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”.
