13 WIKA safety manual temperature transmitter T32.xS
11583631.03 08/2014 GB/D/F/E
Application (see page 12):
■ Example 1
Sensor type Pt100, configured measuring range = -50 … +100 °C, so configured
measuring span = 150 K.
This is not smaller than 84 K. Thus the total safety accuracy is 2 % FS,
so 2 % * 150 K = 3 K, or 2 % * 16 mA = 320 μA in terms of the current output
■ Example 2
Sensor type Pt100, configured measuring range = 0 … 50 °C, so configured
measuring span = 50 K
This is smaller than 84 K, thus the total safety accuracy is 2 K,
thus 2 K / 50 K = 4 %, and 4 % * 16 mA = 640 μA in terms of the current output
2.7 Configuration changes
WARNING!
During the configuration change, the safety function is not active! Safe
operation is only admissible with activated write protection (password).
Carry out configuration changes within the permissible specifications in accordance
with chapter 2.1 “Intended use in safety applications”.
With the supplied configuration tools, such items as the write protection for model
T32.xS can be set:
■ Configuration software WIKA_T32
■ AMS
■ SIMATIC PDM
■ DTM in conjunction with operating software to the FDT/DTM Standard, e.g.
PACTware, FieldMate
■ HART ® hand-held terminal FC475, FC375, MFC4150
WARNING!
The safety function must be checked by testing following any configuration
procedure.
