﻿This is where the 2-channel operation concept is defined.

*Channel 1 or channel 2*: With this operating concept, exactly one telegram is sent each time the contact closes. The time duration for distinguishing between a short and a long signal is determined by the parameter "Time between channel 1 and channel 2". If the signal is shorter than the parameterised time, only the telegram to channel 1 is sent when the contact is opened. If the signal is longer, only the telegram to channel 2 is sent after time has elapsed. This concept provides the transmission of only one channel.

*Channel 1 and channel 2*: With this operating concept, either only one or alternatively two telegrams are sent each time the contact closes. The time duration for distinguishing between a short and a long signal is determined by the parameter "Time between channel 1 and channel 2". When the contact is closed, the telegram for channel 1 is sent immediately. If the signal lasts longer than the set time, the telegram for the second channel is also sent immediately after the time has expired. If the contact at the input is released before the time has elapsed, the device does not send a telegram for channel 2.
