The related parameters of the built-in waveform of the instrument are introduced
as follows:
LV148 LV148
E-01 Long-term overvoltages
The component's resistance to long-term overvoltage is
tested. A generator control fault during driving operation is
simulated.
E-02 Transient overvoltages
Transient overvoltages may occur in the electric system due
to the switching off of loads and due to short accelerator tip-
ins. These overvoltages are simulated by means of this test.
Short
Endurance
E-03 Transient undervoltages
Transient undervoltages in the electric system may occur
due to switching on of loads. These undervoltages are simu-
lated by means of this test.
E-04 Jumpstart / recuperation
Jump starting of the vehicle is simulated. The maximum test
voltage results from commercial vehicle systems and their
elevated electric system voltages.
E- Slow decrease and increase of the supply voltage (without
06A energy storage )
The slow decrease and increase of the supply voltage is si-
mulated as it occurs during the slow discharging and charg-
ing procedure of the vehicle battery.
T1 Holding
Time
E- Slow decrease and increase of the supply voltage (with en-
06B ergy storage – Part 1 )
Checks will slow the supply voltage decrease to the energy
storage protection voltage, followed by energy storage
disconnection.
