2.12.1 Interlock Function - Analog On/Off (Enable/Disable)
Interlock signal (\ILC_IN) serves as power supply output enable control via a switch or relay.
Use the Interlock function to enable or disable the output as emergency shutoff or door open
switch. It is an isolated signal from the power supply output. Connection to the signal is made via
pin J1-19 (\ILC_IN) and pin J1-11 (COM_SELV).
The ILC function can be enabled or disabled via communications or the Front panel as follows:
1. Press the SYST button. SYST (GREEN) LED illuminates.
2. Rotate the Voltage encoder until ILC OFF appears.
3. Rotate Current encoder to select ILC ON or ILC OFF. Press Current encoder to accept. The
display blinks once to acknowledge the setting.
4. Exit SYST menu by pressing the Back button or the SYST button.

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 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 \ILC_IN recycle: UVP, OVP or Foldback.
