SAFETY SUMMARY

The following are general safety precautions that are not related to any specific procedures and therefore do not appear elsewhere in this publication. These are recommended precautions that personnel must understand and apply during many phases of operation and maintenance.

KEEP AWAY FROM LIVE CIRCUITS: Operating personnel must at all times observe all safety regulations. Do not replace components or make adjustments inside the equipment wUh the high voltage supply turned on. Under certain conditions, dangerous potentials may exist when the power control is in the off position, due to charges retained by capacitors. To avoid casualties, always remove power and discharge and ground a circuit before touching it.

DO NOT SERVICE OR ADJUST ALONE; Under no circumstances should any person reach into or enter the enclosure for the purpose of serviclng'or adjusting the equipment except in the presence of someone who is capable of rendering aid.

RESUSCITATION: Personnel working with or near high voltages should be familiar with modern methods of resuscitation. Such information may be obtained from the Bureau of Medicine and Surgery.

The following WARNINGS appear in the text in this volume and are repeated here for emphasis.

WARNING WARNING

Observe caution during the performance of the following procedures. 115-volt, 60-HZ power is connected to components of the TLI system even though power is turned off at the components.

Equipment and accessories used in typical system arrangements are shown in figure 1-1. This manual describes the operation, theory of operation, preventive and cor rective maintenance procedures, troubleshooting, installation, and physical and technical characteris tics for the components that can be selected to form any given TLI system. An illustrated parts list is also provided for the identification and location of the repair parts for the equipment and accessories in cluded in a system.

1-3. Chapter 1 describes the purpose of TLI systems and includes physical descriptions and a list of tech nical characteristics. Equipment, accessories, and documents that can be supplied as part of a system are listed. In addition, those equipment and acces sory items that are required to install, operate, and maintain the system, but which are not supplied, are listed.

1-4. PURPOSE OF EQUIPMENT.

1-5. TLI systems provide a means of determining the level of fluids stored in shipboard fluid tanks.

The level of the fluid is indicated on meters contained in system components distributed throughout the ship.

Meter deflection is continuous, in incremental steps, or in a combination of both.

1-6. Electrical signals representing the fluid level that has been detected can also be examined to deter mine whether the fluid level lies within predeter mined values in the associated tanks. If the fluid level falls below or rises above these predetermined values, audible, visual and/or electrical signal alarm Indications can be provided at TLI system components and/or at other shipboard locations.

1-7. PHYSICAL DESCRIPTION.

1-8. GENERAL. TLI system components can be divided into four general categories: fluid level de tection devices, receiver devices, remote alarm and fluid level indicating devices', and installation acces sories. Descriptions of the types of equipment avail able within each category follow.

1-9. FLUID LEVEL DETECTION DEVICES. Fluid level detection devices are installed in the fluid tanks of the ship, serving as transducers that convert the fluid level in the tank to an electrical signal. Trans ducers of two types are available, transmitters (which provide a continuous tank level signal) and level links (which provide tank level signals repre senting specific increments of fluid level). Cable assemblies associated with the fluid level detection devices connect transmitters or level links to other transmitters or level links, to ship's wiring, to re ceivers, and/or to each other.

1-10. Transmitters. One or more of six basic trans mitter types may be used singularly or in combination with level links to form a fluid level detection device for a fluid tank. The number of transmitters and the type used are determined by the height of the fluid tank and by the nature of the fluid level indication that is required. Each of the six transmitter types, (figure 1-2) consists of a network of voltage divider resistors a!nd magnetic reed switches which are con tained in silicon rubber potted in a mylar tube that is surrounded by a neoprene tube and all mounted in a stainless steel tube. Electrical leads connecting to the resistors and magnetic reed switches are brought to electrical connectors located at the top, bottom, or both ends of the transmitter.

1-11. A cylindrical float assembly located on the stainless steel tube is free to move up and down the tube within limits established by retaining rings or pairs of brackets that are integral with the transmit ters. The bracket pairs or circular flanges on the tube are used as mounting surfaces for the installation of transmitters in the fluid tank.

1-12. Transmitter types XM-36470 and XM-36475 are similar in construction and application. Each of these types is constructed for a flange-mounted ap plication. In flange-mounted installations, the float assembly on the transmitter is free to rise to the top of the tank and thereby can be used to indicate the level of fluids that rise as high as the top of the tank.

Transmitter type XM-36470 is a bottomed transmit ter; that is the bottom surface of the transmitter is sealed making it applicable to a single-transmitter installation. Transmitter type XM-36475 is a trans fer transmitter; that is, the bottom of the unit is not sealed, but is terminated in an electrical connector for connection to a cable assembly that runs to another transmitter in a multi-transmitter installation.

1-13. The other four transmitter types shown in fig ure 1-2 incorporate a pair of brackets and are in tended for bracket mounting. Transmitter types

Figure 1-2. Transmitter TVpes

XM-36460 and XM-36480 are bottomed transmitters and, therefore, are used in single-transmitter in stallations. Since Type XM-36460 has its electrical connector at the top of the transmitter, the float is unable to rise to the full height of the unit. This transmitter type is therefore used in those single transmitter installations in which it is required to indicate fluid levels at the bottom of the tank, but not at the very top of the tank. The point of maximum level indication lies below the top of the fluid tank.

Type XM-36480 is an inverted version of the XM- 36460; that is, it is designed for Installation with its electrical connector at the bottom of the unit. The type XM-36480 is therefore used in single-transmit ter installation in which fluid levels at the top of the taiik can be indicated, but fluid levels can be indicated only to a minimum point that lies above the bottom of the tank.

1-14. Transmitter types XM-36465 and XM-36485 are used in multiple-transmitter installations. Both types contain additional internal magnetic reed switches that enable the use of these transmitters with other transmitters in the same fluid tank installation. These switches provide a transfer function when the fluid level rises or falls within an area of transmitter over lap. The type XM-36465 transmitter has electrical connectors at both ends, permitting its use as an in termediate transmitter between upper and lower trans mitters. The type XM-36485 is an inverted transfer transmitter and therefore serves as the top transmit ter in a multiple-transmitter installation.

1-15. Level Links. One or more of four basic level link types can be used alone or in combination with transmitters to form a fluid level detection device.

Hie type of level link used in any installation is deter mined by the type of level-link transmitter combina tion that is to be instaUed. Type LL-35801 is used for installations in which a level link by itself forms the fluid level detection device. (See figure 1-3.)

Type LL-35802 is used for installations in which the level link is located at the bottom of a fluid tank and is combined with one or more transmitters installed above the level link. Type LL-35803 is used for in stallations in which the level link is located at the top of a fluid tank and is combined with one or more transmitters below the level link. Type LL-35804 is used for installations in which a level link serves as an intermediate fluid detection device with one or more transmitters located above and below the level link.

1-16. Each level link is comprised of a number of cable-connected station assemblies. The number of station assemblies in a level link is determined by the height for which incremental fluid level indication is required. Individual station assemblies include a magnet-equipped float that rides up and down on a stem. The stem houses a resistor, magnetic reed switches, and semiconductor diode. A mounting bracket on the stem permits individual installation of ea6h station assembly.

1-17. Level link type LL-35801 is terminated at one end by a penetration cable that passes through the fluid tank bulkhead and at the other end of the bottom most station assembly by a molded diode assembly.

(See figure 1-4.) Level link type LL-35802 substi tutes a connector and adaptor in place of the penetra tion cable of type L L - 35801 to permit electrical con nection to a transmitter. Level link type LL-35803 has the penetration cable at the same location as type LL-35801, but substitutes electrical connector for the molded diode assembly to permit connection to a lower transmitter. Level link type LL-35804 is ter minated at both ends by electrical connectors to per mit connection to transmitters above and below the level link.

