Instruction book
The condensate enters the electronic water drain via inlet (1) and accumulates in collector (6). A
capacitive sensor (5) continuously measures the liquid level.
The pilot valve (3) is activated as soon as the collector is filled up to a certain level. Diaphragm
(4) opens outlet (8), discharging the condensate.
When the collector has been emptied, the outlet closes quickly without wasting compressed air.
When the controller registers a malfunction, the red alarm LED on the control panel of the
electronic water drain starts flashing, a warning appears on the display of the regulator and the
electronic drain valve will automatically change to the alarm mode, opening and closing the valve
according to a sequence as shown below . This condition continues until the fault is remedied. If
the fault is not remedied automatically, maintenance is required.
Testing the Electronic water drain
Briefly press the TEST button and check that the valve opens for condensate discharge.
Checking the alarm signal
• Press and hold the test button for at least 1 minute.
• Check that the alarm LED flashes.
