1.3 Function Descriptions

1.3.1 Rectifier Control

Rectifiers are automatically controlled by the ACU+ Controller. The ACU+ Controller provides an Energy Optimization Mode function. Energy Optimization permits an installation to only operate rectifiers as needed to maintain the load and keep batteries in a fully charged condition. As load increases, Energy Optimization turns on additional rectifiers as needed to maintain the load. As load decreases, Energy Optimization places rectifiers in standby to conserve energy usage. Rectifiers which are always operating to maintain any load requirements are cycled through the group of rectifiers controlled by this feature to provide uniform operating times for each rectifier.

1.3.2 Converter Control

Converters are automatically controlled by the ACU+ Controller.

1.3.3 System Components Monitoring and System Alarms Generation

The ACU+ Controller monitors the components comprising the system (such as the rectifiers, converters, and supervisory modules) and generates alarms if a fault condition occurs. The ACU+ Controller also maintains an alarm history log.

The available system alarms are programmed with an Alarm Severity Level. Each Alarm Severity Level has different visual/audible alarm attributes. Available Alarm Severity Levels and their attributes are listed in Table 1.

Table 1

Alarm Severity Levels

The alarm indicator turns OFF if the fault(s) that triggered the alarm clears. The audible alarm can be silenced by pressing any key on the ACU+ Controller local interface pad.

The audible alarm is also silenced if the fault(s) that triggered the alarm clears. An audible alarm cutoff feature can be programmed that silences the audible alarm after a pre-set

programmable time period. The audible alarm can also be disabled.

The available system alarms can also be mapped to alarm relays (located on ACU+ interface boards) that can be wired to external alarm circuits.

1.3.4 Operating Data Acquisition and Data Logs

The ACU+ Controller acquires and analyses real time data from the system’s components such as the rectifiers, converters, and supervisory modules.

The ACU+ Controller uses this data to process alarms and also records data in logs. The logs are viewed using the WEB Interface and consists of...

Alarm History Log: records 600 latest alarms. Data History Log: records 60000 latest history data. Control Log: records 500 latest control events. System Log: records 3000 latest system events. Diesel Test Log: records 500 latest diesel test results. Battery Test Log: up to twelve (12) battery discharge tests can be performed and recorded per year.

Note: Once maximum number of log entries is reached, new entries overwrite oldest entries.

Logs can be saved in the text (.txt) format.

Battery Charge Temperature Compensation

The ACU+ Controller can be programmed to automatically increase or decrease system output voltage to maintain battery float current as battery temperature decreases or increases, respectively. Battery life can be extended when an optimum charge voltage to the battery with respect to temperature is maintained. Temperature is monitored by a sensor mounted on the battery. See your power system documentation for temperature sensor information. You can also set High2, High1, and Low compensation temperature alarms.

Functional Description (See Figure 2): Battery charge temperature compensation adds a correction term, related to the temperature of the batteries, to the nominal value of the system voltage. The degree of regulation (TempComp Coeff), expressed in mV/°C/battery string, can be set per battery manufacturer recommendations.

To protect batteries and voltage-sensitive loads, compensation is automatically limited to a maximum of two volts (48V systems) or one volt (24 volt systems) above or below the nominal output level (float setting).

Temperature compensation will also clamp if the voltage reaches either the TEMP COMP MAX V setting or the TEMP COMP MIN V setting. This feature can also be disabled.

Temperature compensation is automatically disabled if communication between the Controller and all rectifiers is lost, a DC over or under voltage alarm activates, a low voltage disconnection occurs, manual mode is entered, or the system enters the boost or test modes.

Battery Equalize Charge and Battery Charge Current Limit

The ACU+ Controller can increase system output voltage for equalizing the charge on all battery cells of a conventional flooded cell battery, or for recharging the battery following a commercial power failure.

The charging function can be initiated cyclically (scheduled), automatically, or manually. Refer to the battery manufacturer's instructions for equalize charging instructions.

Functional Description (See Figure 3):

Start of Charging: When the battery charge current exceeds a preset value for 3 minutes or if the

calculated battery capacity has decreased to a preset value (after a commercial AC failure, for

example), the charging function of the ACU+ is activated. A charging signal is sent from the ACU+ to

the rectifiers to increase the voltage up to the battery charging level V

equalize

Battery Current Limitation: After a commercial AC failure or when some battery cells are

permanently damaged, the current to the batteries can be quite extensive. To avoid overheating or

further damages to the battery, the ACU+ limits the battery current to a preset level by limiting the

charging voltage of the rectifiers. Should the battery current still exceed a higher preset value, an

alarm is issued. End of Charging: When the charging current drops below a preset value, a defined prolonged

charging time is started before the charging is stopped and the voltage of the rectifiers return to the

float charging level (V

). For safety, there is a equalize charging limit time that stops the charging

nom

after a preset time.

