Error release with the "Service" button

An error-locked safety monitor (red LED 3 OFF/FAULT flashes) can be released by
pressing the "Service" button. The module with the error is reset when the button is
pressed. A start test must be performed on this module after the reset.

Replacing defective safe AS-i slaves

10.4.1 Replacing a defective safe AS-i slave
If a safe AS-i slave is defective, it is possible to replace it without a PC and without
reconfiguring the AS-i safety monitor by using the Service button on the AS-i safety
monitor.
Notice!
When the Service button is pressed, the safety monitor switches from protective
operation to configuration operation. The output circuits are therefore deactivated in all
cases.
Proceed as follows:
1. Disconnect the defective AS-i slave from the AS-i line.
2. Press the Service button for approx. 1 second on all AS-interface safety monitors
which use the defective safe AS-interface slave.
3. Connect the new safe AS-i slave to the AS-i line.
4. Press the Service button again for approx. 1 second on all AS-interface safety
monitors which use the replaced safe AS-interface slave.
5. The first time the Service button is pressed, the monitor determines whether
exactly one slave is missing. This is noted in the error memory of the AS-i safety
monitor. The AS-i safety monitor switches to configuration operation. The second
time the Service button is pressed, the code sequence of the new slave is read in
and checked for correctness. If the code sequence is OK, the AS-i safety monitor
returns to protective operation.
Attention!
After replacing a defective safe slave, make certain to check the new slave for correct
function.
10.4.2 Replacing several defective safe AS-i slaves
If more than one safe AS-i slave on an AS-i network is defective, the devices must be
replaced in the following way:
Notice!
When the Service button is pressed, the safety monitor switches from protective
operation to configuration operation. The output circuits are therefore deactivated in all
cases.
1. Disconnect all defective AS-i slaves from the AS-i line. Connect all new, already
addressed safe AS-interface slaves except one to the AS-interface line
(Auto_Address does not function in this case).
2. Activate all newly connected slaves so that no code sequences are sent by the
slave (actuate emergent stop, open door, break light barrier, etc.).
