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 Wireless Pressure & 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 and the IWR-5 has five outputs, each of which can be linked to an individual transmitter. The IWR range of receiver units operates on the license-free 2.4GHz frequency 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 12-32 V dc. WIRELESS PRESSURE & TEMPERATURE

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-5 Receiver set up procedure

The IWR-5 receives data from up to 5 off wireless pressure or temperature transmitters and produces 4-20 mA or 1-5 V dc analog outputs representing 0 – 100% of each of the wireless transmitters 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-5 is configured to receive transmissions from IWPT and IWTT wireless pressure transmitters configured from channel 1 to channel 5. Connections and Configuration Switches

Dipswitch Configuration
The 8-way Dipswitch 1 is used to configure the basic functionality of the IWR-5 The RF network code must be the same as the IWPT units to be used with the receiver unit. Switches 1, 2, 3 & 4 select the network code as below

• RF NETWORK 1 2 3 4
  • 1 0 0 0 0
  • 2 0 0 0 1
  • 3 0 0 1 0
  • 4 0 0 1 1
  • 5 0 1 0 0
  • 6 0 1 0 1
  • 7 0 1 1 0
  • 8 0 1 1 1
  • 9 1 0 0 0
  • 10 1 0 0 1
  • 11 1 0 1 0
  • 12 1 0 1 1
  • 13 1 1 0 0
  • 14 1 1 0 1
  • 15 1 1 1 0
  • 16 1 1 1 1

Switch 5 and 6 select the number of transmissions that are missed before the Alarm relay output switches to the alarm condition.

Missed Transmissions 5 6

• 4 0 0
• 2 0 1
• 6 1 0
• No Alarm 1 1

Switch 7 and 8 Configure the action of the Alarm Relay output. This can also be configured to exact alarm values using the USB port and the IWR-Set software.

Relay Action 7 8

• Relay 1 switches OFF any I/P above 50% 0 0
• Relay 1 switches OFF any I/P above 75% 0 1
• Relay 1 switches OFF any I/P above 25% 1 0
• Relay 1 Configured via USB & IWR-Set software 1 1

LED 6 is used to indicate the status of the alarm relay. This is lit if any of the values transmitted are outside the alarm limit, the receiver has missed the number of transmissions configured above, or flashes if the transmitter has a low battery capacity. LED 7 flashes when a valid transmission is received from any connected transmitter. There is also an indicator LED for each output channel of the IWR-5. These are used to indicate the following alarm conditions for each channel:

• 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 value for that channel is outside the limits selected by switches 7 & 8 above.
• LED Flashes 4 times: This indicates the transmitter linked to this channel has a low battery level.

Output Calibration
The IWR-5 is factory calibrated for 4-20 mA and 1-5 V source outputs so that if a sensor transmits a zero or full-scale output the IWR-5’s output for that channel will be within its accuracy specifications. The output selector switches are used to select either 4-20 mA & 1-5 V dc for each channel. Push the switch SW1 to the left to select 4-20mA and to the right to select 1-5 V dc
It is possible to adjust the outputs to match the equipment used to monitor the output or to compensate for any zero or span drift of the transmitters. This is achieved by using the pushbuttons PB1 (DOWN) and PB2 (UP) and the internal LEDs as outlined here:

• Push both buttons at the same time then release to put the unit into zero tare mode starting with Channel 1.
• LED1 will go amber, and output one will change to the zero value.
• Ensure there is no pressure or temperature applied to the connected transmitter and then use the DOWN and UP buttons to adjust the output to be 4 mA or 1 V
• If the LED flashes amber this indicates that the connected transmitter zero value is not valid.
• Push both buttons at the same time again and then release.
• LED1 will go red to indicate that the full-scale output will be adjusted. Inject the full-scale pressure or temperature range into the sensor using a Calibrator. If no Calibrator is available press both buttons again to exit the calibration mode saving only the zero tare value. The LED will go amber for 0.5 seconds as the zero tare value is learned and saved to memory.
• If the full-scale pressure can be applied using the DOWN (PB1) and UP (PB2) buttons to adjust the output to be 20 mA or 5 V. When the output is correct push both buttons at the same time and then release.
• If LED1 flashes RED this indicates that the measured value is not close enough to the full-scale value expected to allow calibration to be achieved.
• If full-scale calibration has been achieved LED1 will go amber for 0.5 seconds as calibration values are learned and saved to memory.
• To cycle which channel is being calibrated push the UP or DOWN buttons until the LED linked to the channel to be calibrated is lit. Repeat the above using the appropriate LED for the channel selected.

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

transmitters are out of range.
Any mA or Voltage Output channel reads zero| The IWR receiver output is not wired correctly, check the wiring and try again. If wiring is OK check the 4-20mA or 1-5 V dc selector switch is in the right position.
Output from any IWR receiver channel isn’t equivalent to the pressure or temperature being monitored by the appropriate transmitter.| Check that the IWR receiver is linked to the transmitter in question by pressing the push button inside the transmitter and checking that LED 7 on the receiver flashes when the transmitter button is pressed.
As above| Check that the transmitter is set to the correct channel number using the internal DIP switch.
LED 6 Remains Permanently Lit| One of the transmitters is sending a value that is outside the alarm conditions or the receiver is out of range of one of the transmitters or one of the transmitters is switched OFF.

The internal channel LEDs can be used to ascertain the

channel initiating the alarm and the type of alarm.

LED 6 is flashing| This indicates that the battery inside the transmitter is running low. Change the battery inside the transmitter taking care to reset the battery level using the procedure outlined in the transmitter manual.

The internal LEDs can be used to ascertain the channel

initiating the low battery alarm.
