|Vacuum Equipment

For ZK2 series vacuum units equipped with an energy-saving function, how do you turn ON the suction command signal?

Refer to the following internal circuits and wiring examples. For NPN, a switch is mounted between gray (FUNC) and blue (minus), and when the switch is turned ON, a suction command signal is output and automatic control is performed.
Note) For PNP, a switch is mounted between gray (FUNC) and brown (plus).

Internal circuit and wiring example 1: NPN output type, NPN open collector 1 output, Max. applied voltage 26.4 V, Max. load current 80 mA, Residual voltage 2 V or less

Internal circuit and wiring example 2: PNP output type, PNP open collector 1 output, Max. load current 80 mA, Residual voltage 2 V or less
