3. Press the Enter key
 The number 9999 appears on the display and single measurement
starts in six hours.
 In twelve hours, the measurement value for the single measurement will
be displayed. The value will be stored until a new measurement is per-
formed.
 Should a power failure occur after the measurement has started, the
number 9980 appears on the display. In this case, the measurement
must be repeated at a later time.
 If the compressor is no longer on standby at any point during the
measurement, the number 9990 appears on the display. The compressor
has been switched off, meaning that the energy loss caused by leaks
cannot be recorded correctly. In this case, the measurement must also be
repeated at a later time. Measures must also be taken to prevent the
compressor from being switched off during the new measurement.
Starting Continuous Measurement
Continuous leakage measurement starts immediately. Ensure that:
– No compressed air is generated as a result of the normal functioning of the
system for a continuous period of at least 12 hours at some point over the
following days.
– The compressor has been set to standby / ready by the control and the
green LED on the control is lit.
To start continuous measurement manually:
1. Call up the main display of the control.
2. Press the Info key
 The "Continuous leakage measurement" display appears (see page 16).
3. Press the Enter key
 Lc 9999 appears on the display.
 Continuous measurement starts immediately.
 After the 12 hour period (during which no compressed air was gener-
ated as part of the normal functioning of the system) has passed, a valid
measurement value is displayed.
The control always stores the smallest value. The control searches for the
smallest value again (as a background process) on a weekly basis. This
means that after another week has passed, a higher value may be dis-
played compared to the previous week if the smallest measured value has
increased during this time. Thus, an increase in the number of leaks in the
compressed air network can also be recorded.
Power failures during a measurement are not displayed as a sequence of
digits, since new values are produced every six hours and a failure during
one measurement does not prevent values from being output for the follow-
ing measurement.
