the supply failure, and which had not been removed, are recorder, and the
charger will not attempt to charge these batteries (note: this does not apply
to PAG Li-Ion batteries). The charger will then fully charge the remaining
batteries.
4.12 GENERAL
The charger continuously monitors the status of all channels and provides this
information to the screen.
If the charger detects a severely faulty battery while a program is running, a
'faulty' indication will be displayed. This could be caused by one of several
conditions, such as a very old or damaged battery, a short circuit battery, or
an excessively high or low voltage battery. An 'absent' indication will be
displayed if a battery becomes open circuit while being charged. Conditions
that could cause this include a blown battery fuse, a battery's internal
thermal cutout operating, intermittent connections, or a disconnected
battery.
The charger will not attempt to process batteries which are indicated as
'faulty', or which have completed a program. If a battery is disconnected, the
status will revert to the 'absent' state. Another battery can now be connected
to the free channel without affecting any of the other channels.
To the charger there is no difference between a disconnected battery and one
that is open circuit. If the charger indicates that a battery is disconnected
even though it appears to be plugged in, check the battery fuse and any
leads and adaptors before suspecting the charger of a fault.
Each battery will be charged to its maximum available capacity, and no
advantage is to be gained from attempting to charge it further. Although
re-application is safe, repeated attempts to overcharge a battery may
overheat the battery, resulting in a shortened life.

SECTION 5
5.1
PAG Pulsar chargers are based upon advanced electronics and do not require
periodic maintenance. Consequently there are no user-serviceable parts inside.
5.2
Qualified electronics engineers who wish to gain access to internal assemblies
should note that parts of the power circuit retain a high voltage even after the
mains supply has been disconnected. Wait for a period of five minutes
following disconnection before commencing disassembly.
5.3
When the charger is correctly connected to a mains supply and the display is
not functioning, it is possible that a fault has developed.
Note that U.K mains plugs are fitted with a fused plug. If this fuse has
become open circuit it should be replaced by another of the correct rating
(see 'Specification' section 2.14). USE ONLY A FUSE OF THE CORRECT RATING.
If the replacement of the fuse fails to correct the above symptoms, do not
attempt further fuse replacement.

3131.
5.4
PAG Pulsar chargers feature a fail-safe shutdown mode. In the unlikely event
of an internal malfunction, an error message will be displayed on the screen to
show that the charger is in shutdown mode. This could be the result of any
number of undesirable situations from which the system is protecting itself,
such as the obstruction off ventilation slots causing inadequate cooling, or the
microcomputer's detection of an internal fault. In these cases the charger
should be disconnected from the supply, any obstruction of the air vent system
removed, and the unit allowed to cool before reconnecting to the supply.
Should the charger re-enter the fail-safe shutdown mode, more detailed
investigation is required. Make a note of the error message, and seek advice
from your nearest PAG dealer, from PAG USA by telephoning 818 760 8265 or
direct from PAG Ltd., London, by telephoning +44 (0)20 8543 3131.
5.5
Unqualified personnel should not attempt further investigation (see paragraph
5.1). Any such interference would invalidate the guarantee and invariably cause
more damage than the original fault.
