1 Introduction

1.1 Preface

These instructions describe the complete functionality of the NetSure Control Unit (NCU). Some functionality is dependent on hardware connected to the NCU. Your system may not utilize all the functionality described.

Refer also to the NCU Configuration Drawing (C-drawing) furnished with your system for a list of factory default settings.

1.2 Overview

The NCU performs the following functions:

• Rectifier Control, including an Energy Optimization Mode

• Solar Converter and Converter Control

• System Components Monitoring and System Alarms Generation (including recording alarms in logs)

• Operating Data Acquisition and Data Logs

• Battery Management

• Energy Management via Energy Optimization Mode

• Power Split Feature

• AC Generator Function

• Diesel Management Feature

• Hybrid Control Function (Supporting Generator, Solar and Wind Energy Input, and Optimization).

• Supervisory Module (SM Modules) Monitoring

• Maximum Current Limit Function

• Communications Function

• FIAMM SoNick (Sodium Nickel) Battery Interface

• Radius Server Feature

The NCU controls the system automatically via configured parameters.

A User can interface with the NCU locally using the local keypad and display or locally/remotely using the Web Interface.

The NCU can also be accessed via SNMP (v2 and v3) or TL1 (over Ethernet). A machine-to-machine HTTP interface is also available.

Figure 1-1 illustrates the various applications that can be used to interface with the NCU.

Figure 1-1: Interfacing with the NCU

1.3 Function Descriptions

1.3.1 Rectifier, Solar Converter, and Converter Control

The NCU controls rectifiers, solar converters, and converters automatically.

1.3.2 System Components Monitoring and System Alarms Generation

The NCU monitors the components comprising the system (such as the rectifiers, solar converters, converters, and supervisory modules) and generates alarms if a fault condition occurs. The NCU 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 1-1.

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

NOTE!

Solar Mode has to be enabled for NCU control of solar converters (see “Enabling Solar Mode” on page 38).

oldest entries.

1.3.4 Battery Management

The NCU provides the following battery management functions.

• Battery Charge Temperature Compensation

Page 14

Vertiv™ NetSure™ Control Unit (NCU) User Manual

• Battery Equalize Charge

• Battery Charge Current Limit

• High and Low Battery Temperature Alarms

• Battery Thermal Runaway Management (BTRM) Feature (Reduces Voltage during a High Battery Temperature Condition)

• Battery Discharge Test

• Battery Test Logs (maximum ten [10] tests saved)

• Battery LVD (Low Voltage Disconnect)

• Battery Capacity Prediction

• Battery Block and Battery Midpoint Monitoring

• Thermal Runway Detection and Management

NOTE!

Battery management functions are not available for NCU configurations that enable NCU capability to receive status

information sent from FIAMM SoNick (Sodium Nickel) batteries.

Battery Charge Temperature Compensation

The NCU 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 high and low compensation temperature alarms.

Functional Description (See Figure 1-2):

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 can be set to clamp lower than this by enabling the Temperature Compensation Clamp feature. When enabled, temperature compensation will clamp if the battery temperature reaches either the Temp Comp Max Voltage setting or the Temp Comp Min Voltage setting.

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 equalize or test modes.

Refer to “Specifications” on page 259 for temperature probe and reading accuracy.

Battery Equalize Charge and Battery Charge Current Limit

The NCU 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 1-3):

• Start of Charging: When the battery charge current exceeds a preset value for three (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 NCU is activated. A charging signal is sent from the NCU 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 NCU 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. Battery charge current is limited to the value set in the controller, as long as battery voltage is above 47 VDC.

• 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 equalized charging limit time that stops the charging after a preset time.

). For safety, there is an

Vertiv™ NetSure™ Control Unit (NCU) User Manual

High and Low Battery Temperature Alarms

The NCU 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 NCU.

Battery Thermal Runaway Management (BTRM) Feature

The Battery Thermal Runaway Management (BTRM) feature reduces voltage during a high battery temperature condition.

You can designate a temperature sensor as the BTRM sensor. The BTRM sensor has High 2 and High 1 BTRM temperature alarm limits. If battery temperature exceeds the “BTRM Temp High 2” setting, system voltage is lowered to the BTRM voltage setting. This feature can also be disabled.

Battery Discharge Test and Battery Test Logs

The NCU can perform battery discharge tests to check the condition of the battery(s). There are three (3) types of battery discharge tests:

• Battery Test without Constant Current

• Battery Test with Constant Current

• Short Time Test (requires two battery shunts)

A User can manually start a battery discharge test or program the NCU to automatically start battery discharge tests at scheduled intervals. Twelve (12) Constant Current Tests can be scheduled by the month-day-hour. A Short Time Test can be scheduled to be performed every 1-365 days. During a battery discharge test, the NCU controls the rectifiers output to place the entire load or partial load on the batteries. The NCU monitors the discharge of the battery and saves the results in a battery test log. The NCU stores ten (10) battery discharge tests.

Functional Description:

For manual battery discharge tests as well as for scheduled battery discharge tests, the following parameters must be set: End Test Voltage, End Test Time, and End Test Capacity. See Figure 1-4.

Figure 1-4: Battery Test Diagram

Battery Discharge Test Sequence:

• For a Constant Current Test, the output voltage of the rectifiers is reduced so that the batteries supply the preset Constant

Current Test Current to the load.

• If Constant Current is disabled, then the current being delivered by the batteries will be dependent on the load.

