If, during measurement, the compressor is put out of operation the number
9990 will be displayed, i.e. the compressor is switched off and the energy loss
due to leakage could not be properly determined during said measurement. In
this case, too, the measurement process should be repeated at a later stage
while making sure that the compressor be switched off during
Start continuous measurement
Continuous leakage measurement will start immediately. Make sure
– that during the following days, at least for once during a time frame of
12 hours, no operational compressed air production takes place;
– that the compressor be set into the "ready" mode by means of the control
unit and that the green LED of the control be lit
In order to start continuous measurement:
1. Call up „Continuous Leakage Measurement" in the display"
(see "Continuous leakage measurement" on page 9.).
2. Press ENTER key
The number 9999 appears next to Lc. Continuous measurement will start
immediately and keep being carried out. After the twelve-hour time frame,
during which no operational production has taken place, has been exceed-
ed a sound measurement value is
The control system will always save the lowest value. A search for the lowest
value – as a background process – will be restarted once a week. This allows,
after expiry of another week, a higher value compared to the one of the pre-
vious week to be displayed if the measured minimum value has increased
during that period. Any potential increase of leakages in the compressed air
network will therefore also be possible to be determined.
Any power failures during measurement will not be indicated by a sequence
of digits because new values will be calculated every six hours and because
any such power failure during measurement will not prevent the values of the
subsequent measurement to be displayed
If changes are made to these target values, the value of P
held or brought outside any applicable minimum hysteresis range.
