Yes, the programming for the permanent voltage is really easy and works for both flatpack 2 HE and Flatpack S (2 types i used)
Just 2 commands are needed.
remember to use extended CAN-BUS code (29 bit) !!
first command is an 8 byte command to log into the unit. send it to adress 0x05004805 and the command is formed by the serial number with two 00 bytes added. the serial number should be on the unit. example from my stack : 141471110820 is the serial number. Command is 0x05004805, 14 14 71 11 08 20 00 00
second command is a 5 byte command to address 0x05019C00, the command is 29 15 00 44 16 (all Hex)
Important is that the second command is sent to the power supply within 8 seconds of the first, otherwise the PSU will think it has lost connection. You will have to issue the first command again to 'log in'
Now wait 30 seconds without sending any commands but keep the power supply connected to mains (this is an important step)
after 30 seconds, disconnect the power supply from mains for another 30 seconds.
Restart the power supply and it should default to the output voltage you set in the second byte.
The end voltage is contained in the last two byte of the second command (44 16).
To calculate the output voltage first reverse the 2 numbers (1644) and convert that from HEX to decimal. This will give you 5700. This is the end voltage in centivolts. divide that by 100 and you get 57.00 Volts.
The flatpacks don't go up higher than 57.60 Volts (1680 HEX) anything higher will result in an end voltage of 57.60 Volt.
in short :
send : 0x14, 0x14, 0x71, 0x11, 0x08, 0x20, 0x00, 0x00 to address 0x05004805 (depends on the serial nr of the unit)
send : 0x29, 0x15, 0x00, 0x44, 0x16 to address 0x05019C00 within 8 seconds
wait 30 seconds
wait 30 seconds
plug in power.
Default voltage should be 57.0 volts