• For a Short Time Test, 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.

• The battery test continues until one of the following occurs:

- The preset End Test Time, see Figure 1-4, expires. The battery has passed the test.

- The battery capacity drops below the preset End Test Capacity. The battery has passed the test.

Page 17

Vertiv™ NetSure™ Control Unit (NCU) User Manual

- The battery voltage drops below the preset End Test Voltage (Vend) (see Figure 1-4). The battery has not passed the

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

- If a critical alarm occurs during the test or there’s not enough load, the battery test is aborted. In such cases a “Battery

Test Fail” alarm will be activated (indicating the test couldn’t be done). This alarm is different from the “Bad Battery” alarm (meaning the test was completed but the battery didn’t pass it).

• A battery test alarm is active during a battery discharge test.

• If the battery has not passed the test, a bad battery alarm is activated.

• After the battery discharge test, the output voltage of the rectifiers increases so that the rectifiers supply the system and

charge the batteries.

NOTE!

A procedure for performing a manual battery discharge test is provided on page 47.

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.

See “LVD Tab Programmable Parameter Descriptions” on page 150 for descriptions of programmable LVD parameters.

Battery Capacity Prediction

The NCU can predict battery capacity. When a battery is connected to the system at initial setup or increasing the number of batteries, you need to update the Battery Ah rating. After doing this and making sure the battery is fully charged you need to reset the battery capacity used percentage by performing the “Reset Battery Capacity” command to tell the NCU that the batteries are 100% charged. From this point forward the NCU will keep track of the battery current and time to predict the battery capacity used.

Battery Block and Battery Midpoint Monitoring

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

Thermal Runaway Detection and Management

Functional Description:

The system uses several control mechanisms to avoid thermal runaway.

• During a short high rate discharge, the batteries will normally get hot. The NCU 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.

• The temperature of the batteries can be monitored, and the NCU sets the charge voltage appropriately, as previously

described under “Battery Charge Temperature Compensation” on page 4.

• 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. See “Setting Battery Thermal Runaway Management (BTRM) Feature” on page 40 for programming.

• 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. See “LVD Tab Programmable Parameter Descriptions” on page 150 for programming.

1.3.5 Energy Management

Energy Management consists of an Energy Optimization Mode.

Energy Optimization Mode

The NCU provides an Energy Optimization Mode (ECO) 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.

ALERT! The Energy Optimization Mode should NOT be used in systems that operate without batteries.

The following operating conditions apply:

NOTE!

If the battery is ever disconnected, disable Energy Optimization Mode until the battery is reconnected.

1. The ECO mode is only enabled upon normal system operation. If any of the following alarms occurs, the system cannot enter

or will exit the ECO mode.

a) Current imbalance (only when imbalance current protection is enabled).

b) AC fail.

c) Any one rectifier over temp.

d) Any one rectifier AC fail.

e) Any one rectifier fault.

f) Any one rectifier over voltage.

g) Any one rectifier fan fault.

h) Any one rectifier no response.

i) Any one battery fuse open.

j) Any one LVD disconnect.

k) Battery is in charge or discharge, as defined below:

- Battery current > [battery rated capacity × 0.005], or battery current > 5A means battery in charge.

- Battery current < [battery rated capacity × -0.003], or battery current < -2A means battery in discharge.

l) Under voltage.

m) Any one rectifier in current limit mode.

2. The system load cannot exceed the system energy saving point (default value is 45%). Otherwise the system cannot enter or

will exit the ECO mode.

3. When the rectifier load exceeds its optimal operating point, the system will exit the ECO mode and the controller will

recalculate and then turn off any unnecessary rectifiers. After that, the system can enter the ECO mode again.

Page 19

Vertiv™ NetSure™ Control Unit (NCU) User Manual

4. If the system enters the ECO mode and then exits for five consecutive times within one hour, an abnormal alarm (ECO Cycle

Alarm) will be generated and the system can no longer enter the ECO mode until the ECO Cycle Alarm is cleared manually or retires automatically after 24 hours.

1.3.6 Power Split Feature

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

The power system controlled via the NCU functions as “System A” to share load (split output) with the existing system (“System B”) that requires expansion. The NCU does not require communication with the “System B’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 NCU adjusts rectifier output voltage per load demands to ensure proper sharing between “System A” and “System B”. See Figure 1-5.

Figure 1-5: Power Split Feature

1.3.7 AC Generator Function

This is a special feature to control an AC generator using the NCU controller by either a voltage threshold or a battery capacity threshold. The control occurs from a User designated relay located on the IB2 or EIB board. When this generator relay is activated, this means the generator should turn “On”. Criteria for the generator function is to start the generator when either the output voltage (AC Generator Start Voltage setting) or battery capacity (AC Generator Start Capacity setting) decreases to the set point. Once this occurs, an alarm called “Automatic AC Generator Run” is activated, the relay changes state, and the generator is told to start. The generator runs for a period of time and is then turned off after the Auto Equalize feature of the controller finishes.

Page 20

Vertiv™ NetSure™ Control Unit (NCU) User Manual

Auto Equalize looks for two (2) specific conditions for activation.

1. Has the recharge current (provided either by the rectifiers or solar converters) exceeded a User settable Equalize Start

Current value for three (3) minutes or

2. Has the battery capacity decreased to a User settable value.

If either of the above conditions are reached, Auto Equalize activates and the NCU controller tells the rectifiers and solar converters (if present) to provide their respective output equalize voltages. Auto Equalize will deactivate once the battery recharge current reaches the Equalize Stop current level and the Equalize Stop Delay has been satisfied. Once equalize has finished, the generator will also shut off if it is running.

