User’s Manual

system description

(see figure 1)

■ a rectifier/charger module (A) converts

3-phase AC power from the normal AC source supply (1) into DC power for the normal inverter input and float charges or recharges the battery;

■ a battery unit (D) provides backup

power for the inverter in the event of a voltage drop or a normal AC source failure;

■ an inverter module (B) converts the DC

power supplied by the rectifier/charger module or the battery unit into 3-phase AC power for the load;

■ a static bypass module (C) ensures the

instantaneous transfer of the load to the bypass AC source input in the event of an inverter shutdown (initiated by the user or by a protective device) or a sudden overload;

■ a maintenance bypass isolates the UPS

for maintenance and transfers the load to bypass AC source input without interrupting the supply of power. The maintenance bypass is made up of three manual switches (Q3BP, Q4S and Q5N).

Note

■ the normal AC input and the bypass AC

input have different functions and, depending on the installation, may be protected differently upstream and/or come from different sources.

■ when increased power is required, sev-

eral Galaxy PW™ units may be connected in parallel (up to four). In this configuration, an "isolation" function is added for the UPS system as a whole for maintenance purposes, without interrupting the supply of power to the load.

The system may also include:

■ Isolation or auto transformers on both

input and output.

■ 2 CB or 3 CB maintenance bypass

■ different remote control, indication and

display systems.

operation in on-line mode

normal operation

Normal AC source power is available (see figure 5).

■ lights 1 , 4 and 5 shine green on

the control panel;

■ the power necessary for the load is pro-

vided by the normal AC source (1) through the rectifier/charger (A) and the inverter (B);

■ the rectifier/charger (A) also supplies

the power to float charge and recharge the battery if any. The rectifier/charger output voltage (DC) is regulated to supply:

❏ the float-charging or the recharging volt-

age for vented lead-acid or Ni/Cd batteries,

❏ a single charge voltage for sealed lead-

acid batteries. The voltages depend on the number of

battery cells and the battery manufacturer. Factory set, they may also be adjusted by after-sales support technicians. An electronic board continuously measures the battery temperature and automatically adjusts the voltages.

Note:

In parallel Galaxy PW™ systems, the power drawn by the load is equally shared between the different units.

Fig. 5

operation with the normal AC source down

See figure 6. In the event of a normal AC source failure or voltage outside specified tolerances of ±10% in amplitude (±15% optionally), the rectifier/charger (A) stops and the battery (D) supplies the necessary backup power to the load via the inverter (B). The battery, float-connected between the rectifier/charger and the inverter, discharges during this operating mode. Lights 2 , 4 and 5 shine green. The user is warned of battery operation by the slow beeping of the buzzer 6 (see figure 16) and the message "LOAD PROTECTED, BATTERY DISCHARGING", followed by the remaining backup time and the percent load. This information is also available via voltfree changeover contacts for remote control devices.

Fig. 6

battery time

The available battery time during a normal AC source outage depends on the:

■ rated capacity of the battery;

■ power consumed by the load;

■ temperature of the battery;

■ age of the battery.

The specified battery time corresponds to a minimum duration at full rated load. The actual backup time can therefore be greater if the system operates below its full rated load during the normal AC source outage. Operation on battery power can be extended beyond the specified time by reducing the load power consumption (by disconnecting non-critical loads). A "low battery" warning signal is sent via volt-free changeover contacts for remote control devices when the battery voltage reaches a level slightly above the minimum level. This signal warns the user of the imminent end of battery power. On the device itself, the buzzer beeps rapidly. The message "LOW-BATTERY SHUTDOWN WARNING" is displayed, followed by the remaining backup time and the percent load. Light 2 turns red and flashes. Battery power stops when the voltage supplied by the battery reaches the minimum threshold. This results in inverter shutdown and transfer of the load without interruption to the bypass AC source. Light

2 shines red (not flashing). The message "LOAD NOT PROTECTED, ONLINE MODE" is displayed and the buzzer sounds continuously. If the bypass AC source also fails, the load is no longer supplied. The inverter automatically shuts down when the time on battery power exceeds three times the specified backup time.

