- Fix the generator on the table with the 4 fastening screw 5 use the supplied key. See plan of
drilling (following page)

Noted : This operation is not imperative if the
generator is used for pressures lower than
400 bar ; in this case, insert 4 skates of
stabilization supplied in 4 openings Ø 9 mm
on the crankcase.
- Make sure that o-ring are well positioned on the connectors 4.
> Dirty or polluted gauges must be cleaned
before mounting the pressure generator to
prevent contamination on the hydraulic
circuit. Don't clean the tank with alcohol
Option : cleaning bench (Ref.OP0062)
c) ut into service
> the generators are equipped with
precision valves instrumentation, it is
imperative to observe the following
guidelines to keep your machine in good
working condition.
Filling the device with the fluid
. Open valves 7 and turn the capstan 1 in the direction of clockwise until reaching the stop limit
switch forward.
2. Remove the filler cap on the tank
3. Fill the 3/4 tank with the correct fluid. Don't use other liquids.
> Our devices are mounted and designed to
a standard use. They function with the
fluid provided. Some fluids such skydrol,
castor oil etc... are corrosive and can
damage the o-ring of your device.
On request : we can deliver a device
designed for these fluids.
4. ut the device to be tested and the reference instrument on the connectors 4.
5. Turn completely the capstan in the opposite direction of clockwise until the stop end (the
variable volume of the generator is loaded with the fluid).
6. If you need, complete the level of the tank.
urging the device
. Close the valve 7.Tighten without excess.

RE ENR.101 – Rèv E – Le 08/04/2014 page : 10
2. Unscrew the devices to be tested of the connectors 4.
3. Turn the capstan 1 in the direction of clockwise until the fluid is at the outputs
4. Screw the devices on connectors ; wipe off the excess fluid.
5. Open the valve 7.
6. Turn the capstan 1 in the direction of clockwise until the end stop (the residual air is now
driven).
7. Turn the capstan 1 in the opposite direction clockwise until the stop end position
The pressure generator is ready to use
d) Test run after installing
. Perform a calibration test instrument with a "test" known correct (see chapter procedure) to verify
and validate the operational statues of the pressure generator
Noted : During calibration of instruments with a large volume, the amount of fluid in the pressure
generator may not be sufficient to achieve the desired pressure. in this case the instrument must be
filled as much as possible before being connected to the generator to reduce the useful volume of dluid.
> As an alternative, we provide you with a
hand pump Ref. OP0158 with a reservoir
volume of 327 cm3
2. Lower the pressure by turning the capstan in the opposite direction of the clock hand and remove the
instrument "test". If necessary use the key to start unscrewing the rotating connector
3. The device is now ready to use.

Chap.5 - Cleaning/Maintenance
a) Cleaning
The generator cleaning and checking fluid levels are the only periodic maintenance required. No
additional maintenance should be necessary if all instructions are followed.

RE ENR.101 – Rèv E – Le 08/04/2014 page : 12
We recommend a complete overhaul of the unite every 2 years. This operation can only be
performed by the manufacturer. If necessary, send us your device for maintenance. A complete
assessment of your device will be made and an estimate of rehabilitation will be sent.
Instructions reminders :
- Use only oil H32 for models CEH or water for models CEO. The guarantees of performance and
operation are insured with the use of these oils.
> wear are protection : protects the eyes
against splashes and projections of the
fluid.
- Don't remove the protective cover.
NOTES : For comparators without isolation valves A', the capacity of the pumps 60 cm3 may be
insufficient to fully complete a high volume measuring device. In this case, a solution with
intermediate valve is possible by interposing it between the bench and the device. We repeat the
cycle as many times as necessary. For these applications, a specific kit can be supplied.
It can also fill in advance before mounting the pressure generator.
b) Maintenance
> Valves
Generator and dead weight are equipped with instrumentation valves, it's imperative to observe
the following guidelines :
- Maximum torque applicable abutment valve closed = 4 Nm.
> Tank oil
Make sure the tank contains enough liquid to make the required calibrations. If necessary, fill the
tank with the same liquid as that already used. Don't mix different types or brands of fluids into
the generator and use the recommended oil.
Skydrol, solvents may damage the o-rings mounted on a generator.
Keep clean bench, wipe traces of fluid, and particularly the oil condition in the tank to detect
traces of pollution. If the fluid in the system is dirty, drain the device and remove dirty oil.
> Option : cleaning kit Ref. OP0025 you
will aspirate oil durty present in the
tank.
Don't clean the tank with alcohol
c) Inspection
It's recommend to a service of your device every 2 years. The average response time is 2 weeks.
Cleaning generator, replacement o-rings, testing pressure rise and stability are made.
d) Connection
The device is equipped with a specific connector for less than 250 bar pressure. It is necessary
to orient the ring according to the type of connector correctly.
