Ceraphant PTC31B, PTP31B, PTP33B IO-Link Description of device parameters
Hauser 69
Note The switching delay time/switchback delay time function is implemented using the dS2
and dR2 parameters. Since the parameter settings depend on one another, the parameters
are described all together.
• dS2 = switching delay time, output 2
• dR2 = switchback delay time, output 2
Navigation Display: EF → Switching delay.../Switchback delay...
IO-Link: Parameter → Application → Switch output (OU2) → Switching delay.../Switchback
delay...
Description To prevent switch-on and switch-off if values are around the switch point "SP2" or the
switchback point "RP2", a delay in a range of 0 – 50 seconds, to two decimal places, can be
set for the individual points.
If the measured value leaves the switching range during the delay time, the delay time
starts again from scratch.
Example • SP2 = 2 bar (29 psi)
• RP2 = 1 bar (14.5 psi)
• dS2 = 5 seconds
• dR2 = 2 seconds
dS2/: ≥2 bar (29 psi) must be present for at least 5 seconds for SP2 to become active.
dR2/: ≥1 bar (14.5 psi) must be present for at least 2 seconds for RP2 to become active.
