(1) The override function is allowed :
- if the OSSDs outputs of the protective equipment are open and an object is inside the
protection field,
- if the contacts of the push-buttons are closed within the preset time frame.
(2) The override function is automatically interrupted as soon as the OSSDs
outputs switch ON when the protection field is released.
(3) The override function is not allowed if the protection field is clear.
2.4.5 Manual restart of the module
The manual restart of the module is necessary after each power reset and after each
time the OSDs outputs switch off .
The opening of the OSDs outputs may be due to one of the following events :
− interruption of the protection field while the protective equipment is not muted,
− failure of a sensor SM or EM,
− module internal failure,
− failure of the FSD relays used to interface the module with the machine control
circuitry.
