SAFETY FUNCTIONS AND SAFETY EQUIPMENT
3.7 Pneumatic safety valve (optional)
If compressed air is used in the machine, the machine will feature a compressed
air maintenance unit with pressure regulating valve, including a pressure gauge to
display the system pressure (for setting the operating pressure), an electric switch-
on and shut-off valve, and a manual switch-on and shut-off valve to separate the
machine from the compressed air supply (customer's air network).
A system pressure sensor to monitor the customer's network is also installed.
3.8 Warning signals/indicators
Various indications, alerts, and fault/error messages are displayed on the screen.
They are usually self-explanatory.
The machine status is signaled by an LED multi-indicator lamp.
3.9 Keys and password protection
Access to the various operating modes and settings is protected using keys and
passwords.
Do not allow keys or passwords to come into the hands of unauthorized persons.
Setup mode is safeguarded by a key.
The key must be pulled out again once setup mode is finished.
Machine programs and other safety-critical settings can only be accessed after
entering the corresponding passwords.
The passwords are linked to a number of protection levels.
The protection levels available are determined by the customer's requirements and
the configuration used by the manufacturer.
3.10 Confirmation mode
In setup mode with the work area door open, hazardous movements can only be
started when both the confirm key and the action key are pressed.
If one of the keys is released, the movement is stopped.
