!
When carrying out these tasks, the provisions and instructions of the accident
prevention regulations VBG 4.0 must be observed. Point 8 is of particular
importance: "Permissible deviations while working on active parts". Appropriate
electrical tools are to be used.
To calibrate the device, the transducer needs to be opened and the subassembly
units removed.
After disconnecting the external wiring, open the lid of the transducer and
remove the subassembly units. The circuit comprises the following units:
– measuring module
– connection module
– power supply unit
The trimming potentiometers are on the measuring module.
Special care is required during work on the open modules, since hazardous
voltages could be present on the back of the measuring module and power
supply unit.
Therefore, the back of the modules should be appropriately covered.
