Safety Circuit Inputs (Safety Motion)

Input signals of the safety circuit (safety motion) are important for the safety. With taking the following points into consideration, construct the circuit by useing mechanical relays for all.
For details about the entire structure of safety circuit, refer to Safety Circuit (Safety Motion).

Precautions for Connection

1. Two circuits connected in parallel using a single contact or an always-shorted circuit will be interpreted as an external circuit error. It makes the circuit inoperative.
2. If an inconsistency between each safety input signals continues over a certain period of time (about 0.5sec), an error occurs.
