Manual Operations

Manual Mode options

The DEMI 400 Series can be operated in a completely manual mode. It is important to keep in mind that the configured AUTO modes are all optimized for the most efficient operation. However, manual mode may be preferred when an operator is experimenting with new geometries or parameters. From the Home screen, press the MANUAL button to access the Manual Run screen.

Manual Run Mode

The buttons along the bottom of the screen control the available energy sources of the DEMI 400 Series. Any function that is active will be highlighted blue. Press the respective button to turn off, which will become greyed out. Below, the functions are explained in detail.

• TEMPERATURE INPUT – Set a temperature limit for the liquid detergent in the DEMI 400 Series. The current average tank temperature is displayed in black.
• ULTRASONICS – Turn ultrasonics agitation in the DEMI 400 Series on and off. Note the ultrasonics do generate heat.
• PUMP – Turn the DEMI 400 Series system pump on and off.
• COOLING FAN – Turn on the fans in the cabinet below the tank to keep the DEMI 400 Series processing tank at the desired temperature. In Auto Run Mode, the software will turn the fans on automatically to perform this function.
• HEATER – If operating in Manual Mode, the HEATER button must be turned on to allow the detergent in the tank to heat up to the temperature setpoint.

*When the ultrasonics agitation is enabled, the heater button is automatically turned off. The heater and ultrasonics cannot be enabled at the same time.
