1. Safety
1.1 Safety Precautions
Failure to observe and comply with the following
precautions could result in death or serious personal
injury. Property damage could also occur.
• Always wear protective head-wear, ear protectors,
footwear and gloves (at a minimum rigger type
gloves) suitable for safe operation of the tool.
The protective clothing must not interfere with
safe operation of the tool or restrict the ability to
communicate with co-workers.
• Be sure your workplace is safe. Follow the
instructions in your workplace’s standard
operating procedures and be sure to observe all
communicated safety precautions.
• Read and completely understand the safety
precautions and instructions in this manual before
operating the system or preparing it for use. Always
follow all safety precautions and instructions,
including those that are contained within the
procedures of this manual.
• Ensure all hydraulic components are rated to a safe
working pressure of 700 bar (10,150 psi).
• Never set the relief valve to a higher pressure than
the maximum rated pressure of the system. Higher
settings may result in equipment damage and/or
personal injury.
• Do not overload equipment. Never attempt to
move a load weighing more than the capacity of
the system. Overloading causes equipment failure
and possible personal injury.
• Be sure setup is stable before moving load.
• Always perform a visual inspection of the system
before placing it into operation. If any problems are
found, do not use the tool. Have the tool repaired
and tested by an Enerpac Authorized Service
Center before it is returned to service.
• Never use a tool that is leaking oil. Do not use the
equipment if is damaged, altered or in need of
repair.
• Be sure the operator has completed safety induction
training, specific to the work surroundings. The
operator should be thoroughly familiar with the
controls and the proper use of the tool.
• The operator must be of at least the minimum age
required by applicable local regulations, laws and
the facility standard operating procedures.
• Never attempt to relieve hydraulic pressure by
loosening a coupler.
• Never use force to unseat a coupler check ball that
is under hydraulic pressure.
• Take every precaution to prevent oil leaks from
occurring. High pressure oil leaks can penetrate
the skin, resulting in serious injury.
• Do not over-tighten connections; connections
need only be secure and leak free. Over tightening
can cause premature thread failure.

