Interconnection BoxThere is no interconnection box or junction box provided with the Director Jr. because all of the electronics arecontained in the console. A multiwire cable is provided to connect in any convenient wiring box.Impulse MeterAn impulse meter is used in the system to measure the amount of fluid dispensed. This meter is actually asimple flow meter that is installed in the fluid line. Inside the impulse meter is a rotating cam that actuates asmall microswitch that sends electrical impulses to the console. This meter can measure in quarts, pints, litersor gallons.INSTALLATIONGeneralTo determine the installation requirements for a Director Jr. system(s), certain factors need to be established.In general, these factors will determine how much material such as cable wire, fluid lines, pumps, and etc. willbe needed. Answers to these questions below will help determine your material requirements.1. Determine how many fluid types are to be dispensed. This will determine how many Director Jr. systemswill be needed.2. The number of reels or oil bars and solenoid valves needed will be determined by the number of stationsto be serviced.3. Decide where to locate the console(s), the reels, and oil bars, and the fluid supply tanks. Once theselocations are established, the lengths of wire, cable, and fluid lines can be determined.A pressure relief valve at the fluid supply point is mandatory for protection of the system andpersonnel, and to maintain the warranty in effect. Relief Kit 3120-085 (1/2” NPT) or 3120-086 (3/4”NPT) will protect the system from possible overpressure damage. Excess fluid pressure above850 psi (56 bar) is relieved. Relief over flow is directed back into the supply container to reducethe risk of equipment damage or serious bodily injury.WARNING!PlumbingThe Director Jr. system is a custom assembly tailored to specific needs depending on the relative position ofequipment, the number of products controlled and the number of stations for each product. To control a prod-uct which will be monitored, an electric impulse meter will be installed in the main hydraulic line coming fromthe pump or source of fluid supply, (Figure 1, Item 6). The meter has 1/2” female pipe threads at both inletand outlet. It is recommended that the meter be installed on a rigid line which will give it support. It is recom-mended that a flexible hose be attached between the pump and the meter. This will allow for slight movementor flexing of the inlet line.To make sure the system is as tamper proof and inconspicuous as possible, the impulse meter can beinstalled at any point in the hydraulic line between the fluid source and the first branch of the system. In thiscase a short length of hose at one end is suggested to simplify the piping hook-up. A careful study of the floorplan of the building where the system is to be installed should be made to determine the best location for thismeter, considering ease of installation and length of wiring to the console.5 |
