MA-4 Positive Displacement > Maintenance > Pulse Output Device (POD5)

The Liquid Controls Pulse Output Device (POD) converts the rotary motion of the Positive Displacement Meter into electronic pulses, making it possible to interface the meter to electronic monitoring and control equipment. The POD5 was specifically designed to interface with the MA4 meter and the SCAMP A™ electronics.

The POD5 mounts directly to the front cover of the MA-4 meter. The motion of the meter blocking rotor is magnetically coupled through a stainless steel wall into the electronics compartment of the POD5. This eliminates any dynamic seal and isolates the electronics from the process fluid in the meter.

Inside the POD5 electronics compartment, an optical shaft encoder converts the rotary motion into a high resolution, two-channel quadrature square wave. Both outputs switch from 5 volts in the ON state to zero volts in the OFF state.

The POD5 electronics compartment also serves as a conduit junction box. The POD5 has an O-Ring sealed, threaded cover. The standard wire entrance is a 1/2-14 NPT female hub, which accepts threaded conduit or a cable gland. A plug-in connector on the encoder facilitates wiring of the unit. With the wiring entrance sealed and the cover in place, the housing is ENCLOSURE TYPE NEMA 4X, weatherproof rated. In addition, the housing is CENELEC rated flameproof, and UL and Canadian-UL explosion-proof rated when properly installed with approved conduit.

Installation

The POD5 comes factory installed on the meter ready for wiring with the conduit orientation in the up position.

The hub can be oriented in one of four possible directions; facing up, down, left, or right. If a different orientation is necessary, remove the two mounting screws and pull the POD5 from the front cover. Remove the POD5 O-ring from the cover.

Follow these steps:

1.After determining the orientation of the conduit hub, determine which two of the four mounting screw holes will be used to fasten the POD5 to the front of the meter cover. It is suggested that the mounting screws be driven into these holes first to “pre-tap” the threads in the meter cover. This will make it easier to thread the screws when the POD5 is in place.

2.Position the O-ring on the bottom of the POD5.

3.Align the fork driver to the drive mechanism inside the meter and guide the POD5 into the opening in the meter cover. When the driver is properly aligned the POD5 will go in until its mounting flange abuts the meter cover.

4.Rotate the POD5 to the desired orientation and thread in the mounting screws finger tight. Using a 5/16-inch box-end wrench, tighten the screws to the appropriate torque as specified in the Torque Chart.

Wiring

Wiring into the POD5 must enter through its conduit hub. For explosion-proof rated installations (Class I, Div. 1) the wiring must be enclosed in rigid conduit that is rated for explosion-proof installation. The conduit must be engaged five (5) full threads into the female hub on the POD5 to meet explosion-proof standards. When a Division 2 installation is called for, either rigid conduit, flexible conduit such as LiquidTight (or no conduit) can be used. When no conduit is used, the instrument cable must be brought into the conduit hub using a cable gland to seal the wiring entrance to maintain the ENCLOSURE TYPE 4X rating. Irrespective of the type of conduit/cable gland used, thread sealant should be applied to prevent moisture from getting into the POD5 electrical housing.

Removing the cover of the POD5 will expose the plug-in connector and ground screw.

Service Information

Due to the simplicity of the POD5, there are few things that can go wrong with the device. However, as with all electronic devices, failures can occur making it necessary to replace failed part(s). There are only three functional spare parts for the POD5: (a) the hub/magnet assembly-North Poles, (b) hub/magnet assembly-South Poles, and (c) the encoder assembly. The South Pole hub/magnet assembly operates inside the flowmeter and, therefore, is made wet by the process fluid. Due to its materials of construction, this assembly is unlikely to fail. In the event that it does fail, the POD5 has to be removed from the meter front cover to access the driver/ lower magnet assembly.

Remove the POD5 from the meter by removing the two hex head mounting screws and pulling out the POD5.

Remove the two allen-head set screws using a 1/16-inch hex driver and pull on the driver tang to extract the driver / lower magnet assembly. Disassemble the hub/magnet assembly from the drive shaft and attach the new hub / magnet assembly in its place. Reassemble the unit.

It is more likely that if a failure of the POD5 occurs, it can be repaired by replacing the encoder assembly. Simply turn off the power to the unit, open the cover, disconnect the electrical connector, loosen the mounting screws and pull the encoder assembly out. Remove the hub/magnet assembly from the old encoder shaft. Reassemble the new encoder assembly.

Use correct hub/magnet assemblies

It is important to use the correct hub/magnet assemblies to maintain the magnetic couple. Use of two North Pole or two South Pole assemblies will not allow the driver to function properly.

