2.8

Micro switch operation

Using the two colored LEDs and the micro 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 and messages. The switch can be used to start

several actions, such as auto-zero, restoring factory settings and bus initialization

actions, if applicable.

See section

Adjusting zero point

for background information about and

instructions for zeroing.

See section

Micro switch functions

for a comprehensive description of the micro

switch functionality.

The micro switch on top of the

EL-FLOW® Prestige

can be operated with a thin, metal or hard plastic pin, e.g.the end of a

paperclip.

2.9

Powering up and powering down

It is recommended to turn on power before applying fluid pressure and to switch off power only after relieving fluid

pressure.

For best performance, allow the device to warm up and stabilize for at least 30 minutes before starting measurement

and/or control. This may be done with or without media flow.

When applying pressure, avoid pressure shocks and bring the fluid system gradually up to the level of the specified

operating conditions; open the fluid supply gently.

2.10

First use

In systems for use with corrosive or reactive media, purging for at least 30 minutes with a dry, inert gas (like Nitrogen or

Argon) is absolutely necessary before use. After use with corrosive, reactive or hazardous media (e.g. toxic or flammable),

purging is also necessary before the fluid system is exposed to air.

The very first time the instrument is used, adjusting the zero point is recommended. See

Adjusting zero point

for

background information and instructions.

2.11

Calibration

The EL-FLOW® Prestige is factory calibrated. Periodical inspection, recalibration or verification of the accuracy may be subject

to individual requirements of the end user.

Bronkhorst certifies that the instrument meets the rated accuracy. Calibration has been performed using measurement

standards traceable to the Dutch Metrology Institute (VSL).

Note that the calibration only applies to the primary measurement/control function of the instrument; secondary outputs

(like temperature and pressure) are outside the calibration scope.

2.12

Maintenance

The EL-FLOW® Prestige needs no regular maintenance if operated properly, with clean media, compatible with the wetted

materials, avoiding pressure and thermal shocks and vibrations. Units may be purged with a clean, dry and inert gas.

In case of severe contamination, cleaning the inside of the device may be required. After cleaning, recalibration of the

instrument is recommended.

Inexpertly servicing instruments can lead to serious personal injury and/or damage to the instrument or the system it is

used in. Servicing must therefore be performed by trained and qualified personnel. Contact your Bronkhorst representative

for information about cleaning and calibration. Bronkhorst has a trained staff available.
