FOREWORD Each of the Volumes has been prepared in a format to give easy reference to all plant and equipment. Every effort has been made to deal with each system in a concise manner. However, to obtain a full and detailed picture of any particular system or plant item, this manual must be read in conjunction with the record drawings and relevant manufacturer's literature.

To assist in the day to day running of the various plant a description of each is given, together with routine attention necessary to the main components.

Regular inspection, monitoring and checking are necessary if the efficiency and control of plant is to be maintained at the level required.

Regular maintenance and inspections are essential, if inconvenient and costly breakdowns are to be avoided. Although there is no way of guaranteeing against the possibility of breakdown, with regular and detailed inspections together with a preventive maintenance programme, the likelihood of such an occurrence can be greatly reduced.

A correct maintenance programme will also ensure that the individual plant is running at maximum efficiency at all times. This will also extend plant life due to the continual monitoring of wear and changes that the systems undergo during their operating period and life. The maintenance programme will provide anticipated and continuous corrective action to avert and minimise deterioration.

THE MANUAL DOES NOT REPLACE THE NEED FOR FULLY QUALIFIED OPERATORS.

It is important that the modification records in this section are referenced every time that the manual is used in order to ensure that information obtained from other sections is still valid.

All operators must be made fully cognizant with the contents of this manual before operating the system.

SECTION 2

MAINTENANCE & TROUBLESHOOTING 2.1 GENERAL INSPECTION AND MAINTENANCE NOTES

2.1.1 Foreword

Any plant area is potentially dangerous.

(1) Never attempt to stop motive plant that is in the process of slowing down by holding belts or shafts.

The following points should be remembered for day-to-day work.

(2) Ensure that electrical equipment is securely isolated, preferably by the removal of fuses before commencing work.

(3) Always wear protective clothing, overalls, hard-hat, safety shoes, goggles, ear protection etc., relevant to the type of work being carried out.

(4) When working in remote areas, always inform a responsible person of your location and when you expect to return. Always remember to inform that person when you have safely returned, to avoid false alarms.

(5) If possible, remove hand wheels from valves on a system or plant item that has been isolated. This will prevent inadvertent reopening of the valve. This is particularly important when the isolation valves are remote from the place of work. If it is not possible to remove the hand wheel, place a notice on the valve indicating that it is closed for a reason.

(6) Always remember to replace guards and access panels when work is complete.

2.1.2 Electrics ~ General Note

It should be established that the means of protection against direct contact with live conductors is provided by one or more of the following methods:

• Insulation of live parts • Installation of barriers or enclosures • Obstacles

It should be established that the means of protection against direct contact with any live conductors meets the requirements for the safety of any person and property from the effects of electric shock, fire and burns.

For each method of protection against direct contact it should be established that there has been no deterioration of insulation; no removal of barriers or obstacles; no alterations to enclosures or access to live conductors which would reduce its effectiveness.

Precautions should be taken, where necessary, to disconnect electronic and other equipment which may be damaged by subsequent testing. Special care must be taken where electronic components are fitted to protective and control devices, and installed in HF luminaires. If inspection and testing cannot be carried out in any part of the system, or is limited in any way, this should be recorded in the Periodic Inspection Report.

2.1.3 Emergency Maintenance

Depending on the type of breakdown, a decision must be taken on whether the matter is urgent or not, e.g. lamp failure, individual circuit fault or non-essential plant failure. In each of the above cases, the fault needs attention but is not generally considered urgent.

When a breakdown occurs, action is to be taken immediately to render the system safe. In such cases the procedure is outlined in the operation manual for shutting down the system and switching off plant, etc. This must be carried out before any other action necessitated by the breakdown is initiated. This would include work on boilers or pumps, isolation of plant and electrical circuits because of leaks, etc.

Always try to establish the cause of a breakdown rather than merely rectifying the effect. Although the immediate need may be to restore the system to working order without delay, by whatever means possible, never be satisfied with any action which only repairs the defect or replaces the part. Investigation in depth may be required to reveal some underlying fault which, if not corrected, may result in a recurrence of the trouble, or even perhaps later development of other more serious faults which are not yet apparent.

Careful and complete details should be recorded of all breakdowns in a Maintenance Logbook. Date of occurrence and relevant equipment, details of breakdown, any previous maintenance work carried out, previous warnings or evidence of trouble which may (or may not) have been attended to, how the system was operating, any special circumstances, or similar information should be accurately and fully recorded, together with details of action taken, including temporary and/or permanent repairs or replacements. These records are not only useful to the operating staff, but often provide invaluable clues to outside specialists and service engineers.