Figure 3

Voltage Characteristics on Commercial AC Failure and Automatic Equalize Charging

High and Low Battery Temperature Alarms

The ACU+ Controller can monitor battery temperature via a temperature sensor mounted on a battery cell. Values for high battery temperature and low battery temperature alarms can then be programmed into the ACU+ Controller.

Battery Thermal Runaway Management (BTRM) Feature

You can designate a temperature sensor as the BTRM sensor. The BTRM sensor has High2 and High1 BTRM temperature alarm limits. If battery temperature exceeds the “BTRM Temp High2” setting, system voltage is lowered to the BTRM voltage setting. This feature can also be disabled.

Battery Discharge Test and Battery Test Logs

The ACU+ Controller can perform battery discharge tests to check the condition of the battery. There are (3) types of battery discharge tests.

Short Time Test Time Test Stable Current Test

A User can manually start a battery discharge test or program the ACU+ Controller to automatically start battery discharge tests at scheduled intervals (cyclic battery tests). During a battery discharge test, the ACU+ Controller controls the rectifiers output to place the entire load or partial load on the batteries. The ACU+ Controller monitors the discharge of the battery and saves the results in a battery test log.

Functional Description: For manual battery discharge tests as well as for cyclic battery discharge tests, the following parameters must be set: End Voltage, Test Time, and Battery Capacity Discharge Limit. See Figure 4.

Battery Discharge Test Sequence:

In time test modes, the output voltage of the rectifiers is reduced so that only the batteries power the

load. If the batteries fail, the rectifiers power the load. In stable current test mode, the output voltage of the rectifiers is reduced so that the batteries supply

the preset test current to the load. The battery test continues until one of the following occurs:

The preset test time, see Figure 4, expires. The battery has passed the test. The battery voltage drops below the preset end voltage level (V

) (Figure 4). The battery has not

end

passed the test and the test is interrupted. A battery test alarm is activated.

The battery capacity drops below the preset test end battery capacity. The battery has not passed

the test and the test is interrupted. A battery test alarm is activated.

After the battery discharge test, the output voltage of the rectifiers increase so that the rectifiers supply

the system and charge the batteries.

UM1M820BNA User Instructions Issue AH, March 4, 2013 Spec No. 1M820BNA (Model M820B) Spec No. 1M820DNA (Model M820D)

Battery LVD (Low Voltage Disconnect)

To prevent serious damage to the batteries during a commercial AC power failure, the batteries can be disconnected by voltage or time control.

The batteries are reconnected automatically when commercial AC power is restored and a predetermined DC voltage level is reached.

Voltage Controlled Disconnection: When the set voltage level is reached, the batteries are

disconnected. Time Controlled Disconnection: When the set time has elapsed, the batteries are disconnected.

Battery Capacity Prediction

The ACU+ can predict battery capacity.

Battery Block and Battery Midpoint Monitoring

The ACU+ can monitor battery blocks (12V blocks) or midpoint battery voltage of battery strings connected to the EIB assembly. An alarm is issued when either battery block voltage or battery midpoint voltage is abnormal.

Enhanced Battery Monitoring with SM-BRC

When connected to an SM-BRC, the ACU+ provides enhanced battery monitoring.

Thermal Runaway Detection and Management Functional Description: The system uses several control mechanisms to avoid thermal runaway.

First: During a short high rate discharge, the batteries will normally get hot. The ACU+ takes this into consideration. After completion of the discharge duty, the batteries are recharged with a limited current to avoid heating the batteries any further.

Second: The temperature of the batteries can be monitored, and the ACU+ sets the charge voltage appropriately, as previously described under Battery Charge Temperature Compensation.

Third: In addition to battery temperature compensation, if battery temperature rises above a set temperature limit, the system stops battery charging completely by lowering the output voltage to the “BTRM Voltage” setting. This allows the batteries to cool down. The system also provides alarm notification of this occurrence. Power supplied to customer equipment is not interrupted.