In addition to the automatic features above, this Generator Function will provide a way to manually run the generator when necessary. Although not necessary for operation, the function will also have the capability for recognizing a digital input signal that can be used to send feedback to the controller that the generator is running.

See “AC Generator Function:” starting on page 143.

1.3.8 Diesel Management Feature

The Diesel Management feature is available when an SM-AC supervisory module is connected to the NCU. 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 NCU records the test results.

1.3.9 Hybrid Control Function (Supporting Generator, Solar and Wind Energy Input, and

Optimization)

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). Since grid power is always given priority, the primary power source is still considered to be the grid power.

General

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

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 24hrs 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.

NOTE!

The Hybrid Control function requires a specific configuration. Hybrid Control menus will not normally be displayed

unless your NCU has been configured by Vertiv for this function. Contact Vertiv for a Hybrid Control configuration.

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.

Page 21

Vertiv™ NetSure™ Control Unit (NCU) User Manual

Hybrid Operation

Generator Control: A potential free relay contact output from the NCU interface board controls the start and stop of the diesel

generator. The signal will be generated by the NCU and operates according to the Hybrid software mode of operation. The default control logic (User selectable) 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 relays is lost.

In addition, 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 NCU Hybrid software can control one or two generators. Each generator control is designated as DG1 or DG2 output. The User can select DG1, or DG2, or DG1 and DG2. When both are selected they will be alternatively used (two generators 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 operation is selected, the second Diesel Generator ON signal will be activated simultaneously with the Diesel Fail alarm.

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: If voltage decreases below the Under Voltage Alarm 1 setting, an alarm is raised.

• Under Voltage Alarm 2: If voltage decreases below the Under Voltage Alarm 2 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: Refer to Figure 1-6.

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

recharge. See Figure 1-6.

As the voltage limit is reached, the charge current is gradually reduced – this effect is known as current tail. When the current tail falls below a threshold level, additional equalize charge time is added and then the recharge ends.

The equalize charge current tail threshold is settable from 0.002 to 0.02. Default setting is 0.01 (1 A per 100 Ah). The additional equalize charge time is settable from 1 hour to 24 hours (settable in minutes from 0 to 1440), default setting is 3 hours. The duration of the equalize charge is 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 1 hour to 48 hours, default setting is 18 hours).

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 completed.

Page 22

Vertiv™ NetSure™ Control Unit (NCU) User Manual

Float Charge: Default float voltage is 54.0 V at 20°C with a temperature compensation of 72 mV per °C.

If battery temperature exceeds the BTRM Temp High 2 alarm set point, the charge voltage is reduced to 48 V to reduce gassing and prevent thermal runaway. The same is applicable as well for equalizing charge.

Equalizing Charge Cycle: As the cyclic use does not ensure complete battery recharge after every cycle, an equalizing charge cycle is added. The equalizing cycle is settable for every 2 to 365 days intervals, default setting is 100 days. Equalizing charge time is 12 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 1-6.

Equalize charge independently settable 0-1440 min (already set in equalize charge).

Figure 1-6: Charge Voltage

Early Termination of the Discharge Periods

During discharge, over temperature and under voltage conditions will interrupt the discharge and change the operation to charge with the 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 controller, not battery temperature. Over temperature start can be disabled completely from the 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.

Under Voltage with 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.

Under Voltage with Capacity Discharge: If this mode is selected, the recharge will terminate.

Operation with Grid Power

Grid power is always used 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 (when grid power becomes available during battery discharge) or can continue from diesel generator recharge, depending on the timing. In both cases, the

Page 23

Vertiv™ NetSure™ Control Unit (NCU) User Manual

recharge process will follow the recharge profile shown in Figure 1-6. 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” on page 12.

Relay Assignment – when in Hybrid Mode

Relay 1: Generator Alarm.

No Generator Voltage Alarm. No AC supply, 60 sec delay.

Relay 2: Battery Alarms. Logic alarm generated from: under voltage 1, under voltage 2, LVD1, LVD2, battery high temp, battery very high temp, overvoltage 1, overvoltage 2, battery temp sensor fail, battery fuse alarms and high load alarm.

Relay 3: Rectifier Alarms. Logic alarm generated from: multiple rectifier fail, rectifier fail, rectifier fan failure, rectifier HVSD, rectifier AC failure and rectifier not responding.

Relay 4: System Alarms. Logic alarm generated from: load fuse alarms, high ambient temperature, ambient temp sensor fail; smoke detected, and water detection.

Relay 5: Generator Run at High Temp. Output to intelligent cooling devices linked to AC supply (DG run).

Relay 6: Intruder Alarm. Alarm triggered by dry contact door/motion sensor.

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 24hrs. This duration is necessary as the operation is synchronized with day-night temperature pattern. When an extended recharge cycle is required, its termination will still follow the 24hrs schedule.

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

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

Page 24

Vertiv™ NetSure™ Control Unit (NCU) User Manual

High Load Alarm: In order to identify conditions where the load requirements are exceeding the dimensioning of the Hybrid site, an alarm will be generated. The alarm will be triggered when the maximum capacity per discharge cycle is exceeded. 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 help the User identify the root cause of the under voltage condition: high demand load, the loss of capacity due to battery aging, or insufficient charge capacity.

