FlexPAK
4.2.49 CFdP Setting
In the menu “CFdP Setting”, set parameter values related to sensors that monitor the Control Filter.
Control Filter monitoring can be done by an analogue pressure sensor or digital dP Switch. When the monitoring
detects hi dP across Control Filter the “Alarm! Control Filter Clogged” is displayed and the FlexPAK fan stops.
See Parameter CFDPS-Al and Alarm Message, “Alarm! Control Filter Clogged”.
Digital dP Switch monitoring
The default setting for “CFdP Setting” is the monitoring of dP Switch.
The only requirements to install a dP Switch are to replace the pre-installed jumper with a dP switch. The Dp
Switch requirements are normally closed functions when measured dP is less than the set value of the dP
switch.
Analog dP Sensor monitoring
If an Analog sensor is installed, set parameter Stat = On to activate analogue monitoring.
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 formula;
(CFP-PP) = CFPP “Control Filter dP”, PP = Pump Pressure.
Setting high dP limit, Max dP limit across Control Filter
Maximum accepted dp across Control Filter if dp pass above (parameter = on) the “Alarm! Control Filter Clogged”
alarm activates, and the FlexPAK stops. Parameter On = Off

4.2.50 MFdP Setting
In the menu “MFdP Setting”, set parameter values related to sensors that monitor the Control Filter. Set para-
meters in this menu if an analogue pressure sensor is installed
The default setting for “MFdP Setting” is monitored by a dP Switch. To install a dP Switch, remove the jumper on
the terminal and replace it with a dP switch. The dP Switch requirement is normally closed function when meas-
ured dP is less than the set value of the dP switch.
Parameter “Stat = Off”
If an analogue pressure sensor is installed set parameter “Stat = On” to activate the analogue sensor monitor-
ing.
