FW095-0131: S3T60_0131.hex      [03/07/2025] CRC32:[B0608202] Standard production

I   - Increased filter time for battery overvoltage diagnostics when switching from charge
      to floating state (to avoid false warnings [F19] and [F20]).
I   - Increased resolution of the manual bypass switch debounce filter, to avoid false
      signals in case of auxiliary contact problems.
I   - Added management of the parameter "Power walk-in start delay" to make mains return
      verification time configurable.
T   - Added check for "SEQ_BUSY == 0" before generating the "OMNG_UNLK" pulse.
T   - Added a redundant safety feature to the battery charger current limitation
      calculation to avoid the possibility of out-of-range value.

FW095-0129: S3T60_0129.hex      [04/04/2025] CRC32:[2FB04FE2] Standard production

Note: NOT RELEASED FOR STANDARD PRODUCTION

I   - Increased ICBAT-Max saturation to better manage a number of batteries greater
      than 21+21 in the second level charge phase.
I   - Added backfeed test mode configuration to ensure full compatibility in case of
      special loads.
B   - Fixed a bug in the communication protocol (R/S command) that in some situations
      could cause a false overtemperature alarm.
T   - In ECO mode, the request for inverter intervention due to VOUT control must also
      be made by the slaves. Currently, slave UPSs request intervention only for MIN_R
      control.
T   - Introduced BYP_FLAT check for one of the backfeed test triggers to make the system
      more filtered.
T   - Improved the logic of the additional regulator during the backfeed test.
      Now it remains active during this phase.
T   - Increased the additional regulator gain corresponding to 100% from 0.6 to 1.0.
      This allows for higher default values of the "Resonant scale" parameter from
      100% to 167%.

FW095-0124: S3T60_0124.hex      [25/03/2024] CRC32:[2F60BF57] Standard production

I   - Improved the power recirculation mode controller, to reduce input current
      absorption.

B   - In case of UPS in parallel and without batteries, if the System has a totally
      shut down of the input mains of both UPS, both UPS show the message "Load Off"
      and of course, we loss the output voltage, but if before that the UPS are
      completily off the input mains returns, both UPS don't restart by itself.
      It is necessary to restart manually both UPS with the panel command.

B   - If during a shutdown with absent input voltage, the mains returns before the
      time expires, at the end of the time the UPS output always remains on and the
      correct procedure of switching off, waiting for 10sec and switching back on is
      not carried out.
      
T   - Added an average on the temperature measurements of the Boost and Inverter
      power modules.

FW095-0123: S3T60_0123.hex      [09/11/2023] CRC32:[79845F16] Standard production

I   - Improved Input contact fault detection.
I   - Improved Battery charger short circuit detection.
I   - Improved Backfeed check.
I   - Added 10s delay before re-start.

B   - Fixed bug related to Latch bypass detection when redoundant Latch bypass
      configured and not active.
B   - Fixed bug related to start when mains 3 phases are detected and are good.
B   - Fixed bug related to start from battery.
