SERVICE MODE DETAILED DESCRIPTION
Technical Manual
n.37 Disable turbine contamination prevention system (n mode
= 0, 1)
This service mode can be used to disable the software controlled turbine contamination pre-
vention system. It is recommended to keep this mode turned on (1) at all s to guarantee max-
imum turbine hygiene.
Set this mode temporarily to 0 (zero) if you want to compare or demonstrate the difference in
turbine performance. This demonstration should be done with the turbine connected to an
instrument location not having a built in CP (contamination prevention) valve (no label close
to the IMUX quick connector).
The turbine contamination prevention system is based on a sophisticated software algorithm
that controls the turbine in such a way that the turbine head can never produce vacuum,
therefore minimizing the risk of contaminating the turbine or the turbine quick-connector.
n 38 Show internal water or air pressure (A H)
This service mode can be used to check the internal water and air pressures.
Checking the air pressure (An.nn bar; Annn kPa; Ann.n PSI)
Press the A-key to enter the air pressure measurement mode. The display shows the air
pressure either in bar, kPa or PSI (depending on the setting in service mode 17). The display
stabilizes within a few seconds. The static air pressure should be 5.5 bar (550 kPa).
Checking the water pressure (Hn.nn bar; Hnnn kPa; Hnn.n PSI)
Press the B-key to enter the water pressure measurement mode. The display shows the
water pressure either in bar, kPa or PSI (depending on the setting in service mode 17). The
display stabilizes within a few seconds. The static water pressure should be 2.5 to 2.8 bar
(250 to 280 kPa).
NOTE Please make sure that there is at least one water consuming instrument hose
connected before performing the water pressure measurement (a scaler, tur-
bine or micromotor hose). Leaving the water pressure measurement mode
causes the unit to turn off valves in the console, resulting in a small amount of
water (a few drops) flowing out from the IMUX. This behaviour is fully normal
and is due to the way the measurement is performed (using the spray water
line sensor).
