Description of device parameters Ceraphant PTP31B, PTP33B
50 Endress+Hauser
Prerequisite • These functions are only available if the hysteresis function has been defined for the
switch output.
• The configured value for the switch point "SP1/SP2" must be greater than the switchback
point "RP1/RP2"!
A diagnostic message is displayed if a switch point "SP1/SP2" is entered that is ≤ the
switchback point "RP1/RP2". While it is possible to make this entry, it does not take
effect in the device. The entry must be corrected!
Note To prevent constant switch-on and switch-off if values are around the switch point "SP1/
SP2" and switchback point "RP1/RP2", a delay can be set for the relevant points. See the
parameter description for "dS1/dS2" and "dR1/dR2" for this purpose.
Selection No selection. The user is free to edit the values.
Factory setting Factory setting (if no customer-specific setting is ordered):
Switch point SP1: 45 %; switchback point RP1: 44.5 %
Switch point SP2: 55 %; switchback point RP2: 54.5 %
