System Errors

When a system error occurs, the LINK, CONDUCT, and ERROR indicators flash simulta-
neously in a repeating patttern. You can determine the type of error by counting the num-
ber of flashes. There's a two second pause between each series of flashes, as shown in the
following illustration.

Make sure that all power amps are powered up.
Make sure that each power amp is assigned an exclusive amp ID.
Check the RS-485 cable connection between each power amp. If a cable is not
connected properly, or a cable is faulty, power amps further down the line will not
be detected.
Check your Euro-block connector wiring at the ACU16-C and power amps.
This means that the NHB32-C cannot lock to the currently selected wordclock
source. Check and correct the source, or select another.
This indicates that a patch other than the one recalled or stored last is selected.
Recall the patch, or select the patch that was last recalled or stored in order to
stop it flashing.
