should match that setting.
The ARC Plus IP address field calls for the IP address of
the ARC Plus that will host the metering, status and
command channels of the Plus-X 300.
Press the Update Settings button when you are
finished.
Channel Settings
The Channels page is where you configure high and low
status thresholds for up to eight status channels, as well
as relay behavior for each of eight relay outputs.
In the Status Thresholds table, enter the input values
that will trigger status changes from low to high and vice
versa. The Lower threshold is the value below which a
voltage sample must decrease in order to change the
status from high to low. The Upper threshold is the
value above which a voltage sample must increase in
order to change the status from low to high.
Voltages between the lower and upper thresholds do not
cause a status change on the ARC Plus. For example, if
a voltage sample increases beyond the Lower threshold,
but does not reach the Upper threshold, the status indicated on the ARC Plus does not change.
Note that each input may be used as a metering channel, status channel or both. In other
words, an analog temperature reading may also drive “high temp” and “low temp” status alarms.

Next, define the behavior for each of eight relay outputs.
Each relay may be set for momentary or latching output.
Check the Pair Relay Channels box in order for the relays
to act as mutually exclusive pairs. When this box is
checked, a command to one relay will cause the second
relay to de-energize.
Note: When the Pair Relay Channels box is checked, it is
recommended to configure the two paired relays with the same behavior (Latching / Latching or
Momentary / Momentary). If one relay is configured as Latching and the other as Momentary, a
command to the momentary relay will de-energize the latching relay. After the momentary
command is finished, both relays will remain de-energized until a new command is issued to
one of the relays.
Security
Navigate to the Security page to set the
password for the Plus-X 300. This password is
used only to access the Plus-X configuration
screens. ARC Plus user names and passwords
are set up using AutoLoad Plus software.
The Plus-X 300 user name is always admin.
Adding Plus-X Channels to the ARC Plus
Now that you have configured the input and output channels on the Plus-X 300, these channels
may be added to the ARC Plus site using AutoLoad Plus. To add Plus-X 300 channels to the
ARC Plus:
1. Launch AutoLoad Plus and connect to the ARC Plus site to which the Plus-X 300 is
linked.
2. From the Edit menu, select Plus-X Devices…and click New.
3. When the Plus-X Settings window appears, select Plus-X 300 from the device type drop-
down. Enter a description of the Plus-X 300 for your own reference, followed by the IP
address and Plus-X port, both of which are already configured on the Plus-X 300.
4. Check the box marked Map Default Set of Channels to add all eight inputs and eight
relays to the ARC Plus. If you are not using all Plus-X 300 channels or if you do not wish
for them to appear in sequential order, you will need to manually map these channels
later. In this case, leave the Map Default Set of Channels box unchecked.
5. Press OK to close the Plus-X Settings window. Press OK to close the Plus-X Devices
window.
6. To manually map Plus-X 300 channels to the ARC Plus, click the Metering, Status or
Commands tabs, as appropriate. Locate an unused channel and click the […] button in
the Source column. This will bring up the Source dialog box. Click the Plus-X button and
choose the Plus-X 300 channel you wish to use. At least one meter channel and one

command channel on the Plus-X 300 must be configured within the ARC Plus for the
Plus-X device to register as online in the ARC Plus system.
7. Configure labels, limits and alarms for the newly added Plus-X 300 channels in the same
way as you would configure labels, limits and alarms for normal ARC Plus channels.
8. Lastly, you will need to calibrate the Plus-X 300 channels. If you have not already
connected the input connector blocks, do so now. Then click the Calibration icon in the
AutoLoad Plus toolbar to complete the calibration process.
Restoring Factory Configuration
To reset the unit to its default configuration, press the front panel Config button three times.
The Power LED will blink to confirm the configuration has been reset. Note that the restoring
default configuration will reset the unit’s password to password and revert the IP address to
192.168.0.100.
Uploading New Firmware
After logging into the Plus-X 300 web interface, edit the URL in your web browser to
[address]/upload, where [address] is the IP address assigned to the Plus-X 300. This will take
you to the upload page.
Click the Choose File button to select the firmware file, then click Upload to load the new
firmware. The Plus-X 300 will reboot after the firmware upload is complete.
Operation
Taking Readings & Issuing Commands
Once you have added Plus-X 300 channels to the ARC Plus, they appear on the ARC Plus front
panel, AutoPilot software, Web Interface and RSI speech interface just as any other ARC Plus
channel. They can be used in macros and custom views. The Plus-X 300 is responsible for
reporting the raw sample values to the ARC Plus, while the ARC Plus applies the calibration
constant, limits and alarm settings.
Maintenance Mode
Maintenance Mode is a safety feature that prevents command execution while personnel are
performing work at the remote site. Maintenance Mode on the Plus-X 300 can be activated by

Plus-X 300 Installation and Operation Manual Rev C

two means: 1) placing the ARC Plus in maintenance mode using the ARC Plus front panel
menus; and 2) placing the Plus-X 300 in maintenance mode using the Plus-X front panel MAINT
button.
When the ARC Plus is in maintenance mode, it will not issue commands or macros to any ARC
Plus channels, including Plus-X 300 channels. It is still possible to issue test commands via the
Plus-X 300 diagnostics page (see page 6).
When the Plus-X 300 is in maintenance mode, the ARC Plus can issue commands and macros
to other channels, but Plus-X 300 commands are disabled.
Maintenance mode must be toggled from the respective front panels. For safety reasons, it
cannot be enabled or disabled by any remote means.
Diagnostics
The Plus-X 300 has a diagnostics page built in to the configuration web pages. This allows
administrators to verify raw input voltage readings against real-world measurements and to test
relay behavior; it is not intended for routine monitoring and control of equipment.
To access the diagnostics page, open a web browser and enter the IP address of the Plus-X
300. After logging in, use the links at the top of the screen to navigate to the Diagnostics page.
