Notes
• 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).
AC0
hysteresis (differential)
It is significant exclusively if the parameter /bE has value 1 or 2 and if
the parameter AC4 has value 1 or 2, it establishes the hysteresis (differ-
ential) relative to the setpoint established with the parameter AC1.
For further informations about the parameter AC0 meaning see the
paragraph Upper condensing quantity alarm on the page 15.
AC1
alarm setpoint
It is significant exclusively if the parameter /bE has value 1 or 2 and if
the parameter AC4 has value 1 or 2, it establishes the condensing
quantity value above which the upper condensing quantity alarm gets
activated according with the modality established with the parameter
AC4 and it is referred to the condensing probe.
For further informations about the parameter AC1 meaning see the
paragraph Upper condensing quantity alarm on the page 15.
AC4
kind of alarm
It is significant exclusively if the parameter /bE has value 1 or 2, it
establishes the kind of upper condensing quantity alarm that the instru-
ment must manage, as indicated:
0
=
the upper condensing quantity alarm never gets acti-
vated
1
=
absolute upper condensing quantity alarm
2
=
upper condensing quantity alarm relative to the
setpoint established with the parameter F 1.
For further informations about the parameter AC4 meaning see the
paragraph Upper condensing quantity alarm on the page 15.
AC7
disabling time to the upper condensing quantity
alarm activation
It is significant exclusively if the parameter /bE has value 1 or 2 and if
the parameter AC4 has value 1 or 2, it establishes the time that disables
an upper condensing quantity alarm activation from the moment in
which the upper condensing quantity alarm happens.
For further informations about the parameter AC7 meaning see the
paragraph Upper condensing quantity alarm on the page 15.
ACn
number of upper condensing quantity alarms
enough to give the instrument locking
USER MENU
User Menu configuration parameters
Notes
• 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).
Ab0
hysteresis (differential)
It is significant exclusively if the parameter Ab4 has value 1 or 2, it
establishes the hysteresis (differential) relative to the setpoint estab-
lished with the parameter Ab1.
For further informations about the parameter Ab0 meaning see the
paragraph Upper pressure alarm on the page 15.
Ab1
alarm setpoint
It is significant exclusively if the parameter Ab4 has value 1 or 2, it
establishes the pressure above which the upper pressure alarm gets
activated according with the modality established with the parameter
Ab4 and it is referred to the suction probe.
For further informations about the parameter Ab1 meaning see the
paragraph Upper pressure alarm on the page 15.
Ab4
kind of alarm
It establishes the kind of upper pressure alarm that the instrument must
manage, as indicated:
0
=
the upper pressure alarm never gets activated
1
=
absolute upper pressure alarm
2
=
upper pressure alarm relative to the working setpoint.
For further informations about the parameter Ab4 meaning see the
paragraph Upper pressure alarm on the page 15.
Ab7
disabling time to the upper pressure alarm activa-
tion
It is significant exclusively if the parameter Ab4 has value 1 or 2, it
establishes the time that disables an upper pressure alarm activation
from the moment in which the upper pressure alarm happens.
For further informations about the parameter Ab7 meaning see the
paragraph Upper pressure alarm on the page 15.
Abn
number of upper pressure alarms enough to give
the instrument locking
It establishes the number of upper pressure alarms enough to give the
instrument locking.
If the parameter Abn has value 0 the instrument locking never hap-
pens.
For further informations about the parameter Abn meaning see the
paragraph Upper pressure alarm on the page 15.
