November 2016 Service and Repair ManualPlatform ControlsPart No. 1272220GT GS-2669 DC • GS-3369 DC • GS-4069 DC 111-1 Circ uit Boar d1-1Circuit BoardHow to Remove the PlatformControls Circuit Board1 Push in the red Emergency Stop button to theoff position at both the ground and platformcontrols.2 Disconnect the platform controls from thecontrol cable at the platform.3 Remove the fasteners securing the platformcontrol box to the platform control bracket.4 Remove the fasteners securing the bottomcover to the platform control box. Open thecontrol box.5 Remove the ties securing the wire harness.6 Disconnect the red and black wires from thealarm.7 Carefully remove the alarm from the platformcontrol box.8 Carefully disconnect all wire harnessconnectors from the platform controls circuitboard.Electrocution/burn hazard.Contact with electrically chargedcircuits could result in death orserious injury. Remove all rings,watches and other jewelry.Component damage hazard.Electrostatic discharge (ESD)can damage printed circuit boardcomponents. Maintain firmcontact with a metal part of themachine that is grounded at alltimes when handling printedcircuit boards OR use agrounded wrist strap.9 Carefully remove the platform controls circuitboard fasteners.10 Carefully remove the platform controls circuitboard from the platform control box.11 Remove the transparent caps from theplatform controls circuit board and save.Circuit board fastener torque specificationsHand tighten until screw seats < 5 in-lbs< 0.6 NmNote: Before installing a circuit board, place thetransparent caps removed in step 11, over thecircuit board buttons.Note: After installing the circuit board, check forproper button operation. Excessive torque of thecircuit board fasteners will cause the buttons tobind. Moderate torque of the circuit board fastenerswill not allow the buttons to engage.