CAUTION
NOTICE

Doc L4540_a 5
• Loose or cross threaded fittings can be potentially
dangerous if pressurized. Never stand directly in line
with any hydraulic connection while pressurizing.
• Never strike the equipment while it is pressurized
or moving load. Components under tension may
become dislodged, allowing them to become
dangerous projectiles. Uncontrolled release of
pressurized hydraulic oil could also occur.
• Avoid striking the equipment at any time, even when
it is not pressurized or moving load. Striking the
tools could cause permanent damage to system
components and may affect its functioning.
• Be certain that no persons are working on or near
any tool before moving of the load begins. Alert all
personnel in advance that the procedure is about
to occur.
• Always maintain communication with the operator
during procedure to avoid accidents. Use hand
signals, two- way radios or other appropriate forms
of communication (as required by applicable laws and
regulations) if the load is not visible to the operator.
• Operate Pum per Point Lift System (EVOP) as
required to ensure that the load is moved evenly
and at a controlled rate.
• Closely watch the load at all times during operation.
Stop work immediately if the load becomes
unstable or appears to be moving unsteadily.
• Immediately replace worn or damaged parts.
Use only genuine Enerpac parts from approved
distributors or service centers. Standard grade
parts will break causing personal injury and
property damage. ENERPAC parts are designed to
fit properly and withstand high loads.
• To minimize risk of personal injury keep hands
and feet away from the tool and workpiece during
operation.
• High voltage is present inside the pump even when
motor is off. Always be certain that the pump is
stopped and disconnected from AC power supply
before performing any inspection, maintenance or
repair procedures.
• Do not leave the pump unattended in the workplace
when connected to AC power supply. Take all
reasonable precautions to avoid unauthorized use.
• Take precautions so that the pump is not switched
on accidentally.
• If it is not possible to unplug the pump power
cord from the AC power outlet, the power must be
turned off and locked out at the AC power supply.
• Always disconnect the pump from AC power
supply before transporting it.
• Do not unplug the pump by pulling on the cord. To
unplug, grasp the plug, not the cord.
• If the cord and/or plug are damaged, do not
connect the pump to a live electrical outlet. Repair
or replace the damaged items as required and be
sure the grounding conductor is properly wired
before reconnecting the pump to the outlet. Consult
a qualified electrician if grounding conductor
wiring procedures are not completely understood
or if there is any doubt as to whether the pump is
properly grounded.
• Do not modify the plug provided with the pump.
If the plug will not fit in the outlet, have a proper
outlet installed by a qualified electrician.
• If the pump must be reconnected for use on a
different type of electric circuit, the reconnection
should be made by a qualified electrician. After
the reconnection, the pump should comply with all
local codes and ordinances.
Failure to observe and comply with the following
precautions could result in minor or moderate
personal injury. Property damage could also occur.
• Ensure components are protected from external
sources of damage, such as moving machine parts,
sharp edges, weld spatter, corrosive chemicals
and excessive heat or flame.
• Keep hydraulic equipment away from flames and
heat. Excessive heat will soften packings and
seals, resulting in fluid leaks. Heat also weakens
hose materials and packings.
• For optimum performance, do not expose hydraulic
equipment to temperatures of 150˚F [65˚C] or
higher. Protect all hydraulic equipment from weld
spatter.
• To prevent damage to pump electric motor, check
specifications. Use of incorrect power source will
damage the motor.
• Do not use electric pumps in an explosive
atmosphere. Adhere to all local and national
electrical codes. A qualified electrician must do
installation and modification
• Protect hoses and cylinders from weld spatter.
• Avoid damaging the hydraulic hose. Avoid sharp
bends and kinks when routing hydraulic hoses.
Using a bent or kinked hose will cause severe
backpressure. Sharp bends and kinks will internally
damage the hose leading to premature hose failure.
• Do not drop heavy objects on hose. A sharp impact
may cause internal damage to hose wire strands.
Applying pressure to a damaged hose may cause
it to rupture.
• Do not lift hydraulic equipment by the hose or
couplers. Use the lifting handles provided on
cylinders and clamp assemblies.
• Do not pull on a hose that is connected. If pulling
forces are exerted on a hydraulic coupling the hose
and coupling interface will weaken which may
result in the hose bursting out of the coupling.
• Always lift a hose by the hose itself, whilst
supporting the coupling.
• Do not handle pressurized hoses. Escaping oil
under pressure can penetrate the skin, causing
serious injury. If oil is injected under the skin, see a
doctor immediately.
• During assembly the hose must be supported by
necessary use bend guides to prevent twisting of
the hose.
• Change worn or damaged hoses immediately.
• Do not use dirty or corroded couplings.
CAUTION

6Doc L4540_a
Failure to observe and comply with the following
precautions could result in property damage and/or
void the product warranty.
• In severe service conditions, be aware that the
EVOP system must be inspected, cleaned and
lubricated more frequently than normal.
• If oil leakage is present, replace seals as required
before placing the tool back into service.
• If any tool is dropped from a significant height,
have it inspected and checked for proper operation
before placing it back into service.
• While moving the hoses, prevent the couplings
being dragged over the ground.
• Always follow the inspection and maintenance
instructions contained in this manual. Perform
maintenance and inspection activities at the
specified time intervals.
• Hydraulic equipment must only be serviced by a
qualified hydraulic technician. For repair service,
contact the Enerpac Authorized Service Center in
your area.
• To help ensure proper operation and best
performance, use of Enerpac oil is strongly
recommended.

