Safety information

3.1

3.2 General working safety

●

The roller may only be used for driving on and compacting loose top layers (gravel, earth). Other uses are prohibited.

Rollers may only be operated with all safety devices operating. Manipulation or disregard of safety devices and regulations invalidates the CE conformity.

Before starting every shift, check the effectiveness of the operation and safety devices and that the protection devices are in place.

Check the steering and brakes when you start work. If defects are apparent, roller operation is not permitted.

If you identify any defects on the safety system or defects that impair safe operation of the equipment, inform your supervisor immediately. The roller may no longer be operated.

If you identify any defects which endanger safe operation, cease operation immediately.

Only perform work on and clean the roller if it is stationary and secured from rolling away.

Switch off the engine when filling the fuel tank. Do not fill up fuel in enclosed spaces. No open flames.

Do not vibrate on slopes or inclines where there is a hazard of slipping or overturning.

Do not drive on slopes that are steeper than the maximum climbing capacity of the equipment. Always drive the roller carefully perpendicular to the slope dip.

Do not vibrate inside buildings and on unstable ground.

The driving and working field of view must not be obstructed in any way.

Switch off the engine before leaving the roller. Secure the roller against unauthorized start-up and rolling away.

Take suitable visible measures to secure parked rollers that pose an obstruction.

Never work under the influence of drugs, alcohol or medicines that impair consciousness.

Only operate the roller in good general light conditions and good workspace illumination.

The workplace of the operator is located at a safe distance of at least 2m.

Roller operation

DANGER

Rollover hazard when driving the roller!

• Only start the roller using the handheld transmitter.

• Personnel may not stand in front of or behind the roller while it is in operation.

• Persons necessary for operations at the sides of the equipment must remain at a safe distance of at least 2 m.

3.2.1 Shear points

●

When closing the hood ensure that no objects are situated between the hood and the chassis.

Take care that nothing is jammed in the joint plates when rotating the roller drums.

Do not put hands between the roller drum and support during operation.

24 Rammax 1575

DANGER

Danger to life through tipping or slipping of the roller! The edges of filled areas may give way!

• Only travel directly up or down slopes.

• Do not drive across slopes.

• Keep your distance to embankments and edges!

• Do not drive at an angle into or out of the trench.

• Park the roller on slopes only in such a way that it cannot overturn.

• Use the roller on slopes only in such a way that it cannot overturn.

• The roller drums have very poor adhesion on snow and ice.

Driving or working on a slope in snow or ice is prohibited.

• Damp and loose surfaces reduce the traction of the machine on upward and downward grades considerably. Adapt the speed of the machine to the terrain when driving on grades.

• The nature of the ground and weather conditions can negatively affect the climbing ability of the machine.

Never drive on slopes that are steeper than the maximum climbing ability of the machine.

Fig. 3-1 Tipping hazard

Construction site conditions can have a negative effect on stability and the tipping angle.

DANGER

Crushing hazard in the area of the articulated joint

• During operation, there is always a crushing hazard in the area of the articulated joint. Therefore, it is not permitted for persons to be in this area during operation. In general, a safety distance of at least 2 meters to the machine must be maintained during operation.

DANGER

Crushing of toes through careless handling of the roller!

• Wear safety shoes when working with the roller in order to help avoid crushed toes.

LED error display on the display unit

Tab. 5-1 Error display (tilt switch)

Display

Error lights up

Cause

The tilt switch has been triggered. The roller is at an angle of more than about 45° or has tipped over.

Remedy

Set the machine upright.

For safety reasons, as soon as the roller tips over, the ignition is also shut off.

The machine controller is equipped with an inclination sensor. It triggers as of an angle of 45°. In this case, the engine shuts itself off automatically. The machine cannot be started as long as the inclination sensor remains triggered.

If the machine has tipped over, it is possible for engine oil to enter the combustion area. If the machine is started after it has been righted, engine damage is possible.

• Set the machine upright. Do not start the engine under any circumstances.

• Inform the service Service.

Tab. 5-2 Error and shutdown bar display

Display

Error lights up

Error and shutdown bar light up in unison

Cause

A switching transistor signals a status error. This means that, for example, a short circuit or a cable break has been detected.

The machine controller is waiting for both the inputs “Oil pressure” and

“Alternator” to be at the rest position.

Remedy

Check the cable for a short circuit or cable break.

Check the oil pressure and

Alternator outputs.

The roller is being controlled via infrared.

