JDC Instruments SKYWATCH WWS Instructions For Use

GB US
This instrument was developed for protecting persons and properties that may be subject to strong winds. It consists of 2
parts:
1. A display unit of the wind force, with 4 programmable warning thresholds.
2. A multidirectional turbine (wind sensor) enabling measurement of the wind in the horizontal plane and in the vertical as
well (turbulence behind objects). The turbine sends its signal magnetically to a transducer located at the end of the cable
connected to the display. This transmission system simplifies the installation process.
The SKYWATCH WWS operates from two 1.5 V batteries of type LR6/AA/AM3 (sufficient for over 2 years without replacement)
and equally well from an external supply of 6 to 30 VDC (cigar lighter socket, mains power etc.). When an AC-DC adapter is
connected, the batteries are disconnected. If the power fails, the batteries automatically take over.
INSTALLATION
• Install the display housing with the fixing clamp, sheltered from the rain and from excessive humidity.
• Install the turbi ne in an open location and sufficiently far from any wall or any other obstacle to the wind, to ensure
greatest accuracy for the measurements.
• Connect the cable t
• Install the cable up to the turbine.
• Position the transducer on the end of the cable close to the impeller, and preferably perpendicular to its axis of rotation.
PARAMETERS SETTING
The following parameters can be modified:
- The 1 maximum threshold (Max1) for the alarm
st
- The 1 minimum threshold (Min1) for the alarm
st
- The 2 maximum threshold (Max2) for the alarm
nd
- The 2 minimum threshold (Min2) for the alarm
nd
- The units of windspeed
- The impeller model
- The sound level of the alarm
To modify the parameters, press the
