TCB – Traction Control Board
Date:
04-Jul-2000
Introduction
The TCB was developed to meet the requirements of the flat controller series for OTIS machine room-less elevator control systems.
The TCB is used to control the operation of a single elevator car. It is basically an integration of the LCB_II and other control modules on one PCB. It was developed to meet the requirements of the flat controller series of the Gien99 and Gen2-machine room-less elevator
control system (Otis2000-MRLSS) for new equipment.
It works with MCS (Modular Control System) technology.

The Elevator Control System
The Traction Control Board (TCB) is the central control Unit of the system. It is a Logic
Board where all the elements necessary to control the elevator are integrated:
- Power Supply
- Discrete Inputs and Outputs
- Remote Serial Link (RSL) for Car and Hall Signals
- Serial communication line for DUPLEX or GROUP configuration
- Serial communication line for the Service and Maintenance Tool.
The TCB is mounted in the Controller Cabinet. The Controller in turn is the central location
for all the electronic elements of the system.

Remote Serial Link RSL
The RSL consists of a Master Board (TCB) and up to 60 Remote Stations (RS) which are
mounted in the elevator environment. Both links (Car and Hall Link) are terminated with a
Line Terminator (LT1). Each RS can operate up to 4 discrete Inputs and Outputs. In addition
a Position Indicator can be connected.
The configuration of the RSL will be done via EEPROM – Setup with Service-Tool.

Figure 1: Serial Data Line of RSL
All discrete TCB-Signals operated with RSL are listed in the I/O-List.
The I/O-List contains for each signal the Remote Station Address (Addr.) and
Bits (B1 – B4). In addition an Invert Bit determines if a low-active signal is connected.
The differentiation between Output Signals (E1 – E4) and Input Signals (E5 – E8) is automatically done by Clock Cycle number of the RSL-System and has not to be defined in the
I/O-List.
The configuration of the I/O-List is free programmable and stored in the EEPROM of the
TCB. The Service Tool Function SETUP-RSL can be used to set up the EEPROM (see:
Service Tool Manual).

(*) The input signal voltages are clamped to HL2 and +30VDC against voltage spikes by
diodes. Do not use other supply voltages than +30V from the TCB for the input signals.
Otherwise reverse supply via the inputs in an un-powered condition of the PCB may be the
result. (**) An input filter provides a short inrush current of about 60mA for 50µs. This will
help to ‘clean’ relay contacts.

Different Remote Station Boards
6.5.1
Remote Station 11
6.5.1.1 General
The RS-11 board is a member of the Remote Station family. It provides one discrete input
and one discrete open collector output. An on-board 24VDC regulator is foreseen to supply
an indicator (Lamp or LED). The input and the output are accessible by a small 4-pole AMP
connector. A pre-manufactured cable allows an easy and quick connection to the call buttons. 6 jumpers allow to select the board in an address range from 4 to 63.
6.5.1.2 Functional Description
The board incorporates the hardware to interface to the Remote Serial Link and to one car
hall button with an integrated tell tale lamp. The board provides a regulated voltage of
24VDC which is available at P1.3. Because of the heat dissipation capability of the TO220
regulator the output current is derated to 50 mA at max. average VRS supply voltage and
max. ambient temperature.
The output is an open collector low side switch. The load which must not be purely capacitive can be connected to the 24VDC output or to VRS. In any case, the output transistor is
not able to withstand a short of the load, although the LM7824 regulator provides a short
circuit protection. An inductive load can only be used if a free-wheeling diode is attached.
The discrete input In1 at P1.2 accepts 24 VDC or VRS as logic high input voltage. The 6-bit
jumper permits to program the address of the RS-11 in the range of 4 to 63.

6.5.2.1 General
The RS-14 board provides four discrete inputs and four discrete open collector outputs Onboard 24VDC regulators are foreseen to supply indicators (Lamps or LED´s). The inputs
and the outputs are accessible by a small 4/5-pole AMP connector. Pre-manufactured cables allow an easy and quick connection to call buttons. The RS-14 is available in two versions: B1 and B2. B1 is the basic version, while B2 allows a wire B2 allows a wire lenght up
to 150m for the discrete inputs. It also provides increased current (2 * 125mA instead of 2 *
80mA) for the 24VDC regulated outputs.
6.5.2.2 Functional Description
The board incorporates the hardware to interface to the Remote Serial Link and to up to four
call buttons with integrated tell tale lamps. P5 can connected to a position indicator. The
board provides the regulated 24VDC voltage to supply up to four indicators with 40mA each
(2 * 80mA, 2 * 125mA).
The outputs OUT1 – OUT4 are open collector low side switches. The load, which must not
be purely capacitive, can be connected to the 24VDC output or to VRS. In any case, the
output transistor is not able to withstand a short circuit protection. An inductive load can only
be used if a free-wheeling diode is attached. The discrete inputs In1 – In4 accept 24VDC or
VRS as a logic high input voltage. A 6-bit jumper permits to program the address of the RS14 in the range of 4 to 63.

