In Xtra-VFI Mode, the UPS system adapts the power capacity according to the partial AC load by put-ting the unused UPS module in stand-by mode. The remaining UPS modules are operating in double conversion mode. The UPS system autonomously decides which UPS module goes into stand-by mode. The system shall rotate/swap the UPS modules between the double conversion mode and the stand-by mode to extend the operating life and equalize aging.The status of the UPS Module in Xtra-VFI Mode is displayed as follow:

5.1.5.6 User



By touching the Xtra VFI icon, the user acquires access to the Xtra-VFI settings. The Xtra VFI mode al-lows turning into standby mode of a certain number of UPS modules according to the required power capacity by the AC load.

The following conditions shall be considered before the Xtra-VFI function is activated:

• The UPS system is operating in double conversion mode.• The UPS output switch (Q2) is closed• The total number of UPS Modules inserted into the UPS system is equal to the total number of UPS

Modules in the system• There is no active alarm within the system • The battery test is not active

Xtra VFI Statuses

Xtra VFI can assume the statuses listed and described in the following table. The current status is shown on the display on the screen Xtra VFI measurements (see figure 11.3.2-2 in the chapter 11.3.2).

MESSAGE MEANING

“Disabled” Xtra VFI is disabled (factory default).

“Active” Xtra VFI is active.

“Rotation” Module rotation in progress.

"To standby" One or more modules are changing status from double-conver-sion into standby mode.

“Sysmod invalid” The “Total UPS Number” parameter has not been inserted.

“Sysmod wrong” The “Total UPS Number” parameter does not correspond with the quantity of the UPS modules in the system.

“General alarm” Any alarm on any of the modules generates the general alarm.

"Q2 open” One or more UPS output switch(es) are OPEN.

“Battery test" One or more modules are performing the battery test

Standby modeWhen the UPS module goes into the standby mode it turns off the inverter, in order to reduce power consumption. The control logic as well as the rectifier and battery charger remains active. The UPS module in Stand-by mode needs 40-50 ms to turn on the inverter and operate in double-conversion mode if the system requires it.

Module rotationModule rotation allows to keep the aging of the modules more or less balanced over time. The module rotation will take place automatically, once a week, exactly 24*7 hours after the last time Xtra VFI has been started (enabled) and it works in the following way: there is a form of intelligence that determines how many UPS modules it is worth swapping. Once this is defined, the system turns ON (change status from Standby mode to double conversion mode) the defined quantity of UPS modules first; then, once those are in a steady state, it puts the same quantity of the UPS modules which were previously in dou-ble conversion in the standby mode.

ONLY PEOPLE WHICH HAVE BEEN TRAINED BY SERVICE TECHNICIANS OF THE MANUFACTURER OR HIS CERTIFIED SERVICE PARTNERS ARE ALLOWED TO ACTIVE OR DISABLE THE XTRA-VFI MODE IN THE UPS SYSTEM.

—7 Maintenance & troubleshooting

THE OPERATIONS DESCRIBED IN THIS CHAPTER MUST BE PERFORMED BY A CERTIFIED SERVICE ENGINEER OF THE MANUFACTURER OR BY AN AGENT CERTIFIED BY THE MANUFACTURER

7.1.1 User responsibilitiesThe user is not allowed to carry out maintenance on the UPS, we recommend that you contact local certified service engineers.

7.1.2 Preventive maintenanceThe UPS system needs regular and constant maintenance (preventive inspections) at least once a year, even during the warranty period.

Please refer to your authorized service partner for the recommended maintenance plan (including the specific scheduled replacement of fans and power capacitors). Performing regular and pre-ventive maintenance not only keeps perfor-mance stable and extends the life of the equip-ment, but also decreases the risk of failure. In case these activities are not performed correct functioning of the equipment may be affected.

Maintenance inspections are essential to ensure a correct functionality and reliability of the UPS system.

During maintenance the field service engineer may carry out some or all of following checks:• Status and function check of UPS and batteries• UPS and batteries visual inspection (dust, me-

chanical damages, ...)• Visual inspection of screws and cable connec-

tions• Check of air ventilation and room temperature• Check the operation and function (commuta-

tions, remote monitoring and Signaling)• Current, voltage and frequency measurements• Measuring and registration of current load con-

ditions

• Checking of load sharing (only in parallel sys-tems)

• Battery voltage check• Battery discharge test• Check transfer of the load from UPS to mains

operation via static bypass• Unit cleaning• Preventive replacement of fans and capacitors

7.1.3 Deep battery testThe battery test takes approx. 3 minutes and should be performed only if:• There are no alarm conditions • The battery is fully charged • Mains is present.

