Table 5-5: Interlock functions and settings

CAUTION: To prevent possible damage to the unit, do not connect any of the Enable /Disable inputs to the positive or negative output potential. NOTE: Safe Start mode - If the Interlock fault condition clears while units are in safe start mode, the power supply stay to Off mode. Auto Restart mode - The output will automatically return to previous settings. 5.7.3 Auxiliary Programmed Function Pin 1 and Pin 2 The programmed signal Pin 1 (J3-1) and Pin 2 (J3-6) are open collector, maximum input voltage 25V and maximum sink current 100mA, and can be controlled via Front panel or software. Pin 1 or Pin 2 settings are made as follows: 1. Press MENU button. MENU (GREEN) LED illuminates. The ” . ” message appears on the Current display. 2. Press Current encoder and the ”  ” message appears on the Voltage display. 3. Rotate Voltage encoder until ” Pin1 / Pin2 ” message appears on display. Press Encoder to select the desired Pin. 4. Voltage display shows the selected Pin number. 5. Rotate the Current encoder to toggle between ” Hi ” (High) or ” Lo ” (Low). 6. Press Current encoder to select desired parameter. 7. Press MENU button twice to return display to it’s previous state. MENU LED turns OFF.

CAUTION: Do not connect Pin 1 and Pin 2 to a voltage source higher than 25V. Always connect Pin 1 and Pin 2 to the voltage source with a series resistor to limit the sink current to less than 100mA.
