1.1 Safety Information

WARNING

 Indicates a potential hazard or unsafe practice that, if not avoided, could

result in death or serious injury.

CAUTION

 Indicates a potential hazard or unsafe practice that, if not avoided, could

result in minor personal injury or product/property damage.

NOTE

 Provides application tips or other useful information to ensure that you

get the most from your product.

1-2 BeneVision TMS60 Service Manual

1.1.1 Warnings

WARNING

 There is high voltage inside the system. Never disassemble the system

before it is disconnected from the AC power source.

 The system must be connected to a properly installed power outlet with

protective earth contacts only. If the installation does not provide for a

protective earth conductor, disconnect it from the power line.

 To completely disconnect the power supply, unplug the power cord.

 To avoid the electric shock, disassemble the central charger after the

central charger is disconnected from the AC power source for five minutes

later.

 Dispose of the package material, observing the applicable waste control

regulations and keeping it out of children’s reach.

1.1.2 Cautions

CAUTION

 Make sure that no electromagnetic radiation interferes with the

performance of the system when preparing to carry out performance tests.

Mobile phone, X-ray equipment or MRI devices are a possible source of

interference as they may emit higher levels of electromagnetic radiation.

 Before connecting the system to the power line, check that the voltage and

frequency ratings of the power line are the same as those indicated on the

system’s label or in this manual.

 Protect the system from damage caused by drop, impact, strong vibration

or other mechanical force during servicing.

1.1.3 Notes

NOTE

 Refer to Operator’s Manual for detailed operation and other information.

2 Principles

2.1 System Operating Principle

TMS60 is a digital telemetry monitoring system consisting of the transmitter (TD60), the

receiver (RC60), the antenna array. The transmitter sends the patient’s physiological

information to the receiver, which then transmits the information to the Central

Monitoring System (CMS) for analysis, displaying, storage and printing. The transmitter is

attached to the patient, whereas the receiver is used together with the CMS. TMS60

telemetry monitoring system is intended to monitor and display a fixed set of parameters

including ECG, Resp, SpO

2

, N IB P, HR and PR under hospital environments. The Resp

module, SpO

2

module, and NIBP module are optional.

The following is a simple illustration:

Figure 2-1 TMS60 Telemetry Monitoring System Diagram

NOTE

 The distance between the TD60 and the antenna should be at least one

meter.

2.2.2 Overview

The transmitter mainly consists of the MCU, ECG circuit, SpO

2

connector, WMTS circuit,

Bluetooth module, Power Circuit, and Display and Control Module.

The ECG circuit provides the amplified ECG signals, which supports 3-lead and 5-lead

modes.

SpO

2

module is externally connected to the transmitter.

WMTS circuit is to send ECG data, SpO

2

data and status information out .The shielding

layer of the ECG lead is the transmitter antenna.

Bluetooth module is used to transfer configuration between the transmitters.

The Display and Control Module consists of a LCD, a touch screen, a LED indicator, a

speaker, and three keys. It is used to display ECG, SpO

2

waveforms and transmitter status,

etc, and allow users to control transmitter.

BeneVision TMS60 Service Manual 2-3

The MCU circuit is the core of the transmitter, enabling the following functions:

 Button signal detection

 SpO

2

connector

 Status detection, such as ECG overload detection, lead off detection, PACE

detection, etc.

 ECG data processing

 MWTS circuit control and Baseband signal generation

 Bluetooth module control

2.2.3 Receiver

2.2.3.1 Principle Diagram

Figure 2-3 Receiver Principle Diagram

The receiver comprises the AC/DC power source, power adapter board, amplifying and

branching module, 4-channel receiver, LED board, main control board and network

interface board.

2-4 BeneVision TMS60 Service Manual

2.2.3.2 AC/DC Source

The AC/DC source is to convert the externally inputted AC source into a 9V DC by means

of isolation. The inputted AC voltage range is from 90V to 264V, and the outputted

voltage/current is 9V/6.5A.

2.2.3.3 Power Adapter Board

The power adapter board is to drop the 9V DC coming from the AC/DC source to a 5V DC

and then output it with the 9V DC.

2.2.3.4 Amplifying and Branching Module

The amplifying and branching module is to amplify, filter and branch RF signals. The

module allows two amplifying, filtering & branching circuits with circuit parameters in full

symmetry. Each circuit amplifies, filters and branches the RF signals received by its

corresponding antenna and then outputs 4 channels of RF signals. Therefore, there are a

total of 8 channels of RF signals, which are then sent to the 4-channel receiver for

processing. The 9V DC linearly drops down to an 8V DC, which then goes to the

amplifying and branching module. The antenna array is shared by all receiving modules.

Therefore, in order to compensate for the branching attenuation of the signal, a LNA (low

noise amplification) is added before the branch divider. Besides, to avoid that the LNA is

blocked by strong out-band signal interference, filtering circuits shall be added in front of

and behind the LNA.

2.2.3.5 4-Channel Receiver

The 4-channel receiver divides the two channels of antenna signals coming from the

amplifying and branching module into four channels of RF signals through the 4-channel

branch divider. The MCU of the 4-channel receiving board will estimate the received

signal strength (RSSI) and then select the corresponding antenna signals through the

antenna switch. The selected signals will be respectively sent to the receiving modules for

filtering, amplifying, mixing, filtering and demodulating. The demodulated 4-channel

analog signals will then be sent to the MCU system for clock and data regenerating. The

regenerated data is packed by CPU and then delivered via the asynchronous serial port to

the main control board for processing. The 9V DC linearly drops down to an 8V DC, which

is then stabilized into a 5V and a 3.5 V supplying power for the 4-channel receiver.

2.2.3.6 Main Control Board

After receiving the data coming from the 4-channel receiving board, the main control

board will pack them and then delivers them to theCMS through the Ethernet. The

speaker of the main control board will give a short beep when the initialization is over,

and will beep continuously when an initialization failure or a hardware fault occurs.

BeneVision TMS60 Service Manual 2-5

2.2.3.7 LED Board

The LED board has two green LEDs, respectively indicating the power status and the

communication status of the receiving module.

2.2.3.8 Network Interface Board

The interface between the main control board and Ethernet consists of the network

isolating transformer and interface connector.

2.2.4 Central Monitoring System (CMS)

BeneVision Central Monitoring System comprises powerful system software and

high-performance computer components. It constructs a monitoring network by

connecting monitors and telemetry transmitters. By collecting, processing, analysing and

outputting the information coming from monitors and telemetry transmitters, the CMS

can achieve centralized monitoring over multiple patients so as to greatly promote the

efficiency and quality of the monitoring work.

The CMS is capable of connecting up to 32 telemetry transmitters.

2.2.5 Central Charger

The central charger inner structure consists of three boards, as shown in Figure 2-4:

2-6 BeneVision TMS60 Service Manual

Figure 2-4 Central Charger Inner Structure

1. AC-DC board (one)

Switching the AC circuit to the DC circuit.

2. Main board (one)

Including the charge circuit, MCU, and LED indicator.

3. Battery interface board (10)

Three kinds of wires connect with those boards:

 AC-DC socket + wire (P/N 0651-20-76879)

The wire connects the AC socket and the AC-DC board.

 Main board wire (P/N 009-003327-00)
