13.12.1 Use of pushbuttons
The variables described by the letters xxx, can be compiled using the
↑
or
↓
keys and confirming them with the
↵
key.
Basically, once you have entered the page you are interested in, moving from one size to the other can be done by using the
↑
or
↓
keys. On the
other hand, to change a size, once the cursor is placed over the size itself, the
↵
key must be pressed and then it becomes possible to modify
the parameters (the ‘
→
’ symbol appears on the left of the parameter) by means of the
↑
or
↓
keys. Confirmation of the parameter is carried out
by means of the
↵
key.
In the case where repeating programming of a parameter which has just been configured is necessary, it is sufficient to press the ESC key just
once and the display cursor will go back to the same line of the page selected, otherwise to return to the main menu it is necessary to press the
ESC key twice.
The RESET pushbutton must be used to reset the yellow magnetic flags and the contacts of the signaling trip unit.
The TEST pushbutton must be used to carry out the Trip test (see par. 13.11.3)
13.12.2 Read and Edit modes
The map relative to the menus displays all the pages obtainable and the movements to be carried out with the keyboard, in the “READ” mode (just
for data readout) or in the “EDIT” mode (for setting the protection parameters).
In the case when the page displayed is the one of the main menu or of other sub-menus, two different operating ways can be obtained, depending
on the state of the unit:
1. “READ”:
the page relative to the currents will be displayed automatically after about 120 seconds
2. “EDIT”:
the page relative to the currents will be displayed automatically after about 240 seconds
The functions allowed according to the state are :
