Setti ng alarm values
The setup of each alarm consists of the level of the threshold, of the triggering edge, of the release
ti me aft er the alarm and the relay selecti on (Kit 2). If the threshold is set to OFF, briefl y pressing
goes to the setti ng up of the next alarm.
Threshold level •
The maximum threshold value depends on the selected unit but corresponds to 150 km/h.
Decrementi ng the value to obtain OFF will de-acti vate the alarm.
Triggering edge
•
The trigger edge determines whether the measurement must be higher (rising edge - max ) or
lower (falling edge - min ) than the threshold for the alarm to be triggered.
Durati on of acti vati on •
When an alarm is acti vated, it will be turned off when the alarm conditi ons are not met for x
seconds.
The ti mes to be selected are: 0 s, 10 s, … 60 s, -- (infi nite; the alarm will not be automati cally
cancelled).
Selecti on of relay
• (only Kit 2)
The desired relay can be selected depending on the alarm. It is possible for several alarms to operate the same relay.
Setti ng the unit
The measurement unit for wind speed can be selected from the following units: km/h, mph, knots, m/s and fps.
Adjusti ng the special parameters
The special parameters are the model of wind turbine and the acti vati on of the acousti c signal.
The turbine model •
The turbine model determines the turbine calibrati on used by the instrument. In general for the SKYWATCH AWS, the model
Pr1 should be selected. The other turbine models are used for specifi c installati ons.
Acousti c signal
•
The acousti c signal can be turned on or not (saving energy) for 1 minute when an alarm occurs.
Setti ng up the relays (only Kit 2)
The inacti ve state of each relay can be selected from no (normally open) and nc (normally closed).
