1/min
The air flow generated by the fan may be monitored as
follows:
The static pressure is monitored by the pressure switch
(PZL) as long as it can be demonstrated that the dis-
play consequently shows an adequate and secured flow
of air, or the pressure switch (PDS) checks the flow of air
via the differential pressure on the orifice.
If there is no air pressure supplied or if there is no differ-
ential pressure on the orifice, the system will be blocked.
