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 instrument must be in "UNLOCK" condition
b) The SMART function is disabled.
c) The upper display will show the process
variable while the lower display will show the
set point value.
d) Held down t pushbutton and press s
pushbutton; the display will show:
O F F O F F
O F F O F F O F F
dFLt dFLt dFLt dFLt dFLt
e) Press s or t pushbutton; the display will show:
O N O N O N O N O N
dFLt dFLt dFLt
dFLt dFLt
g) Press FUNC pushbutton; the display will show:
LOAd LOAd LOAd
LOAd LOAd
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
parame-ters loaded during the above procedure:
LFS-servo-Z-01.p65 1
PARAMETER DEFAULT VALUE
SP = minimum range-value
Snrt = Disable
m. r St = OFF
SP2 = minimum range value
= OFF
nnn
A1 A2 A3 = minimum range value for
process alarms
0 for deviation or band alarms
HSA1 HSA2 HSA3 = 1
= 1.5 %
PB
hyS = 0.5 %
ti = 2.00 (2 minutes)
td = 0.10 (10 seconds)
IP = 50 % for servomotor control drive
30 % for one time proportional
control output
0 % for two control outputs.
Sm. t t = 0.25 (seconds)
Sm. d b = 5 (%)
= 0 (%)
Sm. LL
Sm. H L = 100 (%)
Cy1 = 15 (seconds)
When two control outputs are
configured and the OUT1 has a
"dir" action, the CY1 default
value will be equal to:
10 seconds for P25 = AIr
4 seconds for P25 = OIL
2 seconds for P25 = H2O
Cy3 = 15 (seconds)
When two control outputs are
configured and the OUT3 has a
"dir" action, the CY3 default
value will be equal to:
10 seconds for P25 = AIr
4 seconds for P25 = OIL
2 seconds for P25 = H2O
