Circuit Configuration
• When an overcurrent is detected, the ERR indicator will light. At the same time, the corre-
sponding bit in the Basic I/O Unit Information Area system-defined variable will change to
TRUE.
External connection and terminal-
device variable diagram
• When wiring, pay careful attention to the polarity of the external power supply. The load may
operate incorrectly if the polarity is reversed.
