JDC Electronic SA Skywatch AWS - Manual

SKYWATCH® AWS
Air Warning System
Instructions for use
This instrument consists of 2 or 3 parts, depending on the options:
A display unit for the wind force, the percentage humidity and the temperature. •
The measurement system: •
Kit 1: • A TrH clip for temperature and humidity and a 15 m cable for use in measuring the wind.
Kit 2 & 4: • A 2 m cable for the temperature and humidity and a 15 m cable for use in measuring the wind.
Kit 3: • A single 5 m cable for measuring the wind, the humidity and the temperature.
SKYWATCH AWS Kit 4 has 4 relays that can be assigned to the different alarms.
The SKYWATCH AWS 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. 1.
Install the sensor with the aid of the aluminium bracket, in an open location and sufficiently far from any wall or any other 2.
obstacle to the wind, to ensure the greatest accuracy for the measurements. The bracket can be used in 2 orientations
depending on its position. (See pictures on www.jdc.ch)
Connect the cable to the housing:
3.
- Kit 1: Insert the cable connector into the 3-pole socket on the left and the TrH clip into the 5-pole socket on the right.
- Kit 2: Insert the plug of the 15 m cable into the 3-pole socket on the left and the plug of the 2 m cable into the 5-pole socket
on the right.
- Kit 3: Insert the plug of the 5 m cable into the 5-pole socket on the right.
- Kit 4: Insert the plug of the 15 m cable into the 3-pole socket on the left and the plug of the 2 m cable into the 4-pole socket
on the right.
Take care not to insert the 3-pole plug into the 5-pole socket as this risks damaging the equipment.
DISPLAY
Before an alarm:
The top line provides for the display of information about the wind (instantaneous and alarms 1-2).
The middle line provides for the display of information about the humidity
(instantaneous and alarms 3-4).
The bottom line provides for the display of information about the temperature
(instantaneous and alarms 5-6).
Pressing the button + (even alarms) or – (odd alarms) for 2 seconds will display the alarm thresholds. To
return to the current values wait for 10 seconds or press the button for 2 seconds.
Temperature and humidity are measured every 10 seconds. A short press of the
button will make a
measurement immediately.
During an alarm:
An alarm is activated 3 seconds after the threshold is passed for the wind, and 30 seconds for the temperature and humidity. The
alarms are activated and the symbol
> ALARM < flashes. When the alarm is activated, the LED for the corresponding line flashes.
The acoustic signal sounds for 1 minute. In the case where the active alarms are displayed on the same line, the display switches
between the alarms. To acknowledge the alarms, press the button for 2 seconds.
Remarks:
If the ambient temperature is positive, the display flashes during an alarm.
If the ambient temperature is between 0°C and -10°C, the display no longer flashes but if 2 alarms are active on the same line,
the display switches from one alarm to the other every 5 seconds.
If the ambient temperature is lower than -10°C, the display does not flash and the switching occurs every 10 seconds when 2
alarms are active.
After an alarm:
The
> ALARM < symbol of the corresponding line flashes but the displayed value is the instantaneous value.
To display the alarm value, press the + button (even alarms), or the – button (odd alarms).
The non-activated alarms are indicated by -- . After 10 seconds the system reverts to displaying the current values
