Proline Promass 83 PROFIBUS DP/PA Technical data
Endress+Hauser 149
Recommended full scale values
See → Page 159 ff. (“Limiting flow”)
Operable flow range Greater than 1000 : 1. Flows above the preset full scale value do not overload the amplifier, i.e.
totalizer values are registered correctly.
Input signal Status input (auxiliary input):
U = 3...30 V DC, R

Switch level: ±3...±30 VDC, independent of polarity
Configurable for: totalizer reset, positive zero return, error message reset, start zero point
adjustment, batching start/stop (optional), batching totalizer return (optional)
