Connections,
connector X2
If supervision of the supply voltage is required, a bridge connection can be made to an
optional digital input. The supervision instruction must be written in the RAPID program.
This is described in the User’s Guide.
The table below show the connections to connector X2:

The table below show the connections to connector X3:
The input current is 5.5 mA (at 24V) on the digital inputs. A capacitor connected to ground,
to prevent disturbances, causes a short rush of current when setting the input.
When connecting outputs, sensitive to pre-oscillation current, a series resistor (100 W) may
be used.
