USER MENU
User Menu configuration parameters
we have provided to divided it in families.
LABEL MIN. MAX. U.M. USER MENU PASSWORD
PA -999 9999 ---- User Menu password (2)
Notes
• the symbol (2) indicates that the parameter is available to the
first level only.
PA User Menu password
It is the password who permits to gain access to the second level of the
User Menu.
LABEL MIN. MAX. U.M. MEASURE INPUTS
/A1 -999 999 (3) suction probe calibration (1)
/b1 -999 999 (4) condensing probe calibration (1)
/ 2 0 6 ---- digital filter
/ t 0 1 ---- temperature unit of measure
/5P 0 3 ---- pressure decimal point position
/bE 0 2 ---- kind of condensing probe
/A6 -999 9999 point lower end of scale for 4-20 mA input
(it coincides with the minimum cali-
bration value of the suction trans-
ducer)
/A7 -999 9999 point upper end of scale for 4-20 mA input
(it coincides with the maximum cali-
bration value of the suction trans-
ducer)
/b6 -999 9999 point lower end of scale for 4-20 mA input
(it coincides with the minimum cali-
bration value of the condensing trans-
ducer)
/b7 -999 9999 point upper end of scale for 4-20 mA input
(it coincides with the maximum cali-
bration value of the condensing trans-
ducer)
/U 0 1 ---- kind of analog output (only for de-
vices with analog output in current)
Notes
• the symbol (1) indicates that the parameter is available both to
the first and to the second level
• the symbol (3) indicates that the unit of measure depends from
the parameter /5P and from the parameters /A6 and /A7 (the
parameters /5P, /A6 and /A7 belong to the User Menu; see the
chapter User Menu on the page 32)
• the symbol (4) indicates that the unit of measure depends from
the parameter /bE (the parameter /bE belongs to the User
Menu; see the chapter User Menu on the page 32): if the
condensing probe is a 2 wires 4-20 mA pressure transducer
the unit of measure depends from the parameters /5P, /b6
and /b7 (the parameters /5P, /b6 and /b7 belong to the User
Menu; see the chapter User Menu on the page 32), if the
condensing probe is a PTC probe the unit of measure depends
from the parameter / t (the parameter / t belongs to the User
Menu; see the chapter User Menu on the page 32).
/A1 suction probe calibration
It establishes a threshold to add algebraically to the signal coming from
the suction probe (for instance to correct the signal).
/b1
condensing probe calibration
It is significant exclusively if the parameter /bE has value 1 or 2, it
establishes a threshold to add algebraically to the signal coming from
the condensing probe (for instance to correct the signal).
/ 2
digital filter
It establishes a time constant to apply to the signals coming from the
measure inputs, as indicated:
0
= 0 sec.
1 = 0.4 sec.
2 = 1.2 sec.
3 = 3.0 sec.
4 = 8.0 sec.
5 = 19.8 sec.
6 = 48.0 sec.
/ t temperature unit of measure
It is significant exclusively if the parameter /bE has value 2, it establishes
the unit of measure with which the temperature gets displayed, as
indicated:
0
= the unit of measure is the Fahrenheit degree
1 = the unit of measure is the Celsius degree.
/5P pressure decimal point position
It establishes where to display the decimal point when a pressure gets
displayed, as indicated:
0
= the decimal point gets not displayed
1 = the decimal point gets displayed on the dozens display
2 = the decimal point gets displayed on the dozens hun-
dreds
3 = the decimal point gets displayed on the dozens thou-
sands.
/bE kind of condensing probe
It establishes the kind of condensing probe that the instrument must
recognize, as indicated:
0
= the condensing probe is disabled
1 = 2 wires 4-20 mA pressure transducer
2 = PTC probe.
If the parameter /bE has value 0, a power step loading/unloading
gives the automatic activation/deactivation of a condenser fans.
/A6
lower end of scale for 4-20 mA input (it coincides
with the minimum calibration value of the suction
transducer)
It establishes the lower end of scale for 4-20 mA input and it must
coincide with the minimum calibration value of the suction transducer.
