• General-Purpose Input (DIN) level must be 1.5 seconds or longer to be detected.
It may not detect under 1.5 seconds.
• Be sure the voltage value between terminals is controlled via the input voltage, so
that the PL is operated within its recommended range. If the input voltage
exceeds this range, a malfunction or PL damage may occur.
• With Sink/Source input, even if the DIN(-), and RESET(-) are positive, and
DIN(+), RESET(+) are negative, no problems are created. Be sure to operate the
unit within the recommended voltage range.
