Ceraphant PTP31B, PTP33B Commissioning
Endress+Hauser 35
Prerequisite • This function is only available if the window function has been defined for the switch
output.
• The upper value of the pressure window "FH1/FH2" must be greater than the lower value
of the pressure window "FL1/FL2"!
A diagnostic message is displayed if the upper value entered for the pressure window
"FH1/FH2" is smaller than the lower value of the pressure window "FL1/FL2". While it is
possible to make this entry, it does not take effect in the device. The entry must be
corrected!
Selection No selection. The user is free to edit the values.
Factory setting Factory setting if no customer-specific setting is ordered:
Switch point FH1: 45 %; switchback point FL1: 44.5 %
Switch point FH2: 55 %; switchback point FH2: 54.5 %
8.8 Current output
STL value for 4 mA (LRV)
Navigation STL
Description Assignment of the pressure value which should correspond to the 4 mA value.
It is possible to invert the current output. To do so, assign the pressure upper range value
to the lower measuring current.
Prerequisite Electronic version with current output
Note Enter the value for 4 mA in the selected pressure unit anywhere within the measuring
range. The value can be entered in increments of 0.1 (increment depends on the
measuring range).
Selection No selection. The user is free to edit the values.
Factory setting 0.0 or as per order specifications
STU value for 20 mA (URV)
Navigation STU
Description Assignment of the pressure value which should correspond to the 20 mA value.
It is possible to invert the current output. To do so, assign the pressure lower range value
to the upper measuring current.
Prerequisite Electronic version with current output
Note Enter the value for 20 mA in the selected pressure unit anywhere within the measuring
range. The value can be entered in increments of 0.1 (increment depends on the
measuring range).
