∗1: Disconnection detection is a parameter only available for Digital unit (EX600-DXPC1, EX600-DXNC1) with disconnection detection.
∗2: 2-wire type input equipment cannot be correctly detected if its leakage current is 0.5 mA or less while the equipment is in the OFF state
(reed sensor, etc.).
Ensure that all input equipment used has a leakage current above 0.5 mA in the OFF state.
3-wire type input equipment cannot be correctly detected if its current consumption is 0.5mA or less.
The open circuit of input signals cannot be detected.
∗3: The count is memorized every hour. When the power supply is turned on again, counting starts from the last value memorized.
∗4: Times for setting is set value x1000 times.
