VOEST‑ALPINE Monitoring and Reporting System. All relevant machine and opera-
tional data can be measured and recorded on board of the roadheader (Fig. 6-19). This
data is then sent, either through the 1,000 V supply cable or a data cable, to above ground
where the current operational conditions are displayed on a screen. Reporting software
is provided to generate shift reports over longer periods of time, and can also include the
detection of trends. The advance rate and machine condition are monitored and recorded.
This offers considerable cost-saving potential in maintenance and site organisation.

Safety and overload protection functions. Sensors are used to detect dangerous operat-
ing conditions and activate appropriate countermeasures through the control system, in
an extreme case the activation of the emergency system (Fig. 6-20). Appropriate software
controls the machine functions so that overloading of the machine structure and drive
are limited. This means that the machine operator can use the product to the limits of
its performance. The protection objectives of EN 954 and EN 61508 are complied with
regarding safety.
Tele‑operation and underground communication. Remote control of roadheaders is
also possible through video systems (Fig. 6-21), but is only used in particularly restricted
space or for safety reasons. This option is mainly used in mining.
Electronic operating manuals and maintenance aids. The AMOR control system is
equipped with a self-test, and the maintenance aids are continuously updated. The mainte-
nance aids shorten the service times. If required by the customer, the electronic handbook
can also be installed and an electronic parts list is also available.
