INTRODUCTION
This instrument is an analog input process meter with flow rate, totalizer, and
batch control capabilities housed in a rugged, die-cast aluminum NEMA 4X
enclosure. It accepts the common process signals such as 4-20 mA, 0-5 VDC,
1-5 VDC, and 0-10 VDC. It displays these signals in engineering units on a 2.3"
high 4½ digit LED display. The meter also provides two isolated 24 VDC power
supplies to drive both the input and output loops. Options include up to 4 relays
for alarms or batch controlling as well as an isolated 4-20 mA transmitter output.
Features
This model contains several features of interest:
• Two 24 VDC Isolated Transmitter Power Supplies
• 115 or 230 VAC Field Selectable Power
• Rate Display in Units per Day, in Addition to Second, Minute, and Hour
• Programmable Set points for Latching and Non-Latching Relay Operation
• Built-in Snubbers on Each Relay Contact
• Any Set Point Programmable for Process/Rate or Total
• Quit or Exit Menu Scroll with ACK Button
• Pump Alternation Control Feature for Rate Relays

displayed.
Totalizer “rolls over” when display exceeds 999,999. Relay
status reflects display.
Up to four, user selectable under setup menu Setup. Any set
point can be assigned to total and may be programmed
anywhere in the range of the meter.
Relays assigned to total can be programmed to trip at any
point below the next relay’s preset value.
If the meter is programmed to reset total to zero automatically
when the highest preset is reached, then a delay will occur
before the total relays reset. This delay can be programmed
anywhere from 1 to 999 seconds.
This feature allows the user to quickly change preset values
without going into the main menu by holding the ENTER
button for more than 3 seconds.
Via front panel ENTER button, external contact closure, or
automatically via user selectable preset value.
Meter may be programmed so total cannot be reset from front

When power is applied, relays assigned to total will reflect the
state of the accumulated total value in memory. Relays
assigned to process/rate will reflect the state of the input to the
meter.

corresponding to 4 mA. (Ex. 4 mA = 0, 20 mA = 501) If the

Programmed Parameter Settings
To simplify programming, write down the desired programming values prior to
attempting to program the meter. The Programmed Parameter Settings form
located at the back of this manual provides a convenient method to record the
user settings; it also provides the factory setting for most of the programmable
parameters.

Disassembling the Meter
To perform the steps described above, it is necessary to partially disassemble
the meter. Main Board may remain attached to enclosure’s base even during
conduit hub installation if proper precautions are taken.
1. Loosen the four screws that hold the enclosure’s cover in place and remove
cover.
2. Loosen the top three mounting screws holding the Display Board
(see Figure 1).
3. Remove the bottom three mounting screws.
4. Slide the Display Board out from under the top three screws. The ribbon
cable to the Display Board may be removed during meter installation. Do
not remove standoffs from Main Board. The Main Board is secured to
enclosure’s base with four mounting standoffs.
5. Change voltage selection as required, described on page 20. Set
configuration jumpers; connect power and signal wires.
6. Reassemble the Display Board prior to applying power.
7. To program meter using front panel buttons leave top cover off until meter
programming is complete.
8. Install lockout jumper to prevent accidental changes to programmed
settings.
Reassembling the Meter
After the wiring and jumper selections have been made, reassemble the Display
Board.
1. Slide the Display Board under the top three screws (see Figure 1). Make
sure the ribbon cable is connected to the connector on the Display Board.
2. Replace the bottom three mounting screws.
3. Fasten the top three mounting screws.
4. Align the enclosure cover so the alarm numbers on the cover are on the left
side of the unit and aligned with the alarm status LEDs.
5. To program the meter using the front panel buttons leave top cover off until
meter programming is complete.
6. Replace the enclosure cover and fasten the four screws that hold it in place.

Jumper Configuration
Overview
Before programming the meter, it is necessary to configure three jumper arrays.
The jumper arrays are used for setting the type of input signal (4-20 mA, 0-5 V,
or 0-10 V); locking out the programmed settings, enable relay acknowledgement
(ACK), and setting relay fail-safe operation.

Power Selection
Overview
Power Selection involves the following:
1. Changing to 230 VAC power if needed. Factory default is 115 VAC.
2. Labeling the meter as to how it will be powered: 115 VAC, 230 VAC, or
24 VDC. Meters powered from 24 VDC are labeled as such at the factory.
Note: Meters ordered to operate from 24 VDC do not require any special setup,
this option is not field selectable.
All AC powered meters are shipped from the factory set for
!
!
!
115 VAC power. Do not apply 230 VAC without first setting up the
meter to accept this voltage.
Disconnect power prior to performing the following procedures.
The meter is field selectable for either 115 VAC or 230 VAC power.
Changing the voltage selection involves the removal of the front
cover and the Display Board, then selecting 115V or 230V on
switch S1 located on the Main Board.
Observe polarity for DC powered meters. Applying voltage with
reverse polarity may damage the meter.
Do not apply an AC voltage to DC powered meters. Applying an
AC voltage to DC powered meters will result in damage to the
meter and endanger personnel.
Changing from 115 to 230 VAC Power
To access the 115/230 VAC switch it is necessary to remove the housing cover
and the Display Board, see Disassembling the Meter, page 18.
Once the Display Board has been removed, switch S1 is visible
black component with a red slide switch on the top, located next to the
transformer. For location see Figure 3, page 21.
For 115 VAC operation, the switch shows 115V; for 230 VAC it shows 230V.
Several setup steps are required and connections made while the Display Board is
removed, so it should not be reinstalled just yet. However, to avoid electric shock,
install the Display Board prior to applying power.

Programming
Overview
The meter is programmed using the ENTER button and three jumper arrays. The
ENTER button is used to calibrate the meter, program various totalizer functions,
and set alarm trip and reset points. The jumper arrays are used for programming
the input signal, lockout, relays acknowledge enable, and relays fail-safe
operation. This section of the manual deals with programming the following
aspects of the meter:
• Basic Meter
• Process/Rate Meter
• Totalizer
• Batch Controller
• Relays
• 4-20 mA Output
• Lockout and Display Selection
General Programming Description
All programming is performed using the ENTER button. To set up a function
there are sequential steps that have to be performed. As each step progresses,
either a single digit or the entire display will flash. The flashing digit, or flashing
display, will be looking for acknowledgement if it is the desired di git or display.
Pressing the ENTER button will accept the value. If the flashing display or digit is
not the one desired, wait and the value will change.
Each digit will flash for 3 seconds before it starts to change, when it is accepted
the next digit will flash for 3 seconds. This procedure will continue until the
ENTER button is pressed while the desired option is flashing. As the
programming progresses there will be times when a decision has to be made, an
example is yes or no ( y or n ).
ENTER and ACK Functionality
The ENTER button is used to program the meter for various functions.
The ACK b utton is used to acknowledge the relays during operation and to quit
main menu scroll during programming, diagnostic menu, and calibration.

ENTER Button
The ENTER button is used to program the meter for various functions and is
located behind the front panel on the Display Board, It is labeled SW2 in Figure

pushbutton switch across terminals EN and CM on connector J1 located on the
Main Board (see Figure 3, page 21).
