5.5.1 Emergency generators should be capable of
being readily started in their cold condition down to a temperature
of 0°C. If this is impracticable, or if lower temperatures are
likely to be encountered, consideration should be given to the provision
and maintenance of heating arrangements, acceptable to the Administration,
so that ready starting will be assured.
5.5.2 Each emergency generator which is arranged
to be automatically started should be equipped with starting arrangements
acceptable to the Administration with a storage energy capability
of at least three consecutive starts. A second source of energy should
be provided for an additional three starts within 30 min unless hand
(manual) starting can be demonstrated to be effective.
5.5.3 Provision should be made to maintain the
stored energy at all times.
5.5.4 Electrical and hydraulic starting systems
should be maintained from the emergency switchboard.
5.5.5 Compressed air starting systems may be maintained
by the main or auxiliary compressed air receivers, through a suitable
non-return valve or by an emergency air compressor energized by the
emergency switchboard.
5.5.6 All of these starting, charging and energy
storing devices should be located in the emergency generator room;
these devices should not be used for any purpose other than the operation
of the emergency generator set. This does not preclude the supply
to the air receiver of the emergency generator set from the main or
auxiliary compressed air system through a non-return valve fitted
in the emergency generator room.
5.5.7 When automatic starting is not required
by these provisions and where it can be demonstrated as being effective,
hand (manual) starting is permissible, such as manual cranking, inertia
starters, manual hydraulic accumulators, or powder cartridges.
5.5.8 When hand (manual) starting is not practicable,
the provisions in paragraphs 5.5.2 and 5.5.3 to 5.5.6 should be complied
with, except that starting may be manually initiated.
