You inform the device of the sensor installation location using the
Sensor location
parameter.

are available for selection. The selection is not evaluated in the device,
it only serves an informational purpose in the medium in which the temperature measurement takes place.
Parameter:
Sensor number
•
Default setting
(_:11101:44) sensor number
=
no function block selected
With the
sensor number
parameter, you assign a specific sensor whose temperature is to be monitored to
the Location function block. You perform the assignment in DIGSI using a list box that contains all connected
RTD units and their sensors.
Parameter:
Threshold stage 1
•
Default setting
(_:11101:40) Threshold stage 1
=
100°C
With the
Threshold stage 1
parameter you establish the temperature value whose exceedance causes a
pickup of the 1st tripping stage.
Parameter:
Operate delay of stage 1
•
Default setting
(_:11101:41) Operate delay of stage 1
=
5 s
With the
Operate delay of stage 1
parameter you establish the time the operate indication of the 1st
tripping stage should be delayed after the pickup. This time delay depends on the specific application. If you
set the time delay to ∞ the operate indication is blocked.
Parameter:
Threshold stage 2
•
Default setting
(_:11101:42) Threshold stage 2
=
120°C
With the
Threshold stage 2
parameter you establish the temperature value whose exceedance causes a
pickup of the 2nd tripping stage.
Parameter:
Operate delay of stage 2
•
Default setting
(_:11101:43) Operate delay of stage 2
=
0 s
With the
Operate delay of stage 2
parameter you establish the time the operate indication of the 2nd
tripping stage should be delayed after the pickup. This time delay depends on the specific application. If you
set the time delay to ∞ the operate indication is blocked.
Temperature Unit
Temperature Unit To change the display and evaluation of measured temperature values from °C to °F, adapt
the DIGSI user default settings accordingly (see
5.6.7.5 Temperature Sensor ).