Capacity Discharge

The cycle period is determined by User selectable capacity discharge of the batteries and associated recharge times. The cycle repeats continuously. It does not follow a 24hrs 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 the 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 hours, the recharge will be terminated and discharge cycle will be initiated.

1.3.10 Supervisory Module (SM Modules) Monitoring

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

1.3.11 Maximum Current Limit Function

The current available from the rectifiers can be limited (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 NCU Configuration Drawing (C– drawing) supplied with your system documentation for your system’s settings.

See also “Checking the Controller’s Current Limit Point after Adding or Removing a Rectifier or Converter Module” on page 37.

1.3.12 Communications Function

The NCU is able to communicate with different equipment or, connect to different equipment for communication. See Figure 1-7.

a) 10M/100M Ethernet Port: The NCU can communicate with a supervisory computer or other devices through its 10M/100M

Ethernet port. The communication cable shall be a shielded cable. The Ethernet port is located on the front panel of the NCU. This port supports Dynamic Host Configuration Protocol (DHCP) function.

NOTE!

Some systems may have an IB4 board with a second Ethernet port. The IB4 board is connected to the NCU’s

backplane connector (USB) via a factory provided cable. Refer to your system’s documentation for location of the IB4 board

(if furnished).

b) IB2 (Interface Board) and EIB (Extended Interface Board): Some systems may have an IB2 (Interface Board) and/or EIB

(Extended Interface Board) connected to the NCU. Each IB2 board provides eight (8) dry relay outputs. Each EIB board provides five (5) dry relay outputs. Every relay output has a set of NC (normally close) and NO (normally open) contacts.

Page 25

Vertiv™ NetSure™ Control Unit (NCU) User Manual

The relay outputs can be connected to customer external alarm circuits. Each relay output can be configured to change state when one or more alarm events occur.

The relay outputs can also be connected to customer external equipment, so that the relay output can control or interface with the customer external equipment.

c) IB4 (Interface Board 4): Some systems may have an IB4 board. The IB4 board is a USB to LAN converter for the NCU, which

includes a USB and an Ethernet port. The IB4 board is connected to the NCU’s backplane connector (USB) via a factory provided cable. Refer to your system’s documentation for location of the IB4 board (if furnished).

d) RS-485 Port: The NCU can communicate with an SM-AC, SM-Bat, or SMIO through the RS-485 port. The RS-485 port uses

the parameters 19200, n, 8, 1.

e) Modbus Protocol: The NCU can communicate with an AC Meter using the Modbus protocol.

f) TL1: See “TL1 Interface” starting on page 59.

g) Machine-to-Machine HTTP Interface: See “Machine-to-Machine HTTP Interface” starting on page 60.

1.3.13 FIAMM SoNick (Sodium Nickel) battery Interface

If a special configuration file is furnished, the NCU has capability to receive status information sent from FIAMM SoNick (Sodium Nickel) batteries. See “FIAMM SoNick (Sodium Nickel) Batteries Interface” starting on page 57.

Figure 1-7: The Controller Perspective

1.3.14 Radius Server Feature

When the radius server feature is enabled and a User attempts to login using the LCD or web page, the NCU first checks the username/password entered for a match programmed in the NCU. If the NCU authenticates, then the NCU grants the User access. This step is to allow a login in case the radius server is not available, has changed, etc.

If the authentication fails (either not present or wrong password), then the NCU checks the username/password entered using the radius interface. If the NCU authenticates, then the NCU grants the User access. If authentication fails, the NCU notifies the User and does not grant the User access.

If an IB4 board is present, the radius messages are sent to the IB4 network interface; otherwise, the radius messages are sent to the front (craft) port.

2.9.32 Checking the Controller’s Current Limit Point after Adding or Removing a Rectifier

or Converter Module

If a rectifier or converter module is added; the respective current limit point in amps will automatically increase to maintain the same percentage. For example, if the current limit was set to 100% of combined capacity and a module is added, the new current limit setpoint will be 100% of the combined capacity including the new module.

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

It is recommended that the current limit point be checked whenever a rectifier or converter module is added to or removed from the power system.

When setting total rectifier or total converter current limit, the set point to each unit is the total set point divided by the number of units. For example, if the system contains five rectifiers and the current limit is set to 150 amps then each rectifier has a current limit set point of 30 amps. If one or more rectifiers or converters are removed or fails, it will take several seconds for the individual set points to the remaining rectifiers or converters to be reset. In the example given, if one rectifier is removed the current limit set point will drop to 120 amps (30 amps times four remaining rectifiers) until the controller can send updated set points to the remaining rectifiers. This takes a couple communication cycles (several seconds) after which each rectifier would have a new set point of 37.5 amps for a total of 150 amps. The total current limit of the rectifiers and converters should not be set such that the loss of the redundant rectifiers or converters will cause this temporary set point to drop below the actual maximum expected load. If batteries

Page 48

Vertiv™ NetSure™ Control Unit (NCU) User Manual

are used on the rectifier output, the batteries should support the load until the current limit set points can be re-established due to loss of a rectifier.

2.10 Power Split Feature

In Power Split applications, the output of the power system controlled by the NCU can be connected in parallel with an existing power system. Each system is controlled independently via its own controller. The NCU power system is referred to as "System A" and the existing power system as “System B”. The Power Split feature controls the NCU power system’s (“System A”) output voltage and rectifiers' current limit so that “System A” shares the load with “System B”.

