    Outputs Four outputs are available on the motherboard. Output programming information can be found in Chapters 4, 6 and 7. Each output circuit is capable of sinking 100mA current when using the internal +Vdc (5-6 volt) as a voltage source. Output sink current can be increased to 200mA when using an external voltage source.

  • Page 23: Chapter 4 Setup Mode

    Front Panel Setup Mode The GuardianXL is configured using a menu of parameters in the setup mode. Four navigation pushbuttons are used to move through the menus and change parameter settings see Figure 2.1 in Chapter 2 for location of these pushbuttons.
  • Page 24 The secondary display will then read ACCESS SETUP MD ENTER PASS CODE. Enter 2580 and the GuardianXL will enter the setup mode. The pass code will be echoed to the primary display to provide confirmation of pushbutton presses. If any error occurs while entering the pass code, simply re-enter the pass code.

  • Page 30 Output / Function This parameter selects the function or output to be configured with the triggers in this section. By selecting an output or function, allows trigger configuration that defines the active and inactive states for that particular output or function. If left in the Off selection, the trigger section will be bypassed and the menu will advance to Remote Input below.
  • Page 31 Batch Step A batch mode control parameter. This parameter allows a sequence number to be assigned to a given setpoint or function. Once an output or function has been assigned a step number, it will be active only when the scale is executing that particular step in the batch sequence.

These parameters incorporate any input or combination of inputs to activate or inactivate the setpoint. Inputs are available in the Digital I/O Option through a dry contact. Also note that it is possible to tie outputs to inputs in the Digital I/O Option.
  • Page 33 Latch Status This allows a latching flag to be used as a trigger. The flag can be set or cleared by any combination of the four outputs. See Config Set Latch on how to set and clear this flag. The output or function ignores this trigger. This trigger is true when the flag has been set.

  • Page 42: Calibration Mode Configuration

    Calibration Mode Configuration Count By and Capacity Configuration Procedure The GuardianXL allows the user to calibrate to any capacity and resolution, only limited by the number of displayable digits and maximum displayed resolution of 50,000 divisions. Calibrating the GuardianXL consists of three steps: setting the resolution and capacity, calibrating zero, and calibrating the span.
  • Page 43 CAL: Units This parameter displays the calibration units. The first line of secondary display shows the current units in the right most two characters of the first line. It is possible to calibrate in any of the units below. user Allows a user defined non-metrological unit to be defined.
  • Page 44 CAL: Count By Displays the current scale resolution in the display. The resolution is displayed in the units selected in CAL: Units. The resolution is what the scale counts by in the weigh mode. For instance with a 500 x 0.1 lb capacity and resolution the count by value would be 0.1 lb.
  • Page 45 The GuardianXL allows span weight calibration to be performed prior to the zero weight calibration. The GuardianXL will also allow span calibration to occur by removing a known weight rather than adding weight.
  • Page 46 100.00. Press menu. You can now switch between any active unit and user units. Example 3 Units Count By Check: An important feature of the GuardianXL is the ability to change units once configuration has started. Let’s take our previous example, of the 20lb scale.

  • Page 47: Figure 5.3 Meteorological Parameters Map

    Under a legal for trade application, these parameters must be properly configured to conform to the certificate of conformance issued by NCWM for the GuardianXL. These parameters are tracked by the parameter audit trail and hence protected with a pass code in the calibration mode.
  • Page 48 The unit of this setting is divisions. Therefore a scale calibrated to 500 x 0.1 lb capacity and resolution would have 0.1 lb as one division. The motion indicator is activated when the GuardianXL detects scale platform motion over the threshold setting. This setting must be configured properly when in a Legal for Trade application.
  • Page 49 When activated, start up zero automatically zeros the scale as a part of the start up routine when the GuardianXL is turned on. It is recommended to leave this parameter off with battery powered systems as it will preserve any weight left on the scale if the GuardianXL goes into sleep mode.
