6.1.1 Three Ways of Operating
The frequency converter can be operated in three ways:
1.
Graphical Local Control Panel (GLCP), see 5.1.2
2.
Numeric Local Control Panel (NLCP), see 5.1.3

6.1.2 How to Operate Graphical LCP (GLCP)
The following instructions are valid for the GLCP (LCP 102).
The GLCP is divided into four functional groups:
1.
Graphical display with Status lines.
2.
Menu keys and indicator lights (LED's) - selecting
mode, changing parameters and switching between
display functions.
3.
Navigation keys and indicator lights (LEDs).
4.
Operation keys and indicator lights (LEDs).
Graphical display:
The LCD-display is back-lit with a total of 6 alpha-numeric
lines. All data is displayed on the LCP which can show up to
five operating variables while in [Status] mode.
Display lines:
a.
Status line: Status messages displaying icons and
graphics.
b.
Line 1-2: Operator data lines displaying data and
variables defined or chosen by the user. By pressing
the [Status] key, up to one extra line can be added.
c.
Status line: Status messages displaying text.
The display is divided into 3 sections:
Top section (a) shows the status when in status mode or up to
2 variables when not in status mode and in the case of Alarm/
Warning.
The number of the Active Set-up (selected as the Active Set-up
in par. 0-10
Active Set-up
) is shown. When programming in
another Set-up than the Active Set-up, the number of the Set-
up being programmed appears to the right in brackets.
The Middle section (b) shows up to 5 variables with related
unit, regardless of status. In case of alarm/warning, the
warning is shown instead of the variables.
The Bottom section (c) always shows the state of the frequen-
cy converter in Status mode.
It is possible to toggle between three status read-out displays
by pressing the [Status] key.
Operating variables with different formatting are shown in
each status screen - see below.