Optional Functions: The NCU controller can mimic the equalize and battery test functions of “System B’s” controller. In addition, the NCU controller can mimic the low voltage load disconnect and/or low voltage battery disconnect functions of “System B”. This is accomplished by supplying digital signals from “System B’s” controller to the NCU. This allows these functions to remain active in “System B”.

2.10.1 Overview

See also “Power Split Feature” on page 9.

How Power Split Works

There are four User adjustable parameters for Power Split. They are:

• Power Split Current Limit Value: Current limit point for power system designated as “System A” in a "Power Split"

configuration.

• Delta Voltage: The offset voltage that the power system designated as “System A” in a "Power Split" configuration is set to.

It is suggested to leave this value at the default (0.5 volts).

Page 62

Vertiv™ NetSure™ Control Unit (NCU) User Manual

• Proportion Coeff: The proportional coefficient that the power system designated as “System A” in a "Power Split"

configuration is set to. It is suggested to leave this value at the default (30%).

• Integral Time: The integral time that the power system designated as “System A” in a "Power Split" configuration is set to. It

is suggested to leave this value at the default (60 seconds).

The NCU controller uses these parameters to control the load sharing operation between the two power systems.

Depending on the systems’ configurations, their rectifier capacities, their distribution load capacities, and the Power Split configuration; four operating modes can occur.

Low Load Operation

When the total load current demand is lower than the Power Split Current Limit Value, the NCU power system voltage will be increased by the programmed DELTA VOLTAGE setting forcing the NCU power system to carry the load. Make sure that the output voltage does not exceed the battery float range recommended by the manufacturer. In this operating mode, no current will be delivered by the existing power system.

Normal Load Operation

When the total load current demand reaches the Power Split Current Limit Value, the NCU power system operates in output current limit and its output voltage will be decreased (up to the DELTA VOLTAGE setting) in order to regulate the current, allowing the existing power system to deliver the remaining current. Both the NCU power system and the existing power system are now providing current to the load.

High Load Operation

If current demand increases and the existing power system reaches its current limit setting, float voltage will again begin to decrease. When the voltage falls below the float setting minus the DELTA VOLTAGE setting, the NCU system will come out of current limit and now deliver the additional current necessary to satisfy the load. This operation may occur when the batteries are being recharged, such as after a commercial AC failure.

Over Load Operation

If the load current is greater than the combined current capacities of the NCU system and the existing power system, both power systems will go into current limit. Both systems and the batteries will feed the load. The output voltage will depend on the conditions of the batteries. This operation occurs if the total capacity of the rectifiers is too low in relation to the need for increased current.

Operating Modes

Figure 1-5 illustrates the four modes of operation described above.

The Normal Load Operation is considered to be the normal mode. In this mode both the NCU system and the existing parallel power system are both delivering load current. This is main purpose of using Power Split, to avoid putting the burden of delivering the entire load onto one of the two power systems.

Requirements and Conditions

The two DC power systems must be connected in parallel as described in “Paralleling the Existing and NCU Power Systems” on page

53.

Before paralleling the two systems, the following conditions must be met for proper Power Split function.

NOTE!

The control features of the combined system are limited to those of the original power system.

NOTE!

The same type of batteries with an equal amount of cells and the same charging voltages must be used for both

systems.

Page 63

Vertiv™ NetSure™ Control Unit (NCU) User Manual

• The float voltage, equalize voltage, and battery test voltage of the NCU power system must be set to the same levels as that

of the existing power system.

• The remote sense, if available and connected, of both the NCU power system and existing power system must be connected

to the same point.

• If batteries are used, they must be of the same type.

• All the functions specific to the existing power system and NCU power system and which depend on the voltage or which act

on the voltage must be disabled from the existing power system and NCU power system. This includes the following…

a) any equalization function,

b) any temperature compensation function,

c) any charge control function,

d) any battery discharge test function, and

e) any invalid current alarm.

In lieu of this, if battery charging and battery test functions are implemented in the existing power system, they can remain if signals for starting are connected from the control system of the existing system to the NCU system.

Important Safety Instructions

General Safety

DANGER! YOU MUST FOLLOW APPROVED SAFETY PROCEDURES.

Performing the following procedures may expose you to hazards. These procedures should be performed by qualified

technicians familiar with the hazards associated with this type of equipment. These hazards may include shock, energy,

and/or burns. To avoid these hazards:

a) The tasks should be performed in the order indicated.

b) Remove watches, rings, and other metal objects.

c) Prior to contacting any uninsulated surface or termination, use a voltmeter to verify that no voltage or the expected

voltage is present. Check for voltage with both AC and DC voltmeters prior to making contact.

d) Wear eye protection.

e) Use certified and well maintained insulated tools. Use double insulated tools appropriately rated for the work to be

performed.

AC Input Voltages

DANGER! This system operates from AC input voltage capable of producing fatal electrical shock.

Page 64

Vertiv™ NetSure™ Control Unit (NCU) User Manual

DC Output and Battery Voltages

DANGER! Connecting the NCU power system to an existing power system for “Power Split” mode involves working on live

equipment carrying live loads. This system produces DC Power and may have a battery source connected to it. Although the

DC voltage is not hazardously high, the rectifiers and/or battery can deliver large amounts of current. Exercise extreme

caution not to inadvertently contact or have any tool inadvertently contact an output terminal or battery terminal or exposed

wire connected to an output terminal or battery terminal. NEVER allow a metal object, such as a tool, to contact more than

one termination or battery terminal at a time, or to simultaneously contact a termination or battery terminal and a grounded

object. Even a momentary short circuit can cause sparking, explosion, and injury. Remove watches, rings, or other jewelry

before connecting leads. Cover any live busbars with a canvas sheet to prevent short circuits caused by falling tools or parts.

