necessary material.
X-232-DC
Configurable load measuring interface for 24VDC operation
- incl. attaching plug
- incl. 2m access line control, free end
Device is connected to the power line by user. CLMI is supplied with all
necessary material.
The CLMI (Configurable Load-Measuring Interface) connects the load measuring sensor to the control unit. The
CLMI continuously compares the measured load to the programmed limits and if necessary activates the
analogous switching output. The switching outputs are connected to the control unit and they send the signal of
the load to the control unit. The relay contacts are provided for:
- Car Empty
- full load (90% group travelling, reduces intermediate stops)
- overload
These values are easily programmable without any means such as the CLMI can be individually adjusted to the
task.
Attention: Depending on execution, the plugs maybe live. Do never handle the CLMI with metal tools and if
necessary disconnect the device from the mains before you start to work with.
Devices constantly connected to the electric circuit must be connected to a circuit breaker (fuse, etc.). It must be
marked as safeguard.
Check the supply voltage before connecting the device. Make sure, that you operate this device only if
you aren’t electrostatic charged and if the device is correctly grounded.
The supply cable must be separate from the signal cable and must not be installed in the same wire. The signal
cable must be shielded and the cable shield must be connected to the grounding clip.
Important advice:
Before commissioning acquaint yourself with the
programming and functionality of this device and
read this manual carefully.

If more than two sensors are connected to the CLMI, a junction box of the series X-914 will be required.
The CLMI sends a digital 0V/24V breaker signal and a relay contact as output signal.
Drill Layout
Degree of Protection, Mounting
The CLMI has the access openings only at the lower side. During the mounting make sure the device is vertically
installed with the access openings and the cable passage at the lower side.
In this way the degree of protection IP22 can be reliably achieved.
Vertical mounting, in this case well protected
by the journal of the yoke

2. Installation
Some Reflections to the Minimum Load Measurement
Background Information about the Floor Detection
The paragraph “Configurations“has explained that the CLMI is potentially able to perform a minimum load measurement. For this
purpose following provisions has been made:
- The possibility to compensate the error factor of the travelling cable (floor detection). The floor detection should be
activated if the maximum weight of the travelling cable amounts 25% of the minimum load.
Example: A minimum load measurement of 40 kg is required. The height of the elevator shaft amounts 12m and the
weight of the travelling cable is 1,5kg/m. According to this, the travelling cable (6m) itself affects the zero point for 9kg
what corresponds 23%. The floor detection must be activated.
- Prevention of the slow drift of the zero point (e.g. at outdoor elevator shafts and variation of temperature). This function
is always on.
The chosen strategy is important to the achievable accuracy. A schedular rating:

Rank 1 and 2: Achievable accuracy does not depend on the suspension of the car, slide guide, etc..
Universal, very accurate measuring strategy but often an inconvenient execution.
Rank 3: Best choice for yoke measurement. By installing a sensor on each journal, torsion forces and
asymmetric bend phenomenon are effectively compensated.
Rank 4: Easy, robust measuring method, can be used everywhere. Widespread at modernizations.
Friction, hysteresis (etc.) at the slide guidance affect the measurement result.
An optimal choice of the measuring position (point at joke with the biggest elongation) can
reduce the error. If possible use a very elastic yoke.
Rank 5: Another easy and robust method. This solution suits in every case where no suitable yoke is available.
Beside the already mentioned errors of the slide guidance caused by friction, the errors of the unequal load distribution
in the cable additionally affect the measurement.
In this case a measurement with two force sensors significantly improves the accuracy, by simultaneously measuring
all cable loads 100% with two sensors.
The CLMI calculates with the floor information the weight of the travelling cable and automatically subtracts
this weight from the measured value. So the zero point remains constant on each floor.
For this process, the CLMI needs information about the car’s floor position. The CLMI can receive this
information through a parallel 6Bit wide interface. The information can be transmitted in Gray code or in
binary code. The signalling lines must be positive switching but the code can be also processed in inversed
logic. (See “Technical Data”and “Setup Menu”)
Control the function of the floor detection by reading the code in the test menu of the CLMI. (See paragraph
“Advices about Commands”and “FAQ“)
The signal “Synch“shows the validity of the code from Bit0 to Bit5. A logic “1” (active) signifies the validity of
the code, and the CLMI evaluates the floor information and load information.
If the signal “Synch“is a logic “0“, the measurement, the current status of the readout and switching status will
be frozen. There won’t be an evaluation of the load information. The polarity of this logic can be inverted by
changing the parameter “L”, refer to the truth table below.
When the floor detection is online, the signal “Synch“ can even be used by putting the signal “Door Open” on
the signal “Synch”. The load is only measured as long as the door is open. So, unwanted signals will be
disabled during the ride.
Please note that the signals are galvanically separated and a separate reference potential is needed!

