The REVO HMI can display four or eight loop pages, which feature a zone description that can be edited by the user, on-off pushbutton, set-point display and setting, temperature measured display, power output value, generic alarm status, deviation graph and trend display push button for each zone.
Each loop can have a dedicated trend page that provides a graphical time display of set-point value and temperature control response. A 15 minute log can be shown at any one time on a maximum of 24 operating pages, including four graphical displays.
Control parameters include proportional band, integral time, derivative time, cooling gain, overlap for proportional band, pre-tune activation and self-tune activation.
