Rotary coding
buffer time
Interruption of the output voltage (pin 13)
A wire jumper on the signal connector ④ between pin 13 and pin 10 is used to enable/disable
the interruption of the output voltage, after the set buffer time expires, for the parameterized
time (default value 5 seconds) when the line supply returns during the buffer time. The
default value can only be changed for devices with USB or Ethernet/PROFINET interface.
To prevent data losses, PCs must be shut down in time before the buffer time ends. If the
input voltage returns after the shutdown has already started, the SITOP UPS1600 terminates
the buffer mode and transitions into normal operation. PC shutdown is completed to the end
and the internal power supply is brought into the standby state. PCs, which do not have an
on/off switch, can only be rebooted by switching off the power and switching on again.
When the "Interrupt output voltage" jumper is inserted, the UPS generates this pulse.
Start from the battery (pin 14)
The start from the battery is initiated by connecting pin 14 to pin 10. This jumper must not
provide a permanent connection, but must be controlled using a button. The input is
designed so that a single lamp with a permissible supply voltage of between 12 and 30 V and
8 to 15 mA can be switched in series to the switching contact. If the button is actuated when
the input voltage is not available, and if buffering is permitted, then the UPS goes into the
buffer mode. The SITOP UPS1600 shuts down if, at the end of the selected buffer time, an
input voltage is still not available.
The SITOP UPS1600 starts in normal operation if the input voltage is available.
