KST – KROMSCHRÖDER SYSTEM TECHNOLOGY
This module limits the ignition capacity of the burner during the start-up procedure until the operating signal of automatic burner control unit is received. Limiting the capacity results in safety times for the “start-up” which can be calculated using the “Project Planning Guide – Determining the safety time”.
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.
