5.2. Drive Unit Control Overview
Note
: The drive unit enclosure is sealed for water/spray resistance (IP23). The control panel is
splash resistant (IP65).
External electrical connections are done with cables running along the frame.
The controls are located on the face panel of the control box (Figure 6). They are: Operator
Touchscreen Interface, Quick Adjustment Keys, Power Button, and Emergency Stop push button.
Other options including those for remote control through connectors are available on the bottom
panel of the control box as shown in Figure 7.
Most control functionality is provided to the user through the touchscreen interface including
activation of functions, display of process information and alarm status. The magnetic mixer can
be operated in one of three modes selected by the operator locally from the main menu screen:
•
Manual mode of operation
•
Automatic mode of operation
•
Remote mode of operation
Each mode includes a specific set of functions to support processing requirements.
Additionally, there is locked mode of operation which represents variation of remote control from
an external system and is intended to support control of the mixer using other equipment such as
Pall MVP system.
