EQ Stop Delay:
See "EQ Stop Curr" above.
Note:
If the power system has been automatically placed
in Equalize mode, disabling Auto EQ will
not
return
the system to Float mode until the current Equalize
cycle is completed. To return immediately to Float
mode, navigate as follows: Main Menu / Manual /
Batt Group / EQ/FLT Control, and select Float
Charge.
•
Maximum EQ Time:
This is the maximum duration, in
minutes, that an Automatic Equalize Charge will last
regardless of the other settings.
•
Cyc EQ:
Enables or disables cyclic (scheduled) Equalize
charging. When enabled, the following parameters can
be set.
•
Cyc EQ Interval:
Cyclic (scheduled) Equalize charging
interval.
•
Cyc EQ Duration:
Cyclic (scheduled) Equalize
charging duration.
Temp Comp
TEMP COMP MENU
Menu Navigation:
Main Menu / Quick Setting / Temp Comp
Note: For WEB Interface; menu items are found under Quick
Settings / Temp Compensation Setting.
"Temp Comp" Parameter Settings:
•
Temp CompCenter:
Sets the temperature at which the
system operates at normal voltage levels.
•
Temp Comp Coeff:
Sets the temperature compensation
slope or rate of change per °C above or below the "Temp
Comp" setting. This value is expressed in millivolt per °C
per string (mV/°C/str). For example, for a rate of change
of
72 mV/
°
C/str
in a 24-cell 48V nominal battery string,
the rate of change is 3 mV per cell.
•
TempComp Sensor:
Select "None" for no temperature
compensation, or the temperature probe (SMTemp8 T8 /
... / SMTemp8 T1 / ... / SMTemp1 T8 / ... / SMTemp1 T1 /
EIB T2 / EIB T1 / IB2 T2 / IB2 T1) sensing battery
temperature for temperature compensation. You can
also select Maximum or Average which takes the
maximum or average reading of the temperature probes
(any of SMTemp8 T8 / ... / SMTemp8 T1 / ... / SMTemp1
T8 / ... / SMTemp1 T1 / EIB T2 / EIB T1 / IB2 T2 / IB2 T1) set
as battery temperature probes. When used with an SM-
BRC, you can select to average the SM-BRC temperature
probe readings.
Note:
The temperature compensation sensor is also the
sensor which displays the battery temperature on
the Web Interface’s Homepage.
•
Comp Temp High2:
Allows you to set a high
compensation temperature alarm 2 point.
•
Comp Temp High1:
Allows you to set a high
compensation temperature alarm 1 point.
•
Comp Temp Low:
Allows you to set a low compensation
temperature alarm point.
•
Temp Comp Clamp:
Enables or disables the temperature
compensation voltage clamp feature.
•
Temp Comp Max V:
Upper voltage limit where battery
temperature compensation clamps the voltage.
•
Temp Comp Min V:
Lower voltage limit where battery
temperature compensation clamps the voltage.
Rectifier Expansion
RECTIFIER EXPANSION MENU
Up to four (4) ACU+ Controllers can be connected together when a
power system requires a greater number of rectifiers than can be
controlled by a single ACU+ Controller. One (1) Controller is
designated as the primary Controller, the others as secondary
Controllers. The rectifiers controlled by the secondary Controllers
are designated as RectifierGroup 2 through 4 in the menus.
Primary/Secondary Procedure:
Note:
Changing the Rectifier Expansion setting may take more than
3 minutes for the ACU+ to configure the feature.
1. Connect the ACU+ Controllers in the multiple bays via the
RS485 interface.
2. Set one of the ACU+ Controllers as the Primary Controller
(see below).
3. Set all other ACU+ Controllers as Secondary Controllers
(see below).
4. Set the Address of the ACU+ Controllers set as Secondary
Controllers to 201, 202, or 203 (see below). Note that
each Secondary Controller must be set to a different
address.
