INSTALLATION

Euro Diesel design the whole installation of the "NO-BREAK KS"® by taking all technical aspects into consideration:

• electrical
• mechanical
• acoustic
• vibration
  

Euro Diesel, if required, will manage the whole installation on a turnkey basis, commissioning and training of local engineers included.

 

MAINTENANCE AND SERVICE SUPPORT

Euro-Diesel equipment is supported by a dedicated service centre based at the head office in Cirencester. Contracted users enjoy a 24 hour all year round response to site service via a manned emergency call centre. The service engineers are equipped with pagers linked to the call centre, an engineer is on call with another on standby at all times. These engineers are directly employed by Euro Diesel (UK) Ltd and we guarantee to visit site within four hours of call out.

A modem facility is offered as an option with the KS systems. This modem (utilising one telephone line supplied by others) will provide a direct communication between the diagnostics of the diesel UPS system PLC and our service centre. Should a fault occur a connection is automatically and immediately made to the service centre where an engineer will diagnose the events that have occurred. Simultaneously the local service engineer will depart to attend site.

Normally each UPS system is equipped with a diagnostic printer (in addition to the usual synoptic of lamps and alarms etc) that will give a print out of the last 200 events on site complete with service instructions. The service support centre also provides a call/data logging facility for long term monitoring and performance analysis.

The maintenance schedule for the No-Break KS consists of two parts, the weekly / monthly test procedure and the six inspection/service visits per year.

1. Self test :

• At a user nominated time every week the system will signal the diesel engine to start and run at operating speed for a nominated period of time and then shut down. This is to confirm the functioning of the battery start system. This is done with no interruption to the critical load or the ability of the system to go to emergency mode in the event of a mains failure.
• At a user nominated time every fifth week the system will signal the diesel engine to start and run as above. Once this has been successfully completed the control system will open the input breaker D1 and give the system an emergency mode load test. This is done with no interruption to the critical load.
• Full system diagnostics are carried out. This procedure has no effect on the critical load or the availability of emergency mode.
  

2. Service Visits :

• 
  ‘A’ Service: Every two months the Euro-Diesel service department visits the site to lubricate the mains shaft bearings. This is done with the system on line with no interruption to the critical load or the ability of the system to go to emergency mode in the event of a mains failure.
• ‘B’ Service: Every six months the Euro-Diesel service department visits the site to lubricate the mains shaft and Accu-Rotor bearings. This is done with the system in bypass mode with no interruption to the critical load; however emergency mode is not available for approximately four to six hours.
• ‘C’ Service: Every twelve months the Euro-Diesel service department visits the site change engine filters and lubricating oil. This is done at the same time as the above bypass period.
• These procedures need two bypass periods per year of four to six hours. No other downtime is needed.

 

SAFE CONTRACTOR SCHEME AND SAFETY PASSPORT

Euro-Diesel (UK) Ltd is one of the latest group of successful companies to join a leading edge scheme to help industry improve its safety record.

SAFEcontractor is a third party accreditation scheme that primarily audits the Health & Safety documentation of contractors.

EDUK achieved registration  from SAFEcontractor ,in October 2005, a programme which recognises very high standards of health and safety practice.

Accreditation is achieved following an assessment of the contractor’s health & safety documentation and compared against the SAFEcontractor Charter standards which set out the health & safety standards required to achieve accreditation.

Safety Passport

All EDUK Engineering Staff hold a current Safety Passport.
The aim of the CCNSG Safety Passport Scheme is to ensure a basic knowledge of health and safety for all site personnel to enable them, after appropriate site induction, to work on site more safely with lower risk to themselves and others.

To obtain a safety  passport EDUK employees have undergone two days H & S training and sat an assessment to demonstrate they have achieved an agreed level of understanding.

 

IMPROVED VIBRATION MONITORING

The Maintenance regime provided by Euro-Diesel (UK) Ltd. is designed to ensure the long service of the KSâ Rotary UPS System. However, mechanical parts do wear and are subjected to stress. Wear to the Accu-rotor or Alternator bearings, if they occur may be gradual or under certain circumstances a bearing may fail within a short period of time. Under the present service regime vibration readings are taken at eight points on the KS machine at each bi-monthly service visit. These readings are then logged at the service centre to provide a long-term trend analysis of the vibration levels in each machine.

