15 ST OP LIGHTS/CAB TIL TING G EAR ST OP LIGHTS When the b rake pedal is pressed, the s top light control s witch E 51 1 is a ctivated (connection between contacts 2 - 1 ) and the relay (G036) will be energised. There is a lso a voltage on F628. Through fuse E013, wire 1209, contacts 30 and 87 of relay G 036 and wire 4601 a v oltage is now applied to the right stop light (C021) and the left s top light (C020), so that they go on. The lights that are connected v ia the trailer p lug s ocket A 000 will also go on. When relay G 036 is energised, the c onnection 30 - 78a is broken. The v oltage on D814 (UPEC electronic unit) or D903 (ECS-DC3 electronic unit) is lost. CAB TIL T ING G EAR There is a v oltage on sensor F676 (cab locking sensor) and on sensor F616 (cab tilting cylinder sensor) through fuse E018 and wire 1 1 14. There is a lso a v oltage on connection point 2 o f s ensor F676 through connection points 1-2o fr e la y G 3 5 1 (c a b ti lt protection microrelay) and wire 4723. When this sensor is activated, the v oltage is transmitted to c onnection point 16 of D900 (VIC) and to connection point 2 o f s ensor F616. The V IC now sends a m essage to the DIP that then activates the “cab tilted ” warning light. W hen sensor F616 is activated, relay G351 is energised and, as a result, a v oltage is applied to B251 through contacts 3 and 5 and wire 4722 (neutral position buzzer , tilting cab). If the contacts in switch E569 (neutral position s witch) are closed (connection between pins 4 - 2 ), the horn w ill go of f.
