OM3241 Operation - Section 32 Operator Cab and Controls Page 32-23 Trolley Fault Indicator The trolley fault indicator (D7) lights when a trolley fault occurs while the master control switch is in the TROLLEY position. The indicator is red. Return the mas- ter control switch to the DIESEL position for a minimum of 1 second to reset the fault. Max Speed Indicator The max speed indicator (A8) lights when the operator has selected the fourth, and last, detent position of the master control lever. When the lever is in this detent position, the truck will be able to reach it's maximum trolley speed. Depend- ing on the overhead line voltage, the truck speed may vary from 12.7 to 14.7 mph.
Refer to the trolley speed table in Section 30, Operating Instructions, for speed ranges with different line voltages. The max speed indicator is green. NOTE: STATEX III records the number of "faults/ events". When a predetermined number of "faults/ events" are recorded within a given time frame, the operator will not be able to reset the fault/event by using the override switch. If this occurs, notify maintenance personnel immediately. NOTE: The speed indicator lamps indicate the speed level of the master control lever position. If the slowest speed is selected, only the low speed indicator lamp will light. In maximum spped, all speed level lamps will light.
If a trolley fault occurs while operating in the diesel mode, switch the master control switch to the TROL- LEY position for a minimum of 1 second, and then back to the DIESEL position, to reset the fault. The trolley fault light can indicate the type of problem that is associated with the fault. High Speed Indicator If the indicator is flashing, an excessive payload caused the fault. The high speed indicator (B8) lights when the operator has selected the third detent position of the master control lever. In this position, depending on the over- head line voltage, the truck speed may vary from 11.0 to 13.1 mph while on trol- ley.
Refer to the trolley speed table in Section 30, Operating Instructions, for speed ranges with differ- ent line voltages. The max speed indicator is green. If the indicator is continually lit, a problem exists with the truck’s trolley system. Left Limit Indicator (Optional) When on trolley, the left limit indi- cator (E7) will light if the over- head power cables make contact too far to the left of the panto- graph. The indicator is amber. To turn the indicator off, the opera- tor must steer to the left. There are sensors near the outer edge of the carbon collector bar on the panto- graph. These sensors warn the operator that truck alignment is necessary. NOTE:
The speed indicator lamps indicate the speed level of the master control lever position. If the slowest speed is selected, only the low speed indicator lamp will light. In maximum spped, all speed level lamps will light.
