Configurable functions
4.3.8
Eccentric presses
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. If you use the
1-PSDI
(eccentric presses)
or
2-PSDI (eccentric presses)
function module in your application, the
UE 470 mutes the protective field function in this phase. The muting begins when the
machine cycle contact for the bottom dead centre (BDC) 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.
If you use the
1-PSDI (eccentric presses)
or
2-PSDI (eccentric presses)
function module in
your application, you must also connect the machine cycle contact for the bottom dead
centre (BDC).
Protect the machine during the mute state!
If you use the
1-PSDI (eccentric presses)
or
2-PSDI (eccentric presses)
function module in
your application, you must ensure that dangerous states cannot arise by taking suitable
measures while muting is active.
Observe EN 963 when executing the BDC.
4.3.9
PSDI signal lamp
You can configure a PSDI signal lamp within the pin assignment for the UE 470. The
connected signal lamp illuminates if a PSDI (interruption in protective field) is expected.
The electrical connection of the PSDI signal lamp is described in Chapter 6 "Electrical
installation" on Page 56.
4.4
Evaluation of device-specific EFI status bits
The device-specific EFI status bits of the connected EFI devices can be evaluated or
stimulated directly in the UE 440/470. Thus, for example, monitoring cases in the S 3000
can be changed over through the stimulation of the specific input bits of the S 3000 via
EFI.
The meaning of the individual EFI status bits is described in the document "Status
information at the EFI connection".
Ensure that the machine safety is guaranteed at all times!
If you want to stimulate the input bits of the connected EFI devices or link the output bits,
you have to ensure that the machine safety is guaranteed at all times.
Have a check of the protective device carried out by qualified personnel (see
Section 8.3.2 "Regular inspection of the protective device by qualified personnel" on
page 76).
You can configure in the element wizard of the EFI input and output symbols which signals
are to be used by the EFI device.
Context menu device symbol UE 440/470, command Edit configuration draft… in Edit
configuration draft window, context menu element symbol of the sensor [connected EFI
device (e.g. C 4000)], command Element wizard….
