Troubleshooting Guide

•

Check for incoming power at MK1 connector.

•

Check fuse at F1 (Fig. 6).

•

Check for input power at the base of the power supply.

•

Check for 5vdc between MH5 and MH6 on the 255PROGBD (the yellow 5v in

LED and the green 5v out should be lit.

•

Contact Danfoss Technical Support to resolve source and resolution of your

particular error messages.

•

Insure that the battery jumper at JP5 on the base board (Fig. 7) is set on the

right two pins (this is the enabled position).

•

Check to see that there is a valid database with history configured.

•

Check to see that history status is Collecting and not Suspended

•

See if you can access history retrieval via the keypad via the AKA65

•

If you can still not access history contact Danfoss Technical Support for further

options.

•

Insure that the battery jumper at JP5 on the base board (see Fig. 7) is set on

the right two pins (this is the enabled position).

•

Now try resetting the correct date and time. Observe this new time for several

minutes.

•

If, after several minutes, the clock appears to be correct you have most likely

corrected the perceived problem.

•

If, after a short time, the date returns to 01/31/95 and the clock to 00:00:00...

call Danfoss Technical Support for further assistance.

•

The most common EDF message is one saying "Could not Load..., " this usually

implies that the necessary EDF was not in the correct directory or folder. Make

sure the EDF mentioned in the error message is in your list of EDF's.

•

Remember, after loading EDF's or a Device List you must reset the AK-SC255.

•

If your problem is still not resolved, call Danfoss Technical Support for

assistance..
