Automatic connection to the traction
If you choose to connect and disconnect traction automatically using antispark relays and main contactors, there are two possibilities of
their control.
If you use option
a)
or
b)
define the parameter
P92
.
a) Activation using the switch V1
(feeding of the electronics connecting).
Activation electronics starts (among other things) the
automatic start sequence
,
when the first antispark relay switches and after filtration capacitors charge is automatically
connected traction voltage closing the main contactor
.
Deactivation switch (disconnect the electronics from feeding) as antispark relay and the main contactor drops out and
disconnects controller from the traction voltage
– this disconnection you may do only when the motor is stopped
!!!
b)
Control function using the switch CON
, „safety switch“
(KEY, „
ignition key
“).
Closing (activating) to start the automatic
start sequence when the first antispark relay switches and after filtration capacitors charge is automatically connected traction
voltage closing the main contactor
,
as in the case
a)
.
But here, unlike the case of
a)
,
you can at any time deactivate this switch
.
This cause in the first step disconnection and stop
the motor and in second step then drops as antispark relay and the main contactor and disconnects controller from the traction
voltage
.
Therefore, this disconnection can be done at any time during engine run without damaging the controller
.
The re-activation this switch is again start all steps to safety connecting traction voltage, etc
. (
in contrast to function
„
Emergen-
cy disconnection
“,
when after disconnecting the contactor cannot be invoked again its connecting
–
initially it is necessary
turned off and on the whole system
).
Emergency disconnection
This function provides
automatic and safe
traction
battery
disconnection
from the controller
in the event of
an emergency,
accident
, etc
.
whenever you need to
disconnect
the battery during
engine run
,
without damaging
controller.
Disconnecting
sequence
runs automatically
when, is activated
a "safety
switch
ED
“,
which turns off the
main contactor.
