Modular Block System: Hydraulic Presses 6-99
“Muting OFF”
The switch condition for “Muting OFF” is fulfilled when muting signals MP1
and MP2 are reactivated.
“Muting Start-Up”
Muting signals MP1 or MP2 must be operated if a vehicle is within the
range of the ESPE/AOPD.
Safety guidelines
WARNING!
The following information must be heeded!
Failure to comply with these guidelines could result in serious injury or
death.
• Refer to EN 61 496-1, 06/98 when setting parameters for SB072 and
when designing and operating the muting facility.
• Muting switches should be positioned so that it is impossible for a person
to trigger the muting function.
• The transport 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 measures.
People must not be able to enter the danger area during the muting
phase.
• Consider the total duration of the muting phase if various transport
speeds are to be in operation.
• Remember that a new muting phase can only be introduced once the
previous phase has been completed.
• Maintenance gates should be provided if equipment is protected via a
muting signal.
Remember that the plant must be brought to a stop if the maintenance
gates are opened.
• Using muting signals provided by switch contacts
These contacts should use test pulses.
• Using sensors as muting signals MP1 and MP2
Pulsing is not possible when using sensors. For fault detection,
therefore, you should use a N/O contact as sensor MP1 and a N/C
contact as sensor MP2.
