IMPORTANT:
The CYLINDER CONTROL VALVE (SLCV-24)
has a manual override capability. The valve is NORMALLY
CLOSED and can be manually opened by depressing the pin
located in the center of the valve coil. The valve will remain open
when the pin is depressed and will return to the closed position
when the pin is released. (Refer to Figure 4.)
9.0 ELECTRICAL COMPONENT ASSEMBLY
It is helpful to mark all cable connections and hose ends with
some sort of identifying feature for simple assembly and trouble-
shooting. Colored electrical tape is a good choice.
1.
Swing open the cover from the SLCG-8 CONTROLLER and
make sure the power switch is in the
OFF
position.
2.
Depress the EMERGENCY STOP button and rotate clockwise
to ensure that it is deactivated.
3.
Connect the power cord to the CONTROLLER. The power
cord plugs into the three-pin plug on the face of the
CONTROLLER (Figure 2).
Note:
The SLCG-8 CONTROLLER requires 115/230VAC
single-phase power to operate.
4.
Connect the dual DIN plug electrical cable (SLPVC-1) from
the DIRECTIONAL CONTROL VALVE to the output plug on
face panel of the CONTROLLER (Refer to Figure 3, Basic 4-
Point Setup drawing.)
5.
Connect the CYLINDER CONTROL VALVES to the controller
outputs marked VALVES. You only need to connect as many
valves as you plan to use. If you use four valves, connect
them to valve connection points 1-4 and so on.
6. Place an SLSS SENSOR at each lift point. Connect an SLSC-
15 SENSOR CABLE between the SENSOR and the
CONTROLLER. The SENSOR placed at lift point No. 1 must
be connected to sensor input plug No. 1 on the front panel of
the CONTROLLER; repeat this procedure for all remaining lift
points.
NOTE:
SLEC-15 and SLVEC-15 EXTENSION CABLES can be
used to reach jack placement greater than 50 feet. Contact
Enerpac for more details.
WARNING:
The matching of sensor and valve wiring is
essential to synchronous lifting. Failure to do so may
result in unexpected lift behavior. Always test the
control function of each cylinder individually prior to positioning
under the load.

SYSTEM POWER UP AND CONTROL VERIFICATION
This set-up procedure should be completed in its entirety with
the PUMP TURNED OFF.
POWER CABLE
1.
Plug power cable from the CONTROLLER into 115/230VAC.
2.
Depress the EMERGENCY STOP button and rotate clockwise
to ensure that it is deactivated.
3.
Turn CONTROLLER power switch on. The following screen
should appear showing Preferences and System Setup.
