Automatic start
In automatic start mode, the machine-release contacts K1 and K2 are
energised as soon as the auto-start programmed AOPD is free after an
intrusion
k
in its protective screen. This requires that the other AOPDs
that are set for manual start are not interrupted.
Manual start
In manual start mode, the machine-release contacts K1 and K2 are only
energised when the manual-start programmed AOPD is free after an in-
trusion in its protective screen and the start button has been pressed
l
.
The start button must be activated on 2 conditions:
After return of the supply voltage

mutinG (byPass)
Muting means to temporarily disable the protective function of an AOPD.
This function is used to transport material through an AOPD without stop-
ping the machine. The differentiation between material and persons is
achieved by using additional muting sensors (MS). Together with the
AOPD, these muting sensors have to generate a precise switching se-
quence in order to launch a muting cycle that allows the material to pass
the AOPD without stopping the machine. The muting control then starts
the muting cycle for the time the material is passing the AOPD. It must
not be possible that a person activates the muting sensors in the same
switching sequence as the material. To realise this function, different
switching sequences can be chosen on yrB-0330-242 either with 2 or 4
muting signals. This makes sure that if a person passes the AOPD, the
dangerous movement of the machine is stopped immediately. The muting
cycle is indicated by means of a muting lamp. The maximum muting time
can be set in 10 steps between 10 s and infinite. If the AOPD is still inter-
rupted after the max. permitted muting time (e.g. by blocked material) the
contacts K1, K2 open and the muting lamp as well as the LED run 1 show
function failure code 4.
Starting by pressing the start button is only possible if the muting lamp is
working properly and the AOPD to be muted is free of interruption. During
the muting cycle a wrong switching sequence or exceeding the maximum
muting time leads to function failure code 4. This failure can only be reset
by pressing the start button. The muting sensors have to be installed in a
way that the correct sequence cannot be achieved manually or by passing
the AOPD (see IEC/EN 61496-1)

oVerride
If the monitored area is blocked by transported material and the outputs
K1, K2 are switched off, this is indicated by fast flashing (approx. 3 Hz) of
the muting lamp
when activating the restart button
. The operator can
activate the outputs K1, K2 by pressing the start button for more than 3 s
for a maximum time of 12 s until the muting sensors are again inactive or
the start button is released again.