NOTE

The "low battery shutdown" warning signal can be sent with an adjustable time delay prior to the effective end of battery power.

operation with the normal AC source restored

See figure 7. When normal AC source power (1) is restored or its voltage returns to within specified tolerances, the system automatically returns to its normal operating mode described above (on the condition it did not reach the end of battery power). If the end of battery power was reached (with the resulting inverter shutdown), the rectifier/charger (A) restarts automatically, but the inverter (B) must be restarted manually. The rectifier/charger recharges the battery (D) which was discharged during the mains outage. During battery charging, light 2 flashes green. The message "BATTERY CHARGING" is displayed, together with the value of the recharging current and battery voltage.

The battery charge cycle takes place in two steps (see figure 8):

■ step 1: the battery is recharged at a

constant current limited to 0.1C10 (i.e. 1/10th of the battery capacity specified for a 10 hour discharge). The DC voltage increases with the battery charge until the charge level is reached;

■ step 2: the battery is recharged at con-

stant voltage equal to the charge level. The charging current gradually decreases until reaching a specified low value (floating current). For vented lead-acid batteries, the rectifier/charger supplies the charging voltage for 0 to 255 hours (parameter defined by the after-sales support department) and then the floating voltage. For sealed leadacid batteries, the charging and floating voltages are the same.

Battery charge cycle

Fig. 8

NOTE

If the normal AC source failure is shorter than 0 to 255 seconds (default value = 30 seconds) (parameter defined by after-sales support department), the charger automatically supplies the floating voltage given the low battery discharge.

inverter shutdown or overload

See figure 9 for devices or installations operating in on-line mode with a bypass AC source.

Fig. 9

single-UPS unit (on-line mode)

■ in the event of a UPS shutdown (initiat-

ed by the user or by an internal protective device), the load is automatically transferred to the bypass AC source. If transfer conditions are satisfied, transfer takes place instantly, without interruption to the load; Note: transfer conditions are not satisfied when bypass AC source characteristics are outside tolerances (voltage: ±10%; frequency as per personalization; phase sync with inverter ±3°);

■ in the event of a major transient over-

load (greater than 1.65 In), immediate transfer takes place as above, without interruption to the load. The return to the inverter is automatic when the overload disappears if the number of possible returns has not been reached (0 to 255, programmable by personalization). If this number has been reached, the load continues to be supplied by the bypass AC source. This operating mode allows start-up of load devices causing high inrush currents. This system requires satisfied transfer conditions.

If the conditions are not satisfied, the inverter will current limit to 165% of its rated current for 1 second before stopping;

■ in the event of a small but extended

overload (i.e. a continuous level of power exceeding the full rated load), the inverter will continue to supply power for a period depending on the magnitude of the overload (10 minutes for a 125% overload, 1 minute for a 150% overload). See the overload curve in figure 10;

■ in all three of the above cases, inverter

shutdown and supply of the load via the bypass AC source results in the following on the control panel:

❏ light 4 goes off, ❏ activation of the buzzer (continuous

beep),

❏ light 3 shines green, ❏ the message "LOAD NOT PROTECT-

ED, ON-LINE MODE" is displayed.

parallel UPSs without redundancy

The shutdown of one inverter results in overload on the other inverters in operation. Two cases may then arise:

■ if the overload on each remaining invert-

er is >

than 1.65 ln, the load is immediate-

ly transferred to the bypass AC source;

■ if the overload is less than 1.65 ln, the

remaining inverters support the overload (see curve in figure 14), and the load is transferred to the bypass AC source;

■ after this transfer:

❏ the light 4 goes off, ❏ the buzzer is activated and sounds con-

tinuously,

❏ the light 3 goes on and turns green, ❏ the message "LOAD NOT PROTECT-

ED, PARALLELON-LINE MODE" is displayed.

Fig. 10

parallel UPSs with redundancy

■ the shutdown of one UPS unit is of no

consequence for the load. The others each take up an equal amount of load power and the load continues to be supplied normally; Unit shutdown results in the following on the control panel:

❏ lights 4 and 5 go off, ❏ activation of the buzzer (continuous

beep),

❏ the message "LOAD NOT PROTECT-

ED, PARALLELON-LINE MODE" is displayed;

■ in the event of an overload, the system

only loses its redundancy as long as the overload is less than the total rated power of the functioning units. If the overload is greater, the operating mode is that previously described for systems without redundancy.

operation with an engine generator set

See figure 11 below. If a stand-by generator is included in the installation, it is generally started automatically in the event of a normal AC source failure and connected to the main low voltage switchboard. It is disconnected when normal AC source power is restored. With such a system, the required battery time may be reduced to the time necessary for starting and bringing on line the stand-by generator. The battery (D) sup- plies power to the inverter (B) during the transfers:

■ normal AC source to the generator;

■ generator to the normal AC source.

