When performing CE certification of grain packing machine, When designing the start equipment, pay attention to the following:
Mechanical equipment must only be started by a voluntary action of a controller under specified use.
The above requirements also apply to:
——When the mechanical equipment is stopped, restarted for whatever reason;
——When there are significant changes in operating conditions (such as speed, pressure, etc.).
Unless this restart or change in operating conditions does not pose a hazard to the exposed person.
This basic requirement does not apply to restarts or operating condition changes resulting from the normal sequence of an automatic operating cycle.
When the mechanical equipment has several starting controllers, and the operator may be in danger due to accidental contact, additional devices (for example, starting devices or selectors must be installed so that the starting mechanism drives only a part of them at a time) to avoid these danger.
Automated equipment that operates in an automated manner must be restarted immediately after a shutdown, once the safety conditions are met.
