2. Safety
Application (see page12):
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, MFC5150
