PROBLEM SOLUTION
Why is the unit not operating as it should? Make sure the power cord is plugged in and the power switch is turned on. If the unit
still fails to operate, remove the front panel and press the reset button. Make sure the
DIP switch settings are correct. Check the input power fuse. You may need to replace
it. Refer to Figure 14.
What is the DB9 port used for? This port is used for diagnostics. A technical support representative may ask you to
enable this feature should a problem arise with the unit. This port is not needed for the
every-day operation of the ALM2064.
