2.8.9 Optical fibre sensors before and after the vacuum chamber
Fig. 2-55 Optical fibre sensors at the vacuum
chamber
Fig. 2-56 Optical fibre sensors at the vacuum
chamber
Optical fibre sensors are located be-
fore and after the vacuum chamber.
These optical fibre sensors are used
for PC board identification.
The specified as-is value of these
sensors is 4 000 digits (shown in
red).
Rehm Thermal Systems techni-
cians preset the switching threshold
to 2 700 digits (shown in yellow).
The PC board will be detected when
the threshold level is exceeded.
The contamination level is given as
a percentage. An alarm will in addi-
tion be triggered in the display
should this approach the threshold
level.
To continue proper operation, the
sensor should then be cleaned as
soon as possible, using an appropri-
ate cleaning agent.
The settings are based on Rehm
Thermal Systems experience.
