Product description
3.8.2
OR link
The switch position 7 of the UE410-8DI adds inputs to the UE410-MU/UE410-XU modules
and links these with OR logic.
All input pairs are AND-linked internally. For example, only if I1 and I2 are high is the OR
signal from this pair active. If the input conditions I1/I2 or I3/I4 are logical “1”, the OR
function is active and the LED Q
A
or Q
B
is illuminated.
OR function on the UE410-GU via UE410-8DI
On the UE410-GU the OR function is only available via the UE410-8DI input extension
module (switch position 7) and only on the local cut-off path, i.e. via input B.
An OR function that acts on the global cut-off path on the UE410-GU (switch position 7,
input A on the UE410-8DI) is not permitted and will result in a configuration error (ERROR).

Bypass
The switch position 8 of the UE410-8DI jumpers the outputs of the UE410-MU/UE410-XU
modules for the maximum duration of 60 s. The bypass is only active if I1 and I2 or I5 and
I6 are logical “1”. input pairs I3/I4 and I7/I8 do not have to be wired, they have no
function.
Bypass function on the UE410-GU via UE410-8DI
On the UE410-GU the bypass function is only available via the UE410-8DI input extension
module (switch position 8) and only on the local cut-off path, i.e. via input B.
A bypass function that acts on the global cut-off path on the UE410-GU (switch position 8,
input A on the UE410-8DI) is not permitted and will result in a configuration error (ERROR).

Bypass bypasses the safety device!
It should only be possible to generate the bypass signal by means of a dual-channel N/O
key switch. The bypass should only be activated through a conscious act of the operator
and with a view of the hazardous area.
