Operator Station
To allow an operator to start, stop, and monitor the process, an operator station is also required.
The operator station is equipped with the following:
• Switches for controlling the most important stages of the process. Using the "reset
maintenance display" switch, you can turn off the maintenance display lamps for the motors
due for maintenance and reset the corresponding counters for the maintenance interval to 0.
• Display lamps to indicate the status of the process.
• The emergency stop switch.
