Product description
Eccentric press mode
Eccentric presses must not be allowed to stop at the bottom dead centre because their
c
onstruction 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 26.
The muting can only be activated once per machine cycle.
Protect the machine during the mute state!
In eccentric press mode, you must take suitable measures to ensure that no dangerous
state can occur while muting is active.

of the operating mode, file card General, option Eccentric press mode active.
In eccentric press mode with release mode “not limited”, the safety light curtain only de-
tects an interruption during the total muting time as PSDI, if the interruption lasts longer
than the time it takes to reach the machine cycle contact for the top dead centre
(MCC>TDC).
3.3.3 Teach-in
The configurable Teach-in function has been realized in the safety light curtain C4000 and
explained in the appropriate operating instructions. The electrical connection of the teach-
in key-operated switch on the UE402 is described in chapter 5.4 “Teach-in key-operated
switch” of this document on page 26.
