AMETEK/PRESTOLITE POWER ULTRA CHARGE, Owner'S Manual, Page: 22 / 70

Time-of-Day Blockout — The UC2000 Control can be
programmed to disable the charger during a specific
time of day. The charger will turn off at the beginning of
the blockout period, and resume the charge cycle at the
end of the blockout period. Any period of time of day, in
one minute increments, can be used for the time-of-day
blockout period. When a UC2000 is programmed for
time-of-day blockout, and a battery is being charged
when the blockout period occurs, the programmed end
of blockout time will be displayed. This feature can be
used to save on energy costs, provide a battery cool
down period, or to prevent opportunity charging.
Manual Override of Programmed Start Modes —
A UC2000 Control, when programmed for time-of-day
start, delayed start, or time-of-day blockout, can be
manually overridden by pressing the “Enter” pushbutton
while the start of the charge cycle is being automati-
cally delayed by the control. This manual override
feature can be disabled through the “Start Override”
programming function. The manual override feature
allows the operator to start a charge cycle immediately
if a battery is needed sooner than the programmed
start time would allow.
Automatic Equalize — The UC2000 Control can be
programmed for 3 different types of automatic
equalize. UC2000 Controls are shipped from the
factory programmed to automatically provide an equal-
ize charge to every fifth complete charger cycle. The
number of cycles between equalize requests can be
varied from 0 to 30. If the UC2000 is programmed to
automatically provide an equalize cycle every zero
cycles, then an equalize charge cannot be requested
manually and will never be provided automatically. The
second type of automatic equalize mode is when an
equalize charge is desired on a particular day of the
week. When programmed for automatic equalize by
day of week, the UC2000 will provide an equalize
charge to any battery which is connected to the charger
on the programmed equalize day. Additionally, any
battery which is connected the charger previous to the
day of week equalize day will be given an equalize
charge provided that it is at a charge complete status
when the UC2000’s clock calendar switches to the
equalize day. The automatic equalize features allow
for the consistent application of equalize charges with-
out constant attention by the operators. The third
type of equalize is by BID count. When programmed
for this mode, the current complete cycle count is read
from the BID at connect and compared to that of the
equalize cycle counter. An equalize will be requested
when the BID count equals the equalize cycle count
programmed into function 22.
For further information on programming and reviewing
the UC2000 features, refer to the Programming Your
UC2000 chapter and the Reviewing UC2000 Charge
Data section of this chapter.
Programmable Cool Down Time — A
programmable cool down feature allows the battery to
cool down for 0 to 8 hours before the charger
signals charge complete. During the cool down
period the alphanumeric display reads “Cool Down”.
This feature allows the battery to cool down before
being returned to use and can be used to minimize the
battery maximum temperature during operation.
Maximum Battery Temperature — The UC2000
Control can be programmed to interrupt the charge
cycle if the battery temperature exceeds the limit
programmed into function. The temperature may be
programmed from 80°F to 150°F. Once the battery
cools down past the trip temperature the charge cycle
will be resumed. The display will show “Battery Cool-
ing” if the charge has been interrupted and the cooling
period is taking place. A BID must be in use to utilize
this function.
User Programmable Password — You may enter a
custom 4 number password for use in keeping pro-
gramming functions protected. When the feature is
enabled (function 55), you will be prompted to enter the
password. After that, anytime the user tries to access
the programming menu, they will be prompted for this
password.
UC2000 Charge Archive Function
The archive function allows up to 21 items of charge
cycle information to be retrieved and displayed. The
last 99 charge cycles are stored, with the most recent
cycle labeled #1 and earlier cycles labeled in ascending
order.
The most recent charger cycle data is moved to the #1
archive location when the next battery to be charged is
connected to the charger. At this time the all previous
archive cycle data is shifted to the next highest archive
location (1 to 2, 2 to 3, etc.).
The following key sequence is used to access charge
cycle archive data:
