Replacing A Defective As-I Safety Monitor - Leuze lumiflex ASM1E Connecting And Operating Instructions

Notice!
The error detection function integrated in the monitor only accepts a new slave if point
2 is fully observed.
3. Press the Service button for approx. one second on all AS-interface safety
monitors which used the defective safe AS-interface slaves.
4. Connect the last missing and already addressed slave to the AS-interface line.
5. Press the Service button for approx. one second on all AS-interface safety
monitors which used the defective safe AS-interface slaves.
6. Disconnect one of the replaced and not yet taught AS-interface slaves from the
AS-interface line.
7. Press the Service button for approx. one second on all AS-interface safety
monitors which used the defective safe AS-interface slaves.
8. Reconnect the previously disconnected AS-i slave to the AS-i line.
9. Activate the newly connected slave. The code sequence is now transmitted to the
AS-interface safety monitor and stored there.
10. Press the Service button for approx. one second on all AS-interface safety
monitors which used the defective safe AS-interface slaves.
11. Repeat the procedure from step 6 onwards until all replaced AS-interface slaves
have been taught.
12. 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 the defective safe slaves, make certain to check the new slaves for
correct function.

Replacing a defective AS-i safety monitor

If an AS-i safety monitor is defective and must be replaced, the replacement device
does not necessarily need to be reconfigured using the asimon software. It is possible
instead to transfer the configuration from the defective device to the replacement
device using the download cable (Chap. 13: Scope of delivery).
Requirements:
• A download cable must be available (see accessories in Chapter 13).
• The replacement device must not have a valid configuration stored in its configura-
tion memory.
Notice!
If an AS-interface safety monitor which was previously used somewhere else is now to
be used as a replacement device, you must replace the existing old configuration with
a new configuration which, however, you should not validate.
