    C2-4 C2.1 Input Type Selection Input types may be selected either using hardware switches (for all channels collectively) or using parameters (for individual channels). Input type selection using parameters is available only when switches SW1-4 = OFF and SW5 = 0. Input type selection by parameters uses the Input Type Selection (IN) parameter.

  • Page 97: Power Supply Frequency Selection

    C2-7 C2.2 Power Supply Frequency Selection Power supply frequency may be set either by switches or parameters. Power supply frequency selection by parameters is available only when switches SW1-4 = OFF and SW5=0. The default value is then determined by SW1-2. An appropriate power supply frequency setting reduces the interference of common-mode noise from the power supply on input signals.

  • Page 98: C2.3 Input Range Setting

    C2-8 C2.3 Input Range Setting For each instrument range selected, you may define an input range, which is the actual temperature range to be monitored, by specifying upper (RH) and lower (RL) limits within the instrument range. Some input types such as thermocouple W, however, allow an input range that is wider than the instrument range.

  • Page 99: C2.4 Pv Range Setting (For Two-Input Changeover Mode)

    C2-9 C2.4 PV Range Setting (for two-input changeover mode) The PV range setting defines the range of the output process value in Two-input Changeover mode, in cases where the two input signals have different input ranges. The PV range setting cannot be changed in Single-input mode. For example, if input 1 (channel 1) has input range of 0-500C (RL=0C;...

  • Page 100: C2.5 Burnout Detection

    C2-10 C2.5 Burnout Detection Burnout detection checks for an open circuit on an input. For thermocouple or RTD input, you may define a burnout condition by specifying a threshold value and the direction of change in the input value. For DC voltage input, burnout detection is not available.
  • Page 101 C2-11 CAUTION Burnout detection is not performed when external input (EXPV) is selected. CAUTION If the Burnout Selection parameter is set to ‘Down Scale’ for a thermocouple range, a burnout may not be detected in high temperature environments exceeding 40C. In this situation, set the alarm type to ‘Lower Limit’, set the alarm setting to an appropriate value, and use the alarm for burnout detection instead.

  • Page 103: Broken-Line Biasing

    C2-13 C2.7 Broken-line Biasing The broken-line biasing function biases an input value according to its magnitude. This function is especially useful for correcting input values from a degraded sensor. As shown in the figure below, you will define three input values (X) and specify a bias value (Y) for each input value.

  • Page 104: C2.8 Fixed Biasing

    C2-14 C2.8 Fixed Biasing The fixed biasing function adds a constant bias to input values. The resultant values are used for monitoring. This function is especially useful when a sensor output is always lower than true values by a fixed amount due to the physical condition of the sensor. For example, it may be used when the temperature of a material in a furnace is indirectly determined by measuring the ambient temperature in the furnace, where a fixed bias is added to the ambient temperature to represent the temperature of the material.

    C2-15 C2.9 Square Root Extraction The square root extraction function is especially useful for converting differential pressures measured with a restriction flowmeter using an orifice or nozzle into flow rates. You can also specify a low-cut point below which no square root extraction is done. 100.0% Slope 1 Input...

  • Page 106: C2.10 Input Filtering

    C2-16 C2.10 Input Filtering The input filtering function removes noise from input signals. It is especially useful to remove high frequency noise from flow rate or pressure signals. It performs 1st order delay calculation for filtering. As shown in Figure C2.6, more noise is removed when a larger time-constant is specified. Use the input filtering function in a noisy environment when corrections must be performed constantly.

  • Page 108 C2-18 If two inputs have different values, switching between the two inputs may result in an abrupt change in the PV value or a non-continuous PV value. To prevent this, this mode uses the average of the two inputs to compute the PV value in the overlapping range, as shown in the formula above.

  • Page 109: C2.12 External Input

    C2-19 C2.12 External Input The input value used in monitoring may be switched to an external input, which may be, say, processed data from a CPU module. An external input must fall within the range of -5.0% to 105.0% of (SL to SH). Use the EXPV/PV parameter to switch between external input and normal input.

  • Page 116: C3.3 Alarm Delay Timer

    C3-6 C3.3 Alarm Delay Timer The alarm delay timer function delays the generation of an alarm. The alarm turns on only if the alarm condition persists until a delay timer has timed out. If an alarm condition disappears before a delay timer has timed out, the timer resets. Changing an alarm type or powering down also resets the delay timer.

    C4-1 Disable Backup Function The Disable Backup Function (NBKUP) parameter can be used to suspend storing of parameters to the EEPROM. The module has two types of parameters: stored and non-stored. Stored parameters preserve their data even when the module is powered down.
