Capetti WSD12-VW Wireless Smart Datenlogger Schwings Aitenaufnehmer

(Vibrating Wires)

Description

The WSD12-VW is a datalogger with 4 input channels to acquire frequency and temperature on vibrating wires, with storage functionality of samples acquired.

Datalogger preset and use mode

Wireless Mode
No setup operation is needed. Typically the system is configured from factory so the datalogger is already associated to the system basestation. The datalogger is in STANDBY mode for which is necessary to start it with the TEST command (refers to chapter 3 – Wireless Installation).
Otherwise, in case the datalogger is in FACTORY RESET mode, that means it’s ready for connecting to an existing system, in order to associate it, make reference to the “WineCapManager” software manual. Is necessary to use the “WineCapManager” software on the PC connected to the basestation that will be coupled with the datalogger.

USB Datalogger Mode

• For this operation mode, stand-alone with data downloads through USB, the connection with the PC and the “WineCapManager” running on it is necessary in order to modify the datalogger’s operation mode.
• The sampling interval must be set with the datalogger in “STAND-ALONE” mode and automatically, the datalogger’s clock is aligned with the PC’s clock, in order to assure the temporal reference of the sample.
• Sampling operations start may be selected disconnecting the USB cable or giving the proper command with the magnetic key. (see chapter 4 – USB Logger Installation). More details on datalogger’s connection/disconnection through the USB cable are available on the manual.

On field transition from USB to Wireless datalogger
This transition is practicable in field, during the sampling period, using the wireless network association command. When the association is done, the datalogger becomes a wireless datalogger and, besides sending new measures to the basestation, starts a download process towards the same basestation of the measures acquired during the stand alone period.

Wireless datalogger user interface

• The user interface consists of a “virtual” button that can be activated using the WineCapKey and of a two-coloured led.
• To give a command, user must approach the WineCapKey to the datalogger’s sensible area and keep it in that position.; the following picture (Pic. 3) shows datalogger’s sensible points.

The following COMMAND table describes the available commands

|

STATUS

| Shows the device STATUS. As answer the led perform a flash sequence as reported in the “STATUS” table. If the device is performing the TEST ( refer to TEST

command ) this command stops it.

|

TEST

| Enter in TEST mode and transmits status and measurements every 5 seconds. If the device is in STANDBY mode or it is out of radio range, this command forces the connection procedure to the WSN and the return to the operative mode. The TEST stops after 120 seconds. During TEST the led continuously shows the STATUS to monitor the received radio signal quality.

CAUTION : Measures acquired during TEST phase are NOT saved.

|

ENROLL

| Association to the network: must be used when the device has not yet been included in a network, starts the entry and association procedure to the

basestation.

|

STANDBY

| Temporary device deactivation: the device is stopped. The sampling process and the radio are turned off losing the connection to the network. To reactivate, a TEST command is necessary. The STANDBY command must be given twice to confirm it: at the first sequence the led flashes alternating RED and GREEN lights, waiting for the second confirm sequence within 15 seconds. At the command

execution the led flashes as the STANDBY status ( refer to “STATUS” table ).

|

FACTORY RESET

| The device performs the memory deleting procedure and goes in STOP status. All samples, configuration and wireless network data associated are LOST. To reactivate the device a new association and configuration procedure is necessary ( ENROLL command ). Also in this case, the FACTORY RESET command must be given twice to confirm it. At the command execution the led flashes as the

“DATALOGGER NOT ASSOCIATED” status ( refer to “STATUS” table ).

|

LOGGER NO WSN

| As the previous command but performs only the WSN deleting procedure and disassociate from the basestation. The device enter in LOGGER STAND ALONE mode: data are kept and the sampling activity CONTINUES with previous setup. Command must be given with 2 sequences: 5 flashes and then 3 flashes. At the command execution wait for the device reboot. At the STATUS command, “LOGGER” will be the answer ( refer to “STATUS” table ). A new association ( ENROLL

command ) is possible to a new basestation.

Enrolling the datalogger

• Enroll the datalogger to the network referring to the “WineCapManager” software manual.
• In case the datalogger is already enrolled but in STANDBY status, a TEST command must be issued.

Installation procedure

• After installing the basestation in appropriate place in charge, (refer to the “WineCapManager User Manual”), be sure that the datalogger is enrolled to the basestation and activated.
• Head for the environment to be monitored. On the way, to check the quality of the radio coverage, use the “Field Measurer” function.
• This function is activated issuing the TEST command: position the WineCapKey in the spot indicated in Picture (Pic. 3) and wait for two AMBER flashes, then remove the WineCapKey from datalogger. The “Field Measurer” function lasts enabled for two minutes.
• To issue commands to the datalogger, place the WineCapKey where indicated.
• Once the WineCapKey is detected, the led periodically emits AMBER flashes with a 2 seconds cadence.
• For each flash, a different command is associated; to confirm the command the WineCapKey must be removed from the sensible area immediately after the number of flashes corresponding at the desired command. The TEST corresponds to the second pulse and activate the “Field Measurer” function.
• The datalogger will give back the radio signal quality through led flashes:

Picture 5 – Status table – Radio signal quality

• Optimize reception selecting the best position: small movements can help.
• If the signal is absent or insufficient at the install point, a WR12 router should be put between (refer to “WineCapManager User Manual). The router itself must be located in a position where the signal level is at least sufficient.
• The network will reconfigure itself automatically; the signal will be good again when the datalogger synchronizes with the router.
• The link will not be reconfigured until completely lost by the datalogger. Because of this, in some cases it could be necessary to force the operation. In such cases, put the datalogger in STANDBY mode, the run the TEST again (refer to “WineCapManager” User Manual).

NOTE: The display equipped datalogger (WD04T) is recommended, as reading the signal quality is made easier with this model.

Stand-alone USB datalogger installation

• Install the datalogger in appropriate place.
• If the sampling process has not yet been activated you can start it through the WineCapKey.
• Bring it closer to the sensitive point, wait for 2 flashes (TEST) and remove. The datalogger begins sampling according to your settings through your PC.
• Through the WineCapKey is possible to ask for the current status, bring it close to the datalogger for 1 flash (STATE) and remove it.

Shutting off/Reactivating the datalogger

• If the device is shut off and left unused for a long time, you can issue the STANDBY command. Its corresponds to the command number 4 and must be issued twice to confirm the operation.
• Position the WineCapKey in the spot indicated in Picture and wait for four AMBER flashes, then remove the WineCapKey from datalogger.
• Verify that the datalogger asks for confirmation of STANDBY command with alternate GREEN/RED flashing, then position again the WineCapKey and wait for four flashes again.
• The datalogger will confirm the STANDBY status lighting the RED led for 2 seconds twice. To reactivate the datalogger the TEST command must be issued.
