The UTS-0660 supplied complete with 2.5 kg (5.5 lb) and Ø50.8 mm circular faced rammer, 4.5 kg (10 lb) pie-shaped rammer, one for each Ø4" and Ø6" moulds. This device conduct standard or modified compaction tests with

5.5 lb. rammer with 12” (305 mm) height of drop or 10 lb. rammer with 18” (457 mm) drop. Rammers can easily be replaced from the front side of the compactor.

The selected rammer having the required weight and diameter is picked up by a chain drive lift mechanism. It has a cam system for accurate height release and made of hard-wearing material for trouble free long- life.

The total weight of the rammer is concentrated at the foot in order to provide a free-fall action.

Machine stops automatically after preset number of blows per compaction is completed. The number of blows per layer complying related standards can be selected through the digital control unit at the beginning of the compaction operation. Compaction mould is mounted on the round base; the circular base indexes automatically with each blow to ensure uniform sample compaction. A pie-shaped compactor foot is used with 6” (152 mm) dia. moulds to completely cover the surface of the sample.

All moving parts are shielded by closing the doors while the machine is running. A micro switch stops the operation if the doors are open, which helps to do maintenance easily.

It is also compatible with the requirements of CE norms about electrical equipment, machine security regulation, electromagnetic compatibility regulation and some other standard judgments.

Figure 1 shows a technical drawing of the device. You can see the dimensions of the device on this drawing. Observe these dimensions before installing the device (Figure 1).

UTS-0660-N consists of a digital control unit, front safety doors, door locks, door switch, optical sensor, rammer, rammer movement mechanism, rammer lifting mechanism rod, rammer catch /release and position lock tongue, rammer guide carrying frame, chain, optic sensor activator plate, and rotational base platen. See Figure 2 for the locations of the all parts of the machine.

Figure 2: Parts of the Machine

Front Safety Doors: When one of the two safety doors is opened, the door safety switch cut out the drive motor. This prevents the operator to access the rammer drop area and thus possible injuries.

Door Locks: There are two door locks. After door is closed to remain the door in closed position, those two door locks must be locked.

WARNING: If the door switch breaks down or gets damaged as a result of any negativity, notify the UTEST technical team immediately.

Optical Sensor: It sends the signals to the digital counter when the small metallic plate fitted to the chain comes to the closest distance with optic sensor in order to count number of blow one by one.

NOTE: The maximum displacement between chain and optic sensor must be 8 mm.

Table 1-UTS-0660-N Parts

Door Switch: It acts like the pause key for safety reasons whenever the doors are opened while the device runs.

Rammer Movement Mechanism: This mechanism provides lifting the rammer to the top position of the chain and lets the rammer drop along with guide rods on the surface of sample mould while compaction is operated on 4” or 6” moulds. Base plate rotates in relation with rammer motion. Base plate does not move in radial direction, only rotates. For compensation, a different pie shape rammer is used for 6-inch mould. After each blow, the rammer is raised to its initial height by this mechanism. Before conducting a test, the rammer position should be adjusted manually. The position point should be at the position, at which the rammer will be up and just about to drop.

Chain: The chain helps the mechanism connected to itself to catch and release the rammer. It rotates in clockwise direction.

Optic Sensor Activator Plate: This metallic plate fitted to the chain ensures signal to be sent to the digital counter by passing through the front of the optical sensor. Thus, digital counter gets able to count rammer blow number.

Rammer Guide Bars: They are for guiding the rammer. Rammer is lifted and dropped through those 3 guides.

Rammer Lifting Mechanism Rod: The mechanism providing the rammer to be catches and released moves vertically through this rod.

Rammer Catch /Release and Position Lock Tongue: This tongue catches and drops the rammer from the selected height. It also holds the rammer in locking position at its initial position after compression process. Thus, it prevents accidental dropping of the rammer while positioning a mould.

Rammer Guide Carrying Frame: It ensures the position of the rammer on horizontal axis to blow inner and the outer part of the mould. The rammer does not change its position, mould plate moves.

Rammer: There are two separate rammers for 4 and 6 inch moulds. Pie shape one is for 6 inch moulds. Round one is for 4 inch moulds. They are not interchangeable use-wise.

Pie Shape RammerRound Shape Rammer

The rammer is manufactured into two concentric parts because rammer weights must be different mentioned in the related standards. The outer part is used for low energy compactions, and the combined inner and outer parts are screwed together for high energy compactions.