The transfer sequences described above (normal AC source ➜ battery, battery ➜ generator, generator ➜ battery, and battery ➜ normal AC source) are fully automatic. They in no way affect the load and require no manual operation by the user.

output voltage quality and continuity

The output voltage is stable in amplitude and frequency and is free of interruptions or transients outside specified tolerances, irrespective of normal AC source or load disturbances (outages, load step changes, etc.).

steady state voltage regulation

For stable or slowly varying load conditions, the inverter output voltage is regulated to within ±0.5% in amplitude. The frequency of the output voltage can theoretically be regulated to within 0.1% of the rated value, however the output frequency range may be intentionally extended to a maximum of ±2 Hz so that the inverter can remain synchronized with the bypass AC source and its inherent frequency fluctuations, thus enabling transfer of the load to the bypass line at any time.

When the bypass AC source frequency returns to within the specified tolerances, the inverter is gradually re-synchronized to the bypass line at a rate of 0.5 Hz to 2 Hz/s (as per the value personalized by the after-sales support department), thus avoiding exposing the load to sudden frequency variations.

transient voltage regulation

The inverter output voltage is not notably affected by instantaneous major variations in load characteristics. This is made possible by the PWM (Pulse Width Modulation) chopping technique and the microprocessor-based regulation system that instantly compensates for any variation. In particular, the inverter output voltage remains within +/- 2% of the rated voltage for load step changes of 0 to 100% or of 100 to 0%.

NOTE

The output frequency range can be personalized and if necessary modified on the customer site by a qualified MGE UPS SYSTEMS support technician from ±0.25 Hz to ±2 Hz in

0.25 HZ steps. When the bypass AC source voltage moves outside this frequency range, the inverter is desynchronised and operates in "free running" mode, with the output frequency regulated to a high level of accuracy by a quartz oscillator.

NOTE

To avoid load surges on the generator, the rectifier/charger is started with a 10 second maximum current consumption walk-in (lasting 3 to 10 seconds, depending on the percent load). To avoid overloading an undersized engine generator set, it is possible to set a maximum power level drawn by the normal AC input. Any additional power required is supplied by the battery. This modification can be made on site by an MGE UPS SYSTEMS field engineer.

general

The auto diagnostic system considers any system status other than normal as a problem. Before taking any action, note down the messages displayed on the control panel. Certain problems may prevent the control panel from functioning.

In this case, it is strongly recommended to call the MGE UPS SYSTEMS aftersales support department.

■ If the load is still correctly supplied with

power, it has probably been transferred to the bypass AC source (static bypass) and is therefore no longer protected (if the system is in on-line mode);

■ if the load is no longer supplied with

power, transfer it manually to the maintenance bypass (see section below).

maintenance bypass

This operation is possible only if the system includes a bypass AC source. It results in the load being directly supplied by the bypass AC source via maintenance bypass switch Q3BP, thus ensuring a higher level of security in the event of a malfunction. Switching procedures are explained on drawings next to each switch in the UPS cabinet and the external bypass unit. See section "maintenance configuration".

environment information

Terminals XR2, XR3, XR4 and XR5 on the "Media Contacts 11" board of each type of unit can be used to receive signals from the operating environment and to transmit signals concerning the operating status of the UPS (see figure 16 for the position of the board, item 12).

signal reception

The signals should be provided by voltfree contacts.

