Reading The Digital Ammenter (Manual Mode Charging) - Pro-Logix SOLAR PL3730 Mode D'emploi

BOOSTING 12 Volt 118s
Voltage:
Press START again to
deactivate Boost
When complete, press START again to deactivate Boost Mode. Boost Mode has a time limit to prevent overheating
in the charger. If the limit is exceeded, the unit will be in Cool Down mode until it is safe to return to Boost Mode.
When the charger is in Cool Down mode, the display will flash the below message:
Boost Cool Down Mode
Voltage: OFF
Waiting: XXX seconds
(Safe to disconnect)
Note: If the engine spins but fails to start after several starting attempts, there is an engine problem not related to the
starting system. Discontinue cranking the engine until the other problem is found and corrected.
Boost Mode also has built-in safety logic that deactivates this mode if the charger senses that the voltage of the
vehicle battery and the chosen charger operating voltage do not match. An example is shown below:

Reading the Digital Ammeter (Manual Mode Charging)
The ammeter indicates the charging current being drawn from the charger by the battery. As the battery becomes
more fully charged, the charge rate lessens and the ammeter value decreases.
There is no clear-cut way to read an ammeter and determine exactly when charging is complete. At full charge,
the ammeter will still register some current draw (approximately 50% of the charger's output rating). In many
cases, overcharging can occur if the charger is not disconnected when the battery reaches full charge – or sooner.
Therefore, it is very important that you follow the Charging Time Instructions provided in this manual.
Several battery conditions can also cause the ammeter to appear to indicate a battery near full charge, when in
fact, charging has only begun:
Cold Batteries (temperatures lower than 32ºF or 0ºC) will begin charging at a low rate of charge. But as
the battery warms up through charging, the charge rate will increase. Then, as the battery charges up, the
charge rate will decrease normally.
WARNING: Battery explosion can injure, and cause property damage! To reduce the risk of battery
explosion, check to make sure a cold battery is not frozen. Battery explosion can result from
attempting to charge a frozen battery.
Sulfated or Deeply-Discharged Lead-Calcium Batteries require a special activation procedure. See
Pre-Charge Battery Activation.
Shorted Batteries when the battery being charged has a short circuit, the ammeter will display high
current values. If, after 5 to 10 minutes of charging, current has not started to decrease, unplug the charger
and discontinue charging.
Observe the digital voltage reading on the display (while not charging) to read the battery voltage. If the voltage is
less than 12.0 Volts for a 12 Volt battery or less than 6.0 Volts for a 6 Volt battery, plug the charger back in and
resume charging. If, after another 15 to 20 minutes, the ammeter has failed to move lower, repeat the voltmeter
test. If the voltage has not increased, the battery needs to be serviced or replaced.
CAUTION: Do not use ammeter to determine when full charge is reached. Failure to comply with this caution could
cause the battery to be damaged from overcharging. The battery could overheat and even explode.
CAUTION: Remember to follow the duty cycle! If the vehicle
12.0V
doesn't start after 5 seconds, stop and wait for 4 minutes.
The charger is equipped with a safety mechanism that limits
crank duration to protect internal components.
