Installation3.4.3. Point Detector Rod Adjustment With Lock Rod ReleasedTable 3–7. Point Detector Rod Adjustment ProcedureWith Lock Rod Released (Lock Rod “Floated”)StepAction1 Release lock rod. A switch machine can have either a narrow-notched orwide-notched lock rod in this procedure.2 Crank open switch point associated with long point-detector rod.3 Place 1/4-inch obstruction gauge in switch point. Place lock rod so machinecan lock.4 Crank switch to close switch point and lock switch.5 Adjust long-point-detector rod until point-detector contacts just break (open).Tighten rod nuts and verify contacts are still open.6 Crank switch point open and remove 1/4-inch obstruction gauge.7 Crank switch points closed and confirm point-detector contacts have made(closed). This completes long point-detector rod adjustment.8 Adjust short point-detector rod as follows:a. Crank open switch point associated with short point-detector rod.b. Place 1/4-inch obstruction gauge in switch point. Place lock rod somachine can lock.c. Crank switch machine to close switch points obstruction in point.d. Adjust short point-detector rod until point-detector contacts just break(open).e. Crank switch points open and remove 1/4-inch obstruction gauge.f. Crank switch points closed and confirm point-detector contacts have made(closed). This completes short point-detector rod adjustment.P1293, Rev. Jun/07 3–17 Alstom Signaling Inc.
