Check if system piping is clean
For reliable operation, always make sure the fluid stream is clean.
Use filters to ensure a moisture, oil and particle free gas stream (recommended pore-size: 5 µm).
If back flow can occur, the use of a downstream filter and a check valve is also recommended. Select a suitable
filter size, to avoid a too high pressure drop.

Mounting/installing
P-500/600/700 instruments
: install the instrument in the line in accordance with the flow arrow on the
instrument body.
P-800 instruments
: install the fluidic connections in accordance with the inscriptions on the instrument body
(IN, OUT, RELIEF)
Forward pressure control (P-600)
Back pressure control (P-700)
Process Pressure Controller (P-800)
For high flow rates, installing the pressure meter in a separate branch is
strongly recommended (using a T-piece fitting).
Tighten the fluidic connections according to the instructions of the supplier of the fittings. The use of Swagelok
RS-type stainless steel adapters and Bronkhorst® elastomer O-rings is recommended.
Avoid installation in close proximity of mechanic vibration and/or heat sources.

Leak check
Check the system for leaks before applying (fluid) pressure, especially if toxic, explosive or other dangerous fluids
are used.
6
Electrical connection
Electrical connections must be made with standard cables or according to the applicable hook-up diagram (see
page 2).
EL-PRESS
instruments are powered with +15…24 Vdc.
A. Analog connection
B. Digital RS232 connection powered by plug in
power supply
C. Fieldbus (e.g. DeviceNet™)
Never
power the instrument simultaneously from
two different power sources
(e.g. fieldbus connection and
Plug-in Power Supply). Doing so will damage the printed circuit board irreparably.
