Abstract

PURPOSE: To let the terminal control unit and CPU know the intentional cut-off of the power supply by the terminal unit by cutting off the power supply within the terminal unit after informing so to the terminal control unit.
CONSTITUTION: Terminal units 3aW3n are controlled by terminal control unit 2 with individual power source 12 provided. In case units 3aW3n cut off the intra-unit power source 12, they inform so to unit 2 before cutting off the power supply. Thus, unit 2 and CPU identify other faults and can know that units 3aW3n cut off the power supply intentionally.
