7.1.2 Main Menu Mode
Both the GLCP and NLCP provide access to the main menu mode. Select
main menu mode by pressing the [Main Menu] key. Figure 6.2 shows the
resulting read-out, which appears on the display of the GLCP.
Lines 2 through 5 on the display show a list of parameter groups which
can be chosen by toggling the up and down buttons.
Each parameter has a name and number which remain the same regardless of the programming mode. In main menu mode, the parameters are divided
into groups. The first digit of the parameter number (from the left) indicates the parameter group number.
All parameters can be changed in the main menu. The configuration of the unit (par. 1-00
for programming. For example, selecting Closed-loop enables additional parameters related to closed-loop operation. Option cards added to the unit
enable additional parameters associated with the option device.
