CHAPTER III -- DESCRIPTION OF CONTROLS A. ELECTRONIC CONTROL PANEL

The electronic control panel processses the analog signal from the pressure transducer in the Concrete Tester, then displays it in accurate digital values. Keys are provided to set initial operating parameters, to activate gathering of data, and to process the data once it has been collected. * Please refer to the Operating Instructions for the 37-4855 ADR Digital Readout Unit for further details.

B. HYDRAULIC PUMP CONTROLS

1. POWER - The black toggle switch (On/Off) on top of the motor is used to switch power to the hydraulic pump.

2. CONTROL HANDLE - This control has four positions.

RETRACT - When the handle is in this position, with the pump motor running, the loading ram

retracts. By stopping the motor, speed of retraction may be increased.

HOLD - When the handle is in this position, the load applied by the ram is held unchanged.

METERED ADVANCE - When the handle is in this position, with the pump motor running, the ram slowly advances at a rate or speed which depends upon the METERING VALVE setting. Use this position when the specimen is being loaded.

FULL ADVANCE - When the handle is in this position, with the pump motor running, the ram advances very quickly. Use this position to close the gap quickly between the platen and specimen. The FULL ADVANCE stops when you set the handle to METERED ADVANCE and the platen advances at the rate set by the metering valve knob.

3. METERING VALVE - Turn this knob to increase (counter clockwise) or decrease (clockwise)

the loading rate. During the test, the pace deviation display on the control panel should be held close to 0% by carefully turning this knob in the proper direction. Turning this knob counter clockwise produces positive deviation; turning it clockwise produces negative deviation or slows the rate of loading.

NOTE: This metering valve is monitored by the bars on the PACE DEVIATION RATE display. Try to keep these bars within the range close to "0" (Zero).

5 Rev. 2:01/2001

CHAPTER IV -- PROCEDURE FOR BASIC OPERATION The procedure for normal operation is described in this section. Normal operation consists of: (1) entering initial operating parameters, (2) compressing specimen to gather data, and (3) either displaying data, printing it on the optional printer, or downloading to a computer.

For storing data in battery backed internal memory and transferring it to an external computer, please refer to the Operating Instructions for the 37-4855 ADR Digital Readout Unit.

A. WARM UP THE ELECTRONIC CONTROL BOX.

* Please refer to the Operating Instructions for the 37-4855 ADR Digital Readout Unit for further details.

B. Place the specimen on the top of the lower platen.

1. There should be about 1/4" (6.35 mm) clearance between the upper platen and the concrete specimen. If necessary, install spacers on lower platen.

For installation of upper platen assembly, see Chapter II, Step G.

2. Center the specimen under the upper platen.

C. Set Parameters/Controls on Electronic Control Panel.

* Please refer to the Operating Instructions for the 37-4855 ADR Digital Readout Unit for further details.

D. Compress the specimen.

1. With the control handle on RETRACT position, turn the metering valve knob fully clockwise. Turn the hydraulic pump on by pushing the toggle switch to the ON position.

2. Check that there is approximately 1/4" (6.35 mm) clearance between the upper platen and the

concrete specimen before starting compression. Turn the control handle to FULL ADVANCE position, watching until the upper platen is within 1/8" (3 mm) of the specimen. Turn the control handle to METERED ADVANCE and press TARE key to zero the reading. The display will read "000000". The red bar on the Pace Deviation Rate display will appear at the extreme left.

WARNING: Take precautions to protect the operator and other laboratory personnel from possible flying particles.

NOTE: If loading the first half (first 50%) of loading phase at high rate (FULL ADVANCE mode) as allowed by ASTM C-39, be sure to press TARE key to zero the reading while in the METERED ADVANCE mode before rapid loading.

3. Adjust the METERING VALVE counter-clockwise to keep the moving bar on the pace

deviation rate meter near the center of the scale. The bar is allowed to fluctuate within the +20% scale to meet ASTM. If the bar goes off scale, adjust the METERING VALVE to compensate.

For explanation of flashing bars on the Pace Deviation Rate display, please refer to the Operating Instructions for the 37-4855 ADR Digital Readout Unit.

