6A.4.2 External control supply management
With the new parameter Control Supply Line [06.09] = External, it is possible to enable the external control power management that provides, when
required, masking of the main power check protections.
:
Minimum DC Voltage Protection
UnderVoltage Protection bus DC (programmable threshold)
Input phase loss (programmable b
Input Single Phasing [11.18])
Main power checking is enabled by DI – DriveEnable:
DI- DriveEnable = Close main power check enabled
DI- DriveEnable = Open main power check disabled
When the DI- DriveEnable is open the protection Main Contactor Fault will be delayed for 60 [s] in order to avoid this protection at the shut down of
the main power. If after this time the voltage of the DC bus doesn’t drop below the threshold (UV-VDC Set Point [69.01]), the protection will become
active.
