INTRODUCTION

1.5 IDENTIFICATION

1.5.1 General

Before using this generating set it is very important to identify the set correctly. To communicate for service or ordering parts it is also essential to correctly identify the generating set. Also for the daily operation of the generating set it is necessary that the operator knows the correct specifications.

All required identification data are on the identification plate. For location of the identification plate see figure 1.

Fig. 1: Location identification plate.

1 The identity of the generating set is given by the

SERIAL NUMBER.

When this number is available the manufacturer can trace the specifications of the generating set. On the identification plate are also some basic features of the set:

2 POWER

The identification plate gives the nominal maximum continues load in kVA (= kW) calculated with power factor one. When calculating a load one should always take into account the power factor or cos phi of this load. The power should never exceed the nominal power as shown on the identification plate.

Power is rated at an ambient temperature of 40°C and a seawater temperature of 25ºC. For higher temperatures the generating set has to be derated.

3 VOLTAGE shows the nominal voltage.

This voltage should be within the specified tolerance at the nominal frequency.

4 FREQUENCY is shown in Hz and is determined by the speed of the engine (RPM). 50 Hz correlates with

1500 rpm.

5 CURRENT shows the maximum current that is acceptable at the specified frequency, voltage and power factor.

6 WEIGHT shows the net dry weight (approximately) in kg. This is without fuel, oil, packing and external installation equipment

7 CE-marking: the “CE” symbol shows that the generating set is build according to European

Community safety regulations. This includes the regulations regarding the safety of pleasure craft, safety of machinery, electric safety and electric magnetic compatibility (EMC) and other relevant directives.

Safety also relies on the installation, application and circumstances. See also the remarks in this manual under

SAFETY

Before changing a factory setting you are advised to consult the manufacturer. When the generating set you have to identify is not new you have to take into account the possibility that former users may have changed the settings. Check the settings (voltage, frequency, rpm) when there is any doubt.