Rotating Base Platen: The rotation base platen is designed to give the best homogenous blow pattern depending on the size of the moulds. Just after the rammer leaves the sample and the table rotates the mould in equal steps and stay stable until next blow. There are 4 screw holes on the platen; one pair for 4-inch mould and another pair is for 6-inch mould connection.

Make sure that the room in which the device is going to be placed have a proper mains supply which is in compliance with the machines specifications, and enough number of plugs for the connection of the device, PC/laptop, etc.

Check the voltage (V), ampere (A), frequency (Hz), phase (Ph), and power

(W) of the UTS-0660-N in Table 1.

Table 2-UTS-0660-N Electrical Connection Properties

Main electricity line must be free from instabilities and repetitive power cuts for both the extended life of the device and the continuity of testing. Therefore, make sure that the mains supply is well grounded. If the power cuts are frequent or the grounding is not well enough, the use of an uninterruptible power supply (UPS) is recommended.

Make sure that the device is placed in a clean and dry surrounding. Direct contact of the device with the sunlight should be avoided. A conditioned room for example, will comply the above conditions and will result in best operational performance and measurement results. Device should be well accessible from the front and the sides for connections, testing and maintenance.

In order to prevent inaccurate test results, the ground should be rigid enough to minimize vibrations or shocks. If there are any other testing equipment or a source that creates vibrations on the floor, UTS-0660-N should be placed maximum possible distance to that source. Surface of the

ground should be horizontal and smooth enough so that the horizontal and vertical alignments of the device are not shifted.

NOTE: If remote assistance will be required from the UTEST Technical Service Department, the room should have an internet access.

NOTE: The power cord is coded as follows: Brown wire L Live or Power, Blue wire N Neutral, Green/Yellow wire E Earth or Ground.

Place the device on its foundation which must be level and stable also near an appropriate power source. Leave about 500 mm all around the machine so that the guard doors can be freely opened to allow for the placing/removing of the moulds and leave enough space at the sides of the unit so as to you canclean the device, maintain the machine and access the back of the unit. Since the rammer is free falling, the machine must be perfectly aligned vertically after installation. It is recommended the slope of

floor on which the machine is installed is less than 5 degrees. A spirit level can be used to measure verticality and perfect verticality can be adjusted with a metal shim placed at the anchorage points (See Figure 8). The device should be fixed to the level floor using M10 type bolts for permanent installation. It is also recommended to lay concrete foundation block sizes of which are 700x500 mm for UTS-0660-N for placing the machine on it at least a week ago before delivery.

UTS-0660 Automatic Soil Compactor digital control unit commands the machine automatically to compact specimen by considering the compaction criteria given in the related standards by the user. After completing compaction of selected blow number according to the related standard, the program stops the machine automatically.

Start Button: Starts the program to drive compaction operation by control unit

Stop Button: Sends command to the control unit to stop the program while in any progress. This is not for emergency stop. So, it shouldn’t be used for emergency purpose. When STOP button is pressed, it does not act instantaneously, it waits until the rammer returns to its initial point, in order to avoid the rammer, stay inside the mould. This command clears the current blow number values if it is pressed twice. Keys on the control unit

are not active while the machine is running. Only when the machine is in stop mode, they are active. The machine goes on compacting and counting after pressing “Start” key.

Emergency Stop Button: Powers off the machine in case of emergency. It is rotated clockwise direction to power on.

Whenever the rammer blows, number (#) of drops increases one by one. After performing blows as many as written at the related control unit page, # of drops gets zero and # of batches increases one more. When a new layer is compacted, # of drops starts from 1 and increases as mentioned above. # of drops is seen as many as the number of blows performed through the related control unit page only for that page. But, # of batches is seen as many as the total number of compactions performed at different pages. If you multiply batch amount with drop number, you will get total blow amount for a complete one test.

NOTE: Batch means one compaction session described by means of given drop number. The device stops in order for allowing the user to put 2nd or 3rd layer of soil on the mould.

When returning the previous pages on which the compaction is paused by pressing STOP button and if pressing the START button, the compaction on that page resumes. When pressing STOP button twice, the value number of drops is deleted on the displayed page.

memory.

NOTE: In case the electricity cuts off while the device is on, the given blow parameter by the user becomes ZERO after the device is powered back, as the control panel does not have flash

In case compaction operation is finished or the machine is stopped by STOP key, the rammer always returns to its initial position. For this reason, it is not required the rammer to be taken to its initial position. In order to view compaction pages without performing any blows, option NO must be selected by right arrow key. After this operation, the first compaction setting page is seen on the screen.

