(3) Connecting to run terminals
Terminals 4, 5 and 6 are the ones for run output contact point and the contact point will be in operation
when the controller activates the run function. The fifth crank contact point is a shared terminal while
terminals 4 and 5 are for the contact point b and terminals 5 and 6 for the contact point a.
Contact points a and b start to operate when the engine reaches its designated normal speed RPM.
The diagram shows wiring to operate AC220V lamp. The shared terminal is for 220V inputs the run
lamp turns on when the contact point a starts to operate.
(4) Connecting to over speed
Terminals 7, 8 and 9 are the ones for over speed output contact point and the contact point will be in
operation when the controller activates the over speed function. The eighth over speed contact point
is a shared terminal while terminals 7 and 8 are for the contact point b and terminals 8 and 9 for the
contact point a.
Contact points a and b start to operate when the engine reaches its designated over speed RPM. The
diagram shows wiring to operate AC220V lamp. The shared terminal is for 220V inputs the over speed
lamp turns on when the contact point a starts to operate.
(5) Connecting to CAN communication
Terminal 10 is for CAN-L communication and terminal 11 for CAN-H communication. CAN-H and
CAN-L are used for CAN communication with remote control and monitoring of the controller opera-
tion. The communication code is based on J1939.
(6) Connecting to RS232 communication
D-SUB 9pin (female) is for RS232 communication for connection to external PCs or hosts.
It can configure system parameters of the controller or communicate with analytic applications.
