INTERNAL WIRING

The following figure details the S-80 Entrance Gate interior wiring.
Siemens recommends the use of a double-break Positive (+) and
Negative (-) Gate Control (GC) circuit.
If single-wire GC is desired, connect positive GC from the wayside to the
GC+ (GC positive) terminal on the control board. In addition, run a jumper
between the GC- (GC negative) terminal and the BATTERY N12 terminal
on the control board.
The maximum wire size for the jumper is #12 AWG, solid or stranded wire.
Gate application design (mechanical and electrical) should be done in
accordance with Part 8 (Traffic Controls for Highway Rail Grade Crossings)
of the MUTCD Manual, latest revision. This includes installation of gate
mechanism foundations to achieve the required gate arm vertical height
above the roadway, and horizontal clearance to the edge of the roadway.
The digital contacts emulate the mechanical contacts supplied on previous
gate mechanisms. They do not supply an output power source to energize
external devices. They are single pole contacts that are used to open and
close series circuits.
The digital contacts are isolated from the gates main Battery source and
Gate Control (GC) circuitry.