Preparing the Existing and NCU Power Systems

• Install and turn-up the NCU power system as describe in the installation instructions furnished with the power system.

• Set the float voltage on both the existing and NCU power systems to the same level. Temperature compensation

functionality, if used, should be disabled on both power systems.

Paralleling the Systems

• Connect the Battery and Battery Return busbars of the NCU Power System to the main charge busbars (rectifier side of the

shunt) on the parallel power system. Size the cable for the largest current between systems.

Note 1:

The connections between the two power systems should be done with power cables appropriately sized to be

capable of carrying the maximum current that can circulate between the two power systems.

Note 2:

If the parallel power system incorporates a main plant shunt, the connections of the cables from the NCU power

system to the parallel power system shall be made on the main charge busbars (rectifier side of the shunt).

Note 3:

To compensate for voltage drop, it is recommended to connect the power system’s remote sense leads (if

available) to the same point of sensing as the parallel power system.

Note 4:

There shall be only one battery return reference (BRR) cable for the two power systems. If the cable is

appropriately sized on the parallel power system, keep it as the BRR for both power systems. If the cable is not

appropriately sized on the parallel power system, install a new BRR cable and connect it preferably to the NCU

power system since the parallel power system may eventually be phased out.

Note 5:

If battery disconnect units (BDUs) are used on the new or parallel power system, these shall be wired in such a way

as to be all triggered simultaneously in order to prevent any overloading of these.

Note 6:

For the size and number of bridge cables between the two power systems, take into consideration the voltage

drop, the available connecting points in each system, as well as the fact that these cables are unfused and shall

therefore be run on a dedicated cable rack. “C” or “H” taps may be used to make full use of available connecting

points.

Note 7:

The legacy system retains the function of its controller and the percent of load on each plant is controlled by the

NCU. Alarms may be sent individually from each plant, or combined using an NCU Interface Board and the

programmable relays resident in the controller.

Note 8:

Add a label on both power systems to indicate that these are operating in the Power Split Mode with each other.

• Optional Function Connections: The following signals from the existing system must be connected to digital inputs of the

NCU system interface board for these functions to be active: Equalize Charge in Progress, Battery Test in Progress, Load LVD Active, and Battery LVD Active. Otherwise disable these functions.

Page 65

Vertiv™ NetSure™ Control Unit (NCU) User Manual

Programming the NCU Power Split Feature

After an NCU power system has been connected to an existing power system and both systems set for the same float voltage, you will have to configure the Power Split parameters in the NCU.

Procedure

1. In the Web Interface menus, set the Power Split mode to enabled. Navigate to Settings Menu / System / Power System /

PowerSplit Mode. Set this parameter to “enabled”.

2. Reboot the NCU by pressing ESC and ENT at the same time.

3. Navigate to Settings Menu / System / Power System.

4. Set the “Power Split Current Limit Value” to a value that will force the NCU system’s rectifiers to operate in current limiting

mode.

NOTE!

The Power Split Current Limit Value must be set lower than the total distribution current from the two plants. The

default value is 60% of the NCU power system’s rectifier capacity.

5. Set the “Delta Voltage”. This voltage is by default set to 0.5 V but can be readjusted.

• If the distribution current is lower than 50% of the total capacity of the NCU power system, the “Delta Voltage” can be

adjusted to a lower level than 0.5 V to get a system voltage that is closer to the desired float charging voltage.

• If the voltage drop between the existing system and the NCU system is expected to be >0.5 V, the “Delta Voltage” can be

adjusted to a higher level than 0.5 V to get a correct split function.

• Temperature controlled battery charging cannot be set in the NCU power system in power split mode. If this function is

implemented in the existing power system, a limited function within a temperature range of approximately ±15 °C will be achieved if the Delta Voltage is set to a higher level, maximum 2.00 V.

• If the “Delta Voltage” 0.5 V is considered to be too high, the split function can be tested at various modes of operation to

find a lower setting.

Optional Function Setup

Equalize Charge Setup

If the equalize charge function is to be used, equalize charge must be implemented in the existing power system and an equalizing signal from its control unit must be connected to the NCU.

1. In the Web Interface menus, navigate to Settings Menu / Battery / Equalize Charge Voltage. Set the “Equalize Charge

Voltage” to the same value as the equalize voltage of the existing power system.

2. Using the Web Interface menus (see “Power Split Tab” on page 215), select the NCU digital input connected to the existing

systems equalize control circuit.

NOTE!

Equalize charging is controlled by the existing power system via an incoming digital signal. The system will remain at

the set equalize charge voltage level as long as this signal is active.

Battery Test Setup

If the battery test function is to be used, battery test must be implemented in the existing power system and a test signal from its control unit must be connected to the NCU.

1. In the Web Interface menus, navigate to Settings Menu / Battery Test.

2. Set the “End Test Voltage” to the same value as the end voltage of the existing power system.

Page 66

Vertiv™ NetSure™ Control Unit (NCU) User Manual

3. Set the “Test Voltage Level” to the same value as the test voltage of the existing power system.

4. Using the Web Interface menus (see “Power Split Tab” on page 215), select the NCU digital input connected to the existing

systems battery test control circuit.

