Safety
The electronics of the EOS is specially designed,
tested and certified to perform safety relevant
functions according EN81.
Safety relevant functions of the electronics are
internally checked periodically. In the unlikely case
of an internal error this is signalized by a flashing
CHANGE UNIT-LED (see chapter 4.3.10) immediately.
At the next stop of elevator-movement, the safety
circuit will be opened to get the elevator out of
order to avoid insecure operation.
After an internal error of the EOS governor check
the supply voltage and apply the RESET signal. This
resets the internally stored error-information.
Follow the test procedure described in chapter 4.5.
When the error arises again, change the unit.
The tripping values are stated on the identification
label and can not be changed.
The box protects the electronics only when
the cover is applied.
Make sure that neither dust, dirt nor water can
reach the electronics as long as the cover is
removed! Use the bushing nipples supplied with the
EOS to ensure the proper protection of the elec-
tronics when the cables are connected.
