4.6.12 Control option CNO
This document assumes the reader is familiar with the SAE J1939 standard. Terminology
from the standard is used, but not described in detail. See section 5 for information on the
CAN Bus operation and communication protocol.
4.6.12.1 General installation data
Voltage is to be directly connected to the actuator. All motion and protection on the CAN Bus option is
handled through the CAN messages including overload protection. Please see section 5 for more details
on the messages. The actuator can also be manually forced to extend by applying + Vdc to pin 6 (violet
wire) and to retract by by applying + Vdc to pin 5 (orange wire). When this is done the actuator will move
with its maximum allowed settings.