NOTE!

Other settings in this menu regarding “Battery Test” are inactive.

NOTE!

Battery test is controlled by the existing power system via an incoming digital signal. The system will remain at

battery test as long as this signal is active.

Low Voltage Disconnect Setup

If low voltage disconnect functions are to be used, they must be implemented in the existing power system and signals from its control unit must be connected to the NCU.

1. Using the Web Interface menus (see “Power Split Tab” on page 215), select the NCU digital inputs connected to the low

voltage disconnect control circuits.

Temperature Compensated Battery Charge

There is no possibility to activate the “Temperature Compensated Battery Charge” function when the NCU power system is configured for “Power Split” mode.

However, the possibility to change the “Delta Voltage” enables the NCU power system to follow the existing power system that has the functionality to a certain limit.

Example: The “Delta Voltage” in the NCU power system is set to 1.0V. The existing power system is set to compensate 3.0 mV/cell/°C. This means that the NCU power system can follow the temperature compensation of the existing; power system in the range of ±14 °C from the set normal battery temperature (3.0 mV x 24 cells x 14 °C = 1.008 V).

Verifying the Operation of the Power Split Feature

After programming the “Power Split” feature, verify its operation as follows.

1. In a Power Split application where the NCU power system is taking the entire load and the rectifiers in the existing power

system are all in the standby mode, use an external dry load bank of sufficient capacity to increase the load on the NCU power system over the “POWER SPLIT CURRENT LIMIT” value.

a) Verify that the NCU power system limits the total output of its rectifiers to the current equivalent to this programmed

percentage.

b) Verify that the NCU power system lowers its output voltage by the value of the programmed “DELTA VOLTAGE”.

c) Verify that the rectifiers in the existing power system take the additional load as the load increases pass the “POWER

SPLIT CURRENT LIMIT” value.

d) Further increase the load in order to exceed the total capacity of the rectifiers in the existing power system (or shut

down some of the rectifiers in the existing power system if the capacity of the external dry load bank is not sufficient). Verify that the NCU power system starts taking the additional load as soon as the total capacity of the rectifiers in the existing power system is exceeded.

2. In a Power Split application where the NCU power system is taking only part of the load (operating continuously at the

current level equivalent to the programmed “POWER SPLIT CURRENT LIMIT” percentage) and the rectifiers in the existing power system are taking the rest of the load, use an external dry load bank of sufficient capacity to increase the load in order

Page 67

Vertiv™ NetSure™ Control Unit (NCU) User Manual

to exceed the total capacity of the rectifiers in the existing power system (or shut down some of the rectifiers in the existing power system if the capacity of the external dry load bank is not sufficient).

a) Verify that the NCU power system starts taking the additional load as soon as the total capacity of the rectifiers in the

existing power system is exceeded.

2.12.2 NCU TL1 Feature

The NCU can send and receive TL1 messages and responses between itself and a customer client application. This includes autonomous messages sent by the NCU to notify the customer client application of alarms.

TL1 messages contain parameter values that indicate attributes and the state associated to signals. The NCU provides configuration parameters for all signals as needed to specify values of the TL1 attributes and states that are required in the TL1 messages. Configuration of TL1 attribute parameters is accessed through the WEB interface.

NCU TL1 Port

The NCU TL1 port transports TL1 messages between the NCU and a customer network operations center or client. Access through this interface is restricted to a User who logs on with the TL1 ‘ACTIVATE-USER’ request message.

The NCU TL1 port uses the telnet protocol (not SSH) over the NCU’s Ethernet connection and has requirements for specific operational settings. The NCU supports TL1 telnet operation over IPV4 and IPV6 networks. The NCU TL1 port is enabled and configured through the WEB interface.

Only one telnet connection through the NCU TL1 port is allowed at any time. The telnet connection is disabled when the TL1 interface is not selected by the customer. The telnet connection is considered disabled when all telnet ports indicate closed during a network scan of the Ethernet connection.

NCU TL1 Configuration

Webpages are provided in the NCU Web interface to configure signal parameters and settings that specify the signal’s TL1 attributes. See “Setting TL1 Parameters” on page 34.

2.13 Machine-to-Machine HTTP Interface

2.13.1 Description

This interface option must be specified when the system is ordered. It is enabled or disabled at the factory.

The Machine-to-Machine HTTP Interface option provides the ability for a machine to poll the NCU controller using a special URL for a pre-configured packet of information using HTTP-GET.

The URL requests are sent to the controller using the same port as HTTP. Note this function is not available over HTTPS. This interface assumes that the customer is on a secured network.

The interface can be used to retrieve data using third-party programs such as WGET and CURL.

The interface works with IPv4 and IPv6.

The interface is available from the controller when the controller uses a fixed IP address or a DHCP address.

The interface only supports one request/query at a time.

2.13.2 Using the Machine-to-Machine HTTP Interface Option

Refer to the following.

Request

The request consists of the scheme (http), authority (the IP address of the controller), the path (/data), and the query. The end of the query can be specified by # or by the end of the URL. Fragments are not supported.

Page 71

Vertiv™ NetSure™ Control Unit (NCU) User Manual

The URL address should include /data; otherwise, it is not processed by this feature. The URL address can contain /data? or /data/?.

The query (input parameters) in the request starts after the question mark (?).

