Page 7: Disclaimer And Warranty
Safety Time Control Device Appropriate use also includes compliance with: EN ISO 13849-1, Safety-related parts of controllers, EN 60204-1, Electrical equipment in machines. For further information please refer to the above mentioned documents. ATTENTION! The user is responsible for integrating the device into a safe overall system. For this pur- pose, the overall system has to be validated, e.g. -
Page 8: Features
Safety Time Control Device SCB This means that the connected load is switched off as soon as a request from connected sensor elements or diagnostic measures detects a dangerous state, e.g. caused by a component fault. Since process-related applications in particular have high demands on availability, limited availability can also have significant consequences. -
Page 9: Functions
Safety Time Control Device 7. Functions The safety time control device SCB is conceptualised for the safe isolation of safety circu- its according to EN 60204-1 and can be used in safety applications up to, PL e, Cat. 4, SIL 3 as well as on furnaces in continuous operation according to EN 50156-1 and EN 746-2. -
Page 10: Functions Of The Safe Semiconductor Output P1 And O2
Safety Time Control Device SCB 7.4 Functions of the safe semiconductor outputs O1 and O2 Taking into account the selected configuration, the safe PNP semiconductor outputs switch on when the safety circuit is closed. Opening the safety circuit leads to a switch-off. 7.5 Functions of the safe relay contacts 17-28 and 27-28 Taking into account the selected configuration, the safe relay contacts switch on when the safety circuit is closed. -
Page 11: Application Example
Safety Time Control Device ATTENTION If the function switch-off delay with automatic re-trigger function is used, the automatic reset at the moment of re-triggering has to be considered separately, since the monito- red, manual start is disabled in this moment. 8. - Page 12 Safety Time Control Device SCB With the selected configuration Pr06, which allows a monitored, manual start with automa- tic re-trigger function as well as a time-delayed switch-off of the safe relay contacts, the SCB-02 filters a short-time triggering of the connected pressure-switch up to 10 seconds. If an overpressure is detected, the time delay at the SCB-02 is triggered.

Page 19: Configuration Of The Scb
Safety Time Control Device 13. Configuration of the SCB The SCB is delivered with the default configuration "Pr00". With this configuration, the device evaluates the safety circuit and the reset circuit according to the configuration table. However, no delay time is executed. A parameterization of the delay time is therefo- re not possible. - Page 20 Safety Time Control Device SCB After the menu item "Pu" has been displayed for approx. 2 seconds, the PUK can be ente- red (see Figure 19). Enter Enter Enter (2s) Figure 19: PUK procedure 1. bis 3. PUK enty: first digit of the PUK is set by turning the push/rotary button. The first PUK digit is saved by pressing the button briefly and the second PUK digit can be set in the same way as the first one.