Trucks of the Yaroslavl automobile plant Ya-5

Yaroslavl five-ton truck

photo from the archives of OAO YaMZ, Dmitry Dashko and the author

Despite the fact that these cars appeared a decade and a half before the end of the “carburetor” history of YaAZ, in terms of their performance, they became the pinnacle of all pre-war serial production of the enterprise, and in addition, they served as the basis for many modifications. Today Ya-5 trucks are celebrating their 80th anniversary.

They came across on the roads even after the war, pretty beaten up, patched up, but quite cheerfully howling with their rear axles with spur gears. Drivers loved these cars much more than the rest of the base pre-war “Yaroslavl”. It was they who in everyday life began to be called “five-tons”.

Trucks of the Yaroslavl Automobile Plant, produced since 1925, were based on the American White-TAD and Packard of the First World War, the design of which was largely revised and modernized. The first-born Ya-3 received more modern components and assemblies, external elements (in particular, the cabin), disk wheels and pneumatic tires. However, the weak engine (35 hp) remained the Achilles’ heel of the Yaroslavl three-ton. A temporary solution was found in the purchase of imported power units. C 19In 1928, they began to mass-produce 4-ton Ya-4s with 54-horsepower Mercedes engines, updated cabs and plumage, and a year later they were replaced by 5-ton Ya-5s with American engines.

Five-ton structure

Hercules-YXC-B in-line 6-cylinder engines with a displacement of 7022 cm ³ and a power of 93.5 hp began to arrive in Yaroslavl by the middle of 1929. The engines came with a carburetor, magneto, regulator, fan assembly, air filter, muffler and all control levers. Complete with engines, Brown-Lipe multi-plate clutches and Brown-Lipe-554 4-speed gearboxes were purchased.

To install these power units, the base Yaroslavl model was again upgraded: the truck received a completely enclosed cab of a simple and technological form, glazed doors, electric lighting and a starter, as well as an improved steering mechanism. Significantly increased power made it possible to reduce the gear ratio of the main gear to 8.0. The wheelbase of 4.2 m and overall dimensions (6.5×2.28×2.6 m) are inherited from the Ya-4.

For all subsequent production models up to 19On the 42nd, the resulting Ya-5 model became the base model. The chassis underwent only minor changes, and the difference was only in the installed engines. But only in Ya-5, the engine power corresponded to the chassis used, on all subsequent models, as well as on the previous ones, its deficiency was noticeably affected.

Frame Ya-5 was assembled on rivets from sections of standard channels No. 16 160 mm high with shelves 65 mm wide (spars) and channels No. 10 100 mm high (crossbars). The radiator was not used tubular, as on most machines, but honeycomb, the manufacture of which took 50 kg of brass, which was then in short supply. The Bosch-Devaunder vacuum booster, located on the left side member, was connected to the engine intake pipe, where the vacuum ensured the movement of the piston in the brake cylinder and reduced the effort on the brake pedal. The car had two cardan shafts: the first horizontal, open; the second inclined passed in a welded conical tube, which transferred the pushing and braking forces of the rear axle to the frame. An oil pocket was installed on the left side member for lubricating the cardan joint and the ball joint of the cardan pipe, connected to them with a rubber hose.

The Ya-5 cabin had a wooden frame. The front and side walls were sheathed with sheet steel, and the back with pine planks. The roof was covered with plywood and pasted over with a cloth on mastic. The left half of the windshield (triplex type) was hinged in a metal frame, fixed with winglets and sectors in any position up to 45 °. Handicraft power windows in almost square door windows, like all pre-war YaGs, did not work well. The windows in the rear wall of the cabin were protected by three metal bars. For ventilation, there were ventilation hatches on both sides of the dashboard.

The wooden footboards were sheathed with sheet steel along the edges. The wings were fixed on the front brackets of the footrests, and in the middle they were supported by brackets made of steel angle. Almost all production Ya-5s had a short front bumper, and the front wings were not attached to it. For access to the engine, the composite sides of the hood were raised and traditionally folded at the top, and if necessary, they could be completely removed. For additional cooling of the engine, 15 vertical louvres were made in them, and on the upper halves there were lifting covers, which, as a rule, were in the raised position during operation. Since the engine was located quite low, the axis of its fan lay at a third of the height of the radiator, so the fan pulled air only through half of its surface.

Despite the large diameter of the steering wheel (522 mm), the effort had to be made so much that drivers sometimes suffered from chronic overexertion of the hands. In 1932, a new, lighter steering was mastered (of the Ross 302 type), but it was only put into production three years later. Of course, during the operation of the I-5, they tried to replace this unit with a modernized one.

It must be emphasized that the supply of spare parts was extremely unsatisfactory at that time, and the situation with foreign components was even worse. Therefore, in the event of the failure of the American Ya-5 engine, they most often continued to serve with the ZIS-5 or AMO-3 engines.

