Nastec ANDO VASCO - IN; out Parameters

Parameter Default Description
Autorestart
ON/OFF
OFF By selecting ON, when the mains power is restored after a power failure, the device will return to the
same state it was in before the power failure: this means that if the pump was working, it will start
working again
Change PASSWORD2
Press ENT
By pressing the ENT key it is possible to change the advanced level password (level 2) (default 002).
9.9. IN / OUT parameters
Parameter Default Description
Unit
XXXXX
bar Units of measurement [bar,%, ft, in, cm, m, K, F, C, gpm, l / min, m3 / h, atm, psi].
F.scale sensor
p = XXX.X [bar]
16 Full scale of the sensor.
Min.value sensor
p = XXX.X [bar]
0 Minimum sensor value.
Offset input1
XX.X [%]
20% Zero correction for analog input 1 (4-20 mA).
(20 mA x 20% = 4 mA).
Offset input2
XX.X [%]
20% Zero correction for analog input 2 (4-20 mA).
(20 mA x 20% = 4 mA).
Offset input3
XX.X [%]
20% Zero correction for analog input 3.
4-20 mA : 20 mA x 20% = 4 mA
0-10 V : 10V x 0% = 0 V
Offset input4
XX.X [%]
0% Zero correction for analog input 4.
4-20 mA: 20 mA x 20% = 4 mA
0-10 V : 10V x 0% = 0 V
AN1 AN2 function
XXXXXXXX
Inde-
pendent
Operating logic of analog inputs AN1, AN2:
• Independent. The active sensor is relative to analog input 1, while the sensor connected to analog
input 2 serves as an auxiliary in case of failure of the sensor or of analog input 1.
• Selectable. The active sensor may be selected via digital input 3.
• Difference 1-2. The digital difference in absolute value is performed between the measurements of
analog input 1 and analog input 2.
• Higher value. The maximum value between the measurements of the two sensors is considered.
• Lower value. The minimum value between the measurements of the two sensors is considered.
Digital input1
N.O./N.C.
N.O. If N.O.(Normally Open) is selected, the device will continue to operate the motor if digital input 1 is
open. Conversely, it will stop the motor if digital input 1 is closed.
If N.C. (Normally Closed) is selected, the device will continue to operate the motor if digital input 1 is
closed. Conversely, it will stop the motor if digital input 1 is open.
Digital input2
N.O./N.C.
N.O. If N.O.(Normally Open) is selected, the device will continue to operate the motor if digital input 2 is
open. Conversely, it will stop the motor if digital input 2 is closed.
If N.C. (Normally Closed) is selected, the device will continue to operate the motor if digital input 2 is
closed. Conversely, it will stop the motor if digital input 2 is open.
Digital input 2 is also used to select set value 1 or set value 2 in the control mode Const.value 2set or
to select working frequency 1 or 2 in the control mode Fix speed 2 val..
Digital input3
N.O./N.C.
N.O. If N.O.(Normally Open) is selected, the device will continue to operate the motor if digital input 3 is
open. Conversely, it will stop the motor if digital input 3 is closed.
If N.C. (Normally Closed) is selected, the device will continue to operate the motor if digital input 3 is
closed. Conversely, it will stop the motor if digital input 3 is open.
Digital input 3 is also used to select sensor 1 or sensor 2 when the parameter AN1 AN2 function is
set to Selectable.
Digital input4
N.O./N.C.
N.O. If N.O.(Normally Open) is selected, the device will continue to operate the motor if digital input 4 is
open. Conversely, it will stop the motor if digital input 4 is closed.
If N.C.(Normally Closed) is selected, the device will continue to operate the motor if digital input 4 is
closed. Conversely, it will stop the motor if digital input 4 is open.
Digital input 4 is also used to select the main or auxiliary control mode in case they are different.
Digital input 4 also serves as alarm reset.
