Vacuum pump monitoring
The seizure of the rotor in the vacuum pump of a SMD assembly machine is prevented.
Independent monitoring of the permissible operating range of the power supply for the vacuum pump motor using the window function.
As soon as the power drawn by the pump leaves the permissible range, for example an overload because the blades are blocked, the relay output is tripped, and a contactor switches the pump off. The fault condition is detected and signalled by a vacuum sensor on the assembly machine, and the assembly procedure is stopped.
– Early detection and prevention of pump damage
– Motor protection
– Minimisation and prevention of downtime
