Troubleshooting Guide
• Try resetting the AK-SC255
• If that fails to regain control of the keypad contact Danfoss Technical Support
for further assistance.
• Check to see that your Ethernet connection is a valid one.
• Check the plug in connection (lower left most connector, Fig. 8) on the
9AK255CONNBD (connector board).
• Check configuration by going to Communications, Internet and Status to see
that your unit has a valid IP Address.
• If you are just setting this feature up you may need to reset the unit for the
new setting to take effect.
• If none of these things has helped call Danfoss Technical Support for further
assistance
• The Web browser is currently supported only in the "E" and "CS" versions of 255
applications. If you have one of these 2 versions and have concerns about the
correct functioning of your Web Browser contact Danfoss Technical Support
for further assistance.
• Check to make sure the keypad is functioning correctly
• If the database has been lost the default is 12345 Enter, 50 Enter
• If this does not work, call Danfoss Technical Support for assistance.
• The last option is to contact the "chain" head quarters, they are responsible for
maintaining or dispensing Auth codes.
