The ELSD contains an internal timer to initiate the time-based events stored within the timetable. To start the internal timer and trigger the on-board timetable, a contact closure input via the I/O connector on the rear of the instrument is required (see Overview of ELS Detector).
When the on-board timetable is triggered, the front panel of the ELSD will display TTRUN above the output, as shown in ELSD front panel display during timetable operation.
When the timetable is running, the current and the total run time are displayed, in minutes, at the top-centre of the ELSD display. When the timetable reaches the end of its run time, the ELSD will revert to RUN mode and be primed ready to start the timetable again.
During an active timetable, where the evaporator temperature is being controlled, the status of the instrument will change from READY to NOT READY. This behavior is normal band will not affect the running of the timetable.
