5) Disconnect the two battery packs from the charger. The Channel 1 and 2 LED extinguish on
removal of the battery packs.
D. Troubleshooting
1) If the front panel power LED fails to illuminate, check that the connected supply is within the
correct range. If it is, check the condition of the fuse located in the mains inlet moulding at the
rear of the charger. Replacement fuses should be 3.15A T Antisurge type.
2) When using the charger to charge the supplied battery packs for the first time (Le. prior to
use), it may be that either of the yellow front panel LED fails to illuminate when the packs are
connected to the charger. NiMH batteries will sometimes discharge to a voltage much lower
than their nominal terminal voltage when they have been stored for an extended period.
Under these conditions, the voltage within the packs is too low to be detected by the sense
circuitry within the charger. The charger thus fails to detect the presence of the battery packs
and will not commence the charging sequence.
To overcome this problem the battery detect circuitry within the charger needs to be
overridden. This is done by switching the rocker switch on the charger rear panel to the ON
position prior to applying power to the charger (a reversal of the normal sequence).
Once the battery packs have been 'fully charged in this manner, they regain their nominal
terminal voltage and can be subsequently charged in the conventional manner.
3) If the charger detects a fault during operation the red front panel Fault LED starts to blink in
sequence with the LED for the working channel. This fault could be associated with either the
battery pack, the connection between the pack and the charger, or a fault within the charger
itself. If checking the interconnection and/or connecting a different pack does not irradicate
the fault, then the fault is likely lie with the charger.
4) In the event of difficulties with either the battery packs or the charger, contact Penny & Giles
at the address given at the front of this manual.
