8.1.3 Protective Operation - Leuze lumiflex ASM1E Connecting And Operating Instructions

• sending the command stop while in protective operation from the asimon software
without entering a password. This is only possible if there is no communication on
the AS-i line. You can ensure that this is the case by, for example, directly
disconnecting the AS-i line from the monitor.
• detecting a missing or faulty configuration in start-up operation.
• pressing the Service button for the first time when replacing a defective safe AS-i
slave (see chapter 10.4 "Replacing defective safe AS-i slaves").

8.1.3 Protective operation

Protective operation is the normal operating mode of the AS-i safety monitor. In this
mode the output switching elements are activated and deactivated depending on the
operating state of the monitored safe AS-i slaves and configured functional compon-
ents.
In protective operation, the AS-i safety monitor continuously transmits diagnostic data
via the serial configuration interface. This data is processed by the asimon software.
If an internal error function is detected during protective operation of the AS-i safety
monitor, the output switching elements are switched off immediately and without regard
to any set delay times. The AS-i safety monitor then performs a self test again. If the
error no longer exists, the AS-i safety monitor returns to protective operation. If the
error still exists, this state is error-locked and can be exited only by switching the AS-i
safety monitor back on.
It is possible to switch to protective operation by
• sending the command start while in configuration operation from the asimon
software.
• detecting a valid, validated configuration in start-up operation.
• pressing the Service button for the second time when replacing a defective safe
AS-i slave (see chapter 10.4 "Replacing defective safe AS-i slaves").