which shows the status “Minimum Load” will only be activated if a logical 1 is present at this input.
Electrical installation
Advices:
Before the commissioning, control if the
mains voltages are correctly chosen.
Please note the relevant ground and
isolation instructions.
Switch electric loads over 20mA with the
relay contacts, not with the control outputs.
If the CLMI is operated with mains voltage,
the 24V terminal (X1, Pin 1) as supply
output may be loaded with maximal 70 mA.
The terminal might serve to supply an
external overload indicator with 24V.

Manuel_X_232_EN 7 / 13 27.01.2016
Typical Installation, minimum configuration
Advanced Installation
In the easiest variant, a yoke sensor is connected to the CLMI. The relay contact “overload”is then wired to the appropriate input of the
control unit. After commissioning, the CLMI with the relay contact reports the overload to the control unit.
Beside the basic functions the CLMI X-232 offers some expansions:
- Compensation of the weights of the travelling cables
- Input for external motion detector
- Advanced software functions
In this case the +24V wire (Pin 1 at X1) is the output, i.e. it supplies the external overload indicator.

Preparation
Acquaint yourself with functions in the setup menu and set these functions relative to your installation and desires.
A) Programming of the Options in the Setup Menu
1. Press UP at least 10 seconds until E_x appears.
2. You are in the setup menu, now.
3. Set E, F, C, L, S, P and I to 0 provided these parameters aren’t already set 0.
4. Set A to 10 (on-delay = 1 second)
5. Set H to 12 (switch hysteresis 12kg)
6. Wait 10 seconds, the setup menu will be automatically quitted.
Please note: Point A may be shortened, by executing a general reset. (See paragraph “Advices to Commands”)
B) Parameterization of the Load Measurement
7. Make sure the car is empty.
8. Press RIGHT –P0 appears.
9. By pressing UP/DOWN the readout is changed to the desired value when the car is empty. (*)
10. Press RIGHT –P1 appears.
11. Set P1 to 0 by using UP/DOWN.
12. Press RIGHT –P2 (full load) appears.
13. By pressing UP/DOWN set P2 for the maximal allowed car load.
14. Press RIGHT –P3 (overload) appears.
15. By pressing UP/DOWN set P3 to 110% of the maximal allowed car load (therefore consult the information of the car/elevator
manufacturer and the relevant norms)
16. Load the car with the maximal allowed car load.
17. Execute 3 to 6 rides with the elevator.
18. Press RIGHT until P4 appears (teach-in nominal load).
19. By pressing UP/DOWN set P4 to the maximal allowed car load. If necessary add your body weight.
20. Press 1x RIGHT or wait 10 seconds.
21. The device returns to the display mode and it is ready, now.
C) Control the Commissioning
22. During the following unloading, control if the readout proportionally drops to the load reduction.
23. If the display doesn’t exactly drop to 0 afterwards, you can teach-in the zero point in P0 again.
24. Load the car again with 50%...80% of the nominal load and observe the changes on the display
25. If there are large aberrations, teach-in P4 again. Control the installation of the sensors and the behaviour of the car in its
guidance (friction!).
26. Complete the final tests according to the instructions of the elevator manufacturer.
(*) Variant 1
Usually the readout is set 0(kg) when the car is empty. But if the installer is on the top side of the car and his weight affects the
measurement, he must program his own body weight (not 0kg). After leaving the top side, the readout drops to 0.
(*) Variant 2
The readout is set 0 kg, although the installer is on the top of the car. After the last key pressing (UP or DOWN), the installer MUST
NOT press RIGHT but leave the top side of the car. After 10 seconds the CLMI automatically learns the new measured value and
reprograms the zero point relative to the new value (without persons on the top side of the car).
This is the elegant method to program the readout to 0 kg, although the installer is on the top side of the car during the installation.
Wire the supply, sensors, floor detection, motion detector and alarm output according to electrical installation.
Turn on the supply –the display shows a random number, now.

