Vario Basic systems are supplied with an external control unit. For systems with four isolation elements,
we supply a 4-port control unit.
Controller Front Display
The controller front display of the Vario Basic system
is equipped with a main power switch, an on/off
switch for the active isolation mode and several LEDs.
All switches and LEDs are depicted in Fig. 5.
After the controller has been switched on, the green „POWER" LED lights up and the blue LED starts
blinking.The blue LED indicates the isolation mode. Blinking of this LED means that the system is in the
initialization or stand-by mode. After approximately 30 to 60 seconds, the blue LED shines on and the
system is then running in the active isolation mode. This mode can be changed by pressing the on/off
button for the active isolation mode. The factory setting of the active isolation mode is "on".
Eight sensor-actuator units are integrated into the two isolation elements of the VarioBasic system. Each
unit is represented by a pictogram consisting of a circle with a sine symbol and an arrow printed on the
front panel. The sensor signals are displayed by the yellow LEDs and actuator outputs are indicated by
red LEDs, as shown in Fig 5. These LEDs flicker if extreme vibrations are present, or if there is a direct
excitation of the table top.
The LED pairs numbered from 1 to 4 correspond to isolation element B and 5 to 8 to isolation element A.
The arrows of the pictograms display the direction of the actuator force. The actuators 1, 4, 5 and 8 have
a vertical orientation whereas the other actuators 2, 3, 6 and 7 are placed in a horizontal direction.
Use the „power switch" in front of the control unit to turn on the Vario Basic 40/60/90 power.
Press the on/off button to activate/deactivate the active vibration isolation.
Overmodulation of the System
The Vario Basic system is designed to compensate vibration amplitudes up to 500µm/s for the 300 and
600 kg version and 550 µm/s for the 100 kg version. If vibrations significantly exceed this level the sys-
tem changes to the stand-by mode which is indicated by a flashing blue LED. After the overload excita-
tion has stopped, the active isolation mode will automatically continue. Some of the sensor or actuator
LEDs may come on and persist for a few seconds. Following a severe overload, the system may take up
to 30 seconds to reach full active isolation but normally, only a few seconds are required.
The active vibration isolation is automatically switched off during overmodulation of the system.
Once this interference has subsided, the system re-initializes and, after a few seconds,
automatically resumes active vibration isolation. This procedure does not require any action from
the user.
