Abstract
Method for start-up of a field device, wherein for start-up of the field device an energy storage unit (R) for storing electrical energy is charged by means of a power supply (PS), preferably a power-limited power supply (PS), and wherein the electrical energy stored in the energy storage unit (R) is used to supply the field device at least at times with electrical energy, at least during start-up of the field device.
Claims14
A method for start-up of a field device, comprising:
- charging an energy storage unit for storing electrical energy, the energy storage unit being charged by means of a power-limited power supply;
- and
- using the electrical energy stored in the energy storage unit to supply the field device at least at times with electrical energy, at least during start-up of the field device, wherein:
- the electrical energy transferred during start-up from the power supply to the field device is limited, by means of an electrical current limiting unit, which is especially a part of the start-up unit.
1 more element
An apparatus, comprising:
- a chargeable energy storage unit for start-up of a field device, wherein:
- said energy storage unit serves to supply the field device at least during start-up of the field device at least at times with electrical energy;
- and
- the electrical energy transferredduring start-up from the power supply to the field device is limited, by means of an electrical current limiting unit, which is especially a part of the start-up unit.
1 more element
A field device for use in an apparatus, comprising:
- a chargeable energy storage unit for start-up of a field device, wherein:
- said energy storage unit serves to supply the field device at least during start-up of the field device at least at times with electrical energy;
- wherein:
- the electrical energy transferred during start-up from the power supply to the field device is limited, by means of an electrical current limiting unit, which is especially a part of the start-up unit.
