the battery temperature throughout the charge
cycle. Programming the MAX BATT TEMP setting
of the control to the desired maximum battery
temperature will cause the charger to shut down if
the battery on charge is equipped with a BID and
the temperature exceeds the set point. It will wait
until the battery temperature has decreased to
5 degrees C below the set point before restarting
the charge cycle.
Charge Termination — The EC2000 utilizes a
patented proportional time DV/DT technique in order
to determine the charge termination point. This tech-
nique returns approximately 107% of the amp hours
removed from a battery (regardless of the state of
discharge) and prevents variations in the incoming
AC line voltage from affecting the amount of Energy
returned to the battery. The minimum time required
for a DV/DT charge termination on the EC2000
Control is fifteen minutes. The EC2000 Control can
be programmed to utilize a voltage-time charge
termination technique. If the DV/DT charge termina-
tion is disabled, the control will terminate the charge
cycle four hours after the battery reaches the “80%
Charged” point.
Alphanumeric Display — A backlit liquid crystal
(LCD) 2x20 character display is standard on the
EC2000 Control. The characters are .2 inches tall,
making the information on the digital display legible
at distances exceeding five feet. Plain English and
easy to understand abbreviations are used to
indicate charge status output current and voltage
and other functions including; archive information,
review information, programming information, fault
information, and operating status. A blank display is
utilized for AC power fail indication.
Status Display LEDs — The “Charge In Progress”
LED (Amber) is illuminated whenever the charger is
flowing current to the battery. There are four status
LEDs provided to indicate the present operating
status of the charger and battery (see Figure 7-1). A
lamp test feature is provided. See Review of Charge
Cycle feature.
Review of Charge Cycle — When the charge cycle
is in progress or has been terminated, either by the
EC2000 Control or the operator, the charge cycle
history can be automatically read out by pressing
the “Cycle Review” key. After displaying the infor-
mation from memory, the unit will return to the
normal (previous) display.
All status LEDs will be Illuminated during the review
of function number one, thus providing a lamp test
feature. Nine functions are displayed during a stand-
ard review. If the charger is idle, the information in
all 58 review functions can be displayed. See the
EC2000 Charge Cycle Review Feature section in
this chapter. A single item can be selected by
pressing the appropriate labeled key. This feature
can greatly aid in the analysis of charge data and in
situations where troubleshooting is required. See
the Troubleshooting chapter in this manual.
Automatic or Push-to-Start Operation — In the
automatic start mode, the charger will start 5-15
seconds after the battery is connected. The alpha-
numeric display will display “READING BID” and
then display upcoming cycle information. In the
push-to-start mode, the charger will not start the
charge cycle until the “Enter” key is pressed. “Ent to
Start Charge” will be displayed on battery connect
when this feature has been selected.
Manual or Automatic Equalize — An equalize
charge is a prolonged charge cycle (by 3 hours)
used to correct any inequalities of voltage and
specific gravity which may have developed between
the cells during service. EC2000 Controls are
shipped from the factory with the automatic equalize
feature enabled. This mode of operation is indicated
in the full Review “AUTO EQ. ON” function. There
are three modes of automatic equalize. See the Au-
tomatic Equalize section in this chapter for further
details. When the automatic equalize feature is
active, the “Equalize” key on the front panel is
disabled. When automatic equalize is disabled, an
equalize charge is requested by pressing the
“Equalize” key on the front panel of the EC2000
Control during countdown or after the charge cycle
has started. If this key is pressed again during the
charge cycle, the equalize request will be canceled
if the equalize period has not begun.
Fault Lockout Operation — In the normal
operating mode (No fault lock-out), if an abnormal
shutdown occurs, disconnecting and reconnecting
the battery will clear the fault and the EC2000 will
restart the charge cycle as programmed. If an
abnormal shutdown occurs with the fault lock-out
feature enabled, disconnecting and reconnecting a
battery will not clear the fault condition.
The alphanumeric display will display fault lockout,
and the status LEDs will continue to flash even with
no battery connected to the charger until the fault
condition is cleared. The “Enter” key will clear the
fault if it is pressed while a battery is not connected
to the charger.
One Part Number Control — The standard
EC2000 Control is user/factory programmable for 6,
9, 12, 18, 24, 36, and 40 cell Eclipse II Pluses with
100, 200, 400, and 600 amp shunts. Any combina-
tion of the above cell sizes and current shunt sizes
can be selected by DIP switches on the P.C. board.
This feature reduces the quantity of spare parts in-
ventory. See Figure 8-1 for further information.
Refresh Charge Feature — A refresh charge of a
storage battery is a charge given to charged, wet
