The controllers of the THQ series are characterised by remarkable regulation precision, in particular in heat-sealing and thermoforming operations typical of the automatic packaging.
The AT initial autotuning and the ADT permanent autoadaptive functions can both be activated through the PID control action, responding excellently to requent or fast system variations, as for example in process start and stop.
The panel with single or double display allows the setting of all the controller’s values and configurations, such as sensor input, control action and alarm functions, with the possibility to lock the programming on three different safety levels.
The exclusive LFA diagnostic function is able to detect failures along the entire regulation loop, for example thermocouples short-circuit or heating resistance
