4-20 mA Output
The 4-20 mA output from the meter can either be powered from the
meter’s internal transmitter power supply, (if it is not being used to
power the input loop), or by an external power supply as the follow-
ing diagrams illustrate:
Figure 10: Meter Powering 4-20 mA Output Loop
Figure 11: External Power Supply Powering 4-20 mA
Output Loop
If the output loop is powered by an external supply, the loop
power supply must be turned on before the meter is turned
on. Otherwise, the output loop signal may be incorrect.

Programming
Overview
The meter is programmed using the ENTER button and three jumper
arrays.The ENTER button controls the meter’s
S ingle B utton S caling
(SBS) feature that allows the meter to be completely programmed
using just one button.The jumper arrays are used for programming
the input signal, lockout, relays acknowledge enable and relays fail-
safe operation.
Single Button Scaling (SBS)
S ingle B utton S caling is a technique that allows the meter to be com-
pletely programmed using just the ENTER button.The general
method behind
(SBS) is to push ENTER when the meter reads the
desired value.This value may be a menu title, the entire display or
just a single digit. If the meter is not reading the desired value wait
and the value will change. When the meter finally reads the desired
display push ENTER to accept it.
When the meter is first powered up, it will read a random number.
Pushing ENTER will cause the meter to scroll through the following
menu titles (if the Lockout Jumper is not installed):

Five Basic Digit/Display-setting Instructions
Rather than repeat the S ingle B utton S caling (SBS ) technique for
every function it is used in, it will be detailed here and the user can
refer to it when necessary.
The
S ingle B utton S caling technique is used to program all the
meter's functions that require numbers to be entered. For instance,
calibration and scaling values, Low-flow Cutoff values, alarm set and
reset points, 4 and 20 mA output values are set using
(SBS).
1. If the flashing display is OK, push ENTER before it stops flashing
to accept it. (Whenever a new value is to be programmed or Most
Significant Digit has been accepted the entire display flashes, if
this is the desired value, press ENTER before it stops flashing to
accept it.)
2. If the flashing display is not OK, (or if ENTER was not pushed in
time to accept it), wait for Least Significant Digit (LSD) to flash.
3. If a flashing digit is OK, push ENTER before it starts to scroll to
accept it.
4. If a flashing digit is not OK, (or if ENTER was not pushed in time
to accept it), wait for the digit to scroll and push ENTER when OK.
5. Digits will scroll until ENTER is pushed. When a digit is accepted
by pushing ENTER, the next digit to the left flashes.
Basic Meter Programming
Overview
There are four steps for programming the basic meter functions:
1. Select Input
2. Perform Initial Calibration if Needed
3. Select Calibration Method
4. Calibrate or Scale the Meter
Programmed Parameter Values
To simplify programming, the user should write down the desired
programming values prior to attempting to program the meter.The
form located at the back of this manual provides a convenient method
to record the user settings.

Select Input Signal
The meter can be programmed to accept current or voltage input
using the Signal Input Selection Array.This jumper array is located at
the rear of the instrument, next to the screw terminal block. Remove
jumper J3 (if installed) to disable Lockout feature.
Table 1: Signal Input Selection Array
Initial Calibration with External Source (If Needed)
Initial calibration is required only when the I-CAL feature is to be used
with an input other than the default input of 4-20 mA. For best results,
allow the meter to warm up for at least 30 minutes.
1. Program the Signal Input Selection Array for desired input per
Table 1 above.
2. Apply power with ENTER and ACK buttons pushed. Release when
display stops flashing.
3. The meter scrolls through the choices 20, 5, and 10. Which
corresponds to input signals of 4-20 mA, 0-5V or 1-5V, and 0-10V.
Push ENTER when desired value appears.
4. The meter flashes InPt 1. Apply low end signal, (4 mA or 0 V)*,
push ENTER.
5. The meter flashes
InPt 2 . Apply high end signal, (20 mA, 5V,
10 V), push ENTER.
6. This completes the Initial Calibration and initializes INPUT 1 and
INPUT 2 scaling points to 4.000 & 20.000 mA, 0.000 & 5.000 V, or
0.000 & 10.000V.
7. Refer to I-CAL scaling below for further instructions.
*For 1-5 V input signals, calibrate the meter with input1=0 V,
input 2=5 V.

