Function
If the semiconductor outputs of the installed safety
device (e. g. C 4000, S 3000) are energised, then the
safety output contacts will close.
When at least one of the semiconductor outputs of the
safety device becomes de-energised, then the output
contacts revert back to open circuit status.
If Restart Inhibit is needed, then this is achieved in the
safety device, for example C 4000 or S 3000.
External device monitoring (EDM)Safety Category 3 or 4 requires monitoring of
contactors. This is provided in the connected protective
device, for example in the C 4000 or S 3000. The
normally closed contact (Y 1 - Y 2) in the UE 10-3 OS
unit is, however, a part of this contactor monitoring
system.
The UE 10-3 OS 2 unit has screw type terminals.
The UE 10-3 OS 3 unit has removable terminals.

Function
The supply voltage of the expansion module is linked to
an output contact of a main unit.
Upon applying the supply voltage to terminals A 1 and
A 2, relays K 1 and K 2 are energised (the LEDs for
both relays illuminate): The 4 ouput contacts close, the
two normally closed contacts and the EDM (feedback)
circuit switch to open circuit status.
When the output contacts of the standard unit opens
(e.g. by activation of the Emergency Stop), the relays
K 1 and K 2 de-energise: The normally open contacts
open, and the two normally closed contacts close.
External device monitoring (EDM)If external device monitoring is implemented in the
connected main unit, then the normally closed contacts
(Y 1 - Y 2) prevent the resetting of the main unit, when
K 1 and/or K 2 do not de-energise.
The function of the UE 11-4 DX ...... corresponds to that of the UE 10-4 XT, but the unit
also has fixed switch off-delay times of 0.5 sec, 1 sec,
2 sec and 3 sec, depending on the model. They are
achieved by means of capacitors, so that even in the
event of power supply failure the off-delay runs its full
duration in each instance. The delay cannot be
prematurely cancelled. Only after the delay periods have
expired do the relays K 1 and K 2 return to their neutral
rest position.
With the combination of UE 11-4 DX and a main unit,
Stop Category 1 (EN 418) can be realised.
Units ... XT 2 and ... DX 2 have screw type terminals,
Units ... XT 3 and ... DX 3 have removable terminals.

UE 23-2 MF Series
Function
After applying the supply voltage (LED SUPPLY illumi-
nates), the normally open contacts remain in the open
state. If the connected sensor is not activated (i.e. the
input circuits are closed), then the normally open
contacts close immediately in Automatic Reset (LED
“K 1, K 2“ illuminate). In the case of Manual Reset,
this only occurs after pressing the Reset button.
External device monitoring (EDM)The unit can take over the function of external device
monitoring. The contactor monitoring system monitors
the external relays through their normally closed
contacts.
Manual ResetFor Manual resetting a pushbutton must be connected
to terminals Y 1 and Y 3. This Reset is monitored.
Automatic ResetFor Automatic resetting, Y 1 - Y 2 must be linked.

UE 42-2 HD Series
Function
The UE 42-2 HD unit corresponds to EN 574 Type III C.
A prerequisite for the release of the outputs is that the
two inputs (e. g. two-hand pushbuttons) are actuated
within 0.5 sec.
After applying the supply voltage to the terminals A 1 -
A 2 the LED SUPPLY illuminates to indicate that
electrical power is present. Pressing the two-hand
pushbuttons S 1 and S 2 at the same time (see Page
53 – Sample wiring diagrams) closes the two normally
open contacts. Releasing even one of the buttons will
cause the circuits to adopt the open circuit status.
A renewed attempt to initiate starting is only possible if
both Start buttons are set to their nominal start position
(for two-hand pushbuttons units: if both have been
released) and the normally closed contact is closed.
External device monitoring (EDM)The UE 42-2 HD can take over the function of external
device monitoring. The normally closed contacts of the
external relays are switched in series, connected to the
terminals Y 1 - Y 2.
Automatic startThe UE 42-2 HD has an Automatic start facility.
Monitoring of simultaneous activationThe pressing of the Start buttons at the same time is
monitored. Only when both Start buttons are activated
within 0.5 sec do normally open contacts close and the
normally closed contact opens.
The UE 42-2 HD 2 unit has screw type terminals.
The UE 42-2 HD 3 unit has removable terminals.

Function
After applying the supply voltage (LED SUPPLY illumi-
nates), the normally open contacts remain in the opened
state. If the connected sensor is not activated (i.e. the
input circuits are closed), then the normally open
contacts close immediately in Automatic Reset (LED
„K 1, K 2“ illuminate). In the case of Manual Reset, this
only occurs after pressing and releasing the Reset
button. Activation of the sensor (opening of one or both
input circuits) effects the opening of the normally open
outputs.
External device monitoring (EDM)The UE 43-2 MF unit can take over the function of
external device monitoring. The contactor monitoring
system monitors the external relays by means of their
normally closed contacts.
Manual ResetFor Manual resetting a pushbutton must be connected to
terminals S 33 - S 34. Reset is monitored.
Automatic ResetFor Automatic resetting, S 12 - S 35 must be linked.
Cross circuit detectionCross circuit is detected on dual-channel wired systems if
these are wired with opposing polarity.
Monitoring of synchronisationOnly if input 2 closes by no later than 0.5 sec after input
1 do the ouput circuits close. If input 2 closes before
input 1, the monitoring of synchronisation will not be
effected, and the output circuits will close. This
monitoring only takes place in Automatic Reset.

