4.1.7
Solenoid valve status (ref. O2 and O3
)
After perceiving the signal from the sonar, and after the delay time set a priori (see
paragraph 4.6), the computer will activate the outputs for the corresponding solenoid
valves: that on the left for the left sonar and that on the right for the right sonar.
The operating status of the solenoid valves is shown on the display by two other pairs
of vertical segments (ref. O2 and O3) in the innermost part of the display.
These bars will remain on for as long as the solenoid valves will be active.
4.1.8
Working hours
The working hours appear just after the start-up test and remain on the display for a
few seconds.
The count of the working hours is activated 5 MINUTES after the first opening of one
or both solenoid valves; it is then deactivated when there are no more solenoid valve
activations for at least 5 MINUTES.
4.2
IZQD & DCHA auto/man keys
At any time, the solenoid valves can be switched (one at a time) from the automatic
operating status to the manual operating status.
Simply press one of the two special keys (ref. B and N) and the solenoid valves will
switch to the operating mode opposed to that in which they were working previously.
4.3
S.V. IZQD & DCHA start/stop keys
At any time, the solenoid valves can be stopped or restarted.
Pressing one of the two special keys (ref. D and I) will stop the corresponding solenoid
valve if it was running, or start it if it was already stopped.
N.B. If the LED included in the keys (ref. D and I) is on, this means "STOP" and the
solenoid valve must be de-energised. If the LED is off, the opposite occurs.
4.4
General S.V. auto/man key
This key (ref. G) allows the operating status of the solenoid valves to be switched from
automatic to manual mode simultaneously.
By pressing the "AUTO/MAN GENERAL" key, the operating status of the solenoid
valves will follow the progress of the LED indicator on the key itself.
That is, the green LED of the ON key (ref. G), means automatic operation of both
sections.
If, for example, the two sections were to work opposite each other, both will work in
automatic mode.
