An error message will appear if the input 1
and input 2 signals are too close together.
Input
Impedance
Voltage ranges: greater than 500 k
Current ranges: 50 - 100
(depending on
internal resettable fuse impedance)
Input
Overload
Current input protected by an internal
resettable fuse, 30 VDC max. Fuse resets
automatically after fault is removed.
HART
Transparency
The meter does not interfere with existing
HART communications; it displays the
4-20 mA primary variable and it allows the
HART communications to pass through
without interruption. The meter is not
affected if a HART communicator is
connected to the loop. The meter does not
display secondary HART variables.
Rate/Totalizer
Rate Display
Indication
-99999 to 999999, lead zero blanking.
“R” LED illuminates while displaying rate.
Total Display
& Total
Overflow
0 to 999,999; automatic lead zero blanking.
“T” LED is illuminated while displaying total
or grand total.
Up to 999,999,999 with total-overflow
feature. “
oF

overflow and
▲ LED is illuminated.
Total
Decimal Point
Up to five decimal places or none:
d.ddddd
,
d.dddd
,
d.ddd
,
d.dd
,
d.d

Total decimal point is independent of rate
decimal point.
Totalizer
Calculates total based on rate and field
programmable multiplier to display total in
engineering units. Time base must be
selected according to the time units in
which the rate is displayed.
Totalizer
Rollover
Totalizer rolls over when display exceeds
999,999,999. Relay status reflects display.
Total
Overflow
Override
Program total reset for automatic with
0.1 second delay and set point 1 for
999,999
Totalizer
Presets
Four, user selectable under setup menu.
Any set point can be assigned to total and
may be programmed anywhere in the
range of the meter for total alarm
indication.
Programmable
Delay
On Release
0.1 and 999.9 seconds; applied to the first
relay assigned to total or grand total.
If the meter is programmed to reset total to
zero automatically when the preset is
reached, then a delay will occur before the
total is reset.
Total Reset
User selectable via front panel button, F4
terminal at back of meter, external contact
closure on digital inputs, automatically via
user selectable preset value and time
delay, or through serial communications.
Total Reset
Password
Total and grand total passwords may be
entered to prevent resetting the total or
grand total from the front panel.
Non-Resettable
Total
The grand total can be programmed as a
non-resettable total by entering the
password “050873”.
•
Once the Grand Total has been programmed as
“non-resettable” the feature
CANNOT
be
disabled.
