8.2 Explanation of the main menu
SP1/rP1*
Upper / lower limit for system pressure at which OUT1 switches�
OU1*
Output function for OUT1:
• Switching signal for the pressure limits: hysteresis function [H ��] or window
function [F ��], either normally open [� no] or normally closed [� nc]�
OU2
Output function for OUT2:
• Switching signal for the pressure limits: hysteresis function [H ��] or window
function [F ��], either normally open [� no] or normally closed [� nc]
(only available for 3-wire operation)�
• Analogue signal for the current system pressure: 4���20 mA [I],
20���4 mA [InEG]�
tCOF
Teach zero-point calibration�
tASP
Teach analogue start point for system pressure: set measured value at which
4 mA is provided (20 mA if [OU2] = [InEG])�
tAEP
Teach analogue end point for system pressure: set measured value at which
20 mA is provided (4 mA if [OU2] = [InEG])�
SP2/rP2*
Upper / lower limit for system pressure at which OUT2 switches�
