6.3 Operating instructions
Various faults may be indicated when the plant is shut down (see 6.3.2 Shutting down the
plant). These faults must be reset when the plant is started up again.
Through film condensation at the sensors, instantaneous steam leakages will be
announced lately. First the body temperature must be conditioned to the steam temperature
(ca. 10 -15 min.).
The same problem appears at high condensate sub-cooling.
6.3.1 Restart after a power failure
The bus system restarts automatically after a power failure.
The PLC program also starts automatically.
All faults that were stored before the power failure are lost!