1-18. Cable Assemblies. Five types of cable as-semblies are used in fluid detection devices to pro vide electrical connections between transmitters and/ or level links inside of a fluid tank and to ship's wir ing, J-boxes, or receivers outside of the fluid tank.

(See figure 1-5.) Connections between two transmit ters or a transmitter and a level link are described as jumper connections; connections between a trans mitter or a level link and a component outside of the fluid tank are described as penetration connections (the connection provides penetration of the fluid tank bulkhead). Cable assembly type 36880 is a penetra tion cable assembly. It is terminated at one end by an electrical connector whereas the other end has loose electrical leads that connect to terminals on a

J-box or receiver terminal board. Cable assembly type 36885 is terminated at both ends by electrical connectors to permit its use as a jumper connection between two transmitters. Cable assembly type 36890 is a T-shaped cable assembly that is terminated at two ends by electrical connectors and has loose leads at the third. Type 36890 serves as a combined jum per and penetration connecting device that is normal ly used with inverted transmitters. Cable assembly type 36889 is similar to cable assembly type 36885 described above, but uses a different electrical con nector suited to high-pressure applications. Cable assembly type 37890 is similar to cable assembly type 36890; however, the loose ends of the type 36890 are terminated on the type 37890 by an electrical con nector suited to high-pressure applications.

1-19. RECEIVER DEVICES. Receiver devices, mounted on ship's bulkheads and in equipment panels aboard ship, convert the electrical signals generated by the fluid level detection devices to deflections on meters usually calibrated in gallons. Some receivers also examine electrical level signals to develop an alarm condition if the fluid level in the tank rises above or falls below preselected heights in the fluid tank. Alarm generating receivers actuate relay con tacts to indicate the existence of an alarm condition, and in some cases, provide visual and audible indica tions of an alarm condition.

1-20. Two categories of receiver devices are avail able for use with a TLI system: one category includes receiver modules, the other receiver panels. Each receiver module performs level indication, alarm generation, and/or alarm indication functions for one fluid tank. Each receiver panel provides the three functions for from 4 to 15 fluid tanks.

1-21. Receiver Modules. Receiver modules are rectangular box-like units that are rack-mounted for installation in an equipment panel or a bulkhead. (The mounting racks for receiver modules are described in paragraph l-37g.) Three groups of receiver modules (figure 1-6) are available for use in a TLI system: one group indicates fluid level on 4-1/2-inch square-shaped meters; a second group that Indicates fluid level on 5-inch eclgeview meters; and a third group consisting of only one receiver module type which has no fluid level meter. The third group, a multi-alarm indication receiver module is described under the heading of remote alarm and fluid level in dicating devices. (Refer to paragraph 1-31.)

1-22. Within each of the first two groups of receiver modules, four variations are used to determine the functions performed. This receiver module, like all receiver modules that perform the level indication function by processing signals from the fluid level detection devices, is called a primary receiver. No-alarm receiver modules with Parts No. 31326 and 31340 for 4-1/2-inch square and edgeview meters, respectively, provide a level indication function only.

Diuil-alarm receiver modules with Parts No. 31320 and 3i?<{0 add either one or two alarm generating capabilities to the level indication function, the quan tity determined by the number of alarms (single or dual) specified during procurement. Alarms are generated at dual-alarm receiver modules when fluid

Figure 1-6. Receiver Module Types levels exceed selected high or low values or when either condition is detected in same tank. These alarms take the form of relay contact closures that are associated with a high-level alarm or low-level alarm, as applicable. HI-LO alarm receiver modules with Parts No. 37030 and 38330 add one or two alarm indication capabilities to the level indication and alarm generating function, the quantity determined during procurement. Alarm indications are pro duced in the form of lamp illuminations that identify the type of alarm (adjustable high-level or low-level).

