If the monitoring system detects that the dp across the Main filter passes a high dP limit, it activates the Main
Filter Warning and Alarm delay timers. When the Warning delay timer elapses the “Warning! Main Filter Clogged”
is displayed after a time. When the Alarm delay timer elapses, the fan stops and simultaneously the “Alarm! Main
Filter Clogged” is displayed.
Warning and Alarm delay timers have different settings. The warning delay time is always shorter than the
Alarm delay time.
See Message, Warning! Main Filter Clogged, “Alarm! Main Filter Clogged” and Parameter MFDPS-Wr and MFD-
PS-Al.

Set Analog Sensor monitoring on/off

The Analog Sensor uses ambient pressure as a reference to the measured pressure. To get the Main filter dP
pressure with a positive sign, calculate it with the formulas;
Filter System dP
Calculation if only the Main Filter Sensor installed.
MFPP = Calculated Pressure drop across Filter System.
MFP - PP = MFPP
→
Filter System Pressure drop from the duct to pump.
Main Filter dP
Calculation of both the Main filter and Control Filter sensors are installed.
MFCF = Calculated Pressure drop across Main Filter.
MFP - CFP = MFCF. “Main Filter dP”
Setting high dP limit, Max dP limit across Filter System
These parameters are used if only the Main Filter Sensor is installed.
dPSS = dPSR = Max dP limit across Filter System
Setting high dP limit, Max dP limit across Main Filter
These parameters are used if both the Main and Control filter sensors are installed.
dPDS = dPDR = Max dP limit across Main Filter
