IMPORTANT RECEIVING INSTRUCTIONS
Visually inspect all components for shipping damage. If any shipping damage is found, notify carrier at
once. Shipping damage is NOT covered by warranty. The carrier is responsible for all repair or replace-
ment costs resulting from damage in shipment.
SAFETY FIRST
Carefully plan your system by selecting components designed to perform the intended operation and
which will adequately perform with existing equipment. Always check the product limitations regarding
pressure ranges, load capacities and set-up requirements. The system operating pressure must not
exceed the pressure rating of the lowest rated component in the system. Read all CAUTIONS,
WARNINGS, AND INSTRUCTIONS included with, or attached to, each product. Follow all safety precau-
tions to avoid personal injury or property damage during system operation. ENERPAC CANNOT BE
RESPONSIBLE FOR DAMAGE OR INJURY RESULTING FROM UNSAFE USE OF PRODUCT, LACK
OF MAINTENANCE OR INCORRECT PRODUCT AND SYSTEM APPLICATION.

Auto-Coupler Control Box
Contact ENERPAC when in doubt as to safety precautions, or applications.
PRODUCT DESCRIPTION
The ACCB-1 Automatic Coupler Control Box is compatible with Enerpac’s Two-Port Automatic Coupler
(WCA-62) and Automatic Coupler System Pump (WEQ-4005).
For information on installation and operation of the pump, refer to the pump instruction sheet, L-1740.
The automatic coupler control box provides automatic or manual control of your Two-Port Automatic
Coupler station. Indicator lights inform you when the auto-coupler is advanced or retracted, and whether
the fixtures are clamped or unclamped.
Two pressure switches, three proximity switches, and three proximity elbow switches are included to work
with the ACCB-1. The pressure switches monitor system pressure when clamping and unclamping the
workpiece.
The proximity switches inform the PC when the auto-coupler is advanced and retracted and when the
pallet is in position for the coupler.
Pre-programmed safety features ensure proper sequencing of automatic coupler and fixture operations.
OPERATION
Starting the system
1. Turn the ‘MAN OFF AUTO” key switch to “OFF” prior to powering up the ACCB-1 Control Box. This
will prevent inadvertent start-up of the automatic or manual operating sequence.
2. Pull out the “EMERG. STOP” button.
NOTE: The “EMERG. STOP” palm button must be pulled out to run the system.
3. Turn on the power supply to the system.
4. With the key switch on “OFF,” the auto-coupler base station automatically retracts to the home
position, if necessary, after a 3 second delay. The “AUTO-COUPLER RET” red pilot light flashes
during retraction.
5. The “AUTO-COUPLER RET” red pilot light will remain lit to signal that the auto-coupler is fully
retracted and ready to receive a fixture.
NOTE: Afixture cannot move into the load position unless the auto-coupler is fully retracted and the
“AUTO-COUPLER RET” light is lit.
“AUTO-MODE” sequence of operation
1. To initiate the AutoMode sequence of operation, the auto-coupler must be fully retracted and the
“AUTO COUPLER RET” light must be lit. Turn the “MAN OFF AUTO” key switch to “AUTO.”
2. The “FIXTURE SENSOR” proximity switch senses when a fixture moves into the load position.
3. As the auto-coupler extends to engage the fixture, the “AUTO COUPLER RET” red pilot light will go
out. The “AUTO COUPLER ADV” green pilot light flashes during extension.
4. After complete extension, the “AUTO-COUPLER ADV” green pilot light remains lit. The pump will
continue to run for 3 seconds.
5. The system then retracts the cylinders to unclamp the workpieces. The “FIXTURE UNCLAMP” red
pilot light flashes during unclamping.
6. When unclamping is complete, the “FIXTURE UNCLAMP” red pilot light remains lit. The pump will
stop after 90 seconds if no other sequence is initiated.
