application.
TGOFF Delay Generator switching off delay after closure of line LN1 CB1.
Delay in activation of outlet DO7, after detection of the fault
TL Delay
on both lines LN1 and LN2.

ATTENTION: it is necessary to take into consideration that the total switching time, in addition to the set
up delay, includes also the internal time of ATS.
