10.1.4 Safety Test Connector (8D)
An external motor relay (SW) can be connected to this terminal (8D.1 & 8D.2). The feedback contact (NC) of this relay must be wired into the DBD-chain (8D.3 & 8D.4).
This connector is also used for the EN81 Safety Test during code inspection. Therfore the bridge between 8D.3 & 8D.4 needs to be opened.

11.1.2 Purpose
This document will be used to assist in the installation and replacement of the CSB Monitoring System, (RBI), and when CSB replacement is performed.
11.1.3 Overview
The CSB monitoring system’s function is to monitor the condition of the steel cords inside the CSB continuously and to signal the car controller of the CSB status. The CSB status is
communicated as an alert or an alarm along with the monitor system health. The controller could be connected to REM, which can provide the alert, alarm and system health to local personnel.

11.2 Wiring
11.2.1 Wiring Method
The wiring method depends on the existing code and local company practices for your location of installation. The CSB monitor is capable of attaching standard flexible conduit or supporting a jacketed cable. Remove the housing cover and pull wires and connectors through the fitting mounted on the housing. The wire connectors can only go on their mating plugs. The wiring table shows specific applications. Connect the other end of the wiring harness at the controller according to the controller wiring diagram.

11.3 Set-Up 11.3.1 Power-Up
All CSBs, connectors, monitor board and wiring must be installed before you apply power to the unit. Applying power will light the power LED and the belt status LEDs. The power LED should be in a continuous on state and the belt status LEDs should be flashing fifteen, (15), times with a pause between each set of flashes. This is called the standby mode. When the CSB monitor unit is in this mode it is not monitoring the CSBs. A learn operation is required. There are three reasons not to be in standby mode when the power is applied. The first is a problem with the power and/or power wiring to the unit and the second is a bad monitor board. The third will occur upon belt replacement, if an old board is being used with new belts (a new learn is required for the new belts).
Check wiring and turn power on.
Power LED should be on continuously.
1 – 5 CSB status LEDs should flash 15X
regardless of how many
CSBs installed.
11.4 Learn Operation
Learn operation is required for the system to start monitoring the CSBs. This operation provides the starting resistance measurements of the CSB cord pairs to the CSB monitoring system. During the monitoring operation, the newly measured cord pair resistances will be compared to the starting resistances on a regular basis to determine if it has reached its alarm or alert thresholds. The preferred timing of a learn would be towards the end of the elevator system installation, possibly the last step. At this point it is expected to have all the issues related to CSB installation resolved with a settled system. A learn operation is performed by depressing the learn switch five, (5), times within five, (5), seconds. This is done to avoid accidental activation of a learn run. The learn switch is located on the CSB monitor board and is labeled “Learn” and “SW1”. If you did not press the learn switch accurately wait an
additional five, (5), seconds and repeat the process. Pressing the reset switch labeled “Reset”
and “SW2” during the learn process will abort the learn operation. The learn operation takes approximately 90-120 seconds to complete. During the learn operation the belt status LEDs will sequentially flash. This light sequence has no significance to the installation other than an indication that the learn operation is in progress. When the learn operation is successfully complete the system will go directly into monitor mode, continually checking the integrity of the CSBs. The belt status LEDs will flash once, (1), and pause, flash once, (1), and pause and continue this flashing mode until an alert or alarm is triggered. The belt status LEDs for belts not installed will remain off. The table, System Status LED Table, on the next page defines and explains the status LED flashes.

Then resetting..
It is important to measure the CSB length accurately (+ 100mm). Check with your area for a preferred method. A couple of methods are as follows. Using a tape measure and a light colored marker or tape, physically measure the belt by marking the CSB at known lengths and recording those lengths. Then add up all of the recorded lengths. The second approach would be to use a string with a known length and to use the string to mark the CSB. Then record all the marks. This value will be used to perform the learn operation. See the following page for the diagram of a typical system, and the measurements to be taken to arrive at the total belt length.
Note: You must have control of the car at all times while measuring the CSB.
Once the learn operation has completed, the CSB Monitor will reset itself, causing unreadable characters on the service tool screen. The service tool must be reset, or unplugged and re-plugged into the CSB Monitor unit to reset.
At this point, it is important to verify through service tool if the current value of cord
resistances are greater than the starting resistances (typically within 1% or so,
however, can vary based on the usage of the elevator). If is very important to check
and correct the belt length entry if the Starting resistances are higher than the
current resistances. See Appendix A for procedure to record starting and current
resistances.
11.6 Belt Measurement
Prior to setting up the CSB Monitor unit, the belt length must be measured. It is important to measure the CSB length accurately (+ 100mm). Check with your area for a preferred method. A couple of methods are as follows. Using a tape measure and a light colored marker or tape, physically measure the belt by marking the CSB at known lengths and recording those lengths. Then add up all of the recorded lengths. The second approach would be to use a string with a known length and to use the string to mark the CSB. Then record all the marks. This value will be used to perform the learn operation. Note: You must have control of the car at all times while measuring the CSB.
For sheaves of all equal diameter:
• Calculate: (A + B + C + D + E + (1.5*Sheave diameter*3.14) + (2*belt length in termination) +(belt length beyond termination to CSB connector at each end))
• Divide result by 100 to get total belt length in meters for entry into service tool for manual learn For drive sheave of different diameter than idler sheaves:
• Calculate: A + B + C + D + E + (0.5*Drive Sheave diameter*3.14) + (3.14*Idler sheave diameter) + (2*belt length in termination) + (belt length beyond termination to CSB connector at each end)
• Divide result by 100 to get total belt length in meters for entry into service tool for manual learn
Notes:
(1) All lengths measured in cm (2) Sheave diameter:
32kN system = 10.0 cm (typical)
64kN system = 11.5 cm (please verify, in NSAA the drive sheave is 11.5cm and all idlers are 15cm) (3) Belt length in termination
32kN termination = 2.61 cm 64kN termination = 2.75 cm

11.7 Fault Clearing
Press SW1/Learn switch three, (3), times with-in five, (5), seconds.
The purpose of this function is to allow mechanics to clear faults that are latched in the system.
The detection of faults like an alert or an alarm latch in the system and cannot be cleared by simply cycling power. However these faults could have been triggered due to an improper installation or a defective CSB connector or a condition other than the CSBs themselves. In these types of situations the procedure allows you to get the system back in operation when the root cause is corrected. Fault clearing will take up to twenty, (20), seconds to activate.
11.8 Reset Operation
Press SW2/Reset switch during a learn operation.
This function allows the mechanics to abort a learn operation while it is in progress. This is required if a learn operation was inadvertently activated.

11.9 RSL Addressing
Some elevator systems use RSL. The address of the CSB monitor board will be listed in the specific wiring diagrams for the elevator system being installed. Verify that S1 is set to the address listed on the wiring diagram. If the elevator system does not use a RSL, S1 should be set to address 0, (zero).

11.10 ESD Protection
Note: When installing or working on the CSB monitor use ESD protection.
You must always use a part with the exact same part number when replacing a LRU in the monitor system.
Failure to do so will result in a non-functioning unit.
