Range
Input Range Minimum Span
Input 1 & Input 2
4-20 mA
0.15 mA
10 V
0.01 V
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
resettable fuse impedance)
Input
Overload
Current input protected by resettable fuse,
30 VDC max.
Fuse resets automatically after fault is
removed.
F4 Digital Input
Contacts
3.3 VDC on contact. Connect normally
open contacts across F4 to COM.
F4 Digital Input
Logic Levels
Logic High: 3 to 5 VDC
Logic Low: 0 to 1.25 VDC
HART
Transparency
Analog input will not interfere with existing
HART communications on the wired 4-20
mA signal
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
” is displayed to the left of total
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
,
or
dddddd
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
Up to eight, 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
Via front panel button, 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”.
Caution!
Once the Grand Total has been
programmed as “non-
resettable” the feature
cannot
be disabled.
Relays
Rating
4 SPDT (Form C) internal and/or 4 SPST
(Form A) external; rated 3 A @ 30 VDC
and 125/250 VAC resistive load; 1/14 HP
(
≈
50 W) @ 125/250 VAC for inductive
loads
Noise
Suppression
Noise suppression is recommended for
each relay contact switching inductive
loads; see page 19 for details.
Relay
Assignment
Relays may be assigned to rate, total, or
grand total.
Deadband
0-100% of span, user programmable
High or Low
Alarm
User may program any alarm for high or
low trip point.
Unused alarm LEDs and relays may be
disabled (turn off).
Relay
Operation
Automatic (non-latching) and/or manual
reset
Latching (requires manual acknowledge)
with/without clear
Pump alternation control (2 to 4 relays)
Sampling (based on time)
Off (disable unused relays and enable
Interlock feature)
Manual on/off control mode
Relay Reset
User selectable via front panel buttons,
digital inputs, or PC
1. Automatic reset only (non-latching),
when the input passes the reset point
or total is reset to zero.
2. Aut manual reset at any time
(non-latching)
3. Manual reset only, at any time
(latching)
4. Manual reset only after alarm condition
has cleared (latching)
Note: Front panel button or digital input
may be assigned to acknowledge
relays programmed for manual reset.
Time Delay
0 to 999.9 seconds, on & off relay time
delays
Programmable and independent for each
relay.
Fail-Safe
Operation
Programmable and independent for each
relay.
Note: Relay coil is energized in non-alarm
condition. In case of power failure,
relay will go to alarm state.
