General Description
The Safety Gate Monitoring function block monitors the status of a safety
gate. Safety gate status is monitored using an input signal from a safety door
switch or safety limit switch connected to the door.
The Output Enable signal will turn ON if the input from the switch being mon-
itored is active. The Output Enable signal will turn OFF if the input is inactive
or if an error is detected for the function block.
