Marker Alarm Setting
The Marker Alarm Setting switch sets the number of marker lamps at which a marker
alarm will be generated. The switch is adjustable from zero to four lamps. The factory
default setting is one, meaning that a marker alarm will be generated when one or less
marker lamps are burning.
Manual Mode Select Switch
The Manual Mode Select Switch overrides the photoelectric cell (PEC) to allow selection
of Day mode or Night Mode for test or troubleshooting purposes. The Day or Night Mode
lights flash when in manual mode. This switch should be left in the AUTO position for
normal operation. In the AUTO position the operating mode is determined by the
photoelectric cell.
