Страница: 6 / 18

Interconnection Box
There is no interconnection box or junction box provided with the Director Jr. because all of the electronics are
contained in the console. A multiwire cable is provided to connect in any convenient wiring box.
Impulse Meter
An impulse meter is used in the system to measure the amount of fluid dispensed. This meter is actually a
simple flow meter that is installed in the fluid line. Inside the impulse meter is a rotating cam that actuates a
small microswitch that sends electrical impulses to the console. This meter can measure in quarts, pints, liters
or gallons.
INSTALLATION
General
T o 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. will
be 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. systems
will be needed.
2. The number of reels or oil bars and solenoid valves needed will be determined by the number of stations
to be serviced.
3. Decide where to locate the console(s), the reels, and oil bars, and the fluid supply tanks. Once these
locations 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 and
personnel, 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 above
850 psi (56 bar) is relieved. Relief over flow is directed back into the supply container to reduce
the risk of equipment damage or serious bodily injury.
WARNING
!
Plumbing
T he Director Jr. system is a custom assembly tailored to specific needs depending on the relative position of
equipment, 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 from
the pump or source of fluid supply, (Figure 1, Item 6). The meter has 1/2” female pipe threads at both inlet
and 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 movement
or flexing of the inlet line.
To make sure the system is as tamper proof and inconspicuous as possible, the impulse meter can be
installed at any point in the hydraulic line between the fluid source and the first branch of the system. In this
case a short length of hose at one end is suggested to simplify the piping hook-up. A careful study of the floor
plan of the building where the system is to be installed should be made to determine the best location for this
meter, considering ease of installation and length of wiring to the console.
