Work instructions and safety precautions
General
Trainees should only work with the circuits under the supervision of a trainer.
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 the specifications included in the data sheets for the individual components and in particular
all safety instructions!
Faults which may impair safety must not be generated in the training environment and must be
eliminated immediately.
Wear personal safety gear (safety glasses, safety shoes) when working on circuits.
Mechanical setup
Do not touch the setup unless all moving parts have come to a complete standstill.
Mount all the components securely onto the profile plate.
Limit switches must not be actuated at the front.
Risk of injury during troubleshooting.
Use a tool such as a screwdriver, for example, to actuate the limit switches.
Set the components up so that activation of switches and disconnectors is not rendered difficult.
Adhere to the instructions regarding positioning of the components.
Electrical setup
Use low voltage only (max. 24 V DC).
Electrical connections must only be established and interrupted in the absence of voltage!
Only use connecting cables with safety plugs for electrical connections.
Only pull the plug when disconnecting connecting cables – never pull the cable.
Pneumatic setup
Do not exceed the maximum permissible pressure of 600 kPa (6 bar).
Do not switch on the compressed air until all of the tubing connections have been completed and
secured.
Do not disconnect tubing while under pressure.
Risk of injury when switching on compressed air.
Cylinders can advance and retract automatically.
Risk of accidents from rebounding tubing.
–
Use the shortest possible tubing connections.
–
If tubing jumps loose:
switch off the compressed air supply immediately.
Pneumatic circuit assembly
connect the devices using plastic tubing with an outside diameter of 4 mm or 6 mm. Push the tubing as
far as possible into the push-in connector.
Switch off the compressed air supply before disassembling the circuit.
Pneumatic circuit disassembly
press down on the blue release ring to pull out the tubing.
