2. The extractor has switched to
braking during extraction. The
extractor will not restart.
3. The yellow light starts flashing upon
braking. The brake switches off and
the extractor remains locked.
4. No signal comes from the machine´s
mechanical rotation guard upon
braking (at the point where the drum
begins to rotate anticlockwise).
The drum rotates anticlockwise for
approx. 1 1/2 minutes and then
braking switches off and the yellow
light starts to flash (time varies
according to machine type, load and
frequency).
The extractor´s lid remains locked.
5. The signal from the machine´s
mechanical rotation guard is
constantly active. Braking switches
