Setting Elevator Travel Limits
2.3.1.
The elevator travel limits are determined by the position of the cable stop collars which operate the limit
switch to deenergize the drive motor and to engage the brake. Upper cable stop collar controls the up
travel of elevator. Lower cable stop collar controls the down travel. These collars have been set at the
factory and require no adjustment under normal conditions. Should adjustment become necessary
because of slippage or part replacement, use the following procedure.
2.3.2.
Operate elevator control and raise platform to the maximum height position. If limit switch operates to
prevent raising to this height, loosen allen set screw on upper cable stop collar. Slide collar upward on
cable. Operate elevator control and raise platform to the maximum height position.
2.3.3.
Slide collar on cable downward , until distinct click sound is heard and brake is engaged. The click
indicates that the switch has opened and will stop the motor in that position when operated. Tighten
collar allen screw securely.
2.3.4.
Operate elevator control and lower elevator to a position where the bottom of the platform is about 2"
above the bottom of the tank. To adjust, perform the same adjustment procedure for the lower cable
stop.
2.3.5.
Operate elevator control to raise and lower platform to maximum positions and check for proper
operation. Repeat above adjustment if platform does not stop at designated positions.