Fourth: The battery LVD circuits can be programmed to open (disconnect) if a high temperature event occurs (HTD – High Temperature Disconnect). The contactor(s) open when battery temperature rises above a programmable value and close again when battery temperature falls below another programmable value.

1.3.6 Intelligent Power Matching (Energy Optimization Mode)

With Energy Optimization Mode (ECO):

The Controller monitors load current versus system capacity. The Controller commands some rectifiers to standby in rotation.

1.3.7 Power Split Feature

The Power Split feature allows you to connect the power system controlled via the ACU+ to an existing DC power system instead of extending or completely replacing the existing DC power system.

The power system controlled via the ACU+ functions as a slave system to share load (split output) with the existing system (master system) that requires expansion. The ACU+ does not require communication with the master system’s Controller.

The Power Split feature provides for the sharing of total load in a controlled manner between the paralleled power systems.

When Power Split is programmed, the ACU+ adjusts rectifier output voltage per load demands to ensure proper sharing between the slave and master power systems. See Figure 5.

1.3.8 Diesel Management Feature

The Diesel Management feature is available when an SM-AC supervisory module is connected to the ACU+ Controller. The Diesel Management feature consists of a Diesel Test. The Diesel Test can be performed at specific intervals or a User can manually start the Diesel Test. The ACU+ records the test results.

1.3.9 PLC (Programmable Logic Controller) Function

The PLC function allows a User to create "control program lines" by combining equipment analog signals, parameters, and alarms in a sequence that controls equipment and/or operates relays.

Control program lines are created using the WEB Interface. See “4.8.6. PLC Sub-Menu”. Available logical components are:

1.3.10 Supervisory Module (SM Modules) Monitoring

Various devices (supervisory modules) can be connected to the ACU+ Controller to extend its monitoring capabilities.

1.3.11 Hybrid Control Function

Hybrid Control is designed for use in new installations or as an upgrade of existing sites powered by a diesel generator(s) when grid power is not available. The Hybrid Control is also applicable to sites with highly unreliable or frequently unavailable grid power connection. The primary power source is still considered to be the diesel generator(s).

Note: The Hybrid Control function requires a specific configuration. Hybrid Control menus will not

normally be displayed unless your ACU+ has been configured by Emerson for this function. Contact Emerson for a Hybrid Control configuration.

General

Hybrid Control allows the option of selecting one of the following: Fixed Daily Time based operation or Capacity Discharge based operation.

Systems, North America, Inc. Any copying, use, or disclosure of it without the written permission of Emerson Network Power, Energy Systems, North America, Inc. is strictly prohibited.

User Instructions UM1M820BNA Spec No. 1M820BNA (Model M820B) Issue AH, March 4, 2013 Spec No. 1M820DNA (Model M820D)

Fixed Daily Time based operation is intended to be used with a combination of AC powered active cooling (air conditioners) and DC powered cooling (heat exchangers, etc). The cycle period is synchronized to the 24hr day-night cycle. It makes optimum use of the different temperature conditions during the day and the night in order to facilitate Hybrid fuel saving operation.

Capacity Discharge based operation is intended for sites utilizing only DC powered cooling (heat exchangers, etc). The cycle period is determined by User selectable depth of discharge (DOD) of the batteries per cycle and associated recharge time. It provides optimum Hybrid fuel saving operation.

Operation from Grid Power is performed with both Fixed Daily Time and Capacity Discharge modes of operation. Grid power is always given priority when available.

As the two types of control are specific to the hardware configuration of the site, the Fixed Daily Time or Capacity Discharge is a User selectable option on installation.

Hybrid Operation Generator Control: Potential free relay contact output from the ACU+ interface board controls the start

and stop of the diesel generator. The signal is generated by the ACU+ Controller and operates according to the Hybrid software mode of operation. The control logic is as follows:

Energized output relay – Generator OFF. De-energized output relay – Generator ON.

This is a fail-safe logic to ensure generator operation in all cases where power or control to the relay is lost.

Further to that, the type of signal to the generator can be selected as N/O (Normally Open) or N/C (Normally Closed) by selecting the relevant output pins of the control relay.

Number of Generator Control Outputs: The ACU+ Hybrid software can control one or two generators. Each generator control is designated as DG1 or DG2 output. A User selectable menu will allow selecting DG1, DG2, or DG1 and DG2. When both are selected they will be alternatively used (two generator operation).

