State LEDs

In case of overload or short-circuit, the outputs switch off automatically and try to switch on again cyclically. Therefore, an acknowledgement of the outputs is not necessary.

LED	State	Color	LED = OFF	LED = ON
Inputs/ outputs C0…C7	Digital input or digital output	Yellow	Input/output = OFF	Input/output = ON (the input voltage is even displayed if the supply voltage is OFF).
UP	Process voltage 24 VDC via terminal	Green	Process voltage is missing	Process supply voltage OK and initialization terminated
CH-ERR1	Module Error	Red	No error	Error
