Voltage ranges of the on-board system
22926
The system monitors the voltage ranges of the on-board system.
The voltages mentioned here apply to the specified range ± 1 % (at 36 V).
Voltage [V]

Undervoltage
VBB15, VBB30:
If the controller was in the OPERATING mode, the controller shuts down.

< 8.0
Limited operating range
If the controller was in the OPERATING mode, then it continues to operate in this range without any
restrictions in case of voltage dips.

+36.0
Overvoltage (protected)
The device is not damaged by the voltage deviation.
If this condition on VBB15 / VBB30 in the OPERATING mode lasts longer than 10 s, the controller
changes to the FATAL ERROR state.
If this condition on VBB0...n in the OPERATING mode lasts longer than 10 s, the corresponding
output group changes to the COMPONENT ERROR state.
> +36.0
Overvoltage (unprotected)
In this area, the device is no longer protected and the behaviour is not predictable.
The device can be destroyed by this voltage.
► If such voltages are likely to occur in an application, provide for external protection!
>
Start conditions
22925
The device only boots when sufficient voltage is applied to the power supply connection VBB30 and to
VBB15 (= terminal 15).
In vehicles clamp 15 is the plus cable switched by the ignition lock.
This voltage must be provided by the on-board system of the mobile machine.
