Obsolete KS 94 Single Loop Temperature Controller
KS 94
The KS 94 single loop controller is configurable for ON/OFF control, PID control and motorised valve control. The output function can be configured for ?/Y/Off, position control, split-range control, and numerous 3-point combinations of switching/continuous control.
Control modes are set-point, set-point/cascade, and programmer, each with the possibility of setpoint offset. The effect of offset can be additive e.g. reduced standby set-point or as a factor e.g. O2 correction or split load. Offset can be triggered by an external contact, whereby the value is defined via an analog signal or via an adjustable parameter.
Feed-forward control is very useful to line out disturbances, e.g. with steam-generating plants.
For applications where several controllers act on a single actuator, the override control function is recommended.
