Introduction
 Introduction
What is the Otis Pulse tool:
➢ It’s a tool that controls permanently the state of
the coated steel belts.
➢ It’s a new technology based on checking the pair
of resistances inside of the coated steel belt.
➢ That’s why Otis call the tool RBI, this means
Resistance based inspection.

Why Otis used this tool?

➢ If Tool not installed, 5 years after installation,
belts must be replaced or inspected annually
with appropriate tool (very high cost).
➢ Some countries (locations) require annual
inspection after installation.
➢ If the Tool is installed we don’t need to replace
the belts every 5years, and this tool check
permanently the belts, the technician don’t need
to used another expensive tool to check annually
the belts.
➢ The tool can be used all Gen2 with coated steel
belts.
Belts details

• Grooved CSB
(32/64KN)
– Has either straight
or “V” shaped
grooves on side
exposed to drive
sheaves.
– Contains 12/24 steel
cords, 1.65mm dia.,
30/60mm wide and
3mm thick
 CSB Retirement Criteria

Resistance Based Inspection CSB Retirement Criteria are based on:

– Experimentally observed degradation rate under steady fatigue conditions

– Empirical, quantified relationship between strength and resistance
– Simulation of wear process to compute wear maps showing distribution of
wear along belt in elevator application
– Number of cord pairs monitored
• 1 or 2 missing cord pairs acceptable for 32 or 64KN belts respectively

Models account for uncertainties in:

– Degradation rate
– Usage
– Wear-Resistance
– Temperature
– Electronics
 CSB retirement criteria - Summary

• Alert – Require scheduled belt replacement (within 1 year)

– Resistance thresholds - per table on previous slide
– A 10% decrease in resistance for 24 hours (jacket degradation)

• Alarm – Go to the next landing and shut down, replace belt

immediately
– Resistance thresholds - per table on previous slide
– 50% increase in resistance for more than one pair over single
measurement cycle
– Alert condition for two belts (not applicable for NAA)
– A 10% decrease in resistance for 24 hours in a belt already on alert
status (jacket degradation could mask cord degradation)
– Temperature above 55°C (except NSAA)
– CSB monitor failure
Setup without Otis Tool
 Setup without the Otis Tool
• Setup
– RSL address - field settable with DIP switch
– No set Up required for discrete or relay interface
• User interface
– Push button switch to initiate resistance learn cycle and fault reset
• To avoid accidental learn, switch must be pressed 5 times within 5 seconds
• To reset faults, the switch must be pressed 3 times in 5 seconds
– One status LED per belt
• Slow steady flashing - Normal operation
• Pulsed code – flashes separated by pause representing fault code
• Fault code label provided on the unit
– Push button switch for field testing
• Induces fault that is displayed through LEDs
• Fault must be reset once testing complete
– Serial Port for Retrofit installation use
– Power supply status LED
 Setup without the Otis Tool
Do not set-up the PULSE if the belts are more than 6 months old.

1. Go to the car roof and put the elevator into INSPECTION mode.

2. Move the car upwards to reach the PULSE unit.

Wear the harness

3. Remove the protection cover.

Ex: LED no. 2, 3, 4 are constantly blinking because there are 3 belts.

PULSE fault codes

Blinking with blanks: FAULT
(check the number of blinks to
know the meaning of the fault)

Ex: 5 blinks / Warning, plan on

changing the belts (belts need to
be replaced in the same year.
Power LED must always be lit.
 Setup without the Otis Tool
4. Put the dip switch S1 on 0FF.

Reset

Setup without Otis Tool

5. Push the LEARN button (5 times in 5 seconds).

6. The set-up starts. Led's are blinking.

7. The set-up will last for about 2 minutes.

8. The set-up is good, once the Led of each connected belt is blinking regularly.

 Setup without the Otis Tool

If the PULSE is not installed, you should check visually the

status of the belts and the belts must be replaced every
5years.
Setup with Otis Tool
 Setup with Otis Tool

We can used the Otis tool to do automatic learning (only used when the
belts are new), or to do again a manual leaning (used for existing belts
having more than 1 year)

Attention:
Before lunching the setup with the tool check the state of them (see
procedure in the next slides).
 Setup with Otis Tool
This procedure can only be used for belts used for more than 1 year
and new learning is needed.

1- Step:
Estimation
of the Belt 1.Check and save the « Start resistors » on each pair for all belts
length using the Otis tool.
2.By pushing in the tool: F-2-2, choose one by one the belts and
save all values.
3.Calculating the medium value read. Example: maximum read 22
ohms and minimum 18 ohms the medium value is 22+18/2=20
ohms
4.Divide the medium value by 0,35 and you obtain the
corresponding length value of the belts. (the resistor for the belts is
0,175 ohms/m at 25 c°)
For our example : for this medium value 20 ohms, we will obtain a
length of belt of 57,14 m.
5.Now we can start the manual setup see the procedure next slide.

The Tool shows :

"B" : The “B” field is for the purpose of entering the belts to be monitored and is
organized as belt 1 up to belt 5 from left to right. Enter a “1” into the belt
positions where belts have been connected to the CSB monitoring system.
For example, if you have connected belts 1, 3 and 5, the “B” field should contain
“B:10101”. Or if you have connected belts 1, 2 and 3, the “B” field should contain
“B:11100”.

“L” :Once the “B” field has been filled in properly, fill in the “L” or “Belt Length”
field in meters (note that the decimal point is skipped over during data entry.
For example, if the value was 57,14m “L : 057.14”.
 Setup with Otis Tool
Manual Setup Once both fields are properly filled in, press “Enter” (Shift-Clr) to complete the
data entry. If you have entered an acceptable value for the belt length, the
service tool screen will change to the following:

Once all Starting Resistances for all belts and all cordpairs have been
determined, the service tool screen will change to the following:

Once the starting resistance data has been stored to non-volatile memory and
the CSB monitoring system then resets itself, the CSB monitoring system
indicators should provide indications that the belts you specified to be monitored,
are actually being monitored. If you receive any other indication, you must not
assume you have a successful installation.

If you have not entered an acceptable value for the belt length, the service tool
screen will change to the following:
 Setup with Otis Tool
Manual Setup

The CSB monitoring system software will calculate the starting resistance for all
CSBs specified in the B field using the formula:
StartingResistance = BeltLengthInMeters * 2 * NewCordResistancePerMeter

The factor of 2 is because CSB cords are paired so the actual resistance
measured by the monitoring system is that of 2 cords.

Acceptable starting resistances will not exceed 65% of a full scale reading in the
CSB monitoring system’s measurement subsystem.
The full scale reading for grooveless 32KN CSBs is 118 Ohms and
grooveless 64KN CSBs is 182.0 Ohms.

In addition, no starting resistance under 1 Ohm is allowed for either grooved or

grooveless CSBs.

Coated Steel Belt Cleaning

Coated Steel Belt Cleaning

In general the CSBs do not require periodic cleaning.
Only if a significant amount of construction debris or a fluid contaminant
appears on the belts will cleaning be required.

The following considerations MUST be adhered to

- If the belt is not dirty leave it alone, do not clean the belt or wipe it down
- If it is a dry contaminant (dust) wipe the belt with a clean dry cloth.
- If the belts need to be cleaned, clean with cleaner # 2 only.

Never use another cleaner on the belts, other than cleaner
