WARNING:
High voltages exist inside the monitor system components and on the terminals.
Calibration must be performed only by technically qualified persons.
Observe electrical safety precautions when removing and installing equipment covers
and when connecting leads and making adjustments.
4.6 Shipping, Storage, Normal Use Protection
Protect the system from physical impact during normal use or storage, and when necessary,
provide protection during shipment between test sites.
5 Product Overview
The BDS–40 is a stand–alone monitor for UPS applications and is designed for use with UPS
battery cabinets. What sets Albércorp. monitors apart from others is their ability to provide early
warning of battery problems. The monitor checks the state of health of each cell by performing a
proactive resistance test, a reliable predictor of battery performance. In addition, to indicate
immediate battery health and monitor status of a given location, the system reports to a Central
computer i.e. a generic PC, displaying status screens.
Using polling and data transfer algorithms, the Battery Monitor Data Manager software program
allows the user to manage over 1000 monitor systems from a central PC. Data is stored in the
computer’s database for later analysis and reporting. At any time, service personnel may call a
battery location from the Central computer or a remote location, or directly connect to the
monitor.
The Data Manager string and monitor status indicators make central battery monitoring easy.
Terms such as Discharging, Alarm, or Warning for string status or Active for monitor status
quickly summarize events. Conditions reported to the Central computer display as a list, to
identify trouble spots easily. The system also features several methods of automated reporting
of alarm occurrences, such as contacting key personnel via a pager, email, or fax.
Flexibility was a major design consideration. Since the monitors are stand–alone units with no
external computer needed, a primary protocol using MODBUS ASCII was selected to allow the
user to incorporate the monitor into large–scale facility monitors. This allows third–party
interfaces to access all the stand–alone features of the monitor, yet leaves the advanced
features of the Data Manager remote communication software available for service personnel.
5.1 Normal Operating Mode
In normal mode, the system scans all parameters in one to five seconds, depending on the
configuration. As readings are taken, they are compared to user–programmed alarm levels. The
monitor can then call a Central computer and energize an alarm contact if a parameter exceeds
a level. Front panel LEDs indicate scan and alarm status, and alarm events are stored in
memory for future analysis. The BDS can be programmed for critical and maintenance alarms.
5.2 Discharge Mode
If a discharge is detected, the system goes into a data logging mode and stores battery voltages
and discharge current into a discharge record.
