PROGRAMMING

I. Programming REV mA (Optional):

In factory default, 

t

he

transmitter operates with 4 mA at the maximum range (MaxR), and

20 mA at the dead band (MinR). Using the menu item REV mA, you

can change the unit to reverse this to 20 mA at the furthest distance

(MaxR) and 4 mA at the closest distance (MinR). 

NOTE: You must set HEIGHT and FULL R prior to reversing

the 4 and 20 mA.  Regardless of which mode you are in (Norm

or Rev), changes to the HEIGHT or FULL R are always with

respect to the original settings programmed.

NOTE: Any changes to the HEIGHT will effect the FULL R

value.  The FULL R will stay at the same physical level in the

tank.  An increase to the HEIGHT value will result in an equal

increase to the FULL R value.  A decrease to the HEIGHT value

will result in an equal decrease to the FULL R value.

PROGRAMMING

G. Programming HEIGHT:

To change HEIGHT 4 mA value.

1. Press the SELECT/FAST button and hold it for 5 seconds until

PROG appears.

2. When TANK appears, press the SELECT/FAST button. The dis-

play will rotate between HEIGHT, FILL H and REV mA.

3. When HEIGHT appears, press the SELECT/FAST button. The

display will show a decimal reading in the selected UNITS. 

4. Press the UP/DOWN buttons to increase or decrease this value to the

distance from the transducer face to the bottom of the tank.  NOTE:

Simultaneously holding down the SELECT/FAST button while press-

ing the UP or DOWN button will increase the speed of the display. 

5. When you have reached the desired value, press SELECT/FAST

to SAVE.

You have successfully programmed the HEIGHT or 4 mA value.

H. Programming FILL H:

To change FILL H 20 mA value.

1. Press the SELECT/FAST button and hold it for 5 seconds until

PROG appears.

2. When TANK appears, press the SELECT/FAST button. The dis-

play will rotate between HEIGHT, FILL H and REV mA.

3. When FULL H appears, press the SELECT/FAST button. The dis-

play will show a decimal reading in the selected UNITS. 

4. Press the UP/DOWN buttons to increase or decrease this value to

the distance from the bottom of the vessel to the full point (typi-

cally the straight wall height). 

5. When you have reached the desired value, press SELECT/FAST

to SAVE it.

You have successfully programmed the FILL H or 20mA value.

NOTE: You can increase the speed at which the display changes

by pressing the SELECT/FAST button while simultaneously hold-

ing down the UP or DOWN button.
