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 bur-
sting pressure is exceeded only for a short time, the unit can be destroyed�
NOTE: Risk of injury!
Function
4
Processing of the measured signals
4.1
The unit displays the current system pressure�
•
It generates 1 output signal according to the parameter setting�
•
OUT
analogue signal 4���20 mA (20���4 mA)
Pressure monitoring/ analogue function
4.2
The analogue signal can be set�
[OU2] defines whether the set measuring range is provided as a 4���20 mA
•
signal ([OU2] = [I]) or a 20���4 mA signal ([OU2] = [InEG])�
