    Setting Up Fault/Inhibit System Protection To set up Fault/Inhibit system protection, an OVL sense cable is required. Refer to the following sections: • Digital Control Port • What is Being Connected in ICT? Table 1-5 OVL sense cable Part number Description 03066-61623 OVL sense cable, 67xx DUT power supply...

  • Page 24: Digital Control Port

    Digital Control Port An 8-pin connector and a quick-disconnect connector plug are provided for accessing the digital control port functions. The digital control connector accepts wires sizes from AWG 14 to AWG 30. Note that wire sizes smaller than AWG 24 are not recommended. Disconnect the connector plug to make your wire connections.

  • Page 25: What Is Being Connected In Ict

    What is Being Connected in ICT? • Fault Output • Inhibit Input • Fault/Inhibit System Protection • Clearing a System Protection Fault Fault Output Pins 1 and 2 can be configured as a fault-output pair. The polarity of pin 1 can also be configured.
  • Page 26 Inhibit Input Pin 3 can be configured as a remote inhibit input. The polarity of pin 3 can also be configured. Pin 8 is the common for pin 3. The Inhibit Input function lets an external input signal control the output state of all the output channels in the DUT power supply.
  • Page 27 Fault/Inhibit System Protection The following figure illustrates some ways that you can connect the Fault/Inhibit pins of the connector. As shown above, when the Fault outputs and Inhibit inputs of several DUT power supplies are daisy-chained, an internal fault condition in one of the DUT power supplies will disable all of them without intervention by either the controller or external circuitry.

  • Page 36: Replacing A Power Module

    Replacing a Power Module Turn the DUT power supply off and disconnect the power cable before removing and installing power modules. Observe all standard electrostatic discharge precautions before handling electronic components. Always replace a power module with the same model, otherwise the DUT power supply cannot be controlled by the i3070 In-Circuit Test Software.
  • Page 37 Align the new power module over the pins and push it down onto the connector. Secure with the screws at each end of the power module. Because the RFI strips apply upward pressure, continue pushing down on the module until the screws are tight.

  • Page 38: Replacing Connectors On Old Output Cables

    Replacing Connectors on Old Output Cables The output cables from some older i3070 systems can be used with the N67xx DUT power supplies by cutting off the lugs and rewiring them based on the diagrams in Connecting the Output Cables. Note that the labels on new output cables are different from the old cables, and the wiring information in this chapter refer to the new labels.
