Programmer/Controller General Description
The programmable controller contains an in-built setpoint generator in addition to the
controller function. This setpoint generator can produce a temperature/time profile with
10*16 segments (0
9
10 Sets of Curves). When the program is running, the current setpoint
from the setpoint generator is fed to the control algorithm. The current setpoint is
continuously shown on the lower display.
The sixteen segments are defined in the order: Ramp 1, Dwell period 1, Ramp 2, Dwell
period 2..., and are executed in succession.
