6Product Features
LIMAX33 CP-00 is a magnetic tape-based shaft information and safety system which covers:
Several safety functions named in the EN81-20/21
The requirements regarding cab position measurement (e.g. as information for lift control)
Non safety relevant functions like door zone indication for emergency release
The magnetic measuring principle makes the sensor insensitive even to black smoke and splash water. Magnetic
tape and sensor can be mounted easily.
ADVANTAGES
The drastic reduction of the components offers significant cost advantages. Time for installation and mainte-
nance is reduced significantly. A possible troubleshooting is also simplified, especially since the electronic pro-
vides diagnostic options.
LIMAX33 CP-00 is as well suitable for serial production with new installations as for upgrading existing elevator
systems.
6.1 Functional principle
The tape carries the unique positioning information as a magnetic code. It is installed free hanging in the eleva-
tor shaft by use of a mounting kit. The LIMAX33 CP-00 is mounted to the elevator car. While the actual meas-
urement is contactless the tape must be kept within a maximum distance to the sensor head. Therefore, the tape
is guided along theLIMAX33 CP-00 by use of the polymer tape guide which is an integral component of the
sensor head.
The magnetic measurement principle is extremely robust. Dust, dirt and humidity do not affect the measurement
in any way. Also, smoke and even higher temperatures have no influence on the measuring quality. Further the
tape is robust enough to withstand the harsh conditions in elevator shafts.

7Technical Data
7.1 Identification
7.1.1 Type Label
The type label serves for the identification of the unit. It is located on the housing of the sensor and gives the
exact type designation (= order reference, see 9) with the corresponding part number. Furthermore, the type
label contains a unique, traceable device number, the production date as well as the hardware and software
versions. When corresponding with ELGO always indicate this data.
Figure 1: Example of a type label for identification of the sensor
7.1.2 Info Label and Info Sheet
Each system is designed for a customer specified configuration (14.1). For subsequent transparency of the
respective configuration it is strongly recommended to attach an info sheet Figure 3 with all important settings to
the documentation of the installation. A label with the configuration ID (Figure 2) is attached on the device
housing as well. Additionally, an info sheet with all configuration information should be attached to the elevator
system (e. g. in the shaft).

7.1.3 Configuration of the Device
The customer has the choice. He may either order an already configured device at ELGO (7.1.3.2), or he
orders a blank device and does the configuration on site.
7.1.3.1 Configuration on site
It is possible to order a blank device at ELGO and do the configuration on site.
In this case same label applies as described in Figure 2, but with blank configuration ID. A sticker with the con-
figuration ID has to be attached onto the info label).
The blank device will be configured with the values / features via CAN-Bus. These can be found on the infor-
mation sheet (Figure 3) in the documentation of the installation. For example, the lift control can be used as
input/display unit for the configuration. In addition to the actual configuration information, the CRC from the
info sheet must be sent to the device.
The LIMAX33 CP-00 will accept the configuration only if the CRC fits. This prevents configuration errors due to
incorrect input or incorrect transmission. After the LIMAX33 CP-00 accepted the configuration it is fixed and it
cannot be changed anymore.
If lift control shall be used as input/display- unit the corresponding features must be implemented.

Constraints for Use (Safety requirements for integration)

8Constraints 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
10.4.3, 10.4.4, 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

Constraints for Use (Safety requirements for integration)
- 19 -
l. The speed limited by safety function “inspection overspeed (final tripping)” can be used to ensure
the worst-case speed for the determination of the braking distance for “pre-triggered stopping sys-
tem” (see point n)
m. The inspection speed is normally limited by lift control. LIMAX33 CP-00 supervises this limitation
by safety function “inspection overspeed (pre-tripping)”. The tripping speed should be chosen so
that is
big enough, so that this safety function does not trip by fail if the car travels in an inspection
trip with normal inspection speed.
small enough so that - in case of a too fast inspection trip by failure - this safety function
has the chance to stop the car by machine brake via safety circuit before the car is stopped
by safety gear (tripping of safety gear cause by “inspection overspeed (final tripping)”
n. The offset of limit positions for upper resp. lower “pre-triggered stopping systems” must be chosen
in such a way, that ample survival space for a person on car roof resp. in the shaft pit is ensured
after the sequence car stopped safety gear tripped limit positions for upper resp. lower “pre-
triggered stopping systems” have been over travelled. Braking distance under worst case condi-
tions must be considered when defining the offsets. Braking distance depends on actual speed
(due to worst case assumption, refer to l and e ), reaction time of CP (see point 8. be-
low) and delay and the deceleration of the safety gear.
o. The feature “trip direction” = “only down” may be used if the safety gear is only unidirectional. In
this case all safety function using the eSGC as an actuator will trip only in downwards direction.
Therefore, the combination “trip direction” = “only down” is forbidden in combination with some
of the safety functions (refer also to c and p). Other safety functions can only be used under
constraints if “trip direction” = “only down” (refer to i and q )
p. LIMAX33 CP-00 is able to fulfill EN81-20 §5.2.6.4.3.1 b.), but only if safety function “working
platform” is enabled. The combination “working platform is 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.
q. If “door bridging / UCM” is enabled and “trip direction = only down” is enabled, tripping of
UCM will act the braking element connected to the eSGC actuator (normally the safety gear) only
in downwards direction. If UCM trips in upwards direction only OC opens (additional to SR1 and
SR2). In this case it must be either ensured that it is in compliancy with the EN81-20 that UCM
can be fulfilled with the machine brake in upwards direction or “UCM in upwards direction”must
be secured by other means (outside the scope of LIMAX33 CP-00).
r. If “UCM only OC” is enabled, only OC will open (additional to SR1 and SR2). In this case the
machine brake is the braking element for the safety function “UCM”. Therefore, the machine
brake must be a certified safety brake in order to fulfil EN81-20 §5.6.7.
s. Safety function “over speed teach (pre-tripping)” is intended to be used as a substitute for ETSL
during teach mode. If this safety function is not needed, it may be disabled. If it is needed, the
tripping speed for “over speed teach (pre-tripping)” should not be higher than the buffer speed.
t. Safety function “over speed teach (final-tripping)” is intended to be used for general additional
safety (without a reference to the EN81-20). It may be disabled if not desired.
u. The Parameter “a”, “Vbuf”, “tdel“ and “offset” must be adjusted in such a way, that – in case ETSL
trips - the car hits the buffer surface with a speed not bigger the buffers are designed for.
v. The OC actuator must be enabled in any case
2. To prevent any short-circuit between the 24 VDC UP/DOWN signals of the inspection control or the
24 VDC “EN21-21” signal of the electrical safety device and adjacent circuits, the requirements of EN81-
50§5.15 must be met.
3. The technical data (mechanical, electrical and environmental) concerning the LIMAX33 CP-00 - sensor as
defined in chapter 7.3 are valid for constraints for use.
4. The technical data (mechanical, magnetically and environmental) concerning the magnetic tape as de-
fined in a separate data sheet are valid for constraints for use.
5. The value of fuse protecting the safety circuit must be in compliancy with the electrical data of safety circuit
defined in chapter 7.3
6. The value of fuse protecting the eSGC circuit must be in compliancy with the electrical data of eSGC-
circuit defined in chapter 7.3
7. Operation height: up to 2000 m above sea level

