When an error is encountered, the port in question will enter ACK OFF mode, making it 

unable to send messages or issue ACK responses. 

The error state will return to normal after measurement completes.

When a port enters an error state, verify that the wiring and CAN communications condi-

tions are correct. 

CAN input port 1 (left) and 2 (right)

CAN signal input terminals. CAN1 and CAN2 are independent and can be 

connected to different networks. 

CAN LED1

• Turns green when a CAN message allo-

cated to the port 1 output channel is input.

• Turns red when port 1 experiences an error. 

CAN LED2

• Turns green when a CAN message allocated 

to the port 2 output channel is input.

• Turns red when port 2 experiences an error.
