3 Product description
3.1 Specific features
Figure 1: Flexi Classic modular safety controller
The Flexi Classic series is a safety controller concept comprising different modules
that can be interconnected individually. This allows the system to be extended to up to
104inputs or outputs.
Each of these modules has a compact width of 22.5mm. The units are of plug-in style
with communication between the individual units over an internal bus.
The required logic and function is specified by means of rotary switches on the mod‐
ules. An exception thereof are the relay modules and the fieldbus modules that are
used for integration in a higher level controller without a safety function. These modules
are output units and have no effect on the logic set or the function of the upstream
units.
The Flexi Classic series consists of the following modules:
•Main module UE410-MU
•Main module UE410-GU
•Input/output extension module UE410-XU
•Input expansion module UE410-8DI
•Output modules UE410-2RO and UE410-4RO
•Gateways, e.g.
– UE410-PRO (PROFIBUSDP)
– UE410-DEV (DeviceNet)
– UE410-CAN (CANopen)
– UE410-EN1 (EtherNet/IP)
– UE410-EN3 (Modbus® TCP )
– UE410-EN4 (PROFINET IO)

Figure 2: Flexi Classic safety controller system construction (example with UE410-MU)
3.2.1 Main module UE410-MU
The UE410-MU is the main module in which the system configuration of the entire Flexi
Classic system is stored.
The UE410-MU has 4 safety inputs, 4 semiconductor outputs and 2 test outputs. The
9 programs that are available can be set by means of rotary switches that ensure the
connection of a large number of safety components. Functions such as EDM, restart,
etc. are selected by means of the wiring of S1, S2 and S3. The UE410-MU can control
two applications acting independently as well as two applications that are dependent
on each other.
The devices listed in the following can be connected to the UE410-MU and the modules
connected to it:
•Emergency stop pushbutton
•Pressure sensitive mats
•Two-hand controllers
•Safety switches
•Non-contact safety switches (e.g. RE300, T4000 Compact, IN4000)
•Safety single-beam sensors (e.g. L21, L41)
•Safety light curtains and safety multibeam sensors (e.g. MSL, miniTwin, C/M2000,
C/M4000)
•Safety laser scanners and safety camera sensors (e.g. S300, V300, S3000)
Typical applications such as muting and OR links can be implemented simply, depend‐
ing on the setting of the program switch. If additional inputs or outputs are required,
the UE410-MU can be supplemented with a UE410-XU input/output expansion module
and/or one or several UE410-8DI input expansion modules.
If relay outputs are required, these can be implemented with the UE410-2RO/
UE410-4RO output modules.
3.2.2 Main module UE410-GU
The UE410-GU is a main module that can be used as an alternative to the UE410-MU.
As in the UE410-MU, the system configuration for the entire Flexi Classic system is
saved in the UE410-GU. The UE410-GU makes possible a global emergency stop
function for several stations connected together that must each be equipped with a
UE410-GU. A local emergency stop is also possible on each UE410-GU.

14 O P E R A T I N G I N S T R U C T I O N S | Flexi Classic 8011509/1IWE/2023-05-17 | SICK
Subject to change without notice

