Machine functions are activatedusing push buttons on the exterior of the box.Beginning with the 2000 model year (from serialnumber T3400-001 to date), the ground control boxwas changed to a two-board configuration. Thepush buttons used to activate machine functionson earlier models were replaced with a membraneoverlay decal, mounted on the exterior of the box.Programming for all configurations of the the 1998and 1999 model years (from serial numberT3498-001 to T3499-769) is contained in theEPROM, which is installed into the CPU circuitboard.Beginning with the 2000 model year, the machinecan be configured by changing the combination oftoggles of the DIP switch mounted on the CPUcircuit board.The following procedures will notapply for machines manufacturedin the 1998 and 1999 model years.How to Determinethe DIP Switch ConfigurationA diagnostic display wasincorporated into the groundcontrols after serial numberT3402-115. The followingprocedure will not apply tomachines before serial numberT3402-116.1 Turn the key switch to platform control and pullout the red Emergency Stop button to the onposition at both the ground and platformcontrols.2 Press and hold both the secondary down buttonand the turntable rotate counterclockwisebutton at the ground controls.Result: The DIP switch settings will appear inthe diagnostic display.The display will show each toggleof the DIP switch in numericalorder from 1 through 16, andwhether the toggle is in the onposition (01) or off position (00).For example, 0401 shown in thediagnostic display indicates thatthe fourth toggle is in the onposition.baa secondary downb turntable rotate counterclockwise800-610-4101ActionRental.com
