GENERAL INFORMATION

LCD-H20 is a digital indicator for installation directly in a
4-20 mA loop without need for external power.
It is designed for in-head mounting in a sensor connection head

with window.
The indicator is equipped with 12 mm LCD digits.
The scale is easily programmable, without reference signal, by 3

pushbuttons for any values between -1999 and 9999.
As an option, LCD-H20 can be delivered mounted in a

connection head.

CONFIGURATION

Programming: The programming is executed through 3 keys

mounted on the bottom of the display. The central key is the
Enter (F) key. The lateral keys act as the up

S and down T

digit; they also act as selection of the parameters.

Ke y Function
F Access to the programming; move to the following parameter menu;

saving of data and close of the programming

T Decreasing digit; selection/set-up of a parameter
S Increasing digit; selection/set-up of a parameter
S + T “Escape”

Operation: Press the key F for more than 3 seconds to get access to the
programming procedure. The display will visualize the “dP” function, which is the
first programming section: Decimal Point. By pressing the S
T(decrease) keys it’s possible to scroll all the other programming windows. At
the end of the programming phase the modified parameters are stored auto­matically and retained also during the switch off of the instrument.

Programming procedure:
Set-up of the decimal point (dP)

Press the S or T

keys to select the decimal point position (from zero to 3

decimals). Press F to confirm. Default = 1 decimal

Set-up of the engineering value related to the zero point (ZErO)

Press the S or T keys to select the engineering value zero (-1999 to

9999). Press F to confirm. Default = 0.0

Set-up of the engineering value related to the span range (SPAn)

Press the S or T keys to select the engineering range value (-1999
+9999). Press F to confirm. Default = 100.0

CALIBRATION

Set-up of the limit on the input current (Li) This parameter allows to

select the over-load limit of the visualization.
If Li = 0, when the current overcomes the 20 mA value, the display will indi­cate the OverLoad message OL (-OL when the current is lower that 4 mA).
If Li = 1, the visualization will be extended of a 10% over the 4...20 mA
range, before indicating the overload. In both cases, overcoming the
display maximum readings (-1999 +9999), the overload message will be
indicated. Default = 1

Set-up of the filter (FiLt) When the 4...20 mA is disturbed it is possible
to select an higher value of FiLt in order to get a more stable and clear
visualization on the display.
Press the key S to increase the filter value on the input and the key T to
decrease the filter value.
It’s possible to set-up different values from 1 to 8; when FiLt = 1 no filter
is applied on the input and the digital reading occurs every 250 ms.
In this case the updating period of the display will be 250 ms multiplied by
the FiLt value. Example: if FiLt = 5 the updating period of the display will
be 1.25 s. Default = 2

Set-up of resolution (riS) This function allows to set-up the resolution
of the display; when riS = 1 the display will indicate all the available digit in
the scale, within the programmed range.
When riS = 2 the steps between two consecutive readings will be doubled:
with riS = 2 it will not be possible to indicate odd numbers.
Selectable values for riS are: 1, 2, 5 and 10.
It is suggested to increase the resolution only if the set range is very large
(example 10000 points) and/or if the 4...20 mA signal is quite unstable: on
the contrary the maximum resolution is normally used. Default = 1

Summary

Ke y Function Disply

programmimg window and to save the modifications.

S Increasing digit 0 to 9
T Decreasing digit 9 to 0
S + T Exit the programmimg without saving

By pressing contemporary the S + T keys for more than 3 s, it is possible
to access to the calibrating function where it is possible to calibrate the
zero and the full scale of the A/D converter of the digital indicator.

Entering this procedure and modifying the parameters will change

!

the factory calibration data. This function must be executed by
specialised personnel only by using adequate instrumentation. A wrong
calibration will affect the right functionality of the instrument itself.

Step 1: Zero-point calibration

Inside the calibration window, select the ZERO point calibration (C4) by
pressing S

or T keys. Apply a 4 mA current to the instrument, wait for the

stabilization of the signal and of the indication and press the key F until the
indication CAL will appear on the display. After few seconds, the new
engineering ZERO value will be indicated.
Exit the Zero-point calibration by pressing S

+ T keys together and pro-

ceed with the Full Scale calibration.

Step 2: Full scale calibration

Inside the calibration window, select the Full Scale calibration (C20) by
pressing S

or T keys. Apply a 20 mA current to the instrument and pro-

ceed as for the Zero-point calibration.
