5.3 Automatic Dwell Mode Operation

The Dwell Mode feature allows the pump to react automatically at two user-defined pressure values, “PRESR A” and “PRESR B”. This feature can be turned on and off as desired. See the following paragraphs for additional information. Also refer to Section 6.2 for detailed Dwell Mode operation and setting instructions.

1. Dwell Mode Off

The pump LCD control panel will display pressure as a simple pressure gauge. No additional actions will be performed regardless of PRESR A and PRESR B values.

2. Dwell Mode On

The pump will automatically de-energize the motor and valve solenoid after the specified PRESR A or PRESR B value is reached AND the specified dwell time (in seconds) has elapsed. When the pump stops, pressure in hoses will drop to zero (0) so that couplers can be disconnected from the pallet.

Note: “AUTO” is shown on the LCD screen when Dwell Mode is turned-on. “READY” is shown when Dwell Mode is turned-off.

5.3.1 Overview of Dwell Mode

Before the PRESR A or PRESR B value is reached:

• Pendant Up-Arrow and Down-Arrow buttons will function as described in Section 5.1.

After the PRESR A or PRESR B value is reached:

• Continuing to press and hold the Up or Down Arrow

button after the specified pressure value is reached will activate the dwell timer. The LCD screen backlight will begin flashing, and the pump will continue running until the user-defined dwell time (1 to 60 seconds) has elapsed.

• To ensure proper clamping and unclamping, the Up or

Down Arrow button must remain depressed until the pump stops.

• Releasing the Up or Down Arrow button will stop the

automatic cycle, and the LCD screen backlight will stop flashing.

• If dwell time is set to zero (0), the pump will stop

immediately when the specified pressure value (PRESR A

or PRESR B) is reached. Restarting the Automatic Cycle: Releasing and depressing the pendant Up-Arrow or Down-

Arrow button will restart the automatic cycle.

IMPORTANT: relief valve pressure setting. When Dwell Mode is ON and pendant Up or Down Arrow button is depressed, pressure will continue to rise to the relief valve setting even after the specified pressure value (PRESR A or PRESR B) when using Dwell Mode, be certain that the PRESR A and PRESR B values are set at least 200 psi [13,7 bar] BELOW the relief valve pressure setting.

Frequently inspect all system components for leaks or damage. Repair or replace damaged components. Electrical components, for example, the power-cord, may only be repaired or replaced by a qualified electrician, adhering to all applicable local and national codes.

7.1 Check Oil Level

Check the pump oil level prior to start-up. If oil level is low, remove the SAE #10 plug from the fill pipe extension and add oil as needed (see figures 2 and 4). Always be sure cylinders are fully retracted before adding oil to the reservoir.

7.2 Change Oil and Clean Reservoir

Enerpac HF oil is a crisp blue color. Frequently check oil condition for contamination by comparing pump oil to new Enerpac oil. As a general rule, completely drain and clean the reservoir every 250 hours, or more frequently if used in dirty environments.

Note: This procedure requires that you remove the pump from the reservoir. Work on a clean bench and dispose of used oil according to local codes.

1. Remove the drain plug and drain all oil from the reservoir. Clean and reinstall the drain plug.

2. Unscrew the 13 bolts holding the cover plate to the reservoir and lift the pump unit out of the reservoir. Be careful not to damage the filter screen.

3. Thoroughly clean the reservoir and reservoir magnet (if equipped) with a suitable cleaning agent.

4. Remove the pick-up filter screen for cleaning. (Do not pull on the screen or the bottom of the intake to avoid possible damage.) Clean the screen with solvent and a soft brush. Reinstall.

5. Reassemble the pump and reservoir, installing a new reservoir gasket.

6. Fill the reservoir with clean Enerpac hydraulic oil. The reservoir is full when oil level is as shown in Figure 4.

7.3 Changing the Filter Element (optional)

A return line filter may be ordered as an accessory to the pump. The filter element should be replaced every 250 hours, or more frequently in dirty environments. The filter manifold is equipped with a 25 psi (1.7 bar) bypass to prevent over pressure rupture if filter plugging occurs. Filter element replacement part number is PF25.
