SAFETY PRECAUTIONS. stress the importance of To e mploying proper safety techniques while performing maintenance procedures on the e quipment involved, the user of this manual is directed t o thoroughly familiarize hims el f with the s afety p recautions described in Chapter 4, paragraph 4-4. ( This manual 1-2. INTRODUCTION. provides information and instructions for installation, operation, and maintenance of Transmitter Distributor (TD) Sets Model 28 (figure 1-1). Maintenance information provided for the TD sets includes instructions for testing, performing preventive maintenance and adjustments, �roubleshooting, and repairing. A parts list is also included. 1-3. EQUIPMENT DESCR IPTION. The TD S et Model 28 is an electromechanical device used to send code combinations perforated in tape and translate these combinations into electrical impulses in the form of a Baudot code signal. a. When General. connected by radio or wire telegraph channel s with teletype equipment in other ships or statiops, the TD set originates signal transmission. It is a send only mechanism not equipped to sense the electrical characteristics of incoming messages on the signal line. ( (1) Transmission of signals from the TD set to a distant station is accomplished electrically by u se of a five unit, stop-start permutation code. Depending on the trans mitting cam sleeve used, the transmission pattern may be either 7.00 units or 7.42 u nits. The nominal operating speed for 7.42 is 368 operations per minute (opm) corresponding to 60 words per minute (wpm). By changing gears which are available as optional components, the operating s peeds can be increased to 460 opm (75 wpm) or 600 opm (100 wpm). (2) E ach TD s et i s equipped with a control s witc h for turning off the set without disconnecting it from the signal circuit. M ost sets are equipped with an automatic line shunting switch which closes the loo p signal circuit when the TD is removed from its base. (3} Each TD set is provided with a three-position switch by m eans of which the set is made to re ad t ape, stop reading tape, or free the feed wheel to permit feeding t ape under t he t ape wheel into the tape guide without raising the lid. (4) Power is br ought into each set to the motor or motor unit through a po wer switch. The motor or motor unit drives the TD unit through an inter mediate gear assembly. (5} The message signals are read from a t ape which is either f ully perforated or chadless and then transmitted by either a 0.020 ampere or a 0.060 ampere de line current to external receivers. b. High-Level and L ow Level. This manu al covers both 1-1 NAVELEX 0967-LP-615-3010 h igh-level and low-level co nfigurations of TD sets. H igh-level sets a re used in applications wher ein radio f requen cy interference (FFI) does not present a problem. L ow-level sets have RFI suppressi on incorporated. One of the rfi suppre ssion featur es i s the use of a low-level signaling code from which t he term low-level is derived. The low-level signaling code is the they are tr anslated into electrical impulses and transmitted sequentially to the signal line. The TD unit u sed in these sets may be equipped with code reading contacts fo r multiwire (simultaneous) output as an optional feature. By use of these contac ts, which ar e actuated by the individual transfer levers, the tape message is electrically trans mitted by parallel wires to +6 volts (mark) a nd -6 volts (space) polar code levels versus that of the 0.060 ampere (mark) and 0.0 ampere (space) neutral code levels used in the high level sets. High-level TD equipment is desc ribed in pa ragraph 1-3.1 a nd low-level TD equipment is described in paragraph 1-3.2. external receiv ers for monitor ing purposes or page copy. This is done simultaneou sly with transmi ssion through the single contact signa l generato r. 1-3.1 EQUIPMENT DESCRIPTION (HIGH-LEVEL) A typical TD set Model 28 consists of a base, TD un it, a motor or moto r unit, and a cover. TD sets may be either single contact or multicontact sets. Single contact sets may be either regular size or m iniaturized (figures 1-2 a nd 1-3) . The multicantact s et (figure 1-U) is regular size only. The regula r size set (figure 1- 5) has a regular size only. The miniat ure set (figure 1-6) has a smaller base a n d cover designed for use with a small motor. • Single contact Sets. a. The TD units used in the two single contact sets (regular size, and miniatu re size) are identical as to function and configuration. T he single contact mechanism is actuated once for each lev el of the code combination by a distributing cam sleeve. The code combinations sensed in the message tape are mechanically transfe rred to the single contact s ignal genera tor wher e 1-2 Single Contact b. The regular Regul ar Size Set. size single contact TD set (figure 1-5) co nsists of a base, a motor unit, TD unit and a cover . The base extends a full length of the set, and is equipped with an intermediate gear assembly and vibrati on mounts. It serves as a mounting for a TD unit, and a standard size Model 28 motor unit which may be either a 115-volt, Go Hertz, ac synchronous, or a 115volt, 60-Hertz, series governed. A slip-over type cover encloses the motor unit and that porti on of the base not occupied by the TD mit. A U-shaped front panel covers three sides of the TD unit. This panel snaps into It is easily removed position. for access to the mechanism of the TO unit. '� ) '' Single Contact c. The Miniaturized Set. miniaturized set has been so characterized b ecause of its compactness (figure 1-6). The smallness in si ze is accomplished through design of the base and cover, and b y use of a compact 23 millihorsepower synchronous motor. This set performs the sa me function as :. ',�
