8.3 How to Act in Case of an Emergency
If a hazardous situation occurs, or if you need to avert a potential danger, quickly set the device to a safe state. The type of EMERGENCY STOP circuit used for the device is to be determined depending on the hazards and operating conditions and is the sole responsibility of the operating company. It is for this reason that AWH can offer the operating company, solely as a precautionary measure, a few points of reference and notes to be observed and to be integrated into the operating company's hazard assessments. – The working steps listed in section 7.2 Switch-off Procedure must be adhered to for switching off the device. – The EMERGENCY STOP circuit must be designed in such a way that the machine or system operator can actuate it immediately in the event of an emergency. – Switching off with the “ EMERGENCY STOP ” in case of emergency is designed to disconnect the entire machine from the supply voltage without delay in order to eradicate the risks caused by electrical voltage immediately. – Shutting down in case of emergency using the “ EMERGENCY STOP ” is intended to prevent risks which cause hazardous movements as soon as possible. – The EMERGENCY STOP must have priority over all other functions and actuations in all operating modes.
– Resetting must not cause the plant/machine to start up again.
