4.5.3 Function "Filling"
Press and hold the "Filling" button for about 5 seconds until the yellow
LED is blinking. The filling process has been activated.
When the operating pressure has been reached, the yellow signal
lamp will go out and the filling process is turned off.
In case of a pressure drop due to pressure compensation processes,
the filling process can be reactivated to fill the interstitial space com-
pletely.
Holding this button down for more than 10 seconds will trigger the
alarm. The triggered alarm will go off shortly after letting go of the but-
ton.
4.5.4 Function "Testing the optical and audible alarm signal"
Press and hold the "mute" button (about 10 seconds). The alarm will
be triggered until the button is released.
This inquiry is only possible if the pressure in the system has exceed-
ed the "Alarm OFF" pressure.
4.5.5 Function "Tightness inquiry"
Press and hold the "mute" button until the signal lamp is blinking rap-
idly, then release it. The display (103) will show a tightness value and
the same value will be indicated by the "Alarm" signal lamp flashing.
10 seconds after displaying this value, the leak detector will return to
normal operation.
This inquiry can only be performed in operating mode "C". The leak
detector must have performed at least 1 automatic refilling interval in
normal operating conditions (i.e. without manual activation of the fill-
ing function) to achieve a valid statement.
For evaluation of the value displayed see Appendix 11.1.