Diesel Fail Alarm: A diesel fail alarm will be generated if the Diesel Generator ON signal fails to bring the generator to operation and provide the system with AC power. Alarm will be triggered after 60 seconds (default value, settable) from ON signal. If two generator operations are selected simultaneously with the alarm, the second Diesel Generator ON signal will be activated.

Battery Fuse Trip Alarm: In the event of a Battery Fuse trip condition an alarm will be generated. Under Voltage Alarms:

Under Voltage Alarm 1: An Under Voltage Alarm 1 is set. If voltage decreases below this setting, an

alarm is raised. Under Voltage Alarm 2: An Under Voltage Alarm 2 is set. If voltage decreases below this setting, the

Diesel Generator is started and an alarm is raised.

LVD 1: Normal loads are disconnected. LVD 2: Priority loads are disconnected. Charge Voltage:

Figure 6

Charge Voltage

Equalize Charge: The battery will be recharged at equalize voltage. This is the voltage set in the initial phase of battery recharge. See Figure 6.

As the voltage limit is reached, the charge current is gradually reduced – effect known as current tail. When the current tail falls below a set of threshold levels, additional equalize charge time is added.

The equalize charge current tail threshold is settable from 0.01 to 0.05. Default setting is 0.02 (2A per 100Ah). The additional equalize charge time is settable from 0 hours to 7 hours (settable in minutes from 0 to 720), default setting is 4 hours. The duration of the equalize charge is determined as the time from the start of the recharge to the end of the additional time. (Maximum charge time, determined from the time charge starts, is settable in the range of 5-24h.)

The end of recharge is determined by a three (3) step approach:

Step1 - calculated battery capacity exceeds 90%. Calculation is performed by measurement of battery current and time, in Ah.

Step 2 - charge current tail threshold is reached.

Step 3 - additional charge time is added. Float Charge: Default float voltage is 54.0V at 20°C with a temperature compensation of -72mV per °C. If battery temperature exceeds 38°C, the charge voltage is reduced to 51V to reduce gassing and prevent

thermal runaway. The same is applicable as well for equalizing charge. Equalizing Charge: As the cyclic use does not ensure complete battery recharge after every cycle, an

equalizing charge cycle is added. The equalizing cycle will occur up to four times a month, settable for every 7 to 60 days intervals. Start date and time is settable. Equalizing charge time is 20 hours independent of discharge time setting. Equalizing charge is performed at equalize voltage until end of additional equalize time and thereafter at float voltage for the remaining time. Also see Figure 6.

Equalize charge independently settable 0-720 min (already set in equalize charge).

User Instructions UM1M820BNA Spec No. 1M820BNA (Model M820B) Issue AH, March 4, 2013 Spec No. 1M820DNA (Model M820D)

Early Termination of the Discharge Periods During discharge, over temperature and under voltage conditions will interrupt the discharge and

change the operation to charge – Diesel Generator ON. Over Temperature: The diesel generator will start and run for a period before it is stopped again. The run

time is User selectable in the range 30 to 120 minutes, default setting is 60 minutes. Temperature is referenced to cabinet/shelter ambient temperature sensor connected to the Controller, not battery temperature. Over temperature start can be disabled completely from User settings menu.

Under Voltage: The under voltage start is triggered by under voltage alarm 2 voltage settings. The diesel generator will start and run until the normal recharge cycle is due to finish depending on

selected mode of operation. Example for Fixed Daily Time: If the normal recharge cycle is from 7am until 7pm and under voltage has

started the diesel generator at 5:30am, the effective recharge will be from 5:30am until 7pm.

Example for Capacity Discharge: If this mode is selected, the recharge will terminate. Operation with Grid Power

Grid power is always prioritized when available. If grid power becomes available during battery discharge, the discharge cycle is terminated and recharge cycle is initiated. If grid power becomes available during diesel generator operation, the diesel generator is switched OFF and operations continue on grid power.

Battery Recharge with Grid Power: Battery recharge with grid power can start from the beginning (case of grid power becoming available during battery discharge) or can continue over from diesel generator recharge depending on the timing. In both cases, the recharge process will follow the recharge profile shown in Figure 6. If battery becomes fully recharged and grid power is still present, the operations will continue to be powered from grid and no battery discharge will be initiated for the duration of grid availability. In this case battery voltage will revert back to Float voltage.

