Starting up the EL-PRESS in 9 steps
7
a. Analog/local operation
Connect the device to the power supply/readout unit using a cable with 9-pin D-sub connector. For controllers, the
setpoint is proportional to the pressure range. This principle also applies to digital operation.
b. Digital RS232 operation
Connecting the instrument with an RS232 cable to a Windows computer enables the use of the free Bronkhorst®
software for Windows, such as FlowDDE and FlowPlot.
Consult the
EL-PRESS
manual for more information.
c. Fieldbus operation
Connect the instrument according to the specific fieldbus standard. Refer to the appropriate fieldbus hook-up
document mentioned on page 2.

Multifunctional switch operation
Using the 2 LEDs and the switch on the
EL-PRESS
, several actions can be
monitored and started. The green LED is used for status indication. The red
LED is used for error and warning messages. The switch can be used to
execute several functions, such as bus initialization and restoring factory
settings. Consult the
EL-PRESS
manual (document no. 9.17.101) for details.

Purging
If the instrument will be used with corrosive or reactive media, purging with an inert gas (e.g. Nitrogen or Argon) for
at least 30 minutes is absolutely necessary before use. After use with these media, complete purging is also
required before exposing the system to air.
Warm-up time
For best performance of a
pressure controller
, let the instrument warm up for at least 30 minutes before
starting measurement and control (this can be done while purging)
For a
pressure meter
, the warm-up time is negligible
Your
EL-PRESS
is ready for operation.
