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.
Page 32
Input 1, Input 2, Input 3, Input 4 These four menus share the same parameter values. 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 34
Accum Clear This parameter enables or disables the Accum Clear Function used in the Accumulator / Counter recall mode. Enables use of the Accum Clear function on Accumulator/Counter. Disables use of the Accum Clear function on Accumulator/Counter. UNITS This parameter enables or disables the front panel UNITS push button function. Enables use of the UNITS push button.

Batch Cfg F1/F2 A batch mode control parameter. This parameter enables or disables the F1/F2 Pushbuttons while in batch mode. Enables use of F1/F2 batch control pushbuttons. Disables use of F1/F2 batch control pushbuttons. Batch Program A batch mode control parameter. This parameter selects the pre-programmed batch program to load into memory.
This parameter activates each output, one at a time as you scroll through the parameter values. Use this parameter to troubleshoot relays that are not activating and communications between the GuardianXL and the Digital I/O option. Once this menu is exited all outputs are inactive. No outputs are activated.
If enabled, the pass code must be entered after pressing MENU and a shortcut pushbutton. The secondary display will read ACCESS SETUP MD ENTER PASS CODE. Enter 2580 and the GuardianXL will enter the setup mode. Use pass code 60510 to enter the test mode.
The setup pushbutton is accessed by removing the two-screw access panel on the bottom of the indicator. The GuardianXL is placed into calibration mode when the pass code is entered and the pushbutton is pressed.
CALIBRATE AUDIT. The calibration audit trail tracks changes in calibration by incrementing every time the GuardianXL is calibrated. Press TARE ( ) to advance to the calibration mode entry point. The secondary display will read ACCESS CAL MODE ENTER PASS CODE.
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.
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.

4-20mA Installation If the indicator was shipped from DORAN with this option installed skip ahead to the 4- 20mA Setup section below. If you have an existing GuardianXL indicator and now require the 4-20mA option, this section will describe the installation of the 4-20mA option.
4-20mA Setup To setup the Digital I/O 4-20mA option set the Print Mode parameter to “F3” see Chapter 4 for details. The 4-20mA option is automatically calibrated for an output range of 4mA to 20mA, (i.e. 4mA equals zero gross weight and 20mA equals the scale’s capacity). If the scale is in a fault condition, the 4-20mA output levels are 3.5mA for gross underload or underload, and 24mA for gross overload or overload.
Chapter 11 Internal Fiber Optic Option Doran’s GuardianXL can be supplied with a Fiber Optic Output Option. It can be offered as part of the Digital I/O Box Option as described in Chapter 8 or it can be installed inside the GuardianXL enclosure. This chapter describes the latter.
Remove the outer nut and split bushing from the PG16 water tight. Insert each of the fiber optic ST connector ends one at a time through the PG16 outer nut. Then install the two single fiber optic cables through a split bushing using the slits on the sides (see Figure 11.2).
Appendix A Print String Formatting The GuardianXL provides six predefined print strings that are outputted when a manual print, auto print or print function is executed.