Battery Discharge after Grid Failure: At the point of grid power failure, the battery capacity is unknown as these events occur in random manner. For the purpose of maximizing the use of grid power and in anticipation of grid power becoming available again, the Hybrid operation will continue with battery discharge cycle. Discharge will continue until:

The preset discharge time elapses (Fixed Daily Time). The preset DOD is reached (Capacity Discharge).

In both cases, the discharge can be terminated earlier as described in “Early Termination of the Discharge Periods”.

Relay 7: Diesel 1 in Operation

Output to DG1 on site. DG is set on for the duration of the signal.

Relay 8: Diesel 2 in Operation

Output to DG2 on site. DG is set on for the duration of the signal.

Fixed Daily

In this mode of operation the total duration of a complete cycle is 24hr. Such duration is necessary as the operation is synchronized with day-night temperature pattern. When an extended recharge cycle is required, the termination of it will still follow the 24hr schedule.

Cycle Duration: A complete cycle consists of discharge and charge periods to the combined total of 24hrs. The discharge period starts at 7pm. It is then followed by recharge period (Diesel Generator ON) for the remaining of the 24hrs. The discharge time is User selectable in the range 1hrs to 22hrs, default setting is 12hrs.

Discharge: The discharge start time and duration are settable. Discharge period starts at 7pm. The discharge time is User selectable in the range 1hrs to 22hrs, default setting is 12hrs.

Recharge: Recharge period (Diesel Generator ON) follows after discharge for the remaining of the 24hrs. Recharge is performed at equalize voltage until added equalize time elapses and at float voltage for the remaining charge time.

High Load Alarm: In order to identify conditions where the load requirements are exceeding the dimensioning of the Hybrid site, an alarm must be generated. The alarm will be triggered upon exceeding the maximum capacity per discharge cycle. The threshold value will be set as default to 40% of battery capacity. It will require capacity measurement per cycle. The alarm will be set once the high load threshold value is reached and is reset at the beginning of the next discharge period. This alarm will also allow distinguishing the root cause of under voltage conditions: is it high load demand or is it a battery ageing and associated loss of capacity issue or insufficient charge capacity.

Capacity Discharge

The cycle period is determined by User selectable capacity discharge of the batteries and associated recharge times. After that the cycle repeats itself. It does not follow a 24hr pattern.

Capacity Discharge and Recharge: The battery discharge period is determined by the percentage of the nominal battery capacity [Ah] that will be discharged per cycle.

The depth of discharge [DOD] per cycle is User selectable in the range 20% to 80%. Default setting is 60%. The value is set as battery capacity at the end of each discharge period. Therefore, if a 60% discharge is chosen, the discharge value is set to 40%.

The time to recharge to full battery capacity depends on battery capacity at the start of the charge cycle and available recharge current.

When the additional charge time has been reached; the generator will be stopped, the recharge cycle will end, and discharge cycle will be initiated.

For practical purposes, the battery capacity at the end of every recharge period is set to 100% as long as Step1, Step 2, and Step 3 have elapsed.

If end of charge is not reached within the set maximum hrs, the recharge will be terminated anyway and discharge cycle will be initiated.

1.3.12 Maximum Current Limit Function

The current available from the rectifiers can be programmed (in AMPS) from 10% to 121% of combined rectifier capacity. The factory setting is 121% unless otherwise specified. The current available from the converters can be programmed (in AMPS) from 50% to 116% of combined converter capacity. The factory setting is 116% unless otherwise specified. Refer to the ACU+ Configuration Drawing (C-drawing) supplied with your system documentation for your system’s settings.

If a rectifier or converter is added, the respective current limit point will automatically increase by the percentage each existing rectifier or converter was set to provide prior to the addition.

If a rectifier or converter is removed from the system (and the Rect Comm Fail or Conv Comm Fail alarm is reset), the respective current limit point will remain unchanged unless the capacity of the remaining rectifiers or converters is not sufficient to maintain the present current limit point. If that happens, the current limit point will automatically increase to the maximum (121% of the remaining rectifiers or 116% of the remaining converters).

2.5 Common Tasks Performed via the Local Keypad and/or Web Interface

Refer also to “Chapter 3. Local Display Menus” and “Chapter 4. WEB Interface Menus”.

2.5.1 Backing Up the Configuration

A file named “SettingParam.run” is automatically created/appended by the Controller whenever a User makes changes to any parameter settings via the LCD or WEB interface. This file can be saved to your computer so you can restore any custom settings you may have made.

Prior to changing settings, ensure the current “SettingParam.run” file is backed up. After making changes, create a new backup file.
