  • How to Operate a Wall-Mounted Uninterruptible Power Supply (UPS) Bypass Switch
    Bypass switch must not to be operated if the UPS is in ‘Battery Mode’! Under normal conditions the INPUT and OUTPUT breakers on the external bypass should be closed, this enables the load to be operated through the UPS. • First call your UPS supplier...
  • How to Choose a Suitable Location
    The choice of a particular installation location for the UPS depends on many things: 1.  How much space is available? 2.  Can the floor safely support the weight of the equipment? 3. Will the installation cause continued inconvenience to the existing personnel and business? 4. ...
  • How to Care For a Generator
    General Care Protocol For Generators Prime Rated Generators are designed to run with 10% overload for 1 hour in any 12 hour period. Standby Rated Generators are designed to run at 100% load for the duration of an outage, with no overload available. Load MUST...
  • How Does a UPS Work?
    There are several categories of static UPS systems available. Broadly speaking, UPS Modules fall within one of three operational design architectures, namely off-line, line interactive and on-line. However, irrespective of their individual design criteria certain features are common to all forms of static UPS systems...
  • Generator Exhaust Systems – What Choices Do I Have?
    Factors that govern selection of an exhaust silencer are: 1. Available space. 2. Cost. 3. Noise reduction required. 4. Allowable back pressure. 5. Availability 6. Appearance. 7. Proximity to other components or personnel. As a general rule, an increase in silencer size will improve the...
  • Emergency Power Systems Explained
    Emergency Power Systems are installed to ensure power during a GRID power outage. Emergency Power can be battery or generator power to support, lights, lifts, switches,DATA, critical systems Here we explain each use of Emergency Power: Emergency Lighting Systems Last for up to 4 hours...
  • Diesel Generators – What is Parallel Operation and Load Sharing in Tech Speak?
    When machines are parallel, the magnitude of the field excitation cannot directly influence the output voltage. It does however adjust the internal power factor at which a particular machine operates.  For instance, an over-excited alternator will draw lagging current, whereas an under-excited alternator will draw...
  • Diesel Generators – What About Temperature Issues?
    What to check for if temperature indicator reads too high/low: 1.  Defective temperature indicator. 2.  Temperature bulb not installed into the flow path. Coolant Pressure and/or Level Indicator Fails to Function 1.  Loss of calibration and loose electrical connections due to excessive vibration. 2.  Accumulation...
  • Diesel Generators – Troubleshooting Cooling System Issues
    Diesel Generators can have issues with the cooling systems. Here we offer advice for what to check before calling an engineer. Operator’s Maintenance The most important link in the maintenance chain is the engine operator.  His daily and weekly checks of the cooling system and...
  • Diesel Generators – Starting a Generating Set for the First Time.
    A prime/base load diesel generating set will either have hand or electric starting. On a hand start engine, please refer to the engine instruction book, which will advise on decompression for that specific engine. On electric start units, starting and stopping of the unit is...
  • dBA Generators – What Is It?
    dBA Generators - what is it? dBA in Generators is the term used to calculate noise levels emanating from a working diesel generator. How to Define Noise Levels? Diesel Generator noise levels are calculated in dB(A) and in free field conditions. 'Free field conditions' means what...
  • Diesel Generators – Automatic Load Shedding – Explained
    Automatic load shedding allows diesel generators to be synchronised to start up and then turn off un-requried generators; in effect shedding load. Hence you only use the power required for the site and not over power. This is also a form of resilience N+1. If...
  • Diesel Generators – Fuel and The Fuel System
    Diesel generators burn red diesel fuel. This fuel is generally recommended for diesel generator sets. Red diesel is the term for tax free fuel commonly used in all diesel generators, unless biodiesel is used. A diesel generator's fuel system must supply the diesel engine with...
  • Deep Sea Controllers – How do they operate Diesel Generators?
    Manual Operation 1. Select manual mode. 2. Press the Start push-button to crank the engine; the engine will start and run off-line. When the 'Generator Available' LED is on (after a delay to allow the oil pressure to rise) the generator can be manually switched...
  • Things to Check Before Starting Your New Generator Set
    It is important to read all the instructions contained in the manual, together with those contained in the engine and alternator manuals. These instructions will ensure that the generating set you have purchased will give you satisfactory operation for a long time. The following points...