6 Rev. 2:01/2001

4. Load the specimen at the controlled rate until the specimen breaks.

5. When breakage occurs, turn the control handle to RETRACT. The upper platen will retract. If the control handle is not turned to RETRACT, the upper platen will continue to move down.

The load display will remain at the value at which the specimen broke (known as Peak Load) until the TARE key is pushed.

The pace deviation bar will become blank after the Peak Load is reached. It will continue to have no display until the TARE key (tared zero) is pushed.

E. Please refer to the Operating Instructions for the 37-4855 ADR Digital Readout Unit for printing test results.

F. Please refer to the Operating Instructions for the 37-4855 ADR Digital Readout Unit for displaying

stress results.

G. After each test, remove the broken specimen and clean out any breakage. H. To start another test with the same size specimen, position specimen, press the TARE key and return

to Step D. For a different size or type of specimen, return to Step C, #6. I. When all testing is completed, push the toggle switch to the OFF position to turn off power to the

hydraulic pump, press the ON-OFF button on the front electronic control panel to turn off the display screen, and depress the rocker switch on the back of the electronic control box to turn off the system.

CHAPTER IX -- SERVICE INSTRUCTIONS A. MAINTENANCE

1. Clean up specimen breakage after each test.

2. The hydraulic pump motor has a thermal protection. If the motor is overheated, the red button on top of the motor pops up. Wait until the motor cools off. Depress the red button.

3. Keep level of oil in reservoir between 1/2 to 1" (12.7 to 25.4 mm) below the top of the filling

opening (2 gal. capacity) when the cylinder is fully retracted.

4. Drain, clean and replenish the reservoir with high grade hydraulic oil (ELE/Soiltest Part No. 9806-0017) yearly or more often if necessary. The frequency of oil change will depend upon the general working conditions, severity of use and overall cleanliness and care given the pump.

Suggested method of removing hydraulic oil could be using a drill-powered pump with flexible

tubing that will not require priming of the pump. Such pumps are available at your local hardware store. Possible model number 55432 “chuckmaster” manufactured by Simer. Discard used oil in accordance to all applicable laws.

CAUTION: Do not remove hydraulic oil when hot.

5. Oil the spherical ball on the upper platen once a week with "Oak Protect 408" (ELE/Soiltest

Part No. 9806-0022).

6. Replace fuses as needed. * Please refer to the Operating Instructions for the 37-4855 ADR Digital Readout Unit for further details.

WARNING: Be sure to turn the unit OFF and DISCONNECT the power cord before replacing or checking any fuse.

7. Electrical components should be checked by a qualified electrician.

8. A relief valve situated on top of the reservoir and parallel to the fill opening is factory set.

Altering the setting can cause serious damage. Any changes should be made by a skilled calibrator.

B. REMOVAL OF AIR FROM HYDRAULIC SYSTEM

1. Center spacer on the lower platen.

2. Push the toggle switch to the ON position to turn the pump on. Turn the control handle to FULL ADVANCE to momentarily apply pressure of 10,000 lbf.

3. Turn the control handle to RETRACT.

4. Let the pump run in RETRACT position for 15 minutes.

5. Repeat this process two or three times to ensure the air is completely released.

6. Push the toggle switch to the OFF position to turn the pump off.

2. The pressure transducer is located under the electronic chassis. A defective transducer

requires replacement and recalibration of the unit. Contact ELE/Soiltest Service Department. For replacement purposes, note the model number and value of the transducer to be replaced.

D. TROUBLESHOOTING

1. If the control panel does not function, check the fuse in the Digital Readout.

* Please refer to the Operating Instructions for the 37-4855 ADR Digital Readout Unit for further details.

WARNING: Be sure to DISCONNECT the power cord before you replace the fuse.

2. If the control valve does not work, dirt may be holding the spool valve (Fig. 3, #26) in

position. (This spool must be free to slide in the body to control the loading rate of the cylinder.) Clean the spool by removing end plugs #23 and #28, gently removing the spring #25, and pushing the spool out with the eraser end of a lead pencil. Look for contamination, clean the spool and reinsert in housing, checking that it slides freely. Replace the spring and end plugs. Put clean oil in the reservoir.

. Cleaning the spool is the only field repair that should be attempted on the valve. For any other

problems, return the valve to ELE/Soiltest Service Department for replacement.
