Delay in the thyristor disabling
4.4mS +/- 10%
From the above table, considering the example, a delay of 1.1mS is selected by setting:
S1.1 OFF - S1.2 ON - S1.3 ON - S1.4 OFF.
N
!
OTE
With S1.1 ON the delay circuit for the thyristors switching off is disabled. In this case when
a mains dip occurs, the thyristors will be switched off; once mains dip is elapsed, the capacitor
precharging sequence will be executed again (default configuration).
3.3 USE OF S2 SWITCH
Via the S2 switch it is possible to select the undervoltage threshold, which depends on the AC main voltage of
the converter. Dip S2.4 not used
Power supply voltage
460V -10%÷480V+10% (Default)
400V +/-15%
( 230 +10/-10% )
3.4 USE OF S3 SWITCH
The S3 switch is able to set the precharge time for the DC link capacitors (the higher precharge time, the
lower will be the current during the precharging phase to the supplied capacitors).
Time (Seconds)
11 S +/-15% (Default)
Use the following way to select the precharge time:
