Leuze electronic MSI-MD-FBX 38
Error Cause/description Remedies and measures Behavior of the
muting controller
U35 Sequence error if muting sen-
sor 3 and muting sensor 4 are
activated and muting sensor 3
should be free Check the arrangement and align-
ment of the muting sensors Automatic reset
U41 Concurrency expectation of
the muting signals not met:
second signal outside toler-
ance of 4 s Check the arrangement of the mut-
ing sensors or the programming of
the machine interface if required. Automatic reset
U43 Muting end before protective
field release Select a valid muting condition. Automatic reset.
U44 Sequence error if muting sen-
sor 1 and muting sensor 2 are
activated and muting sensor 2
should be free Check the arrangement and align-
ment of the muting sensors Automatic reset
U45 Sequence error if muting sen-
sors 1 to 3 are activated and
muting sensor 3 should be free Check the arrangement and align-
ment of the muting sensors Automatic reset
U46 Sequence error if all muting
sensors are activated and mut-
ing sensor 4 should be free Check the arrangement and align-
ment of the muting sensors Automatic reset
U47 Sequence error between mut-
ing sensor 2 and muting sen-
sor 1 Check the arrangement and align-
ment of the muting sensors Automatic reset
U48 Sequence error between mut-
ing sensor 3 and muting sen-
sor 2 Check the arrangement and align-
ment of the muting sensors Automatic reset
U49 Sequence error between mut-
ing sensor 4 and muting sen-
sor 3 Check the arrangement and align-
ment of the muting sensors Automatic reset
U50 Muting restart without valid
muting configuration of the
muting sensors Check the mounting of the muting
sensors and the activation of the
muting signals. Automatic reset
U51 Only one muting signal active
in case of protective field viola-
tion, the second muting signal
is missing Check the mounting of the muting
sensors and the activation of the
muting signals. Automatic reset
U52 Oscillating muting sensor de-
tected Check the wiring or whether the
muting sensor is defective. Ex-
change the muting sensor if nec-
essary. Automatic reset.
U55 Time limit for override ex-
ceeded Check the further processing of
the OSSD signals and the design
of the muting system. Automatic reset
U56 Acknowledgment unit was ac-
tuated with interrupted protec-
tive field and without activated
muting sensor Check the arrangement and con-
nections of the muting sensors and
carry out muting restart again if re-
quired. Automatic reset
U58 Muting timeout elapsed Actuate the acknowledgment unit Automatic reset
U59 A muting sensor has switched
on and off again multiple times
without muting having been
triggered Check the arrangement and align-
ment of the muting sensors. Automatic reset
