4���20 mA with setting [OU2] = I or
20���4 mA with setting [OU2] = Ineg�
The measuring range is scalable:
• [ASP] defines at which measured temperature value the analogue signal is
4 mA (OU2 = I) or 20 mA (OU2 = Ineg)�
• [AEP] defines at which measured temperature value the analogue signal is
20 mA (OU2 = I) or 4 mA (OU2 = Ineg)�
Minimum distance between [ASP] and [AEP] = 5 K�
If the measured temperature value is outside the scaled measuring range, the
analogue signal is 20...20.5 mA or 3.8...4 mA (→ Figure 1). When the measured
temperature value continues to increase or decrease, case of diagnostic 5 occurs