3. Introduction
3.1 Overview
The Pump Per point Lift System (EVOP) enables control
movement of one lifting point remotely. The load can be
lifted/lowered using single or double-acting cylinders or
even for pulling cylinders.
Depending on the application, the EVOP can be operated
individually or simultaneously in a synchronously mode
with a Coordinated Lifting Network Controller (refer to
controller’s instruction sheet for more detail information).
This network controller can remotely control up to 12
EVOPs. In this way, the connection capacity of lifting or
lowering points is increased, maintaining the precision
and characteristics as a single unit. The synchronization
can be obtained by motor inverters or by electrovalves.
Built in warning and stop alarms for optimum safety,
EVOP has a great accuracy of the cylinder position due
to each cylinder having a dedicated powerpack.
3.2 Application
The EVOP can be used in a wide variety of lifting,
lowering and pushing applications, such as: bridge
deck lifting for bearing maintenance, machinery lifting
and moving, skidding to move structures and buildings,
and shipbuilding applications.
3.3 Delivery Instructions
Upon delivery all components must be inspected for
damage incurred during shipping. If damage is found
the carrier should be notified at once. Shipping damage
is not covered by the Enerpac warranty. The carrier is
responsible for all repair and replacement costs resulting
from damage in shipment.
4. Transport
The frame has two forklift truck pockets for forklift lift, and
four hoisting certified eyes for lifting with cranes.

7. Initial Setup
7.1 Electric Connections
EVOP is factory equipped with 3 phase electrical cable
for the given voltage. Connect the equipment to power
adhering to all applicable local and national codes.
The disconnection and line circuit protection will be
provided by the customer. Line circuit protection will be
115% of motor full load current at maximum pressure of
application.
EVOP can read the work pressure at the outlets of the
hydraulic block or at the inlet of the cylinder.
EVOP pumps are supplied from the factory with pressure
transducers on outlet of the hydraulic block as standard.
The equipment cannot give both readings at the same
time. Be sure to disconnect the pressure transducers
not being used in each operation.
Pressure transducers at oil outputs A and B (Figure 2,
items 14 and 17) are connected to the electrical panel by
a threaded connector (Figure 3, items 16 and 15). If the
operation requires higher reading precision, manually
release the threaded connector of each pressure
transducer before conecting the cylinder’s pressure
transducer.
Connecting to pressure transducers located on the
cylinder will require an extension cable depending on
the distance from the pump to the cylinder. Contact
Enerpac for more details.

These are the buttons shown in this screen:
1. Position sensor scale: Depending on where the
stroke sensor is placed, the user must select one
of these two options (see Figure 15).
Figure 15: Position Sensor Scale Selection
When the cylinder’s plunger movement and the stroke
sensor’s wire are extending (positive movement),
the movement is called Direct. When the cylinder
is extending but the stroke sensor wire is retracting
(negative movement) the movement is called Indirect.
Refer to Figure 16 for further details.
Figure 16: Direct and Indirect Layout
2. Cylinder calibration selection: The user must set
if the calibration is going to be carried out or not,
depending on the type of cylinder used. Refer to
Figures 17 and 18 for details.
Figure 17: Cylinder Calibration Selection
DIRECT INDIRECT
Calibration operation must be carried out depending on
how the hook of the stroke sensor is attached. If the
hook is attached to the cylinder rod, or if an internal
stroke sensor is used, the calibration must be done. If
the hook is attached directly to the load to be moved,
then the calibration must be avoided.

In this screen the user can enter the parameters of
the elements used in the EVOP movements, such as
the cylinder installed for the application, the stroke
sensors and the pressure transducers used to set the
calculations of the movement.
In the boxes the user can type the following data (refer
to Figure 20 for the position number):
1. Units button: The user can switch a different units
system pushing this button. The units can be
international for the International System of Units,
or Imperial for the Imperial System of Units.
2. Cylinder type: The user can select the type of
cylinder being used with the HPU (single/double
acting).
3. Position span: The user must type the maximum
range of the stroke sensor which monitors the
cylinder.
The standard stroke sensors position spans are 100,
125, 375, 500 ,750, 1000, 1250 and 2000 mm.
4. Cylinder stroke: The user must type the maximum
stroke of the cylinder.
5. A line pressure span: The user must type the
maximum range of the A line pressure transducer.

