Safety guidelines 2- Muting_Sicherheit_Sicherheitshinweise
 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-equiv-
alent sensors.
WARNING!
The following information must be heeded! Failure to comply
with these guidelines could result in serious injury or death.
