Selecting the preferred charging mode for a system start
The power supply system can be configured so that all of the buffer modules and battery
modules are charged up to a specified level before the power supply system outputs are
activated.
If the setting is activated at a UPS module, then this applies to the complete power supply
system. If there is no UPS module in the system, then this setting can be activated in the
REMOTE operating mode (TIA Portal, web server, OPC UA).
The switchover is made at DIP switch
② with the designation "PRE CHRG", see Section
"Operator controls (Page 43)".
When delivered, the "PRE CHRG" DIP switch is in the "OFF" position (charging operation
not preferred).
Only activate outputs after a specified charging state has been reached
Set DIP SWITCH "PRE CHRG" at a UPS module to the "ON" position (right) to give
preference to charging operation; the outputs are then only activated when a specified
charging state is reached.
Set DIP switch "PRE CHRG" at all UPS modules to the "OFF" position (left) to activate the
outputs immediately after the system has run up.
