Limit/Home Switch Adjustment

401/402/403XE
Travel limit sensors signal the motor to stop whenever the carriage is approaching the end of travel. The
home sensor provides a fixed reference point to which the carriage can be commanded to return repeatedly.
If equipped, the 401XE, 402XE and 403XE limit switches are set at the factory at the ends of travel and the
home switch is set at the center of travel. To adjust the switches, loosen the screw that secures the switch
into the slot with a flat blade screw driver, slide the switch into the desired position, and retighten.
Printed on the body of the switch is a target (crosshairs). 402XE limit switch settings to utilize full travel are
44mm and 45mm from the target centerline to the end block for the motor and idler locations, respectively.
403XE limit switch settings to utilize full travel are 58mm and 52mm from the target centerline to the end
block for the motor and idler locations, respectively.
