Operating Installed ModulesAll 6800+ modules and some 6800/7000 modules can be operated and monitored using card-edge controls. Check the individual module manual that comes with your product to identify which frames are compatible with the module. Each module has a different set of operating parameters and controls. See the individual product manual that accompanies your module for operating details.

Using Card-Edge Controls Many modules contain controls that include two control switches and a series of LED indicators on the module’s card-edge. The two card-edge switches, the mode select rotary switch, and the navigation toggle switch work together to provide access to all of the parameter banks and control options on the module. Figure 3-2 illustrates the location of these switches.

Figure 3-2. Card-Edge Controls

NotePosition “0” permits the navigation toggle switch to select a bank.

Mode select rotary (hex) switch

Navigation toggle switch



The mode select rotary switch (hex switch) selects the parameter type. Rotate the switch until you see the number (1 to 9) or letter (A to F) that corresponds with the desired parameter. To view hex switch positions and corresponding banks and controls, see the table entitled “Card-Edge Parameter Options” in the individual product manual that accompanies your module.

NoteSome 6800+ modules can be used in both horizontal and vertical configurations. Ensure that you follow the Up and Down markings on the module to increase or decrease parameter values, respectively.

The navigation toggle switch selects a bank (when the hex switch is set to “0”) and individual parameter values. Follow the markings on the module board (Up and Down) to set a parameter value.• Toggle the switch Up through the list of banks or to increase the

parameter value. • Toggle the switch Down through the list of banks or to decrease the

parameter value.See the section titled “Changing Parameter Settings” in the individual product manual that accompanies your module for more information.

Introducing Parameter TypesMost 6800+ parameters are adjustable and can be set using either card-edge controls (see “Using Card-Edge Controls” on page 17) or a software control application. However, some parameters are considered “read-only” and cannot be changed. These parameters (indicated by the abbreviation “[RO]”) provide status and feedback information only.Parameter lists may wrap or clip. If the list is set to wrap, it returns to the beginning of its range or options after you have toggled through all of them. Clipping requires you to scroll back through the options to return to the beginning of the list.



Wrapping is only available from the card edge. Parameters that normally wrap when adjusted via the card edge will clip when adjusted using a control software application.

NoteControl software is not available with the FR6800+MB.

Adjustable ParametersTwo types of adjustable parameters can be changed using the card-edge controls:• Numerical parameters, which require you to select a value within a

numerical range (for example, between 0 and 524)• Selectable parameters, which require you to select a specific option

(for example, 525 or 625)Both numerical and selectable parameter changes are immediate.

NoteSee the table titled “Card-Edge Parameter Options” in the individual product manual that accompanies your module to view the various numerical and selectable parameters for the module.

Read-Only ParametersMany of the read-only parameters have related LEDs on the front of the module’s card edge. See the section “Monitoring LEDs” in the individual product manual that accompanies your module for information on the location of these LEDs.

Operating NotesWhen setting the control parameters, observe the following:• If you make changes to certain parameters, other related parameters

may also be affected. See the section “Cross-Functional Parameter Changes” in the individual product manual that accompanies your module for more information.

• When you change a parameter, the effect is immediate. However, the module requires up to 30 seconds to save the latest change. After 30 seconds, the new settings are saved and will be restored if the module loses power and must be restarted.

Troubleshooting

OverviewBefore contacting a Customer Service representative to resolve a technical issue, review the following topics found in this appendix:• “Using 6800 Series Modules in FR6800+MB Frames” on page 30• “Getting Help from Customer Service” on page 31


Appendix B: Troubleshooting

Using 6800 Series Modules in FR6800+MB Frames

Most 6800 series modules (non + series) housed in an FR6800+MB frame can be operated and monitored using card-edge controls. The FR6800+MB frame is designed to house and power both 6800 and 6800+ modules. Although the 6800+ modules have different features and controls, both work in harmony with each other in the FR6800+MB frame. Compare your installed 6800 series modules with the modules listed in the document Installing Compatible 6800/7000 Modules in FR6802+XF Frames, which is available for download from our Web site. Remove those installed 6800 series modules that are not compatible with the FR6800+MB frame.

CautionThe front module must match the corresponding back connector; otherwise, the modules will not operate correctly. Some module insertions may be prevented if the modules are incompatible.
