The new PD9200
Series RV Converter/Chargers have our patented Charge Wizard
built-in to provide you with the most advanced RV battery
charging system on the market today. The Charge Wizard is a
micro-processor controller that constantly monitors your RV
battery voltage and then automatically determines which one of
four modes of operation is best suited to recharge or maintain
optimum battery condition. The four modes are BOOST, NORMAL,
STORAGE and DESULFATION. The Converter Status Remote Pendant
will show you which mode the converter is operating in.
The Indicator Light on the Converter Status Remote Pendant will
display the mode of operation as follows:
all of the time – Indicates the unit is in the BOOST MODE
and the converter output voltage is 14.4-volts and is in the
process of recharging the battery up to 90% of full charge
as fast as possible. This mode is usually automatically
selected after dry camping
Rapidly (from once to many times a second) – Indicates the
unit is in the NORMAL MODE and the converter output voltage
is 13.6-volts. In this mode, the converter is safely
completing the charge of the RV battery.
Slowly (every 6-8 seconds) – Indicates the unit is in the
Storage Mode and the converter output voltage has been
lowered to 13.2-volts. In this mode the RV battery is fully
charged and the converter is maintaining the charge, without
causing gassing or water loss.
The Manual Switch...
The Manual Switch allows the operator to check to see if the
Charge Wizard is operating properly as follows:
Press and hold the Manual Switch and shortly the Indicator
Light will remain “ON” all of the time, indicating the unit went
into the BOOST MODE. Continue to hold the switch and shortly the
Indicator Light will start blinking rapidly (every 2-3 seconds).
This indicates the unit went into the NORMAL MODE. Continue to
hold the switch and the unit will go into the STORAGE MODE, and
the Indicator Light will start blinking slowly (every 6-8
seconds). Once the switch button is released, the Charge Wizard
will again read the RV battery voltage, and after some period of
time, automatically select the proper mode of operation.
The Desulfation Mode
The DESULFATION MODE is only active when the Charge Wizard is
in the STORAGE MODE. During this mode a timer in the
micro-processor automatically switches the Charge Wizard to the
BOOST MODE for 15-minutes every 21-hours. This higher voltage
causes some slight gassing, and mixes up the battery electrolyte
to prevent battery stratification, and the resulting sulfation
of the plates, which is the leading cause of loss of battery
Note: When no 120 VAC power is applied to the RV through the
Shore Power Cord, or Generator, the Indicator Light will remain
"ON" at all times. This indicates that the Charge Wizard is
monitoring the battery voltage.
