2.2.1 Intended use

Intended use2-Muting_Sicherheit_Bestimmungsgemäße Verwendung

The muting logic element is used to temporarily suspend safety func­tions (ESPE/AOPD) without interrupting the process (muting) in accord­ance with EN 61496-1. For a limited time period and a specific
operational phase (e.g. when feeding materials), it will suspend the ef­fect of safety devices during the working process. Once completed, it
will reset the safety function.

Use of this operating mode and the arrangement of the sensors are ma­chine or plant-specific and depend on the risk assessment of the ma­chine or plant.

Be sure that you observe the warning notes given in the other parts of
this configuration guide and in the PNOZmulti technical catalogue.
These are highlighted visually through the use of symbols.

2.2.2 Standards

Standards2-Muting_Sicherheit_Normen

CAUTION!

Failure to observe the safety regulations in this configuration
guide and in the PNOZmulti technical catalogue will render the
warranty invalid.

Knowledge of and compliance with the relevant standards and direc­tives are a prerequisite for using the muting function. The following gives
an overview of the most important standards:

 EN 61496-1: Safety of machinery – Electrosensitive protective equip-

ment

 EN 60947-5-3: Low voltage switchgear and controlgear - Control cir-

cuit devices and switching elements

 EN 999: Safety of machinery - The positioning of protective equip-

ment

Please note this is not an exhaustive list of safety standards and direc­tives.

2.2 Safety

2.2.3 Safety guidelines

Safety guidelines2-Muting_Sicherheit_Siche rheitshinweise

WARNING!

The following information must be heeded! Failure to comply
with these guidelines could result in serious injury or death.

 Refer to EN 61496-1 and EN 60947-5-3 when configuring, setting up

and operating the muting device.

 Refer to EN 999 with regard to the positioning of the AOPD.
 Measures must be taken to exclude common cause failures, e.g. by

the use of non-equivalent signals or diverse sensors.

 Muting switches should be positioned so that it is impossible for a

person to trigger the muting function.

 The vehicle should be designed to make it impossible for people to

ride on it.

 Limit the size of the entry area by applying appropriate safety meas-

ures. People must not be able to enter the danger zone during the
muting phase.

 If various transport speeds are being used, consider the total duration

of the muting phase.

 Remember that a new muting phase can only be introduced once the

previous phase has been completed.

 Maintenance gates should be provided if you secure equipment

through muting.

 Please note that if the maintenance gates are opened, the plant ab-

solutely must be brought to a standstill in accordance with the risk

classification.

 Use of muting sensors with contacts: Supply the contacts of the mut-

ing sensors via test pulse outputs (test pulses).

 Use of ESPE as muting sensors: Test pulses cannot be used. For this

reason, be sure to use a N/O contact as sensor 1 and a N/C contact
as sensor 2 for fault detection (shorts across contacts).

 Laying the connection cable to the sensors in a way that is protected

against shorts (i.e. separate) may provide an alternative to non-equiv­alent sensors.

2.3 Configuration in the PNOZmulti Configurator

CAUTION!

The following additional safety requirements apply to the muting
override:

– The override switch must have a hold-to-run control device

(touch-operated switch).

– The override switch must be installed in a fixed position out-

side the danger zone.

– The danger zone and the muting station must be visible

from the override switch position.

– The danger zone must be identified as clear before the over-

ride switch is operated and while it is operated.

2.3.6 Reset

Reset2-Muting_Konfiguration _Reset

Reset resets the muting element after a fault or during start-up if

 no muting sensor is operated

and

 the light curtain is clear.

2.3.7 Restarting the muting time

Restarting the muting time2-Muting_Konfiguration_Neu start der Muting-Zeit

Reset resumes muting and restarts the muting time if

 muting was ended as a result of the muting time having elapsed (e.g.

by the conveyor feed stopping)

and

 the muting sensors are returning feasible signals and the light curtain

has not been interrupted.

CAUTION!

The following additional safety requirements apply for the reset
button:

– The danger zone and the muting station must be visible

The following operating modes can be implemented:

 Sequential muting
 Parallel muting
 Cross muting

WARNING!

"During muting safe conditions shall be provided by other
means" (EN 954-1). For example, this may be achieved by the
conveyed item blocking access to the danger zone. Even open­ings in or between the individual parts of the conveyor flow must
never enable access.

2.4.1 Terminology

Terminology2-Muting_Betriebsarten_Begriffsbestimmungen

 Muting On

"Muting On" is the switch condition for switching on the muting func­tion. When muting is switched on, the

Muting active

output parame-

ter has a 1 signal and time monitoring runs.

 Muting Off

"Muting Off" is the switch condition for ending the muting function.
When the muting function is ended, output parameter

Muting active

has a 0 signal.

Muting On

Entering the danger zone:

1. Muting sensors MS1 and MS2 must be operated consecutively (first
MS1, then MS2) within the configured simultaneity period. Muting is
activated by operating MS2.

2. Muting sensors MS3 and MS4 must be operated consecutively (first
MS3, then MS4) within the configured simultaneity period.

3. MS1 and MS2 must be cleared consecutively (first MS1, then MS2).

4. MS3 and MS4 must be cleared consecutively (first MS3, then MS4).

Leaving the danger zone:

1. Muting sensors MS4 and MS3 must be operated consecutively (first
MS4, then MS3) within the configured simultaneity period. Muting is
activated by operating MS3.

2. MS2 and MS1 must be operated consecutively (first MS2, then MS1).

3. MS4 and MS3 must be cleared consecutively (first MS4, then MS3).

4. MS2 and MS1 must be cleared consecutively (first MS2, then MS1).

Muting Off

Suspension of the safety function is cancelled as soon as the penulti­mate muting sensor, MS2 or MS3, is no longer operated, i.e. only
one muting sensor remains operated.
