To return to the operator level, PROG must be pressed for three
seconds. If no keys are pressed for 2 minutes, the
MTL661/2/3/5 will leave the SETUP mode automatically.

3 .1 .3 Details of SETUP functions
1 - DISPLAY
11 UNIT
This determines the measurement unit that will be displayed. A
choice can be made from the range of units shown in Section 3.2.2.
Alteration of the measurement unit will have consequences for
other SETUP-level values.
Please note that the Span has to be adapted as well; the calculation
is not done automatically.
12 TIME
For flowrate calculations, a time unit can be set. The flowrate can
be calculated per second (/SEC or /S); minute (/MIN or /M); hour (/
HR or /H) or day (/DAY or /D).
Select “———” if no time unit is desired.
13 DECIMALS
This setting determines the number of digits following the decimal
point. The following can be selected:
000000 - 11111.1 - 2222.22 - 333.333
14 OFFSET
The offset is the minimum
displayed
value of the range of
measurement. This needs to be programmed into the display.
Example: Setting a temperature range
For a temperature range of 20°C to 120°C, the offset at the minimum
signal of 4mA is 20°C.
Therefore make offset
20°C
.
The minus for a negative value can be selected by pressing
the
and
button simultaneously.
15 SPAN
The span is the difference between the maximum and minimum
displayed
values for the range of 4 to 20mA inputs.
Example: Setting a temperature range
For a temperature range of 20°C to 120°C, the span is the difference
between the top and the bottom values of the range, i.e. 100°C.
Therefore set span to
100°C
.
Example: Programming the span for a flowrate
Assume that a sensor generates 20mA at a flowrate of 2,481.3 litres/
minute; then select the unit as “Litres”, the time unit as “minute”
and the number of decimals as “1”.
Set the span as 2481.3
Enter for SETUP - 15: “2481.3”.
16 DIRECTION
If the display is required to increase in value as the input current
increases, select the scale direction “normal”. Alternatively, select
“reverse” if the display is required to decrease as the input current
rises.
17 CURRENT
Select “enable” if you want the actual current value to be displayed
for the operator.
18 PERCENTAGE
Select “enable” if you want to the 0% value and 100% value to be
displayed for the operator.
19 PIEGRAPH
The piegraph (displayed at operator level) displays the input signal
as a percentage. The minimum signal (setup 23) corresponds to 0%
and the maximum signal (setup 24) to 100%.
With this function, the piegraph can be enabled / disabled.
