Ammann ARR 1575 - Error Indications and Safety Bar Logic

WORKSHOP MANUAL
6.1.2 Error indication via LEDs on the display unit
Error indication (inclination switch)
Indication Reason Corrective action
Error lights up The inclination switch activated. The roller is inclined by more than approx. 45° or
overturned.
Set the machine upright.
If the roller overturns, the ignition deactivates for safety reasons.
The machine control is equipped with an inclination sensor. This sensor activates when the inclination angle exceeds
45°. The engine then
automatically turns o. After the sensor activates, the machine cannot be started.
If the machine is overturned, engine oil cannot reach the combustion chamber. Starting the engine after the machine is
set upright again may cause engine damage.
Set the machine upright. Do not start the engine.
Contact aservice workshop.
Error and Safety Bar indication
Indication Reason Corrective action
Error lights up The switching transistor signals astatus error. This means,
for example, that ashort circuit or broken cable has been
detected.
Check that the cable is not
short-circuited or broken.
The Error and Safety Bar indicator lamps
are on simultaneously
The control unit of the machine waits until the “Oil Pres-
sure” and “Alternator” inputs are in the basic position.
Check the Oil Pressure and
Alternator outputs.
Pay attention to the indicator lamp priority: First the inclination switch, then “waiting” and nally the status error
transistor.
Safety Bar indication
Indication Reason Corrective action
The Safety Bar indicator lamp is on The safety bar switch activated. Put the safety bar to the initial position.
The Safety Bar indicator lamp is ashing Near halt detected. Move at least 2.5 m away from the roller.
The Safety Bar indicator lamp is illumi-
nated brightly
Near eld detected. If the roller is controlled using acable, the user must
be located in the so-called near eld (at adistance of
2.5 to 4 m).
CAUTION!
Pay attention to the indicator lamp priority: First the safety bar switch, then near halt and nally near eld.
