Procedures for setup

INFO

The complete parameter list is presented in the separate Parameter List document of the Multi-line unit in question:

GPC/GPC Gas/GPC Hydro/GPU Hydro document number 4189340580, GPU/GPU Gas/PPU document number

4189340581.

This chapter deals with the procedure to be followed when the parameters of the unit are set up from the initial point of finding the

individual parameter description to the actual setup. By use of various illustrations, the following will guide the user through the

whole procedure of parameter setup step by step.

6.2 Finding the selected parameter

The first step in the parameter setup is to find the correct parameter descriptions. All parameter descriptions in the Parameter List

document are intended for reference purposes. The descriptions are structured according to their parameter titles and the main

parameter group to which they belong.

6.3 Parameter descriptions

In the parameter list, each parameter description is structured according to the same principles. Under the parameter title heading,

the detailed parameter descriptions are illustrated and presented. First, a table indicating the parameter facts related to the

individual parameter title is presented:

INFO

Due to the character of the parameters there may be small differences between the individual tables.

The first column indicates the menu number in the display.

The second column indicates the name of the setting.

The third column describes the function of the parameter.

The fourth column indicates the minimum/maximum set point available for this setting

The fifth column indicates the default set point of the unit from the factory. When it is necessary, additional information will be

supplied below the table in order to make the individual parameter descriptions as informative as possible.

6.4 Setup

At this point of the process, the specific parameter description will have been located. Now, follow the menu structure presented

earlier in this manual to set up the individual parameters. (In this overall example, we have chosen to change the set point of the

parameter 1000 G -P>).

Step 1: Enter the setup menu via SETUP in the fourth display line in the entry window. 

Step 2: Enter the protection menu via PROT in the fourth display line in the setup menu. 

Step 3: Use the and push-buttons to locate the selected parameter.

Step 4: Enter the set point menu via SP in the fourth display line. 

Step 5: Enter password to change the set point. 

Step 6: Use the and push-buttons to increase/decrease the set point setting.

Step 7: Move the “underscore” to save and press SEL; the new set point setting has now been saved.
