Convert
Use the Convert menu item to convert from one settings version to another.
Typically, this utility is used to upgrade an existing settings file to a newer
version because devices are using a newer version number.
ACSELERATOR
QuickSet provides a Convert Settings report that shows missed, changed, and
invalid settings created as a result of the conversion. Review this report to
determine whether changes are required.
Settings Editor
(Editor Mode)
Use the Settings Editor (Editor Mode) to enter settings. These features
include the
ACSELERATOR QuickSet settings driver version number (the first
three digits of the Z number) in the lower left corner of the Settings Editor.
Entering Settings
NOTE: Setting changes made during
the edit session are not read by the
relay unless they are transferred to
the relay with a Send menu item.
Step 1. Click the + marks and the buttons in the Settings Tree View to
expand and select the settings you want to change.
Step 2. Use Tab to navigate through the settings, or click on a setting.
Step 3. To restore the previous value for a setting, right-click the mouse
over the setting and select Previous Value.
Step 4. To restore the factory default setting value, right-click in the
setting dialog box and select Default Value.
Step 5. If you enter a setting that is out of range or has an error,
ACSELERATOR QuickSet shows the error at the bottom of the
Settings Editor. Double-click the error listing to go to the
setting and enter a valid input.
Expression Builder
NOTE: Be sure to enable the
functions you need (Logic Settings >
SEL
OGIC Enable) before using
Expression Builder.
SELOGIC control equations are a powerful means for customizing device
performance.
ACSELERATOR QuickSet simplifies this process with the
Expression Builder, a rules-based editor for programming SEL
OGIC control
equations. The Expression Builder organizes device elements, analog
quantities, and SEL
OGIC control equation variables.
Access the Expression Builder
Use the Ellipsis buttons in the Settings dialog boxes of Settings Editor
windows to create expressions, as shown in Figure 3.9.