A relay contact closure developed by HI-LO alarm receiver modules indicates the presence of an alarm, only, without identifying whether the alarm is pro duced by a high-level or low-level condition. This closure is used to sound an alarm horn or bell. Sec ondary receiver modules, Parts No. 31330 and 31370 are slave units which produce fluid level meter deflections only. Secondary receiver modules con tain no electronic circuits other than fluid level meters and so are unable to process signals coming from fluid level detection devices. They, therefore, are slaved to receiver modules of other types.

1-23. Receiver modules have operating controls and indicators mounted on the front panel. On receiver modvdes with alarm functions, adjustment controls are accessible on the right side panel. Electrical connections are made to connectors on the rear bottom of the units. All electrical parts are accessible for maintenance purposes when the right side panel is re moved.

1-24. Receiver Panels. Receiver panels are box-like units that are mounted to bulkheads using flanged sec tions welded to the top and bottom of the box. (See figure 1-7.) As in the case of receiver modules, re ceiver panels are available with either 4-1/2-inch square fluid level meters or edgeview meters. Indi vidual receiver panel types vary, not only in the types of meter used to indicate fluid level, but in the number of fluid tanks for which fluid-level indications and alarm functions can be provided. Receiver panels with Parts No. 37040 and 38340 process signals for four to seven fluid tanks, each; receiver panels with Parts No. 37050 and 38350 process signals for 8 to 11 fluid tanks, each; and receiver panels with Parts No.

37060 and 38360 process signals for 12 to 15 fluid tanks.

1-25. Fluid level meters for each fluid tank being indicated are located on a hinged front cover. When any given receiver panel is associated with a number of fluid tanks that is less than its capacity, a blank plate is installed in place of meters that are not re quired. Two indicating lamps are mounted above each meter to indicate the detection of alarm condi tions, when applicable. Operating controls that are common to all fluid tank circuits on the receiver panel are located at the lower right portion of the cover.

1-26. When captive screws on the hinged cover are released, the cover can be opened to make the elec trical parts of the receiver panel accessible for maintenance purposes. These parts are mounted on the cover, the interior rear wall of the receiver panel box, and on printed circuit board modules housed in one or two circuit board racks. (See figure 1-8.)

One printed circuit board rack is supplied when eight or less fluid tanks are serviced, two for twelve or more. One printed circuit board control module is provided for each active meter on the receiver panel.

The functions performed by different control modules are determined by the requirements of the fluid tank being processed. (Refer to paragraph 1-28.) In addi tion to the control modules provided for each meter, each receiver panel also contains one or two power supply and master alarm modules and may contain one or two flasher and full-wave bridge rectifier modules. (Flasher and full-wave rectifier modules are optional equipment.) Two modules of the types indicated are used on those receiver panels that are associated with twelve or more fluid tanks.

1-27. Electrical connections to the receiver panel are made to terminal board strips mounted on the rear interior wall of the box. One terminal board strip is associated with each fluid tank, one with in put power, one with each group of eight control

CATING DEVICES. Remote alarm and fluid level in dicating devices are devices that contain alarm bells or lamps to indicate the detection of a high or low fluid level alarm by a receiver module or receiver panel, and in one case, a portable fluid level meter that serves as a portable secondary receiver. De scriptions of the remote alarm and flidd level indi cating devices that are available for use with a three-wire tank level indicating system are contained in the following paragraphs.

1-31. Multi-Alarm Indication Receiver Module. The multi-alarm indication receiver module (figure 1-10) is contained in the same modular box-like case as the receiver modules described in paragraph 1-21.

However, the multi-alarm indication receiver module contains no fluid level meter. It contalns-circuits that permit it to respond to the detection of a high fluid level or low fluid level alarm by up to six alarm circuits in receiver modules. Response to alarm detection is provided by the lighting of a front panel lamp associated with the alarm circuits and the sound ing of a sonalert audible alarm in the multi-alarm in dication receiver module. A toggle switch for the silencing of the sonalert alarm and a fuse are also contained on the front panel. Electrical connection to the unit is made at the bottom of the box enclosure and includes power input, signal input and remote audible output.

