IP66 warning device
Measure principle: The control unit that monitor continuously for possible wind overshooting respect a threshold preconfigured value. The function of the control unit is to command the closure of a relay contact each time is verified the above-mentioned condition.
Threshold configuration: The control unit allows to configure up to two thresholds, one for pre-alarm and another for alarm conditions. The thresholds can be configured across the related push-bottom and a regulation potentiometer to select the desired value.
Numeric display: The control unit includes a numeric 4 characters display for instantaneous wind velocity sensor data visualization, and thresholds value configuration.
Alarm condition recovery: Once the system is in alarm condition it can returns to the normal condition only when is pressed the push-bottom located in the bottom of the case and not only when the wind speed has decreased. Thus an operator must intervene and the alarm cannot go unnoticed.
Connectable equipment: It’s possible to connect external equipment for wind alarm condition dissemination (sirens, flashing lights etc) connecting it directly to the internal electrical clamps of both relays commands. Those contacts has a maximum capacity of 8 A@ 220Vac of resistive load.
