To prevent switch-on and switch-off if values are around the switch point "SP1" or the
switchback point "RP1", 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.
• SP1 = 2 bar (29 psi)
• RP1 = 1 bar (14.5 psi)
• dS1 = 5 seconds
• dR1 = 2 seconds
dS1/: ≥2 bar (29 psi) must be present for at least 5 seconds for SP1 to become active.
dR1/: ≥1 bar (14.5 psi) must be present for at least 2 seconds for RP1 to become active.
