4.1 Operating routine

4 Operating Instructions

4.1.8

Safety stop

If the separator begins to vibrate excessively
during operation, stop it immediately by pushing
the safety stop. The separator motor is switched
off.

•

Keep the bowl filled during the run-down to
minimize the excessive vibration.

Evacuate the room. The separator may be
hazardous when passing its critical speeds
during the run-down.

DANGER

Disintegration hazards

Never discharge a vibrating separator.

CAUTION

Disintegration hazards

After a safety stop the cause of the fault must
be identified.

If all parts have been checked and the cause
remains unclear, contact Alfa Laval for
advice.

Hazard!

009

Push the safety stop!