■ emergency off:

An NC contact causes shutdown of the inverter and the rectifier/charger, opening of the battery circuit breaker, blocking of the static bypass and activation of a relay contact on the "Media Contacts 11" board;

■ battery room ventilation fault:

An NO contact causes shutdown of the rectifier/charger;

■ battery circuit breaker QF1 closed:

An NO contact prevents inverter start-up if the circuit breaker is open;

■ battery temperature:

A PC-board, placed near the battery, supplies information on the battery temperature, thus enabling the rectifier/charger to regulate the battery voltage;

■ "auxiliary" signals:

Depending on the selected settings, these signals may be used to provoke:

❏ forced shutdown of the inverter (whatev-

er the status of the bypass AC source),

❏ protected shutdown of the inverter (load

transfer to the bypass AC source).

❏ limiting of the current drawn by the recti-

fier/charger (programmable value) when supplied by an engine generator set with an insufficient power rating. The additional power required by the inverter is supplied by the battery which discharges,

❏ limiting of the battery charge current

(programmable value) if the normal AC source is replaced by an engine generator set with an insufficient power rating.

signal transmission

■ an auxiliary 24 V power supply, isolat-

ed and backed up, is used to supply:

❏ the undervoltage release of the battery

circuit breaker(s) QF1,

❏ the board that measures the tempera-

ture in the battery room;

■ "low battery" warning signal (volt-free

changeover contact) indicating that battery time is about to run out. The warning threshold may be personalized;

■ "load on UPS" signal (volt-free

changeover contact) indicating that the load is supplied by the inverter. For a single-UPS unit, one volt-free changeover contact may be used to indicate that the load is supplied by the bypass AC source;

■ "load on battery power" signal (volt-

free changeover contact) indicating that the inverter is supplied by the battery in the following cases:

❏ normal AC source outage or voltage

drop,

❏ rectifier/charger shutdown, ❏ rectifier/charger current limiting.

This signal, which may be used to initiate process saving and shutdown procedures, is time-delayed 30 seconds to avoid unnecessary operations following microbreaks;

■ "maintenance position" signal (volt-

free changeover contact) indicating that:

❏ maintenance bypass switch Q3BP is

closed,

❏ bypass AC source input switch Q4S is

open,

❏ inverter output switch Q5N is open, ❏ battery circuit breaker QF1 is open;

■ signal to open battery circuit break-

er(s) QF1 in the event the "emergency off" button is pressed or to avoid an excessive battery discharge (lasting more than three times the rated backup time plus two hours);

■ repo contact (volt-free changeover con-

tact) used to trip switching devices in the event of an emergency shutdown.

■ "general alarm" information (volt-free

changeover contact) which includes:

❏ internal faults, ❏ information on temperatures outside tol-

erances in the battery room (optional),

❏ overload information (> In), ❏ static-switch ventilation and power-sup-

The battery capacity is the value mea-

sured by the UPS microprocessor. It is expressed in Ampere-hours. This value changes over time depending on the parameters of the battery itself and its environment. This measurement is used to check that the battery is capable of supplying the rated power in the event of a mains outage.

The backup time is the value calculated by the UPS microprocessor on the basis of measurements carried out on the battery. It is expressed in minutes. The calculation uses the percent load and the battery charge status at the time of the measurement.

The load level is the ratio between the power supplied by the UPS to the load at the time of the measurement and the rated output of the UPS. It is expressed as a percentage.

utilization via Teleservice

When the optional JBUS RS232/485 communications board is installed, the timestamped information can be sent to the Teleservice center. The center can remotely consult the same information and carry out the same modifications as the user locally on the display. Note that only the Teleservice centre can reset the counters for the statistical data.

■ UPS isolation

Proceed in the following order (see figure

20):

❏ shut down the inverter (press the "invert-

er OFF" button 8 for three seconds),

❏ close bypass switch Q3BP, ❏ open isolating switches Q5N, Q4S, QF1

and Q1. The UPS is powered down once the capacitors have discharged (a few minutes);

■ start-up

Following servicing, proceed in the following order (see figure 21):

❏ close switch Q1, then after approximate-

ly ten seconds, switches QF1, Q5N and Q4S,

❏ open bypass switch Q3BP, ❏ start the inverter (press the "inverter ON"

button 7 ).

CAUTION

■ work should be car-

ried out in accordance with applicable safety regulations;

■ to avoid interrupting

the load, the various switching operations must be carried out in the correct order. Operations are explained in diagrams placed next to the switches;

■ the system cabinet is

only partially powered down. The load is still supplied via the bypass AC source and switch Q3BP.

