Note: The numbers are not rounded off, but they are made invisible (also called a floor
function) The totalizer and the bar graph will not be effected by this setting and will
also work based on the real high resolution flow.

Set password
□ Enable password
To avoid the unauthorized changing of settings in the menu, it is possible to protect the
menu with a self-defined password. If you enable this option you first have to enter a 4-
digit numeric password to gain access to the menus. In this setting you can also define
that password. You can only activate the password after you have defined your own
personal password under “Set password”
If you forget or lose your password, please contact the factory at:
4.12.7. Battery auto off
To extend the battery life to the maximum we recommend that you set this menu so that,
when powered with a battery, the red-y compact 2 will switch off automatically after the
indicated number of minutes.
Please note that this menu has no effect if the unit is powered by USB or the external 24
Vdc. Once the unit is switched off it no longer totalizes the flow.
Note: When we supply the unit, the “auto power off” will be set to 15 minutes
4.12.8. Factory reset
If you activate the factory reset, all variables will be reset to the factory default (for
instance the password protection will be disabled). The continuous totalizer, however,
keeps its value. Only the resettable totalizer gets reset to zero. The reset takes about 30
seconds.
5. Maintenance
When operated properly and with the use of clean and dry gas, red-y compact devices
do not require any routine maintenance. There are no internal moving parts in the
measurement part of the device. However, we recommend that the calibration is
checked after 12 months. If your red-y compact is still within tolerance, this time
interval can be extended. The timing of the periodic check is the customer's
responsibility.
5.10. Cleaning to remove contamination
Depending on the type of contamination, on-site cleaning of the measuring or control
device may be possible. As a first step, we recommend flushing with N
2
or dry air. If it
is contaminated with liquids (ex. oil), pure methanol alcohol (100%) can be used. After
cleaning, rinse the red-y compact with the optional needle valve position fully open
with dry air or nitrogen for approximately 15 minutes to dry out all liquids.
Notes:
The warranty is null and void if the housing was removed.
Only use the proper tools.
Be careful when handling the device and the individual components.
