HBC-series V7 LV+MV
Emergency disconnection circuit / posibility of automatic traction connecting
(this function is available only for controllers with driving board
CN-B15, i.e. for HBC 25063-3, 140120-3)
Condition for applying is feeding of the control board by external v14 V that is present even after disconnect-
ing the traction battery.
If your application requires the ability
to disconnect the traction battery during operation
(i.e. the engine is running) by security but-
ton, shock sensor, etc., you must use this connection. This function can also be activated in the setting of parameters (parameter
P58
).
The system also provides
automatic connection sequence to traction voltage
(switching relays and contactors then after turning the
switch
CON
), parameter
P92
. This feature can be used independently of the emergency disconnecting. This function is suitable if you
need to automatically control the inputs and antispark to traction and is not used BMS to ensure these functions.
Recommend connecting for HBC 25063 (140120):
*)
The possibility of emergency disconnectio with using
BMS-2 system
(output
PO 1
of the
BMS-2
unit).
In this case, it is necessary to cancel the jumper
K20/2 to K20/4.
To indicate turn-on the main power contactor
(= traction power supply connection) can be used
either bulb 12V / or 1 to 5W LED with
corresponding serial resistor.
