3. Overview
As batteries age their capacity slowly deteriorate until they need replacement. Additionally, battery
capacity can be affected by extended operation under adverse conditions of high or low
temperatures, high discharge rates, under charging (in particular if left in a completely discharged
state for weeks or longer), charging voltages higher than recommended (this condition immediately
starts generating surplus hydrogen gas for which even Sealed Lead Acid Batteries are forced to
vent).
Although a battery’s state of charge can be inferred by monitoring the battery terminal voltage while in
standby mode, this voltage will not give an indication of actual capacity. Furthermore, a battery that is
marginal may not be detected until it is called upon to perform, at which point it is too late to prevent a
system failure. For a battery connected to a charger that maintains a float voltage, neither condition
can be checked.
In these cases, the BTRM is designed to evaluate battery capacity transparently to system operation
and provide network-based notification should a battery fail, or its capacity drop below a specified
level. This also has the advantage of allowing batteries that exceed their nominal lifetime to remain in
service, provided they meet capacity requirements.

Remember to select BTRM operation voltage on the Port Options page or selecting via one
of the supported protocols (DNP3/Modbus/Snmp) for proper operation.
The battery bank must be connected directly to the BTRM, such that the BTRM can power
the load from the Battery without any additional power source in circuit in order to perform
the battery capacity test.
4.4. Load (+/-)
The battery bank must be connected directly to the BTRM in order to perform the battery
capacity test.
4.5. Alarm Connector (+/-)
BTRM300 & BTRM400 have 4 Channels of ground referenced IO.
All 4 channels can be used to sense and monitor 0V to 60V.
Channels 1 and 2 can be used to activate relays, audible indicators, or lamps by pulling the
IO pin to ground under certain alarm conditions.
Both Channels 1 and 2 contacts are normally open when power is off. The user can select
normally open or normally closed under an alarm condition.
Do not exceed the contact maximum relay ratings of 60 Volts, 80 ma. Do not use to directly
operate AC line connected equipment.
5. Basic Setup
Connecting unit to a PC
Notes on accessing a BTRM over Ethernet: Technically you should be able to plug the device into
your current network, regardless of how your current network IP addressing is set up and be able to
reach the BTRM’s Status and Setup web page by entering its IP address (found on the BTRM front
label) in a Web Browser on a local computer. However, in practice, not so easy, due to a wide variety
of possibly incompatible network addressing and firewall configurations. These difficulties occur most
often if someone else has set up the network settings, and in particular where these settings are
“managed” by software installed on your computer by your internet provider or corporate IT
departments.
To avoid these potential network issues at the initial evaluation stage it is best to connect both your
computer and the device to a hub/network switch (one that is not connected to the rest of your
network) or directly connect your computer to the BTRM with a cross-connected Ethernet cable.
Initial Power up to set IP address
To power up the device, connect the battery to the BTRM. Power up the power supply and battery
charger. The BTRM starts in self-test mode for 5 to 15 seconds. PB1 and PB2 push button LEDs will
blink.
Once the device is power up and cabled to the Ethernet, the GREEN LED will illuminate on the
Ethernet connector and startup should be complete within 30 sec.

Accessing your host computer’s network settings
From the start button select Control Panel -> Network and Internet -> Network Connections
• Select the adapter that you plan to use and from the File menu, select properties.
• This will bring up the properties window, shown on the right.
• Scroll down to the Internet Protocol Version 4 (IPv4) item, select it, and then select “properties”.
• This will bring up the window to allow manual configuration of the network adapter’s IP addresses.

BTRM Battery Test Remote Monitoring System – User Guide V3.2 | ã2021 Ventev | LIT SKU: 09834

Setting IP address information for BTRM default
Using a direct connection to the device with a cross connected cable or using a network switch (hub),
use the manual IP settings shown on the right. This property dialog can be found in the TCP/IP
properties, which is a sub dialog of the Network Connections Properties, both found in Control Panel
Network Connections.
(Typically, the default gateway and DNS server need not be entered.)
If using a router, check your local area connection settings to see if the router gateway address is the
same as the default device gateway of 192.168.1.1. If it’s not, you will need to use a direct connection
as described above to change the device gateway address to match the router’s gateway address.
Verify IP address information
For the initial configuration of the BTRM and to change Network IP settings for placement in an IP
based network you will need to connect the BTRM directly to your PC. Once connected to your PC
you will be able to configure the BTRM to match your network settings.
You will need the following information from your network administrator to add the BTRM to your IP
Network:
• IP Address – we recommend using a static IP address for the BTRM
• Gateway – what is the IP address of the Gateway of your network
• Subnet Mask – what is the mask of your network
• Primary DNS – IP address of the primary DNS server for your network
Once you have your connection made with laptop or PC you will need to record your IP address and
verify connection to the BTRM.
NOTE: It may be necessary to give your PC or Laptop a static address to access the BTRM default
network.
Example: IP Address: 192.168.1.200
Subnet mask: 255.255.255.0 Finding your IP address in Windows 10

Alarm connections are sets of normally open/closed contacts. These contacts are isolated
from the BTRM power source, and do not provide power. They can be used to alert the
Network Operations Center by connecting the alarms to your systems existing alarm
signaling pairs. Alternatively, the alarm contacts can be used to operate external DC relays
that then can be used to control alarm lights or audible alerts. Provided that the contact
ratings (60V, 80 ma) are not exceeded.
6.5 Clearing Battery Test Data
To clear test data from the BTRM memory, press and hold button PB2 for 15 seconds until
the LEDs flash.

7.3 Battery Test Page
7.3.1 Type 1 Test
This test runs the attached load for a short period of time, dependent on the load power
requirements and the battery Ahr rating. This can be anywhere between 1 hour to 4
hours. At the end of the test discharge profile of the battery is analyzed to give an
expected run time (ERT)to low battery. This ERT is then compared with the customers
minimum runtime (MRT)enter on the Type 1 settings page. If the battery’s ERT does not
meet the MRT, capacity is flagged as LOW, and relevant alarms are triggered.
7.3.2 Type 2 Test
This test runs the attached load for customer determined period or until a customer
determined cutoff voltage is reached. The test result in both cases is the test duration
and the Battery Voltage reached at test termination. This test can be flexibly used
anywhere from being a short test to validate the system works on a daily basis (a
requirement in some industries), or full test of the batteries capability by setting time to
maximum, and battery cutoff to the lowest battery voltage allowed for system operation.
Again, if the test conditions set are not met, relevant alarms are triggered.