Battery charge monitoring

The red LED blinks either faster or slower depending on the battery charge level. The lower the charge state, the longer the on-phase of the LED.

Tab. 5-5 Battery charge monitoring display while performing a function

Display

The red LED flashes briefly

The red LED always lights when a control is operated.

The red LED flashes.

The red LED is lit.

Cause

The battery is slowly becoming drained

When the battery is drained, it is no longer sent.

The battery is being charged.

The battery is fully charged.

Remedy

Connect the charging cable for at least 1h.

It is still possible to control via the cable once the battery is empty.

Battery warnings and errors are only displayed during active control (i.e., when a control element is actuated).

As soon as and as long as the infrared transmitter is attached to the machine controller via the cable and the ignition is turned to I, the red LED must flash or be lighted.

NOTE

Tab. 5-6 Automatic pairing display

Display

The green and red LEDs are blinking in unison quickly.

Cause

The infrared transmitter is coupled with the machine controller.

This procedure normally only takes a maximum of about 3 seconds. If this blinking lasts longer or should even become permanent, there is a problem with pairing:

• A cable break in one of the signal lines

• A short circuit in one of the signal lines

As long as this blinking pattern remains, no control signals will be sent to the machine controller. Engine does not start.

Infrared transmitter

Operating and display elements 41

Automatic pairing occurs at the moment the cable is unplugged, or, if the cable is plugged in, when the ignition is switched on.

Special cases

●

When the infrared transmitter is switched on, both LEDs are switched on briefly. This feature helps to determine that the LEDs are still functioning.

As soon as the cable is unplugged from the handheld transmitter or from the roller, the red LED lights up for about 1 second.

NOTE

Introduction

This section describes possible causes and action sorted according to error symptoms.

Note that the machine wiring, although not mentioned explicitly, is always a possible cause of electrical problems.

In our experience, in most cases errors are caused by the wiring harness or connectors.

Therefore, it is a good idea to check the machine for frayed cables and defective or loose connectors first.

Since the machine is remote-controlled, faults can be due to a variety of causes. The best thing to do is to read through this chapter quickly at first in order to get a general overview.

Also make sure to pay attention to the LEDs on the handheld controller and the lamps on the display unit.

The machine will not shut down automatically when the hydraulic oil temperature is too high!

If you think the machine may be getting too hot, check:

• Fuse F14

• Oil temperature switch S25

• Relay K7

• Radiator M3

Oil temperature switch S25 should turn on the fan if the oil temperature is 50°C or higher.

8.3.3 The controller is not working

Follow the instructions below step by step in order to pinpoint faults and fix them.

External factors

●

Reflective surfaces (mirrors, reflective strips, etc.) in the machine’s close vicinity can interfere with the remote controller’s distance calculating function.

Special sources of light (fluorescent tubes, flash lamps, etc.) may interfere with infrared communications under certain circumstances.

Strong electromagnetic radiation (e.g., in the proximity of power plants) may affect the controller.

If faults occur only at specific locations or in specific situations, check the machine’s surroundings to see if any of the above factors are present and try to avoid them.

Machine wiring

●

Are fuses F11 and F12 OK?

Are the connectors on controller N1 free of soiling and water?

Is controller N1 properly mounted?

Are both the P1 and P2 infrared sensors clean and free of damage?

Is the wiring from N1 to P1 and P2 free of damage? Keep in mind that there is an X5 adapter (going towards the front sensor) in the engine compartment.

Is the cable to handheld controller N3, together with the corresponding connectors, free of damage and of soiling? Do not forget connector X1 on the hood’s inside.

Operation

●

Is the handheld controller already paired with the machine? -> Briefly connect the handheld controller to the cable for this purpose.

Is the distance between the handheld controller and the machine OK? (2.5m - 4m in cable mode or 2.5m - 20m in remote control mode)

Is the battery for handheld controller N3 empty? -> Use the cable mode temporarily fir control.

Check the machine as instructed in the previous description.

If none of the LEDs on handheld controller N3 flash even during cable operation, the unit may have to be replaced.

Check the wiring.

Check the machine as instructed in the previous description.

If the red LED on handheld controller N3 always flashes when a function is carried out during wireless operation, or if none of the LEDs light up during wireless operation, the battery is probably faulty.

Also check the display unit. The tilt sensor may have been incorrectly triggered.

The switch must be open when the operating temperature is normal.

The switch must be open when the engine is running.

Connection D+ must have a voltage of 12 V when the engine is running.
