  Do not touch the terminals while power is being supplied. Doing so may possibly result in electric shock Do not allow pieces of metal, wire clippings, or fine metallic shavings or filings to enter the product. Doing so may occasionally result in minor or moderate injury or in property damage due to electric shock, fire, or malfunction caused by internal short circulation..

  (3) In order to prevent inductive noise, wire the lines connected to the product separately from power lines carrying high voltages or currents. Do not wire in parallel with or in the same cable as power lines. Other measures for reducing noise include running lines along separate ducts and using shield lines.
• Page 7
  (10) Install an external switch or circuit breaker and label them clearly so that the operator can quickly turn OFF the power. (11) Ensure that the rated voltage is achieved no longer than 2 s after turning the power ON. When applying a voltage gradually, power supply may not be reset or output functions indeterminately.

  (1) Install the product horizontally. Display error has the risk of becoming larger than the standard because heat cannot be radiated. (2) When using a noise filter on the power supply, check that the filter is suitable for the supply voltage and current ratings, and then attach the noise filter as close as possible to the K3GN.

• Page 32
  Comparative output 2 Turning the power on causes inrush current to flow through the motor. But the K3GN does not produce superfluous output in response to the inrush current because it does not perform measuring operation for approx. one second after turn-on.

• Page 33: Monitoring The Quantity Of Dust

  The analog photoelectric sensor E3SA is used to detect the quantity of dust. A dust quantity of 0 to 1500 ppm corresponds to an E3SA output of 4 to 20 mA. The K3GN indicates the quantity of dust in units of ppm.

• Page 34
  2 Comparative output 1 turns on when the dust quantity reaches 800 ppm. When comparative output 1 turns on, the crusher power is reduced until the dust quantity decreases to within the specified range. Comparative output 2 turns on when an accident causes a sudden increase in dust quantity to 1000 ppm.

  The pressure sensor E8AA-M10 is used to detect the pressure in the tank. A pressure of 0 to 980 kPa corresponds to an E8AA-M10 output of 4 to 20 mA. The K3GN indicates the pressure in units of kPa to one decimal place.

• Page 111: Communication Protocols

  Comminations between the product and the host PC are implemented on a frame-by-frame basis. When the host PC sends a command frame to the product, the product returns to the host PC a response frame that corresponds to the command frame.

• Page 112: Data Format Structure

  PC are command frames and those from the product are response frames. The structure of these frames is shown below. In the following frame description, suffix H added to a numeric value, as in 02H, means the value is a hexadecimal number. And double quotation marks in which an alphanumeric value is enclosed, as in “00”, mean that the value is an ASCII…

• Page 114: Structure Of Command/Response Text

  The command/response text constitutes the main body of a command/response frame. The structure of the command/response text is as follows. The command text consists of MRC (Main Request Code) and SRC (Sub Request Command Text Code) followed by the required data.

• Page 115: Variable Area

  CHAPTER 7 COMMUNICATIONS 7.4 Variable Area A section of memory in the product that holds data to be transmitted is called the variable area. The variable area is used for reading of current process values or reading/writing of various parameters.

• Page 119: Setting Areas

  CHAPTER 7 COMMUNICATIONS 7.8 Setting Areas The K3GN series of products can assume two states that are refereed to as setting area 0 and setting area 1 in this manual. In setting area 0, the product is carrying out a measurement.

• Page 120: Commands And Responses

  This command reads the current process value. Use this command when the product is in setting area 0. (If the product is in setting area 1 when receiving the command, it returns a response with the “unknown” current value data).

• Page 121
  «00» «0001» Remote input value This command supplies an input value to the product that is used as a digital data display for PLC/PC. Use this command when the product is in setting area 0. (If the product is in setting area 1 when receiving the command, no change occurs on the main indicator as measurement is suspended).

  Likewise, even if the type of the OUT set value is “upper/lower”, an OUT set value can be written). If you want to write both OUT1 and OUT2 values at a time, use block access to the variable area. For details, refer to the tip shown in Section 7.10 Variable Area Map.

  Forced-zero lockout This command writes a protect level parameter. Use this command when the product is in setting area 0. If the product is in setting area 1 when receiving the command, it returns an error. Before issuing the command, use operation instructions to enable “writing” and to enter the protect level.

  It rewrites the value of the adjustment level parameter “communication writing”. If communication writing is disabled, operation instructions for parameter rewriting, forced-zero execution/forced-zero cancel and the like are rejected.
