3.4. Operation mode (low/high demand mode)
The safety functions of the actuators supplied by AUMA are suitable for the low
demand mode and may only be used in this operation mode. If a non-safety
instrumented function of basic process control system is executed via the same
actuator in addition to the safety function, note that while considering the sum of
non-safety instrumented function, required tests and safety function, the defined
number of maximum permissible cycles
1)
for the respective actuator as well as the
maximum number of starts
2)
may not be exceeded during deployment of the actuator
within a safety instrumented system.
Only the “safe end position feedback” safety function can be operated beyond
the limitations mentioned above under certain conditions even in operation mode
with high demand rate, provided the following requirements and limitations are
heeded:
●
When considering the sum consisting of non-safety instrumented function, re-
quired tests and safety function, the number of maximum cycles of the actuator
end position switches as well as the maximum number of starts during actuator
deployment are not exceeded in a safety instrumented system.
●
When considering the sum consisting of non-safety instrumented function, re-
quired tests and safety function, the number of maximum cycles for the respect-
ive actuator as well as the maximum number of permissible cycles
1)
or starts
2)
are not exceeded, if appropriate scaling rules are applied.
●
Lubrication is checked at regular intervals and the lubricant changed if required,
however, at least every 10 years.
●
Every 20,000 cycles
1)
or starts
2)
(whatever occurs earlier), the crown wheel and
the worm wheel are checked for wear and replaced if required.
●
The end user makes sure that a test rate (PVST) is achieved for the “Safe end
position feedback” safety function, complying with the demand rate to be expec-
ted according to the applicable standards for the respective application.
●
All requirements in accordance with the “Technical data for switches” (Y004.619)
data sheet are respected. In particular, the permissible minimum and maximum
currents and voltages.
●
The number of cycles
1)
as well as the number of cycles of each limit and torque
switch do not exceed the values stipulated in the table below:
