In the case of heavy dust generators (e.g. blasting equipment), the time interval "emptying the
dust drawer" should be set to 5 hours, if necessary to 10 hours.
Automatic switch-on for automatic operation (see Fig. E at the beginning of this
document)
The switch-on threshold, which activates and deactivates the suction function when a connected electrical
device is operated, can be set.
When setting the switch-on threshold for handpieces, the control unit must be switched on for the first
measurement (stand-by) without operating the handpiece
For the second measurement (On), the handpiece should be operated at the speed at which the suction
is to be switched on.
For devices with standby mode, these should be switched on approx. 5 minutes before setting to
avoid incorrect measurements.
If there is an error with the switch-on function, the display "C" will blink and an acoustic signal is
emitted twice. Set the changes again. If necessary, select a higher speed for handpieces.
For detailed information on "Troubleshooting", see the instructions for use which you can down-
load from our website at www.renfert.com/p915.
After-run time of the suction turbine (see Fig. E at the beginning of this
document)
After-run time = the time between switching off a connected consumer and turning off the suction turbine.
There are 6 different times to choose from.

In order to prevent the suction from being switched on / off too often in the case of short interrup-
tions (for example when working with the handpiece), a higher time value can be selected.
