<strong>Turbine</strong><br />
Operation<br />
<strong>The</strong> turbo generator can be operated<br />
either via a central control system or locally,<br />
directly via the operator interface<br />
on the control panel. In automatic mode<br />
only the turbine start/stop commands<br />
and specification of the setpoint values<br />
are required. All operating modes and<br />
fault messages are displayed locally and<br />
supplied to the control system via a bus<br />
system. In manual mode, local control<br />
of the auxiliary modules and components<br />
is possible.<br />

Safety<br />
All turbine units are provided with extensive<br />
safety equipment that safely shuts<br />
down the steam turbine and generator<br />
when critical conditions are reached.<br />
<strong>The</strong> classification of safety criteria is in<br />
accordance with IEC 61508. Measurement<br />
systems, trip and alarm criteria are<br />
specified in such a way that an optimal<br />
balance between machinery protection<br />
and availability is achieved. If desired,<br />
the design also enables unattended<br />
24-hr operation.<br />

Remote access<br />
A datalogger with ISDN interface enables<br />
remote support for your operating<br />
personnel: Important operating data is<br />
saved to a datalogger and can be analysed<br />
by our Service Team, while our<br />
service engineers have direct access to<br />
the control system and control panel.<br />
This enables us to provide you with<br />
quick and cost-effective support.<br />
