Make sure that the correct sensor or switch is tested.Go to Flag 1. Check for +24V on P/J5 pin 1. If the voltage is not present, refer to 11C-120 1KLCSS Power Distribution RAP.Go to the appropriate RAP:• 11-300-120 Docking Interlock RAP• 11-302-120 Top Cover Interlock RAP• 11-303-120 Front Door Interlock RAP11-300-120 Docking Interlock RAPWARNINGTake care not to topple the LCSS.The LCSS is unstable when undocked from the machine.Do not show the customer how to undock the LCSS.Undock the 1K LCSS, refer to REP 11.11-120. Figure 1, check the docking interlock switch,S11-300 as follows:• While supporting the 1K LCSS, slide the 1K LCSS 5cm (2 inches) away from themachine. Check the interlock actuator on the machine is not damaged or missing.NOTE: The wiring harness passes underneath the docking interlock switch housing. Ifthis harness is not correctly positioned, the switch can be mis-located, giving intermittentdocking interlock problems.• Enter dC330, code 11-300, docking interlock switch, S11-300. While supporting the 1KLCSS, slide the 1K LCSS 5cm (2 inches) away from the machine to de-actuate S11-300.If the display does not change, refer to:– GP 13, How to Check a Switch– P/J6, 1K LCSS PWB• Go to Flag 1. Check the wiring between P/J5 and S11-300.• If necessary, install a new docking interlock switch, PL 11.102 Item 2.11-302-120 Top Cover Interlock RAPCheck the top cover interlock switch, S11-302 as follows:• Check the switch actuator.• Enter dC330, code 11-302, top cover interlock switch, S11-302.
