ACU+ Controller (Advanced Control Unit Plus)

User Instructions, UM1M820BNA (Issue AK, March 3, 2014)

Spec. No: 1M820BNA, 1M820DNA Code: UM1M820BNA

Model No: M820B, M820D Issue AK, March 3, 2014

•

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.
