lized electrolyte of a wet lead acid battery. This evaporation can be accelerated by the
applied voltage. Consequently, the ideal float voltage is slightly higher for a gel-cell than
a lead-acid or AGM battery.
The ideal charge/float regimen has been programmed into the Phase Three Charger for
either sealed gel-cell or flooded lead-acid/AGM batteries. Simply make the proper selection
for your battery type via the slide switch on the right side of the charger. The switch posi-
tions are indicated on the front panel. Use a ball point pen or similar object to slide it into
the correct position.
Note:
A wide variety of batteries are now available which do not conform to conventional
descriptions as “gel-cell” or “lead-acid”. You are advised to consult the manufacturer of your
particular battery as to proper charging regimen, and use the battery type selection switch
setting which most closely conforms to the recommended voltages.
See the
SPECIFICATIONS
section for the actual preset charge and float voltages for the
PT-70a and PT-24-40.
D)
Remote Monitor Panel Option
A Remote Monitor Panel is available from NEWMAR (model RP) which will enable you to
monitor the charger’s status at-a-glance from a remote location. Red and green L.E.D.’s
indicate whether the charger is in the bulk, absorption or float phase of the charge cycle. In
addition, the panel features a re-initialize button, which, when pressed, will cause the
charger to restart the three phase cycle. This resets the time-out circuit (see section B,
above) Time-out Circuit, above).
Note:
The charger may not stay in the bulk or absorption
mode after pressing the re-initialize button. If batteries are at or near full charge, the charger
will quickly revert to the float mode.
The panel comes pre-wired with 30' of cable and 4 mounting screws. Simply install the panel
at the desired location and insert the plug on the end of the cable into the remote panel jack
which is located on the right side of the charger. (See FIGURE 10.) The remote panel jack is
identified on the front panel.
Note:
Inadvertantly putting the remote panel plug into the temp
compensation jack (or vice versa) will not harm the charger. If the panel does not appear to
function correctly, check to see that it is plugged into the correct jack.
If additional cable length is required, additional cable is commonly available from most
electronics supply retailers such as Radio Shack/Tandy. Request a 6 conductor modular-to-
modular line cord (part number 279-422, 25 feet long) and 6 pin modular in-line non-revers-
ing coupler (279-423).
E) Temperature Compensation Option
Because low battery temperature increases resistance to charging and high battery tempera-
ture reduces impedence, requiring a lower charge voltage, the ideal charging voltage will vary
depending on the temperature of the battery’s environment when it is being charged.
