Operate the HPU Locally or Remotely
Local Operation
The HPU can be operated locally using the controls on the user interface panel.
1. Make a general inspection of the HPU. Ensure that all cooling water valves are open. Ensure the
Emergency Stop button is released.
2. If not already displayed, press the Main button to display the Main screen.
3. Verify that the Remote Operation button is gray. If the button is green, press the button to change it to
gray (indicating local mode).
4. Verify that at least one pump is enabled. Enable additional pumps as necessary.
5. Press Run to start the pumps. The pumps start sequentially to prevent an electrical overload. Each pump
starts in low pressure mode.
6. Check the HPU for leaks and unusual sounds. Stop the HPU immediately if leaks or unusual sounds are
noted. Determine the cause and fix the problem before restarting the HPU.
7. Press High Pressure to turn on high hydraulic pressure.
Note:
If the HPU generates an interlock during operation (such as low fluid level or high temperature),
the HPU will stop. Once the cause has been corrected, press the Reset button before restarting.
8. Run the HPU for about 30 minutes or until the hydraulic fluid is up to operating temperature [typically
43–49°C (110–120°F)] before using your test system.
9. When in high pressure mode, press the High Pressure button to return to low pressure mode.
10. To stop the HPU, press the Stop button.
Remote Operation
Remote operation can occur at a remote control panel or from your system controller. The controller must be
connected to the HPU.
