Une formation incluant des tests de pré-entrée, la ventilation, les procédures d'entrée, les procédures d'évacuation/de sauvetage et des pratiques de travail de sécurité est nécessaire avant d'entrer dans des espaces restreint. Important Note: The following information is provided to guide users of Flo-Dar Sensors on the dangers and risks associated with entry into confined spaces. Remarque importante : Les informations suivantes sont fournies dans le but d'informer les utilisateurs des capteurs Flo-Dar des dangers et des risques associés à l'accès aux espaces confinés. On April 15, 1993, OSHA’s final ruling on CFR 1910.146, Permit Required Confined Spaces, became law. This new standard directly affects more than 250,000 industrial sites in the U.S.A., and was created to protect the health and safety of workers in confined spaces. 6 General information Definition of a confined space: A confined space is any location or enclosure that presents or has the immediate potential to present one or more of the following conditions: • An atmosphere with less than 19.5% or greater than 23.5% oxygen and/or more than 10 ppm Hydrogen Sulfide (H2S). • An atmosphere that may be flammable or explosive due to gases, vapors, mists, dusts or fibers. • Toxic materials which upon contact or inhalation, could result in injury, impairment of health or death. Confined spaces are not designed for human occupancy. They have restricted entry and contain known or potential hazards. Examples of confined spaces include manholes, stacks, pipes, vats, switch vaults, and other similar locations. Standard safety procedures must always be followed prior to entry into confined spaces and/or locations where hazardous gases, vapors, mists, dusts or fibers may be present. Before entering any confined space check with your employer for procedures related to confined space entry. 2.2 Product overview The Flo-Dar Intrinsically Safe Sensor measures the flow velocity and liquid depth in open channels using radar and ultrasonic technology. The unit is designed to withstand submersion during surcharge conditions. The optional surcharge velocity sensor provides velocity measurements during surcharge conditions.

To ensure safety, the installation of instruments in hazardous locations must follow the specifications in the control drawings. Any modification to the instrumentation or to the installation may result in life threatening injury and/or damage to facilities. DANGER Danger d'explosion. Pour assurer la sécurité, l'installation des instruments dans des emplacements dangereux doivent suivre les spécifications dans l'emplacement dangereux indiqué sur la fiche technique. Toute modification de l'appareil ou de l'installation peut conduire à des préjudices constituant un danger de mort et/ou des dégâts sur les installations. The Flo-Dar Intrinsically Safe Sensor is listed as intrinsically safe for Class 1, Zone 1, Group IIB Hazardous Locations. This means that the circuits within these sensors cannot produce a spark or thermal effect that could ignite a mixture of flammable or combustible gases when installed properly. It does not mean that these sensors are explosion proof. If proper safety precautions are not followed, or if the equipment is not installed properly, there is a serious potential for explosion. Be sure to review all safety precautions, installation and wiring practices throughout this manual before installing the Flo-Dar Intrinsically Safe Sensor. 3.1.1 Intrinsically safe installation requirements Installation of this equipment must satisfy local electrical code requirements using the hazardous location control drawings and is subject to final approval by the authority having jurisdiction. Install all associated apparatus, such as the intrinsically-safe barrier, logger or controller in a non-hazardous location. 3.1.2 Hazardous location control drawings DANGER Explosion hazard. Never connect items to the sensor that are not specified on the control drawings. Do not connect or disconnect any equipment unless power has been switched off or the area is known to be non-hazardous. DANGER Danger d'explosion. Ne branchez jamais au transmetteur des éléments ne figurant pas sur la fiche technique. Ne branchez et ne débranchez aucun équipement sans avoir préalablement coupé l'alimentation et vous être assuré que l'environnement ne présentait aucun danger. Follow the control drawings provided (section 3.4 on page 15) and all codes and regulations for connection to the sensor in the hazardous location. 9 Installation 3.2 Sensor installation WARNING Explosion hazard. Installation of equipment into hazardous locations must be done so that no friction can be generated between the Flow Meter and any surrounding surfaces. AVERTISSEMENT Risque d'explosion. L'installation de l'équipement dans des zones dangereuses doit être effectuée de sorte qu'aucun frottement ne soit provoqué entre le débitmètre et toute surface environnante. Mount the Flo-Dar sensor above the open channel on the wall of the manhole. For hazardous locations, a barrier must be installed outside of the hazardous area. To prevent damage to the enclosure, do not mount the Flo-Dar sensor in a location that receives direct sunlight. 3.2.1 Install the frame on the wall DANGER Explosion hazard. Review the safety information in section 2.1 on page 5 and section 3.1 on page 9 before entering a confined space. DANGER Danger d'explosion.

