3.11 GPI
Option G must be installed. The settings of this submenu are used for operation with a relay
which may be triggered at a programmed time. A “GPI“ (General Purpose Interface) is a
switching relay. The contacts between COM1and NO1 are normally open, or closed when
triggered, and normally closed between COM1and NC1, or open when triggered,
respectively. Switching is performed pulse-like after triggering. The pulse, i.e. trigger duration
is adjustable between about 64 ms - 1.28 s (+0 / -20 ms). Triggering is performed, when the
GPI is active and a pre-set comparative time information value is detected by the LTC
generator or one of the timer times out of A, B, C, D, E or F.