7. Remove completed workpieces from the fixture and place new workpieces into the fixture.
8. Press the “FIXTURE CYCLE START” pushbutton to clamp the workpieces. The “FIXTURE
UNCLAMP” red pilot light goes out. The “FIXTURE CLAMP” green pilot light flashes during
clamping.
9. The “FIXTURE CLAMP” green pilot light remains lit when the workpieces are completely clamped.
The pump will continue to run for 3 seconds after clamping is complete.

Auto-Coupler Control Box
10. After an additional 3 second delay to ensure depressurization of the lines, the pump will start and the
auto-coupler will retract. The “AUTO-COUPLER RET” red pilot light flashes during retraction.
11. As the auto-coupler retracts to disengage the fixture, the “AUTO-COUPLER ADV” green pilot light
and the “FIXTURE CLAMP” green pilot light go out.
12. The pump stops.
13. The “FIXTURE SENSOR” proximity switch senses when the fixture moves out of the load position.
The “AUTO-COUPLER RET” red pilot light is lit to signal that the auto-coupler is ready to receive
another fixture.
NOTE:
Acoupler failure may cause the auto-coupler to retract from the coupled position. This failure is
indicated by flashing of both the “AUTO-COUPLER RET” red pilot light and the “AUTO-
COUPLER ADV” green pilot light. The pump will stop. The auto coupler can be retracted to the
home position by turning the “MAN OFF AUTO” key switch to “OFF.”
The “AUTO-MODE” sequence restarts from the beginning each time “AUTO” is selected on the
“MAN OFF AUTO” key switch, or whenever the power supply is interrupted.
“MANUAL-MODE” sequence of operation
CAUTION: The Manual Mode is intended for system setup only. The pump will run
continuously in this mode. Extended periods in the Manual Mode will cause the
hydraulic fluid to overheat.
1. The base station starts in the home position. The “AUTO-COUPLER RET” red pilot light remains lit
when the auto-coupler is ready to receive a fixture.
2. Turn the “MAN OFF AUTO” key switch to “MAN.” The pump will continue to run.
3. The “FIXTURE SENSOR” proximity switch senses when a fixture moves into the
load position.
4. Press the “AUTO-COUPLER CYCLE START” pushbutton to extend the auto-coupler to engage
the fixture. The “AUTO-COUPLER ADV” green pilot light flashes during extension.
NOTE: The fixture should be in the load position before advancing the auto-coupler.
5. After complete extension the “AUTO-COUPLER RET” red pilot light goes out, and the “AUTO-
COUPLER ADV” green pilot light remains lit.
6. Press the “FIXTURE CYCLE START” pushbutton to unclamp the work pieces in the fixture. The
“FIXTURE UNCLAMP” red pilot light flashes during unclamping.
7. When unclamping is complete, the “FIXTURE UNCLAMP” red pilot light remains lit. After
90 seconds, the valve will shift to the neutral position while the pump continues to run.
8. Remove the completed work pieces from the fixture and place new work pieces into
the fixture.
9. Press the “FIXTURE CYCLE START” pushbutton to clamp work pieces in the fixture. The “FIXTURE
UNCLAMP” red pilot light goes out, and the “FIXTURE CLAMP” green pilot light
flashes during clamping.
10. When the cylinders are completely clamped, the “FIXTURE CLAMP” green pilot light stays lit.
The solenoid remains energized for 3 seconds after clamping is complete. The pump will continue
to run.
11. Press the “AUTO-COUPLER CYCLE START” pushbutton. After an additional 3 second delay to
ensure depressurization of the lines, the auto-coupler will retract. The “AUTO-COUPLER RET” red
pilot light flashes during retraction.
12. As the auto-coupler retracts to disengage the fixture, the “AUTO-COUPLER ADV” green pilot light
and the “FIXTURE CLAMP” green pilot light goes out.
13. When the automatic coupler is fully retracted, the “AUTO-COUPLER RET” red pilot light goes on to
signal that the base station is ready to receive another fixture. The pump will continue to run.
NOTE:
Acoupler failure may cause the auto-coupler to retract from the coupled position. This failure is
