5Work and safety instructions
5.1 General remarks
•Trainees should work with the circuits only under the supervision of an instructor.
•Electrical devices (e.g. power supply units, compressors and hydraulic power units) may only be
operated in training rooms which are equipped with residual current devices (RCDs).
•Observe specifications included in the technical data for the individual components, and in particular all
safety instructions!
•Malfunctions which might impair safety must not be generated when the device is operated for training
purposes.
•Wear your personal protective equipment (safety goggles, safety shoes) when working on the circuits.
5.2 Mechanical system
•Switch off the power supply.
– Switch off both the working power and control power before working on the circuit.
– Only reach into the setup when it is at a complete standstill.
– Be aware of potential overtravel times of actuators.
•Mount all of the components securely on the profile plate.
•Make sure limit switches are not operated from the front.
•Risk of injury during troubleshooting.
Use a tool to operate the limit switches, for example a screwdriver.
•Set all components up so that it’s easy to activate the switches and interrupters.
•Follow the instructions regarding positioning of the components.

5.3 Electrical system
•Risk of fatal injury in case of interrupted PE conductor!
– The protective conductor (yellow-green) must not be interrupted, either inside or
outside of the device.
– The insulation of the protective conductor must never be damaged or removed.
•Risk of death from series connection of power supply units!
Contact voltages of greater than 25 V AC or 60 V DC are not permissible.
Coming into contact with voltages of greater than 50 V AC or 120 V DC may be fatal.
– Do not connect voltage sources in series.
•Risk of death due to electric shock!
Protect the outputs of the power supply units (output sockets/terminals) and cables connected to them
from direct contact.
– Only use cables with adequate insulation and electric strength.
– Use safety sockets with fully shrouded contact points.
•Disconnect from all sources of electric power!
– Switch off the power supply before working on the circuit.
– Please note that electrical energy may be stored in individual components.
Information on this issue is available in the datasheets and operating instructions included
with the components.
–Caution!
Capacitors inside the device may still be charged even after being
disconnected from all sources of voltage.
•Devices with a grounding terminal must always be grounded.
– If a ground connection (green/yellow laboratory socket) is available, it must always be connected
to protective ground. The protective grounding must always be connected first (before voltage) and
disconnected last (after voltage).
– Some devices have high leakage current. These devices must be additionally grounded with
a protective earth conductor.
•Use safety extra-low voltages only: max. 24 V DC.
•The power supply unit must be operated only with a power supply with a grounding conductor.
•Establishing and disconnecting electrical connections
– Electrical connections may be established only in the absence of voltage.
– Electrical connections may be disconnected only in the absence of voltage.

Mixing Learning System Work and safety instructions

•Maximum permissible current loads for cables and devices must not be exceeded.
– Always compare the current ratings of the device, the cable and the fuse to ensure that they match.
– In the event that these are not the same, use a separate upstream fuse in order to
provide appropriate overcurrent protection.
•Use only connecting cables with safety plugs for electrical connections.
•When laying connecting cables, make sure they are not kinked or pinched.
•Do not lay cables over hot surfaces.
– Hot surfaces are indicated by a corresponding warning symbol.
•Make sure that connecting cables are not subjected to continuous tensile loads.
•The device is not equipped with a built-in fuse unless otherwise specified in the technical data.
•Pull the plug only when disconnecting connecting cables; never pull the cable.
•Hazard-free operation of the device is no longer possible in the case of:
– Visible damage
– Malfunction
– Incorrect storage
– Incorrect transport.
– Switch off the power supply immediately.
– Protect the device against an inadvertent restart.
5.4 Pneumatics
•Depressurize the system.
– Switch off the compressed air supply before working on the circuit.
– Use pressure gauges to check whether the entire circuit is pressure-free.
– Please note that energy may be stored in reservoirs.
Information on this issue is available in the datasheets and operating instructions included
with the components.
•Do not exceed the maximum permissible pressure of 6 bar (600 kPa).
•Do not switch on the compressed air until all the tubing connectors have been joined and secured.
•Do not disconnect tubing while under pressure.
•Do not attempt to seal or plug pneumatic tubing or plug connectors with your hands or fingers.
•Risk of injury when switching on compressed air!
Cylinders can advance and retract automatically.

Work and safety instructions Mixing Learning System

•Risk of accident due to advancing cylinders.
– Always position pneumatic cylinders so that the piston rod’s working space is unobstructed
over the entire stroke range.
– Make sure that the piston rod cannot collide with any rigid components of the setup.
•Risk of accident due to pneumatic tubing slipping off!
– Use shortest possible barbed tubing connectors.
– If pneumatic tubing slips off:
Switch off the compressed air supply immediately.
•Pneumatic circuit setup:
Connect the devices with plastic tubing with an outside diameter of 4 or 6 mm. Push the pneumatic
tubing into the push-in connector as far as it will go.
•Switch off the compressed air supply before dismantling the circuit.
•Dismantling the pneumatic circuit
Press the blue release ring down so that the pneumatic tubing can be pulled out.
•Noise due to escaping compressed air
–Noise caused by escaping compressed air may damage your hearing. Reduce noise by using
pneumatic mufflers, or wear hearing protection if noise cannot be avoided.
–All of the exhaust ports of the components included in the equipment set are equipped with
mufflers. Do not remove these mufflers.
5.5 Process technology
Always fill the tanks when the power is switched off!
Switch off the 24 V DC and 230 V AC power supply!
•Use tap water of drinking water quality (recommended) to ensure longer maintenance-free operation of
the stations (valves, pump, etc.).
•The maximum operating temperature of the containers of +65°C must not be exceeded.
•Only start up the heater when the heating element is completely immersed in the liquid.
•The maximum operating pressure for the liquid in the pipes must not exceed 0.5 bar.
•Do not allow the pump to run dry. The pump must not be used with seawater, contaminated liquids or
viscous media.
•Drain the liquid in the stations/system before making changes in the piping layout.
•The liquid in the station can be drained by opening the drain valves!
•No liquid should be left in the system for a long period of time, as bacteria such as Legionella can form
in it.
