8.4 Interface Description 8 Technical Reference
The vibration monitor shall include self check
function to be performed at least at initiation of
STARTING.
If vibrations exceed the second alarm level the
separator shall be stopped the quickest way
possible and it shall not been restarted until the
reasons for the unbalance have been found and
measures to remove them have been taken.
Signal processing in STARTING:
If vibrations exceed the second alarm level the
separator shall be stopped automatically by
SAFETY STOP.
If the self check system triggers, an alarm shall
be given and an automatic stop by NORMAL
STOP shall be initiated.
Signal processing in RUNNING:
• If vibrations exceed the first alarm level an alarm
should be given. Vibrations of this magnitude
will reduce the expected life time of the bearings
and should therefore be eliminated.
• If vibrations exceed the second alarm level the
separator shall be stopped automatically by
SAFETY STOP.
• If the self check system triggers, an alarm shall
be given.
Signal processing in STOPPING:
• If the self check system triggers, an alarm shall
be given.
Signal processing in NORMAL STOP:
• If vibrations exceed the second level the system
shall turn over automatically to SAFETY STOP.
760 Cover interlocking switch (optional)
The separator is equipped wi
th a interlocking
switch to detect if the co
ver is mounted.
Signal processing in STAND STILL:
• The circuit is closed when the cover of the
separator is mounted.
• The interlocking switch should be connected
in such a way that starting of the motor is
prevented when the separator cover is not
mounted.
