120Service Manual – SC6000 38 - Squeegee SystemActuator Limit AdjustmentThe power module commands the actuator to raiseor lower, but the actuator itself determines whenit should stop moving This is accomplished by twocam lobes and two micro switches (limit switches)The lower cam is not adjustable, so the lower limitis adjusted by rotating the leadscrew nut Then theupper limit is adjusted by turning the cam lobe untilthe actuator stops at the correct heightTo make the adjustment, you will need to manuallypower/control the actuator If you don’t have theActuator Test Kit described on page 125, you canuse the Squeegee Lift Output Test described on page33 Just note that if you use the Output Test, youmay periodically cause a controller fault, and have toreset the machine For simplicity, this procedure iswritten for the test kit methodThis procedure is typically performed as part ofreplacing the actuator If the actuator is not already removed from the machine, then remove it following theprocedure on page 1241 Connect the tester (A) to the positive and negative terminals of the battery2 Using the adapter cable (B), connect the tester to the actuator3 While preventing the actuator leadnut (E) from turning, use the switch (C), extend the actuator until itstops4 Measure the distance between the actuatorgearbox at (G) and the top of the leadnut at(F)5 Manually turn the leadnut until thisdistance is 68mm (2.7”).CAUTION: If while retracting the actuatorwith the “Output Test”, itappears the leadnut is goingto crash into the actuatorhousing, let go of the leadnutand let it spin.6 While holding the leadnut from turning,retract the actuator until it stops7 Measure the retracted distance between (G&F). The target is 23mm (.93”).CBA68mm Extended23mm RetractedEG F
