NOTE
Temperature monitoring is implemented in the VCI. This protects the VCI
against damage from overheating.
When a critical temperature is reached, the user is warned by a fast flashing red
LED. If the user does not react and the temperature rises over the limit value,
the VCI is switched off.
The VCI has to cool down for approximately 10 minutes before it can be
reactivated.
3.4.2 VCI Battery
3.4.2.1 Buffering
To prevent immediate shutdown of the VCI during periods in which the vehicle's
power supply is switched off (e.g. in order to reset electronic control units in the
vehicle), the VCI is capable of buffering itself for a brief period between 20 and
60 seconds.
The last 10 seconds of buffering are indicated by slow flashing of the red LED.
With the VCI Configuration Manager the buffer settings can be changed
between 20 and 60 seconds or turned off.
3.4.2.2 Charging
The battery will be charged each time the VCI is connected to the vehicle and
the vehicle's power supply. After power-up, the battery is charged for 5 minutes
with a high current. After this time period, charging switches to a mode with low
current.
The battery indicator flashes if the buffer function is not possible. The VCI shuts
down immediately whenever the power supply is disconnected.
In case of long storage periods a deep discharge of the battery is possible. In
this case a minimum charging time of 20 minutes is necessary to bring up the
batteries to their normal use range and to permit the VCI buffering for one cycle.
Overcharge of the batteries will be avoided.
NOTE
Over temperature protection of the batteries is monitored by a temperature
sensor.