The UE410-GU has 4safety capable inputs (I1-I4), 1semiconductor output (Q1), 1out‐
put for a lamp for “Global emergency stop status” and “Reset required” (Q2), 2test
outputs (X1, X2) and 2inputs and 2outputs for the global emergency stop function (IP,
IN, OP and ON). The safe control inputs I5 and I6 are used to connect external device
monitoring and a reset button. The 9available programs can be set using a rotary
switch and make it possible to connect a variety of safety components.
The following devices can be connected to the UE410-GU:
•Emergency stop pushbutton
•Interlock safety switch
•Non-contact safety switches (e.g. RE300, T4000 Compact)
•Safety single-beam sensors (e.g. L21, L41)
•Safety light curtains and safety multibeam sensors (e.g. MSL, miniTwin, C/M2000,
C/M4000)
•Safety laser scanners and safety camera sensors (e.g. S300, V300, S3000)
If additional inputs are required, the UE410-GU can be supplemented with one or more
UE410-8DI input expansion modules.
The UE410-GU can also be expanded with a UE410-XU. This module does not act on
the global emergency stop.
If relay outputs are required, these can be implemented with the UE410-2RO/
UE410-4RO output modules.
NOTE
The UE410-GU does not support all data sets from all gateways.
3.2.3 Input expansion module UE410-8DI
The UE410-8DI module is an input expansion with 8inputs that can be linked using the
OR, AND or Bypass logic function to the respectively upstream UE410-MU, UE410-GU
or UE410-XU module. The 9switch settings of the UE410-8DI rotary switch determine
which safety components can be connected to the UE410-MU/GU/XU and which type
of logic is used. The input expansion module UE410-8DI acts exclusively on the next
UE410-MU, UE410-GU or UE410-XU module positioned to the left in the module struc‐
ture, thus forming a function group. It is allowed to connect a maximum of 8 UE410-8DI
modules to a UE410-MU, UE410-GU or UE410-XU.
For more information, see "Grouping of subsystems", page 75.
3.2.4 Input/output extension module UE410-XU
The UE410-XU module is an input/output expansion module with 4safety capable
inputs, 4semiconductor outputs and 2test outputs. It has the same switch settings,
logic functions and facilities for connecting sensors as the UE410-MU. In contrast to
the UE410-MU and UE410-GU, the UE410-XU cannot store the system configuration.
NOTE
•A UE410-XU can only be operated in combination with a UE410-MU or UE410-GU
main module.
•A main module and a UE410-XU can be linked logically with each other, thus form‐
ing a subsystem (for further information see section "Grouping of subsystems",
page 75.

3.2.5 UE410-2RO/UE410-4RO output modules
The UE410-2RO/UE410-4RO output extensions make one or two dual-channel, con‐
tact-based outputs available. They do not have any influence on the specified logic
instructions of a system construction and are controlled by the UE410-MU, UE410-GU
or UE410-XU outputs.
3.2.6 Gateways
Gateways (fieldbus modules) can be added to the Flexi Classic modular system for
diagnostic purposes. They output the system configuration and the input/output states
as well as the error and status information of all the modules.
Several gateways are available, e.g.:
•UE410-PRO for PROFIBUSDP
•UE410-DEV for DeviceNet
•UE410-EN1 for EtherNet/IP
NOTE
The UE410-GU does not support all data sets from all gateways.
You will find a complete list of all gateways and the data sets supported in the operating
instructions “Flexi Classic Gateways” or in the Internet on our homepage www.sens-con‐
trol.com.
All gateways have 4non-safe application diagnostic outputs. The outputs are short-cir‐
cuit protected (see also the Flexi Classic Gateways operating instructions).

3.3 Main module UE410-MU
The UE410-MU main module is the main module of the Flexi Classic modular safety
controller. Only one UE410-MU can be integrated for each Flexi Classic system. A
UE410-MU can control up to two applications acting independently or two applications
that are dependent on each other.
In order to increase the number of inputs, one or more UE410-8DI extension modules
can be used additionally.
An additional UE410-XU module can be used in order to increase the number of
outputs (for further information refer to "Grouping of subsystems", page 75).
The system configuration is stored in the UE410-MU main module (ENTER pushbutton
to accept the program settings and system configuration) (for further information refer
to "Accepting the system configuration", page 87).
9programs that can be set with a screwdriver at the program switch are available.

ing on the device variant 0-5s; 0-50s; 0-300s; not on UE410-xxxT0).
NOTE
The outputs are tested periodically in order to detect errors in the safety outputs Q1-Q4.
When using XU modules see section "Grouping of subsystems", page 75
For more information, see "UE410-MU/UE410-XU programs", page 36.
NOTE
Subsequent changes to the program or to the wiring (S1-S3) without saving will result in
a safety-related shutdown.
