Constraints for Use (Safety requirements for integration)
The general constraints for use of LIMAX33 CP-00 are listed here:
1.
Configuration of LIMAX33 CP-00 and the elevator (where it is installed) must fit. The configuration is not-
ed on the info sheet
7.1.2. It cannot be changed after it has once been programmed to the device. The
following topics must be taken into consideration when defining the configuration:
a.
It is possible to disable all safety functions related to inspection and/or “EN81-21”- state in com-
bination
1
. In this case neither upper resp. lower “pre-triggered stopping system”, nor upper resp.
lower inspection limit switch nor overspeed inspection (pre- /final-tripping) are performed by the
LIMAX33 CP-00. In this case these safety functions must be implemented by other means (if nec-
essary) outside of the scope of LIMAX33 CP-00.
b.
All actuators necessary for the safety functions which are enabled, must be enabled in the config-
uration and connected to the safety circuit resp. an external braking element for eSGC following
10.4.5 and
10.4.8 . Section
14.1.3 shows an overview over the
actuators necessary for the single safety functions.
c.
In case of upper resp. lower “pre-triggered stopping system” = DISABLED, it must be ensured that
there is
either ample survival space for a man on the car roof resp. in the shaft pit even if the car is
on the highest resp. lowest possible position.
or survival space for a man on the car roof resp. in the shaft pit is implemented by other
means outside of the scope of LIMAX33 CP-00.
The combination upper “pre-triggered stopping system” = ENABLED and “trip direction = only
down” is forbidden. It is also prevented by the software of the LIMAX33 CP-00 that this combina-
tion is programmed.
d.
If all safety functions related to inspection and/or “EN81-21”- state in combination are disabled,
also the upper and lower inspection limit switches are disabled. In this case must be ensured that
EN81-21 §5.5.3.4§5.7.3. resp. EN81-20 §5.12.1.5.2.1 g) are implemented by other means
outside of the scope of LIMAX33 CP-00.
e.
In case of upper or lower “pre-triggered stopping system” are enabled (not disabled) it is recom-
mended not to disable the safety function “overspeed inspection final tripping”. If “overspeed in-
spection final tripping” is disabled while upper or lower “pre-triggered stopping system” is ena-
bled, the user must ensure the worst-case speed for calculation of braking distance for pre-
triggered stopping system (refer to point
n) be other means.
f.
In case safety function “ETSL” = DISABLED, it must be ensured that
either ETSL is not needed because the buffers are designed for nominal speed of the lift
or safety function ETSL is implemented by other means outside of the LIMAX33 CP-00 scope
g.
In case safety function “final limit switches” = DISABLED, it must be ensured that safety function
“final limit switches” is implemented by other means outside of the scope of LIMAX33 CP-00
h.
Safety function “door bridging” and “UCM” can only be disabled in combination. “door bridging”
/ “UCM” = DISABLED, neither door bridging nor UCM will be performed by LIMAX33 CP-00
i.
In case safety function “over-speed final-tripping” = DISABLED, it must be ensured that
this safety function is implemented by other means outside of the scope of LIMAX33 CP-00
(usually by a conventional speed governor). In case safety function “over-speed final-tripping” =
ENABLED, safety function “over-speed final-tripping” will only fulfill EN81-20 §5.6.2.2.1.1a.) in
case the eSGC actuator is connected to a suitable (electronic triggered) safety gear. In case
“over-speed final-tripping” = ENABLED and “trip direction” = “only down”, it must be ensured
that the safety function “overspeed (final tripping)” is either not needed in upwards direction (may
be due to the construction of the lift), or that “over speed (final tripping)” in upwards direction is
secured by other means (outside the scope of LIMAX33 CP-00).
j.
The nominal speed of the LIMAX33 CP-00 must fit with the nominal speed of the lift
k.
Pre-tipping and final tripping speed must be chosen in compliancy with EN81-20 with respect to
the nominal speed.

Some, but not all of the „inspection/ EN81-21-state“- safety functions can also disabled individually
