Parameters in the pressure switch digital display

Menu setting for the switching output
Password is preset. You can change to the programming mode
PAS
only after entering the correct digits.
The programming mode for the switching output:
S1
S1 = switching output 1
S2
S2 = switching output 2
(This menu does not function when S2 is set as the error output)
Switching point (SP): the upper pressure limit, at which the
SP1
switching output changes its state.
SP2
SP1 = switching output 1; input pressure value (e.g. 400 bar)
SP2 = switching output 2; input pressure value (e.g. 430 bar)
Reverse switching point (rSP): the lower pressure limit, at
rSP1
which the switching output changes its state.
rSP2
rSP1 = Reverse switching point (rSP1) of switch output 1;
input as pressure value (e.g. 390 bar)
rSP2 = Reverse switching point (rSP2) of switch output 2;
input as pressure value (e.g. 420 bar)
The reverse switching point is always lower. than the respec-
tive switching point
If the reverse switching point is set higher than the switching
point, the reverse switching point will automatically be reset to
a value that is 0.5% of the nominal device pressure lower than
the switching point. The warning message Att (Attention) ap-
pears, which can then be cleared by pressing Enter
