If not:
5.
open solenoid valve (240): loosen 4 screws (247) from coil (246), lift off coil
(246) from valve housing (241). Pull out core (243) and check for free
movement and clean it, e.g. with compressed air. Check gasket (244).
Assemble valve again, but pay attention to correct seat of O-ring (242) in
valve housing (241). Try again to fog.
6.
Check hollow screw (250) with dosage nozzle and fog solution socket (57) for
free
passage.
Note:
The easiest way to test the solenoid valve (240) if unit is not running:
pull off the flexible pressure tube (228) from the pressure sensitive switch (214) and slip the
tube (314) - supplied with every unit - to fit the nipple of pressure sensitive switch (214) and
blow into it. Do not use decompressed air! Max. pressure allowed: 0,2 bar / 3 psi. If LED
(212) is alight, open and close respectively solenoid valve (214) by pressing button „green“
(210) and button „red“ (211) and a switching noise should be audible. If LED does not show,
the pressure sensitive switch (214) is defect. If , however, the LED shows green, but no
sound is audible, the battery voltage is too low (less than 4 volts) or the core (243) in the
solenoid valve (240) is stuck.
To dismantle solenoid valve (240) refer to paragraph 5.
Test solenoid valve (240) again as mentioned above.
Should above measures remain without success when checking the solenoid valve (240),
there might be a defect in the electronic control (213). Press red push button (211); LED
(212) should show green and after pressing the green push button (210), the switching noise
(on-off) of the switch in the relais must be audible. If not and voltage (> 4 volts) is sufficient,
replace electronic control (213).
Note:
The illumination of LED (212) when pressing the red push button (211) shows that some
voltage is available, but not what voltage. That means that LED (212) can show green, but
still the solenoid valve (240) does not function. Reason is that the voltage runs below 4 volts
when pressing the green button (210), which is noticeable by shortly going out or the bulb
shining darker. The batteries must be changed. It is, however, guaranteed that, if the valve
opens, it will close as well.
