SAFETY TEST
Permanently closing the contact enables automatic closing.
With DIP1=ON the closure of the contact activates an opening ope-
ration.
With DIP1=OFF the closure of the contact activates an opening or
closing operation in the following sequence: open-stop-close-open.
Note: if automatic closing is enabled, the stop is not permanent but
at a time that is set by the TC.
The closing manoeuvre starts when the contact is closed.
All operations are stopped and/or blocked when the contact is opened.
(reopening) during a closing operation.
Opening the safety contact stops the current operation.
To enable the emergency stop function (e.g. with a specific red but-
ton), connect the opening and closing controls to terminal 9 instead
of 1 (9-3, 9-4, 9-20).
Permanently opening the safety contact enables the operator pre-
sence dependent function.
In this state, the opening (1-3/1-20) and closing (1-4) controls fun-
ction only if held in the pressed position, and the automation stops
when the controls are released.
All safety switches, the step-by-step control and the automatic clo-
sing function are disabled.
The closing of the contact activates a partial opening operation of
the duration set with the RP trimmer.
Once the automation stops, the partial opening control performs
the opposite operation to the one performed before stoppage.
The opening of the limit switch contact stops the closure operation.
The opening of the limit switch contact stops the opening operation.
