Add extensions as required. Refer to the Rod Extension Requirements table. * The unit in as in Page 24 is improperly mounted.
Threaded Rod Antenna You can use 1.5” or 2” threaded process connections. There are three thread types: NPT, BSP, and G. 316 S.S.
Rod Assembly Teflon paste (supplied) optional extension 100mm (4”) 50mm (2”) Note: Ingress of water or process fluids into the connecting threads can cause reflections at the connection, appearing as false echoes. Installation Apply Teflon paste to threads and tighten slowly. Ensure that the rod sections mate securely with no gaps. Do not apply too much Teflon paste or parts will not mate securely. Do not use wrenches or pliers. Hand tight only. Sealant must have εr < 3.
Mounting: Rod Assembly Ideally, the standpipe should be as short as possible. If your application requires a standpipe that exceeds our recommended maximum lengths, consider using a waveguide and horn combination. If you create a new standpipe for the radar unit, ensure the weld seams are on the outside of the standpipe, not the inside. Ensure that there are no seams or lips on the inside of the standpipe or you may get erratic readings.
Mounting: Manhole Covers A manhole cover is typically a standpipe that is 24” in diameter or greater and has a cover. To provide the optimum signal conditions, locate the antenna off-center with respect to the cover, typically 100mm (4”) from the side of the manhole. Installation 100mm (4”) Mounting: Horn Antennas Usually, horns are mounted on short standpipes. The end of the horn should protrude a minimum of 10mm (0.5”) to avoid interference with the standpipe.
Mounting: Waveguide Antenna This option is recommended for products with εr lower than 3. The maximum range of this application is reduced to 10m (33 feet). See P655 on page 67.
Mounting: Stillpipe or Sidepipe An alternate to the waveguide antenna, this option is also used for products with an εr less than 3 or for extremely turbulent or vortex conditions. This mounting arrangement can also be used to provide optimum signal conditions on foaming materials. Suitable pipe diameters are 2” (50mm) to 10” (250mm). A rod antenna or a horn antenna may be used. Note: The measurement range is reduced to 13m (43’) for a 50mm (2”) stillpipe or 14.5m (47’) for an 80mm (3”) stillpipe.
Mounting: Horn with Waveguide Extensions In applications where the standpipe is too long and the diameter is too small (such as a standpipe that is 100mm (4”) in diameter and 460mm (18”) in length), the rod antenna is not suitable due to standpipe interference. In this case, use the waveguide/horn combination. Waveguide extensions are available in custom lengths. If the horn diameter is too large for the standpipe opening, you need to insert it from inside the vessel.
Mounting: Location Keep the 20° emission cone free of obstructions. Installation 20° Due to the polarization effect of the microwave signal related to the wall of the vessel, we recommend locating the IQ 300 a minimum of 30cm (1’) away from the sidewall for every 3m (10’) of vessel height. (rod antenna and 150mm [6”] horn antenna) Polarization Effect Mounting the unit too close to a wall may cause echoes to disappear at specific levels due to wave cancellation.

Start Up Page 44 IQ Radar 300 PL-611
Operation The IQ Radar 300 is a level measuring device for liquids and slurries. Using advanced pulse radar technology, the device calculates material level by emitting a series of radar pulses and then analyzing their reflections. The device consists of an enclosed electronic component mounted to a flanged antenna component. The electronic component generates a 5.8 GHz (U.S.A. 6.3 GHz) radar signal that is directed to the antenna, waveguide, or horn.
Operation Loss of Echo (LOE) A loss of echo occurs when the IQ 300 deems the calculated measurement unreliable, i.e. the confidence (P805) is less than the threshold (P804). Refer to Operation Troubleshooting on page 91 If the condition persists for a time beyond the limit as set by the fail-safe timer (P070), the Confidence icon changes from full to partial: to The response to LOE is set by P072. It determines whether the reading and mA output are immediately forced to the fail-safe default (P071).
Analog Output Programming When the unit is put into PROGRAM mode, the analog output level holds its prior value if the mA output function is not common output or if HART is not the communication protocol. [please verify] Run The analog output responds in the following manner: *reference value only. mA level limited by near blanking. 0 and 100% are percentage of full scale reading (m, cm, mm, ft, in).
Volume Operation To program the unit for volume, set: • • • operation (P001) to level 1 (see page 55) tank shape (P050) to a value other than 0 (see page 57) other volume parameters (P051 to P053) as required. To program the unit for ullage, set: • operation (P001) to space 2 (see page 55).
Application Examples These IQ Radar 300 applications examples can be used as setup references. The parameter value tables relate the values to the functions. Application Example: Asphalt in Storage Tank Note: The minimum distance from the antenna face to the target is limited by the near blanking, P800. Empty (P006) Asphalt build-up on the rod antenna does not affect performance.
Application Example: Horizontal Tank with Volume Note: The minimum distance from the antenna face to the target is limited by the near blanking, P800. Applications The application is to obtain a level measurement and corresponding 4-20 mA output proportional to material levels in a chemical tank. The bottom of the antenna flange is 3.5m from the tank bottom. The empty level is 0m (bottom) and the full level (span) is 3.0m from the bottom. The maximum rate of filling or emptying is about 0.1 m/min.
Application Example: Juice Batch Tank with Sanitary Horn Antenna Note: The minimum distance from the antenna face to the target is limited by the near blanking, P800. 4” sanitary horn mixer existing 4” tri-clamp connection Applications P006 P007 mixer Note: Sanitary Antenna Options: The one-piece antenna/process seal provides excellent mounting method, even on nonsanitary installations.
Application Example: Sliding Waveguide on Anaerobic Digesters Blanking, P800, and offset P652 are set at the factory. Check the device tag for specific values. Maximum level should be maintained at least .46m (18”) from the end of the horn. Applications horn The raised position is for installation and maintenance. The lowered position is for operation. Program the unit for operation in the lowered position.
Application Example: Stillpipe An alternate to the waveguide antenna, this option is also used for products with an εr or less than 3 or if extremely turbulent or vortex conditions exist. vent hole 100mm (4”) diameter Applications Note: For εr < 3, the lower 40cm of vessel level may not be measurable. This mounting arrangement can also be used to provide optimum signal conditions on foaming materials. Suitable pipe diameters are 50mm (2”) to 250mm (10”).
Note: Only set P837 if product is at least 2.5m (78”) away. If closer, leave P837 at 0 until such time the level drops below 2.5m (78”).

