Note: The above illustration shows a left operator station. The right operator station is identical except for the reversed positioning of horn switch (1) and E-stop switch (2) .

Horn switch (1) is a momentary-type, push-button switch. The switch activates the horn on the screed.

E-stop switch (2) is located at the upper corner of the operator station. The E-stop switch disables machine functions and stops the engine when activated.

E-stop switch (2) is a push-pull switch with upper and lower positions. The upper position is the RUN position. The lower position is the STOP position. All the E-stop switches on the machine must be in the RUN position for the machine to operate normally.

When E-stop switch (2) is moved from the RUN position to the STOP position, the E-Stop function is initiated. In this case, the engine is shut down, the conveyor and auger are disabled, the functionality of the screed is disabled, and the park brake is applied.

Extender control pendant switch (4) enables and disables the extender pendant when a pendant is installed. The switch controls the respective pendant for the side of the screed the station is controlling. When the pendant is enabled, extender control pendant indicator (3) is illuminated.

Note: Extender control pendant switch (4) does not disable horn switch (1) and E-stop switch (2) on the pendant. These switches are always active regardless of the pendant switch state.

Mainframe extender control (5) operates the respective mainframe extender for the side of the screed the station is controlling. The mainframe extenders are optional. The left and right direction switches operate the respective mainframe extender in the indicated direction. Therefore, extend and retract functions depend on the operator station position. A left mounted station will extend the mainframe extender to the left while retracting the mainframe extender to the right. A right mounted station will extend to the right while retracting to the left.

Rotary dial (6) is an infinite-rotation encoder. This dial allows setting the parameters of four screed functional modes. Each mode is indicated by LED mode indicator (7). Each mode is selected using mode selector switch (8). The following four modes are available:

• Material height - Upper left indicator

• Tamper speed - Upper right indicator (screed-specific option)

• Vibratory speed - Lower right indicator

• Screed assist pressure - Lower left indicator

Note: The material height indicator is the default mode indicator. After 10 seconds, if no mode is selected and the rotary dial is not used, the material height indicator is illuminated.

Mode indicators (7) cycle in a clockwise direction for each press of mode selector switch (8). The selected mode is adjusted using rotary dial (6). Rotating the dial counter-clockwise decreases the setting. Clockwise rotation of the dial increases the setting.

Note: The tamper system is not installed on this screed. Therefore, the tamper speed indicator does not illuminate and will be skipped during the mode selection cycle.
