QC-APS3-15 auxiliary power supply
The control of the soft-start activation is established via the auxiliary
contact of the - KM1 external power contactor and the - KA3 relay contact
controlled by a PLC output. For both, it is possible to supply the +24 V DC
to the internal windings of a relay, via the Da+/Db- terminals of the X33
connector, thus enabling the soft start of the power supply. All information
regarding the X33 connector can be found in section, 4.6 EXTERNAL
