Frequently asked questions
What is the output of the VSS+ DC in normal operation?
The average consumption required to keep the VSS+ DC in operation is less than 300 Watts (less than 0.2% of 160 kW). This performance level is the product of the technology employed: operation in vacuum, magnetic bearings for operation with levitation, synchronous motor, cooling system which is activated when the temperature is high.
What is the permissible ambient temperature range?
Starting: 0 to 50 °C
Operating: - 20 to 50 °C
Storage: - 20 to 80 °C
How long is needed to recharge the VSS+ DC?
As a general rule, it takes approximately 2 minutes. The time depends on the power of the UPS charger. For certain applications, it is possible to obtain a back-up time of 20 seconds by adapting the UPS charger. If a fault occurs on the electrical grid during the recharging phase, the VSS+ DC will provide power with the energy available.
What are the standard specifications of the VSS+ DC?
The VSS+ DC systems have many advantages over traditional flywheel systems:
• High reliability
• Low maintenance
• 20-year service life
• Easy to install
• Takes up little room
• Improved output >99.8%
• Controlled by microprocessor
• Self diagnostic
• Command control via LCD display
• Rapid recharging time (20 seconds to 2 minutes)
• Cabinet with wheels
• Easy to install
• No particular engineering requirements
• Compatible with DELPHYS MP and MX UPS
• Possibility of setting up units in parallel without any adaptation
• Maintenance via front panel
What is the difference between a low-speed and high-speed flywheel?
Flywheels can be placed into two categories depending on the speed of rotation.
Low-speed systems generally comprise steel flywheels which rotate at less than 10,000 revolutions/minute. The energy stored by the rotating weight is proportional to the speed squared; if the speed is increased, the rotating weight can be reduced.
The advantage of low-speed systems is that they have a relatively simple design. However, the power they produce is low in relation to their mass and they have numerous mechanical bearings which create friction which in turn consumes energy and reduces output.
The high-speed VSS+ DC systems employ a composite flywheel with magnetic levitation. The speed of rotation of the flywheel is greater than 50,000 revolutions/minute. The advantage is that a sizeable power is obtained for a low mass, it is very compact, there is no friction, output is higher and there is a reduced need for maintenance.
Can the VSS+ DC be controlled remotely?
The VSS+ DC can be controlled remotely via the local network or via a modem connected to a telephone line.
Do the VSS+ DC systems use mechanical bearings?
One of the main advantages of the VSS+ DC compared to traditional flywheels is that the bearings (5 of them) are levitated. 2 radial bearings are used on the magnetic X axis, 2 on the Y axis, 1 on the Z axis in order to keep the rotary assembly levitated. There is no friction and therefore no losses and no requirement for bearings to be maintained.
Why should the VSS+ DC be used instead of batteries?
Compared to batteries, the VSS+ DC is favourable in the following ways: greater reliability, a longer life, reduced need for maintenance, insensitivity to ambient temperature, consistent performance with frequent use (cycles), rapid back-up time, easy to install, an attractive price giving a quick return on investment.
To which standards do the VSS+ DC systems comply?
CE marking Low voltage directive: CEE 73/23 and CEE 93/68
Machine directives CEE 98/037 and CEE 98/79
Machine safety, section 1, general specifications CEI/EN 60204-1
Electromagnetic compatibility: CEE 89/336, CEE 92/31 and CEE 93/68
How do you set up the VSS+ DC?
The design of the equipment is based on "plug and play" with only one connection needed to the UPS direct current bus. The cabinet can be moved on a pallet truck. The equipment has wheels so it can be moved around.
What about the safety of the equipment?
The VSS+ DC was originally developed in line with the numerous constraints imposed on the design of passenger vehicles. Numerous tests were carried out in the development stages to ensure that there would be no danger in the event of a major incident. The results of the tests were confirmed by UL and TUV laboratories.
What about the noise level for the VSS DC?
The system is very quiet: the noise level is less than 45 dBA at 1 metre in normal operation.
What is the VSS+ DC?
The VSS+ DC is an innovative system for storing energy manufactured by PENTADYNE. It operates with the DELPHYS MP or MX UPS and has been designed as an alternative to using batteries, for the purposes of back-up.
Is an alternative voltage source required?
Certain internal functions require an alternative source of 120 or 230 V at 50 or 60 Hz. The UPS output provides this voltage.
What is the service life of the VSS+ DC?
The VSS+ DC systems have been designed to last 10 years.
What are the dimensions of the VSS+ DC?
Width: 630 mm - Depth: 830 mm - Height: 1800 mm The dimensions are such that the equipment can be moved through a standard-sized door frame
It weighs 590 kg,
This minimises the load on the ground.
What is the nominal speed of the VSS+ DC flywheels?
The rotating assembly rotates at more than 500,000 revolutions/minute.
Does the VSS+ DC system use a pump to maintain the vacuum?
One of the major advantages of the VSS+ DC over other flywheels is that no vacuum pumps are required.
The system that creates the vacuum, in the space where the inertia wheel rotates, is built into the rotary assembly; it does not require maintenance or replacement.
It maintains a constant vacuum, almost like in space, which is a million times lower than atmospheric pressure, removing nearly all aerodynamic resistance which in turn reduces losses. This systems removes the necessity for an external vacuum pump which consumes electrical energy, requires regular maintenance and which might need to be replaced.
What is a Flywheel?
A flywheel is a "mechanical battery" which stores electrical energy using a rotating weight. The energy can be permanently tapped into. Just as a chemical battery is kept floating, a flywheel is kept in rotation by its connection with a direct current bus from the output of a UPS charger.
How do you know if the VSS+ DC has been fully charged?
Unlike batteries, it is easy to find out the charge status of the VSS+ DC. Available energy is proportional to the speed squared. Thus, when the flywheel is at full speed, the entire amount of energy is available. The information can be viewed on the LCD display.
What is the back-up time for the VSS+ DC?
The VSS+ DC systems have been designed to obtain 160 kW of power in the space of 12.5 seconds. With a load of 180 kW, the back-up time will be 5 seconds, for 145 kW: 15 seconds, 120 kW: 20 seconds, 60 kW: 40 seconds. To increase the power and reduce the back-up time, several VSS+ DC systems can be set up in parallel.
What are the key technologies used in the VSS+ DC?
The VSS+ DC systems use cutting-edge technologies:
A high-speed carbon fibre flywheel
A magnetically-levitated rotating assembly
A built-in vacuum device
A synchronous generator motor
How many VSS+ DC systems can be set up in parallel?
During tests, 8 VSS+ DC systems were set up to operate in parallel on the direct current bus of a unitary UPS. However, it is possible to increase this number according to power needs and redundancy.
Where would the VSS+ DC be used?
The VSS+ DC is designed for high-quality energy consumers requiring a high level of reliability: service, industrial, medical, telecommunication sectors.
Is there a maximum ambient temperature for the correct operation of a UPS ?
The ideal ambient operating temperature for a UPS is 20°C. Nevertheless, the UPS and its components can operate satisfactorily within a range of 0°-35°C, excluding the battery. Using sealed lead-acid batteries requires a maximum local temperature of 25°C in order to maintain optimum reliability.
Do I need a communication software ?
The UPS supplies power back-up in cases of electrical network failure. However, this back-up may not be enough to cover longer cut-offs and you may not be there yourself to correctly close-down your files and your IT system. LOCAL VIEW communication software is designed to automatically carry out all the necessary operations to closedown your system before the end of battery back up. LOCAL VIEW also offers remote communication with your UPS systems:
• Status monitoring
• Control programming
• Statistics print-out for the quality of supplied power
• Remote warning via fax, Email, MS-Exchange or pager.
Are there any norms or standards concerning the choice of a UPS ?
There are numerous national (NF) and international (IEC) standards for UPS, but those standards covering safety (NF …), electromagnetic compatibility (IEC …) and quality (ISO) are all given priority. SOCOMEC SICON UPS satisfy all these standards and are also ISO 9001 certified.
Is it necessary to protect a printer with a UPS ?
No, unless it's an industrial-style printer.
What does a UPS do ?
The distribution of electrical power is often subject to short and long term interference. Using an instantaneous back-up power supply means you can protect your IT system against such interference which can come from the industrial and atmospheric environment, as well as from your own environment. The following table lists the most common sorts of power supply problems, and the consequences for badly protected users:
CAUSES CONSEQUENCES Voltage reduction Due to high voltage consumption required when starting up heavy equipment (motors, escalators, compressors, etc). Keyboard lock, system breakdown leading to data distortion or loss, reduction in equipment performance and lifespan. Excess voltage Lightning hitting power cables or the sudden shutdown of high-consumption equipment can cause temporary voltage increase. Breakdowns, electronic component wear-and-tear, destruction of hard disks. Cut-offs and micro cut-offs There can be many factors: lightning, live-line working, or heavy demand on the electrical network, etc. Data-loss, badly shut-off applications, equipment damage and problems when re-activating applications. Stray There can be many factors: atmospheric conditions, load permutations, generators, radio-emitters, household and industrial equipment. Program and database errors. Shock waves These are generally caused by lightning or when the mains supply is re-established after having been absent during a storm or following a motoring accident. Badly damaged components and equipment, data-loss..
