Maintenance
The date and time continue to function even if there is no voltage supply to the unit. The unit has a back-up battery
(CR2032, 3 V) for this purpose. The unit indicates when the battery needs to be replaced (refer to “Replacing the
Battery” on page 45).
All components of the PICO controller are maintenance-free; no regular maintenance is needed. Data and
parameters entered are stored in a non-volatile memory EEPROM/Flash. This memory is normally stored for
approximately 20 years.
Cleaning
Do not use solvents or scouring detergents as this could damage the housing. Do not allow cleaning agents to
penetrate the device!
CAUTION
Clean the external unit housing as needed with a soft cloth, using a mild detergent when necessary.
For interior cleaning of the unit and equipment that comes into contact with fluid during the dispensing sequence,
special cleaning procedures and cleaning agents suited to the product are required. The Clean menu option is used
to activate cleaning of the connected dispensing system by channel. During cleaning, the selected valve opens,
allowing the cleaning fluid to flow through the dispensing system. Refer to “Purging a Valve” on page 41.
Warranty claims become invalid if the unit is opened by unauthorized third parties. Avoid opening the PICO
controller.