2.2.3 Maintenance Hazards

• Care should be taken when removing SF6 which may contain decomposition products. It should not be released in an indoor environment and should be collected in a storage vessel. Care should be taken not to breathe SF6 removed from an item of equipment. If this possibility cannot be avoided, a respirator should be worn. This should be fitted with a filter capable of removing the gases described in “arc decomposition products”.

• Enclosures should be evacuated such as to remove as much as possible of the residual SF6.

In some cases, flushing enclosures with dry air

2.2.4 Disposal Instructions

• When the installation has reached the end of its useful life, the equipment should be carefully stripped out and removed from the premises and disposed of in a careful and controlled manner.

• End of life of SF6 - filled equipment SF6 - filled equipment which has been removed from service may require treatment to neutralize any decomposition products remaining after the SF6 has been removed. For environmental reasons. SF6 has to be removed and not released to the atmosphere, (see § SF6 and the global environment). The need for neutralization is dependent on the level of decomposition. Prior to treatment, the SF6 should be removed and stored for recycling. The equipment should then be treated according to the expected decomposition level. After treatment, the equipment can be disposed of as normal waste (respecting local regulations), for example in a landfill site, or subjected to reclamation processes to recover the metals. Solutions used in the neutralization process can be disposed of as normal waste.

Low decomposition:

• No special action is required.

Medium and high decomposition:

• The internal surfaces of gas enclosures should be neutralized using a solution of lime (calcium hydroxide) prepared by diluting 1 kg of lime in 100 liters of water. The enclosure to be treated should, if possible, be filled with the lime solution for a period of 8 hours before emptying. If it is subsequently necessary to work on the enclosure, it should first be rinsed with clean water. For larger enclosures where filling is impractical, powders should be removed, using a vacuum cleaner equipped with a suitable filter, for neutralization separately. The internal surfaces should then be washed with the lime solution which should be left in place for at least one hour followed by rinsing with clean water.

Circuit Breakers

General

• Circuit breakers interrupt electrical current to stop power flow both for switching operations and during fault conditions. Molded case circuit breakers are usually located in low voltage distribution panels and in control boards. These are typically 120-volts alternating current (Vac), 125-volts direct current (Vdc), 240-Vac, and 480-Vac breakers for control, protection, and auxiliary power. Molded case breakers in panel boards should not be loaded more than 80% of rating per NFPA 70B, 11-2.

• Low voltage air breakers are usually located in motor starter cabinets, motor control

centers, station service switchgear, or similar enclosures. These are typically 480 Vac for auxiliary power.

Most breaker maintenance (except infrared scanning) must be performed with equipment de-energized.

UPS (Uninterruptable Power Supply)

General

This section is provided for maintenance technicians. It is assumed that all are familiar with:

• The laws of electricity

• The hazards of working with electricity.

• The basic principles of hybrid diaode-thyristor rectifier bridge technology for battery application.

Equipment

All diagnostic verification can be performed with a multi-meter. The multi-meter must have AC/DC, capability, good accuracy and in some cases, a test clamp attachment.

Preliminary Checks

Always perform a few preliminary checks before starting maintenance:

• General visual inspection of equipment (for signs of overheating or electric discharge).

• Make sure that power is available.

• Attempt to clear the fault by pressing the button “RESET”.

Corrective Action

The charger systems are composed of easy to locate functional modules (power pack, display unit, etc.). Corrective maintenance will usually entail no than changing a module if it is diagnosed as malfunctioning. A minimum recommended set spares should be kept on hand.

Typically, evaluation of the battery voltage/charger output relationship for the giver settings and charge curve will be sufficient to determine whether there is a malfunction.

Keep the following in mind to make a rapid, reliable diagnosis:

• If the equipment is inoperable (for instance if it is not powered), the charge should still operate with its basic functions.

2. Limitation of total current.

3. Limitation of battery current

• The equipment controller determines:

1. Measurement

2. Protection thresholds

3. Secondary charge curve function (equalization, etc.)

Overcharging is usually the result of a control unit malfunction. Undercharging or no charging usually results from a power pack failure (mains fuse, circuit breaker, etc.) or, much rarely, from a control unit failure.


Batteries have to be carefully maintained, frequent visual inspection for spill and bloating of batteries shall be carried out regularly. Cleaning of Corrosion on the enclosure has to be carried out to avoid accumulation.

Electrical Hazards

Battery systems present a risk of electrical shock and high short circuit currents. The following precautions should be observed when installing and maintaining batteries:

1. Remove all personal metal objects (watches and rings).

2. Use insulated tools, Wear full eye protection and rubber gloves.

3. Observe circuit polarities.(do not make or break live circuits)

4. Prior to handing batteries on a metal rack, assure the battery is not inadvertently grounded by measuring the voltage between the battery and the rack. It should be zero. If not, determine the cause and correct prior to proceeding.

