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.
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 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 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.
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.
Is it necessary to protect a printer with a UPS ?
No, unless it's an industrial-style printer.
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.
ATEX enclosures are intended for use in dusty explosive atmospheres in category 2D. Zone 21 and 22.
Is it possible to force the ATyS 6 to OFF with no source available?
It is possible when an external source, such as a UPS, is provided to supply the ATyS motor.
To remotely order into position 0, you must close terminals 313, 316 and 317.
With an ATyS C30 + ATyS 3s, can all 3 positions be reached via the ATyS D20?
All 3 positions are achievable via the ATyS D20, through the control mode.
What is the maximum length of the remote control cable?
Maximum remote control cable length = 10m.
In case of longer distance, insert control relays.
Is it possible to padlock the ATyS into any position?
In standard products, padlocking is only possible in position 0. For padlocking in all 3 positions, a factory fitted accessory is required which must be ordered at the same time as the switch (see your catalogue).
What is the MTBF (mean time before failure) for the ATyS 6 range?
The MTBF for the ATyS 6 range are :
• ATYS 6 125A to 200A = 8.2 years
• ATYS 6 250 to 400A = 7.4 years
• ATYS 6 630A = 6.6 years
• ATYS 6 800 to 1800A = 8.3 years
Is it possible to perform an emergency stop on a ATyS 6?
The switch can be forced into OFF (emergency stop) by inhibiting automatic operation and then remotely ordering the switch into position 0.
This function can be implemented by the operation of an emergency stop switch connected in circuit with a time relay (t=5s).
Connect terminals 313-317 (inhibit automatic operation) and 316-317 (position 0 order).
Please see the attachement.
Is an ATyS 6e equipped as standard with auxiliary contacts?
The ATyS 6e is supplied as standard with an NO auxiliary contact for each position. Terminal assignment is:
- 13-14 = Position I
- 13-24 Position II
- 13-34 Position 0
In which position is the AUTO/MANU key released?
The key can be removed in either position.
Are the CT inputs of the ATyS 6m insulated through galvanic isolation?
The CT inputs are insulated through galvanic isolation therefore, as a result, the secondary can be earthed.
What are the short circuit characteristics of an ATyS 6m for an operating voltage of 440V?(new)
Since 2003, the electrical network should keep to an operating tolerance of +/- 10%; consequently, our values indicated with 400V are valid up to 440V
Which terminals can be used to indicate when the ATyS is padlocked?(new)
The ATyS 3e, 6e and 6m are equipped with a NO auxiliary contact which closes when the padlocking lever is extended.
The auxiliary contact for padlocking status is located on terminals 53-54.
Which terminals can be used to indicate when the ATyS is in AUT mode?(new)
The ATyS 3e, 6e and 6m are equipped with a NO auxiliary contact which closes when the key is in the AUT position.
The auxiliary contact for AUT status is located on terminals 43-44.
What are the required connections for using an ATyS C30 in a single-phase network with neutral (1BL)?
The internal supply of the controller is fed from terminals 104 and 106.
When it is a single-phase network with neutral (1BL), it is necessary to connect terminal 103 (neutral) to terminal 104.
The supply measurement is taken between terminals 103 and 106.
With regards to space, how many modules are required in order to integrate an ATyS C30 controller into a modular panel?
One module is approx. 17.5 mm wide.
The ATyS C30 is 106 mm wide, which equals 6.05 modules.
7 modules are required.
Under what conditions is the autotransformer required?
When you do not have a neutral connection available.
How can I RESET an ATyS M6s ?
Follow this procedure :
- Place the switch into MANU mode (Open cover).
- Change the DIP SWITCH setting from position A to B position.
- Return the DIP SWITCH from position B back to A position.
- Return the switch to AUTOMATIC mode (Close cover)
The RESET is complete.
Is it possible to fit the bridging bar set into the terminals that have voltage sensing?
No, this is not possible.
The voltage sensing is always upstream of the ATyS, directly on the sources
How does the fault contact on a ATyS M6s function?
It is not a fault contact, it is a "Device Available" contact.
Contact 63-64 closed = Device Available
Contact 63-64 Open = Device NOT Available (in manual mode, no supply available or internal product fault)
What does the Fault LED represent?(new)
There are two possibilities :
- Internal device fault => Return the product for factory assessment.
- Too many switching operations within 1 minute.
What is the difference between an ATyS D10 interface and an ATyS D20?
The ATyS D10 enables source availability and switch position to be displayed on the panel front. Programming is achieved via the ATyS C30 or the ATyS 6.
In addition to the functions of the D10, the ATyS D20 also displays measurements and enables the execution of test and control operations and the programming of the switching system (ATyS C30, ATyS 6).
The display is deactivated on the main products (ATyS C30, ATyS 6) when there is a connection of the remote interface.
What is the minimum permissible time between the opening of a pre-break auxiliary contact and the poles of a switching device?
The minimum time between the operation of the auxiliary contact and the operation of the switch contacts is 20 ms.
Which communication protocol does the ATyS and ATyS M support?

Wrong active and reactive energy values for Countis. Why ?
Do a Wiring test (press the main button for 3s) and check the error number to know which wiring error has been made (see instruction sheet to know the detailed correspondence)
How to protect the Countis E10/E20/E30?
Use 63A (E10/E20) and 100A (E30) gG or aM fuses upstream of the meters
Do we have a solution to meter DC current for Countis?
No, we recommend you put the meter on the AC side of the UPS
On which type of network do the Countis E20/E30 work?
They work on single phase, three-phase with and without neutral networks.
Countis: When should I use MID meters?
European directive transcribed into national laws in the EU countries : its application depends on each country and concerns only the EU. In general, all meters where a financial transaction occurs are concerned. Moreover, even if there is no financial transaction, a MID certified meter is always a better proof than a standard meter.
Countis: Do we have a solution to meter many loads with one single meter?
Yes, with a CT meter (E40/E50) and summation CTs. Remember that this is only possible if the different loads come from the same mains network, and that the voltages are the same.
Can we lock a SIDER COS in position 1 only with a RONIS EL11AP and a locking disc 44098707?
The disc 44098707 contains 3 blocked slots, each dedicated to one switch position (I,0,II). The locking position is configured by opening up (cutting out) the required slot, therefore enabling the choice of locking position.
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?(new)
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.
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
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
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.
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.
How long are values and configuration parameters saved into a DIRIS A?
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
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
A module is not recognised by the DIRIS A. Why ?(new)
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
Current and voltage on the DIRIS are positive, but power is negative. Why?(new)
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.
