Function
Via the suction line, the vacuum pump installed in the product generates a
vacuum in the interstitial space of the tank (vacuum range). The pressure
switch measures the vacuum in the interstitial space via the measuring line
and keeps it at a constant level together with the vacuum pump.
If a leak occurs in the tank's wall or in the leak protection lining (in the inner
or outer wall of the tank) either above or below the level of the stored liquid
or the ground water, and if this leak is greater than the suction capacity of the
vacuum pump, the vacuum will drop. When the alarm threshold for the
switching point is reached, the red alarm lamp and the audible alarm are acti-
vated and the relay is energised. The audible alarm can be switched off by
pressing the Off key.