Function
After applying the supply voltage (LED SUPPLY illumi-
nates), the normally open contacts (13 - 14 / 23 - 24)
remain open. After completion of the on-delay set on
the relay, the delay circuit (37 - 38) closes, and the
LED K 3 / K 4 illuminates. If the connected sensor is
not activated (i. e. the input circuits are closed), the
normally open contacts (13 - 14 / 23 - 24) close
immediately during Automatic Reset, the LED K 1 / K 2
illuminates, and the delay circuit (37 - 38) opens (LED
K 3 / K 4 off). In the case of Manual Reset, this only
occurs after pressing and releasing the Reset button.
The activation of the sensor (opening of one or both
input circuits) effects the opening of both normally open
contacts (13 - 14 / 23 - 24), with LEDs K 1 / K 2 being
off, and a time delayed closing of the third circuit (37 -
38), with LED K 3 / K 4 illuminating.
External device monitoring (EDM)The unit can take over external device monitoring. The
contactor monitoring system monitors the external
relays by way of their normally closed contacts.
Manual ResetFor Manual resetting, a pushbutton is to be connected
between 24 V DC supply and terminal S 34. This Reset
is monitored. For applications with mechanical locking
safety switches, only channel 2 must be closed during
Manual Reset (see page 59)
Automatic ResetFor Automatic resetting S 12 - S 35 must be linked. For
applications with mechanical locking safety switches,
only channel 1 must be closed during Automatic Reset.
Cross circuit detectionCross circuit is detected on dual-channel wired systems,
if these are wired with opposing polarity.
Monitoring of synchronisationOnly if input 2 closes by no later than 0.5 sec after
input 1 do the ouput circuits close. If input 2 closes
before input 1, the monitoring of synchronisation will not
be effected, and the output circuits will close. This
monitoring only takes place in Automatic Reset.

Function
After applying the supply voltage (LED SUPPLY illumi-
nates), the normally open contacts remain open. If the
connected sensor is not activated (i. e. the input circuits
are closed), the normally open contacts close imme-
diately during Automatic resetting, LED K 1 / K 2 and
K 3 / K 4 illuminate. In the case of Manual resetting,
this only occurs after pressing and releasing the Reset
button.
The activation of the sensor (opening of one or both
input circuits) effects the opening of both normally open
contacts (13 - 14 / 23 - 24) immediately, and a time
delayed closing of the third circuit (37 - 38), with LED
K 1 / K 2 immeditely going off and K 3 / K 4 going off
later.
External device monitoring (EDM)The unit can take over external device monitoring. The
contactor monitoring system monitors the external
relays by way of their normally closed contacts.
Manual ResetFor Manual resetting, a pushbutton must be connected
to terminals S 33 - S 34. This Reset is monitored.
Automatic ResetFor Automatic resetting S 33 - S 35 must be linked.
Cross circuit detectionCross circuit is detected on dual-channel wired systems,
if these are wired with opposing polarity.
Monitoring of synchronisationOnly if input 2 closes by no later than 0.5 sec after
input 1 do the ouput circuits close. If input 2 closes
before input 1, the monitoring of synchronisation will
not be effected, and the output circuits will close. This
monitoring only takes place in Automatic Reset.
The UE 45-3 S1 2 unit has screw type terminals.
The UE 45-3 S1 3 unit has removable terminals.

Function
After applying the supply voltage (LED SUPPLY illumi-
nates), the normally open contacts remain open. If the
connected sensor is not activated or the protective field
of the connected electro-sensitive protective equipment
(ESPE) is not broken (i. e. the input circuits are closed),
then the normally open contacts close immediately in
Automatic Reset, LED K 1 and K 2 illuminate. In the
case of Manual resetting, this only occurs after pressing
and releasing the Reset button.
The activation of the sensor or incursion into the
protective field of the non-contact safety device (open
state of one of the two input circuits) effects the
opening of the normally open contacts (LED K 1 and
K 2 off).
External device monitoring (EDM)The unit can take over external device monitoring. The
contactor monitoring system monitors the external
relays by way of their normally closed contacts.
Manual ResetFor Manual resetting, a pushbutton must be connected
to terminals S 33 - S 34. This Reset is monitored.
Automatic ResetFor ESPE’s: S 33 - S 35 must be linked;
for applications with potential free contacts on the input
circuit S 12 - S 35 must be linked.
Cross circuit detectionCross circuit is detected on dual-channel wired systems,
if these are wired with opposing polarity.
The UE 48-2 OS 2 and UE 48-3 OS 2 units have screw
type terminals.
The UE 48-2 OS 3 and UE 48-3 OS 3 units have
removable terminals.

Synchronisation time
Time in which a Reset button must be pressed, in order to
ensure the resetting of the safety relay.
The minimum time the inputs need to stay off in order for
the unit to recognise an off signal. Times under this value
may not be recognised as an off signal.
The unit specific minimum time the outputs must stay off.
This insures that the internal relays can fall back to their
rest state.
The minimum time the inputs need to be HIGH before a
Restart can be enabled.
The simultaneous pressing of the Start buttons is
monitored, and is specified for two-hand control systems.
Only when both safety input signals change their state
within 0.5 sec will the output contacts be switched.
Time by which the switching off of the output contacts is
delayed. This time is either fixed or adjustable depending
on module type.
Time by which the switching on of the output contacts is
delayed. For safety relays having an on-delay, the time
settings are adjustable.
Time period between the activation of the Reset and
when the ouput contacts switch on.
The time starts:
- during Manual Reset with the release of the Reset
button
- during Automatic Reset with the closing of the input
circuits (e. g. closing of the door).
The time between the activation of the inputs (e. g.
E Stop is pressed), and the switching off of the outputs.
Time, which the safety device needs after applying the
supply voltage in order to be ready for operation.
Switching of the input circuits within a fixed time span is
monitored. Only if input 2 closes by no later than 0.5 sec
after input 1 do the ouput circuits close. If input 2 closes
before input 1, the monitoring of synchronisation will not
take place, and the output circuits will close. This
monitoring occurs in Automatic Reset.
