B014 Error message delay T = 50.0 secs.
B016 Debouncing of B001 T = 10.0 secs.
The pressure
monitoring must
indicate
no powder for
a defined duration, until
the signal will be
evaluated

The no powder signal
must be present for a
defined duration
For the adjustment and the operation of the powder transport,
the corresponding powder pump documentation must be
observed!
Powder flow detection
Overview
If craters form through the suction procedure in the powder container, the
powder flow can thereby be influenced negatively. In order to prevent this,
a pressure sensor measures the backpressure in the powder hose.
If the pressure decreases under a defined threshold value, the powder
container is lowered to the floor and lifted again, so that the craters can
be loosen.
