When all connections are secure,
the power switch on the PLP-CCC3
AC power supply unit can be
turned on. Two LEDs on the PLP-
CCC3 provide operating condition
indication:
1.
When the PLP-CCC3 is
operating correctly and the
internal batteries of the PL-P are
being properly managed, the
I- LED will light. The intensity of
this LED indicates the rate of
charging supplied to the PL-P.
With the PL-P switched off, the
LED will be at maximum
intensity as the power cells are
being charged at the rate of 400
mA. This rate of charge will fully
replenish completely flat power
cells in 12 hours. When the PL-P
is turned on, then the I-LED will
get dimmer. This serves as a
quick check that everything is
working normally.
An electronic counter inside the
PL-P signals the PLP-CCC3 to
enter this 12-hour, full-rate
charging cycle every time the
PL-P has been turned on and
then off. This technique can be
used to bring a new set of re-
chargeable batteries to full
charge.
2. If the rechargeable power cells
in the PL-P have not been
correctly installed or are not
being correctly managed, when
the PLP-CCC3 is switched on,
the U-LED will light. This
indicates that a faulty condition
exists with the following
possibilities:
• The male Lemo connector of the
PLP-CCC3
is not properly connected and/or
seated in the Power Pack socket
of the PL-P.
• The rechargeable power cells in
the PL-P are faulty and will not
accept a charge.
• One of the internal fuses on the
DC-to-DC converter circuit of the
PL-P has blown. (Please refer to
an authorized Nagra agency for
the repair.)
3. If neither LEDs on the PLP-
CCC3 are lit, the following
conditions may exist:
• The power cord of the PLP-
CCC3 is not connected properly
to the AC power outlet.
• The internal fuse of the PLP-
CCC3 AC power supply unit is
faulty or blown.
To restore proper operating
conditions, examine each point
above and correct if necessary. If
the condition persists, please return
the PL-P and the PLP-CCC3 to an
authorized Nagra service agency.
