DESCRIPTION
The RLP-2024BBSCLVD-MU is a Heavy Duty AC to DC Power Supply with smart charger that is web ready for remote
monitoring and control. The new internal Remote Monitoring and Control Unit (RMCU), provides the ability to remotely monitor the AC
voltage, battery voltage, power supply voltage for each module, power supply current for each module, battery current, LVD status,
external alarm status, as well as the ability to remotely control the state of each power supply module, all via the internet using any
standard web browser. A mobile friendly version of the status page is included, and an alarm output is also provided.
Users that have access to the network can view the status of the power supply, control outputs, and the alarm conditions, as
well as download a .CSV file of logged states. Administrative users can access the setup screens and change the control settings by
logging into the RLP-2024BBSCLVD-MU via the browser. Alarm conditions are configurable, and can include over and under
thresholds and discreet logical inputs. Notifications via email can also be configured to notify an administrator. Setups are saved in non-
volatile RAM, and a battery backed up real-time clock is provided to timestamp information logged to the internal SD card. Logging rate
is user settable.
This power supply comes with power factor correction, and with front panel metering for voltage and current. All of the RLP
series come with four layers of protection against overload, over voltage, over temperature, and short circuit protection. This model also
comes with a manual battery disconnect.
The RLP-2024BBSCLVD-MU comes with the DuraComm three-year warranty.

METER CIRCUITS
The panel meter is switched to provide DC output voltage measurement and individual output load current measurement for each
individual module.
When set to the VOLT position, the full scale reading is 30 volts.
When set to the AMP position, the full scale reading is 30 amps.
The meter and associated circuitry accuracy is 10 percent of full scale deflection. Since full scale is 30 amps, a 20 amp current can
vary from 18 to 22 amps indicated. To prevent unnecessary output voltage drops, the meter circuits use the voltage drop of the black
#12 AWG negative return to the module as a meter shunt. The #12 AWG wire provides a nominal 50 mV drop at 30 amps
The meter sensitivity for voltage measurement is 1000 ohms per volt.

INSTALLATION BLOCK DIAGRAM
Output Power Wiring Layout
This system setup will provide continuous power to the load and maintain battery bank with smart charger while AC power is
on. There is a seamless transfer of the load to the battery when the AC power goes off. The LVD will disconnect the battery if the
voltage drops below 20 VDC. The battery reconnects once AC power is restored and voltage reaches 25 VDC.

Remote Monitoring and Alarm Wiring
The Alarm input connections require normally closed contacts between Alarm IN and +5V for a typical setup. When the
circuit opens, the Alarm Input will turn RED on the status page.
The Alarm output provides an open collector (Open MOSFET drain) form control of external equipment. A load may be
connected to the +5V terminal and the Alarm OUT. Alternately, you may use up to a +60VDC external supply. The Alarm
OUT pin will sink up to 500 mAmps Max when turned on.
NOTE: The ‘G’connection on the alarm terminal strip is the same as Power Supply and Battery Negative, so the RLP-
2024BBSCLVD-MU is not designed for Positive Ground applications.
The RJ-45 connects the RLP-2024BBSCLVD-MU to your 10/100 Ethernet network.

CONNECTING TO THE RLP-2024BBSCLVD-MU VIA THE INTERNET
Prerequisites
System administrators must decide whether the RLP-2024BBSCLVD-MU will operate on the network with DHCP or a
fixed IP address. The factory-set RLP-2024BBSCLVD-MU will have these static addresses: IP address: 192.168.100.220,
gateway address: 192.168.100.1, netmask: 255.255.255.0, and DNS address: 192.168.100.1.
If you configure it to use DHCP, the RLP-2024BBSCLVD-MU will request an available IP address on your network. You will
need to determine what address it has been given.
If DHCP is not used, system administrators must also choose an unused IP address, and other network settings to use in
the Network Setup screen. System administrators will also need to choose an email service and address to use for
notifications, if needed. These will be used in the Email Setup Screen.
DETERMINING THE IP ADDRESS OF THE RLP-2024BBSCLVD-MU
Power up the RLP-2024BBSCLVD-MU then connect the RLP-2024BBSCLVD-MU to the network with an Ethernet cable.
Using DHCP
You will need to get the IP address in one of two ways. You can get the IP address from the DHCP server’s client list, or
you can use a PC on the same network to scan for the new IP address by using a software tool such as Angry IP Scanner.
In Angry IP Scanner, you should add the MAC address “Fetcher” under “Tools > Fetchers”. The DuraComm MAC
addresses all start with a base address of 70-B3-D5-6B-3. Write down the IP address of the RLP-2024BBSCLVD-MU,
then proceed to the section in this manual named “Open a Web Connection to the RLP-2024BBSCLVD-MU”.
Using Static RLP-2024BBSCLVD-MU IP and Network Configuration
If your network is not set up for DHCP, you will need to manually configure the settings to match the network it will be
used on. Before you can do that, you will need to configure a computer to talk to the RLP-2024BBSCLVD-MU at the
default configuration settings shown above. We will use Windows 7 as an example. Other operating systems will vary,
but the overall concept is the same.
1. Disconnect your PC from all networks.
2. Connect it directly to the RLP-2024BBSCLVD-MU with an Ethernet cable (You may need to use an Ethernet crossover cable if
the PC does not automatically detect this configuration).
3. Open the control panel on your PC and select “View Network Status and Tasks”
4. Click on “Change Adapter Settings” on the left side of the screen.
5. Right click on “Local Area Connection” and click on “Properties”
6. Click on “Internet Protocol Version 4 (TCP/IPv4)” to highlight it, then click the “Properties” button.
7. Before you make any changes, record the existing settings, so that you can change them back when you are finished setting
up the RLP-2024BBSCLVD-MU.
8. Enable “Use The Following IP Address”
9. Now enter 192.168.100.221 for the IP address.
10. Enter 255.255.255.0 Subnet mask
11. Click OK to save the network configuration.
12. Jump to the section in this owners guide named “Open a Web Connection to the RLP-2024BBSCLVD-MU” to log in and
enter the final network settings for the RLP-2024BBSCLVD-MU.

