Terminal assignment of the CAN bus terminals
ATTENTION
Damage to the installation and stock loss!
If, when designing the system technology, the use of
pressure transmitters / temperature sensors
at the refrigeration points of the 2nd CAN bus segment
(the one without pack controller) was
dispensed with
, we recommend in the unlikely event of a failure
of the system centre to
reactivate it as quickly as possible
!
Practical tip:
- Until the system centre is reactivated again,
temporary
solution
to exchange information (e.g. t
0
/ suction pressure) between the two CAN bus segments
CAN1 and CAN2.
-
The evaporator input sensor R5.x should also be connected in the t
0
via CAN bus operating mode.
This results in
improved emergency running characteristics
in the event of failure of the CAN bus
transmission. In standalone operation (failure of the CAN bus and without local pressure transmitter)
the sensors R5.x must be connected, see operating manual of the
Each CAN bus segment can have a maximum length of 500 m; the specified cable type is
LiYCY (TP)
. For further information about the CAN bus, see the operating manual “
