Avoid static and dynamic overpressure exceeding the specified 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. ATTENTION: Risk of injury! Pressure Equipment Directive (PED): The units comply with section 3, article (3) of the Directive 97/23/EC and are designed and manufactured for "non-superheated liquids"...
4 Function • The unit displays the current system pressure� • It generates output signals according to the operating mode and the parameter setting� • It moreover provides the process data via IO-Link� • The unit is laid out for fully bidirectional communication� So, the following options are possible: - Remote display: reading and display of the current system pressure�...
P = system pressure; HY = hysteresis; FE = window 4.3 IO-Link General information This unit has an IO-Link communication interface which requires an IO-Link- capable module (IO-Link master) for operation� The IO-Link interface enables direct access to the process and diagnostic data and provides the possibility to set the parameters of the unit during operation�...
5 Installation Before installing and removing the unit: Make sure that no pressure is applied to the system� ► Insert the unit in a process connection with a suitable thread� ► Tighten firmly� Tightening Torque 1/4-18 NPT threads: 2���3 turns after finger tightened� To ensure leak-free joints for NPT threads, sealants and lubricants com- monly used in the industry should be used�...
