  • Page 3: Safety Precautions

    SAFETY PRECAUTIONS (Read these precautions before using this product.) Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. The precautions given in this manual are concerned with this product only. For the safety precautions of the programmable controller system, refer to the MELSEC iQ-R Module Configuration Manual.
  • Page 4 [Design Precautions] WARNING ● Configure safety circuits external to the programmable controller to ensure that the entire system operates safely even when a fault occurs in the external power supply or the programmable controller. Failure to do so may result in an accident due to an incorrect output or malfunction. (1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured external to the programmable controller.
  • Page 5 [Design Precautions] WARNING ● When connecting an external device with a CPU module or intelligent function module to modify data of a running programmable controller, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other forms of control (such as program modification, parameter change, forced output, or operating status change) of a running programmable controller, read the relevant manuals carefully and ensure that the operation is safe before proceeding.
  • Page 6 [Design Precautions] CAUTION ● Do not install the control lines or communication cables together with the main circuit lines or power cables. Doing so may result in malfunction due to electromagnetic interference. Keep a distance of 100mm or more between those cables. ●...
  • Page 7 [Installation Precautions] CAUTION ● Use the programmable controller in an environment that meets the general specifications in the Safety Guidelines included with the base unit. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product. ●...
  • Page 8 [Wiring Precautions] CAUTION ● Individually ground the FG and LG terminals of the programmable controller with a ground resistance of 100 ohms or less. Failure to do so may result in electric shock or malfunction. ● Use applicable solderless terminals and tighten them within the specified torque range. If any spade solderless terminal is used, it may be disconnected when the terminal screw comes loose, resulting in failure.
  • Page 9 [Startup and Maintenance Precautions] WARNING ● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction. ● Correctly connect the battery connector. Do not charge, disassemble, heat, short-circuit, solder, or throw the battery into the fire. Also, do not expose it to liquid or strong shock. Doing so will cause the battery to produce heat, explode, ignite, or leak, resulting in injury and fire.
  • Page 10 [Startup and Maintenance Precautions] CAUTION ● When connecting an external device with a CPU module or intelligent function module to modify data of a running programmable controller, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other forms of control (such as program modification, parameter change, forced output, or operating status change) of a running programmable controller, read the relevant manuals carefully and ensure that the operation is safe before proceeding.
  • Page 11 [Operating Precautions] CAUTION ● When changing data and operating status, and modifying program of the running programmable controller from an external device such as a personal computer connected to an intelligent function module, read relevant manuals carefully and ensure the safety before operation. Incorrect change or modification may cause system malfunction, damage to the machines, or accidents.

    Scaling Function A temperature input module performs scale conversion from a measured temperature value to a value calculated using the ratio (%) of the set scaling width to the set scaling range. The converted value is stored in the buffer memory area. The calculation of a value is performed using a scaling range upper limit value, scaling range lower limit value, scaling width upper limit value, and scaling width lower limit value, all of which are set arbitrarily.
  • Page 26 Calculating the scaling value The scale conversion is based on the following formulae. (In scale conversion, values are rounded off to the nearest whole number.) The calculation formula for a scaling value varies depending on the relationship of a scaling range upper limit value and scaling range lower limit value.

  • Page 32 Operation ■Operation performed when an alert is output Measured temperature values are monitored on the rate alarm alert detection cycle. When a change rate of a measured temperature value (from a previous value) is equal to or more than the rate alarm upper limit value, or the rate is equal to or less than the rate alarm lower limit value, an alert is output as follows.

To monitor that an increase rate of a measured temperature value is within the specified range Change of the measured Rate alarm upper limit value temperature value (­)
  • Page 35 Operation performed when disconnection is detected • At disconnection detection, a rate alarm may occurs as well because 'CH1 Measured temperature value' (Un\G400) changes according to 'CH1 Conversion setting at disconnection detection' (Un\G531). • At recovery time from disconnection, previous information (value) of rate alarm is cleared. Therefore, at the restart of temperature conversion, even if the change rate of the measured temperature value (from before restart to after restart) is out of the limit range, an alert is not output.

  • Page 37 ■Measured temperature value after the recovery A correct measured temperature value is stored in the buffer memory area at the next temperature conversion after Normal (0) is stored in 'Disconnection detection flag' (Un\G41). For averaging processing, a correct measured temperature value is stored in the buffer memory area after Normal (0) is stored in 'Disconnection detection flag' (Un\G41) and the averaging process cycle has elapsed.
  • Page 38 ■Any value At the time of the disconnection detection, a value set in 'CH1 Conversion setting value at disconnection detection' (Un\G532) is stored in 'CH1 Measured temperature value' (Un\G400). The default value of 'CH1 Conversion setting value at disconnection detection' (Un\G532) is 0. The value can be changed to any value although using 0 is no problem. When the scaling function is used, a value according to the setting of 'CH1 Conversion setting at disconnection detection' (Un\G531) is scale converted and then stored as a scaling value.
