7.3.1 SRAM Battery (RTC)
The SRAM on the interface board is buffered by a lithium battery (for technical data see section
"Lithium Battery").
SRAM
The content of the SRAM can be secured with MS-DOS drivers for SRAM and FlashPROM
memory cards or standard PCMCIA card drivers available from B&R. These can either be found
on the Provit Drivers & Utilities CD-ROM 5S0000.01-090 or downloaded directly from B&R's
homepage (www.br-automation.com).
Changing the battery
1. Disconnect the power supply
2. Touch the housing or earth connection (not the power supply!) in order to discharge any
electrostatic charge from your body
3. Remove the housing cover (see the section "Removing the Housing Cover")
4. Battery position
5. Remove the battery from the holder by pulling the removal strip (don't use uninsulated tools -
risk of >short circuiting). The battery should not be held by its edges. Insulated tweezers may
also be used for removing the battery.
