Connecting an AMX PC-1 AC power controller to the MLC for lighting control

The AMX PC-1 relay box can be configured for momentary or latching operation. All front panel DIP switches should be in the down position for latching mode operation. See AMX’s instructions if you need to change modes. Also set the MLC’s relay to “latching” and “normally open”.
