Higher voltage will damage the transmitter. Wiring between the power supply and the Eclipse transmitter should be made using 18–22 AWG shielded twisted pair instrument cable. Within the transmitter enclosure, connections are made to the terminal strip and the ground connections. The directions for wiring the Eclipse transmitter depend on the application: • General Purpose or Non-incendive (Cl I, Div. 2) • Intrinsically Safe • Explosion Proof WARNING! Explosion hazard. Do not disconnect equipment unless power has been switched off or the area is known to be non-hazardous. 2.5.1 General Purpose or Non-Incendive (Cl I, Div. 2) A general purpose installation does not have flammable media present. Areas rated non-incendive (Cl I, Div. 2) have flammable media present only under abnormal conditions. No special electrical connections are required. Caution: If flammable media is contained in the vessel, the transmitter must be installed per Cl I, Div. 1 standards of area classification. Black (-) Red (+) (+) (-) Wiring Diagram To install General Purpose or Non-Incendive wiring: 1. Remove the cover to the wiring compartment of the transmitter. Install the conduit plug in the unused opening. Use PTFE tape/sealant to ensure a liquid-tight connection. 2. Install a conduit fitting and pull the supply wires. 3. Connect shield to an earth ground at power supply. 4. Connect an earth ground wire to the nearest green ground screw (not shown in illustration). 5. Connect the positive supply wire to the (+) terminal and the negative supply wire to the (-) terminal. 6. Replace the cover to the wiring compartment of the transmitter. 57-600 Eclipse Guided Wave Radar Transmitter 17 2.5.2 Intrinsically Safe An intrinsically safe (IS) installation potentially has flammable media present. An approved IS barrier must be installed in the non-hazardous (safe) area. See Agency Drawing – Intrinsically Safe Installation, Section 3.4.2. To install Intrinsically Safe wiring: 1. Make sure the IS barrier is properly installed in the safe area (refer to local plant or facility procedures). Complete the wiring from the barrier to the Eclipse transmitter. 2. Remove the cover to the wiring compartment of the transmitter. Install the conduit plug in the unused opening. Use PTFE tape/sealant to ensure a liquid-tight connection. 3. Install a conduit fitting and pull the supply wires. 4. Connect shield to an earth ground at power supply. 5. Connect an earth ground wire to the nearest green ground screw (not shown in illustration). 6. Connect the positive supply wire to the (+) terminal and the negative supply wire to the (-) terminal. 7. Replace the cover to the wiring compartment of the transmitter. 2.5.3 Explosion Proof (-) negative (+) positive – + Power Supply 24 VDC Explosion Proof (XP) is a method of designing equipment for installation in hazardous areas. A hazardous location is an area in which flammable gases or vapors are, or may be, present in the air in quantities sufficient to produce explosive or ignitable mixtures. The wiring for the transmitter must be contained in Explosion Proof conduit extending into the safe area. Due to the specialized design of the Eclipse transmitter, no Explosion Proof conduit fitting (EY seal) is required within 18" of the transmitter. An Explosion Proof conduit fitting (EY seal) is required between the hazardous and safe areas. See Agency Specifications, Section 3.4.1. To install Explosion Proof wiring: 1. Install Explosion Proof conduit from the safe area to the conduit connection of the Eclipse transmitter (refer to local plant or facility procedures). 2. Remove the cover to the wiring compartment of the transmitter. 3. Connect shield to an earth ground at the power supply. 4. Connect an Earth ground wire to the nearest green ground screw per local electrical code (not shown in illustration). 5. Connect the positive supply wire to the (+) terminal and the negative supply wire to the (-) terminal. 6. Replace the cover to the wiring compartment of the transmitter before applying power. 57-600 Eclipse Guided Wave Radar Transmitter – + Test Current Meter Current Meter G.P./I.S./Explosion Proof Model 18 2.6 Configuring the Transmitter The Eclipse transmitter comes configured from the factory but can be reconfigured easily in the shop (disregard error message due to unattached probe). Bench configuration provides a convenient and efficient way to set up the transmitter before going to the tank site to complete the installation. Before configuring the transmitter, collect the operating parameters information (refer to Section 1.1.2). Power up the transmitter on the bench and follow through the stepby-step procedures for the menu-driven transmitter display. Information on configuring the transmitter using a HART communicator is given in Configuration Using HART, Section 2.7. Information on configuring the transmitter using FOUNDATION fieldbus is given in Section 2.8. Refer to instruction manual 57-640 for detailed FOUNDATION fieldbus information. (-) negative (+) positive 2.6.1 Operating Parameters – + Some key information is needed to calibrate the Eclipse transmitter. Complete the configuration information table in Section 1.1.2. Power Supply 24 VDC 2.6.2 Setting Up for Bench Configuration – + Test Current Meter Current Meter G.P./I.S./Explosion Proof Model The Eclipse transmitter can be configured at a test bench by connecting a 24 VDC power supply directly to the transmitter terminals as shown in the accompanying diagram. An optional digital multimeter is shown if current measurements are desired. NOTE: Current measurements taken at these test points is an approximate value. Accurate current readings should be taken with the digital multimeter in series with the loop. 1. When using a HART communicator for configuration, a minimum 250 Ω line load resistance is required. See the HART communicator manual for more information. 2. The transmitter can be configured without the probe. (Disregard the error message due to the unattached probe.) 3. After entering the last value, allow 10 seconds before removing power from the transmitter. This allows the transmitter to store values. 57-600 Eclipse Guided Wave Radar Transmitter 19 2.6.3 Transmitter Display and Keypad The Eclipse transmitter has an optional liquid crystal display (LCD) capable of showing two lines of 8 characters each. Transmitter measurements and configuration menu screens are shown on the LCD. The transmitter default display is the measurement screen. It cycles every 5 seconds to display STATUS, LEVEL, %OUTPUT, and LOOP information (LEVEL, %OUTPUT, and STATUS for Fieldbus version). The transmitter defaults to this display after 5 minutes if no keystrokes are sensed. The keypad has three arrows used to scroll through the displays and to calibrate the transmitter. The Up and Down Arrow ( ) keys and the Enter ( ) key. Arrows Function in Display Mode Function in Configuration Mode Increases or decreases the value displayed or moves to another choice. NOTE: Hold arrow key for rapid scrolling. Enter Down Up Up and Down Moves forward and backward in the configuration program from one display to another. Á Enter Enters the configuration mode Accepts a value and moves (noted by an exclamation point to the next step of the as the last character in the top configuration program. display line). 2.6.4 Password Protection (Default = 0) The Eclipse transmitter is password protected to restrict access to certain portions of the menu structure that affect the operation of the system. When the proper password is entered, an exclamation point (!) appears as the last character of the first line of the display. The password can be changed to any numerical value up to 255. The password is required whenever configuration values are changed. The default user password installed in the transmitter at the factory is 0. The last step in the configuration menu provides the option to enter a new password. With a password of 0, the transmitter is no longer password protected and any value in the menu can be adjusted without entering a confirming password, except diagnostic values. NOTE: If the password is not known, the menu item New Password displays an encrypted value representing the present password. Call the factory with this encrypted value to determine the present password. 20 57-600 Eclipse Guided Wave Radar Transmitter Á Á Á Á Á 2.6.5 Model 705 Menu: Step-By-Step Procedure The following tables provide a complete explanation of the software menus displayed by the Eclipse transmitter.
