Termination box, if long ground

cables need to be terminatedoutside the box

Additional guy wire set for

DKP12 in installations at sites

with heavy winds

Obstruction light


13/18

Periodic maintenance

Please check the periodic maintenance for the

sensors in the sensor specific manuals

Obstruction light; Check that the LEDs in the light

are OK. (The more LEDs are inoperative, the lower

is the intensity of the light)

Battery back up: Disconnect the voltage supply tothe battery charger and check that the back up

time is according to product specification /

customer requirement. The back up time for with a

new battery is very long; app 3 days for 6 Ah

option and 1 - 2 weeks for 48 Ah option.

Clean the surface of the solar panel and measure

with multi meter that the unit is charging

Trouble shootingProblem Probable cause Remedy

AWSS301 is sendingslashes(////) instead of oneor more of the sensorreadings.

Please note that slashesare sent if thecorresponding sensor isnot connected to theAWSS301.

The sensor wireconnections / sensorwires are defective.

Sensor(s) is(are)defettive

The sensor is missing.QML101 logger isexpecting all optionalsensors to beconnected. Slashesare OK for thesensors that are not

included in theAWSS301.

Check the terminal connections in the AWSSBOX301. Check that the wires are according tothe delivery documentation. If OK, check thecondition of the wires.

If above OK, the most probable cause of themissing data is a faulty sensor. In this case thesensor should be replaced.

AWSS301 is not sendinganything (nothing is seenon the screen).

Press and keep down the reset button for a fewseconds. AWSS301 will restart and display:"Using blank configuration". After this, theproper configuration must be downloaded!Type openand press enter. The command hasto be typed exactly right before it can beexecuted.

The terminalconnection is notopen.

Correct PC port and AWSS301 com portsettings and check the cable connection.

AWSS301 will not open forcommands.

AWSS301 is notreceiving power.

Check connections and power supply.

The Setup file doesnot exist in Cfgdirectory.

Copy or load the file to the correct directoryAfter reset, AWSS301displays "!Erroneous setupfile".

Setup file is not

executable.

Type "chmod Filenamerwx".

Configuration file

AWSS301 is always delivered with factory

installed configuration file

The used configuration file depends on the

selected communication option and pressure

optionIf wrong file is installed, the AWSS301 does not

perform any measurements or transmit data

In the following slides there is described how theconfiguration file is loaded


16/18

Loading the configuration file

Start HyperTerminal

(Win 95/NT).

Start > Programs > Accessories >

HyperTerminal> HyperTerminal(hypertrm.exe)

Give name

"AWSS301" to the

new connection.Click OK.

The Phone Number

dialog will open.

For Connect Using,

choose Direct to

Com 1(or another

Com port if you arenot using port 1).

Click OK.

The COM

Propertiesdialog

will open. Make the

settings according tothe picture.

Click OKand the

connection to

AWSS301 is set up.

After typing open,

you can start givingcommands to

AWSS301.

To be able to transfer

files to and from

AWSS301, you need to

choose the correct

transfer protocol:

ZModem.

When loading a new setup file to AWSS301 you must first delete

the old file: ("default" denotes the name of the setup file)

cd Cfg

del default

After that, give command zr

Choose Send File from Transfer menu. Choose Zmodem for

protocol and click Sendto load the setup into AWSS301.

9901-045

Make the setup executable:

chmod default rwx

Reset AWSS301 by giving command reset

When retrieving a log file from AWSS301, choose Receive file

from the Transfer menu. Choose Zmodem for protocol. Choose

also the directory where the retrieved file is to be stored.