This signifies the car must be load with the nominal load again.
The blinking of the left zero point warns you that a new teach-in is required.
If the change is manually undone in the setup menu, so another teach-in won’t be required.
But this isn’t possible anymore when you have left the setup menu before without undoing the change.

(Q&A)
Q: Can I use KL1 and KL2 in a different way as proposed?
A: Yes, the thresholds are freely programmable. E.g. I can program half load instead of full load.
Take note: The response delay works with KL2 (overload) ONLY, and KL3 (Car Empty) must be activated in
the setup menu before.
Q: After having changed the configuration in the menu “Configuration”, do I always have to calibrate
before commissioning?
A: No, but it is assumed that if the Empty-Car detection and the floor detection Floor (F) are changed, a
general change of the configuration has been done. So before the commissioning another calibration is
required.
The external motion detector (S) can be turned on and off without requiring a calibration again.
(→s. paragraph “Setup Menu“)
Q: How do I have to set the zero point if I have to be on the car while I operate?
A: Consult the paragraph “Commissioning“, Variant 1 and Variant 2.
Q: How can I undo values (after a faulty operation)?
A: By shortly pressing “UP“ and “DOWN“ at the same time the original value will be restored. This is only
possible as long as you are in the relevant menu. If you have left the menu, changes can’t be undone in this
way.
Q: Why is the decimal point to the left rapidly blinking?
A: This blinking shows you that a value has been modified and the device saves the new value.
Q: Do I always have to load the car with the full payload while I am calibrating the car?
A: No, depending on the sensitivity of the sensor 50..75% of the payload suffices. Please note: The
measurement will probably be very inaccurate if you calibrate a large measuring range with a small
reference weight. We recommend no to go below 70% of the payload.
Q: How can I completely reset the CLMI (General-Reset)?
A: Press the keys “UP”and “DOWN”for 10 seconds. All values including the calibration values are deleted,
now.
Q: How can I expand the measuring range over 999kg?
A: Take a tenth of the absolute values of P1 to P4. I.e. when you have a 1500 kg payload, you set P4 to
150. Proceed with the thresholds analogously.
Q: How do I have to interpret the blinking numerical code which is displayed in the test menu?
A: The two digits to the right and in the middle show the reported number of floor in plaintext. The digit to the
left shows the switching state of “Measuring Stop“ and “Empty Car” in the coded form.
Significations:
2xx Ext. motion detector reports “Empty Car“
1xx “Measuring Stop“not active, i.e. measuring is running
3xx “Empty Car”and measuring is running
xx Number of floor in plaintext
After a minute, the CLMI returns itself to the normal operation mode.
Q: Is the CLMI limited to a certain sensor?
A: No, the CLMI processes a mV/V signal which a strain gauge full bridge generates depending on the force
effect. The CLMI can measure at the yoke, fixed point, rope tension, car ground, car frame or at the motors
bed frame. Ask X-Sensors, there are suitable sensors for any imaginable measuring strategy.
Q: How can I request the software version?
A: Return to the normal mode of the CLMI, it shows the load in kg, now. Press consecutively “DOWN “ and
“LEFT“and keep pressing both keys. The display shows a three-digit number. This number represents the
software version. →consult the paragraph “FAQ“

