Operation & Service
Heat-Up Time
Right when the device is turned on,
red-y
is ready for use. For the most precise measurements,
however,
red-y
is ready in 30 minutes (option of external feed). Before turning on, please be sure
that the wiring is correct and is installed according to the installation plan, and that the gas
connections are also mounted in accordance with the installation instructions of the manufacturer.
Zero Point Check
Without any special specifications for the installation position of the device, the zero point is aligned
at operating temperature and horizontal installation position before delivery. If the device is installed
vertically, a value can be read out at a zero flow rate according to operating pressure. During the
check, be completely sure that no gas is flowing. In the case of a shift in the zero point, please
contact your sales partner.
Service
With proper operation,
red-y
does not require any routine service at all. If the measurement value is
in a quality-relevant range (e.g. ISO 9001), we recommend a periodic check of calibration. The
interval depends strongly on use.
Cleaning in the Case of Contamination
Should there be suspicion of contamination (sudden deviation of measurement value in familiar
processes, visible traces in the piping, etc.), try flushing the device with a dry inert gas. Depending
on the contamination, it may be necessary to dismantle the device.
Tips
- Use only designated tools.
- Handle the device and individual components with extreme care.
- Ensure that the dismantling area is clean.
- The guarantee lapses at all events with the dismantling of the device.
- Never loosen a torx screw.
- Do not touch the electronic circuit board or electronic components under any circumstances.
- After the cleaning, you should have the device checked by your sales partner at the first
opportunity.
Dismantling Flow Module
- Disconnect the gas and electrical connections.
- On the inlet side, carefully unscrew the flow rectifier together with the flow divider.
With this design, there are no o-rings in this area. You can now clean the entire flow module
with a mild solution (e.g. IPA). Afterwards, ensure that the bored holes are absolutely clean,
dry and cleared.
