4.2.46 Vibr Setting
In the menu “Vibr Setting”, set parameter values related to sensors that monitor the Vibration level of the
Pump/Side Chanel Fan.
To detect and protect the Side Channel Fan against abnormal vibrations, the unit can be equipped with a vibra-
tion sensor.
If FlexPAK is equipped with a vibration sensor, set the vibration sensor parameters in Parameter Vibr Setting.

MaxS = 1000 → (1000/100) = 10 mm/s Max Set Vibration limit setting
MaxR = 1000 → (1000/100) = 10 mm/s Max Reset Vibration limit setting
Ax = 0 (Fan = Off Shows Max SET vibration limit setting
T = 10:00 s Alarm delay timer
MaxS = Set Vibration Threshold
Maximum accepted vibration signal. If the Vibration signal passes above MaxS, the FlexPAK unit vibration alarm
is activated. When the Vibration Alarm Delay Timer is elapsed = T, the unit stops.
MaxR = Reset Vibration Threshold
If Vibration Alarm is activated, and the Vibration Alarm Delay Timer is not elapsed = T>0 and the Vibration signal
pass below MaxR, the alarm is reset and FlexPAK is not stopped. Always set MaxR = MaxS!
Ax = Vibration Sensor Signal
If FlexPAK is equipped with a vibration sensor the input signal value is;
0 mm/s = 2Volt signal and 24mm/s = 10V Volt signal.
If FlexPAK is not equipped with a vibration sensor, the input signal is 0 volt.
Moreover, with the software sensor scaling 0v is approximately -618 units,
-6,18mm/s, this is irrelevant cause the sensor signal has only a positive sign.
The minus sign comes because the input signal is 0V and it is below 2V = 0 mm/s, in fact, this means that there
is no need to have a jumper on the vibration sensor input to disable the stop function.
T = Alarm Delay Timer
This timer is protection against temporary vibration peaks that occur when the unit is Cleaning, Accelerating,
Breaking and against Air Oscillations that occur at low speed. The delay time lets the signal get stable before it
activates the vibration alarm.