Although the present system has proved very effective it cannot predict all bearing breakdowns. To improve our ability to predict bearing wear and thus minimise damage to the machine and prolonged repair time, Euro-Diesel (UK) are offering two solutions:

Continuous Monitoring

ED(UK) has worked closely with a leading condition monitoring equipment provider to develop a system suited to the operation of the KS system.

The new vibration monitoring system uses probes fixed to the KS machine to monitor vibration velocity on a 24/7 basis. The probes are hard wired to a control module in which the probe readings are compared to two pre-set parameters, one for normal mode and one for emergency mode. Alarm signals are generated if the vibration velocity falls outside the relevant parameter. The philosophy includes an inhibited transfer period when the KS machine changes from one mode to the other.

Output from the control module is available as 4-20mA and Volt Free Contacts as standard. The VFC output can be connected to the Series 3 modem to alert ED(UK) of the situation. Connection to your BMS is available from the 4-20mA output, or a repeater relay can be added to allow a VFC connection.

When the vibration monitoring system indicates that an excessive vibration velocity has occurred it is anticipated that a spectral analysis on the KS machine will be carried out to identify the cause of the vibration.
This condition monitoring system is designed to allow the pro-active remedial works to be carried out and if necessary planned replacement of bearings before damage to a bearing causes the KS machine to shutdown. In real term this means that should major repair works to the KS machine be necessary then you are warned in advance and suitable preparations can be made to carry out any works at a time convenient to the customer.

The scope of work involved in this upgrade is as follows:

• 2 vibration sensors per machine.
• 1 dual channel-monitoring module per KS machine giving 4-20mA and alarm relay outputs for each sensor.
• Dual vibration velocity windows for normal and emergency mode.
• Power supply
• Connection to modem
• Interconnecting cabling
• Labour
• Parts & sundry materials
• Technical liaison re connection to BMS and/or alarm system
• Vibration monitoring & commissioning to establish site-specific velocity windows.

Please contact Duncan Carter at the Cirencester office if you require any further information or a quotation for a Continuous Vibration Monitoring System.

Vibration Analysis

EDUK have commissioned the services of a Specialist Engineer in Conditioning Monitoring and have developed specialist training courses for it’s Service Engineers.
The purpose of this service is to provide a diagnostic tool to identify the cause of a suspected or previously detected vibration anomaly. This can be carried out quickly and easily using portable equipment, without intrusion into your user’s critical load support.

Sensing points are fixed to the machine casing and a hand held probe clamps to these sensing points. The clamping action applies the contact force to the sensing point face; this force is then constant not differing with individual technicians, thus ensuring that the reading taken is true and repeatable.

The vibration is analysed by examination of the envelope. From this the peaks can be identified as being from particular bearing components by their frequency and the amplitude compared to the carpet level to ascertain the condition of the bearing component.

Summary

By using the 24/7 vibration monitoring system to detect any vibration anomalies and/or then analysing the vibration signals to ascertain the likely cause of the excess vibration it is possible to predict the oncoming failure of a bearing before it happens and to schedule its replacement before a catastrophic failure occurs. This will reduce the amount of time that the system is out of service and consequentially reduce the time that your user’s load is at risk.

This service is also available to any user for any KS machine and we would recommend that all KS systems over five years old be checked to assess the bearing conditions. The reasons for are four fold:

1. To enable the User or Facility Manager to have a prediction of when bearing changes need to be budgeted for.
2. By incorporating bearing changes in with normal service regime the associated costs can be reduced
3. If bearings are changed before failure the chances of consequential damage within the machine are reduced. For example if a bearing fails replacement of windings may be needed and damage to the main shaft may occur. This will increase the cost of the repair bill by tens of thousands of pounds.
4. This additional safe guard against failure adds to the value of the installation.
