Fault annunciators and fault annunciator systems

DOLD_fault annunciators.png

By lamps, buzzers or also in form of clear text DOLD fault annunciators inform on faults and conditions in electrical installations in industrial facilities and buildings. They also inform on work operations to be done. DOLD fault annunciators considerably reduce the time for fault finding in particular in complex machines and plants. Thus they help to minimize downtimes of production plants and save cost.

Apart from simple electrical group fault, new-value and first-up annunciators, electronic clear text fault annunciating systems are available for complex applications.
Especially when programmable logic controllers (PLC) or management systems are used it is indispensable to install fault alarm acquisition independent of the process level to keep control when the plant control fails and to avoid damages.

Applications:
- Monitoring of machinery and plants of any kind
- Building monitoring
