SELECT/SET button
WARNING
EXPLOSION HAZARD
Do not press the SELECT/SET button when there is an explosive atmosphere.
Function
The SELECT / SET button is used to switch over the display modes (DMode) and to make
other settings. After turning on the IE Switch X-400, it is in DMode A.
The button has the following functions:
●
Changing the display modes
By pressing the button briefly, you change from one display mode to the next. The
selected mode or current status is displayed by the LEDs (D1, D2).
●
Resetting to the factory defaults
It is possible to restore some of the factory defaults in DMode A. by pressing the button
for 12 seconds. You can cancel the reset procedure by releasing the button before the 12
seconds have elapsed. All previously made settings are overwritten by the factory
defaults.
●
Defining the fault mask and the LED displays
It is possible to set the fault mask in DMode A and DMode D. This allows you to specify
the mask for signaling faults by defining an individual "good status" for the connected
ports and the power supplies. In this case, you press the button for 5 seconds in DMode
A or DMode D. After 3 seconds, the two LEDs (D1 and D2) start to flash. You can cancel
the procedure by releasing the button before the 5 seconds have elapsed. If, however,
you press the button for a further 2 seconds, the current states of all ports and the states
of the power supplies L1 and L2 are included in the fault mask. The previous fault mask is
then overwritten.
●
Activating/deactivating the redundancy manager (only with the SCALANCE X408-2 basic
device)
It is only possible to activate/deactivate the RM in DMode B by pressing the button for 5
seconds. After 3 seconds, the two LEDs (D1 and D2) start to flash. If you release the
button before the 5 seconds have elapsed, the action is aborted. After 5 seconds the
redundancy manager is activated/deactivated. If the redundancy manager as well as ring
redundancy were deactivated, ring redundancy is also activated at the same time. If you
deactivate, only the redundancy manager is deactivated.
