Warning:

Warning: 1. Ensure personnel have been trained in the handling and proper use of batteries. Always wear the correct personal protection equipment (PPE) when handling batteries. 2. Battery maintenance checks should also be completed as part of your routine maintenance inspections. 3. Always wear the appropriate PPE when handling electrolyte. If splashed with electrolyte, immediately flush the affected area with clean water and seek medical advice. 4. Never add undiluted sulphuric acid to a battery. 5. Keep batteries upright to prevent electrolyte spillage. Electrolyte is a dilute sulphuric acid and is harmful to the skin. 6. Use tools with insulated handles when removing or fitting the battery. Never place tools or metal objects across the battery terminals. 7. During charging, the battery gives off explosive gases. Keep the battery in a well ventilated area and away from naked flames and sparks. Smoking is also prohibited. 8. Generator set batteries, by law, must not be disposed of with household waste. Batteries contain hazardous materials and in the charged state, each cell contains electrodes of lead metal (Pb) and lead (IV) dioxide (PbO2) in an electrolyte of about 33.5% w/w (6 Molar) sulphuric acid (H2SO4). In the discharged state both electrodes turn into lead (II) sulphate (PbSO4) and the electrolyte loses its dissolved sulphuric acid and becomes primarily water.It can be damaging to the environment to send these to landfill, burning batteries can also cause atmospheric pollution.Dealing with lead acid batteries can be hazardous so it is important to follow all safety guidelines. Batteries are an essential part of the generator set and should be maintained appropriately. Keep the battery area clean and dry and ensure any vent caps are tight (if fitted). Clean the battery case with one of the following cleaning solutions: • A mixture of 0.1 kg (0.2 lb) of baking soda and 1 L (1 qt) of clean water • A mixture of 0.1 L (0.11 qt) of ammonia and 1 L (1 qt) of clean water Thoroughly rinse the battery case with clean water. All battery connections must be kept clean and tight. Use a fine grade of sandpaper to clean the terminals and the cable clamps.Clean the items until the surfaces are bright or shiny. Do not remove material excessively. Excessive removal of material can terminal protector to prevent corrosion. The electrolyte level should be covering the plates/grids (1/2 inch / 13 mm) within the battery to maximize full charge transfer. If the liquid level is below the plates/grids, only add distilled water; never add battery acid to top up the volume, as the addition of extra acid will destroy the grids. It is recommended to check the electrolyte and condition of the batteries every 500 running hours. In high ambient conditions, it is recommended to use thermal compensation and check electrolyte levels more frequently, for example every 200 running hours. These checks should also be completed as p...

Control System Of A Gensets

2018-10-08 15:24:06

An electronic control system has been designed and installed to control and monitor the generator set. Depending on the requirements of the Diesel generator set, one of several different standard control systems may be fitted. Other more specialised systems may be fitted for specific installations in which case separate documentation is provided.These control systems consist of three major components working together:

Control Panel – provides a means of starting and stopping the generator set, monitoring its operation and output and automatically shutting down the generator set in the event of a critical condition arising such as low oil pressure or high engine coolant temperature to prevent major damage to the engine / alternator.

Engine Interface Module (where fitted) - provides switching relays for the Starter Motor Solenoid, Glow Plug and Fuel Solenoid. Each of these circuits is protected with individual fuses mounted in the module. Individual LED’s illuminate when each circuit is energised. Power

Output Circuit Breaker - serves to protect the alternator by automatically disconnecting the load in the event of overload or short circuit. It also provides a means of switching the generator set output.
