Default
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 moni-
tored is active. The Output Enable signal will turn OFF if the input is inactive or
if an error is detected for the function block.
All errors are turned OFF and all timers are reset at the start of operation.
Outputs are turned ON or OFF according to the input status.
Refer to information later in this section if the function test has been enabled.
