are plugged in.

Primary fuse blown (located at the

mains inlet cable).

(F601 and F602) and replace.

Fixtures reset correctly but all

respond erratically or not at all to

the controller.

The controller is disconnected from

the data link.

Connect controller.

XLR pin-out of the controller does

not match pin-out of the first fixture

on the link (i.e. signal is reversed).

Install a phase-reversing cable between the

controller and the first fixture on the link.