Unfortunately, the import of American Hercules-YXC-B engines was discontinued in 1931, and most of the remaining sets were reserved for the three-axle YAG-10 and Y-6 chassis, so the production of the Ya-5, which proved itself so well, had to be stopped. More precisely, the chassis continued to be produced almost unchanged, but the power unit was forced to install only a 60-horsepower AMO-3 engine, with which the truck (under the symbol YaG-3) even with the gear ratio of the GP increased to 10.9, according to the drivers, “barely dragged myself.”

In total, from 1929 to 1934, 2284 Ya-5 trucks were produced: in 1929 – 132; in 1930 – 754; in 1931 – 1004; in 1932 – 346; in 1933 – 47 and in 1934 – the only, last.

Special equipment and modifications

Most of the serial Ya-5s were equipped with standard onboard platforms, but there were also special vehicles on its chassis. For example, in 1931, at a mechanical repair plant in Detskoye Selo (now Pushkin, Leningrad Region), they began designing the first Soviet AG-1 asphalt distributor. Early 1932 AG-1, developed by engineer N. I. Obukhov, was manufactured on the chassis of the Ya-5 truck with the AMO-3 engine that was already in operation.

In 1932, at the Yaroslavl Automobile Plant, according to the project of engineer M.A. Olimpiyev, a vacuum tank was built to replace the horse-drawn convoy for cleaning cesspools. The cistern, 4 m long, internally divided by partitions into 3 parts, was made by riveting from boiler iron and designed for 5,000 liters.

In 1933-1934 on the Y-5 chassis, Dormashobedinenie and the Onega plant manufactured snowplows, some enterprises produced tanks for fuel, milk, etc.

The first in a series of Ya-5 modifications can be called the Ya-6 long-wheelbase (5280 mm) bus chassis designed almost immediately, on which, in turn, the Ya-8 truck was built in 1931, equipped with a 102-horsepower Continental-21R engine and a low elongated side platform*.

There was a prototype Ya-5 of standard dimensions, the frame of which was made exclusively by welding according to the project of the Orgmetal welding office.

In March 1932, a Mercedes-Benz OM-5 diesel engine with a capacity of 70 hp was installed on the Ya-5 chassis.** In fact, it was the first diesel truck of domestic production. To install a diesel engine, the front ends of the frame spars and the hood were lengthened, the radiator and buffer with headlights were pushed forward, the chassis was fully adapted to the engine. This experimental work was carried out in case of a possible purchase of industrial batches of imported diesel engines and proved the full suitability of the Ya-5 chassis for working with a diesel engine, as well as the ability of factory specialists to cope with the conversion of trucks to diesel engines.

Somewhat later, in 1933, for the All-Union diesel motor rally Moscow-Tiflis-Moscow, imported diesel engines Deutz, Ganz, MAN, Saurer, Lilloise (Peugeot subsidiary in Lille) and Leyland. And although the run took place only in 1934, in fact, for 26 of its participants, slightly improved Ya-5 chassis were used. The same can be said about the first truck with a domestic diesel engine “Koju” (Koba Dzhugashvili), two copies of which were made in the fall of 1933 (they also participated in the run). Factory sources designate its chassis as Ya-5. Thus, all of the listed models can also quite rightly be considered varieties of the five-ton.

In 1933, the first and only Yaroslavl gas generating vehicle was built on the Ya-5 chassis. Its installation consisted of two twin gas generators of the GAZ type, mounted on the sides of the cab (for which its design had to be changed and the seat narrowed) and connected to each other by a cleaner-cooler located under the body. A special main cleaner, consisting of copper tubes with fins, with a collector at the top and two sediment pockets at the bottom, for the first time in the USSR was mounted in front of the radiator, repeating its shape. The engine had a modified head with a compression ratio of 8.2. There was no carburetor on the car, and its place was occupied by a gas mixer, which had a float chamber and a starting jet for starting the engine on gasoline, but constant operation on liquid fuel was impossible.

In December 1933, the gas generator Ya-5 (the machine did not receive its own index) with a load of 3730 kg made the first runs along the Mozhaisk highway of the capital with a total length of 89 km. During the 5-hour non-stop operation, the car showed average speeds of 20.2 km / h in the city and 33.4 km / h on the highway and a cruising range of 100–110 km at one refueling of bunkers. In March 1934, a control run of 116 km was organized, covered in 6 hours and 38 minutes. Charcoal consumption was 71.3 kg per 100 km, and the average truck speed was 25.9km / h, which is only 2.3 km / h less than the average speed on gasoline. But the cost of transportation in terms of reduced by about half. In May 1934, a gas generator truck ran along the route Moscow-Serpukhov, and then Moscow-Leningrad-Moscow, where the car showed good performance. However, shortcomings were also revealed: poor-quality primary cleaning in the purifier-cooler, high resistance of the cooler (small diameter of the tubes), etc. The main reason for refusing further work on gas-generating “Yaroslavl” was the lack of “Hercules” and the inevitable decrease in power when switching to gas, which, for AMO engines, already low-power, made the car inoperable.

