Avoid static and dynamic overpressure exceeding the given overload
pressure 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
may be destroyed. NOTE: Risk of injury!
Use in gases at pressures > 25 bar only after contacting the manufacturer
ifm�
Cannot be used for oils�
4 Function
4.1 Communication, parameter setting, evaluation
• The unit displays the current system pressure.
• It generates 2 output signals according to the parameter setting�
OUT1 • Switching signal for process value; IO-Link�
OUT2
2 options
• Switching signal for process value�
• Diagnostic signal (output 2 is inactive in case of a fault)�
• The following functions are available via IO-Link (OUT1):
reading the current process value, changing the parameters and transferring
them to other units of the same type using the FDT service program ifm Contai -
ner or other parameter setting tools with IO-Link capability�
The program library of the available DTM objects and the IO Device Descripti -
on (IODD) are available at www.ifm.com → Service → Download.
4.2 Switching function
OUTx changes its switching state if it is above or below the set switching limits
(SPx, rPx). The following switching functions can be selected:
• Hysteresis function / normally open: [OUx] = [Hno] (→ fig. 1).
• Hysteresis function / normally closed: [OUx] = [Hnc] (→ fig. 1).
First the set point (SPx) is set, then the reset point (rPx) with the requested diffe-
rence�
• Window function / normally open: [OUx] = [Fno] (→ fig. 2).
• Window function / normally closed: [OUx] = [Fnc] (→ fig. 2).
