5.2.3 I/O module default settings
The inputs and outputs of the I/O module each have default settings.
These default settings can be changed, if required, and adjusted to local
conditions.
Responses by the inputs 1 – 6 of the I/O module are recorded and displayed in
the device controller's fault memory.
Default settings apply to software version V1.10 and higher.
All digital inputs and outputs can be set freely as option. The
setting is carried out by Reflex Customer Service, 13.1 "Reflex
Customer Service", 49

5.3 Replacing the fuses
Risk of serious injury or death due to electric shock. Some parts of the main
board may still carry 230 V voltage even with the device physically isolated
from the 230 V power supply.
• Before you remove the covers, completely isolate the device controller
from the power supply.
• Verify that the main circuit board is voltage-free.
Fusing is provided on the I/O module's main circuit board.
