seconds after the completion of the previous test, the In-

5.0 ELECTRICAL/MECHANICAL DATA

5.1 User Connections

dicator begins waiting for the load to exceed the thresh­old (0.5% of Full Scale), which signals the beginning of
the next test. During a test, the Indicator will continue
monitoring for peak load until the live load falls below
50% of peak load. Once the live load drops below 50%
of peak, the test ends and the peak load will be displayed
on the screen. The peak will remain on the screen until
a) <ZERO> is pressed or b) a new test is started.

NOTE: Before <ZERO>ing the load make sure that
the piston is floated and the loading platen is close
to the specimen.

6.0 HYDRAULIC CONTROL VALVE

6.1 Metered Advance Position

Placing Control Handle No.1 (see Figure 1) into the me­tered advance position allows the operator to adjust the
rate of loading through the use of Control Knob No. 2.
The adjustment for increasing the rate of loading is to
turn Knob No. 2 counter-clockwise. To decrease the rate
of loading, turn the Knob No. 2 clockwise. CAUTION:

Do not over-tighten Control Knob No. 2.

When testing concrete cylinders, the rate of loading
must conform to ASTM C 39 specifications. For a hy­draulically operated testing machine, the load must be
applied at a constant rate within the range of 20 to 50
psi/sec. Knob No. 2 controls the rate of loading. For 6in
(150mm) diameter concrete cylinders, the loading rate
should be 565—1,413 lbs/sec., or 34,000—84,000 lbs/
min. For 4in (100mm) dia. cylinders, the rate would be
251—629 lbs/sec. or 15,060—37,710 lbs/min.

For Load Indicators with no rate of load display, a read­ing of 10,000 lbs. on 10 seconds is a good average and
is easily set through the use of Control Knob No. 2 and
a watch with a second hand.

6.4 Retract position

Placing Control Handle No. 1 into the retract position re­leases all pressure in the hydraulic cylinder allowing the
piston to retract to it’s start position. It is not necessary to
retract the piston fully between tests. A daylight opening
that will allow the specimen to be inserted and removed
is all that is required.

NOTE: During continuous operation of the machine,
the Flow Control Valve will go through a significant
temperature rise. This is not a cause for alarm, as
the temperature rise will not affect the operation of
the testing machine.

6.2 Full/Advance Position

Placing Control Handle No. 1 into the rapid advance
position causes the piston to advance rapidly at an un­controlled rate. This is normally used for pre-loading a
specimen or rapidly advancing the piston to reduce the
daylight opening between the specimen and the platen.

CAUTION: When pre-loading a specimen, watch the
machine’s load indicator to prevent overloading, or
premature failure of the specimen may occur.

WARNING!: DO NOT ALLOW THE MACHINE TO

TRAVEL BEYOND THE MAXIMUM PISTON STROKE
TAG LOCATED ON THE FRONT OF THE LOAD
FRAME. OVEREXTENDING THE HYDRAULIC RAM
MAY RESULT IN DAMAGE TO THE SEALS AND
WILL CAUSE THE UNCONTROLLED RELEASE OF
HYDRAULIC FLUID UNDER PRESSURE.

6.3 Hold Position

Placing Control Handle No. 1 into the hold position (see
Figure 1) stops the loading of the specimen and holds
the pressure on the specimen at that point.

6.6 Sequence of Operation

1. With Pump Motor switched off, carefully center
specimen in testing machine.

2. Turn Control Knob No. 2 clockwise to a snug posi­tion. Never over tighten. (If Knob No. 2 has already
been adjusted as in section 6.1, this step may be
skipped until a specimen of different size is tested.

3. Position Valve Control Handle No. 1 to a “metered
advance” position.

4. Switch on pump motor.

5. If a preload of the specimen is desired, position
Valve Control Handle No. 1 to “full advance”. Cau-

tion is required to avoid overload or failure of
the specimen.

6. Watch the display closely. When the desired pre­load has been attained, move the Valve Control
Handle No. 1 to the “metered position”.

9. To release pressure so that the platen will return af­ter a test has been completed, position Valve Con­trol Handle No. 1 to the “retract” position.

10. For repetitive testing of identical specimens, Control
Knob No. 2 can be preset with a stopwatch, then
locked in position by tightening the thumbscrew lo­cated beneath the knob.

6.7 Maintenance & Safety Precautions

6.7.1 Hydraulic Pump & Flow Control Valve

This two-stage hydraulic pump incorporates precision
design and engineering features. Peak efficiency for ei­ther continuous or intermittent operation is assured at
the full range of pressures up to 10,000 psi. You will
have uninterrupted, trouble-free service if you keep it
clean and free of dust.

