Construction of Contact
1. Emergency stop switch or Stop switch (Direct opening action) (A1, A2)
Emergency stop switch or stop switch is available to connect to an emergency stop circuit. It remains locked when
operated. Contacts do not open the operator is locked (safety locking mechanism). Direct opening circuit function
ensures to open contacts even if contacts are welded.
2. Enabling switch (Direct opening action) (B1, B2)
The enabling switch consists of two contacts (OFF-ON-OFF). They can be wired so that the contacts can be monitored
mutually using two input points. Each contact works independently, so the end of the switch at operation, a time
difference between the two contacts may occur. Wire the enabling switch so that the contacts can be mutually
monitored using two input points. Design a sequence program in consideration of the time difference.
