Marker Interface Enclosure
(SC 370d - L-864/865 only)
Operation Overview
The Marker Interface Enclosure mounting
diagram is shown in Figure 2-14 (Stainless
Steel option shown in Figure 2-15) and
the wiring diagram is shown in Figure 2-
32.
Operational power for the Marker
Interface PCB and connected L-810
markers is supplied by the flashhead cable.
TB1, located in the marker interface
enclosure, provides a splice point for the
flashhead cable which then continues to its
termination point at the flashhead. Marker
connections are provided at terminals J1 –
J4 located on the Marker Interface PCB.
Marker programming, control and status
are accessed through the User Interface
located on PCB 1 of the SC 370d. Power
Line Communication over the flashhead
cable is utilized as the communications
link between the SC 370d and the Marker
Interface PCB.
LEDs located on the
Marker Interface PCB provide operational
status during service.
