  • Page 9 [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 10 [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.

Set a judgment value to detect heater disconnections and output OFF-time current errors as a rate (%) of the reference heater current value in "Heater disconnection alert setting"...
  • Page 90 Heater disconnection correction function When a heater voltage drops, a heater current is reduced. The R60TCTRT2TT2BW and R60TCRT4BW detect heater disconnections by measuring a heater current. Thus, an accidental alert may be issued due to the voltage fluctuation caused when a heater voltage drops. The heater disconnection correction function corrects the amount of the heater current reduced (heater disconnection correction), preventing the disconnections from being detected.
  • Page 91 ■Restrictions • When only one channel has been used, the heater disconnection correction function does not work. To use this function, two or more channels have to be used. • When multiple channels have been used with a heater that is ON in one channel and heaters that are OFF in the other channels, the heater disconnection correction function does not work.
  • Page 92: Output Off-Time Current Error Detection Function

    1.28 Output Off-time Current Error Detection Function Transistor output errors can be detected using this function. A current sensor (CT) for heater disconnection detection is used to check for errors of when transistor outputs are OFF. A heater current process value and the heater disconnection alert current value are compared. If the heater current process value is larger than the heater disconnection alert current value, an output off-time current error occurs.
  • Page 93: Loop Disconnection Detection Function

    1.29 Loop Disconnection Detection Function This function detects errors that occurs in a control system (control loop) such as a load (heater) disconnection, an externallyoperable device (such as a magnetic relay) failure, and input disconnections. How an error is detected From the point where the control output has reached the upper limit output limiter value or the lower limit output limiter value, the variation amount in the temperature process value (PV) is monitored every unit time set and heater and input disconnections are detected.
  • Page 94 ■Setting a dead band Set the non-alert area having the set value (SV) at the center (temperature width in which no loop disconnection is detected) to prevent accidental alerts of the loop disconnection detection. When the temperature process value (PV) is within the loop disconnection detection dead band, an alert is not output even though the loop disconnection alert conditions have been satisfied.

    1.30 During AT Loop Disconnection Detection Function This function detects loop disconnections during AT (auto tuning). A channel that does not follow the control can be detected by using this function. An error channel can be detected faster than the set time in which the auto tuning ends in failure.