Troubleshooting
Warnings
Q: I try to set P4 by pressing UP/DOWN but it always appears “Err“.
A: You have tried to calibrate with a too low load or with an unavailable span. Load the car with the payload or control the sensor.
You can increase the sensor signal by loading the cabin with 120% of payload. It is understood that also P4 has to be increased to
120%.
You have tried to teach-in P4 although Bit6 at X4(synchronization) is set to “High“. This means “Measuring Stop“ and no
measurement will be executed.
You tried to calibrate P4 with a negative signal span. Check polarity settings of sensor and/or X-232.
Q: The alarm contacts are switching during the ride.
A: Short fluctuations of the measured values can be disabled by increasing the response delay by a few seconds and by adding some
kilograms to the hysteresis value. (→s. paragraph “Setup Menu“)
Alternative: Connect the output "Measuring Stop" to your control unit. In this way, you can synchronize the CLMI to the elevator. E.g.
You can only accept measurements as long as the door is open.
Q: The minimum contact doesn’t switch reliably
A: If the switching hysteresis (→Setup Menu) is set too large, it may occur that the hysteresis is as large as the set limits for the
minimum load measuring. The CLMI cannot clearly determine the status. Reduce the hysteresis by maximal 50% of the value which
was programmed in “PE“.
Q: The minimum contact doesn’t switch.
A: If the parameter “S“ (external sensor) is set to 1, you must pull down Pin 1 at X5 to 0V, thereby KL3 will be activated. If there is a
cable break or defect motion detector, KL3 won’t be activated.
As a general rule, the contacts do only switch, if ALL parameters have been programmed.
Q: The zero point is fluctuating.
A: Depending on the chosen strategy of load measuring, the measuring is more or less immune to any kind of fault. Load measuring
at the yoke or fixed point requires an almost frictionless guidance of the car to generate a repeatable zero point. If you can realize a
load measuring below the ground, the effect of the friction can be completely eliminated.
At the yoke, you can reduce the hysteresis by mounting a second sensor at another yoke profile.
The correct mounting of the sensor is the general condition (no color at the bearing areas, screws well tied up)
Q: After a certain time my display shows nothing except a blinking decimal point.
A: After 30 minutes idle time the display changes to the standby-mode. If you press any key, the display will show plaintext again.
Q: During the installation, I have sometimes realized aberrations of the zero point which slowly disappear.
A: The CLMI has an approximation process of the zero point. Is the measured load closer to 40kg than to zero and when this
measured load doesn’t change for two hours, so the CLMI will slowly adopt the 40kg as new zero point. This process would last a few
days, so the CLMI evaluates an optimal zero point. Long-term errors due to drift or continually mechanical abrasion can be
compensated.
Q: I have two sensor inputs at the CLMI. How does the CLMI interpret the signal from these two sensors?
A: The signal of these two sensors is averaged. Therefore all errors, working in the opposite direction are compensated.
It is understood, that the setup, configuration and operation may only be done by qualified personnel.

General rules for installation
Maintenance, Repairing
Pay attention all the time and mainly during your installation process to all legal rules and security-hints to prevent any accident. Do
always separate the signal lines from power lines (drives, converters) and do never interrupt the signal lines unless you use
designated junction boxes. (X-914)
Tie cable shield (braid) at both ends to a proper ground. Tie all machine parts to one well defined potential by using massive copper
wires. Prevent at any case that a ground current flows over the cable shield. Prevent different potentials in your machine, they will
create currents which can be hardly controlled.
The devices of the serie X-232 do not contain any serviceable parts. Any repairing is done exclusively by the
manufacturer