What are the differences between On-line, Off-line or Line-interactive technologies ?
OFF-LINE LINE INTERACTIVE ON-LINE Applications Low power
Service industry with infrequent interference
Recommended for <2kVA power ranges
Service industry with infrequent interference
Medium and high power UPS
Service industry and industrial
Battery transfer time during mains cut-off YES YES NO Frequency control NO NO YES Voltage control YES YES NO Voltage peak absorption NO SOME ALL Normal operational supply Mains Mains UPS Power supply during mains cut-off Battery with <10ms changeover Battery with <4ms changeover Battery without any interruption
Do I need a UPS in addition to a gen-set ?
Yes, for 3 reasons:
• A gen-set supplies current with a high risk of frequency variation. A UPS able to provide perfect quality current is therefore an indissociable complement to a gen-set.
• Supplied equipment may not be able to withstand motor start-up time (about 8-10 seconds).
• The gen-set might not in fact start-up at all. The UPS will, however, ensure supply back up.
Is it necessary to protect a fax machine with a UPS ?
Yes and no. It’s not necessary to protect the fax machine itself, but the modem line needs to be protected against excess voltage, which could damage the device.
What are criteria for choosing a UPS ?
The answer to this question depends on the type of equipment you wish to protect.
YOUR EQUIPEMENT CRITERIA
The UPS should have enough back up to correctly shutdown the PC.
We favour easy implementation (Plug & Play Windows) and ease of integration of the UPS in the office.
Quality of power supply
Certain IT equipment (top-of-the-range workstations, for example) requires good quality current when the UPS is running on battery. We favour a UPS which produces a sine wave out-put signal.
The UPS must be able to control voltage should the variations be too high.
Should the IT system be running on a network, it will be necessary to use software which enables the UPS to be controlled via the network.
CRITICAL APPLICATION SERVER
The availability of a critical server is fundamental to your company. As for a local server, great care must be taken over the quality of the current supplied by the UPS.
Extending back-up time
You could need longer back-up time, therefore it's important to easily add supplementary batteries to your UPS.
The UPS should supply high quality power without any interruption. To guarantee this you should choose a UPS which permanently controls voltage and frequency. Changing over to battery operation should be completely seamless, i.e. without any cut-off.

Is it possible to mount a SIDER COS vertically?
A SIDER COS should never be mounted vertically. This is due to the device being made up of two SIDERs mounted back to back.
You must respect the standard orientation or you can rotate by 180°.
It is possible to defeat the door interlocking in position 1 and 2 with a SIDER COS?
The S type handle enables the defeat of door interlocking in positions 1 and 2.
The use of a tool is required for defeating a door interlocked handle.
Nevertheless, the communication is not working with a computer/PLC or the values are wrong. Why?
Devices communicate through the modbus function 3. The registers have addresses in 5xxxx and not 4xxxx. One word is composed by 2 bytes, with the most significant byte (MSB) at left. These are integers (INT).
One device does not communicate over RS485. Why?
Check the configuration of the device : address, speed, parity, stop bits. Also consult the technical guide about the RS485 wiring
The communication does not work with the Ethernet module of the DIRIS A. Why?
Try to "ping" the DIRIS A to check that the addressing is correct. In general, do not use the DHCP function. Check that there is no firewall on port 502 or 503 between the DIRIS and the computer/PLC
How many devices is it possible to connect in RS485 behind the RS485/Ethernet module of DIRIS A40 (part number 48250204)?
There is no specific rule, the rules of the RS485 apply : max 32 devices without repeater, 247 with repeaters.
After each reboot of the DIRIS A, the default parameters are set again. Why?
There is a profibus module on the DIRIS A, and the parameter "PARA" is set at "YES". Set it to "NO" to avoid this issue.
There is an alarm triangle on the bottom banner of Control Vision. What is it for?
You must use DMT to manage the size of the database and create a new empty database with the device definition
Impossible to read the measurements event history log in Control Vision
You must configure your device in permanent scrolling mode in the device input menu
What are the passwords to have access to the different menus of Control Vision?
