Flankgetriggerde Wisrelais

Provides a fixed number of adjustable pulses at the output for every pulse on the input Tr.

INFORMATION

The edge-triggered wiping relay allows a rising edge at the input Tr to generate a set number of pulses at the output Q. The parameter TH defines the on duration of the pulse and the parameter TL defines the off duration. The parameter N is the number of pulses for each rising edge at Tr. Every time Tr is triggered the timer of the pulses is reset and begins counting again.

If the input R is triggered, the timer is reset and the output Q is disabled, and only if Tr is triggered is the timer started again.

The block can be set to be retentive, this is done by clicking on the battery symbol tl_files/loxone/documentation/EN-UK/function_blocks/Untitled.png to set the red NOT dot on the block (input is by default inactive).
