Fig. 5: A971 emergency stop board
The emergency stop board A971 has a connection strip CON402 (Fig. 5, No. 1), via which you can use the
two additional normally closed contacts of the emergency stop. In addition, there is a normally open contact
on the connection strip. This operates on a pulse basis and does not establish a permanent contact.
