CD IEC 5.5.1: .. an indicator to show when the muting function is active can be necessary.
62046/Ed. 1:
The muting function shall be initiated and terminated automatically....Incorrect sig-
2005
nals, sequence, or timing of the muting sensors or signals shall not allow a mute
condition. It shall not be possible to initiate the muting function when:
– the protective equipment OSSDs are in the OFF-state;
– the protective equipment is in the lock-out condition.
- initiation of the muting function by two or more independent muting sensors such
that a single fault cannot cause a muted condition;
- termination of the muting function by two or more independent muting sensors
such that deactivation of one sensor will terminate the muting function;
- use of timing and sequence control of the muting sensors to ensure correct muting
operation;
5.5.3: The following measures shall be considered:...
- limiting muting to a fixed time that is only sufficient for the material to pass through
the detection zone. When this time is exceeded, the muting function should be can-
celled and all hazardous movements stopped;
Annex F.3 Four beams - sequence control: (see also Fig. F.3.1 and table F.1)
The initiation of the muting function depends on monitoring the correct sequence of
activation of the muting sensors. For example, in the muted condition, if S2 [in this
document MS_12] is deactivated before S3 [in this document MS_21] is activated,
muting is terminated.
Annex F.5: Methods to avoid manipulation of the muting function: ... use a muting
enable command generated by the control system of the machine that will only en-
able the muting function when needed by the machine cycle.
