KST – KROMSCHRÖDER SYSTEM TECHNOLOGY
Emergency stop of the heating system
The emergency stop or emergency off device is designed to enable the operator to shut down the gas supply to the system immediately. The emergency stop or emergency off device performs a fault lock-out of the system when actuated.
The function must comply with the requirements of the protective system to EN 746-2:2010 subclauses 5.7.2 and 5.7.3.
If failures or disturbances in the protective system can cause a hazardous situation or damage to the machine or product, suitable measures shall be taken to reduce the probability of occurrence of such failures or disturbances. The necessary measures and the extent to which they are implemented – either individually or in combination – depend on the level of risk associated with the application in question.
