    SAFETY Users of ESAB welding equipment have the ultimate responsibility for ensuring that anyone who works on or near the equipment observes all the relevant safety precautions. Safety precautions must meet the requirements that apply to this type of welding equipment. The following recommen- dations should be observed in addition to the standard regulations that apply to the workplace.
  • Page 12 WARNING ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAU- TIONS WHEN WELDING. ASK FOR YOUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE BASED ON MANUFACTURERS’ HAZARD DATA. ELECTRIC SHOCK - - Can kill Install and earth the welding unit in accordance with applicable standards. Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.

  • Page 18: Function Description (Circuit Board)

    FUNCTION DESCRIPTION (CIRCUIT BOARD) Serial buss General The drive unit consists of two circuit boards, named NME (AP2) and DC DUO (AP1). (See Page 16 and Page 17 for component positions on the circuit boards.) The NME board deals with all communication with the higher level system via a two--wire serial bus.

  • Page 19: Dc Duo (Ap1)

    DC DUO (AP1) The DC DUO circuit board can be divided into five function blocks: 1. Internal power supply Generates the necessary power supplies for the electronic circuitry. 2. The processor (IC300) Controls the motors and communication with the NME circuit board. The microprocessor controls the motors by measuring their armature voltages, the available DC bus voltage and the motor currents.

  • Page 20: Test Points

    TEST POINTS Testing the external power supply (from the welding power source) Measure the voltage at contact K13. The approved value range for the voltage is 37,8 V 46,2 V ± ± Testing the internal power supply voltages The following test measurements can be made when the motor is not running. Connect a voltmeter across the following components (negative to GND) : Set value Approved value range...

  • Page 21: Checking That The Program Is Running

    Checking that the program is running Measure the signal on K3:12 using an oscilloscope, and make sure that it is constant at +5V. If the program is not running normally, the signal will go low. The software will then perform a reset and the signal will again go high. Checking NO.

  • Page 22: Installation

    INSTALLATION General The incoming power supply (42 V AC) to the A2--A6 Process Controller (PEH) is obtained from the welding power source via the control cable, which also carries the bus communication between the two units. See the connection diagram on page 14. Internal connections Connect incoming cables to the 12--pole connector (XS1) and the circuit board contacts on the inside of the control unit.
