Load Share Gateway Overview ≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ The Load Share Gateway (LSG) is a next generation communication converter specifically designed to operate the easYgen-2000 / easYgen-3000 Series and legacy devices ( RS-485 Bus or analog load share line coupled ) in one single load share network Page 6/29 © Woodward Manual 37442 LSG - Load Share Gateway Chapter Installation Safety Precautions ≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ WARNING HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH • Only qualified workers should install this equipment Such work should be performed only after reading this entire set of instructions • NEVER work alone • Before performing visual inspections, tests, or maintenance on this equipment, disconnect all sources of electric power Assume that all circuits are live until they have been completely deenergized, tested, and tagged Pay particular attention to the design of the power system Consider all sources of power, including the possibility of backfeeding • Apply appropriate personal protective equipment and follow safe electrical practices • Turn off all power supplying the equipment in which the LSG is to be installed before installing and wiring the LSG • Always use a properly rated voltage sensing device to confirm that power is off • Beware of potential hazards, wear personal protective equipment, and carefully inspect the work area for tools and objects that may have been left inside the equipment • The successful operation of this equipment depends upon proper handling, installation, and operation Neglecting fundamental installation requirements may lead to personal injury as well as damage to electrical equipment or other property Failure to follow these instructions will result in death or serious injury! WARNING No dead bus closure interlock between easYgen and legacy products is provided by the LSG A closure of the easYgen or legacy product onto a dead busbar simultaneously with other controls must be prevented by external means! The unit does not provide any protection and in addition renders the built-in protection of the easYgen dysfunctional! Regulatory Notes ≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ • The LSG is suitable for use in non-hazardous locations only • The LSG is not authorized for use in life support devices or systems • Wiring and installation must be in accordance with applicable electrical codes in accordance with the authority having jurisdiction • The LSG is designed for installation into an electrical switchboard or cubical as part of a fixed installation © Woodward Page 7/29 Manual 37442 LSG - Load Share Gateway Electrostatic Discharge Awareness ≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ All electronic equipment is static-sensitive, some components more than others To protect these components from static damage, you must take special precautions to minimize or eliminate electrostatic discharges Follow these precautions when working with or near the control Before doing maintenance on the electronic control, discharge the static electricity on your body to ground by touching and holding a grounded metal object (pipes, cabinets, equipment, etc.) Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic materials Wear cotton or cotton-blend materials as much as possible because these not store static electric charges as much as synthetics Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cup holders, cigarette packages, cellophane wrappers, vinyl books or folders, plastic bottles, and plastic ash trays) away from the control, the modules, and the work area as much as possible Opening the Control unit will void the warranty! Do not remove the printed circuit board (PCB) from the control cabinet unless absolutely necessary If you must remove the PCB from the control cabinet, follow these precautions: • Make sure that the unit is completely de-energized (all connectors have to be pulled off) • Do not touch any part of the PCB except the edges • Do not touch the electrical conductors, connectors, or components with conductive devices or with bare hands • When replacing a PCB, keep the new PCB in the plastic antistatic protective bag it comes in until you are ready to install it Immediately after removing the old PCB from the control unit, place it in the antistatic protective bag WARNING To prevent damage to electronic components caused by improper handling, read and observe the precautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed Circuit Boards, and Modules Mounting and Removal ≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ The enclosure provides protection against solid objects according to IP 20 classification and NEMA Type rating When mounting the enclosure observe the following rules: • • • • • • • Avoid splash water and water drops Avoid aggressive gas, steam or liquids Avoid dusty environments Make sure there is sufficient air ventilation and clearance to other devices mounted next to the module Do not exceed the specified operational temperatures Mount inside a sealed electrical switchboard or cubicle Observe applicable local regulations like EN60204 / VDE0113 Page 8/29 © Woodward Manual 37442 LSG - Load Share Gateway Application Overview ≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ The LSG is available in two different types: • Active power load share (P) • Reactive power load share (Q) The following figures show application examples for both LSG types (marked with P or Q) easYgen connected to EGCP-2 (CAN/RS-485) The easYgen devices communicate via CAN bus among each other and therefore can´t communicate directly to EGCP-2 devices which have no CAN bus interface The LSG is able to connect EGCP-2 and easYgen devices in a single load share network easYgen (CAN) The LSG is fixed to work as generator with address 15 and 16 For this reason it is not allowed, to set any other easYgen device to address 15 or 16 (For further information please refer to the easYgen manuals) EGCP-2 (RS-485) The LSG is fixed to work as generator with address For this reason it is not allowed, to set any EGCP-2 to address (For further information please refer to the EGCP-2 manuals) CAN, RS-485 interface and power supply are isolated galvanically, so there is no need for any additional galvanic isolation easYgen Device easYgen Device easYgen Device 2nd Generator 1th Gtor max 30 Generators CAN LSG (P) RS-485 EGCP-2 #1 EGCP-2 #2 EGCP-2 max #7 Figure 2-1: Application – EGCP-2 WARNING Please arrange additional precautions for the dead bus closure interlock The LSG connection doesn´t guarantee a dead bus closure interlock NOTE All easYgen devices which are allowed to perform a dead bus closure, independent of the EGCP-2, must have a generator number