The battery testing can be carried out inde-pendently of the operation mode (OFF-LINE or ON-LINE) and whether or not the load is con-nected. The battery test procedure can be per-formed from the UPS HMI, in the “User” setup menu or in the “Set-up User” menu of the Service Control Panel. The battery test can be planned and executed periodically once a month

7.1.4 Battery maintenance, disposal and re-cycling

BATTERY MAINTENANCE SHOULD BE CARRIED OUT BY A CERTIFIED SERVICE PARTNER.

TO ENSURE OPTIMUM OPERATION OF THE UPS SYSTEM AND CONTINUOUS AND EFFICIENT PROTECTION OF THE CONNECTED LOAD WE RECOMMEND CHECKING OF THE BATTERIES EVERY 12 MONTHS.

BATTERIES CONTAIN DANGEROUS SUBSTANCES THAT WILL HARM THE ENVIRONMENT IF DISPOSED OF. IF YOU CHANGE THE BATTERIES YOURSELF, CALL QUALIFIED ORGANIZATIONS FOR BATTERY DISPOSAL AND RECYCLING.

THE UPS SYSTEM, THE BATTERY CABINET AND THE BATTERIES ARE HEAVY AND MAY TIP DURING TRANSPORTATION CAUSING SERIOUS INJURY IF UNPACKING INSTRUCTIONS ARE NOT CLOSELY FOLLOWED.

8.3.2 BatteriesThe battery life depends very much on the ambient temperature. It is therefore important to follow the storage instructions/recommendations of the battery manufacturer. For long-term storage make sure that the battery is fully recharged every 6 months. Before and after storing, charge the battery.

Always store the batteries in a dry, clean, cool environment in their original packaging. If the packing container is removed protect the batteries from dust and humidity.

WARNING

SEALED BATTERIES MUST NEVER BE STORED IN A DISCHARGED OR PARTIALLY DISCHARGED STATE.EXTREME TEMPERATURE, UNDER- AND OVERCHARGE AND OVER DISCHARGE WILL DESTROY BATTERIES

9.2.1 Battery cabinet location

In most cases the battery cabinet is positioned alongside the UPS cabinet (unless the UPS cabi-net requires side access) and takes advantage of the seam clearances. The minimum needed clear-ances of the battery cabinet depend on the de-sign of the cabinet (especially the openings). As VRLA batteries need natural ventilation, it is al-ways recommended to keep a certain clearance from the openings. How much that clearance needs to be highly depends on installation, good practice is to maintain a minimum of 100mm clearance at the walls with opening.

—13 Adding/replacing a UPS module

— 13.1 Single module system

NOTE


THE OPERATIONS DESCRIBED IN THIS CHAPTER MUST BE PERFORMED BY A SERVICE ENGINEER OF THE MANUFACTURER OR BY AN AGENT CERTIFIED BY THE MANUFACTURER

There are two reasons for which removal or reinsertion of a module is required:• Module maintenance• Module failure

The procedures described on this chapter are almost the same in both cases. Follow carefully the pro-cedures to avoid any possible issue with the critical load.

In case the single operating module experiences a fault, the load will automatically be transferred to STATIC BYPASS mode and it will continue to be supplied by the mains power supply.

In this situation, the load must first be trans-ferred to maintenance bypass (Q1, if present) or to external maintenance bypass before the mod-ule can be removed.

13.1.1 Remove the module from the frame

Skip step 1 in case of module maintenance.1. Reset the alarm on the faulty module. The

acoustic signal will stop. If the alarm condition persists (Relative

ALARM LED indicator always RED) the module must be probably removed for analysis.

2. If the module already operates in STATIC BY-PASS mode, the maintenance bypass switch Q1 (if present) can be immediately turned to the ON position (closed).

If the maintenance bypass switch Q1 is not present, turn to the ON position (closed) the external maintenance bypass switch instead.

3. If the module still operates in INVERTER MODE, transfer first the load to STATIC BY- PASS mode.

Perform this operation by means of the module display or, if present, the general TFT display installed on the frame.