There is an ampersand (&) between each field in the query.

The fields in the query can appear in any order.

The fields in the query are the starting time, the ending time, and 0 to 3 user keys. The starting time is assumed to be 4 hours before the current time if it is not specified. It can be up to 4 hours in the past. The ending time is assumed to be the current time if it is not specified. It can be up to 4 hours in the past.

The starting and ending time are specified in one of two ways. First, the time can be specified using “Unix timestamps”. The format is the number of seconds since Jan 01, 1970 UTC. For example, March 19, 2015 at 7:44UTC is 1426794290. The starting and ending time using the Unix timestamp format is specified using the field names stime and etime. The time is the local time on the controller.

The starting and ending time can also be specified using YYYY-MM-DD HH:MM:SS. Note that dashes (-) are used instead of slashes ‘/’. The starting and ending time using this format is specified using field names starttime and endtime. The time is the local time on the controller.

The URL can include 0, 1, 2, or 3 user keys. These keys are ASCII text (A-Z, a-z, 0-9, '-','.' '_', ‘~’), up to 16 characters in length. The keys are specified as ukey1, ukey2, and ukey3. The query can specify ukey3 without specifying ukey1 and ukey2.

The controller will respond to any abnormal request (two starting times, two ending times, ending time before starting time, unrecognized keywords, fields that are too long, etc.) with an error response.

Response

The response to the HTTP request is provided as a CSV table. The CSV table starts with a header line. There is one line (row) for each of the data records.

Error responses are also returned in CSV format.

Response Title

The header line contains the title for each field, enclosed in double quotes (“) and separated by commas. This is the format of the title line:

“DateTime”, “Epoch Time”, “Status”, “<title1>”, “<title2>”, “<titleN>”, “UserKey1”, ”UserKey2”, “UserKey3”

The <title> fields are the Full English Name of the samples in the table. There is one title for each signal which is sampled. The titles are enclosed in double quotes.

Response Data

Each row is one line. Each line is separated by a CR/LF.

There is always at least one row in the response.

The fields in the response are DateTime, EpochTime, Status, Signal1…SignalN, Userkey1, Userkey2, Userkey3.

Fields are separated with commas. There is no space after each comma.

The DateTime field is the sample time specified using YYYY-MM-DD HH:MM:SS. The time is the local time on the controller. It is not enclosed in quotes.

Page 72

Vertiv™ NetSure™ Control Unit (NCU) User Manual

The Epoch Time field is the sample time as the number of seconds since Jan 01, 1970 UTC. It is not enclosed in quotes.

The Status field is the return status of the request. The possible values for this field are listed below. These strings are enclosed in quotes.

“OK”

“No data in this time range.”

“The starting time and/or ending time is invalid.”

“The request is not understood.”

“Some requested signals are not available.”

The UserKey fields are the user keys, which were specified in the input request. The user keys are returned in every row in the response. They are always the last three columns in the response.

If a key is not present, then the data field in the output is empty. For example, if only ukey3 is specified, the output for the keys would be ,,<ukey3>. If no keys are specified, the output for the keys would be ,,.

The rows in the response always include the same number of columns (that is, the same number of comma’s). The number of columns (comma’s) is the same whether the status is OK and data is provided or the status is not OK and no data is provided. If the status is not OK, the response will be like:

Data Values

The data values in the response are selected using the Data History in the NCU. The signals that are returned in the response are selected in the configuration files and are cannot be changed directly by the user.

The display format specified in the signal’s configuration is used to format the value in the response.

The sampling signal can be a virtual (calculated) signal.

The following data types are supported: LONG, FLOAT, UNSIGNED LOG. ENUMs are not supported. Signals which are not in one of these formats are not included in the header line or the data. These signals are skipped.

The data in the response contains one row for each minute between the starting and ending time specified in the request.

The Storing Interval can be different than 60 seconds.

The data value in a row is the data at or before the one minute interval for that row.

Example: System Voltage is sampled every 5 minutes. The samples are:

54.2V at 12:10.10

54.4V at 12:15.10

The data is request from 12:14 to 12:17. The data in the response would be:

12:14.00… 54.2…

12:15.00… 54.2…

12:16.00… 54.4…

2.14 Resolving Alarms

Table 2-3 lists the alarms that are shown in the Web Interface Advance Settings Menu under the Alarms Tab. These are also the

possible alarms that display in the alarm screens on the local display and Web Interface. Table 2-3 also provides guidelines for fixing the condition that caused the alarm.

NOTE!

These instructions describe the complete functionality of the controller. Some functionality is dependent on

hardware connected to the controller. Some alarms listed may not display in your system or may be named differently. Refer

to the NCU Configuration Drawing (C-drawing) furnished with your system.

Refer also to the NCU Configuration Drawing (C-drawing) furnished with your system for the factory default “Alarm Severity Level” settings and “Alarm Relay” mapping to the available alarms.

Rectifier Lost Alarm Description: The rectifier lost alarm occurs if the NCU updates the inventory and finds that the number of rectifiers is different. Two conditions cause the NCU to update its inventory. The first condition is if the NCU reboots. Every time the NCU starts up it updates the inventory. The second condition is when a rectifier is installed in the system. This causes the NCU to update its inventory. When a rectifier is installed, the NCU re-inventories which clears any “Rect Comm Fail” alarms. The NCU then finds the inventory doesn’t match what it used to and a “Rectifier Lost” alarm is activated.
