10.5 USER INPUT FUNCTIONS 10.5.1 DESCRIPTION

• Initiate a trip and a reclosure (760 Only).
• Log the operation of a contact in the event recorder.
• Convert an external contact into a self-resetting, latched or pulsed contact.
• Convert an external contact into a form-C contact.
• Provide a contact multiplier for an external contact by operating multiple relays.
