After filter pressure monitoring MagicControl 4.0 (CM40)
315B2 / 315 B4
5. The electrical switching points of the dynamic pressure
monitors (315B2 and 315B4) must also be set to the value
Δp
ATEX: Stop powder at the corresponding exhaust air volume.
Alarm
1.
Adjust the throttle valve on the after filter so that the fan Δp shows
the pressure value 2
“Alarm”
.
2. Measure air volume in the ducting with an anemometer.
– If the air volume is correct, continue with step 3.
– If the measured air volume flow does not correspond to the set
value, the flap position on the after filter must be changed until
the volume flow measured with the anemometer corresponds to
the set value. (in this example 10,800 m³/h)
3. Enter actual value of system pressure
