(See “Vibration (Over All) Monitoring (Selection Table for Filter Set

Value P.5”.)

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.
