Contains FCC ID : W70MRF24J40MDME

Caution: To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance operation at closer than this distance is not recommended. The antenna used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. No other antenna may be used with this equipment other than the PCB antenna supplied with this equipment.

Please see the Certifications section for more information on RF Exposure Compliance

Hardware Features

• The IWTxT Wireless 4-20 mA Transmitters has been designed to provide an excitation voltage to any standard 4-20 mA transmitter, take a reading and transmit the value to one of the IWR range of receivers where the value can be outputted as either a 4-20 mA or 1-5 V dc signal, or to an IWR-PORT or IWR-USB receiver.
• The IWR-1 has a single output and the IWR-5 has five outputs, each of which can be linked to an IWTxT transmitter.
• The IWTxT current transformer transmitter works on the license-free 2.4 GHz band.
• Ranges of up to 500 m are possible using the standard transmitter and receiver unit with the optional 3dBi antenna giving a range of up to 750 m.
• The transmitter is powered by a 3.6 V lithium cell and care must be taken to insert the battery in the correct polarity.

UNPACKING

The instrument should be carefully inspected for signs of damage that may have occurred in transit. In the unlikely case that damage has been sustained, DO NOT use the instrument, but please retain all packaging for our inspection and contact your supplier immediately.

PRODUCT IDENTIFICATION LABEL

• The unit delivered should be carefully inspected to ensure it is suitable for the application required. Detailed information on the product is included in the identification label and the user manual.
• Please ensure, that the temperature range of the IWTxT is suitable for the intended application and that the IWTxT unit will not be subjected to temperatures and/or temperatures greater than those specified in this manual.

INSTALLING/CHANGING THE BATTERY

• A Lithium 3.6 V battery is included inside the IWTT transmitter. The battery may be changed at any time, but the correct polarity must be observed at all times! After the battery has been changed, the unit should be switched on using the SW3 push button and then SW1 should be pushed for 5s. This is to ensure the battery life count is reset correctly when a new battery is installed.
• The internal LED will flash 5 times to indicate this procedure has been carried out successfully.
• The battery life is determined by the rate the transmitter sends the Temperature value to the receiver, this update rate can be selected using Dip Switch 1 and the default value is 10s.
• A second set of batteries is used to provide the excitation supply to the external 4-20 mA transmitter. Polarity should again be observed when installing this battery pack.
• Please dispose of all batteries as specified by the legislator according to the Closed Substance Cycle and Waste Management Act or country regulations.

WARNING MAKE SURE THE CORRECT BATTERY POLARITY IS OBSERVED!
WARNING INCORRECT BATTERIES MAY DAMAGE THE UNIT USE ONLY THE SPECIFIED BATTERIES

SETTING UP THE IWTxT WIRELESS TRANSMITTER

The IWTxT instrument is shipped in a default configuration which allows the unit to connect with any default IWR receiver unit and transmit the measured 4-20 mA signal every 1 minute simply by switching the unit on using S2 on the internal circuit board.
If a different update rate is required, or a different network frequency channel is required these parameters can be selected using the 12-way DIP Switch as detailed below:

Dip Switches 1, 2, & 3 on the 12 -way Dip Switch selects the RF Network the IWTxT will transmit on. The default network for both the IWTxT transmitter and IWR receiver is network 1.

Switches 4, 5, & 6 select the Transmission rate of the unit. This effectively sets how often the 4-20 mA value is sent to the receiver. Note that selecting a transmission rate of below 1 minute substantially reduces the battery life.
At 1 and 5 second rate, a power save option is available (on by default) that changes the transmit time to every 30 seconds if the IWR is switched off or out of range for more than 3 minutes. This option can be changed using the IWT-SET program.

Switches 7 and 8 control the settling time of the 4 – 20 mA transmitter. This is the time that the transmitter is powered up from the transmitter supply before a reading is taken.

Switches 9,10,11,12 control the channel number

The IWTxT transmitter is now set up and ready to be used. Install the unit as required and switch the unit ON using SW2. Pushbutton switch S1 can be pushed to force the unit to transmit its current temperature and LED 1 will flash twice if the transmission has been received and acknowledged by an IWR receiver unit.
If the unit has successfully transmitted the output of the connected receiver unit will output a value reflecting the 4-20 mA level of the transmitter connected.

Connections

Battery life

The update rate and settling time affects how long the Excitation and Wireless batteries will last. The following gives the battery life in days with various configurations.

4-20 mA Transmitter Excitation Battery Life

2 off PP3 10.8 V Lithium Thionyl Chloride batteries in series (assume 1000 mAh capacity)

So, with a settling time of 0.5 seconds, and a sleep time of 120 seconds, the expected excitation battery life is 882 days.

Wireless Transmitter Battery Life

AA Lithium Thionyl Chloride battery (assume 1000 mAh capacity)

So, with a settling time of 0.5 seconds, and a sleep time of 120 seconds, the expected AA battery life is over 6 years.

Operation of the IWTxT 4-20 mA Wireless Transmitter

Remove the pull tab from the battery terminal.
Push and release the push button to wake the sensor and observe the LED.

• LED does a double green flash – successful send The button wakes the sensor up and the first green flash is seen. The sensor powers up the mA transmitter and waits for the settling time. The mA value is then read and transmitted to the IWR Receiver. If the data send is successful a second green flash is seen. It will now sleep for the sleep time, then wake and repeat this process.

• LED does a single green flash – failed to send
  The button wakes the sensor up, and the first green flash is seen. After the settling time and reading of the mA value, it sends the data to the IWR Receiver. The data send failed, so there was no second flash. It will now sleep for the sleep time, then wake and repeat this process.

• LED does one or two long red flashes followed by six short red flashes –successful join to network
  When the IWTxT is first switched it tried to join a network and was successful. It will now sleep for the update rate time, then wake, read the input, and send the data to the IWR Receiver.

• One or two long red flashes – failed to join the network
  When the IWTxT is first switched on it tried to join a network but in this case, it was unsuccessful. The IWTxT will now sleep for eight hours to conserve battery life before waking up and trying to join again. The push button can be used to wake it up to force it to try and join a network again.

Push button use

If the push-button is pushed and released quickly the sensor is woken from sleep to read the mA value. The led will flash green once or twice as described above.
If the push-button is pushed and held for 5 seconds the Z-Head can be forced to leave the network, it was joined to. It will then try and join again, indicated by long then short red flashes as described earlier. This action may be required if routers are used in the network.

TROUBLESHOOTING GUIDE

switch on using SW2. The battery is not installed correctly.

The battery needs replacing.

LED1 only flashes once when SW1 is pressed| IWR receiver not switched on.

IWR receiver is not set up for the same RF network.

IWR    receiver    not   within   range   of   the transmitter.

If an IWR-1 receiver is used, ensure that the transmitter is set to Tx Channel 1

Output from the IWR receiver isn’t equivalent to the 4-20mA transmitter being monitored| IWR receiver set up incorrectly, see IWR user manual for further details.

Check that the green external LED on the receiver is flashing when the transmitter push button is pressed as the receiver may be out of range.