Under the “COMMAND” menu select “LOAD TO BYPASS” (If required, enter the password if the command is performed through the TFT display).

4. Turn to the ON position (closed) the mainte-nance bypass switch Q1 (if present) or turn to the ON position (closed) the external output bypass switch instead.

The message “MAN BYP CLOSED” will appear in the event log of the module as soon as the maintenance bypass switch Q1 is closed.

The load is now directly supplied by Mains and it is not protected.

— 13.2 Redundant multi-module system

If in a redundant parallel system an UPS module is faulty, the load will continue to be protected by the remaining modules operating in an on-line-mode (INVERTER mode) and the faulty module can be replaced without having to transfer the

load to bypass!The same situation exist in the case of module maintenance, where the remaining modules oper-ating on-line-mode (INVERTER mode) will con-tinue to protect the load.


Skip step 1 and 2 in case of module maintenance.

1. Identify the faulty module with the alarm condition active.

2. Reset the alarm by pressing the BACK button on the module panel control.

The acoustic signal will stop. If the alarm conditions persists (relative ALARM LED in-dicator always RED) the module must be probably removed for analysis.

3. Load OFF the faulty module by means of the ON/OFF button present on its control panel (Confirm with “ENTER” when required). Perform the same operation in case of mod-ule maintenance operation.

Do not forget to always check that the re-maining modules on the parallel system can still supply the load! (Verify load measures on the operating modules).

4. Turn to OFF position (open) the relative mod-ule battery breakers present on the frames.

5. Unscrew the two screws on the front side of the module that fix it to the UPS-frame.

6. Pull the module only partly horizontally by means of the 2 black handles until the rear connectors are disconnected.

7. Wait approx. 5 minutes before completely re-moving the module from the frame to be sure the AC and DC capacitors installed in it are completely discharged.

8. To extract the module completely, press down the top left yellow tab (as shown in the figure) and then extract the UPS module by pulling it out horizontally.

NOTE


9. Insert new the UPS module or close the opening (UPS module compartment) with ap-propriate protection cover immediately (Fix the cover with two screws).

10. If the problem on the faulty module has caused a change in the complete parallel sys-tem operation mode (from INVERTER to BY- PASS mode or vice-versa) restore now the original situation. Transfer the load from STATIC BYPASS to IN-VERTER mode or vice-versa by means of one module display or the general TFT display in-stalled on the frame. Under the “COMMAND” menu select “LOAD TO BYPASS” (If required, enter the password in case the command is performed through the TFT display).

11. Verify that all remaining modules are operat-ing on the correct original mode.

— 13.3 Capacity multi-module system

If in the capacity parallel system a UPS module ex-periences a fault and there is not enough capacity left to protect the load by the remaining operat-ing UPS modules, the load will automatically be transferred to STATIC BYPASS and will continue to be supplied by the mains power supply.

The same situation exists when a module requires maintenance and the remaining ones still operat-ing in parallel cannot provide enough capacity to protect the load. In this case the load must be previously transferred manually to STATIC BY-PASS mode to be supplied by the mains power supply.


Skip step 1 and 2 in case of module maintenance.

1. Identify the faulty module with the alarm condition active.

2. Reset the alarm by pressing the BACK button on the module panel control.

The acoustic signal will stop. If the alarm con-ditions persist (relative ALARM LED indicator always RED) the module must be probably re-moved for analysis.

3. Verify that the parallel system is already op-erating in BYPASS mode and the load is sup-plied by the mains power.

If not, transfer the load from INVERTER to STATIC BYPASS mode by means of one module display or the general TFT display installed on the frame.

— 14.3 Xtra VFI

14.3.1 Setup mode

In order to set up the Xtra VFI feature correctly, these two parameters must be known:• Highest Load Step (HLS)• Redundancy level

These parameters are explained in the next two sub-chapters.

Highest Load Step

The HLS parameter has to be inserted by your certified service personnel and can be adjusted at any time; access to the service-menu is required (service menu › settings › Xtra VFI). HLS should correspond to the highest load increase (load step) to be expected within the system in less than 50 ms, which the UPS system has to handle without any compromise.This parameter can be inserted as percentage of the total system capacity or as absolute value in kW or both (when both parameters are inserted, the system considers the worst case).