Please check below figures for default test types for the device screen. There are 2 different test versions as 4 and 6-inch moulds. To switch between test pages UP and DOWN arrow keys should be used. Also, drop amount is entered via UP arrow button and DOWN arrow button is used in order to decrease the value.

1. Read the requirements of the related standard of the test.
   

1. Prepare the sample for testing according to required standard.
   

3. If it is needed, do the suitable rammer installation by means of related test standard.

To perform a rammer installation, push down the black bar that appears in the Figure 13 and remove the metal bar to which it is connected. Then insert the desired rammer into position as shown in the Figure 14 and push the metal rod back into the housing by pressing the black rod downwards.

After installing the Rammer, reinstall the metal bar in the same way. When placing the rammer, place one of the teeth on the rammer into the rear bracket. It doesn't matter if you place a tooth because the device will automatically adjust the fall height after it has started (Figure 15).

4. If it is needed, do the rammer height settings via adjustment slots. The cam (tappet) can be put in its place either way, no difference.
5. Put the mold in place. To do this, place the mold on the base platen and secure the mold to the base platen with the black head screws through the holes on the mold.
   

6. Fill the mould with the material to be compacted and place the mould on the rotational base platen.
7. If a mould is not positioned on the rotational base platen and the rammer is about to be taken to its initial position, a soft material such as sponge must be placed on the rotational base platen so that the rotational base platen is not damaged.
8. Close the front safety doors.
9. After connecting the power cord, turn on the power switch.
10. Select the required compaction setting page by right arrow.
11. Press START button.

3. Compaction starts.
4. Number of rammer blows is seen on the is “# of drops” line and increases one by one.
5. After the number of rammer blow is accomplished, the machine stops automatically and the rammer returns to its initial position.

4. Compactor stops automatically when the number of blows displayed on the compaction page is accomplished. On the number of batches line, the number of compaction accomplished in first layer is seen as 00001.

12. Open the front safety doors for doing the second layer compaction.
13. Fill the specimen in the mould.
14. Close the front safety doors.
15. Repeat the process from the step 10.
16. Switch off the control unit after accomplishing the number of layers required (Filling the mould according to standard you test).
17. Take the compacted mould out from the rotational base platen.
18. Clean the rotational base platen and the rammer guide.

WARNING: It is important to care that the unit must be switched off and the main cable must be removed before starting any maintenance for user’s safety.

All safety devices must be functional at all times. Damaged protective covers or devices must be replaced as soon as possible. When safety components are replaced, the protective devices are to be properly attached and tested.

We recommend that the device is cleaned of any particles and dust from the scattered specimen after the test with a damp cloth and brush to avoid incrustations which could damage the paint work.

As with all electrical equipment, machine must be used correctly and maintenance and examination must be performed at regular periods. Such precautions will guarantee the safe and sufficient functioning of the equipment. Every week, do a general inspection of the whole device and

every month, do check all the warning and instruction labels if they are intact.

For the drop height correction, the upper cam may be moved by unscrewing the grub screws that fix it in its position. There are two different slots for the cam to be installed so that the rammer height/stroke can be 12 or 18 inches by means of mould size. The cam/tappet which is located at lower section responsible for grabbing the rammer from mould is fixed, it can’t be altered height-wise.

It is recommended that the following wearing parts are regularly cleaned and greased (approx. every 30 compactions) by using a good quality light oil so as to ensure long working life:

Chain: Clean with a cloth damped in solvent and then grease all the links.

Rammer Lifting/Guide Assembly: Clean with a cloth damped in solvent, paying particular attention at the drop height cams found at the two ends of the rod, then well grease. To ensure good greasing, make 5 or 6 drop cycles without the rammer, and then add more grease to the chain and lifting and guide system if it is necessary.

If the machine does not switch on, check whether the emergency stop button stays in a pressed position or not. If the emergency stop button does not stay in pressed position, then fuse in rocker switch is changed with its spare given. You must first plug out the power cable to perform this operation. After that extract the box which carries the fuse with screwdriver and change the fuse with its spare (See Figure 17 and 18).

NOTE: Frequent fuse failures generally indicate that there is some electrical problem with the machine. If problem persists, contact with UTEST.

Maintenance to the equipment is responsibility of the purchaser and must be performed as stated by this chapter. Failing to perform the recommended maintenance actions or maintenance performed by unauthorized people can void the warranty.
