2.2 CHARGER COMMON PARAMETERS SET UP
2.2.1 General
Writing into the RAM leads to modify the charger operating parameters.
In this paragraph, we present the most common charger settings. For more information, please contact the factory.
RAM registers are coded in 16 bits.
In order to write into the Ram: send the password to the address (27 hex; call technical support for password).
When the password is accepted, each register with state (W) can be modified.
WARNING:
Only qualified and trained personnel can access this mapping.
Parameters modification with wrong information may lead to major defects and failures if wrong data is used.
2.2.2 Voltage or current settings
In order to modify the float voltage, write the required value in register (0E hex) (Refer to Note 1, for the byte format to
send). For equalize voltage, the address (0F hex) is to be used.
In order to modify the float limit current, write the required value in register (10 hex). For equalize limit current, the
address (11 hex) is to be used.
2.3 OPERATION MODE MODIFICATION
To switch from float, to equalize, send (0001 in binary) to bit 3, 2, 1 and 0 respectively into the register (26 hex), (Refer
to Note 21).
To switch from equalize, to float, send (00010 in binary) to bit 3, 2, 1 and 0 respectively into the register (26 hex), (Refer
to Note 21).
2.3.2 Formation mode
To start a formation mode send (0100 in binary) to bit 3, 2, 1 and 0 respectively into the register (26 hex), (Refer to Note
21).
