Tot.MU=
is the totalizer for the selected Unit of Measure.
There are three fields to set.
1. Unit of Measure
2. Type of unit (see table on page 20)
3. Decimal position
Press
to access these fields. Press
to move
the cursor to the blank space between the unit of measure
and the numeric values. Press
to scroll through the
options:
oz
:select for non-metric mass units
l
:select for metric volume units
g
:select for metric mass units
in³
:select for non-metric volume units
Press
to move one position to the left and select the
totalizer unit of measure. Refer to the tables on the
previous page for available options. Once the unit is
selected, press
twice to set the decimal location.
Press
to scroll through the decimal location options
of:
00001
001.0
01.00
1.000
These options represent the decimal location of the
totalizer as it will display on the main screen.
Imp1=
represents the volume corresponding to each
pulse of digital output 1 from the controller and is only
displayed if
Out1
is set to one of the three “
#1 IMP
”
options. There are three fields to set for
Imp1=
:
1. Unit of Measure
2. Type of Unit
3. Numeric Value
Press
to access these fields. Press
to move
the cursor to the blank space between the unit of measure
and the numeric values. Press
to scroll through the
options:
oz
:select for non-metric mass units
l
:select for metric volume units
g
:select for metric mass units
in³
:select for non-metric volume units
Press
to move one position to the left and select the
unit of measure. Refer to the tables on the previous page
for available options. Once the unit is selected, press
twice to set the numeric value corresponding to the
volume per number of pulses.
Programming Functions
Press
to scroll each location through 0-9. To move
the decimal point, move the cursor to the decimal point
and press
to move the decimal point to the right. To
move the decimal point to the left, place the cursor on
the decimal point and press
.
Tpul1=
is the duration of the output pulse for output 1
from the controller. This is only displayed when
Out1
is
set to one of the three “
#1 IMP
” options. This setting is
measured in milliseconds (ms) and must be between 0.40
and 9999.99 ms.
Press
to access the field for pulse duration. Use
the
and
keys to scroll through each location to
set the pulse duration. The decimal location cannot be
changed in this field.
NOTE:
Since the instrument can’t detect which type of
device it is connect to, it is up to the user to verify that
the pulse duration is compatible with the external device
processing the pulses. If, for example, an electro-
mechanical pulse counter is connected, two kinds of
problems may occur:
•
If the pulse is too long the totalizer coils may burn
out.
•
If the pulse is too short, the counter may not read
the input pulse and damage to the converter output
may result.
Imp2=
, and
Tpul2=
are programmed in exactly the same
way as
Imp1=
and
Tpul1=
. These two options will only
appear on the display when
Out2
is set to one of the “
#2
IMP
” options.
NOTE
: If
Imp1
and
Tpul1
are set too high, the converter
will attempt to output more pulse signals than is possible
in the available time. The result is that the signal output
will continue after after the registers stops to allow the
pulses to “catch up”.
