NOTE
Safe Start mode - If the Interlock fault condition clears while units are in the Safe Start mode, the
power supply returns to Output Off mode.
Auto-Restart mode - The output will automatically return to the previous setting.
The following faults will require \ENA_IN recycle: UVP, OVP or Foldback.

3.6.4 Auxiliary Programmed Signals Prog_out_1 and Prog_out_2
The programmed signal Prog_out_1 (J1-21) and Prog_out_2 (J1-20) are open drain, maximum
input voltage 25V and maximum sink current 100mA. Programmed signals can be controlled via
the Front Panel or via communications. Selection of "OFF" via front panel or communication will
result low output signal level and selection of "ON" via front panel or communication will result high
output signal level.
Pin 1 or Pin 2 settings are set as follows:
1. Press the SYST. Button. SYST (GREEN) LED illuminates.
2. Rotate the Voltage encoder until PIN 1 OFF or PIN 2 OFF appears.
3. Rotate Current encoder to select PIN 1 ON or PIN 1 OFF, PIN 2 ON or PIN 2 OFF. Press Current
encoder to accept. The display blinks once to acknowledge the setting.
4. Exit the SYST menu by pressing the Back button or the SYST button.
CAUTION:
Do not connect Prog_out_1 and Prog_out_2 to a voltage source higher than 25V. Always connect
Prog_out_1 and Prog_out_2 to the voltage source with a series resistor to limit the sink current to
less than 100mA.