User’s Manual

battery maintenance

Consult the instructions supplied by the battery manufacturer. Below are a few general indications:

■ sealed lead-acid batteries: these bat-

teries require no maintenance, but check the terminals of each cell from time to time and clean if necessary;

■ vented lead-acid batteries:

❏ check the electrolyte level regularly and

add water if necessary,

❏ check the voltage of each cell to deter-

mine if it is necessary to equalize the battery,

❏ check the terminals of each cell and

clean if necessary.

visual check

■ Power down the system prior to any

maintenance operations. Note: in redundant parallel UPS systems the check may be carried out successively on each UPS unit without interrupting the load. In other configurations, the load must be supplied via the maintenance bypass (see "maintenance bypass" in the "Alarm" section);

■ clean the system regularly, particularly

the air filter inlet and outlet grills. Check that the air circulates freely in the cabinets. Use a vacuum cleaner if necessary;

■ check that nothing hinders the ventila-

tion at the top and at the back of the system.

functional check

■ Check that lights 1 , 2 and 3 on the

control panel are not red, to avoid an interruption in the supply of power to the load due to incorrect transfer conditions or a battery problem;

■ press the "inverter OFF" button and

check that the buzzer and control panel lights function correctly (see the section on operating modes in the introduction);

■ press the "inverter ON" button and

check again that the control panel lights function correctly;

■ run a transfer to battery test. With the

inverter on, open input circuit breaker Q1. The orange "battery" light on the control panel should light. After two minutes on battery power, close input circuit breaker Q1. The rectifier/charger should automatically restart and the orange "battery" light on the control panel should go off;

■ in parallel systems, run these tests on

each UPS unit.

CAUTION

Battery maintenance is undertaken with the system powered up. Operations must be carried out in accordance with applicable safety regulations by qualified personnel using insulated tools, gloves and safety goggles.

Batteries contain dangerous substances that will harm the environment if thrown away. If you change the batteries yourself, call on qualified organizations for battery recovery and recycling.

Maintenance

Galaxy PWTM100 to 225 kVA

Galvanic isolation and voltage matching transformers

The UPS can be equipped with an isolation or auto transformer on both the input and output to provide galvanic isolation or voltage step-up or step-down as required.

Maintenance bypass

Maintenance bypass option provides a direct bypass AC input source (mains 2) that can be used to supply the critical load while the UPS is being serviced.

electrical supervision

"Teleservice"

"Teleservice" is a contract offering continuous remote supervision and maintenance of UPS systems via a modem. Real-time communication is established with our "Teleservice" centre for communication of all alarms and events occurring in the installation.

GTC board

This electronic board provides user access to the J-Bus communications protocol. Using the data and address tables provided, the user can customize his installation.

GTC + software

The user has access to the J-Bus protocol and, in addition, the associated software acquires system parameters (measurements, status conditions) and transforms them into diagrams, alarm messages and tables. With the click of a mouse, the user can locally or remotely supervise the UPS system (comprising one or many UPS units).

management of computer networks

Integrated SNMP agent

This electronic board, installed in the UPS system, enables direct connection to all Ethernet networks using TCP/IP. The UPSs may then be supervised via the computer network. Furthermore, they can be used to close system files without having to add an external SNMP agent. This board is fully compatible with "Solution PacTM" software.

The RJ45 connector of the communications option delivers information using the SNMP protocol. The sticker located on the board indicates the UPS MAC address.

■ your MAC address is written in the fol-

lowing way : 0080C8 ZZ XX YY ;

■ your default IP address is 168.8.xx.yy

(xx and yy are decimal values of XX and YY).

For example, MAC address 00 80 C8 AB AA 01 is related to IP address

168.8.170.1.

Please refer to the "userman.doc" user manual contained in the directory "emb/galaxy/snmp/release3.xx" of the Solution-Pac CD-ROM in order to discov-

er the management capabilities of your SNMP Galaxy PW™ UPS. Please contact your sales representative for more detailed information.

Two-channel network board

This electronic board comprises two ports, each of which may be user set, either for the U-Talk protocol or as a relay contact. U-Talk is the protocol required to establish contact with the communications software. Relay contacts may be used for specific network applications (IBM AS400, Novell, etc.).
