Functions
Leuze electronic MSI-MD-FBX 14
4 Functions
By means of muting, the protective function of the safety sensor can be temporarily and properly sup-
pressed, e.g. if objects are to be transported through the protective field. The OSSDs of the muting con-
troller remain in the ON state in spite of interruption of one or more beams of the safety sensor.
Muting mode
The muting controller supports the following muting mode:
• Timing controlled 2-sensor muting (see chapter 4.1 "Timing controlled 2-sensor muting")
Muting timeout
Configurable time limit for the muting function (muting timeout):
• 20seconds
• 2minutes
• 10minutes
• 100hours
Muting timeout is set via the DIP switch blocks (see chapter 8 "Starting up the device - Configuration").
Muting sensors
Muting is initiated automatically and via mutually independent muting signals by muting sensors.
• Photoelectric sensors or scanning sensors can be connected to the muting controller as muting sen-
sors (see chapter 14 "Order guide and accessories").
• The state of a muting sensor is transferred on pin4 of the connection on the muting controller.
• The muting signals of the muting sensors are debounced:
• Pickup delay: 60ms
• Slow release: 300ms
NOTICE
Do not use muting signal MS1 via machine interface and local socket simultaneously!
ÄIf muting signal MS1 is used via the machine interface, MS1 must not be used simultane-
ously on the local socket.
4.1 Timing controlled 2-sensor muting
Muting is initiated automatically and via two mutually independent muting signals. These signals must be
active during the entire duration of the muting operation. Muting may not be initiated by a single sensor sig-
nal, nor may it be fully initiated by software signals.
The protective function of the entire protective field is deactivated during timing controlled muting.

The material can move in both directions. Often, an arrangement consisting of crossed beams from retro-
reflective photoelectric sensors is used (see chapter 6.2 "Arrangement of the muting sensors").
Timing controlled muting is used in the following cases:
• Moving-in applications: diffuse sensors in the danger zone detect the muting object through the protec-
tive field. The scanning range must be set to a sufficiently small value (see chapter 6 "Mounting").
• Exit applications: a photoelectric sensor in the danger zone works diagonally to the transport direction
together with a simultaneously activated machine interface signal, which derives from the drive of the
transport equipment, for instance (see chapter 6 "Mounting").
DANGER
Risk of death if installation is not performed correctly!
ÄFollow the instructions for the correct arrangement of the muting sensors (see chapter 6.2
"Arrangement of the muting sensors").
4.1.1 Timing controlled 2-sensor muting with Muting-enable
With the muting enable function, muting is enabled or disabled via an external muting enable signal. The
muting enable function is activated and deactivated via the DIP switch blocks (Starting up the device - Con-
figuration).
• If the muting enable signal is applied, a valid muting sequence initiates muting.
The muting enable signal must be applied at least 60ms before muting is initiated.
The muting enable signal must not be applied for more than 100hours.
• If the muting enable signal is not applied, no muting is possible, even with a valid muting sequence.
4.2 Overriding and muting restart
Following malfunctions or operationally related interruptions (e.g. power failure, violation of the simultaneity
condition during timing controlled 2-sensor muting on activation of the muting sensors), the system can be
manually reset with the acknowledgment unit and overridden.
• Muting override must only be initiated if at least one muting sensor is activated and the OSSDs of the
muting controller are switched off.
• Muting override is maintained only if at least one muting sensor is activated.
• The muting controller switches on its OSSDs when muting override is activated.
• For muting override or muting restart, the maximum muting timeout time is 10minutes.
Functions
Leuze electronic MSI-MD-FBX 16
WARNING
Unauthorized muting restart may result in serious injury!
ÄA qualified person (see chapter 2.2 "Necessary competencies") must observe the procedure
exactly.
ÄMake certain that the danger zone can be viewed from the acknowledgment unit and that
the entire process can be observed by the responsible person.
ÄBefore and during the muting restart, ensure that there are no people in the danger zone.
NOTICE
If the safety sensor or the muting controller responds with an error message, perform an error
reset (see chapter 4.3 "Error reset").
ÄPress and release the acknowledgment unit within 0.2 to 4s.
ÄPress the acknowledgment unit again and keep the acknowledgment unit pressed down.
ðThe muting controller switches on.

Muting is initiated when the acknowledgment unit is released. The second muting signal must be activated
within a maximum of 4s in order to continue muting. If the second muting signal is not activated within this
time, muting is ended.
No muting signal is activated:
Muting is ended immediately even if the acknowledgment unit is not released.
Muting controller with muting enable; a muting signal is activated:
Muting is initiated when the acknowledgment unit is released. The second muting signal must be activated
within a maximum of 4s in order to continue muting. If the second muting signal is not activated within this
time, muting is ended.
Muting controller with muting enable; without extension of the muting timeout:
Overriding is only possible with acknowledgment unit permanently pressed down.
4.3 Error reset
If an internal or external error is detected by the safety sensor or the muting controller, the muting controller
switches to the interlock state.
To reset the safety circuit to the initial state, reset the muting controller via the reset signal.
• The reset signal can be set via the connected acknowledgment unit or via a component in the machine
interface.
• When overriding, the reset signal may only come from one source, i.e., either from the connection
socket of the acknowledgment unit or from the RES signal of the machine interface.
• Duration of the reset signal: 0.2s to 4s
Manual error reset
Reset signal via the connected acknowledgment unit
ÄPress and release the acknowledgment unit within 0.2 to 4s.
Functions
Leuze electronic MSI-MD-FBX 17
4.4 Restart
Following a violation of the protective field, the OSSDs are re-enabled via the reset signal.
• The restart can be started manually via the connected acknowledgment unit or via a component in the
control (Starting up the device - Configuration).
• The reset signal can be set via the connected acknowledgment unit or via a component in the machine
interface.
• Duration of the reset signal: 0.2s to 4s
4.5 Acknowledging/resetting
The ReadyForReset signal signals via the RES LED that the system is waiting for actuation of the acknowl-
edgment unit/reset button.
• The RES LED illuminates red if the OSSDs of the safety sensor are switched on and
the OSSDs of the muting controller are switched off.
• The RES LED flashes red if the system is expecting a muting restart, depending on the status of the
muting sensors. The OSSDs of the safety sensor must be switched off.
• The RES LED flashes red if a muting error occurs.
• If a muting error occurs together with a protected field violation, the OSSDs are switched off when
muting is terminated.
• If a muting error occurs in a free protective field, the OSSDs remain switched on.

6.2 Arrangement of the muting sensors
Muting sensors detect material and supply the signals necessary for muting. Standard IEC/TS62046 pro-
vides basic information on arranging the muting sensors. This information must be observed when mount-
ing the muting sensors.
WARNING
Improper installation may result in serious injury!
If the distance between transmitter and receiver is larger than the width of the object so that
gaps of more than 180mm are created, suitable measures, e.g. through additional guarding,
must be taken to stop the dangerous movement before persons enter the area.
ÄMake sure that no persons can reach the danger zone alongside the transport material dur-
ing muting.
ÄMake sure that muting is only temporarily activated and only as long as the access to the
danger zone is blocked by the transport material.
NOTICE
If accessible distances exist between the transport material and the safety sensor, PS mats or
wicket gates monitored with safety switches have been tried, tested and proven as additional
safeguards. Such measures prevent injuries caused, for example, by crushing in the access
area.
