Operating mode selector switch PITmode

The operating mode selector switch PITmode provides two functions in one compact unit: The control of access rights and the selection of the operating mode. The operating mode is selected by inserting a transponder key and pressing the pushbutton allocated to the relevant operating mode.

Each key is individually coded, which prevents manipulation. The administrative work is reduced because the functions of several mechanical keys can be combined within one transponder key.

As an option, the operating mode selector switch is also available with pictograms for machine tools – ideal for international applications. The operating mode selector switch is perfectly suitable for plant and machinery in which various control sequences and operating modes are used.

• Safe switching of operating mode through self-monitoring
• Pushbuttons available with/without pictograms for machine tools
• Selected operating mode and authorisation level can be identified quickly and read via LEDs, without fear of manipulation
• The operating mode is safely evaluated in the control system due to the RFID transponder key
• High level of manipulation protection due to universal coding
• Saves space, as operating mode selector switch and access authorisation are combined in one unit

Five selectable operating modes; e.g.:

• Automatic mode
• Adjustment mode (with enabling switch)
• Manual override under restrictive conditions (with enabling switch)
• Special mode/process observation (without enabling switch)
• Service mode

• Supply voltage: 24 VDC, -15 % to +10 %
• Ambient temperature: -20 to 60 °C
• Protection type: IP 65 (built in)
• Evaluation with configurable safety systems PNOZmulti and control systems from the automation system PSS 4000
• For applications up to PL d of EN ISO 13849-1 or SIL CL 2 of EN 62061 when selecting the operating mode
• Dimensions in mm (H x W x D): 55.0 x 98.0 x 42.3

PITmode can be used with plants and machinery that implement various control sequences and operating modes. Each user receives a coded key that provides selective access to the machine according to the users abilities.
