5. Keyswitch: Through this switch the user can select
how the system will be controlled, either from the
pendant control as local use or from the remote
network controller for synchronized applications.
6. Start/Stop motor push-button: Pushing these
buttons, the motor of the EVOP will be switched
on/off.
7. USB connection: A USB memory stick can be
connected in this plug and save the movements
values.
8. Power ok light: This light is on when the system is
connected to power.
9. Emergency stop push-button: Push this button
under an emergency to stop the movement.
10. Communication in plug: This connector allows
communication with the controller in synchronized
applications.
11. Communication out plug: This connector allows
communication with the controller in synchronized
applications.
12. Power supply wireless 1: This is connector 1 for
wireless mode.
13. Power supply wireless 2: This is connector 2 for
wireless mode.
14. Pendant control plug: The operator must connect
the pendant control to this connector to work on
the local mode.
15. B line pressure sensor plug: It is connected to the
pressure transducer at B line or at the cylinder in
port B.
16. A line pressure sensor plug: It is connected to the
pressure transducer at A line or at the cylinder in
port A.
17. Stroke sensor plug: It is connected to the stroke
sensor to get the cylinder position value.
7.3 Pendant Control
EVOP can be operated in local mode from a pendant
control (see Figure 4).
The pendant control has no safety button so it is
connected to the electric cabinet with a 3 meters (10
ft) cable.
1. Start/Stop motor push-button: With this button the
operator can turn on/off the motor on the pump.
2. Stop cycle push-button: When this button is
pushed, the cycle previously selected in the touch
screen stops.
3. Start cycle push-button: When this button is
pushed, the cycle previously selected in the touch
screen starts.
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.
Electric schemes for EVOP are available in L4600
(EVOP12140), L4601 (EVOP140150) and L4602
(EVOP180150).
7.2 Electric Panel
The electric panel includes the controls to switch the
machine on (see Figure 3).
1. Running light/beacon: It lights and sounds when
the pump is performing an operation (lifting,
lowering, etc.).
2. Main switch: Switch to the right to turn on the
equipment. Then, switch to the left to the original
position to turn off the system.
3. Touch screen: In this screen the user can type,
visualize and select the type of movement of the
EVOP while working on the local mode. When the
equipment is used in the remote mode, this screen
blocks and the operator monitors the movements
with the controller.
4. Alarm/reset push-button: The operator must push
this button to reset an alarm once the reason of the
alarm has been solved. This button is only used in
local mode.
