This chapter provides information on the special features and properties of the UE 402. It
describes the construction and the operating principle of the device, in particular the dif-
ferent operating modes in connection with the safety light curtain C 4000.
Please read this chapter before mounting, installing and commissioning the device.
The functions of the UE 402 can only be used in conjunction with the C 4000 safety light
curtain Standard or C 4000 Advanced with the following entry on the type label in the field
Software version:3.00 or later.
#
The switching amplifier UE 402 extends the application possibilities of the safety light
curtain C 4000:
6operating modes are predefinable (see page 16)
PSDI mode (see page 12)
protective field evaluation bypass (see page 11)
teach-in mode: Adjusting the blanked-out areas directly on the device through the
corresponding objects in the protective field (see page 16)

The UE 402 is an electronic module. It processes certain signals of the safety light curtain
C4000 or the cascading C 4000 and merges them with the signals of other connected
systems. These systems may include:
an operating mode selector switch
ateach-in key-operated switch
akey-operated pushbutton for bypass
machine cycle contacts, e.g. for the top and bottom dead centres of a press
The UE 402 is usually installed in the control cabinet.
## '
This chapter describes the functions of the safety light curtain C 4000 which are select-
able via software, which can only be used in connection with switching amplifier UE 402.
The functions can be partially combined with the other configurable functions of the safety
light curtain.
+// ! 1
Each time the configuration is changed you must test the effectiveness of the entire pro-
tective device (see chapter titled “Test notes” in the operating instructions of the safety
light curtain C 4000).

In some applications it is at times necessary to mute the protective field evaluation of
the safety light curtain. This could be, e.g., in a safe machine setup mode, in which the
machine can be operated only at walking speed. When the bypass is active, the safety light
curtain displays Green and the 7-segment display of the receiver displays .
!5! 1
While the bypass function is active, the safety light curtain will not detect any intervention
in the protective field. You must ensure that other protective measures are forcibly acti-
vated during the bypass, e.g. the safe machine setup mode, so that the machine cannot
endanger persons or parts of the machine during the bypass function.
The bypass function may only be activated by a key-operated switch with an automatic
reset and two levels or by two input signals that are independent of each other, e.g. two
positioning switches.
It must be possible to view the entire hazardous point when pressing the key-operated
switch.
When you activate the bypass function, you can only connect a teach-in key-operated
switch (see page 24) directly to the C 4000, because the corresponding terminals of the
UE 402 are occupied by the key-operated pushbutton for bypass.
It is not possible to combine the bypass and PSDI mode functions.
The safety light curtain terminates the bypass function automatically, when …
–the operator starts a teach-in procedure.
–the operator changes the operating mode.
–there is a signal change at the Emergency Stop input on the C 4000.
– a system error (lock-out) occurs.
200 ms after switching off the bypass, the system is again in a safe status (latency time).

In the PSDI mode, the machine waits at the top dead centre for a defined number of inter-
ruptions by the operator. After a certain number of interruptions, the safety light curtain
automatically releases the dangerous movement. Dual mode PSDI means e.g., that the
safety light curtain causes the movement to block after the first interruption by the opera-
tor (). The safety light curtain does not release the movement until the operator has com-
pleted the second interruption ()().
The PSDI mode function can only be configured for light curtains with an effective opera-
ting resolution of 30 mm.

In the case of active PSDI time monitoring, the maximum duration of an entire PSDI is
limited to 30 seconds.
The 30 seconds start by the machine being stopped at the top dead centre.
When the final PSDI interruption of an entire PSDI is not terminated within this time, the
safety light curtain remains red and waits until the reset button has been pressed.
PSDI time monitoring has been configured by default and can be deactivated.

You can determine the section of the protective field in which the safety light curtain can
interpret an interruption as a PSDI. This section of the protective field is called the PSDI
window.
If you configure a PSDI window as shown in Fig. 3, the safety light curtain only interprets
as a valid PSDI interruption.
You can only define one PSDI window. This also applies to a cascading system.
At least one beam must be free between the PSDI window and adjacent blanked-out
areas.
If you do not define a PSDI window, all areas of the protective field that have not been
blanked out are PSDI windows.

To ensure that the PSDI mode operation is safe and true to the application, C 4000 in con-
nection with UE 402 evaluates three machine signals:
run-on monitoring (SCC)
Run-on monitoring evaluation is optional.
bottom dead centre (MCC-BDC)
top dead centre (MCC-TDC)
On the basis of the three machine signals, the safety light curtain can identify the
machine’s current cycle phase:
Downward movement of the press. This cycle phase involves danger.
Upward movement of the press. This cycle phase does not involve danger for all
machines.
Stopping the press. This cycle phase does not involve danger provided the “Run-on
monitoring” machine signal is not followed.
The figure below clarifies the process in time with the aid of an example of the single PSDI
mode:
aMax. 150 ms after reaching the machine cycle contact MCC-TDC, the output signal
switching devices (OSSDs) fall away.
bThe operator reaches into the protective field for at least 100 ms. The protective device
therefore recognizes the interruption as the PSDI.
cThe protective contacts close again no longer than 200 ms after the last PSDI.

You can release the PSDI control in two different ways:
Limited: The safety light curtain only evaluates interruptions within the stopping phase
as a PSDI, i.e. if the machine cycle contact was made for the top dead centre (MCC-TDC)
and has also fallen away again.
Not limited: The safety light curtain also evaluates interruptions within the upward and
stopping phases as PSDIs if the machine cycle contact is made for the top dead centre
(MCC-TDC) and has not yet fallen away again. This configuration makes higher clock
speeds possible.

If you wish to set the release of the PSDI control to Not limited,then you must make
sure at the machine side that the machine stops automatically at the top dead centre.
For this you must always observe the standards that apply for your specific applica-
tion/machine situation.

The purpose of run-on monitoring is to detect any failure of the machine brake at the top
dead centre. If you activate run-on monitoring, the UE 402 in front of the stroke release
monitors whether the SCC is still closed, i.e. whether the machine has actually stopped at
the top dead centre.
If the press exceeds the SCC before the operator has intervened once or twice depending
on the PSDI mode, the C 4000 switches to lock-out.
The SCC contact must be connected for run-on monitoring.

Eccentric presses must not be allowed to stop at the bottom dead centre because their
construction does not enable them to stop in this situation. In eccentric press mode, the
safety light curtain mutes the protective field function in this phase. The muting begins
when the machine cycle contact for the bottom dead centre is reached. You must ensure
that the machine cycle contact for the bottom dead centre is not made until after the end
of the dangerous movement. The muting ends when the machine cycle contact for top
dead centre is reached, but no longer than after 30 seconds.
When you configure the eccentric press mode you must also connect the machine cycle
contact for the bottom dead centre (MCC-BDC). The connection is described in chapter 5.5
“Machine-cycle contacts” on page 24.

In eccentric press mode, you must take suitable measures to ensure that no dangerous
state can occur while muting is active.
