Section 3 OPERATION

7/00 3-23

LIMITED OPERATION MODE [See Figure 3-3].

The "limited operation mode" allows the machine tobe removed from the work surface.

The "limited operation mode" is programed into

computer controller software "Version 2.33" andwas NOT included in previous "versions" of thesoftware.

NOTE:The "version" of the software, containedwithin the computer controller, isdisplayed on the system functionmonitor display screen [ITEM 26] whenthe ignition key switch is first turned tothe "ON/RUN" position.

The machine directional control system will"automatically default" to the limited operation modewhen a "stop fault" condition exists and has beendetected by the computer controller [See Figure 3-3- Screen #1] .

The system function monitor display screen[ITEM 26] will visually "prompt" the operator toreturn either directional/speed control [F-N-R]handle [ITEM 1] to the neutral position.

With the directional/speed control [F-N-R] handle[ITEM 1] in the neutral position, the screen will

display the functions which should allow themachine to be moved.

A message will appear stating "FRNT/FWD"or"REAR/REV"[See Figure 3-3 - Screens #2 and #3] .

The message will inform the operator that bymoving the Drum Vibration Systems "Location"Control Switch [ITEM 9] from the center [BOTHposition] to either the FRONT, or REAR, drumposition machine movement can be achieved.

The machine will travel in FORWARD with theswitch in the FRONT position and in REVERSE withthe switch in the REAR position when either direc-tional/speed control [F-N-R] handle [ITEM 1] ismoved from the NEUTRAL position towards eitherdirection of travel. The Engine Throttle SpeedControl Switch [ITEM 3] MUST be in the "LOW"speed position and the Transmission Range"WORK" [Low] /"TRAVEL" [High] Control Switch[ITEM 7] can be placed in EITHER of the two [2]positions.

DANGER:ALL personnel and other machines MUST be CLEAR of the machine path BEFORE the

machine is moved.

WARNING :The directional/speed control[F-N-R] handle [ITEM 1] does NOTcontrol the direction of machinetravel, during the"limited

operation mode". Thedirectional/speed control[F-N-R] handle is ONLY used tocontrol movement of the machine,but not the speed of themovement. Machine speed is NOTproportional to movement of thedirectional/speed control[F-N-R] handle.

When the directional/speedcontrol [F-N-R] handle is movedfrom the neutral position,regardless of which direction it ismoved, the machine will travel inthe direction which was selectedwith the Drum Vibration Systems"Location" Control Switch[ITEM 9].The machine will travelapproximately 0.75 mph [1.2 kmph]with the Transmission Range

Control Switch in the "LOW"position and 1.5 mph [2.4 kmph]with the Transmission RangeControl Switch in the "High"position.While in the Limited OperationMode, move the machine the LEASTdistance possible, from the worksurface.Do NOT drive the machine to therepair area. Use a truck, or trailer, tomove the machine to the repairarea.

NOTE:Dependant on the "stop fault" conditionwhich exists and has been detected bythe computer controller, limitedoperation may be restricted to eitherforward, or reverse, direction of travel.If travel is not achieved in one direction,attempt to travel in the oppositedirection.