6.5.3.1 General
The RS-18 board provides eight discrete inputs / outputs and a RSL standard serial position
indicator interface. The board is intended to be operated with existing fixtures in modernized
installations as well as with new equipment control systems. Two Versions, C1 and C2, are
available to allow a space saving and ease board fixing. While both version are electrically
compatible, version C2 will be hold in a Phoenix PCB holder for 35 mm DIN rail mounting
with straight WAGO connectors. The version C1 is equipped with angled WAGO connectors
to fit into the WAGO connector field in NE controllers. The discrete I/O lines may have an
extend up to 300m. Various loads like relais, lamps, solenoids and R/C loads can be
switched by the open drain outputs. The I/Os are protected against field typical impacts as
voltage spikes, overload and shorts.
6.5.3.2 Functional Description
The RS-18 has 8 I/Os, accessible by WAGO connectors. The I/Os are arranged in two
groups with four I/Os (group A and B). Each group is controlled by one ICU chip. Both ICUs
share the address line A1 to A6. The ICU for group A is hard-wired to an even address (n)
while the ICU for group B is always dedicated to the odd address (n+1). This permits to
move a board address wise through the range of 4 to 62 with 2 consecutive addresses. If a
conflict with other Remote Station occurs the L1 data driver for n and n+1 may be disconnected separatly from the RSL by the switches EE (Enable Even) and EO (Enable Odd).
The position indicator interface is always driven by ICU-A. Note that the ICUs will continue
to pass data to the outputs and to the position indicator even if n and/or n+1 are disabled.

The ICU inputs will sense the appropriate output level.
If the input is left open the ICU inputs will always sense a logical ´1´.
If the input is left open the ICU inputs will always sense a logical ´0´.
The ICU input is independent from the output level.
´N+2´ Wiring Principle
Obove figures shows the ´N+2´ Wiring Principle which can be found in old elevator installations. The principle is based on only one wire for lamp driving and the call button. The
maximum number of wires required is N+2. The RS-18 is prepared to be interfaced quickly
to this kind of wiring if only the controller is to be replaced during a modernization. The RS18 incorporates pull-up resistors to maintain the call functions if the lamps (working also as
external pull-up resistors) burn out.

a) Exeeding the max. average supply voltage at max. ambient temperature will drive the voltage regulator into its thermal limitation and the regulation is no longer effective. Long term operation of the
board under the describe max. conditions will exponentially decrease its life time and is therefore
not recommended.
6.5.4.2 Feed Through Capacity
Due to the WAGO connector characteristics (no T-Connection possible) the 4 RSL lines had

The 8 discrete open drain outputs are organized in two groups with each 4 channels. The
RS-18 will accept various types of loads and provides short circuit and overload protection.
Due to this protecrions there are some restrictions on what can be successfully switched by
the RS-18.
6.5.4.5.1 Resistive Loads / Lamps
There are no restrictions using resistive types of loads as LED´s and resistors. Electric
bulbs should have a quick thermal response and their incrush current should not be greater
then appr. 14 times the nominal max. current (Inrush_max = 64 DC).
6.5.4.5.2 Inductive Loads
Although the RS-18 provides an output voltage clamping capacibility, inductive loads like
relais and solenoids must have a free-wheeling diode attached!
6.5.4.5.3 Capacitive Loads
Loads with a dominating capacitive character act like a short circuit.

Principle of Operation
The re-leveling zone is physically marked by a magnet stripe which is attached to each
door. Two magnet sensors 1LV and 2LV sense the magnet. The door zone is true if the two
sensors show a true signal simultaneously. Both signals control the relays LV1, LV2 and
LVC.
Requirements: The circuit must be able to tolerate three consecutive failures before a dangerous situation may occur. A dangerous situation is given if the car enters the next stop
and the door bypass is established outside the re-leveling zone.
•
Without involvement of relay LVC
If 1LV and 2LV are true the relays LV1 and LV2 will be operated and the making contacts
LV1_C and LV2_C will bridge the door safety contacts and will allow to move the car within
the door zone.
If the car would leave the door zone one of the signals 1LV or 2LV would become false, deenergizing the relay LV1or LV2. One of the safety contacts would open to interrupt the door
bypass.
•
Failure scenarios
Without involvement of the relay LVC the circuit will only tolerate one failure ( first failure
welding of one making contact or failure of one sensor)
Å
A second failure ( welding of the second safety contact, failure of one sensor) will lead to
permanent activation of the door bypass and dangerous situations. Both failures can not be
detected.
•
Need for self supervision
The relay LVC has been introduced as an element to cover the three failure level requirement. LVC has an active contact in the door bypass and allows the operation of LV1 and
LV2 only after certain dynamic ‘IF’- conditions.

Manual Operation & Testing
9.1
Test of the Door Bypass Circuit
The correct function of the re-leveling relays must be tested periodically by the code
authorities. For the test procedure please refer to the field instruction manual and the controller drawing GAA21100AA. Three switches ( SW9, SW10 and SW11) are foreseen to
verify the functionality of the safety relays REL5 ((LVC), REL6 (LV2) and REL7 (LV1). The
switches are located in the low voltage power supply section of the PCB. No switches are
present in version BA3.
9.1.1
Safety Notice
The test of the door bypass circuits must be done with power applied in order to be able to
operate the relays. Although SW9 – SW11 are properly located, please be aware that
harmful voltage levels (110VAC) are present on the PCB. Please refer to the section 6.2
which shows board areas of higher potentials.
10
Handling Precautions
ESD sensitive components are present on the board. Handle and install the board in an
ESD protected environment.
11
Probing
For voltage test at the Wago connector contacts do not use normal multimeter probes. This
may weaken the contact and in turn damage the board. Special test adapters from Wago
are available. 231-661 for 5.00mm and 231-552 for 7.50mm.
