Note: used only for special production

N  - Added management of a SWBAT auxiliary input configurable on INPUT #3.
     Closing the contact (pin 7 and pin 15 of AS400 port) the UPS signals the
     anomaly "[A42] BATTERY SWITCH OPEN".
     To enable the function you must use GpConfig version 1.5.6 or higher
     (External I-O->Input contact->Input 3 mode->SWBAT status).

N  - Added a function to command the opening of an external battery switch
     in case of EPO or Remote_OFF command, using an output contact of the
     MultiCom 382/392 card. You can select the function on the "Output 4" of the
     MultiCom 382 card or on the "Output 1 to 8" of the MultiCom 392 card.
     If the function "SWBAT open cmd x EPO" is selected, when the command EPO is
     actived, an impluse of 0.5sec is generated and then the output of the UPS
     is turned off.
     If the function "SWBAT open cmd x ROFF" is selected, when the command EPO
     or the command Remote_OFF is actived, an impluse of 0.5sec is generated and
     then the output of the UPS is turned off.
     To enable the function you must use GpConfig version 1.5.6 or higher
     (External I-O->Output contact->Output mode->SWBAT open cmd x ...).

I  - Added the possibility to reduce the short-circuit time up to 200ms.
     The default value remains of 500ms.
     To change the time you must use GpConfig version 1.5.6 or higher and
     you must insert the password for advanced service.

I  - Added management of the card MultiCom 382 also for CSS.
     To enable the function you must use GpConfig version 1.5.6 or higher
     (External I-O->I/O card model->Multicom 382 [4 out]).

T  - The Customer_code is now initialized to zero ("Not personalized").

N  - Added management of the new slot I/O card MultiCom 392. To enable the use
     of MultiCom 392 and to configure the outputs, you must use GpConfig
     version 1.5.1 or higher (External I-O->I/O card model).
N  - Added a new set of serial commands to force the UPS mode: On line, Eco,
     Smart active, Stand-by off, On bypass, On battery, Battery charger off,
     Disable bypass and Battery charger current reduction. These commands are
     useful for the management of the smart grid or to control the UPS in remote
     mode.
N  - Added a new configuration to make possible the supply of the load even if
     only the bypass line comes back present (mains not present). To enable the
     function you must use GpConfig version 1.5.1 or higher (Bypass->General->
     Auto bypass on).
N  - Added a redudancy control for the battery voltage measures and for the bus
     DC measures. This control is added to avoid damage to the batteries and to
     the UPS in case of failure of a board. the problem is signaled by the new
     messages "BATTERY MEASURES ERROR [F33]" or "VDC BUS MEASURES ERROR [F39]".
N  - Added a function that allows to program the scheduling of turn-on and
     turn-off using the internal clock of the UPS. To configure the time, you
     must use GpConfig version 1.5.1 or higher (Basic->Timer).
N  - Added the possibility to configure the input 3 function to active
     Stand-by OFF mode.

I  - Added language Swedish (Svenska) on the firmware version second language
     set (_L2).
I  - If the alarm "Bypass phase reversed [F12]" is present, now is not possible
     turn-on the UPS.

T  - In debug mode (using debug key) the second level of the battery charger is
     disabled. This is necessary during the calibration of the battery voltages
     because in this phase the voltage must remain stable.

     later (new panel "Battery Test").

I  - Added language Portuguese on the firmware version second language set (_L2).
I  - Added the configurable parameter "Power walk-in Start Delay" that allows to
     delay the switching of the input stage (after a period of battery operation)
     ,and therefore to avoid peak current absorption on case of more UPS powered
     by one source. You are enabled to change configuration only with software
     UcomGP 1.4 or later.
I  - Increased overload time on bypass for values above 150%.
     The time changes from 2sec. to 3sec. for overloads between 151% and 200%.

B  - Fixed some russian language translations.

T  - Changed the control of the opening of the sectioning switch of the neutral
     for UPS from the TT5 family. In case of opening of the switch the load does
     is no more turned off as with previous firmware versions, but instead is
     powered by the bypass line (if present between correct values).
T  - Improved the registration of the historical data for overload event in case
     of overloads with times lower than 2sec. (filter time for overload
     signaling).

     serial protocol (command G / N) instead of the capacity of internal
     batteries alone.
B  - Added the automatic bypass re-enabling in case of transition from
     configuration with bypass disabled configuration (Frequency converter,
     Bypass disabled, Stand-by off, etc.) to a configuration of with bypass
     enabled, without the need to go from stand-by status.

