DEFAULT PARAMETERS
DEFAULT OPERATIVE PARAMETERS
The control parameters can be loaded with predetermined default values. These data are the typical values loaded in the instrument prior to shipment from factory. To load the default values proceed as follows:
a)The internal switch should be closed.
b)The SMART function should be disabled.
c)The upper display will show the process variable while the lower display will show the set point value.
d)the device must be in "UNLOCK" and"LOCAL" conditions
e)Held down t pushbutton and press s pushbutton; the display will show:
O F F
d F L t
e) Press s or t pushbutton; the display will show:
O N
d F L t
g) Press FUNC pushbutton; the display will show:
L O A d
This means that the loading procedure has been initiated. After about 3 seconds the loading procedure is terminated and the instrument reverts to NORMAL DISPLAY mode.
The following is a list of the default operative
PARAMETER | DEFAULT VALUE |
SP | = Minimum |
SnrT | = Disabled |
n.Srt | = OFF |
SP2 | = Minimum range value |
nnn | = OFF |
A1, A2 | = Minimum |
| process alarms |
| 0 for deviation or band alarms |
HSA1, HSA2 | = 0.1 % |
Pb | = 4.0 % |
HyS | = 0.5 % |
ti | = 4.00 (4 minutes) |
td | = 1.00 (1 minute) |
IP | = 30.0 for one control output |
| 0.0 for two control outputs |
Cy2 - Cy3 | = 15 seconds |
| If two control outputs are |
| configured and OUT2 (OUT 3) is |
| configured as "dir", the default |
| value will be equal to: |
| 10 seconds when P22 = AIr |
| 4 seconds when P22 = OIL |
| 2 seconds when P22 = H2O |
rC | = 1.00 for P22 = AIr |
| 0.80 for P22 = OIL |
| 0.40 for P22 = H2O |
OLAP | = 0 |
rL | = Initial scale value |
rH | = Full scale value |
Grd 1 | = Infinite (step transfer) |
Grd 2 | = Infinite (step transfer) |
OLH | = 100 % |
tOL | = Infinite |
rnP | = 25.0 % /s. |
