C8. Med Speed (Green)
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.
D8. Low Speed (Green)
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.
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.
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.
