QAS 14 - 20 Pd 1. Safety precautions for portable generators To be read attentively and acted accordingly before towing, lifting, operating, performing maintenance or repairing the generator. 1.1 Introduction The policy of Atlas Copco is to provide the users of their equipment with safe, reliable and efficient products.
Instruction manual 1.3 Safety during transport and installation To lift a unit, all loose or pivoting parts, e.g. doors and towbar, shall first be securely fastened. 1.4 Safety during use and operation 1 When the unit has to operate in a fire-hazardous environment, each engine exhaust has to be provided with a spark arrestor to trap incendiary sparks. 2 The exhaust contains carbon monoxide which is a lethal gas.
QAS 14 - 20 Pd 15 Safety shoes should be compulsory in any workshop and if there is a risk, however small, of falling objects, wearing of a safety helmet should be included. 16 If there is a risk of inhaling hazardous gases, fumes or dust, the respiratory organs must be protected and depending on the nature of the hazard, so must the eyes and skin.
Instruction manual 22 Before clearing the generator for use after maintenance or overhaul, submit it to a testrun, check that the AC power performance is correct and that the control and shutdown devices function correctly. 1.6 Tool applications safety Apply the proper tool for each job. With the knowledge of correct tool use and knowing the limitations of tools, along with some common sense, many accidents can be prevented.
QAS 14 - 20 Pd 2. Leading particulars 2.1 General description The QAS 14 and QAS 20 are AC generators, built for continuous running at sites where no electricity is available or as stand-by in cases of interruption of the mains. The QAS 14 and QAS 20 generators are driven by a fluid-cooled diesel engine, manufactured by PERKINS. An overview of the main parts is given in the diagram below. The generator operates at 50/60 Hz, 230/240 V in line-to-neutral mode and 400/480 V in line-to-line mode.
Instruction manual 2.2 Bodywork Indicates the battery switch The alternator, the engine, the cooling system, etc. are enclosed in a sound-insulated bodywork that can be opened by means of side doors (and service plates). Indicates that the unit may start automatically and that the instruction book has to be consulted prior to use. The recess in the roof has a lifting rod in the middle. ! Never use the guiding rods to lift the generator. Read the instruction manual before using the lifting eye.

QAS 14 - 20 Pd 3. Operating instructions ! In your own interest, always strictly observe all relevant safety instructions. Do not operate the generator in excess of the limitations mentioned in the Technical Specifications. Local rules concerning the setting up of low voltage power installations (below 1,000 V) must be respected when connecting site distribution panels, switch gear or loads to the generator.
Instruction manual The voltage drop across a cable can be determined as follows: 3 ⋅ I ⋅ L ⋅ ( R ⋅ cos ϕ + X ⋅ sin ϕ ) e = -----------------------------------------------------------------------------1000 e = Voltage drop (V) I = Rated current (A) L = Length of conductors (m) R = Resistance (Ω/km to VDE 0102) X = Reactance (Ω/km to VDE 0102) 3.2.
QAS 14 - 20 Pd 3.4.2 During operation Qc1001™ Following points should be carried out regularly: – Check the engine gauges and the lamps for normal readings. ! Avoid to let the engine run out of fuel. If it happened, priming will speed up the starting. – Check for leakage of oil, fuel or coolant. – Avoid long low-load periods (< 30 %). In this case, an output drop and higher oil consumption of the engine could occur.
Instruction manual 4. Maintenance ! Before carrying out any maintenance activity, check that the starter switch is in position O and that no electrical power is present on the terminals. 4.1 Maintenance schedule Service pak Daily - Small Normal Yearly 500 hours 1000 hours 2000 hours 2912 6041 04 2912 6042 05 2912 6043 06 For the most important subassemblies, Atlas Copco has developed service kits that combine all wear parts.
QAS 14 - 20 Pd 5. Storage of the generator 5.1 Storage – Store the generator in a dry, frost-free room which is well ventilated. – Run the engine regularly, e.g. once a week, until it is warmed up. If this is impossible, extra precautions must be taken: - Consult the engine’s operator manual. - Remove the battery. Store it in a dry, frost-free room. Keep the battery clean and its terminals lightly covered with petroleum jelly. Recharge the battery regularly.
Instruction manual 6.4 Alternator trouble shooting Symptom Possible cause Corrective action Alternator does not excite Blown fuse. Replace fuse. Insufficient residual voltage. Increase the speed by 15 %. No residual voltage. For an instant apply on the + and – terminals of the electronic regulator a 12 V battery voltage with a 30 Ω resistor in series respecting the polarities. After being excited alternator does not excite Connections are interrupted.

Instruction manual 7.3.7 Electronic speed regulator The electronic speed regulator makes sure that the output frequency of the generator is 60 Hz, independent of the amount of load. The accuracy at constant load is ± 0.25%. 7.3.8 7.3.10 Earth leakage relay The “Earth relay” option provides a detector that will trip the main circuit breaker Q1 when an earth fault current is detected. Low voltage (LV) The "Low voltage" option allows to run the unit at low voltage (= high current).
QAS 14 - 20 Pd 7.3.11 IT-relay 7.3.12 “Electricité de France” (EDF) The generator is wired for an IT network i.e. no supply lines of the power supply are directly earthed. A failure in insulation resulting in a too low insulation resistance, is detected by the insulation monitoring relay. When the EDF-option is installed, the unit operates as a standard unit when the neutral and the PE terminals are connected to each other (see figure below).
Instruction manual 7.4 Overview of the mechanical options The following "mechanical" options are available for the QAS 14 and QAS 20 units: When using this option, make sure to connect the fuel supply line as well as the fuel return line. Connections to fuellines ought to be air-tight to prevent air from entering the fuel system. Indicates the fuel supply line from the tank to the engine.
QAS 14 - 20 Pd 7.5.3 Wheel chocks The option “wheel chocks” allows to park the generator on sloping ground. Place wheel chocks in front of or behind the wheels to immobilize the generator. 7.5.4 Lighting tower The "Lighting tower" option provides an undercarriage (frame, axle and towbar) and 6 halogen projectors of 1500 W each. The lighting tower is very useful for construction sites where no electricity nor lighting is available. Before raising the tower, install the four props for stability.
