Wiring color
■ Polarity switch POL is used to switch the polarity (NPN/PNP) of the sensor connected to the transmission unit.
Check the wiring diagram, and wire it according to the sensor to be connected. If it is not wired, no signal will be detected.
■ When shipped from the factory, the unused core wire of the cable is cut. If the cable is shortened for wiring reasons, the unused
core wire will be exposed. If you shorten the cable for wiring reasons, the unused core wire will be exposed, so please take care
not to short-circuit the cable. Unused wires are as follows: Cable 1: Green*, Blue*, Purple*.
Cable 2: brown*, red*, orange*, yellow*, white, empty. (* indicates a wire with ■ ■ or ** printed on the core wire of each color.)

*When connecting DC 2-wire sensors, wire a resistor with a resistance value of 3 to 4 k Ω and a rated power of 1/2 W or more.
The resistance value can be calculated by the following formula. To operate properly, select a resistance value smaller than the caluculated value.
Resistance value [ Ω ]
≤
(Output voltage lower limit 22.5 [V] - Sensor residual voltage [V]) / Sensor minimum load current [A]
Protective function
The explanation about the built-in protection function is as follows.
Reverse connection protection・・・This function protects the circuit by preventing current from flowing to the internal circuit when +24V and 0V are connected
in reverse on the power supply line of the base.
Overheat protection ・・・This function measures the temperature inside the Base part and stops the power supply when a certain temperature is
exceeded. It will restart when the temperature drops.
Short-circuit protection ・・・This function protects the circuit by turning off the output for a certain period of time when a current exceeding the specifications
flows through the signal output line due to unloaded wiring.
Overcurrent protection ・・・A function that protects the circuit by detecting the current inside the Base part and stopping transmission for a certain period of
time when a certain current value is exceeded.
Output surge absorption protection・・・ A surge absorption circuit is built in to protect the output circuit.
Metal facing protection of the head・・・ When metal is detected, transmission is stopped for a certain period of time to protect the circuit.
