Switch off sensor/
tachogenerator
For values measured twice, you can switch off the faulty sensor/tachogen-
erator in the case of an error and continue working with one sensor/tacho-
generator for a short time.
•
Call up the error (
1
) for the faulty sensor/tachogenerator in the
Errors
sub-
menu, e.g.
1.02.1
for pressure sensor 2.
•
Press button
P
once.
The faulty sensor/tachogenerator is switched off and the corresponding
error (
1
) is displayed, e.g.
1.02.8
for pressure sensor 2.
When the ignition is switched on again, the shutdown is cancelled and the
error occurs again, possibly with a different last digit, e.g. 1.02.5.
After switching off the faulty sensor/tachogenerator, you should check
whether the other sensor/tachogenerator is functioning correctly.
Checking the pressure sensor function
•
Lift the hook block without a load.
•
Check whether the display (
1
) indicates the approximate weight of the
hook block.
Checking the angle sensor function
•
Set down the main boom on the boom rest.
•
Check whether the display (
1
) shows an angle of 0°.
G
Danger due to RCL failure
Have the error resolved before the next crane job.
This allows the crane to still be unrigged without RCL monitoring if the sec-
ond sensor/tachogenerator fails.
G
Risk of accident from faulty functioning
After switching off the faulty sensor/tachogenerator, begin crane operation
only if the display of the remaining sensor/tachogenerator is correct.
This prevents the RCL from not switching off when leaving the working
range and the truck crane overturning as a result.
