Fields of applications are, for example, extruders, injection moulding machines, tempering devices and hot runner systems. The high-contrast, multi-colour LCD display for actual value, setpoints and operator guidanceconsists of two four-digit indications of 7 segments, two one-digit indications of 16 segments, indication of the active setpoints, sixswitch position indicationsandindication for unit, ramp function and manual operation.
Simple operation via four buttons. The devices can be applied as two-point, three-point-, three-point step controllerorcontinuouscontrollers. The software of the controller consists, among other things, of a hot runner start-up ramp function, monitoring of closed-loop control and output, two self-optimisation procedures, one mathematic and logic module as well as 4 limit value controls. The linearization of the usual transducers is stored; a customer-specificlinearization table can be programmed.
For the comfortable configuration via PC, a setup programme can be supplied. Via an interface RS422/485, PROFIBUS-DP orcurrent interface it is possible to integrate the devices into a data network. The electric connection is realized on the back via screw terminals. The option boardscan be applied universally for the whole device series.
