Structure

The exact arrangement of the components is shown in the layout diagram in the technical
specifications.
3.4.2

Indicator lights

The four indicator lights H21 to H24 are installed at the top in the door of the open-loop and
closed-loop control cabinet.
3.4.3

Key-operated switch

Use the key-operated switch S11 to select remote control or local operation. The position of the
key-operated switch is evaluated using a TM15 terminal module. With the key-operated switch
position set to "Local", and once the "LOCAL/REMOTE" key has been pressed on the AOP30,
priority for operation is given to the AOP30 or the starter. The AOP30 takes command. In local
operation, the ON command in control word 1 and the main setpoint come from the AOP30 or
the starter.
3.4.4

Fan in the door

A fan with filter is installed in the control cabinet door. The fan is thermostatically controlled and
is switched on when the temperature inside the cabinet reaches approximately 40 °C. The air
is drawn in through the lower door filter and blown out using the fan.
3.4.5

Mushroom pushbutton

The mushroom pushbutton is used for safety shutdown. When the safety shutdown function is
actuated, the converter shuts down with a fault and a corresponding message appears on the
display of the operator panel. Before you restart the converter you must acknowledge the fault.
