A PiPS (Plug-in Power Supply, art.nr.: 7.03.422) is available to power a single instrument and can be used instead of
the DB9 Loose-end cable as shown in the example above. Detailed information can be found in the manual PiPS
(9.17.055) which can be downloaded at the download section from the website: www.bronkhorst.com
7c. Bus / Digital RS485 operation
With digital operation over RS485 or Ethernet a bus-system with multiple instruments can be set up. If a separate
fieldbus-driver (e.g. DeviceNet™, EtherCAT®) is present (instrument top side), refer to the specific bus manual. For
RS485 operation over the 9-pin Sub-D connector (if installed) refer to the Instruction Manual EL-FLOW Prestige
Series (9.17.084).
8. Multi-functional switch operation
Using the 2 coloured LEDs and the switch on the EL-FLOW Prestige, several
actions can be monitored and started. The green LED is used for status
indication. The red LED is used for errors/warnings/messages. The switch
can be used to start several actions, such as auto-zero, restore factory
settings and bus-initialization actions, if applicable. See specific zero-
procedure below (10) or see ‘Instruction Manual EL-FLOW Prestige series’
(9.17.084) for more details.
The micro switch on top of the EL-FLOW Prestige can be operated with a thin, metal or hard plastic, pin.
For example the end of a paperclip.
9. Purging
In systems for use with corrosive or reactive fluids, purging for at least 30 minutes with a dry, inert gas
(like Nitrogen or Argon) is absolutely necessary before use. After use with corrosive or reactive fluids,
complete purging is also required before exposing the system to air.
Warm-up time
Let the EL-FLOW Prestige warm-up for at least 30 minutes for best accuracy.
10. Zeroing
The zero-point of each instrument is factory adjusted. If so required the zero point may be re-adjusted
over RS232, fieldbus or by means of using the micro switch. Procedure for zeroing by micro switch:
1. Warm-up, pressure up the system and fill the instrument according to the process conditions.
2. Make sure no flow is going through the instrument by closing valves near the instrument.
3. The setpoint must be zero.
4. Press micro switch and hold it. After a short time the red LED will go ON and OFF, then the green LED
will go ON. At that moment release the micro switch.
5. The zeroing procedure will start at that moment and the green LED will blink fast. The procedure will take
approx. 5 seconds.
6. When the indication is showing 0% signal and the green indication LED is burning continuously again,
then the zeroing action was successful.
Your EL-FLOW Prestige MFC is now ready for operation.
