Section 8. Theory of Operation Lift/Lower
24" Limit Switch (S6) The 24" limit switch is mounted to the carriage, and the switch rail is mounted on the lift truck frame 24" (60.96 mm) from the bottom. The switch is closed until the carriage lifts high enough for the switch to run above the switch rail. When open, the switch limits travel speed to 3 mph (4.8 km/h). Travel speed is further limited to 1 mph (1.6 km/h) when steering is more than 10° from center. If the lift truck is equipped with the High Performance option, travel speed is limited to 2.5 mph (4 km/h) when this switch is open and the steering angle is greater than 10° from center. There is no speed limit if the steering angle is less than 10°.
150" Limit Switch (S29) The 150" limit switch is mounted to the mast behind the battery connector. This switch opens when the outer telescopic raises above it and the forks are 150" off the floor. At this height, travel speed is limited to 1 mph (1.6 km/h), or disabled if the steering angle is more than 10° from center.
60" Limit Switch (S7) (Optional) The 60" limit switch is included with the High Performance option. This switch is mounted on the carriage and limits travel speed to 4.3 mph (6.9 km/h) when open, or 1 mph (1.6 km/h) if the steering angle is more than 10° from center.
120" Limit Switch (S29) (Optional) The 120" limit switch is included with the High Performance option. This switch is mounted on the mast and limits travel speed to 2.5 mph (4 km/h) when open, or limits travel speed to 1 mph (1.6 km/h) if the steering angle is more than 10° from center.
180" Limit Switch (S25) (Optional) The 180" limit switch is included with the High Performance option. This switch is mounted on the carriage and limits travel speed to 1 mph (1.6 km/h) when open, or disables travel if the steering angle is more than 10° from center.
Lift Limit Switch (S24) (Optional) The lift limit switch disables lift when open. This switch is mounted on the mast. It can be bypassed by pressing the lift/lower limit bypass switch on the carriage.
Lift/Lower Limit Bypass Switch (S51) (Optional) When the lift limit switch (S24) is open, pressing the lift/lower limit bypass switch allows the lift truck to continue lifting.
Lower Limit Switch (S60) (Optional) The lower limit switch disables lower when closed. It is mounted on the carriage and can be bypassed using the optional lift/lower limit bypass switch (S51) on the carriage.
Pump Contactor The pump contactor provides power to the lift motor and is closed during lift.
Load-Holding Solenoid The load-holding solenoid is closed whenever there is no request to lower. When lower is requested, the solenoid opens. It closes when lower is no longer requested.