ATTENTION Débranchez toujours l'alimentation de l'appareil avant toute connexion électrique. WARNING Explosion hazard. Voltage connections to the barrier must be from 12 VDC powered loggers. Power can be supplied from a battery or 12 VDC SELV source which has 3rd party NRTL certifications for Canada and the U.S.A., and the correct CE marking and Declaration of Conformity for Europe. AVERTISSEMENT Risque d'explosion. La connections électrique sur le système de barrière de sécurité est seulement possible avec des appareils alimentés en 12VDC. L'alimentation peut venir d'une batterie ou d'une source 12VDC séparée ou très basse tension sécurisée (SELV) qui possède la 3ème partie de certifications NRTL pour le CANADA et USA, et le marquage CE et déclaration de conformité pour l'Europe. 10 Installation 3.3.2 Electrical installation in a hazardous location A barrier with appropriate entity parameters must be installed between the sensor and the logger or controller for installation in hazardous locations. If the SVS option is used, an additional barrier with appropriate entity parameters must also be installed between the SVS component and the logger or controller. 3.3.2.1 Install the barrier A barrier must be installed when the Flo-Dar sensor is installed in a hazardous location as defined in section 3.1 on page 9. A barrier limits the power parameters to the device that is located in the hazardous area. The barrier and the logger or controller must always be installed in a non-hazardous location. The barrier has a dielectric strength of 500 Vrms between the intrinsically safe outputs and the frame of the apparatus. Separation between the intrinsically safe outputs and connections to non-intrinsically safe devices and separation between separate intrinsically safe output channels (power, RS485A and RS485B) should be maintained in accordance with the installation instructions and markings since there is no galvanic isolation between these circuits. Procedure 1. Install the barrier on a wall in a non-hazardous environment (Figure 2 on page 12). 2. Follow the control drawings provided (section 3.4 on page 15) and all codes and regulations for connection to the sensor in the hazardous location. 11 Installation Figure 2 Barrier dimensions 1 12 Desiccant 2 Connector for protective earth ground (PEG) Installation 3.3.2.2 Wiring to the barrier Use the supplied cables for electrical wiring to the barrier. Make sure to install a protective earth ground to the barrier. Procedure 1. Remove the four screws from the cover of the barrier. Remove the cover. 2.

Only qualified personnel should conduct the tasks described in this section of the manual. DANGER Danger d'explosion. Les opérations décrites dans cette section du manuel ne doivent être effectuées que par du personnel qualifié. DANGER Explosion hazard. When using the retrieval pole, make sure to connect the grounding strap to the ground lug on the barrier. The sensor must also be connected to the barrier during maintenance activities. This is to prevent ignition of explosive gases due to static discharge. DANGER Danger d'explosion. Lors de l'utilisation du pôle de récupération, assurez-vous de connecter la languette de mise à la masse à la cosse de masse de la plaque. Le capteur doit également être connecté à la plaque pendant les opérations de maintenance. Ceci sert à éviter d'enflammer les gaz explosifs dus à la décharge statique. The safety provided by the barrier may be impaired if any of the following conditions have occurred: • visible damage • storage above 70 ºC for prolonged periods • exposure to severe transport stresses • previous installation • failure to operate properly If any of these conditions have occurred, return the device to the manufacturer for recertification. WARNING Explosion hazard. To prevent ignition of explosive atmospheres, disconnect power before servicing. AVERTISSEMENT Risque d'explosion. Pour éviter tout risque de déflagration, mettez l’appareil hors tension avant toute intervention d’entretien. This chapter includes only the maintenance information for hazardous location use. For the maintenance information for non-hazardous location use, refer to the Flo-Dar Sensor User Manual. The Flo-Dar sensor contains no user serviceable or repairable components. If service is necessary, the Flo-Dar sensor must be sent to an authorized service center for repair or servicing. 19 Maintenance 4.1 Cleaning the instrument DANGER Explosion hazard. Never attempt to wipe or clean the Flo-Dar or SVS sensor while in a hazardous location. Do not use abrasives or high-pressure hoses or washers to clean the sensors. Do not disturb the pressure port on the bottom of the sensor. DANGER Danger d'explosion. N'essayez jamais d'essuyer ou de nettoyer le Flo-Dar ou le capteur SVS dans un emplacement dangereux. N'utilisez pas de produits abrasifs ou de tuyaux sous pression ou d'appareils de nettoyage pour nettoyer les capteurs. Ne dérangez pas le port sous pression situé dans le bas du capteur. 20 U.S. and countries other than EU HACH COMPANY 4539 Metropolitan Court Frederick, MD, 21704-9452, U.S.A. Tel.