The factory default values for HLS are:

HLS in kW 0 kWHLS in % 0%

The factory default values for HLS are:

HLS in kW 0 – 3’000 kW (integer, positive)HLS in % 0 – 100 % (integer, positive)

In case the inserted value exceeds the physical possibilities of the system (e.g. HLS=1’200kW when the system capability is only 1’000kW) the UPS system applies the maximum possible value (in our example it would be 1’000kW).

Redundancy level

The redundancy level parameter has to be in-serted by the user (service menu › settings › Xtra VFI) and can be adjusted at any time. The redun-dancy level should correspond to the desired re-dundancy that the system should have. Typically, the redundancy level parameter=1, which means one additional module.

The factory default values redundancy level is

Redundancy level 0 modules

The possible values to insert are

Redundancy level 0 – 30 modules (integer, positive)

In case the inserted value exceeds the physical possibilities of the system (e.g. Redundancy level =24 when the system capability is only 20 mod-ules) the UPS system applies the maximum possi-ble value (in our example it would be 20 modules).

Start Xtra VFI

Once the two above parameters have been defined and set, Xtra VFI can be started simply by enabling it on the graphical display by your certified service personnel, access to the service-menu is required (service menu › settings › Xtra VFI) and can be disabled at any time.

The operating system you are using must support the SNMP protocol.

We offer our software with SNMP functionality for Novell, OS/2, all Windows running on INTEL and ALPHA, DEC VMS, Apple.Two types of SNMP interfaces with identical func-tionality are available: an external SNMP-Adapter (Box) and an internal SNMP-Card. Both can man-age a parallel system (N modules) and return ei-ther global values - which are consistent for the whole parallel system - or specific values from the single modules.

External SNMP-Adapter

Internal SNMP-Card—15.1-2

—15.1-2: SNMP

The adapter may be configured via Telnet, HTTP (Web-Browser) or serial connection (Terminal). For normal operation at least one network con-nection (Ethernet) is required.

The SNMP adapter can be used, utilizing the RC-CMD send function, for an automatic network wide shut down or just for informing connected users. The shutdown procedure can be initiated on a low residual battery autonomy time (down-time) or by a countdown timer which is started at the beginning of the alarm. A shut down is there-fore possible without extra input from the opera-tor, and is fully software controlled.

The small (125x70 mm) External SNMP adapter comes with following interfaces:

1. RJ-45 connector for 10/100 Base-T (auto-switchable)

2. Serial Port for configuration (COM2) or optional ModBus interface.

3. Error/Link LED for UPS status4. Aux Port5. DIP Switch6. Serial Port to the UPS (COM1)7. DC Supply (9 VDC or 9-36 VDC supply,

depending on model)

The Internal SNMP-Card can be inserted into an appropriate extension slot of the PMC. This adapter communicates via the serial port of the UPS and makes a direct multiple server shut down possible without additional SNMP management software.

For detailed information please refer to the Soft-ware Manual provided with the PMC-Software CD ROM. RCCMD - Remote Console Command mod-ule for a multi-server shutdown. This standalone software module is designed to receive and exe-cute a command issued by a remote device. Thanks to RCCMD it is possible to execute a shut-down in a heterogeneous multi-platform net-work. The new release RCCMD2 is an application available for all Operating Systems, analogous to PMC-Software. Our SNMP Interfaces are compati-ble with RCCMD.

— 15.3 Battery temperature sensor

15.3.1 Functions

The option Battery Temperature Sensor, if correctly installed has the following two functions:

1. Allows the battery temperature to be shown in the menu of the LCD display (see chapter 5.2.2.3)2. Allows the battery charger to automatically and continuously compensate the charging voltage ac-

cording to the values: 2.30 V/cell @15°C Linearly to... 2.23 V/cell @35°C.

15.3.2 Battery temperature probe installation

The sensor comes with a 1.8m cable, if a longer cable is needed, it can be extended up to 15m. First de-fine the position of the sensor, it is best to put it where the temperature gets higher (typically it’s on the top of a battery cabinet or UPS internal battery (or even battery room).Then, thread the wire by fixing it along the way and connect the two ends of the cable by plugging them into the customer interface (see chapter 5.3) on the pin X3/13 and X3/14. The polarity does not matter (not important which end is connected at X3/13 and which at X3/14).
