Safety installations

To protect personnel, the mMS 4.0 training system must be equipped with
the following safety installations:
 EMERGENCY STOP buttons one for each station to complete
the EMERGENCY STOP circuit
 Pneumatic and/or hydraulic pressure limitation
 Mechanical safeguards
The above devices are described in greater detail as follows.
The front of the mMS 4.0 training system has an EMERGENCY STOP button
placed within easy reach.
The EMERGENCY STOP button must be pressed to prevent danger to personnel
or the mMS 4.0 training system.
A component with the EMERGENCY STOP button must be connected
to the mMS 4.0.
If a component with the EMERGENCY STOP button is not connected to the mMS
4.0, the EMERGENCY OFF button is not closed and thus will not be able
to operate.
Pressing the EMERGENCY STOP button puts the system out of operation,
i.e. the control and the drive is switched off; the mMS 4.0 training system is
stopped. The power supply unit, the PLC and the drive continue to be powered
by electricity.
The training system may only be operated at a maximum pneumatic operating
pressure of 5-6 bars. The pressure setting is made at the factory. The
compressed air is switched off when an EMERGENCY STOP is actuated.
The maximum hydraulic operating pressure for the training system is
50 bar. The pressure setting is made at the factory. The hydraulic
power unit is switched off when an EMERGENCY STOP is actuated.
To monitor circuitry in training mode, appropriate pressure gauges/pressure
limiting valves may need to be integrated in the exercise circuitry. The instructor
is responsible for doing so.
The following mechanical safeguards are available:
 Contact protection for the racks, pinning unit
 Contact protection on the conveyor belt
 Contact protection on the press
 Electrical control box for 115-230 V AC components
 Casing of station 3
Additional control technology safeguards are affixed:
Light barriers on the conveyor belts
Risk of injury!
Do not remove any light barriers (e.g. from the conveyor belts)

Under no circumstances remove safety instructions or signage - make sure