Constraints for Use (Safety requirements for integration)
- 20 -
8. The worst case reaction times of relay contacts OC, SR1 and SR2 when a safety function is triggered is
<55 ms and concerning the eSGC <45 ms.
9. Constraints for Installation of magnetic tape according to its instruction manual must be observed
10. A tape presence detector securing the risk of demolition of the magnetic tape must be integrated into the
safety circuit, see also the installation schemes (Figure 8, Figure 9and Figure 12)
11. The OC-actuator must always be integrated in the safety circuit, see Figure 8 and Figure 9.
12. The eSGC-actuator must be connected to an electromechanical braking element following the idle current
principle.
13. The inspection controls signals must be connected following Figure 8.
14. The earthling lug on the LIMAX33 CP-00 must be connected to protection earth.
15. The inductivities switched by the actuators (examples: contactors at the end of safety circuit switched by
OC, SR1 or SR2; tripping coil of electronic safety gear - switched by eSGC) must be equipped by suitable
interference suppression measures; e.g. recovery diodes for DC-circuits; RC-circuits for AC-circuits.
16. The safety functions over speed final tripping, pre-triggered stopping system and ETSL must fulfill SIL 3
and therefore the PFHD of the whole functional chain must be smaller than 100 FIT. Concerning the PFHD
capability of the LIMAX33 CP-00 (16.1).
17. The braking element connect to the eSGC actuator may be:
a) an electronic triggered safety gear,
b) a conventional safety gear triggered by a conventional speed governor, which in turn is triggered
via the remote triggering of the LIMAX33 CP-00
c) another braking element the safety gear or the machine brake (e.g. a rope gripper)
The braking element following a.) can always be chosen, no matter if safety function “over speed final
tripping” UCM, pre-triggered stopping system or working platform should be fulfilled via the eSGC-
actuator.
The braking element following b.) can be chosen, no matter if safety functions “UCM”, “pre-triggered
stopping system”or “working platform”should be fulfilled via the eSGC-actuator.
Overspeed (final tripping) following EN81-20 §5.6.2.2.1.1a.) is normally fulfilled by the conventional
speed governor in this case.
The braking element following c.) can only be used for the safety function “UCM”. The safety functions
“working platform”or “pre-triggered stopping system”can only be fulfilled by a brake acting on the
rails (due to EN81-20).
18. The CAN bus is not intended to be used for safety relevant purposes.
19. After commission, the floor table must be checked before the lift is allowed to be released for public use.
20. A power cycle or a reset must be d to the LIMAX33 CP-00 at least once per year.
21. The reaction time of the electronic safety gear (resp. other braking element on eSGC) is in the responsibil-
ity of the user. In the technical data 7.3, “Solid state contact (eSGC) reaction time” a time of 45 ms is
defined. This concerns to the time from appearance of a hazardous speed until solid state switch is
opened and therefore voltage on trip is switched off. The reaction time of the electronic safety gear is the
time from opening of the solid state switch until braking force is present. The reaction time of the electron-
ic safety gear consists of an electrical and mechanical portion. Concerning the electrical portion refer also
to topic 23.d.
22. It must be ensured that the eSCG-braking element trips (goes to safe state) if the voltage on its trip coil
amounts to 2 V or below.
23. The trip coil of the eSGC-braking element connected to the eSGC-actuator must fulfill the following con-
ditions (refer also to Figure 5), Remark: if resistance or inductivity of the wire from eSCG-connector to the
trip coil have a relevant magnitude, this must also be taken into account
a. L < 1.5H
b. Current consumption < 1A => R > 24Ohm @24V (the eSGC –actuator is secured inside the
CP with a 1A self-resetting polyfuse)
c. L/R > 1ms (recommended): for L/R << 1ms there is a danger that the braking element would
fall during the test of the eSGC-actuator, refer also to chapter 12.5.
d. L/R < 10 ms (recommended). The L/R influences –beside the mechanical construction –the time
for the braking element to fall. A big L/R causes a slower falling of the current through the coil af-
ter the voltage has been switched off. The current again influences the holding force of the coil,
refer also to topic 21.
