APPENDIX A

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 parame-ters loaded during the above procedure:

PARAMETER

DEFAULT VALUE

SP

= Minimum range-value

SnrT

= Disabled

n.Srt

= OFF

SP2

= Minimum range value

nnn

= OFF

A1, A2

= Minimum range-value for

 

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.
