Standards Requirements
IEC 60204-1, 9.2.6.3: Enabling control (refer also to 10.9 below) is a manually activated control function
Ed. 5.0:2003 interlock that:
●
●
Enabling control shall be so arranged as to minimize the possibility of defeating, for
example, by requiring the deactivation of the enabling control device before machine opera-
tion may be reinitiated. It should not be possible to defeat the enabling function by simple
means.
10.9: When an enabling control device is provided as a part of a system, it shall signal the
enabling control to allow operation when actuated in one position only. In any other position,
operation shall be stopped or prevented.
Enabling control devices shall be selected that have the following features: ...

State name State description and output setting
Muting Start Muting sequence is in starting phase after rising trigger of
2 S_MutingSwitch12. Monitoring of DiscTimeEntry is activated.
Ready = TRUE
S_AOPD_Out = TRUE
S_MutingActive = FALSE
Error = FALSE
Muting Muting sequence is active either:
Active
- After rising trigger of the second S_MutingSwitch 12 or 11 has
been detected.
- When both S_MutingSwitch 11 and 12 have been actuated in
the same cycle.
Monitoring of DiscTimeEntry is stopped. Monitoring of
MaxMutingTime is activated.
Ready = TRUE
S_AOPD_Out = TRUE
S_MutingActive = TRUE
Error = FALSE
when activated allows a machine operation to be initiated by a separate start control,
and
when deactivated - initiates a stop function, and - prevents initiation of machine opera-
tion.
for a three-position type:
– position 1: off-function of the switch (actuator is not operated);
– position 2: enabling function (actuator is operated in its mid position);
– position 3: off-function (actuator is operated past its mid position);
when returning from position 3 to position 2, the enabling function is not activated.
