the requirements of the European Directive concerning EMI.
Check the functionality of the existing protection and monitoring sys-
tems.
To prevent damages to the equipment and personal injuries, it is
imperative that the following monitoring and protection systems
have been installed:
Overspeed protection acting independently of the speed governor
Overtemperature protection
HEINZMANN will refuse all liability for damage which results from
missing or insufficiently working overspeed protection
Generator installation will in addition require:
Overcurrent protection
Protection against faulty synchronization due to excessive frequency,
voltage or phase differences
Reverse power protection
Overspeeding can be caused by:
Failure of the voltage supply
Failure of the actuator, the control unit or of any accessory device
Sluggish and blocking linkage

1Safety Instructions and Related Symbols
This publication offers wherever necessary practical safety instructions to indicate inevitable
residual risks when operating the engine. These residual risks imply dangers to
persons
product and engine
environment.
The symbols used in this publication are in the first place intended to direct your attention to
the safety instructions!
This symbol is to indicate that there may exist dangers to the engine, to the
material and to the environment.
This symbol is to indicate that there may exist dangers to persons. (Danger
to life, personal injury)
This symbol is to indicate that there exist particular danger due to electri-
cal high tension. (Mortal danger).
This symbol does not refer to any safety instructions but offers important notes for
better understanding the functions that are being discussed. They should by all
means be observed and practiced. The respective text is printed in italics.
The primary issue of these safety instructions is to prevent personal injuries!
Whenever some safety instruction is preceded by a warning triangle labelled “Danger” this is
to indicate that it is not possible to definitely exclude the presence of danger to persons, en-
gine, material and/or environment.
If, however, some safety instruction is preceded by the warning triangle labelled “Caution”
this will indicate that danger of life or personal injury is not involved.
The symbols used in the text do not supersede the safety instructions. So please do not
skip the respective texts but read them thoroughly!
