3. Description
The warning device is designed for lifting units that require a self-powered warning device.
The warning device creates an audible warning signal as soon as the vacuum falls below approx. 600 mbar.
It also monitors vacuum drops and increases.
No warning signal occurs when the vacuum drops very quickly (lowering the workpiece) or increases very quickly
(picking up dense work pieces with a small suction plate). Nor does a warning signal occur if the vacuum is lower
than approx. 70 mbar.