The passwords are 2001 for device configuration, 2002 for software configuration, and 2003 for administration and 0 on demo mode
A module is not recognised by the DIRIS A. Why ?
Either the module is for another type of DIRIS A (a module for DIRIS A40 plugged on a DIRIS A20 for example), either the module has been plugged while the Diris was supplied (it is recommended to connect the module when the Diris is not supplied), either one pin of the module connector has been bent/broken when the module has been plugged onto the DIRIS A
How long are values and configuration parameters saved into a DIRIS A?
Current and voltage on the DIRIS are positive, but power is negative. Why?
Current and voltages are shown as RMS values, necessarily positive. Power, on the other side, is calculated out of the phase shift between voltage/current and can be negative. This is mainly due to a wiring error.
The DIRIS does not display single-phase voltages or powers per phase. Why?
This is because it is configured in a three-phase network (3BL/3NBL without neutral). To get single-phase voltages and powers per phases, a neutral is required : therefore a 4BL/4NBL network. Remember that this configuration is not recommended where there is no neutral connected to the DIRIS
The THD of the neutral is over 100 %, whereas the THD of the phases are normal. Why?
This can be normal. The harmonics of rank 3 add up on the neutral, and the fundamentals compensate themselves on the neutral. That's why the ratio harmonics/fundamental can be high on the neutral
What is the IK Index for the SIRCO M polycarbonate enclosure?
IK Index for the SIRCO M polycarbonate enclosure: IK 08

- SIRCO CD315A : 9.5 W/pole
- SIRCO CD400A : 14.4 W/pole
Is there a mechanical locking device for coupling two SIRCO (On rating > 630A)?
Yes you can, BUT only in vertical mounting (one below the other) :
- SIRCO 3 poles : Part Number 27998308
- SIRCO 4 poles : Part Number 2799 8408
What is the maximum number of auxiliary contacts that can be connected to a SIRCO 125A?
For the 125 to 1800A SIRCO range, it depends on the type of contact:
- 2, if using O/C contact
- 4 if using NO + NC contacts
What is the power dissipation (Watts loss/pole) of the SIRCOVER CD 200 A, CD 315 A and CD 400 A?
Watts losses :
- SIRCO CD200A – SIRCOVER CD200A : 4.8W/pole
- SIRCO CD315A : 9.5W/pole
- SIRCO CD400A – SIRCOVER CD400A : 14.4W/pole
In which position can the SIRCO VM1 with direct operation handle be padlocked?
The direct handle can be locked in all 3 positions (0, I, II).
You must remove the plastic spigot to enable locking of the required position (NMO527322).
Customer has a SIRCO VM1 which is operated by an S type handle. While closing the door back onto the extension shaft, the handle became damaged. What is the problem?
The most likely cause is that the switch and handle were not in the same position when the door was re-closed.
You must check that the handle and the device are in the same position before closing.
What is the reference of the 2nd auxiliary contact OF for the steel enclosure rating ≥125A?
The reference of the auxiliary contact is 2999 0012
What is the working mode of our Fan range? Aspiration mode or extraction mode?
The fans are designed for use in aspiration mode
How can we define a regulation?
You can find the rules on how to define a setting in the Application Guide, in the chapter headed "Enclosures / thermal effects"

IEC 61439: structure and scope
The Original Manufacturer guarantees the design and provides the necessary data.
The Assembly Manufacturer is responsible for the complete assembly, especially for the routine tests and any changes in the original system.
Designing and manufacturing an EN 61439 compliant Assembly
Each assembly must have a label indicating the manufacturer, manufacturing references and reference of the standard.
The documentation should provide all electrical interface characteristics (voltage, current, frequency, etc.) and the installation conditions (IP, IK, handling, etc.).
No, this is not a requirement.
Devices, enclosures, busbars, etc., may be of different brands.
The Original Manufacturer has to validate the association.
The integration of a switching device leads to a design verification.
It is possible to create a new functional unit in the assembly system by checking on the one hand its performance in the integration conditions (dimensions, internal temperature, etc.), and secondly by checking the impact of the assembly system (heating, integration rules, etc.).
Adding a Functional Unit to an assembly
Yes, the standard offers two methods of calculation to check assemblies whose incoming current does not exceed 630A and 1600A.
In addition, for all current levels, deductions from similar tested configurations are possible.
Yes, it is possible to validate a design compared to a tested design, provided that the construction and the targeted performance are the same or more favourable.
Verification is carried out by checklist (Table 13 of IEC 61 439-1) or by the calculation method of the IEC 60865-1 standard.
