1.1.1 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 tota l of 6 a lpha -n umer ic l ines. All data is displa yed o n the L CP wh ich c an show up to five operatin g variables wh ile 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 de-

fined 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) 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.

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. 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.

Several values or measurements can be linked to each of the displayed o pera ting variables. The values / measurements to be displayed can be defined via par. 0-20, 0-21, 0-22, 0-23, and 0-24, which can be accessed via [QUICK MENU], "Q3 Function Setups", "Q3-1 General Settings", "Q3-11 Display Settings".

Each value / measurement readout parameter selected in par. 0-20 to par. 0 -24 has its o wn scale and n umber of digits aft er a possible deci mal point. Larger numeric values are displayed with few digits after the decimal point. Ex.: Current readout

2.2.3 0-1* Set-up Operations

Define and control the individual parameter set-ups. The frequency converter has four parameter setups that can be programmed independently of each other. This makes the frequency converter very flexible and able to meet the requirements of many different AQUA system control schemes often saving the cost of external control equipment. For example these can be used to program the frequency converter to operate acco rding to one contro l sche me in o ne setup (e. g. dayt ime o perati on) a nd another control scheme in another setup (e.g. night set back). Alternatively they can be used by an AHU or packaged unit OEM to identically program all their factory fitted frequency converters for different equipment models within a range to have the same parameters and th en during production/commissioning simply select a specific setup depending on which model within that range the frequency converter is installed on.

2 Parameter Description VLT® AQUA Drive Programming Guide

The active setup (i.e. the setup in which the frequency converter is currently operat i n g) can be selected in parameter 0-10 and is displayed in the LCP. Using Multi set-up it is possible to switch between set-ups with t he frequency con verter running or stopped, via digital input or serial communication commands (e.g. for night set back). If it is necessary to change setups whilst running, ensure parameter 0-12 is programmed as required. For the majority of AQUA applications it will not be necessary to program parameter 0-12 even if change of set up whilst running is required, but for very complex applications, using the f ull fl exib il ity of th e mu lt iple set ups, it may b e re qui red.

To enable conflict-free changes from one set-up to another whilst the frequency converter is running, link set-ups containing parameters which are not changeable during operation. The link will ensure synchronisi ng of the ‘not changeabl e during o peratio n’ paramet er value s when movi ng from one set-up to another during operation. ‘Not changeable during operation’ parameters can be identified by the label FALSE in the parameter lists in the section

It is possible to program the clock for Daylight Saving Time / summertime, weekly working days/non- working days including 20 exceptions (holidays etc.). Although the clock settings can be set via the LCP, they can also be set along with timed actions and preventative maintenance functions using the MCT10 software tool.

NB!

The frequency converter has no back up of the clock function and the set date/time will reset to default (2000-01-01 00:00) after a power down unless a Real Time Clock module with back up is installed. If no module with back up is installed, it is recommended the clock function is only used if the frequency converter is integrated into an external system using serial communications, with the system maintaining synchronization of control equipment clock times. In par. 0-79, clock has not been set properly, e.g. after a power down.
