 Cautions for Connection of Dual Input Signals
• Connect the switch (contact) that turns the dual signals ON and
OFF simultaneously.
• If the timing that turns the two signals ON and OFF is not right, a
disagreement alarm occurs. Refer to the figure below.
• Do not connect two signals to the same contact point.
(Prepare two individual contact points)
• Since the power supply for each signal is reversed, it will short-
circuit and may cause breakdown of DX200 Unit if the signals are
connected to the same contact point.