Fire, Explosion and Heat Hazards

Lead acid batteries can contain an explosive mixture of hydrogen gas which can vent under overcharging conditions.

Do not smoke of induce sparks in the vicinity of the battery.

Do not install and charge batteries in a seals container.

Mount the individual batteries with 0.5 inches of space between the batteries to allow for convection cooling. If contained, assure the container or cabinet and room have adequate ventilation to prevent an accumulation of potentially vented gas.

If electrolyte contacts the skin, wash immediately and thoroughly. If electrolyte enters the eyes, wash thoroughly for 10 minutes with clean water or a special neutralizing eye wash solution and seek immediately medical attention.

Neutralized any spilled electrolyte with the special solutions contained in a “spill kit” or with a solution of 1lb. Bicarbonate of soda to 1 gallon of water.

Refer to the current issue of the national Electrical Code.


ENVIRONMENTAL COMPATIBILITY, DISPOSAL

• Environmental concerns during development

In contrast to earlier UPS devices, the number of components has been greatly reduced through the use of highly integrated components and modular construction. As a result, energy consumption during production is reduced. Particular attention was paid to reducing the volume, mass and variety of metals and plastics used. Environmental compatibility was an important criterion in the selection of parts obtained from vendors.

• Environmental concerns during production Components obtained from vendors are delivered primarily in reusable packaging. ASIC components and SMD elements are used on the flat component groups. Production is emission free.

• Environmental concerns for disposal The device can be stripped down into recyclable mechanical components with screw and snap connections. Within the area of the EU, disposal should be carried out by a certified disposal company. In other countries local regulations must be observed.

A thorough inspection should always be carried out as soon as possible following a circuit fault. All equipment should be positively isolated and checked to ensure that the supply has been de-energised before any work is carried out on it.


Disposal of Exhausted Lamps - Fluorescent Lamps

Small quantities of linear and compact fluorescent tubes should be broken in the packaging provided with the new lamps, if at all possible, and then disposed of as normal refuse. In the case of large quantities of fluorescent tubes, these must be disposed of in a suitable container and disposed of in accordance with Local Regulations. Care must also be taken, whether large or small quantities are being broken, to avoid flying glass. It is recommended that protective clothing, gloves and eye protectors be worn and the operation should be carried out in a well ventilated area.

Fluorescent lamps are known to release a very small quantity of airborne dust when broken which has the potential to cause respiratory irritation in susceptible individuals. In such cases it is advisable to wear disposable filtered respiratory protection or preferably carry out the task in the open air.

2.5.5 Cleaning of Luminaires

Diffusers and Plastic Controllers

Note: Operatives undertaking the cleaning work should be well instructed and supervised to ensure continuing awareness of the fragility of the louvre optic. This awareness should be maintained throughout the cleaning work, when damage is most likely to occur, and be continued when handling and storing.

Cleaning should be scheduled whenever necessary and co-ordinated with general maintenance if possible. Recommended procedures are as follows:

(1) Wash in a solution of water and domestic detergent

(2) Rinse with clean water after washing

(3) Allow to dry

(4) Apply an anti-static solution to prolong protection against dust contamination

Paint Finished Surfaces

Paint finished surfaces should be cleaned with a solution of water and domestic detergent applied with a cotton cloth. All surfaces should be wiped clean taking care not to scratch the paint finish.

2.8 MAINTENANCE SCHEDULE

2.8.1 Introduction

The schedules indicate the recommended intervals between routine maintenance tasks.

Please note that these are for guidance only. The intervals stated may need to be varied depending upon the age of the plant, usage, etc.

It is advisable to monitor plant operation regularly and maintain an up-to-date logbook. In this way, it will be possible to obtain a reliable indication of the amount of maintenance that the plant requires.

It is important to remember that before work or inspection begins on any item of electrically operated plant, it must be isolated, preferably by removing the fuses in the control panel. Notices must also be posted advising others that the plant is being worked on.

It should be noted that operation of the primary plant serving the works is controlled automatically by the Building Management System and may activate without warning at any time. Check before de-energising the plant whether it is interlinked with other plant (for example duty/standby fans), that may also need to be de-energised.

A basic requirement of any piece of equipment that contains moving parts is correct lubrication. Reference should be made to the manufacturer’s literature and the lubrication schedule contained in this manual for details. Failure to lubricate as recommended will lead to a shortened plant life and premature failure.

Systems will have been balanced to their correct design rates by commissioning engineers. Therefore if it is necessary to alter the set position of a valve, duct damper, etc. or to adjust the speed on a variable speed motor these must all be restored to their previous settings when the maintenance work is complete.
