    basic data
    alarm threshold (± 10%) 0.25 … 5 in / s pk 4.5 … 90 mm / s RMS" [1]
    frequency range (± 3 dB) 420 … 60,000 cpm 7 … 1,000 Hz
    hysteresis (relative to the alarm threshold) 3, 6, or 10% [1]
    enviroNment vibration level (below is interpreted as downtime) absolute or relative to the threshold [1]
    EnviroNment vibration level (relative to the alarm threshold) 1 … 40% [1]
    MAVT-process (simply setting the alarm threshold to twice the current vibration amplitude) Can be optionally activated [1]
    transverse acceleration sensitivity < 3%
    switch-on delay (prevents tripping directly After applying the supply voltage) (± 1 s) 3 or 20 s [1]
    start delay (prevents tripping during the start-up process) (± 1 s or ±1 min) 1 … 60s oder 1 … 30 min [1]
    start delay: boost the threshold 2 x, 4 x, 8 x or release completely prevented [1]
    Activation of the start-up delay optional [1]
