Shut-down periods
During shut-down periods the cleaning cell must be ventilated out (aired out). This
reduces the risk that moister is sucked into gearboxes during cooling down. It
gives the robot the possibility to dry as the rust inhibition effect normally gets
reduced after some time.
Ventilate and air out the cell during and after shut-downs:
• The cell must be ventilated during shut-down until the atmospheric humidity
in the cell has reached the same level as the surrounding environment.
• Will avoid that humid air is trapped into gearboxes or other cavities due to
raised vacuum when cooling down.
• Will give the robot a chance to dry as most rust preventive components in
washing detergents have a decaying effect, i.e. the rust preventive effect is
reduced after a time. Please refer to the Product Specification of the washing
detergent in question for decaying effect. Washing detergent or water without
rust inhibitor can give an accelerated corrosion on some robot components.
• The overpressure must be kept at 0.2 - 0.3 ± 0.0 bar during 24 hours
independent of Motors On/Off mode, start-up and shut down periods
.
