OM3223 Operation - Section 32 Operator Cab and Controls Page 32-23 The medium overhead indicator light, when on, indicates the operator has selected the sec- ond detent position of the master control lever, forward of the OFF position. In this position, depend- ing on the overhead line voltage, the truck speed may vary from 14.3 to 18.0 kph (8.9 to 11.2 mph) while on trolley. See trolley speed chart for speed ranges with different line voltages. C8. Med Speed (Green) E8. Right Limit (Amber) Optional When on trolley, this light will turn on if the overhead power cables make contact too far to the right of the pantograph. To cause the light to go off, the operator must steer to the right.
There are sensors on the panto- graph about one foot from the outer edge of the car- bon collector bar on the pantograph. These sensors warn the operator that he is about to drive out from under the overhead cables while on trolley. D8. Low Speed (Green) The speed indicator lamps indicate the speed level selected by the master control lever position for truck operation. If the slowest speed is selected, only low speed indicator lamp comes on. At the highest level, all speed level lamps are on. The low overhead indicator light, when on, indicates the operator has selected the first detent posi- tion of the master control lever, forward of the OFF position.
The LOW position will cause the truck to move at it's slowest speed while on trolley. In this position, depending on the overhead line voltage, the truck speed may vary from 12.2 to 16.0 kph (7.6 to 10.0 mph). See trolley speed chart for speed ranges with different line voltages. .
