Adjust the parameters referring to relative pressure (sig-
nal 2) if a RPS is used:

 

Offset:

An offset can be carried out.
Adjustment range: 0  ... 99.99 bar

 

Min Alarm:

If the minimum relative pressure is reached, the relay 
is energized,   appears in the display, the LED flashes 
green and an alarm message appears in the submenu 
“Reports”.

 

Î

Select “Yes” or “No” to activate or deactivate the 
function.

If this function is selected, the minimum value for the 
alarm has to be adjusted.
Adjustment range: 0 ... 99.9 bar

 

Max Alarm:

If the maximum relative pressure is reached, the relay 
is energized,   appears in the display, the LED flashes 
green and an alarm message appears in the submenu 
“Reports”.

 

Î

Select “Yes” or “No” to activate or deactivate the 
function.

If this function is selected, the maximum value for the 
alarm has to be adjusted.

Signal 2

Adjust the parameters and values for the second sensor 
signal. The second signal of each sensor depends on the 
sensor type. Therefore, the following parameters and adjust-
ment values depend on the sensor type (flow rate for VFS, 
pressure for RPS, differential pressure for DPS)

Adjust the parameters referring to the flow rate (signal 2) 
if a VFS is used:

 

Unit:

 Select the unit of flow rate. 

A selection can be made between l/min, m³/h and 
gallon/h.

 

Offset:

 An offset can be carried out. The adjustment 

range depends on the previously selected unit. 

 

Min Alarm

:

If the minimum flow rate is reached, the relay is ener-
gized, 

 appears in the display, the LED flashes green 

and an alarm message appears in the submenu “Reports”.

on the previously selected unit.

 

Max Alarm:

If the maximum flow rate is reached, the relay is ener-
gized, 

 appears in the display, the LED flashes green 

and an alarm message appears in the submenu “Reports”.
