Wiring example (overview)
Switching the power supply on/off
The UPS ensures that the XC600 controller is switched off properly
in the event of a power supply failure. This requires the inputs/
outputs of the UPS device and the other devices to be wired as
shown below.
in the event of a power supply failure. This requires the inputs/
outputs of the UPS device and the other devices to be wired as
shown below.
If the supply voltage to the UPS device drops, the controller is
supplied with the battery supply voltage. The contact ”C1” in the
UPS device opens and the circuit at the Power Fail input of the
power supply module is interrupted. This will cause the controller
to initiate the PFI signal, which will cause the system to shut down.
The controller requires approximately two minutes to do this.
supplied with the battery supply voltage. The contact ”C1” in the
UPS device opens and the circuit at the Power Fail input of the
power supply module is interrupted. This will cause the controller
to initiate the PFI signal, which will cause the system to shut down.
The controller requires approximately two minutes to do this.
By connecting the Battery off input of the UPS to contact C2, the
UPS device can switch off the battery supply voltage after two
minutes. The battery is then used only for these two minutes so
that further battery backup protection is ensured occur. If power
is restored after two minutes, the controller will start up again
according to how the operating mode selector switch is set.

is restored after two minutes, the controller will start up again
according to how the operating mode selector switch is set.
A different routine is followed if the power supply to the UPS
returns within two minutes: while the power to the UPS device has
failed, the controller is at first initially supplied by the battery
voltage until power is restored. As the UPS device signals the
power failure to the controller (Power Fail input), the controller
starts a system shutdown (2 minutes). The following message will
be shown on the display: ”PFI shut down in progress”.The opera-
tion ends with the message ”TURN OFF YOUR CONTROLLER” on
the display.

In this case, the controller has not detected a power failure. When
the PLC is restarted, the power supply of the UPS system must be
switched off and on again. If the start is to take place automati-
cally, an on-delayed timer must be used to lengthen the interrup-
tion to more than 2.5 minutes (a Fig. 10).
