The EV03 is available in different versions. Some functions are preset based on the chosen configuration and cannot be changed afterwards via the display. The table shows the different options.
With the indirect control a pressure is applied to a volume using pilot valves. Several switch cycles are necessary for each control process. The pressure in these pilot volumes operates the valve (via a membrane). The outlet pressure is measured and any interference from the valve mechanics is electronically compensated.
In case of a power loss and thus a failure of the electrical control, mechanical pressure control is maintained by the pressure in the pilot volumes, even if air escapes from the main valve.
Therefore the indirectly controlled EPs are optimally suited for static conditions with only occasional set point changes.
The display shows the actual values and parameters directly on the device.
The following adjustment options are given:
Mount the EV03 with two cylinder head screws through the upper through-holes (20) or the through-holes on the sides (21) on a mounting plate (19).