area of the pushing side of the cylinder conected
to A line.
8. B line effective area: The user must type the surface
area of the pulling side of the cylinder conected to
B line.
Information of sensors and cylinders is available either
on the product label or online at www.enerpac.com.
For single acting cylinders, B line parameters are
blocked and appear shaded.
Figure 21: Spans Screen Single Acting Cylinders
8.5 Offset Screen
Figure 22: Offset Screen Details
Offset is generally used to have a dimension reference
when a load is going to be lifted to an unknown
dimension and that load is subsequently lowered to
the same location. Since the wire of the stroke sensor
will normally need to be extended a short distance to
engage the bottom of the load, the offset screen can
save that value so the user can reference that starting
point after the lift is completed. By assigning an offset
value prior to start lifting the load, the user will have a
reference point where the lift started.
“A” value normally represents the absolute extension of
the stroke sensor between 0 and full extension. When
the user presses and holds the Offset button (A=0), the
current “A” value is stored in the memory as “Z”, and “A”
is reset to zero. “A” now becomes the reference value
for the starting point of the lift. When the lift is complete,
the user can press Reset button (Z=0) to reset “A” back
to normal value.
In this screen the following elements are shown:
1. Pressure button: Pushing in the pressure icon, the
operator can check the internal pressure of the
cylinder.
2. Pressure line: This section shows the pressure at
A line (big chamber) and B line (small chamber) of
the hydraulic circuit.
3. Manual button: Select this button to activate
the manual mode operation. When this button is
selected, the background color of the button will
become green. Use this button to make small
movements in the application. Refer to paragraph
“8.10 Manual Screen” and “9.4 Manual Mode” for
further details concerning the manual movements.
4. Upward/Downward buttons: When the manual
button is selected, the operator must select
the type of movement to be executed between
upward (the plunger moves out of the cylinder) and
downward (the plunger gets in the cylinder).
5. Offset button: Push and hold this button for 3
seconds to convert value A into 0 and Z will keep
the current value of A.

The offset value does not disappear when the equipment
is turned off or there is a power failure. This value is
maintained until the operator performs a reset of the
Offset value.
6. Reset Offset button: Push and hold this button for
3 seconds to convert value Z into 0 and A will take
the current value of Z and will add it to the current
value.
Af= Ai+ Z
7. Movement values: There are some values that the
system can show during the movement. These are:
- A (Absolute position): The absolute position is the
position of the cylinder’s stroke sensor taken from
the initial zero. This initial zero is the zero set in
the calibration screen (refer to paragraph 8.6 for
further details).
- Z (Offset variable): Memory variable for a
movement reference.
- L (Load withstood by cylinder): This value shows
the load being withstood by the cylinder.
8.6 Calibration Screen
Figure 23: Calibration Screen Details
When the stroke sensor wire is connected to the
cylinder‘s rod, or if an internal stroke sensor is used,
the system reads the extended length of the sensor
(A value). In that moment, A has a real reading of the
sensor. Refer to Figure 23 for details.
To equalize the stroke sensor position with the rod
position, the user must carry on the calibration of the
cylinder. When the calibration work is performed, the
cylinder will have value A = 0 when retracted.
This screen has similar elements to the Offset screen.
Two buttons are different:
1. Calibration: If the calibration is allowed, based on
the location of the stroke sensor (refer to paragraph
8.3.1 for further details), this button allows calibrating
(equalize the cylinder and the stroke sensor) and
will set the Absolute position of the cylinder (A = 0).
The user must push and hold for 3 seconds this button
to make the value effective.
CAUTION
This step should only be performed with the sensor
connected to the cylinder’s rod fully retracted to
ensure the sensor will be properly calibrated.
2. Reset Calibration button: If something goes wrong
during calibration work, this button allows the
operator to get back to the previous value of the
Absolute position and reset the calibration done.
Figure 24: A value in a general purpose cylinder
8.7 Tare Screen
Figure 25: Tare Screen Details
This screen has similar elements to the Offset screen.
Two buttons are different:
1. Tare: This button allows taring (reducing the
displayed load to zero in order to remove the effect
of lifting beams or other support structures). This
will set the displayed load, L=0. The user must
push and hold for 3 seconds this button to make
the value effective.
2. Reset Tare button: If something goes wrong during
tare work, this button allows the operator to get
back to the previous value of load and reset the tare
done.

