Electrics • Electrical connections are to be wired up or disconnected only when power is disconnected! • Use only low voltages of up to 24 V DC. Pneumatics • Do not exceed the permissible pressure of 8 bar (800 kPA). • Do not switch on compressed air until you have established and secured all tubing connections. • Do not disconnect air lines under pressure. • Particular care is to be taken when switching on the compressed air. Cylinders may advance or retract as soon as the compressed air is switched on. Mechanics • Securely mount all components on the plate. • No manual intervention unless the machine is at rest. • The pump can be mounted horizontally or vertically. If mounted, the output of the pump must point upwards. The pump must be mounted so that is flooded (see also data sheet). © Festo Didactic GmbH & Co. • FluidLab-PA Software 11 close valves) before you make changes at the piping system. ensures a prolonged maintenance-free operation of the system (proportional valve and pump).5 bar. • Fluid Lab®–PA Software . • Do not operate the pump without fluid. piping. • It is possible to drain the fluids inside the FluidLab® PA by opening hand valve V105 12 © Festo Didactic GmbH & Co. • Do not operate the heating unit unless the heating element is fully immersed in fluid. • The maximum operating temperature of the tanks must not exceed +65 °C. running dry or used for sea water or contaminated fluids.Notes on safety Process engineering • Before filling the tanks with water switch of power supply!
