AS-Interface
Status indication, faults and fault elimination
If the safety unit is in the
red flashing
state and no menu is open, the safety unit
can be unlocked by pressing the ESC/Service key (Section <Function of the
ESC/Service key>).
•
If the message “Fatal Error” is reported from the safety unit, only this error
message will be displayed in normal mode (not the menu). The non-safe unit
continues to operate normally in this case and the menus can also be
opened.
•
All other messages are not shown spontaneously.
If the safety unit is in the
yellow flashing
state, depending on the status of the con-
figuration an external test may be required, an acknowledgement of the status
may need to be made, or the turn-on delay active.

Replacing a defective safety-configured AS-i slave
If a safety-configured AS-i slave is defective, it can be replaced even without a
PC or reconfiguration of the AS-i Safety Monitor by pressing the ESC/Service key
on the AS-i Safety Monitor.
Proceed as follows:
1.
Disconnect the AS-i slave from the AS-i cable.
2.
Press the ESC/Service key on the AS-i Safety Monitor and on all other
safety monitors for approx. 3 seconds.
3.
Connect the new safety-configured AS-i slave, which has already been pro-
grammed to the corresponding address, to the AS-i cable.
4.
Press the ESC/Service key again on the AS-i Safety Monitor and on all
other Safety Monitors which use the replacement safe AS-i slave for
approx. 3 seconds. The code table for the new slave is taught and checked
for correctness.
If this is OK, the AS-i Safety Monitor changes to protecting mode. Otherwise
you are prompted again to teach.
