In such conditions, as soon as a mains failure occurs, if the selector is on AUTO the users are switched on the generator.

  • Page 31 Normally, with the board in the MANUAL mode the users are switched on the mains. Only if the engine is running, if the generator is “present” and the delay before the supply has passed - P06 (or if the temperature exceeds the minimum threshold set with P55), the operator has the opportunity to switch them on the generator.
  • Page 32 4. The “START” output (terminal 20) controlling the generator set starter, is enabled. The output is kept for the time set with the parameter P08 or until the engine running recognition. In this phase the display “MULTIFUNCTION” shows the message “STA”. If the engine gets started phase 6 will follow, otherwise phase 5 will follow (unless the starting attempts have ended, 5.
  • Page 33 The boards waits until the mains gets “present” and all the other start requests get off (see par.5.1.1). Further, the arising of new faults of the generator set is checked. In sequential order there are:  Opening of the generator set contactor (closed contact at terminals 58-59) ...
  • Page 34 The board is able to execute the true r.m.s measurements on the generator’ voltages and currents as well as the active, reactive, apparent power and power factor measurements of the system when it is powered by the generator. In addition, it manages an energy meter for the power supplied by the generator set.
  • Page 35 The energy meter managed by DST4600A counts the energy supplied by the generator set. It has an internal resolution under 100 Wh but it is displayed in kWh. It is updated every second.
  • Page 36 Starting from 08.00.24 version, it is possible to avoid black-out due to KR failure. In case of such failure the user power line remains unsupplied if the grid is present. Using this function is possible to guarantee power availability at user level. To use this function the system must be configured as following: ...

  • Page 38 From the software release 08.00.25 is it possible to order as option the second serial port of DST4600A board. It is then possible to connect to this serial port one expansion board provided with 32 digital outputs or 16 outputs and 16 inputs. The outputs can be used as additional remote signals.
  • Page 39 “OUTPUT 1” output and the “F49” warning are deactivated (the “F49” warning is still present on the DST4600A panel if not acknowledged). If the active power is between the P56 and P58 thresholds, the maximum power status and the “OUTPUT 1”...
  • Page 40 P56. Starting from SW revision 08.00.24, it is possible to install in DST4600A boards a Real Time Clock option (RTC). The option is equipped by a lithium battery that let the watch running also without supply.
  • Page 41 Once in RTC display mode (see previous paragraph), pressing “MODE/ACK” the RTC setting mode is entered. Display “F” will show one of the following messages, while display “A” will show the proper value:  “SEC”: seconds (valid value 0 through 59) ...
  • Page 42  The parameter P19 determines the duration of the test operation of the generator set. If during the programming you change the value P18 the period count will restart from zero in the moment in which you’ll exit the PROGRAMMING procedure. The automatic periodical test is disabled if at least one of the two parameters is equal to zero or if RTC based periodical test is enabled.
  • Page 43 The correspondent SW version for the DST4600A/P is 12.05.22. The input function is specialized for the parallel fault condition. The only difference between DST4600A and DST4600A/P is the default of the P65 (ALARM2 (terminal 02) filter time): for DST4600A/P is 180s instead of 1s.
  • Page 44 In the standard version, this terminal acquires the high water temperature alarm. In this version, it acquires the “engine in threshold” status, and so the high water temperature alarm is disabled. Only for this version, the board can activate a block (“F40”) when the KG is closed and the signal on terminal 10 becomes inactive, with a fixed filter delay of 0.5 seconds.
