- Breakaways are required: Install either Model 8701-VV breakaway or Model 807 swivel <br /> breakaway; install using the instructions supplied with the unit. <br /> - The Healy Systems nozzle Model 900 (EVR) series is the only nozzle necessary to <br /> complete the upgrade. Check to be sure the nozzle hook is mounted in the position <br /> shown for Healy nozzles in section 16. Be sure to check for proper fit in the nozzle <br /> holster and that the nozzle can be locked in the off position. Also, be sure that when the <br /> nozzle is locked, that the dispenser cannot be activated from the locked position. <br /> 12. VP1000 THEORY OF OPERATION <br /> The Healy Systems VP1000 is a self-contained rotary vane pump, designed for gasoline vapor <br /> recovery utilizing various parts of the Healy System Vapor Recovery product line. It is intended <br /> for use by either OEM dispenser/pump manufacturers or as an after market add-on to make <br /> existing equipment compatible with Healy System technology. In order to convert to `others' <br /> equipment, an electronic interface is required to adapt the targeted pump/dispenser to the new <br /> vapor recovery equipment. The interface senses when authorization to dispense has been <br /> given and sends signals to the motor to operate at a low speed for one hose, or a higher speed <br /> for two hoses. It also functions to shut off the pump/dispenser if it senses that the vapor pump <br /> is not operating properly. The vacuum is regulated at a level sufficient to clear liquid gasoline <br /> from the vapor path in MPD applications. The Healy nozzle controls the actual amount of <br /> vapors withdrawn, itself, in response to the liquid gasoline flow rate. <br /> MOTOR SPECIFICATIONS <br /> Horsepower 1/8 <br /> Voltage 120VAC <br /> INTERFACE SPECIFICATIONS <br /> Input voltage 120 VAC <br /> Relay current capacity 5AAC <br /> Input signals AC and DC voltages up to 130 VAC max <br /> Motor Input signal 5 VDC @ 20 Hz 50% Duty Cycle <br /> 8-12 <br /> CARO Approved IOM 8-Gilbarco Encore 300 E 500 Series-Executive Orders VR-201 and VR-202 <br />
