    The next section explains how to use the Input menus to configure your Scanner. Input Type This is the first menu of the Setup Channel Inputs menu, it lets you configure the input sensor for each channel as one of these input types. •...

  • Page 36: Channel Name

    Channel Name This menu lets you enter a channel name (up to seven characters) from this menu. If no name is entered, the Channel name will default to the current channel number. Input Units The Input Units menu lets you choose a three-character description of the channel’s engineering units.
  • Page 37 The example below shows a high PV of 10 PPM, and a low PV of 0 PPM. The high reading is the high end of the input signal (where 20 mA = 100%). Before you enter the values that determine the two points for the conversion line, you must choose an appropriate display format.

  • Page 38: Display Format

    Display Format This menu lets you select a display format for a linear input. Choose a format appropriate for your input range and accuracy. (You will only see the Display Format menu if you are editing a linear input.) The Scanner has several available display formats; the display format you choose determines the default values for the rest of the Linear Scaling Menus.
  • Page 39 Input Scaling High Reading CHANNEL PROCESS UNITS ÿþ þÿÿ CHANNEL NAME ALARM STATUS Use this menu to enter the input level that corresponds to the high process value you entered in the previous menu. For Linear Inputs, the high reading is a percentage of the full scale input range.

  • Page 40: Input Filter

    Input Filter The Scanner has two different types of input filters: • A noise rejection filter that rejects high frequency input signal noise. This filter keeps a “Trend Log” of input readings. If a reading is outside the filter’s “acceptance band”, and later readings are within the acceptance band, the Scanner ignores the anomalous reading.

  • Page 41: Process Alarms

    global alarm stays on until you use the front panel key (or ANASCAN) to acknowledge it. Process Alarms Process alarms include Alarm, Warning and Trouble alarms. You can set each of these alarms to Off, Latched or Unlatched. Function Description No Alarm Digital output activates on alarm.

  • Page 42: Alarm Delay

    Use menus to set the following process alarm parameters for each channel: • Alarm Warning and Trouble, setpoint, and digital output. • Alarm deadband • Alarm delay The setpoints, deviation alarm values, and deadband all use the same decimal format as the channel’s process variable. Alarm Delay You can set the Scanner to delay normal alarm detection and alarm reporting.

  • Page 43: Alarm Setpoint

    Alarm Setpoint This menu lets you select the setpoint (value within the scaled sensor range) at which the Alarm activates. The Alarm activates when the process variable (PV) goes above the Alarm setpoint. It deactivates when the PV goes below the Alarm setpoint minus the deadband value, if you have set a deadband value.
  • Page 44 Warning Value This menu lets you set the Warning band width, a positive and negative warning point relative to the setpoint. If the setpoint changes, the warning points also change. You can assign separate digital outputs to Hi and Lo Warnings. Selectable Values: 0 to 255, 35.5, 2.55, .255 or .0255, depending on the way you set up the Input menus.
  • Page 45 Warning Low This menu turns off Warning Low or sets it to the alarm function. Selectable Values: Off, Latched, Unlatched Warning Low Output Number This menu is used to assign a digital output that activates when the channel is in Warning Low Selectable Values: 1 to 34, None NOTE...

    Trouble Type This menu lets you turn off the Trouble Alarm, or set it to the Alarm Function. Selectable Values: Off, Latched, Unlatched Trouble Output Number This menu lets you assign the digital output that activates when the channel is in Trouble.
  • Page 47 Alarm Delay This menu sets a Channel Alarm Delay. There are two types of Alarm Delay: the Startup Alarm Delay, and Channel Alarm Delay. Startup Alarm Delay (which you can set in the Setup Global Parameters main menu), delays process alarms for all channels for a specified time after the Scanner powers up.

  • Page 48: Digital Output Selection

    Digital Output Selection This menu lets you select one of the Digital Alarm Outputs, to test in the next menu. Digital Output Test This menu lets you manually toggle a digital output On or Off to test it. (Select the output to test in the previous menu.) On may be Low or High depending on the digital output polarity you set.