Communications: Modbus Register Map The memory map of the IQ-300 occupies the Modbus holding registers (R40,001 and up). A description of the types of data is on the following pages. The table legend is at the bottom of the table. This map is used when protocol is Modbus RTU slave or Modbus ASCII slave. The table legend is located at the end of the table. Register Map for Most Common Data Legend Type Start Data Type Description #R Read/Write Type The type of data held in the group of registers.
The measurement registers is 41,010. The available register Data Reading Volume Temperature Registers 41,010 41,020 41,030 and 41,031 Parameter P920 P924 P912 The reading is expressed as a percentage of full scale, multiplied by 100: Reading 0 5000 7564 20,000 Value 0.00% 50.00% 75.64% 200.00% Input/Output (R41,070 – R41,143) The IQ 300 has one mA output. mA Output (R41,110) The mA output is scaled from 0 to 2,000 (0 to 20mA multiplied by 100). Displayed in P911.
Format Word (R43,997) Format word is an unsigned integer that contains a value that represents a certain decimal offset. The decimal offset indicates how the remote system must interpret the integer value that is stored in the parameter access register. The following table shows how different parameter values can be shown based on a register value (integer) of 1234. Decimal 0 1 2 3 4 5 6 7 8 9 Offset 0 -1 -2 -3 -4 -5 +1 +2 +3 Percent Example 1,234 12,340 123,400 1,234,000 12,340,000 123,400,000 123.4 12.
This is a value between 0 and 40 which specifies the input or output indexed by the parameter. Examples (P920, primary index 1) 2. Write the secondary index value into R43,998. This is a value between 0 and 40 that specifies the secondary index on the parameter. This value is usually 0. 3. Write the desired format value into R43,997 [such as??]. 4. Read the value from the appropriate parameter register. Types of values are: • • • Numeric Values on page 85. Split Values on page 85.
Communications: Data Types The IQ Radar 300 parameters do not always use integers to hold values. For the convenience of the programmer, those values are converted to and from a 16-bit integer number. This section describes the conversion process. Numeric Values Numeric parameter values are the most common. For example, parameter P920 (Reading) returns a number that represents the current reading (either level or volume, depending on the IQ-300 configuration).
value1 = value / 256 value2 = remainder of value1 value3 = value2 x 256 yy = value3 – 128 It may simplify Parameter to notice: xx = (most significant byte of value) – 128 yy = (least significant byte of value) – 128 Text Messages Communications If a device parameter returns a text message, that message is converted to an integer and is then provided in the register.
Error Handling Modbus Responses When polled by a Modbus Master, a slave device will do one of the following: 1. Not reply. Which means that something went wrong with the transmission of the message. 2. Echo back the command with the correct response (see the Modbus specification for more details). This is the normal response. 3. Return an Exception Code. This reflects an error in the message.
If the host writes an invalid register (a non-existing parameter or a read only parameter), the value will be ignored and no error response will be made. However, the current value will not reflect the desired new value. • If the host writes a read only register, then the value will be ignored and no error response will be made. However, the current value will not reflect the desired new value. • If P000 is activated, then the value will be ignored and no error response will be made.
Troubleshooting Communication Troubleshooting Generally Check the following: 1. • • • There is power at the unit The LCD shows the relevant data The device can be programmed using the hand programmer 2. Check the wiring pin outs and verify that the connection is correct. 3. Verify that values in set-up parameters P770 to P773 match the settings in the computer communicating with the unit. 4. Check that the port you are using on the computer is correct.

Appendix III Single Parameter Access (SPA) This appendix provides advanced communication information to qualified personnel, enabling access to any parameter value in any available format. Built into the IQ Radar 300 is an advanced handshaking area used to read and write single registers to the unit. This section performs function similar to the Parameter Descriptions section on page 55, with two qualifiers: 1. Advanced section is more powerful and harder to program. 2.
Writing Parameters Complete the following to set parameters through Modbus: 1. 2. 3. Send the parameter, its primary index, and its secondary index (usually 0) to registers 40,090, 40,091, and 40,092. Write the value to registers 40,096 and 40,097. Write the desired format word to register 40,093 to enable the IQ-300 to interpret the value correctly.
If the numeric data type is set for integer and the value contains decimal places, they are ignored. In this situation, use the decimal offset to ensure that you have an integer value and then write your code to recognise and handle the decimal offset. Error Codes The error codes returned in the format area are 8-bit integers, found in the lowest 8 bits of the format word. This allows for 256 potential error codes. There are currently two error codes available in the IQ 300.
