HI 800 101 HIMatrix Engineering Manual
8.6 Repair of Controllers and Modules
The operator may not repair controllers and modules in HIMatrix systems. Defective devices
must be returned to HIMA for repair after being tested by the operator with a brief description
of the fault.
Equipment that has a safety certificate is safety-relevant. The validity of the certificate will
expire if unauthorized repairs are made on safety-related controllers and modules of the
HIMatrix system.
We are not responsible for repairs made without our authorization and this will cancel all
warranties.
8.7 Supply of Internal Documentation
Internal documentation such as internal circuit diagrams, component mounting diagrams and
parts lists of HIMatrix controllers are not part of the general system documentation. For this
reason they are not provided.
