OptiControl ISC08 Adjustment instructions
ATEX: Stop powder
1. Adjust the throttle valve on the after filter so that the Fan Δp displays
the pressure value 3 “ATEX: Stop powder”.
2. Measure the actual 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 9,600 m³/h)
3. Enter the actual value of the Δp ATEX: Stop powder manually
under 6.
4. The electrical switching output in the two differential pressure
switches (315B1 and 315B3) must now be calibrated to the exhaust
air value “ATEX: Stop powder”.
Setting the switching output
This function is used to set the switching output to “switched through”
for a defined pressure.
– Set air volume value to Δp ATEX: Stop powder at which point
the electrical contact should change status. (NPN 4)
– Press the “S” key for 5 seconds until the LED flashes quickly
(= value is stored)
The LED lights up as soon as the defined pressure is reached or
exceeded.
Important:
The M = Mode key must not be pressed.
– The M key is used to adjust the zero point deviation
