fittings at each end. At the lowest point in the air line
insert a T fitting with approximately two feet of Synflex
hanging down to provide a drain for any water than may
get into the system. If a T fitting is not feasible, put a
fitting into the bottom of the display enclosure and route
the 2 feet of Synflex from there.
8. Feed the fiber optic cable through the hose, leaving about
8 inches extra at each end. Cut the fiber ends square with a
sharp knife. Insert the fiber into the connectors at each end
and tighten the connector lock nuts.
9. Mount the rack socket(s) and wire the rack socket(s) to the
controller wires. The controller is wired as though it were a
probe. The wiring pattern for the rack socket(s) should be
verified with the loading rack facility. The wiring code for the
controller is as follows:
COLOR FUNCTION PROBE EQUIVALENT
Red Optic power Optic probe red wire
Yellow Optic pulse input Optic probe yellow wire
Orange Optic pulse output Optic probe orange wire
Black Optic & thermistor ground Optic probe black wire
Thermistor probe white wire
Green Thermistor lead #1 Thermistor probe black wire
Green Thermistor lead #2 Thermistor probe black wire
10. For dual trailer applications, wire the optic portion of the
two controllers in series as though they were probes (reds
and blacks together in parallel, yellow and orange in series).
Wire the thermistor portion with a black probe lead from the
rack socket to a green lead on a controller. The white probe
ground leads from the socket connect to the controller black
ground leads. The green temperature compensation probe
leads from the socket are not connected.
11. Refer to the proper gauge manual and program alarm point 4
as SHUT DOWN at the desired overfill point.
12. Connect a sensor tester to each of the rack sockets and verify
proper rack shutdown by lifting the floats, or simulating float
movement with a programmer.
