Page 20: Operation Of The Econtrol 8611
The eCONTROL 8611 must only be used by qualified personnel. Display elements The eCONTROL 8611 is equipped with an operating and display element with keys and LCD matrix display. The function of the keys is described in the following chapters.
Page 21: Operating States
operating states Three operating states are possible during operation of the eCONTROL 8611: • Operating mode • Configuration mode • Autoscaling mode When the supply voltage is switched on, the software version of the control- ler appears on the display for approx. 2 seconds. The controller is then in operating mode.
