* J1939-15 refers to Twisted Pair and Shielded cables. The standard/default cables delivered with LA37 CAN
do not comply with this.
Specification
Compatible with the SAE J1939 stand-
ard. Uses CAN messages to command
movement, setting parameters and to
deliver feedback from the actuator.
See the LINAK CAN bus user manual.
Actuator identification is provided, using
standard J1939 address claim or fixed
addresses.

Note: Do not swap the power
supply polarity on the brown and
blue wires!
Power supply GND (-) is electri-
cally connected to the housing
Current limit levels can be adjusted
through BusLink
If the temperature drops below
0°C, all current limits will
automatically increase to 30A
On/off voltages:
> 67% of V IN = ON
< 33% of V IN = OFF
LA37 with CAN bus does not
contain the 120Ω terminal
resistor. The physical layer is in
accordance with J1939-15.*
