E. Set the Display Selector jumper to one of the 3 available positions on JP800 (see photograph previous
page):
•
VOLTS – Place the short jumper in the “upper” position next to the word “VOLTS”. The 3-digit LED
meter display will show DC Volts only
•
AUTO – Place the short jumper in the center position next to the word “AUTO”. The 3-digit LED meter
display will automatically and continuously alternate between DC Amps and DC Volts. The display
shows DC Amps for approximately 6 seconds and DC Volts for approximately 3 seconds.
•
AMPS – Place the short jumper in the “lower” position next to the word “AMPS”. The 3-digit LED
meter display will show DC Amps only.
WARNING:
USE THE JUMP FEATURE ONLY WITH LIQUID
ELECTROLYTE NICKEL-CADMIUM BATTERIES, OR WITH
RECENTLY FILLED NEW LEAD ACID BATTERIES
SUPPLIED FROM THE MANUFACTURER DRY AND
DISCHARGED. FOR EXCESSIVELY DISCHARGED LEAD
ACID BATTERIES THAT HAVE ALREADY BEEN IN
SERVICE, CONSULT THE BATTERY MANUFACTURER TO
DETERMINE IF AND HOW THEY CAN BE SAFELY
RESTORED TO SERVICE.
WARNING:
NEVER LEAVE A JUMPER IN THE JUMP POSITION
DURING NORMAL OPERATION. THIS DISABLES THE
BATTERY VOLTAGE INTERLOCK, WHICH INCREASES
THE RISK OF ACCIDENTALLY OVERCHARGING 12V
BATTERIES WITH THE 24V SETTINGS.
F.
Replace the cover by sliding it straight onto the charger. Ensure the cover’s locating tabs engage the slots
in the chassis. Secure the cover with its four mounting screws
G. The JUMP position allows initial charging of Nickel Cadmium batteries, or new lead acid batteries
supplied from the manufacturer dry and discharged, from a zero charge state. To use this feature,
temporarily
move JP1C from the BOOST setting to the JUMP position. Operate the charger for a short
time, just long enough to retain more than 1.5V for Pb and 1.0V for NiCd per cell. Then disconnect AC
power, remove the cover, and place JP1C back to desired boost setting. Replace the cover as described
above.
WARNING:
USE ONE JUMPER ONLY ON THE DISPLAY SELECTOR
JP800. USE ONLY THE “SHORT” JUMPER PROVIDED
FOR JP800, TO AVOID INTERFERENCE WHEN
REPLACING THE COVER.
(“TALL” JUMPERS ARE TO BE USED ONLY ON JP1.).
