SUPPLY FAILURE
If the AC mains power fails during operation, the charger will shut
down safely; no damage will occur to either the charger or the
batteries.
When the mains power is restored the charger will default to the Main
Charge program. Batteries which had been identified as charged or
faulty before the supply failure, and which had not been removed, are
recorded, and the charger will not attempt to charge these batteries
(note: this does not apply to PAG Li-Ion batteries).
4.9
CAMERA POWER SUPPLY MODE (Models 9752 & 9753 only)
The above Quasar models incorporate a Power Supply suitable for
powering a camera. The output is rated at 50W, which is suitable for
powering most professional broadcast cameras, without a light.
To enter Power Supply Mode:
plug the camera lead, terminated with
an XLR-4 (M) connector wired pin 1 negative, pin 4 positive, into the
Power Supply connector on the front of the charger, and turn the
camera ON. Charging of batteries will be automatically suspended, and
the power supply output will operate. The camera can be turned OFF
without exiting Power Supply Mode so long as the Quasar remains
powered.
To exit Power Supply Mode:
turn the camera OFF. Power Supply Mode
will remain engaged until the Function Button is operated for one
second, which will return the Quasar to Charging Mode. The Quasar will
auto-matically revert to Charging Mode if the mains supply is
disconnected.

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 ‘FAIL’ 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 ‘ABST’ 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 produce a 'FAIL'
indication, or which have completed a program. If a battery is discon-
nected, the status will revert to the 'ABST' state. Another battery can
now be connected to the free channel without affecting the other
channel.
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.
SERVICING & REPAIRS
SECTION 5
5.1
WARNING:
To reduce the risk of electric shock, do not attempt any
servicing or repairs unless you are qualified to do so. Refer all
servicing or repairs to qualified servicing personnel. The Quasar
contains advanced electronics that 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 may be that a supply fuse has become
open circuit. Equipment supplied for use in the UK is supplied with a
standard UK mains cordset, complete with a moulded, 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.