8.8 Pressure Sensor Calibration
Screen
Figure 26: Pressure Sensor Calibration Screen Details
This screen is used when the operator needs more
accuracy when reading the load in the cylinder.
The user can type manually the minimum and maximum
analogical values given by the calibration certificates of
pressure transducers.
The screen shows the pressure (bar) that the machine
has in each line and the real value of analogical signal
(mA).
The parameters that can be typed are Low Value (mA)
and High Value (mA). These values must be given by the
manufacturer.
Furthermore, the operator can type the serial number of
the transducer in order to have a trace reference.
8.9 Network Screen
Figure 27: Network Screen Details
In this screen the operator can select the HPU code of
the equipment.
The code is used by the Coordinated Lifting Network
Controller to identify each pumps location on the
network. Make sure not to assign the same code to two
different pumps on the same network

8.10Manual Screen
Figure 28: Manual Screen Details
This screen belongs to the movements section. In this
section the user must select the type of movement
which is going to be executed.
In the case of the manual movements, the user can
move the cylinder of the HPU having a total control
of the movement. The user can extend or retract the
cylinder plunger by pushing and holding the start cycle
button and stop the movement just releasing the button.
This work mode is used to make small positioning
movements in the application.
The user can find the following elements in this screen
(refer to Figure 28 for reference numbers):
1. Manual button: Select this button to activate the
manual mode. When this button is selected, the
background color of the button will become green.
2. Extend/Retract buttons: When the manual button
is selected the user must also choose a direction
of motion. This can be extend to get the plunger
out of the cylinder, or retract to get the plunger into
the cylinder. The user must set what direction of
movement is going to be executed.
3. Reset Relative Position button: This button resets
the relative position of the cylinder to zero. Push
this button to reset this value. For further details
about the relative position, refer to the point 5 of
this section.
4. Flow button: The user can type the flow of the HPU
and control the speed of the movement. This value
is a percentage and can be typed between 30 and
100% of the total flow. It corresponds to the speed
of the motor.
5. Movement values: There are some values that the
system can show during the movement. These are:
- A (Absolute position): The absolute position is
the position of the sensor taken from the initial
zero. This initial zero can be adjusted to match the
cylinder plunger position in the calibration screen
(refer to paragraph 8.6 for further details).
- R (Relative position): The relative position is the
position of the plunger of the cylinder taken from
the last zero set point. This is the reference value
that the system uses to maintain synchronization
between lifting points.
To reset position refer to point 3 of this section).
- L (Load withstood by cylinder): This value shows
the load withstood by the cylinder in the current
moment.
Load values are obtained through the calculation of
the pressure in the pressure line of the cylinder and the
effective area typed in the spans screen (paragraph 8.4).
These values therefore will be approximated with some
error margin.
Some points are common elements in the movements
screens. This elements will not be explained again in the
following paragraphs.
8.11Preload Screen
Figure 29: Preload Screen Details
Preload screen contains similar elements to the Manual
screen (Figure 28). The only changes are elements
shown in Figure 29.
In this work mode, the operator has to define a target
load that the cylinder must sustain. Cylinder piston
will automatically move until it comes to support the
specified load.
There are two important elements in this screen:
1. Preload button: Select this button to set the
preload movement in the system. When this button
is selected, the background color of the button will
become green.
2. Final Load parameter: The user must type the final
load that the cylinder must reach to finish the cycle.
Enerpac recommends setting the final load value to less
than 10% of the expected load.
