•
Fluct Range:
If load fluctuation is less than this value,
rectifiers are not turned on or off for Energy
Optimization.
•
Energy Save Pt:
Energy Optimization is disabled if
the load is greater than this setting.
•
Cycle Period:
This is the time period that rectifiers
are turned on and off to maintain an equal operating
time for all rectifiers in the system.
•
Rects ON Time:
Time all rectifiers are turned on at
End of Cycle.
•
Turn Off Delay:
When the Energy Optimization
feature determines a rectifier can be switched off,
this is the time delay before the rectifier is switched
off.
•
Input Curr Lmt:
Sets the Input Current Limit point for all
rectifiers.
•
MixHE Power:
Allows the system to use rectifiers of
different output capacity. When set to derated power,
the output capacity of the higher capacity rectifiers are
set to the capacity of the lowest.
•
DG Pwr Lmt:
Enables or disables the Diesel Power Limit
feature. This feature limits rectifier output power to a
percentage of maximum when AC input is supplied by a
diesel-alternator set.
•
Diesel DI Input:
Designates which digital input
controls operation of the Diesel Power Limit feature.
•
DG Pwr Lmt Pt:
Sets, as a percentage, the maximum
output power at which rectifiers can operate when:
1. the Diesel Power Limit feature is enabled and 2. a
digital input signal is received from the connected
diesel-alternator set.
•
Current Limit:
Enables or disables adjusting the output
current limit point.
Note:
By default this is set to disabled. When disabled,
rectifier current limit is set in the rectifier (not via
the ACU+) at the maximum current limit point.
•
Current Limit Pt:
Allows a User to set the output current
limit point when the “Current Limit” setting above is set
to enabled.
RECT #1 MENU
Menu Navigation:
Main Menu / Settings / Rectifier / Rect #1
Note: For WEB Interface; menu items are found under Device
Information / Rectifier Group / Rectifier #1 / Settings Tab.
"
Rect #1" Parameter Settings:
•
Rectifier ID:
Sets the rectifier position in the system.
•
Rect Phase:
Indicates the phase connected to the rectifier
input.
Battery
BASIC MENU
Menu Navigation:
Main Menu / Settings / Battery / Basic
Note: For WEB Interface; menu items are found under Device
Information / Battery Group / Settings Tab.
"Basic" Parameter Settings:
•
Num Batt Shunts:
Sets the number of battery shunts in
the system.
•
Calc Batt Curr:
Selects whether or not the ACU+
calculates the battery current in the case of no battery
shunt (load shunt required).
•
Low Capacity Pt:
Battery low capacity alarm set point.
•
Current Limited:
Enables or disables battery charge
current limit.
•
BTRM TempSensor:
Sets the BTRM (Battery Thermal
Runaway Management) temperature sensor. Note that
this temperature sensor MUST be set as a battery
temperature sensor. Select "None", or the temperature
probe (SMTemp8 T8 / ... / SMTemp8 T1 / ... / SMTemp1
T8 / ... / SMTemp1 T1 / EIB T2 / EIB T1 / IB2 T2 / IB2 T1).
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 BTRM sensor is the sensor which is used for the
High Temperature Disconnect (HTD) Feature.
•
BTRM Temp High2:
Allows you to set a high BTRM
temperature alarm 2 point. If battery temperature
exceeds the “BTRM Temp High2” setting, system voltage
is lowered to the “BTRM Voltage” setting (if BTRM Action
is enabled).
•
BTRM Temp High1:
Allows you to set a high BTRM
temperature alarm 1 point.
•
BTRM Action
•
Disabled:
Disables the Battery Thermal Runaway
Management feature.
•
Lower Voltage:
Sets the Battery Thermal Runaway
Management feature to reducing the output voltage
when battery temperature exceeds the BTRM Temp
setting.
