1. PREFACE

1.1 GENERAL

The PEM4 Propulsion Efficiency Monitoring system is a microprocessor based instrument for use with

the T-Sense®Optical Torque Measuring System and TT-Sense®Optical Thrust and Torque Measuring

System. The T-Sense®is providing torque, shaft speed and power as input for the PEM4 system. The

TT-Sense®additionally provides thrust measurements as input.

The PEM4 system is supplied with a robust SPU3 Signal Processing Unit, which can be connected to a

large number of extra inputs like flowmeters, GPS, speed log, or one additional T-Sense® or TT-Sense®

in case of twin screw vessels.

This completely unique and compact total solution can be used for simple to very complicated

configurations.

To ensure safe and correct installation and operation, read this manual completely before

installing the equipment and starting operations.

The (micro) SD card should not be exposed to computer viruses, since this could

contaminate the (micro) SD card. Contamination could disturb good working of the system.

1.2 SYMBOLS

The following symbols are used to call attention to specific types of information.

A warning to use caution! In some instances, personal injury or damage to the instrument

or control system may result if these instructions are not followed properly.

While every precaution has been taken in the preparation of this manual, no responsibility for errors or

omissions is assumed. Neither is any liability assumed for damages resulting from the use of the

information contained herein. Specifications can be changed without notice.

2. SYSTEM DESCRIPTION

2.1 PEM4 Propulsion Efficiency Monitoring System

The PEM4 system is a modular propulsion efficiency system. This manual describes the combination of

the PEM4 with the SPU3 (Signal Processing Unit). The PEM4 stand alone system is able to calculate

torque, speed and poweroutput data. The PEM4 stand alone is describedin a separate technicalmanual,

(TIB-669 T-Sense®and PEM4 stand alone). The PEM4 system in combination with the SPU3 can

manage a maximum of 12 Flowmeter inputs in with PT100 temperature inputs related to a maximum of

8 consumers. Furthermore a maximum of 6 ViscoSense®3D inputs, a speed log pulse, GPS NMEA

signal, draft meter and inclino meter can be added as input to the system.

The SPU3 converts all these input signals to one RJ45 Ethernet signal for monitoring purposes through

a PEM4 touch screen or using the IVY®Propulsion Performance Management system.

A RS485 Modbus signal is available for connectionan external system like Alarm and Monitoring System

(AMS) or to connect a separate PC running the optional SPU3 datalogger software.

Functions, which can be performed with the PEM4 + SPU3 system are:

•Measurement and display of the torque, thrust, shaft speed and power.

•Calculation of the average shaft power, shaft speed and torque during the last 1, 4 and 24 hours.

•Calculation of the total energy, total revolutions and total CO2emissions including reset.

•Calculation of the fuel consumption in kg per nautical mile, fuel consumption in kg per hour, fuel

consumption in gram per kWh (Specific Fuel Oil Consumption - SFOC), average fuel consumption per

nautical mile, fuel temperature compensation and calculation of the total mass per fuel type per

consumer including reset.

•Calculation of thrust, thrust power quotient, when a TT-Sense®sensor is installed.

•Displaying of parameters, engine load diagram and power/speed diagram.

•Above mentioned calculations for twin screw vessels when an additional T-Sense®or TT-Sense®

system is installed.

The SPU3 can be installed in the vicinity of the flow meter(s) and/or booster unit or in the engine control

room (ECR). The PEM4 touch screen can be installed in a control cabinet or control panel in the ECR

and/or on the bridge.

2.2 SYSTEM SECURITY

Besides checking the status of the torque measurement system and/or flowmeters the PEM4 + SPU3

system also checks itself continuously for program and configuration data integrity, normal program flow

and power supply conditions. All alarm messages will be logged in a dedicated alarm screen.

4. SAFETY INSTRUCTIONS

There are no special safety instructions for the equipment.

5. UNPACKING

Let the equipment acclimatize inside the closed box for at least one hour at the location where the system

will be installed.

When the equipment is taken out of the box, please leave the special protection supplied with the

equipment as long as possible in place to avoid any damage.

The special protection should be stored for the unlikely event the equipment has to be sent for repair.

Dispose of the packing material should be done according to the laws of the country where the equipment

is installed, or according to the rules that are applicable on the vessel.

•Be careful when unpacking the electronic equipment. The content is fragile.

•Do not press on the PEM4 touch screen.

•Be careful not to damage any of the connectors, control modules or wiring.

6. INSTALLATION AND FIRST USE

The PEM4 + SPU3 system will be delivered with the software and correct data settings installed. First

connect all the inputs and outputs to the components. Connect for the PEM4.10 version a grounding

cable to the grounding screw on the backside of the screen, see section 17 drawing 0815-1126.

The power supply wires should be connected at last.

Note: There is an ON/OFF switch on PEM4 touch screen. When the power switch is switched ON the

screen will turn on.

Check if the inputs are connected correctly through menu <ALARMS> <Signals(raw)>.

In case of any errors the connection(s) or connected equipment(s) should be checked and corrected.
