• Non-adherence to the operating instructions or technical data can lead to
personal injury and/or damage to property.
• In all applications check compliance of the product materials (→ chapter 12
Technical data) with the media to be measured.
• Use in gases at pressures > 25 bar only after contacting the manufacturer ifm.

Static and dynamic overpressures exceeding the indicated overload pressure are to be avoided by taking appropriate measures.
The indicated bursting pressure must not be exceeded. Even if the bursting pressure is exceeded only for a short time, the unit can be destroyed.
NOTE: Risk of injury!
Use in gases at pressures > 25 bar only after contacting the manufacturer ifm.
The units are supplied with an integrated damping device to comply with the
regulations for UL approval and to avoid any risk of injury in case of bursting when
bursting pressure is exceeded.
• When the damping device is removed the damping device can become unusable.
• When the damping device is removed the unit can no longer be used under UL
conditions,
If you have any questions, please contact ifm electronic’s sales specialists.

4.1 Processing of the measured signals
• The unit shows the current system pressure on its display.
• It generates 2 output signals according to the parameter setting.
OUT1
OUT2

switching signal for pressure limit values
analogue signal 4..20 mA / 0..10 V
4.2 Switching function
OUT1 changes its switching state if it is above or below the set switching limits
(SP1, rP1). The following switching functions can be selected:
• Hysteresis function / normally open: [OU1] = [Hno] (→ fig. 1).
• Hysteresis function / normally closed: [OU1] = [Hnc] (→ fig. 1).
First the set point (SP1) is set, then the reset point (rP1) at the requested distance.
• Window function / normally open: [OU1] = [Fno] (→ fig. 2).
• Window function / normally closed: [OU1] = [Fnc] (→ fig. 2).
The width of the window can be set by means of the distance between SP1 and
UK
rP1. SP1 = maximum value, rP1 = minimum value.

9 Parameter setting
During the parameter setting process the unit remains in the operating mode.
It continues its monitoring function with the existing parameters until parameter
setting has been terminated.
9.1 Parameter setting general
Each parameter setting requires 3 steps:
1
Selecting parameter
►► Press [Mode/Enter] until the requested parameter is displayed.
2
Setting the parameter value
►► Press [Set] and keep the buton
pressed.
>> Current setting value of the parameter bit flashes for 5 s.
>> After 5 s: Setting value is changed:
incremental by pressing briefly or
scrolling by holding pressed.
The numerical values are incremented continuously. If the value is to be reduced: Let
the display move to the maximum setting value. Then the cycle starts again at the
minimum setting value.
3 Acknowledge parameter value
►► Press [Mode/Enter] briefly.
>> The parameter is displayed again.
The new setting value is stored.
