system performs a comprehensive cyclical self
test during operation. While doing so, the system identifies all states
that deviate from normal operation and enters corresponding mes
-
sages in the log book (information or error message).
With the aid of the log book, you can call up instructions on how to clear
the error directly on the terminal. The log book is described in detail in
section 4.6 M
ESSAGES AND LOG BOOK
.
10.2 Diagnosing faults in the voltage supply
10.2.1 Options for checking the voltage
The following options are available for checking the correct voltage
supply of the individual components:

Checking the log book entries
Log book entries can only be generated by components with a pro
-
cessor (e.g. IQ sensors and MIQ output modules). The log book
entries contain information on how to clear errors. For more details
on the log book, see section 4.6.

Checking the LED status on the MIQ module housing
This check is described within the framework of the commissioning
in section 3.10.3 C
HECKING THE VOLTAGE SUPPLY
.

Measuring the voltage on the MIQ modules
(see section 10.2.2 M
EASURING THE VOLTAGE
).
Information on possible errors in IQ sensors and
MIQ output modules is given in the chapter W
HAT TO DO IF
... of the respective component operating manual.
The relationship between the supply voltage, the LED sta

tus and the log book entries is described in the section