Select Calibration Method
The meter may be calibrated using an external signal source such as a
calibrator (E-CAL), or scaled using the internal source (II-CAL).With
I-CAL, a 4-20 mA input can be scaled for any display range without
applying a signal.To scale inputs such as 0-5V, 1-5V or 0-10 V without
applying a signal, it is necessary to first complete an Initial Calibration,
see Initial Calibration with External Source (If Needed) on page 20.
Scale or Calibrate the Meter
To select a Calibration Method, apply power with ACK button pressed .
1. When display stops flashing, release ACK button. Display
alternates between E-CAL and I-CAL.
2. To calibrate meter with an external source, such as a calibrator,
press ENTER when E-CAL appears.
3. To scale meter with internal source, press ENTER when I-CAL
appears.
Select Decimal Point (dECPt)
To program the decimal point or light up the extra "0", push ENTER.
The meter displays SCALe or Calib, then dECPt. Push ENTER when
dECPt appears.The meter then reads 199990 with the decimal point

General Calibration/Scaling Instructions
Calibration is performed from the front panel using the ENTER but-
ton. It does not require any tools or disassembly of the meter. A
calibrated signal source is required if external calibration (E-CAL) is
selected.
For best results, allow meter to warm up for at least 30 minutes.
The calibration input signals must be within the range of the meter
and input 2 must be greater than input 1. (However, display for input
2 does not have to be greater than desired display for input 1.)
An Error message will appear if input 1 signal and input 2 signal are
too close together:

Select Square Root Extraction (L or S)
With the square root extraction function activated, the meter takes the
square root of the input signal (the output from a differential pressure
transmitter) and displays flow rate.The square root extraction feature
is calibrated using the same
S ingle B utton S caling technique that is
used for two-point linear calibration. Calibration involves setting only
three points: the zero flow rate (usually zero), the high flow rate and
the Low-flow Cutoff point.
To program the meter for square root extraction, push ENTER.When
(L or S) appears, push ENTER again.The meter will flash (L or S)
alternately. Push ENTER when (S) is flashing. After (S) has been
selected the meter will switch to indication mode and is ready to be
calibrated.
Program Low-flow Cutoff (CvtoFF)
Low-flow Cutoff allows the meter to be programmed so that the often
unsteady output from a differential pressure transmitter at Low-flow
rates always displays zero on the meter.
Example: If Low-flow Cutoff is set at 12, any rate less than 12 will be
displayed as "0".
To program Low-flow Cutoff:
1. Push ENTER, when CvtoFF appears push ENTER again.
2. Set Low-flow Cutoff per
Five Basic Digit/Display-setting
Instructions
on page 19.
Notes:
1. To disable Low-flow Cutoff, program cutoff value to zero.
2. Low-flow Cutoff is only available when using Square Root
Extraction.

Alarm Programming
Overview
The meter is equipped with four alarm points as a standard feature.
Each alarm may be programmed for either a high or low alarm and
for 0-100% deadband. Front panel LEDs indicate alarm status.
Options for two or four relays are available.
To program a high alarm, program the set point above the reset point.
To program a low alarm, program the set point below the reset point.
To program the alarm deadband, set the reset point above or below
the set point by an amount equal to the desired deadband value.
Example: Alarm 2 is a high alarm that trips at 1500 and has a dead-
band of 100. Alarm 2 set point is set at 1500 and its reset point at
1400.
Setting Alarm Set & Reset Points (Alars)
Alarm Set and Reset points are programmed using the Five Basic
Digit/Display-setting Instructions
described on page 19.
1. Push ENTER and when ALArS appears, push ENTER again.This
starts a scan of the four alarm set & reset points.The scan
sequence begins with a flashing display of alarm #1 set point.The
"1" LED and "S" LED below the display are illuminated to indicate
the meter is flashing alarm #1 set point value. Program the desired
value for alarm #1 set point using the
Five Basic Digit/Display-
setting Instructions
described on page 19.
2. After Alarm #1 set point has been programmed, the meter displays
Alarm #1 reset point, as indicated by the "1" LED and "R" LED
below the display. Program the desired value for alarm #1 reset
point using the
Five Basic Digit/Display-setting Instructions
described on page 19.
3. Program the remaining alarm set and reset points in a similar
fashion.
4.
When alarm programming is complete the meter will display the
process input signal and the front panel LEDs will indicate alarm
status.
Isolated 4-20 mATransmitter Output Programming (ovtpvt)
The Isolated 4-20 mATransmitter Output option can be programmed
without a calibrator.This option can be calibrated so that a 4 mA out-
put is produced for any number displayed by the meter.The 20 mA
output may be programmed to correspond to any number that is at
least 501 counts greater or smaller than the number corresponding to
4 mA. (Ex. 4 mA = 0, 20 mA = 501 or -501) If the span between 4 and
20 mA is less than 501 counts, an error message will appear and the
previously programmed values will be retained in memory until a
new set of values is accepted.
Setting 4 mA OutputValue
1. Push ENTER, when ovtPvt appears push ENTER again.
2. All digits flash for 3 seconds, a green LED labeled "4" illuminates
indicating the flashing display is the value at which the meter will
produce a 4 mA output. Program desired value per
Five Basic
Digit/Display-setting Instructions
on page 19.
Setting 20 mA OutputValue
1. When ENTER is pushed to complete the programming for 4 mA
output, the green LED labeled "20" illuminates indicating the
flashing display is the value at which the meter will produce a 20
mA output.
2. Program desired value per
Five Basic Digit/Display-setting
Instructions
on page 19.
3. An Error message will be displayed if the 4-20 mA output span is
smaller than 501 counts.
Programming Confirmation
The values that have been programmed to produce the 4 & 20 mA
outputs can be quickly checked to make sure they are the desired val-
ues.To do this, enter the ovtPvt routine by pushing ENTER and then
pushing ENTER again when ovtPvt appears.
The green "4" LED illuminates indicating the meter is displaying the
value at which it will produce a 4 mA output. Confirm that this is the
desired value. Push ENTER (within 3 seconds) before the entire dis-
play stops flashing and the green "20" LED illuminates indicating the
meter is displaying the value at which it will produce a 20 mA output.
Confirm that this is the desired value. Push ENTER (within 3 seconds)
before the entire display stops flashing and the meter returns to indi-
cation mode.

