Hardware Configuration; Limits Of Use - Pfannenberg PMF 2015-SIL Instructions De Service

The 'proof test' is to be carried out as follows:
Test Test step
Product life a.) Performed operating
hours
Visual check b) Housing
c) Light emission
d) Cable screw joint
e) Condensed water
Function f) Manual function test
g) Flash frequency
Logging h) Logging of the test
results
The check whether the function test is correctly evaluated via the superior control system is dependent on
the use and must be defined by the installer/operator.
Should faults occur with the flashing light or the flashtubes and flash capacitors come to the end of their life,
please proceed as described in section 4.18.

4.11. Hardware configuration

No adjustments to the hardware are necessary or possible.

4.12. Limits of use

The limits that can be taken from the technical data in section 3 are to be kept.
The limits for the calculation of the safety integrity of the light in systems is to be taken from section 4.4.
Before being put into service, the time at which the lifetime of 8 million flashes is reached is to be calculated.
At this point a replacement of original parts is necessary (see also section 'Proof test'). That is to be integrat-
ed in the respective operating documents.
Changes to the light are only possible via the manufacturer. The safety parameters must be recalculated and
the functional safety must be tested. Changes by the user are not allowed and lead to voiding of the warran-
ty.

Test instruction
The flashtubes and the corresponding flash capacitors have reached
their planned end of life after approx. 8 million flashes. That corre-
sponds to approx. 2200 operating hours of the flash generating
channel. After expiry, the the flashing lights or both the components
must be replaced by original parts.
mechanical damage, corrosion damage, attachment to the location
not covered or dirty
tight fit, seal for the cable guaranteed
no condensed water in inner part of the light
Step-by-step carrying out of the function test as described in section
4.7. Check the switching status of the contacts of the alarm relay and
its correct evaluation via the superior control system
the number of flashes per minute is to be determined upon activation
of the flashing light. A visual check can take place with the help of a
stop watch. 55 to 65 flashes must be generated per minute.
must comply with the rules for functional safety according to
