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 SMART function should be disabled.
b) The instrument is in "UNLOCK" condition.
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:
e) Press s or t pushbutton; the display will show:
f) Press FUNC pushbutton; the display will show:
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 parameters
loaded during the above procedure:
PARAMETER DEFAULT VALUE
SP = Initial scale value
SñRT = Disable
ñ.SRt = OFF
SP2 = Initial scale value
SP3 = Initial scale value
SP4 = Initial scale value
nnn = OFF
AL1 = Initial scale value for process alarm
0 for deviation or band alarm
HSA1 = 0.1 %
AL2 = Initial scale value for process alarm
0 for deviation or band alarm
HSA2 = 0.1 %
AL3 = Initial scale value for process alarm
= 0 for deviation or band alarm
HSA3 = 0.1 %
PB = 4.0 %
HyS = 0.5 %
ti = 4.00 (4 minutes)
td = 1.00 (1 minute)
IP = 30 % if one control output is
configured
= 0 if two control outputs are
configured
Cy2 = 15 seconds for relay output
4 seconds for SSR output
When two control output are
programmed and OUT 2 = "dir" the
default value will be:
10 seconds for P25 = AIr
4 seconds for P25 = OIL
2 seconds for P25 = H2O
Cy3 = 15 seconds for relay output
When two control output are
programmed and OUT 3 = "dir" the
default value will be:
10 seconds for P25 = AIr
4 seconds for P25 = OIL
2 seconds for P25 = H2O
rC = 1.00 for P25 = AIr
= 0.80 for P25 = OIL
= 0.40 for P25 = 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
rñP = Infinite