And finally, in 1934, Ya-5 became the basis for the first (and also the only) Yaroslavl half-tracked truck YaSP, equipped with the French tracked propulsion system Somua. The YSP had overall dimensions of 5060x2400x2550 mm, a curb weight of 6 tons, a load capacity of 2 tons (plus a 4-ton trailer) and an average fuel consumption of 90 l / 100 km. The reasons for refusing further work were similar.

Buses

From 1929 to 1933, the Yaroslavl Automobile Plant also mass-produced Ya-5 chassis with a base extended by 580 mm (received the Ya-6 index) for installing passenger bus bodies on them.

It was not difficult to increase the length of the frame spars from a rolled channel. Accordingly, they lengthened the driveline and rear brake drive rods. The plant did not then have either the equipment or specialists for the manufacture of a rather labor-intensive bus body, therefore it produced only the chassis. Bodies for them for 27–35 seats were built by the Mostrans Auto Body Repair Plant (later Aremkuz), Leningrad ArZ No. 2 ATUL, Soyuztrans auto repair shops in Rostov-on-Don, car body shops in Kharkov, Tiflis (Zakavtopromtorg) and other cities. The lattice frame of these bodies was assembled from wooden bars of different sections and sheathed on the outside with a steel sheet, and in some places with plywood. The roof was covered with leatherette, the upholstery was made of plywood, planks of the “lining” type and leather substitutes. Since the Ya-6 frame did not have bulges above the axles, the floor in the bus body was located quite high.

Buses on Ya-6 chassis became the first domestic serial city buses. The first two I-6s, manufactured at the end of 1929, were sent to the capital and soon entered the line with Aremkuz bodies. And two years later, out of 237 buses in the capital, 50 were on the Ya-6 chassis. In Leningrad and in 1935, they accounted for 30% of the entire bus fleet, and more on suburban lines. Some copies, having served their time in large cities, then went beyond the Urals and to Central Asia.

Naturally, the buses based on Ya-6, which did not have their own index in the final version, were strikingly different from each other: Leningrad from Moscow, Rostov from Leningrad, etc. It is interesting that in 19On the 30th, the Rostov auto repair trust Soyuztrans produced, along with 14 closed ones, 16 open buses on the Ya-6 chassis.

Although the Ya-6 foot brake was equipped with a vacuum booster, it was still ineffective. They tried to solve this problem in February 1932, when for the first time in the USSR, a disc transmission brake installed on one of the Ya-6s was manufactured according to the NATI project. It was allowed to use it only as a parking lot or for an emergency stop. The brake pedal on the Ya-6 acted on the rear wheels, and the handbrake lever was connected to the central brake on the cardan shaft. But this design did not go into series due to the complexity of manufacturing and balancing.

From 1929 to 1933, only 364 Y-6 units were produced: in 1929 – 12 units, in 1930 – 95; in 1931 – 109; in 1932 – 148. There could have been more, but the production of Ya-6 was forced to be curtailed due to the lack of Hercules-YXC-B engines. Compromise version of the 60 hp engine. for buses with a curb weight of about 5.5 tons was unacceptable. An attempt to continue the production of a long-wheelbase bus chassis under the YA-3 index with a domestic engine did not bring success. On the other hand, the previously manufactured Ya-6, and after several years, having undergone a major overhaul, became the basis for more modern buses of already streamlined shapes.

Unfortunately, over the past decades, all cars of this brand and their modifications have completely disappeared into oblivion. Not a single hero of the day has survived to this day.

* Experienced Ya-8 is often confused with Ya-7 and Ya-7-D developed by NATI (more correctly, Ya-NATI-7D). The experimental Ya-NATI family, which included the long-base version of the Ya-NATI-8 (remaining “on paper”), was structurally significantly different from the Yaroslavl machines, while the factory Ya-8, which, by the way, appeared much earlier than the Ya-NATI, was just a longer and more powerful version of the I-5.

** Most likely, this is where the confusion arose with the power of Mercedes engines, which were installed on Yaroslavl trucks. In almost all publications of the 1930s for the Ya-4, it was declared as 54 hp. However, starting from post-war sources, already 70 hp appears everywhere. Apparently, someone simply confused the carbureted 54-horsepower Mercedes, 137 of which were purchased in 1928 for the Ya-4 with the “piece” diesel Mercedes-Benz-OM-5, experimentally installed on one of the Ya-5s in the spring of 1932
