• General-Purpose Input (DIN) level must be 1.5 seconds or longer to be
detected.It may detect under 1.5 seconds.
• Be sure the voltage value between terminals is controlled via the input voltage, so
that the PS-A is operated within its recommended range. If the input voltage
exceeds this range, a malfunction or PS-A damage may occur.
• With Sink/Source input, even if the DIN(-), and RST(-) are positive, and DIN(+),
RST(+) are negative, no problems are created. Be sure to operate the unit within
the recommended voltage range.
