7.10 Programmer (PGM only Command)
Almost any temperature/time profile can be created with the programmer. A desired bath temperature
can be approached as quickly as possible or via a defined ramp. Furthermore, the pump level and the
behavior of the switching outputs can be defined. Five temperature/time programs are provided for free
programming. Each program consists of a number of temperature/time segments. Also included are
details of how often the program is to be executed (loops). The sum of all segments of all programs
may be up to a maximum of 150. Typical segments are:
Ramp:
If a time is specified, then the segment is a ramp, which is described 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.
Step:
Without any specified time the final temperature is approached as quickly as possible.
Temperature hold phase:
No temperature change (i.e. the temperatures at the start and end of a
segment are the same).
The programmer can be controlled or changed via the RS 232 interface, the timer or
switching contacts.
