Introduction

The Data Logger/Monitor has been designed to operate on 12V, 24V, 48V and 110V battery systems, with optional inputs for higher input Voltages, up to 550V. The Data Logger/Monitor is completely powered from the Batteries, and therefore a mains supply is not required. Therefore tests are not terminated part way through by a temporary mains power outage. The unit is lightweight and is completely portable. The Data Logger/Monitor may be left on site, unattended, for extended periods of time for data collection. Or used permanently as a Monitor / Alarm system.

The standard Data Logger/Monitor is built to accept upto 9 inputs from Cell / blocs and comes complete with a Master Input Module. (There are options to increase the number of channels up to a total of 127 Channels at the time of ordering). These can all be logged together with “Temperature”, “Battery Discharge Current”, “Overall Battery Voltage” and “Total Interconnection Voltage”. As well as recording all of the inputs, the relative time is also logged, e.g. 1 minute, 30 minutes, 60 minutes etc..

The Data Logger/Monitor has two modes of operation,Battery Discharge and Monitor Mode. In Battery Discharge mode the unit will log all cell/bloc Voltages at programmed intervals as well as “Temperature”, “Battery Discharge Current” and “Overall Battery Voltage” and “Total Interconnection Voltage”.

The logger is initially set up via a local or remote Laptop / PC, after which the Laptop may be disconnected and the logger will continue to function in its present mode.

In discharge test a Laptop may be reconnected after the test has finished and the data collected downloaded to the laptop.

In Monitor mode the logger will continue to activate its alarm output contacts should an alarm condition occur. The Laptop may be reconnected at any time for real time updates of all readings and alarm status.

Benefits

Easy to set up.

Intuitive to use Application software.

Selectable "End Voltage" from 1.55V to 1.90V per Cell, (or equivalent for blocs), which effectively becomes a LVD function with output to disable a Manatronics Electronic Load. Every Cell / bloc ismonitored for "End Voltage", which prevents deep discharge and possible battery damage.

Common input modules for 2V, 4V, 6V and 12V blocs. (i.e. no need to buy/change/store modules).

Designed for 12V, 24V, 48V and 110V Battery Systems.

Features

Fully programmable Full and Pre alarm conditions with Voltage free outputs, suitable for connection to a SCADA (Supervisory Control and Data Acquisition) system.

Alarm log to view previous alarm conditions with time/date stamp.

A USB Port for connection to a Laptop or PC.

Option for Ethernet connection can be connected via a Router to the web for remote control / access.

May also be fully controlled remotely from anywhere in the world via a dial up modem and either land line or mobile phone. All parameters may be set / monitored. Even a full discharge test carried out with full data download.

Selectable sample rates from 10 seconds to several hours

Hardware

Non volatile memory (i.e. data is retained even when disconnected from the Batteries).

Completely powered from batteries, 5W drain, (7W with Ethernet). No mains supply required.

ESD protection on all inputs.

OverVoltage Protection on all channel inputs.

Protected against accidental mis-wiring, (i.e. no high fault currents).

Remote enable / disable (suitable for UPS control).

Software

Supplied complete with all software necessary for control and comms, i.e. National Instruments® front end operating in Windows®. (Installation from CD ROM).

Real time Alarm status displayed on the Application software.

Alarms may be reset or armed remotely.

Reports in Tabular or Graphical using the supplied software Auto Graphing facility.

Simple output format suitable for “Excel”® spreadsheet or similar.

Battery Discharge Data and Alarm logs may be saved to HDD or FDD, after download to Laptop or PC.

The standard unit can store about 10,000 cell/bloc readings with an option to expand this to about 40,000 readings.
