6.19 Overload detection
Application
Trailers with air suspension, e.g. with tipper body or silo
Purpose
Monitoring the load status during loading.
Function
The load status of the trailer is determined by means of sensing the support bel-
lows.
A lamp located on the outside of the vehicle signals the load status, to the driver of
a forklift loading the trailer for example.
The lamp flashes with increasing frequency as the load increases. Longer phases
of being lit are briefly interrupted each time.
When the permissible weight has been reached, the lamp is permanently lit.
In the event of overloading and the load increasing still further, the lamp flashes
again with increasing frequency. However, now longer pauses are interrupted by
brief flashes.
The lamp goes out with the start of driving and only comes on again with renewed
loading.
The function can be deactivated by means of a switch.
The warning lamp is connected to a free GIO connection.
The lamp can either be used exclusively for this function or as a ‘shared warning
lamp’ for several functions. Notes in this respect, see chapter 6.28 ‘Freely config-
urable functions’, page 125.
