* in case of static overpressure
MPa = bar ÷ 10 / kPa = bar × 100
Static and dynamic overpressures exceeding the indicated overload pres-
sure 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 destro-
yed� NOTE: Risk of injury!
Pressure Equipment Directive (PED): The units comply with section 3, ar-
ticle (3) of the Directive 97/23/EC and are designed and manufactured
for media of fluid group 2 (stable gases and non-superheated liquids) in
accordance with the sound engineering practice�
4 Function
4.1 Evaluation
• The unit shows the current system pressure on its display�
• It generates 2 output signals according to the parameter setting�
OUT1
• switching signal for pressure limit values�
OUT2
• switching signal for pressure limit values�
• analogue signal for pressure (4���20 mA or 0���10V)�
