15.5 Arbitrary Display on 7-Segment
After turning on the logic supply (24V), typically a “0”
appears on the display. The green LED of the RJ45
connector lights up green when using active Ethernet
connection.
If there is an arbitrary sign e.g. “8.” or if the display is
flickering, there are the following causes possible:
15.5.1 Defective adapter for logic supply
For the logic supply the adapter should deliver 24V
DC and at least 300mA. Provides the adapter 24V DC
for the logic as well as the power, 5A are required.
Measure logic supply (24VDC), change adapter if
necessary.
15.5.2 Defective Firmware
If a wrong or corrupt firmware data was loaded or
another cause:
Delete XENAX® with DIP switch firmware recorder
and start boot loader:
DIP switch 1 ON
Logic supply ON, firmware recorder is being deleted,
wait until „F“ on display,
logic supply off,
DIP switch 1 OFF
Logic supply ON, display „F“→ boot loader active,
Ethernet connection to PC/Laptop and load new
firmware with WebMotion®.
