Programmer level (PGM)
The programmer function of the units permits storage of 5 temperature-time programmes. Each
programme
consists of several temperature-time segments. In addition there is the information how
many times the programme should be run (
LOOP
). The total number of all the segments of all
programmes must not exceed 150.
A segment is normally a
ramp
which is defined by the target temperature, i.e. the temperature at the
end of the segment, and the duration from the start to the end of the segment.
It is possible to have
temperature steps
, i.e. the time is zero, and also
temperature hold phases
,
i.e. the same temperature at the start and at the end of a segment.
At the start of the programme the current actual temperature is taken as the start temperature of the
first segment.
It is recommended to adjust the setpoint to a defined value before the start of the
programme, and to terminate the programme at the same temperature.
The programmer can also be operated or modified via the RS 232.
