Reasons for an active safe mode:
1) Connection failure with safety-related coupling:
•
The cause of this error is not immediately identifiable or cannot be at-
tributed to the operating panel. When reactivated, the coupling process
must be rerun to ensure that the entire system is functioning properly. (E.g.
cable break in the installation).
2) Internal HGW hardware error (e.g. switch error)
•
If an internal or Safety error is found, the panel must be returned to
SIGMATEK.

Turning Off
The On/off switch can be configured via LASAL Class 2. The application engineer can define
procedures for turning the operating panel off. Alternatively, a hard shutdown is possible by
pressing the On button for at least 3 seconds (see 6.6). To avoid an undesired emergency
stop, the operating panel must be decoupled before actively shutting down.
10.4.7
Evaluating Operating Elements
The operating panel sends all statuses to the control, through which further actions can be
set. Display (display, LEDs...) are initiated by the control.
The HGW 1033-3 sends the following operating element statuses to the safety-related control
SCP 111, which can evaluate and process the information.

Key switch
•
Emergency stop
•
Confirmation switch
