Navigation in the menu
There are basically two ways of navigating in both menus:
●
Press and release the shift key (≤ 500 ms)
Within a menu, you can jump from one parameter to the next by pressing and releasing
the shift key. The sequence - which is fixed - is shown in the table below.
Entry Display in the RUN menu Display in the SET menu
1. Current measured value or error symbol,
switching contact symbol, and monitoring
method for diagnostics
Hysteresis
2. Threshold value for current undershoot for
the CO contact 31-32-34
ON-delay time
3. Threshold value for current overshoot for
the CO contact 31-32-34
Tripping delay time
4. Threshold value for current undershoot for
the semiconductor output Q
Reclosing delay time
5. Threshold value for current overshoot for
the semiconductor output Q
Blocking current monitoring
6. Fault current monitoring
7. Memory (automatic/manual RESET)
8. Incorrect phase sequence monitoring
9. Load current monitoring (apparent
current/active current)
10. Functional principle (closed-circuit
principle/open-circuit principle)
● Press and hold down the shift key (> 2.5 s)
Press and hold down the shift key to switch from the RUN menu to the SET menu and
vice versa.
–
RUN → SET
You can switch menus from any of the parameters. While the shift key is pressed
down, "SET?" is displayed.
When you switch menus, you are always taken to the "Hysteresis" menu command in
the "SET" menu.
In the event of an error you will only be able to switch to the "SET" menu from the
"RUN-Settings"
②
.
– SET → RUN
You can switch menus from any of the menu commands. While the shift key is
pressed down, "RUN?" is displayed and the changes to the settings are applied.
When you switch menus, you are always taken to the "Current measured value"
parameter in the RUN menu.
Note
Aborting the menu switchover
The switchover process will be interrupted if the shift key is released while "SET?" or
"RUN?" is displayed. The menu will revert to the menu command you were working
with when the switch was initiated.
