INTRODUCTION
Safety Information
This manual contains information that must be observed in the interest of your safety and to avoid damage to assets. Please read this manual before installing and commissioning the device and keep the manual in an accessible location for all users. 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.
Hardware Features
The IWR range of Wireless Pressure & Temperature Receivers has been designed to receive the values from IWPT Wireless Pressure Transmitters and/or IWTT Wireless Temperature Transmitters and output the measured value as 4-20 mA or 1-5 V dc analog output signals. The IWR-1 has a single output. The IWR range of receiver units operates on the license-free 2.4 GHz band. Ranges of up to 500 m are possible using the standard transmitter and receiver units with the supplied antennas. The achieved ranges can be adversely affected by obstacles (particularly metals), walls, trees, vehicles, etc., in between the transmitter and receiver.
The receiver is powered by a DC voltage of between 12-32 V dc.
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.
IWR-1 RECEIVER SET-UP PROCEDURE
The IWR-1 receives data from an IWPT or IWTT wireless transmitter and produces a 4-20 mA or 1-5 V dc analog source output representing 0 – 100% of the range of the transmitter connected. It also has an alarm output that can be used as a high/low, loss of signal, or low battery alarm. As delivered the IWR-1 is configured to receive transmissions from an IWPT or IWTT wireless transmitter configured to channel 1.

|---|---|---|
| 4 | 0 | 0 |
| 2 | 0 | 1 |
| 6 | 1 | 0 |

Switches 7 and 8 configure the action of the Alarm Relay output. This can also be configured to the exact alarm values required using the USB port and the IWR-set software.

| Relay 1 switches OFF above 50% | 0 | 0 | |
|---|---|---|---|
| Relay 1 switches OFF above 75% | 0 | 1 | |
| Relay 1 switches OFF above 25% | 1 | 0 | |
| Relay 1 Configured via USB & IWR-Set | Software | 1 | 1 |
LED Indication
External LED 1 is used to indicate the status of the alarm relay. This is lit if the value transmitted is outside the alarm limit, the receiver has missed the number of transmissions configured above, or will flash if the transmitter has a low battery capacity. External LED 2 flashes when a valid transmission is received from a connected transmitter. The internal indicator LED3 is used to indicate the following alarm conditions: LED flashes 2 times: This indicates that the number of transmissions missed has exceeded the number set up by switches 5 & 6 above. LED flashes 3 times: This indicates that the transmitted value is outside the limits selected by switches 7 & 8 above. LED flashes 4 times: This indicates the transmitter has a low battery level.
Output Calibration and Analogue Output Scaling
The IWR-1 is factory calibrated for 4-20mA and 1-5V source outputs so that
if the transmits a zero or full-scale output the IWR-1 output will be within
its accuracy specifications. The output selector switch is used to select
either a 4-20mA or 1-5Vdc output. Push the switch SW1 to the left to select
4-20mA and to the right to select 1-5Vdc. It is possible to adjust the output
to match the equipment used to monitor the output or compensate for any zero
or span drift of the transmitter. This is achieved by using the pushbuttons
PB1 (DOWN) and PB2 (UP) and the internal LED as outlined here:
- Push both buttons at the same time then release to put the unit into zero-tare mode.
- LED will go amber, and the output will change to the zero value.
- Ensure there is no pressure/temperature applied to the connected transmitter and then use the DOWN and UP buttons to adjust the output to be 4mA or 1V
- If the led flashes amber this indicates that the connected transmitter’s zero value is not valid
- Push both buttons at the same time again and then release.
- LED will go red to indicate that the full-scale output will be adjusted. Inject the full-scale pressure or temperature range into the transmitting sensor using a Calibrator. If no Calibrator is available press both buttons again to exit the calibration saving only the zero tare. The LED will go amber for 0.5 seconds as the zero tare value is learned and saved to memory.
- If the full-scale transmitter range can be applied using the DOWN and UP buttons to adjust the output to be 20mA or 5V. When the output is correct push both buttons at the same time then release.
- If the LED flashes RED this indicates that the measured value is not close enough to the expected full-scale value to allow successful calibration.
- If full-scale calibration has been achieved the led will go amber for 0.5 seconds as calibration values are learned and saved to memory.
The saved values will now be used to produce the calibrated analog output. The analog output can be scaled to any part of the full-scale range of the transmitter connected.
For example, an IWTT with a P100 input sends a temperature back between -200°C & 800°C. By default, the 4-20 mA output will be at 4 mA at -200°C and 20 mA ay +800°C. the IWR-Set V2.1 software can be used to scale the 4-20 mA so that 4 mA is output at a temperature of 0°C and 20 mA is output at a temperature of +500°C. The setup procedure is intuitive once the IWR-SET software is opened on a PC and connected to the IWR receiver using a standard micro USB cable. If switches 5 & 6 are configured to switch the Alarm Relay if wireless transmissions are missed the analog output can also be set to go to a failsafe burnout output if no transmissions are received. If a 4-20 mA output is selected the output will go to 2.2 mA if Low Burnout is selected or 22.8 mA if High Burnout is selected. If No Action (the default setting) is selected the analog output will stay at the last valid value received from the connected transmitter.
TROUBLESHOOTING GUIDE
| Problem encountered | Possible Causes |
|---|---|
| LED2 doesn’t flash | The IWR receiver is not connected to a transmitter or the |
transmitter is out of range.
mA Output reads zero| The IWR receiver output is not wired correctly, check
the wiring and try again
Output from the IWR receiver isn’t equivalent to the transmitter range being
monitored| Check that the IWR receiver is linked to the correct transmitter by
pressing the push button inside the transmitter and checking that LED2 on the
receiver flashes when the transmitter button is pressed.
If the output still doesn’t agree with the reading, re-calibrate the unit as described above.
LED1 is solid ON| This indicates that the reading from the transmitter is
outside the limit selected or the receiver is out of range of the transmitter
and transmissions are not being received.
LED1 is flashing| This indicates that the battery inside the transmitter is
running low. Change the battery inside the transmitter taking care to exactly
follow the procedure outlined in the transmitter manual.