7. To increase the rate of loading, turn Control Knob
No. 2 counter-clockwise. To decrease the rate of
loading, turn Control Knob No. 2 clockwise.

8. To hold pressure at any desired point, position Valve
Control Handle No. 1 to the “hold” position.

6.7.2 Safety Precautions

WARNING!: To avoid possible injury:

• Disconnect the pump fromits electrical supply be­fore performing maintenance or repair procedures.

• Repairsandmaintenanceshouldbeperformedina

dust-free area by a qualified technician.

• Shouldahydraulichoseeverrupture,burstorneed

to be disconnected, immediately shut off the pump
and shift the control valve to the retract position to
release all pressure and allow the machine piston to
return to the at-rest position. Cycle the control valve
twice to its retract position to make sure all pressure
is released. Never attempt to grasp a leaking

hose under pressure with your hands. The force
of escaping fluid could cause serious injury.

• Donotsubjectthemachineshydraulichosestopo­tential hazard such as fire, extreme heat or cold,
sharp surfaces or heavy impact. Do not allow the
hose to kink, twist, curl or bend so tightly that oil flow
within the hose is blocked or reduced.

• Periodicallyinspectthehosesforwearbecauseany

of these conditions can damage the hose and pos­sibly result in personal injury. Should a hose need
replaced, contact Gilson Company, Inc. with your
machine model number and capacity for replace­ment parts.

6.7.3 Hydraulic Fluid Level

• The frequency ofoilchangeswilldependupon the

general working conditions, severity of use and over­all cleanliness and care given to the testing machine
and the hydraulic pump. An air hose should never
be used to clean the machine or pump as it will blow
dust into the hydraulic system and cause damage
to the hydraulic pump and load control valve. The
oil should be changed at least every three hundred
(300) hours of use under severe working conditions,
where dust contamination of the oil is quite likely to
happen. When changing the oil drain, flush and refill
the reservoir with Dextron III Automatic Transmis­sion Fluid.

6.7.4 How to Operate the Pump

1. Make sure all valve and hose fittings are tight. Plug
in electric motor.

2. Set valve in the retract position, set switch on run,
and let pump idle for a few minutes.

3. Place a concrete test cylinder in the machine and
run piston out to its full travel several times to elimi­nate air from the system. The pump is now ready to
be put into regular operation.

• When checking the oil level, fully retract the ma­chines hydraulic cylinder to the at-rest position and
disconnect the power supply. Clean the area around
the filler plug and remove the plug.

• Formachinessuppliedwith3/4hppump, maximum

capacity is when the oil is 1-1/2in (38mm) below the
cover plate with the cylinder retracted.

• Formachinessuppliedwith1/2hppump, maximum

capacity is when the oil is 2in (50mm) below the cov­er plate with the cylinder retracted.

• When adding oil, use only Dextron III Automatic
Transmission Fluid. To fill, insert a clean funnel

with filter, add oil slowly being careful not to overfill
the pump. Check oil level when finished and remove
any oil if pump is overfilled. Check to see that the
breather-hole in the filler cap is open to prevent the
build up of excessive air pressure in the reservoir,
and to assure that the cylinder retracts smoothly,
then replace filler cap.

6.7.5 Troubleshooting

Correcting Minor Hydraulic Problems

The hydraulic unit should be observed constantly for out of the ordinary performance and unusual noises. If any of
these are present, shut off pump and take corrective steps immediately to avoid possible expensive repairs later on.
Some of the most common minor problems and their remedies are listed:

PROBLEM CAUSE REMEDY

Improper advance or return. Air in circuit, oil supply low. Add oil.

Improper advance or return. Dirt in system causing valves to lock open.

If trouble is not cleared up by above remedies,

Improper advance or return.

trouble may be due to dirty or plugged up
strainer screen.

Flush out entire oil system and fill
with new oil.

Drain oil. Next remove pump
base cover and clean or replace
screen.

CAUTION: Do not operate pump without screen, as particles of dirt will be sucked into pump and
valve mechanisms, seriously damaging valve seats.

PROBLEM CAUSE REMEDY

Unable to reach pressure. Same as above. Same as above.

Necessary to add oil often. Oil leaks.

Check for broken lines, loose fittings
or connections.

Noise in hydraulic system. Air in system. Low on Oil. Add oil. Run pump to work out air.

If the above corrective measures fail to make the pump function properly, it is recommended that you notify Gilson
Company, Inc. or a qualified service representative. Under no conditions allow unqualified personnel to attempt
to repair the pump, particularly the pump block unit or control valve unit, as serious and irreparable damage may
result.
