The commissioning mode is activated on a device of the protective device constellation and also affects the
device at the other end of the protected object (indication no. 3193
mode has to be deactivated on the device on which it was activated.
The commissioning mode can be activated/deactivated as follows:
•
Operation panel: Menu Control/Taggings/Set: "Commissioning mode"
•
Via binary inputs (no. 3260
•
In DIGSI with Control / Taggings: "Diff: Commissioning mode"
Functional Descriptin
Below, the logic is shown in a simplified way:
[logik-ibs-modus, 1, en_US]
Figure 2-21
There are two ways to set the commissioning mode. The first way is to use a command (commissioning mode
on / commissioning mode off) which is generated either when operating the integrated keypad or when oper-
ating with DIGSI. The second way is to use the binary inputs (no. 3260
OFF ).
Depending on the way used for controlling the commissioning mode, either the indication
(no. 3262) or
Comm 87 ONoffBI (no. 3263) is generated. The way used for deactivating the commissioning
mode always has to be identical to the way used for activating. The indication
generated independently of the chosen way.
The following figures show possible variants for controlling the binary inputs. If a switch is used for control
(Figure
