SEC':':;'.ON I GE~ERAL :Z:)lFORMATION 1.1 INTRODUCTION This :nanual describes the operation, i~stallation and maintenance of the DualFrequency TRU-II Code Reset Module, US&S part no. N4512C6-0301. The module is desig~ed for use with a TRU-II Track Resonant Unit (re:er to service manual SM6236) when the latter is applied in code overlay applications. Ween a track circuit shunt is rel~ased in a TRU-II cede overlay arrangement, the module provides the release of the "V" (frequency control relay), allowing t~e TRU-II to reset with steady energy track feed. The module is a plug-in package designed for mounting on a standard relay rack configuration using a special mounting plate. The Dual Frequency TRU-II Code Reset Module differs from the earlier Code Reset Module (part number N451206-02XX) in the following respects: 1.2 A. Operates at a second carrier frequency of 250 Hz B. Provides reset capability for additional standard code rates of 270 and 420 C. Does not function as a vital device (refer to section 3.1) D.

FUNCTIONAL DESCRIPTION (See :igure 3-1) 3.1 GE~RAL (See Figure 3-1) The Dual-Frequency TRU-Z:! Code Reset Module is designed to take its signal input from the tracks in parallel with the TRU-!I Track Resonant Unit. The local input is only used for internal power. Track relay no. 1 back contact is connected in series with the reset module input in order to disconnect the source during steady energy track conditions. When a train shunts the nor:nally steady energy track circuit, the no. 2 track :relay back contact connects the Bl2 scu:rce to the "V" relay by way of the RRl? back contact and traffic control circuits. The "V" relay connects the source (100 Hz and 250 Hz coded energy) to the track input. When the train vacates the track circuit, the track system must be reset to the steady energy mode. The reset is accomplished by the reset module which, aft.er several 100 Hz or 91.67 Hz code cycles, picks up the RRP relay. The "V" relay stick circuit is released and the source is switched back to steady energy, permitting the TRU-!I to pick up. NOTE The Dual-Frequency TRU-II Code Reset Module is not considered "vital" since resett.!.ng code to steady energy is not a vital function. The ':'RU-I! Track Resonant Unit provides the required steady.energy pick-up. 3.2 DETAILED (See Figure 3-2) The Dual-Frequency TRU-II Code Reset Module accepts 91.67 and 100 Hz input signals from the W-400 track t:ransfor.r~r at pins 6 and 7. The nominal input signal level is about lOV ac RMS. A series-tuned fi~ter, consisting of C4 and L23 is connected in series with the input to transformer T2. A second series-tuned circuit, consisti.~g of C3 and Ll, is connected to the secondary of transformer T2 in series with the PC board lead. Under minimum i~put signal of 9V ac RMS, transformer T2 operates as a normal transformer device. When the input inc:reases above this minimum level, T2 begins to satu:rate, thus limiting the amplitude of the signal. The C3/Ll filter tunes out the harmont~e created by the saturable transformer action. In addi::ion to i::=:,viding ampli::.ude lim.!.ting fo= i:1-band signals (91. 67 and 100 Hz), T2 also provides amplitude limiting for 25 H= and 60 Hz propulsion =requenc.!.es. The a.~pli~ude limiting level at 60 Hz is about 60% of the 100 Hz limiting level, while the limiting leve: at 25 H= is about 25% of the 100 Hz li."Iliting level. The 250 Hz s.!.gnal frecr~ency is also limited by the combination of ::lte:rs and saturable transfor:r.er. The ~wo series-tuned ci==ui~s are scaggertuned to ?rovide a wide bandwidth for d~al f=eC"~e:1cv and high code rate ope:ration. 6237 ..·'.l., :=>. ------~~---------~ I I I I I I I I --------1 I I I I I I I I I I I I I .:t ______ _--------------- -------- ....-~.

DC output pulses charge capacitor C2 (4,700 uF) through steering diode OS. Resistor R4 (27K) provides a high impedance discharge path for C2. The output of the full-wave rectifier also charge capacitor Cl (47 uF) via the back contact of mercurf-wetted reed relay Kl. Capacitor Cl has a series-connected 685 chm relay coil, resistor R2 and parallel combination of RS ar.d R6 as a fi~ed, relatively fast discharge path. When Sl.67 or 100 Hz code pulses are applied, several seconds are required before relay K: can pick up, due to the charge time of capacitor C2. When Kl picks up, Cl provides the relay coil feed over the ccntact t=ansfer time. When the Kl front contact is made, the relay feed circuit has steering diode 07 and an additional resistor (Rl) connected in series with its coil. This action increases the reset module's input impedance to about lK oh.~. The Kl relay remains energized since the release voltage level is considerably below the pick-up voltage. Relay :K2 is a power relay repeater cf Kl. It is powered by the local llSV ac, 91.67 or 100 Hz input to PC board terminals 5 and 6. Transformer Tl, in conjunction with diodes 08 and 09, make up and unfiltered l2v de power source for the relay. Resistor R3 is a 680 ohm device. The output f=om this de supply is fed through the front contact of Kl to the K2 repeate= relay. Diode 06 is a relay coil snub. PC boa=d resistors Rl and R2 are shown as TBD (to be determined) for adjustment purposes due to variations in manufacturing specifications for Kl. Ther.nistor RS and parallel resistor R6 are for relay temperature compensation. 3i; ~ @) BLK. BRN, z C4 0 h] I'· <Q I~ rt (I) nt z (ii; L2 SUPPL! ED WITII L2 r r I ~.) 6 OJ w o. 0 )> 0 BLK.

A module suspected of being defective should be replaced with one known to be in working order. If a module is found to be defective, it should be given t~e shop troubleshooting and repair procedures in section 4.3, or returned to us~s for repair or replacement. Call l-800-652-7276 for factory service information. No attempt should be made to repair the module in the field. EXTREME ~ SHOULD BE E.."<ERCISED DURING "POWER ON" TESTS OF THE DUAL-FREQUENCY TRU-II CODE RESET MODULE.
