126615-01 Tachometer Module 3500/50 3500 Rack Backboard

BENTLY 126615-01 monitor provides mechanical protection

126615-01 Trip Multiply
The 126615-01 value selected to temporarily increase the alarm (Alert and Danger) setpoint values. This value is normally applied by manual (operator) action during startup to allow a machine to pass through high vibration speed ranges without monitor alarm indications. Such high vibration speed ranges may include system resonances and other normal transient vibrations.
