Monitoring
Release of the monitored input element with a falling edge of the corresponding monitoring
input. This is always necessary if the monitored input element is to b e switched.
Example: start of a drive only after confirmation by the operating personnel.
With a monitored startup type, an additional connector is provided to connect the startup
element. Here, continuous behaviour for the monitoring of the input elementduring the
startup phas can be configured.
•
Start test
Manual start after equipment reset or after interruption of the preset safety circuit, including
the test of the connected monitoring equipment. The monitoring equipment must trigger
once in monitoring direction, and it must switch on again afterwards. Afterwards, normal
operation follows. This one-time triggering of the input element during the start (or during
reset) of monitored equipment warrants the functioning of the input element at the time of
start. A start test can be carried out for all elements except the selection switch for the
operation mode.
An activated start test is indicated by a red rectangle around an inserted function block
Every input block can carry out an automatic function test (= start test). In total, two switch
elementsc an be configured for the start test.
