0=0-1V; 1=0-10V; 2=2-10V; 3=0-20mA;
A6 0 to 4 0
Type of outlet sensor;
accessible only in
humidity control with
outlet limiting (A0=3)
4=4-20mA
A7 0 to A8 0 %RH Hi-limit sensor minimum
A8 A7 to 100 100 %RH Hi-
limit sensor maximum
A9 -10.0 to 10.0 0 %RH Hi-limit sensor offset
Accessible only in humidity control with outlet
limiting, (A0=3)
(1): when accessing parameter A0, parameters P2, P3, P7 and St are automatically reset to the corresponding
default value.
(2): see WARNING to the side of Fig. 7.1.
Parameters for configuring the operation of accessory devices:
Code Range Default Unit Description
Special functions
To enable more than one, sum the 0= no function
corresponding values and assign 1= dehumidifier management active
them to b1; e.g.: b1=1+2+8=11 2= drain under power
dehumidifier management active +
4= disable draining on set point
reduction
drain under power + disable draining
8= disable draining for inactivity
for inactivity of at least 7 consecutive
16= disable cylinder being depleted
days (the other functions are
deactivated)
and cylinder depleted warnings
32= reverse the operation of the
alarm relay
b1 0 to 127 0
64= enable periodic draining
b2 0 to 120 0 s Shut-down delay time
b3 -10.0 to 10.0 0 % Current measurement calibration
0 to 199
b4
0k2, ….2k0
0
µS/cm

, otherwise the unit uses the
value as the conductivity to control drain cycles.
0 to 199
b5
0k2, ….2k0
1k5
µS/cm
Conductivity pre-alarm set point
0 to 199
b6

2k0
µS/cm
Conductivity alarm set point
b7 0 to 100 50 % Foam detection set point (0=no foam detect, 1=max sens., 100=min sens.)
b8 50 to 200 100 %
Internal conductivity reached by the cylinder in stable conditions against
rated value
b9 50 to 200 100 % Adjust the duration of the drain for dilution
Cylinder maintenance limit time (in hours)
0*= disable life alarm “Cy” and maintenance alarm “Mn” bb 0* to 4000 1500 h
100 hour step if bb>199 hours, hour step if bb<199 hours
bE 1 to 120 24 h
Time limit between two periodic
drain cycles
Accessible only if periodic draining is
enabled (64 in "b1")
bF 1 to 199 3 days
Days to wait to drain due to inactivity
Not accessible if draining due to
inactivity is disabled, (8 in "b1")