T  - Added in the serial protocol the management of 'SL' command for software
     identification and disabling of the following commands: 'SP', 'SM', 'ST',
     'SO', 'SR' and 'CF'. With this improvement now is not possible use old
     software (UpsTools, Configurator 1.2 or previous) to change configuration.
     You are enabled to change configuration or to calibrate UPS only with
     software UcomGP 1.3 or later.

N  - First revision for UPS 60kVA and 80kVA (TT5 family)

I  - Added the recording of historical information about the parallel system.
     The information can be viewed with software GpHistory 1.3 or later.
I  - Adding the parameter enabling the filter of the measure of input "Input
     filter".
I  - Perfected control curves for the test battery for batteries with a capacity
     greater than 65Ah.
I  - Using the actual value (not averaged) of the measures of the voltage bench
     (Vdc+ and Vdc-) for recording on the historical record.
I  - Elimination of the event return to a normal state as a trigger for the
     historical record. Adding new trigger events for registration.
     
B  - Fixed issue where the change of the configuration "Synchronization filter"
     and "Input filter" sent to a Slave UPS of a parallel system, was performed
     on that UPS, only after turning off completely and then back on the UPS. On
     all other UPS's system, however, the change was implemented in real time.
B  - With function "Bypass active in stand-by" active occur continuously
     registrations in the historical data. The memory was always busy and then
     attempts to access from the outside gave negative results.
B  - Improved algorithm for the recognition of the triad threephase of bypass
     not correct to eliminate false alerts that could have occurred in special
     cases, during the return of power.

T  - Adding a filter on the registration of anomalies of overvoltage and
     undervoltage of the input voltage.
T  - The communication speed is fixed to 9600 for the communication slots 1 and
     2 in case of debug key inserted.

N  - Added the management of the options KIT CHARGER 10A (for UPS from 10kVA to
     20kVA)and KIT CHARGER 20A (for UPS from 30kVA to 80kVA).

I  - Introduced different curves, according to the UPS model and UPS power, for
     the reduction of the maximum current of the battery charger, in case of
     low input voltage.
I  - Added a configurable parameter to set the time used in battery recharging
     in case of battery custom charging alghoritm (ie. for NiCd battery).
     If the parameter is specified the recharging voltage is maintained for the
     specified time.
I  - Changed the alarm delay time and the shutdown delay time when, in parallel
     systems using a common single battery, a unit operates from battery while
     the other units are operating from main line.
     The message of fail will be displayed with a delay of about 20 sec. (5 sec
     before the modification). In the same unit, the inverter will be switched
     off after a further delay of 100 sec. (15 sec. before the modification).
I  - Eliminated the automatic transfer of the parameter of Autonomy limitation
     time from Master to Slave. It's now possible to set different time between
     UPS's of the same parallel system.

B  - Introduced different battery discharge curves, used to calculate the
      estimated autonomy time, for battery over 40Ah.

N  - Added the Cyclic Charging Alghoritm.
     It can be selected using Configurator software.
N  - Added the Battery Manual Charge function to equalize the battery bank.
     In case of a Parallel common battery system the Master synchronize the
     charging voltage and charging current of all battery chargers.
     It's possible to send the command using Configurator software.
N  - Added the possibility to configure the Battery Charging Alghoritm
     (One level, Two level or Cyclic).
     In a parallel system the selected configuration is sent to all UPS.
     In case of a Parallel common battery system the Master synchronize the
     charging voltage and charging phase of all battery chargers.
     The configuration can be done using Configurator software.
N  - Added a special serial command to change actual output voltage in real time
     Voltage from 160Vrms to 250Vrms are accepted.
     It's not possible use this command in parallel mode.
N  - Added a new screen (page 1/4) that show in graphical mode the UPS status.
     The window describes with a synoptic the status of main blocks of the UPS.
     It's available for all the languages.

I  - Added the release index in the file name (i.e.: _0214).
I  - Added a control to disconnect the bypass if it's out of range and the UPS
     is in Lock-Load on Bypass state.
I  - Added the configuration External input for Power share and Output contact
     functions linked to the Input #3.
I  - Changed the logic of the bypass request in parallel mode to have better
     performance in dual input configuration.
     It's possible to select dual input configuration using Configurator softw.

B  - Revised the start of the battery charger current.
     With the previous firmware, at the power up and after the precharge phase,
     the battery charger current goes to the required value slowly (with a slow
     ramp); after the modification the current goes to the required value in a
     few seconds.
B  - Corrected the setting of the nominal output voltage with the Chinese
     leaguage.
     With the previous firmware, when user change from not Chinese languages to
     Chinese language and vice versa, and if he never entered in the
     configuration men, the nominal output voltage changes from required value
     to 200Vrms.
B  - Corrected the mulfuncion of power-share configuration Normal status.
