Site Preparation and Installat*Instructions • EMC UST Monitoring System SECTION 1. INTRODUCTION A. GENERAL. 1. This manual contains the installation instructions for the EMC UST Monitoring System designed and manufactured for Gilbarco. 2. When a vertical bar I appears adjacent to text or illustra- tions, information has been added or revised in this printing. B. DAMAGE CLAIMS. 1. Thoroughly examine for any damage all components and units as soon as received. •, NOTE: Insist that the carrier's agent verify the inspection and sign the description. 2. Immediately notify the delivering carrier of damage or loss. This notification may be given either in person or by telephone. Written confirmation must be mailed within 48 hours. Railroads and motor carriers are understandably reluctant to make adjustments for damaged merchandise unless inspected and reported promptly. 3. Risk of loss or damage to merchandise remains with the buyer. It is the buyer's responsibility to file a claim with the carrier involved. 4. Immediately advise your Gilbarco representative, distrib- utor, or Giblarco headquarters in Greesboro, NC so that we may assist you. expansion slots (see Figure 2, "EMC Interface Module Area"). Eight slots are available in the Intrinsically -Safe `. Area of a single monitor and any combination of modules may be installed. -- The modules are: • Probe Interface Module. One module accepts inputs from up to four in -tank digital sensing probes. Maxi- mum two modules per system. • Interstitial Sensor Interface Module. One module ac- cepts inputs from ,up to eight interstitial and piping sump liquid sensors. Maximum eight modules per system. • Vapor Sensor Interface Module. One module accepts inputs from up to five monitoring well vapor sensors. Maximum eight modules per system. • Groundwater Sensor Interface Module. One module accepts inputs from up to five monitoring well ground- water sensors. Maximum eight modules per system. 4. Input/Output Functions. C. RETURN SHIPPING. All shipments of Gilbarco pro- ducts must be prepaid. If the sensor is damaged, return it in the original shipping container with shock absorbing mate- rial provided. Gilbarco will accept no liability for damage caused by improper packing. Address the shipment to Gil- 5. barco Inc., 7300 W. Friendly Ave., Greensboro, NC 27420. SECTION 2. PRODUCT DESCRIPTION The EMC Monitoring System features a modular design that allows each system to be configured with monitoring, input and output capabilities according to the needs of a particular site. A. MONITOR. 1. Operating Temperature Range: 32°F to 113°F (0°C to 45°C). Storage Temperature Range: 15°F to 113°F (-10°C to 45°C). 2. Monitor Features. The EMC monitor incorporates the following features (see Figure 1, "EMC Front Panel Features"): • A two-line, 24 -character -per -line Liquid Crystal Display. • A 24 -key front -panel keyboard with control and alpha- numeric functions for programming, operating and reporting. • Three front -panel lamps to provide a visual indication of power -on, warning and alarm conditions. • An internal audible warning and alarm indicator. • An optional integral report printer with built-in take- up spool for hard -copy documentation of inventory, leak detect and alarm information, plus printed reports of all setup information. 3. Monitoring Functions. Monitoring functions such as inventory control, in -tank leak detection, interstitial leak sensing and vapor sensing are provided by modules that snap into intrinsically -safe Input and Output Modules provide for solid-state or switch inputs from external devices and for relay outputs to overfill alarms and external audible and visual warning devices. Slots in the Power Area of the monitor are pro- vided for up to eight Input and Output Modules in any combination (see Figure 2, "EMC Interface Module Area"). The modules are: • Relay Output Module. One board incorporates four Form C output relays fused for 2 Amps. Maximum eight modules per system. • I/O Combination Module. One module incorporates two Form C output relays fused for 2 Amps and two solid-state or switch inputs. Maximum eight modules per system. Communications Interface Functions. Three slots are available in the Communications com- partment (see Figure 3, "EMC Printer and Communi- cations Interface Area") to provide an interface between the EMC CPU, and physically or functionally separate devices such as computers and printers. Any combination of up to three of the available modules may be installed; however, when an integral EMC printer is used, one slot will be occupied by the Printer Interface Module. The external interface modules are: RS -232 Interface Module. Provides a 25 -pin D -con- nector for data transmission — direct via a null modem cable or through an external modem and over phone lines — to a computer, point-of-sale terminal or printing device. Internal Modem Module. A 300/1200 -baud internal modem with twin snap -in RJC111 or Modular jacks for direct data transmission over phone lines. Printer Interface Module. Required for interface between the CPU board and integral printer. B. PROBES. The EMC can accommodate Gilbarco capacitance and mag- netostrictive probes. The installation and wiring procedures for these probes are described in this manual. C. SENSORS. An EMC system can incorporate sensors that detect liquids in interstitial spaces of double-wall tanks and piping sumps of double-wall piping, and detect hydrocarbon vapors in moni- toring wells. Interstitial and piping sump sensors are two -wire devices while vapor sensors are three -wire devices. The installation and wiring procedures for these sensors are described in this manual.