6 of 21 January 25, 2017
Open a Web Connection to the RLP-2024BBSCLVD-MU
1. Connect the RJ-45 connector on the back of the RLP-2024BBSCLVD-MU to your network
2. Use your favorite device and browser (Chrome, Firefox, internet Explorer, etc.), and enter the IP address of the
power supply on your network into the URL box on the browser (see the screenshot below). If you are unable to
connect to the device with the browser, you will need to use a terminal with a USB connection to access the
device and configure the IP address. If the RLP-2024BBSCLVD-MU responds with the “Status” screen, then skip
to the User Login Section.

7 of 21 January 25, 2017
REMOTE MONITORING AND CONTROL (RMCU) SETUP
All setup requires an administrative user to log into the RMCU in your power supply. Click the ‘Login’ button in the top menu.
User Login
Enter the user name and password. Factory default username and password are as follows:
Admin Users have full control of the device.
Username: admin (cannot be changed)
Password: admin
Control users have limited control capability.
Username: control (cannot be changed)
Password: control
These two users are the only ones available in the RMCU. “Control” users can access all screens except the User Setup screen.

Network Setup
A network administrator for your company must choose the settings for this page. The default HTTP port is 80. If a
different HTTP port is used, it will need to be added to the URL to access the V. For example: if the port is changed to
8080 then the address would be changed to http://192.168.0.253:8080
Revision 2.6 FW fixed a bug with saving the Static Netmask Address.
NOTE: You must reboot the device for changes in these settings to take effect.
SNMP TRAPS SETUP
This section is simplified, and meant for network administrators who already understand SNMP traps and how to
configure capable equipment into their system. For those who want to understand the benefits of using SNMP traps,
you can search for training material online under “SNMP Traps”, “MIB Browsers”, and “SNMP Monitoring”.
The MIB file for the RLP-2024BBSCLVD-MU can be downloaded from the RLP-2024BBSCLVD-MU after you connect to it
with your browser. Go to the Device Setup page and log in to the RLP-2024BBSCLVD-MU. Halfway down the page there
is a link to the MIB file. Right click on the link and click “Save Link As” to download the file.
After download, import the MIB file into your MIB browser or Monitoring software to configure it for use with the RLP-
2024BBSCLVD-MU.
When the MIB file has been loaded, complete the “SNMP Setup” section on the “Network Setup” page of the RLP-
2024BBSCLVD-MU to configure it for use with your monitoring solution.
The RLP-2024BBSCLVD-MU will send traps for all configured alarm conditions including bootup, temperature, analog
alarms, and digital alarms.
Digital Outputs can also be controlled by SNMP, and configured for alarms on the RLP-2024BBSCLVD-MU.

