Application example: Oxygen control
In this example, the oxygen sensor O2S is connected to SENSOR 1 and the „normally opened“
solenoid valve (Type: MVO-M7-SC, Art. No.: 3020) is plugged into actuator plug OUT 1.
(„Normally open“ is selected here, that in case of a power shutdown the valve opens
automatically and the fish still get oxygen.)
The desired oxygen level should be over 95% and if 100% are reached, the addition of oxygen
shall be stopped. Go to the menu (MENU / Output Ports / Plug 1) and set:
Function: Sensor Control – a new submenu appears (when you go back in the
menu)
In the submenu „Sensor Control“ set:
o
Control Parameter: O2 % a.s.
o
Sensor Plug: 1
o
Start value: 95%
o
Stop value: 100%
o
Max. Duration: 00:00:00
o
Break Time: 00:00
In the submenu „Output signal“ set:
o
Polarity: Low Active (the output is switched off, when the O
2
concentration falls below 95% so that the [normally open] valve opens)
Now, all the settings are done and you can test the system, e.g. dipping the O2S sensor in
0-%-oxygen solution.
