Product Description
5.5.1 Function selector switch (only with VBA-2E-KE4-ENC-S)
Mode for factory settings
The function selection switch S1 can be used to reset the device to its default set-
tings.
Disconnect AS-i voltage.
Set the function selection switch S1 to the On position (Clear).
Finally connect AS-i voltage again.
A run light on LEDs ST1, ST2, F1 and F2 appears for 5 s.
During this time push and hold the projecting button as long as the running
light stops flashing.
The device is reset to its factory default settings.
Set the function selection switch S1 to the Off position (Run).
The device is in the normal operating state.
5.5.2 Projecting button
VBA-2E-KE4-ENC-S
The Projecting button can be used to store currently present frequencies. The
stored values can then be loaded via software.
While values are being stored the CONF LED flashes.
The CONF LED goes out again as soon as the stored values have been loaded.
Values stored using the Projecting button are deleted at Power-on.

VBA-2E2A-KE4-ENC/SSI-S
By short pushing the Projecting button, the global reset of error condition can be
triggered, in order to reset red-flashing configuration devices or an output that has
shut down because of an overload.
• If no error is present, currently available frequencies and/or positions can be
stored temporary for processing. These values can then be uploaded via soft-
ware.
• The Projecting button can be used to reset the device to its default settings:
Mode for factory settings (VBA-2E2A-KE4-ENC/SSI-S)
Disconnect AS-i voltage.
Push and hold the Projecting button.
Holding the button, connect the AS-i voltage again.
A running light on LEDs ST1, ST2, F1 and F2 appears for 5 seconds.
After the running light is started, release the button and confirm the process
with short pushing the button.
The device is set to the factory settings.
The device is in configuration mode.

Product Description
5.5.3 Chip card
The chip card is used for storing the device parameters, speeding up the time re-
quired to replace defective units. Exchanging the chip card moves all parameters
from the old unit to the new one.
Unit replacement: Chip card "not blank" in a non-configured unit (unit in
factory default state)
If a non-blank chip card is plugged into a configured unit, the data are copied to
the unit.
Blank chip card in a configured unit
If a blank chip card is plugged into a configured unit, the data are copied to the
chip card.
Data in the unit and the chip card are not the same
If the chip card and the unit are not blank and contain different data, there will be
an error message (see Sec. <LEDs>).
5.5.4 Sensors
To VBA-2E-KE4-ENC-S only rotary and linear encoders may be connected.
To VBA-2E2A-KE4-ENC/SSI-S also angle or position encoder can be connected
next to rotary or linear encoders.
Warning!
Verify the safety functions after replacing the unit!
Information!
Please note additional information in Sec. <Safety Requirements>.
