    SECTION 3. – Case Schematics. The IN-RTB has a 2 x 6-digit, 14-segment alphanumeric LED display, five front-panel buttons and five set-point annunciator LED’s (BCH SP (SP1), SP2-5). Fig 1 - Front view:...
  • Page 5 200Hz: Ideal for mechanical contacts 20kHz: Suitable for a noisy signal B - Mode Counter: ALWAYS use this setting Frequency: Not used for IN-RTB C - Input signal Logic: NPN, PNP, namur, TTL & pushbuttons Mag Pickup: Tacho D - Load Sink: NPN, TTL &...
  • Page 6 5.2 – Wire your IF11 analogue input module (when fitted): Refer to 3.2J Make sure that you have completed Section 4 before you begin wiring your input module. Once you have adjusted your Jumper settings as needed (see Section 4) and replaced the plastic backing plate, wire your input module as shown in the appropriate diagram: NPN open collector output with proximity switch: Active sensor signal: 0V.

  • Page 7: Section 6. - Setup & Calibration

    5.3 – Wire your relays (if fitted): Refer to 3.2G Wire your relays as per the diagram. IN-RTB relays can be programmed to operate within the total span range of the controller. If you do not have any relays fitted, step 5.3 is skipped.

  • Page 8: _ _ Calibration Method

    _ _ _ CALIBRATION METHOD scrolls across the bottom row and the current selection appears in the top row. Use the  and  buttons to select K FCTR (K Factor) or PULSES, and then press P . K FCTR - Select this option for fast, accurate calibration using the sensor manufacturer’s K factor value. PULSES - This option is ideal for applications where the flow sensor’s K factor value is not known.
  • Page 9 6.3 – Totaliser setup: The totaliser can be reset from the rear function pins (see 6.6). _ _ _ TOTALISER SETUP scrolls across the bottom row and SKIP appears in the top row. Press P to skip to 6.4, or the  button and then P to ENTER totaliser setup. _ _ _ DECIMAL POINT POSITION scrolls across the bottom row and the currently selected decimal point position appears in the top row.
  • Page 10 _ _ _ USER INPUT 2 scrolls across the bottom row and the currently selected User 2 pin function appears in the top row. Use the  and  buttons to select a function from the list, and then press P to confirm. This specifies the operation to be executed when the User 2 input pin at the rear of the meter is connected to the common pin (Section 5.6).

  • Page 11: _ _ Serial Address

    If you selected ENTER in 6.7E: _ _ _ CAL LOW ANALOG OUTPUT scrolls across the bottom row and a calibration number appears in the top row. Using the  and   buttons, calibrate your low analogue output as required. Then press P . The display value is shown in internal units (mA).

  • Page 12: Section 7. - Set-Point Setup

    MODBUS REGISTERS - These are all holding registers and should be accessed via function codes 3 and 6. Register addresses are displayed in the Modicon™ addressing format. i.e. Register 65=40065 (subtract 1 for direct addressing). 8-BIT UNSIGNED 24-BIT SIGNED (2x16-bit) Baudrate 48207 42509...
  • Page 13 _ _ _ TRACK BATCH SP scrolls across the bottom row and the last tracking setting appears in the top row. Using the  and  buttons, select OFF or ON. Then press P . Setting this option to ON will cause the selected set-point to track the set-point value of the batch set-point. The value of the tracking set-point will then become an offset value, which is effectively added to the value of the batch set-point.
  • Page 14 _ _ _ MAKE DELAY scrolls across the bottom row and the current selection appears in the top row. Adjust using the  and  buttons, and then press P . This defines the delay between set-point activation and when the relay turns on. This value is in tenths of a second.
  • Page 15 During the next batch, the effective BCH SP value is modified to include the calculated Correction Offset value, in an attempt to compensate for errors. (Correction Offset cannot be greater than 50% of the set-point value). If you selected OFF in 7.2S: Skip step 7.2T.

  • Page 16: Section 10. - Reset Pin Numbers

    This function is useful for feeding volume information to other equipment. The length of the pulse can be adjusted in 0.1 second increments (7.2F) to suit the requirements of externally connected devices. www.intech.co.nz Christchurch Ph: +64 3 343 0646 Auckland Ph: 09 827 1930 Email: sales@intech.co.nz IN-RTB 031115...
