Representation Representation on the screen is as follows:
Outputs The digital signals can be used to operate three relays (extra code). The action
can be configured as a break (SPST-NC) or make (SPST-NO) contact
(Configuration ➔ Outputs).
External texts External texts can be called up via four binary inputs or the logic channels. If a
binary input is closed or a logic channel makes a 0-1 transition, then the
preconfigured text will be entered in the event list. Either a standard text or one
of the 18 definable texts can be used. The instrument automatically
supplements the texts in order to distinguish between the appearance and
disappearance of the signal. The external texts are configured on the
instrument, under Configuration ➔ Control functions.
v Chapter 3.5 “Event list”
Event operation The digital signals can be used to activate event operation. In event operation,
the measurements are stored with a storage cycle that is different from normal
operation.
2.5 Counters / integrators / operating time counter
These are not electrical measurement inputs (hardware), but channels which
are calculated by the paperless recorder (software).