Device Info
A custom site name can be entered here, and the model number, serial number, software version, and hardware version
are shown here.
Logging
The RLP-2024BBSCLVD-MU will log all measurements and alarms to an SD card that is plugged into the RMCU board.
Users can set the rate here, as well as clear the card, or append new measurements. The CSV log file can be downloaded
here, as well as the Status page. If the SD card fills up, the oldest sample is discarded when a new one is stored. The RLP-
2024BBSCLVD-MU custom device name is stored with the logged data, so that the source of the card can be identified
after it removed from the RLP-2024BBSCLVD-MU.
For firmware 2.2, the log file will be automatically renamed and a new one started when the file size reaches 5MB.
Download all log files before deleting them!
With REV 2.3 Firmware, the ability to log readings when an alarm occurs has been added. To turn off periodic logging,
just enter 0 as the logging rate. You can set up logging to occur only on alarms, periodically, both or none.
SNMP MIB File Download
The SNMP MIB File can be downloaded from this page.
Date and Time Settings
Configuration for all date and time settings. Date and time is battery backed up on the card, and the values are saved in
the logged samples. The real-time-clock can synchronize it’s time to the network through an NTP server, or it can be set
manually if a network is not available.
The NIST NTP servers can be used by entering time.nist.gov or pool.ntp.org, or another NTP server address into
the NTP Server box.
Miscellaneous Settings
With Firmware 2.0, you can set the number of significant digits after the decimal for the Analog Voltage readouts on the
Status page, as well as set the temperature units.

SENSOR SETUP

14 of 21 January 25, 2017
Sensor Setup Notes
The admin user can set custom names for each input or output. Factory set names will be supplied, but they can be re-
written to be more descriptive, or to manage larger systems. Alarm colors can be set here to represent the proper
logical state for your system. If any of the name fields on the left are left blank, the channel will be hidden on the status
screen. REV 2.10 firmware added the ability to change the name of the AC and Temperature channels.
Analog alarms are set up in the “Alarm Setup” screen. See the “Alarm Setup” section for more information. Analog
channels #1 thru #4 are the only ones wired and configured in the RLP-2024BBSCLVD-MU.
In the RLP-2024BBSCLVD-MU the Digital Output 1 is an alarm output, and Digital Output 2 controls the ON/OFF state of
the power supply. The user must be logged in as the admin or control user to control the digital outputs. The digital
outputs can be controlled by the buttons on the status page, mobile page, or via SNMP on the RLP-2024BBSCLVD-MU
Optionally, they can be automatically controlled by connecting them to an alarm on the “Alarms” screen.
In Revision 2.2 Firmware (see Device Setup screen) the user can enter text to change the user meaning of the digital
output states, and there are 3 color options for the buttons. “Active” means that the digital output MOSFET is
conducting. Digital Output 1 can also be configured to output a positive or negative pulse with a duration between 0.5
second and 60 seconds. Pulse width value is chosen from a dropdown list.
Additional settings for digital input alarms and emails have been added in Firmware 2.3. Digital Input #1 and #2 are the
only ones wired and configured in the standard RLP-2024BBSCLVD-MU. Digital input #1 is wired to the Alarm IN on the
back panel, and Digital Input #2 is wired to the DC-OK for the power supply.
Firmware 2.4/2.5 added the ability to alarm and send notifications for the digital outputs.
Revision 2.10 firmware also added the ability to apply a running average to any of the analog channels, including the AC
voltage and Temperature monitors. The number of averages is selected from a dropdown list for each channel. This can
be used to quiet any noise or false alarms due to transients

ALARM SETUP

16 of 21 January 25, 2017
Alarm Setup
This screen is for setting up analog and digital alarms.
To set up analog alarms, first you must select the alarm channel to set. This is accomplished by selecting the custom
name of the channel in the dropdown box next to the “Analogs” label. For example, we are looking at the settings for
the “Module #1 Amps” channel in the screen above. Firmware 2.0 includes additional settings for alarms.
The alarm will be active when it passes through the upper or lower alarm threshold, and will become inactive when the
measurement returns to the recovery threshold.
Note: The maximum temperature of the temperature sensor is +300 F. The low range of the sensor is about +36 F.
Firmware 2.3 added the ability to log alarms. The “Log Alarms” setting on the “Device Setup” Page, is the same as the
“Global Settings”, “Log All Alarms” setting on this page.
Digital output alarm conditions can be set to “Never Alarm”, “Alarm on <user name for inactive state>”, “Alarm on <user
name for active state>”, “Alarm on (both states)”.
E-mail notifications can be set for each analog alarm threshold and its recovery threshold, as well as digital alarm
conditions.

Revision 2.10 of the firmware added the ability to set a duration for the analog and digital input alarms. Selecting a
duration from the dropdown list means that the alarm condition must be sustained for this length of time before the
alarm is triggered. This applies to alarms shown on the status screen, email notifications, and traps when the alarm is
set, and when it is cleared.

CONDUCTOR PRETREATMENT
All kinds of copper conductors can be clamped without treatment. DO NOT solder tin stranded conductors. The solder yields
and fractures under high pressure. The result is increased contact resistance and excessive temperature rise. Additionally, corrosion
has been observed due to the fluxes. Notch fractures at the transition from the rigid tinned part to the flexible conductors are also
possible. Ferrules can be used as a protection when wiring stranded conductors. Copper ferrules prevent the current transfer from
being influenced by dissimilar metals and remove the risk of corrosion. Always use the correct tool to crimp the ferrule.
