Sequence function : Used to prevent alarm output that is caused by excessive
vibration during machine startup. Block off the
DANGER/ALERT alarm, or switch the alarm setup value to
another number magnified by setup number.
Sequence Setup : Block off

Suppression function : If the vibration value is less than the setup value,
this function is forced to suppress the measured vibration
value and recorder output.

! WARNING
In case the SEQ. magnification number is setup from 2 to 10, the
alarm setup value magnified by setup number while the SEQ.
circuit is in progress should stay at or lower than 110% of the
maximum monitor range. If the number is more than 110% of the
monitor range the alarm may not output.
