  • Page 4: Introduction

    This works by pre-setting the 7165 pressure to approximately 110 % above the controller line pressure requirement. Once connected, the pump can be started in two button presses to reach the pressure set point.

  • Page 7: Warnings

    THERMAL CUT-OUT SAFETY FEATURE The 7165 is a compressor for use in sealed systems. In cases of the extended periods of use with high air flow and depending on the ambient thermal condition, the compressor can interrupt its operation due to a rise of temperature detected by the safety device.

  • Page 9: Operation

    Before operating the 7165 you should know or clearly define the output pressure that you intend to use the unit to supply. Because the 7165 is a low volume system, it is not ideally suited for use with regulators that self-relieve and vent constantly. With such systems the compressor setpoint will not stabilise and there will be a constant requirement for the pump to pressurise against the repeated pressure release of the regulator.

  • Page 10: Operating Modes

    This mode is indicated by the led LD1 (green) on. Start-up Procedure Warning: The 7165 should be connected to the pressure controller or device it will supply pressure to, with all fittings and hoses securely tightened and checked.
  • Page 11 Time Electronics 7165 High Pressure Compressor User Manual At this stage, the keys have the following functions: Function Starts automatic control mode ENTER Starts editing the setpoint DOWN Starts editing the setpoint If the setpoint shown is the desired value, simply press the ENTER key to start the automatic control mode (LD1 green on, compressor enabled).

  • Page 12: Pressure Setpoint Editing

    Time Electronics 7165 High Pressure Compressor User Manual Pressure Setpoint Editing When in automatic control mode, to enter configuration mode simply press the ENTER key. Pressing the ENTER key, the SP (setpoint) is displayed. To edit it, press the UP or DOWN key. At the edit level, the keys have the following functions:...

  • Page 13: Configuration Menu

    User Manual Configuration Menu The 7165 has a configuration menu where you can edit the hysteresis parameter, select the pressure unit, and perform the VENT (pressure relief) function. To access this menu, press the ENTER key for more than 5 seconds.
  • Page 14 To edit it, enter the 7165 setup menu by pressing the ENTER key for more than 5 seconds, select the "HYST" option, press the ENTER key and edit the desired value.
  • Page 15 The 7165 vents internal to the case so no pressure is exhausted externally. 5.6.3 Pressure Units The 7165 is set at the factory with the pressure unit "bar". However, the pressure unit can be changed. To select the pressure unit, access the 7165 setup menu by pressing the ENTER key for more than 5 seconds, select the desired unit (psi, bar, or kgf/cm²), and press ENTER.

  • Page 16: Calbench Installations

    For customers who have purchased the 7165 with a Time Electronics CalBench system, the unit will be supplied with all the necessary hoses and fittings for usage. The 7165 can be situated near or far from the bench with the length of hose and RS-232 cable supplied to meet this requirement.

  • Page 17: Virtual Control Software

    Virtual Control Software RS-232 Connection The 7165 is fitted with an RS-232 port on the rear of the unit. This can be connected to a PC or laptop to run the virtual control software application. Note: For customers who have ordered the 7165 with a CalBench system featuring a control centre PC module, the software will be pre-loaded and configured for use.

    You can now press the “Control” button to output the set pressure. Note: If you change the set pressure whilst the 7165 is already in control mode, the output pressure will instantly adjust to the new setting. Be careful not to over-pressurize the controller or unit receiving pressure.

  • Page 20: Setting And Changing A Hysteresis Value

    1, 2, 3, 4 bar. It is the amount of pressure you let the 7165 drop by before the pump re-starts to pressurize to the setpoint. To set a hysteresis value double click on the Hysteresis input box.

  • Page 21: Setting And Changing The Pressure Unit

    To change pressure units press the Unit button. Then select a new pressure unit from the drop-down menu. There are 3 pressure units available on the 7165, as shown above. Once selected, press the “Change” button to apply the new pressure unit.

  • Page 22: Controlling And Venting

    The control and vent buttons are situated on the right side of the display. When the 7165 is switched on it performed a vent automatically. So when connecting to the unit via the control application you should be starting in a vented state. The output pressure will display approximately 0.0 (or 0.1 as shown below).
  • Page 23 IMPORTANT NOTE: Ensure you vent the 7165 after daily use or after the required workload is completed. It should not be left pressurized for prolonged periods. This is for safety to ensure that no pressure remains in the supply line or...