1-32. The alarm lamps on the front panel of the multi-alarm indication receiver module are parts of lamp-switch assemblies that have a press-to-test feature. When the lens of the lamp is pressed to wards the panel, the switch portion of the assembly is actuated and applies a test signal to the lamp. A properly operating lamp lights while the lens is held depressed.

1-33. Alarm J-Box. The alarm J-box (figure 1-10) is an electrical connection box that contains audible (sonalert) and visual (lamp) alarm indicators and a toggle switch that silences the audible alarm. Elec trical connection to the alarm J-box is made to an internal terminal board strip via two stuffing tubes mounted on the circumference of the J-box.

1-34. Alarm Bells. Two alarm bells (figure 1-10) are available for use with a TLI system, a 3-inch and an 8-inch bell. These bells are standard Navy alarm bells that are installed on a bulkhead using mounting holes in a metal strip at the rear of the alarm bells.

1-35. Portable Secondary Meter and Connection Box Combination. Portable secondary meter and connec tion box combinations are available for the observa tion of fluid level indications at remote locations aboard ship. Secondary connection boxes (figure 1-

10) used in these combinations are distributed at appropriate locations. The secondary connection boxes have a cover that incorporates a magnet. This maKnet actuates a reed switch within the secondary connection box when the cover is closed. With the reed switch actuated, a resistor is switched in place to act as a dummy load for a meter circuit in a prima ry receiver module or receiver panel. When the cover is opened, the resistor is removed from the circuit and a portable secondary meter is connected to an electrical connector in the secondary J-box to form a series circuit with the primary meter circuit.

1-36. The portable secondary meter is a box-like structure with a carrying strap. When the front cover of the luiit is opened, access is provided to a fluid-level meter and storage space containing a cable that connects to a secondary connection box. When the electrical connector on the cable is plugged into the mating secondary J-box electrical connector, the meter deflects to indicate the same readout as the primary receiver module or receiver panel meter to which the secondary connection box is wired.

1-37. INSTALLATION ACCESSORIES. A variety of installation accessories are available to aid and ac complish the mounting and wiring of the components of a TLI system. (See figure 1-11.) Installation accessories are as follows:

a. Weld-Mounting Bracket Assemblies. Three types of mounting bracket assemblies are available for the weld-mounting of bracket-mounted transmit ters. Mounting bracket assemblies, Part No. 36407 and 36413, are stainless steel and carbon steel mounting brackets, respectively, that are welded to the bulkhead of the fluid tank in which a transmitter is to be installed. These mounting bracket assem blies are drilled through to accommodate mounting bolts, that are secured to the brackets on transmit ters with lockwashers, flat washers and nuts. Mount ing bracket assembly, Part No. 36409 is similar to Parts No. 36407 and 36413, but has tapped holes.

The tapped holes permit mounting bolts to be secured in the bracket for those installations in which there is not enough room for nuts, flat washers and lock-washers on the outside of the bracket.

b. Sounding Tube Mounting Bracket Assembly.

Sounding tube mounting bracket assemblies, Part No.

31795 and 32445, are used to mount bracket-mounted transmitters to 1-1/2-inch and 2-inch sounding tubes in fluid tanks, respectively. Both sounding tube mounting bracket assembly types consist of an angle bracket, a U-bolt sized to accommodate the associ ated sounding tube diameter, and holes that line up with the holes on transmitter brackets.

c. Ladder Mounting Bracket Assembly. Lad der mounting bracket assembly, Part No. 32579 is similar to the sounding tube mounting bracket assem bly described above. However, a C-bolt is used in place of the U-bolts to permit the ladder mounting bracket assembly to be secured to a fluid tank ladder.

d. Standpipe Mounting. Standpipe mounting, Part No. 33000, is comprised of a 5-inch flange con nected to a 5-inch pipe section. The unit is welded in a hole drilled in the top of a fluid tank to provide a supporting surface for flange- mounted transmitters.
