Conveyor control switches (1) (left) and (7) (right)
Conveyor indicators (2) (left) and (6) (right)
Optional conveyor boost switches (3) (left) and (5) (right)Conveyor neutral indicator (4) and an upper stage conveyor speed potentiometer (8) are located only on the right side of the instrument panel.Conveyor Control Switches
Conveyor control switches (1) (left) and (7) (right) are toggle switches with three positions. The bottom position of these switches is the OFF position. The center position is the HOLD position. The top position is the ON position. These switches are spring returned to the HOLD position.Circuit breaker "CB1" distributes power to contact "2" of left conveyor control switch (1), to contact "5" of the left conveyor control switch, and to contact "5" of right conveyor control switch (7). When the left conveyor control switch is in the HOLD position or when the left conveyor control switch is in the ON position, contact "1" of the left conveyor control switch transfers power to contact "2" of the right conveyor control switch.Conveyor Indicators
Conveyor indicators (2) (left) and (6) (right) illuminate when the key switch is in the ON position and one of conveyor control switches (1) (left) and (7) (right) is moved to the ON position. The indicators receive power from contact "4" of the conveyor control switch when the switch is held in the ON position. After the switch is released, contact "87" of the conveyor control relay provides the power in order to illuminate the indicators.Note: Conveyor indicators (2) (left) and (6) (right) can be illuminated while the engine is not operating. If the conveyor control circuit has been activated while the engine is not operating, the engine cannot be started.Conveyor Boost Switches
Conveyor boost switches (3) (left) and (5) (right) are momentary type, push button switches. When one of the conveyor boost switches is actuated while the conveyor is operating, the speed of the upper conveyor increases. The upper conveyor remains at the higher speed until the conveyor boost switch is released. The right and left switches are wired in parallel. If either switch is depressed, the conveyor speed increases.Contact "2" of conveyor boost switches (3) (left) and (5) (right) receive power from contact "4" of conveyor control switch (1) (left) and (7) (right) when the conveyor control switch is held in the ON position. After the conveyor control switch is released, contact "87" of the conveyor control relay provides the power to contact "2" of the conveyor boost switches.Conveyor Neutral Indicator
Conveyor neutral indicator (4) alerts the operator that the conveyor controls are activated and the key start switch is in the START position. The conveyor neutral relay controls the conveyor neutral indicator. When the conveyor neutral relay is energized, the conveyor
