Coils and contacts
Function block coils initiate the functions of the function
block and monitor the connected safety transmitters.
The contacts of a safety function block confirm the enable
conditions present, selected operating modes or indicate
errors.
Coils
The ZM..SA function block coil is used to start the monitoring
function of the function block.
You can link the coil, for example, with the Enable contact of
another safety function block.
The reset coil ZM..RE resets the function block in the Manual
Start (MST) and Controlled Start (CST) modes and starts
normal operation. Used in the safety circuit diagram.
The function block is enabled either in the safety or in the
standard circuit diagram with its enable coil ZM..EN.
Contacts
The contact ZM..QS indicates the standstill of the motor in
the safety circuit diagram. This signal can be used for
example for the release device of a guard.
If you wire the contact ZM..ER in the standard and/or safety
circuit diagram, it indicates the presence of an error by
closing.
