Operation
Operating the HPU Locally or Remotely
The HPU can be operated locally using the front panel controls or remotely using
your system controller.
Local operation
1. Make a general inspection of the HPU. Ensure that all cooling water valves
are open and that the external hydraulic circuit is ready for pressure to be
applied. Ensure that the Stop button is released.
2. Turn the start switch to the Start position until the pump motor starts. When
the switch is released, it will return to the Low position.
3. Check the HPU for leaks and unusual sounds. Stop the HPU immediately if
leaks or unusual sounds are noticed. Determine the cause and fix the
problem before restarting the HPU.
4. Turn the start switch to the High position to operate the HPU at full
pressure.
Note If the HPU generates an interlock during operation (low fluid level or
high temperature), the HPU will be stopped. Once the cause has
been corrected, press the Reset button before restarting.
5. To stop the HPU, press the red Stop button.
Remote operation
Remote operation of the HPU can occur at a remote control panel or from your
system controller software. The controller must be connected to the HPU.
Note MTS controllers can issue the off, low, and high signals to the HPU to
control the hydraulic pressure.
This procedure requires the controller to be connected to the HPU.
1. Make a general inspection of the HPU.
A. Ensure that all cooling water valves are open and that the external
hydraulic circuit is ready for pressure to be applied.
B. Ensure the Stop button is released.
2. Start the HPU at your controller.
3. Check the HPU for leaks and unusual sounds. Stop the HPU immediately if
leaks or unusual sounds are noticed. Determine the cause and fix the
problem before restarting the HPU.
4. Select high pressure at your controller.
Note If the HPU generates an interlock during operation (low fluid level or
high temperature), the HPU will be stopped. Once the cause has
been corrected, press the Reset button before restarting.
5. Stop the HPU with the controller.
