Safety 3 Safety 3.1 Intended use The operating mode selector switch is suitable for machines that can be operated in multiple operating modes with different safety functions and/or work procedures.
Safety 3.2 Safety regulations 3.2.1 Use of qualified personnel The products may only be assembled, installed, programmed, commissioned, operated, maintained and decommissioned by competent persons. A competent person is a qualified and knowledgeable person who, because of their training, experience and current professional activity, has the specialist knowledge required.
Function description 4 Function description The operating mode selector switch enables you to switch between 3 different operating modes (operating modes OM1, OM2 and special operating mode OM5 (Service)). One pushbutton each is available for OM1 and OM2. For special operating mode (Service), pushbutton OM1 must be operated for a certain period (see Monitoring of operating time [ 56]). Each pushbutton is assigned a monitored semiconductor output (see Operating mode interface [ 20]).

A switch between operating modes must be enabled via a transponder key.
Function description NOTICE It is essential to note: – The configuration may only be performed by a competent person. – The configuration must be performed when the supply voltage is switched off. – The configuration is adopted as the device is started up, provided the switch setting is valid. If not, the device switches to a "Device error" fault condition. – During operation, the DIP switch setting is monitored for any change.

Function description 4.2 Operating mode interface The operating mode interface consists of the monitored outputs SOM1, SOM2 and SOM5 (see Block diagram [ 14]). "SOM" stands for "Safe Operating Mode". The outputs are assigned to buttons, which can be used to select an operating mode if they have the relevant authorisation (transponder key): Button Output Operating mode 1 SOM1 OM1 SOM5 OM5 SOM2 OM2 2 4.2.

Function description 4.4.2 Communication mode for downloading the Key ID number The unique Key ID number for the relevant transponder key is downloaded to the higherlevel process control system using a defined protocol, depending on the coded communication mode. The communication mode is coded on the Key ID interface of the operating mode selector switch (jumpers available/not available). The operating mode selector switch detects the coded communication mode at each power-on.
Function description 4.4.2.2 Handshake-controlled communication mode With handshake-controlled communication mode, the download of the Key ID number is started by the control system (Request). Features of this communication mode: } Download starts via a request to the control system, once the transponder key is connected } Download is repeated by a renewed request to the control system } Variable bit rate (min. 2 PLC cycles per bit) } Download on 1 data line } Min.
Function description 4.4.2.3 Advanced communication mode In advanced communication mode, the download of the Key ID number behaves in the same way as the handshake-controlled mode. It differs from the handshake-controlled communication mode in so far as an operating mode lock and operating mode pre-selection can be configured (see Key lock [ 41] and Operating mode pre-selection [ 44]).

Wiring 6.3 Connection to a control system When restarting, the device is in BA1 or in the last selected operating mode, depending on the device configuration. Depending on the application area and its respective regulations, the operating mode selector switch can be used up to SIL CL 2 (EN IEC 62061) and up to PL d (EN ISO 13849-1), if the operating modes are evaluated by a safety control system with safe "1oon" evaluation.

Operation 7 Operation Switch-on behaviour INFORMATION After the operating mode selector switch is switched on (Power-On) or after supply voltage is returned (reset), operating mode OM1 is selected automatically. This also applies if no transponder key is connected, or a transponder key is detected but is invalid. Behaviour in the event of an error in operating modes OM1/OM2 NOTICE In the event of an error, the unit does not change operating mode.
Operation 7.1 Select operating modes OM1/OM2 Prerequisites } A transponder key with the relevant authorisations must be present. } The operating mode selector switch must recognise the transponder key as valid. } The transponder key must be present at the operating mode selector switch for the whole time the button is operated. } Several buttons may not be operated simultaneously when selecting an operating mode. Procedure 1.
Operation 7.2 Select special mode (service) Prerequisites } A transponder key must be available with authorisation for special operating mode OM5 (Service). } The operating mode selector switch must recognise the transponder key as valid. } The transponder key must be present at the operating mode selector switch for the whole time the button is operated. } Several buttons may not be operated simultaneously when selecting an operating mode. Procedure 1.
Operation 7.4 Switchover delay t1 Once a button has been released, the assigned output on the operating mode interface switches to a "1" signal after the switchover delay t1 has elapsed (see Technical details [ 62]). This defined switchover delay guarantees that only one operating mode at a time has a "1" signal at the assigned output.

Operation 7.6 Diagnostics The operating mode selector switch has various options for displaying status information: 7.6.1 } Interface for status information (SIo0 … SIo3) } Button backlighting } Authorisation display Status information about the interface for status information Various status information can be signalled via the interface for status information (see Block diagram [ 14]). The status information can be evaluated through a control system (see Interface for status information [ 20]).
Operation 7.6.2 Status information about button backlighting Buttons 1 and 2 (see Control elements [ 9]) have button backlighting. Button backlighting is used to display which operating mode is active; i.e. which output (SOM1, SOM2 or SOM5) has a "1" signal.
Operation 7.6.3 Status information about authorisation display If a transponder key is inserted in the slot of the operating mode selector switch, its authorisations are displayed via the authorisation display LEDs (see Control elements [ 9]).
