A practical example of control unit setting is given below.
Let us assume that there is an installation where our objective is to decrease the pump flow when the wind is between 10 Km/h and 20 Km/h
and for winds faster than 20km/h, switching the unit off to prevent equipment damage and for safety reason.
For this, there is one anemometer and one control unit, that unit will be set following below control parameters:
-
Relay 1 will be disabled if wind is faster than 10km/h during 5 seconds of detection time.
-
Relay 1 will be activated again when wind is slower than 8 Km/h during a release time longer than 5 seconds.
-
Relay 2 will be disabled if wind is faster than 20 km/h during 5 seconds of detection time
-
Relay 2 will be activated again when wind is slower than 15 km/h during a release time longer than 5 seconds.
Note:
In this case, both relays Will be set as NC.
Control unit setting:
Relay 3
In this case, Relay 3 is not necessary, then, it will be set as out of order, thus both minimum and maximum configurable wind speed must be
disabled.
Procedure:
-
Press the key with a circle.
-
Press the arrows to reach
Relay 3
and press the circle´s key.
-
Press the arrows until
Definition working mode
and press the circle´s key.
-
Press the arrows to reach
Wind speed minimum
and press the circle´s key.
-
Press the arrows to reach
Operative
and press the circle´s key.
-
Press the arrows to reach
Return
and press the circle´s key.
-
Press the arrows to reach
Wind speed detection minimum
and press the circle´s key. Type 0.0 and validate.
-
Press the arrows to reach
Wind speed release minimum
and press the circle´s key. Type 0.1 and validate.
-
Press the arrows to reach
Definition working mode
and press the circle´s key.
-
Press the arrows to reach
Wind speed maximum
and press the circle´s key.
-
Press the arrows to reach
Non operative
and press the circle´s key.
-
Press the arrows to reach
Wind speed minimum
and press the circle´s key.
-
Press the arrows to reach
Non operative
and press the circle´s key.
