Air tank:
Check for proper operation of the check valve
on the air tank by disconnecting the pressure
hose from the valve.
Inspect the check valve once the
air tank is pressurised and the
compressor is off. No air may leak.
18.11. Check operation of solenoid
valve
(Fig. 23)
Valve functionality is checked using the
“Magnetic indicator” as follows: place it on the
valve coil and if the motors are active, the
indicator must turn, if not, the indicator does
not turn.
18.12. Checking the operation of
temperature sensor switching
(Fig.24)
This check is conducted using the LOGO!TDE
display where the instantaneous temperature
values are shown on the starting screen in
STOP mode. See Fig. 24
The check is based on a slight change in
temperature around the sensor, i.e. caused by
heating, or the temperature shown on the
display must also change. The B4 sensor is
not connected on uncovered versions and the
display shows N/A.
18.13. Check the function of pressure
sensor
Functionality is checked visually using the
TDE screen, which shows the compressed air
value. Changes in air usage must be reflected
in pressure changes on the display.
