5 Editing Parameters
5.1 Parameter Access Levels
You can edit SED2 VSD parameters via the AOP. Access levels control access to the SED2 VSD parameters.
A higher access level corresponds to a more sophisticated level of control techniques available for the SED2
VSD applications. User Access Level parameter P0003 sets the access level as follows:
• P0003=0 User Defined List
• P0003=1 Standard Parameters
• P0003=2 Extended Parameters
• P0003=3 Expert Parameters
The access level defined for a SED2 VSD (not the AOP) determines the access to the various levels of pa-
rameters. Extended level parameters permit access to all Standard level parameters as well as several others.
Expert level parameters permit access to all Extended and Standard level parameters, as well as indexed pa-
rameters. Parameter indexes provide subsets of a particular parameter function. The indexes group together
closely related parameter type information.
5.2 Editing Conventional Parameters
Note: All parameters that are changed using the following procedures are changing the physical parameters
on the SED2 connected to the AOP.
Use the following procedure to change parameters in the SED2 VSD that connects to the AOP:
1. From the main menu, use
and to scroll through the list of options and to highlight the PARAME-
TERS item.
Press
to confirm the selection.
The AOP displays a parameter screen so you can select the desired parameter group or access level.
2. Use
and to scroll through the parameter groups and to highlight the desired group. Press to
confirm the selection.
When you select a parameter group, the AOP displays the first parameter in ascending numerical order.
3. Use
and to scroll through the list of parameters and to highlight the desired parameter. Press to
confirm the parameter selection and the cursor advances to the parameter value.
4. The AOP displays the values associated with the selected parameter. Use
and to change the pa-
rameter value as desired.
Note: The AOP only accepts parameter values within a predefined range. An out-of-range value is re-
jected and the AOP prompts you to enter a correct value.
5. Press
to confirm the new parameter value.
The AOP returns to the parameter screen so you can select another parameter, if desired.
Press
to return to the r0000 display.
Press
again to return to the previous menu.
Press
for several seconds to return to the status screen (normal operating mode). The parameter value
that has been changed is retained within the AOP’s internal memory, but not sent to the SED2. Should
power to the SED2 or AOP be interrupted, all changes are lost.
