ABB HIEE205011R0002 inverter control cabinet logic board
Any data required during normal operation are
accessible in the main menu i.e. present measured values, present setting values and recorded
parameter values.
The data to be shown in the main menu are
sequentially called up for display by means of
the STEP push button. When the STEP push
button is pressed for about one second, the
display moves forward in the display sequence.
When the push button is pressed for about 0.5
seconds, the display moves backward in the
display sequence.
From a dark display only forward movement is
possible. When the STEP push button is pushed
constantly, the display continuously moves forward stopping for a while in the dark position.
Unless the display is switched off by stepping to
the dark point, it remains lit for about 5 minutes
from the moment the STEP push button was
last pushed. After the 5 minutes' time-out the
dispaly is switched off.
Display submenus Less important values and values not very often
set are displayed in the submenus. The number
of submenus varies with different relay module
types. The submenus are presented in the description of the concerned protection relay
module.
A submenu is entered from the main menu by
pressing the PROGRAM push button for about
one second. When the push button is released,
the red digit of the display starts flashing, indicating that a submenu has been entered. Going
from one submenu to another or back to the
main menu follows the same principle as when
moving from the main menu display to another;
the display moves forward when the STEP push
button is pushed for one second and backward
when it is pushed for 0.5 seconds. The main
menu has been re-entered when the red display
turns dark.
When a submenu is entered from a main menu
of a measured or set value indicated by a LED
indicator, the indicator remains lit and the address window of the display starts flashing. A
submenu position is indicated by a flashing red
address number alone on the dispaly without
any lit set value LED indicator on the front
panel.

Part of the settings and the selections of the
operation characteristic of the relay modules in
various applications are made with the selector
switchgroups SG_ . The switchgroups are soft ware based and thus not physically to be found
in the hardware of the relay module. The indi cator of the switchgroup is lit when the checksum
of the switchgroup is shown on the display.
Starting from the displayed checksum and by
entering the setting mode, the switches can be
set one by one as if they were real physical
switches. At the end of the setting procedure, a
checksum for the whole switchgroup is shown.
The checksum can be used for verifying that the
switches have been properly set. Fig. 2 shows an
example of a manual checksum calculation.
When the checksum calculated according to the
example equals the checksum indicated on the
display of the relay module, the switches in the
concerned switchgroup are properly set.
Switch No Pos. Weigth Value
1 1 x 1= 1
2 0 x 2= 0
3 1 x 4= 4
4 1 x 8= 8
5 1 x 16 = 16
6 0 x 32 = 0
7 1 x 64 = 64
8 0 x 128 = 0
Checksum ∑ = 93

a selector switchgroup SG_.
The functions of the selector switches of the
different protection relay modules are described
in detail in the manuals of the different relay
modules.
