5.7.12 Program and Parameter Memory
5.7.12.1 General Information
The illustration shows the positions of the
memory card slots, interfaces, EEPROMs
and internal flash memory.
The printed circuit board houses the digital
control electronics and the processor, the
flash program memory, EEPROM parameter
memory, realtime clock, battery, LC display
and buttons.
The interfaces for 2 CAN networks, serial
data remote transmission (optional), USB or
Ethernet, USB host and USB device, and the
serial selection of a frequency inverter via
DCP are also mounted on this board. In
addition, the bp308 has 8 inputs and 16
calls, which can also parameterised as
inputs or outputs. The lift program is stored
in the flash memory. All lift-specific parameters such as type, stops,
doors, times, parking landings, etc. are safely stored in EEPROM.
5.7.12.2 Exchange
To exchange the EEPROM use a special EEPROM snag and draw
the EEPROM from the socket at right angle. Insert the new EEPROM
at right angle and press it into the socket while applying slight pres-
sure. You must ensure that the marking (groove) is in the correct
position to insert the component the correct way round!
I
NFO
!
As the pins of EEPROMs are at risk of bending or breaking off, it is
strongly recommended to use a snag as an appropriate tool .
A
TTENTION
!
The guarantee expires if program changes and subsequent changes
of the lift controls are carried out without assistance of the BÖHNKE
+ PARTNER service team .