Programming Confirmation
To verify that the alarm set and reset points have been programmed
as desired, push ENTER, and push ENTER again when ALArS
appears. Before the display stops flashing #1 set point value, push
ENTER again to advance the display to #1 reset point. Continue
skipping through the remaining alarm set and reset points.To alter an
alarm point value, wait for the first digit to flash and program the
desired value using the
Five Basic Digit/Display-setting Instructions on
page 19.
Alarm Operation
When the meter detects an alarm, a front panel LED illuminates to
indicate which alarm point has tripped.This LED will stay illuminated
until the meter display passes through the reset point.
Set Relays for Fail-safe Operation
In the fail-safe mode, the relay coils are energized and the Normally
Open (NO) contacts are connected to the Common (C) contacts under
normal operation. During an alarm condition, the relay coils are
de-
energized,
the Normally Closed (NC) contacts are connected to the
Common (C) contacts. During a power failure the relay contacts
reflect an alarm condition.

Alarm Acknowledgment
The ACK button on the front panel resets the optional relays only and
has no effect on the alarm status LEDs.
Automatic & Manual Reset Programming
There are two ways to reset the relays:
1. Automatically when the signal passes through the reset point.
2. Automatically + manually via the front panel ACK button, or a user
supplied momentary Normally Open push-button across terminals
AK and CM at the rear of the instrument.That is, a relay may be
manually reset prior to the signal passing through the reset point
or it will automatically reset when the signal passes through the
reset point.
A manual reset will reset all relays that are programmed for
automatic + manual reset.
Figure 15: Relay Reset Jumpers
An array of jumpers located behind the front panel on the Display
PCB is used to program each relay for either automatic or automatic +
manual reset. Refer to page 32 for front panel removal instructions.
The top jumper is used for relay 1, the next for relay 2, etc. A relay
will automatically reset if no jumper is installed. A relay will automati-
cally reset, plus can be manually reset, if a jumper is installed over its
respective pins.
Example Above: Relay 1 is programmed for automatic reset;
Relays 2, 3, & 4 are programmed for automatic + manual reset.

LowVoltage DC Loads
Figure 17: Low Voltage DC Loads
Use a diode with a reverse breakdown voltage two to three times the
circuit voltage and forward current at least as large as the load cur-
rent.
RC Networks
Suppressors are available from FLOWLINE and should be applied to
each relay that switches an inductive load.
Lockout Jumper
Once the meter has been completely programmed, a lockout jumper
can be installed to restrict further modification to the meter.This
jumper is located at the rear of the instrument and is labeled J3.
When ENTER is pushed with the lockout jumper in place, only ALArS
and ovtPvt routines are displayed.These routines may be entered to
view their settings, but the settings may not be altered.
SWITCHING INDUCTIVE LOADS
The meter has the ability to suppress electrical noise generated by
switching inductive loads. However, installing Resistor Capacitor (RC)
Networks improves this performance and prolongs the life of the
meter's relay contacts.This suppression can be obtained with RC
networks assembled by the user or purchased as a complete assembly.
Refer to the following circuits for RC network assembly and installation:
AC & DC Loads
Figure 16: AC & DC Loads
Choose R and C as follows:
R: 0.5 to 1 ohm for each volt across the contacts
C: 0.5 to 1 microfarad for each 1 A through closed contacts
Notes:
1. Use capacitors rated for 240VAC.
2. Snubbers may affect load release time of solenoid loads, check to
confirm proper operation.
3. Install the RC network right at the meter's relay screw terminals. An RC
network may also be installed across the load.
