Introduction
The Loop Leader+ loop-powered large display flow
rate/totalizers can be installed virtually anywhere to
provide convenient and informative display of any
4-20 mA signal. One of the most convenient features of
these instruments is their large, dual-line display which is
typically used to display flow rate on the 2.8" 5-character
alphanumeric top display and flow total, flow grand total,
or a tag on the 1.5" 8-character alphanumeric bottom
display. Both display lines use 14-segment,
alphanumeric characters that provide much clearer
indication of tags, units, or alarm messages than
7-segment characters do.
Further enhancing the display on these instruments is
a 20-segment bargraph that also includes a numeric
value of the percentage the bargraph represents.
These flow rate/totalizers can be installed virtually
anywhere because they get their power from the
4-20 mA loop and therefore require no separate
power source, and they only drop 2.1 V, so they add
very little burden to the loop. Additional features that
allow these instruments to be installed virtually
anywhere include a NEMA 4X, IP65 rated enclosure,
an operating temperature range of -40 to 167°F (-40
to 75°C) (for safe area products), conformally coated
PCBs, and a backlit LCD that can be read in bright
sunlight or dimly lit areas. The PD4-6628 model is an
intrinsically safe and nonincendive version of the Loop
Leader+ that is agency approved for installation in
hazardous areas. It also carries electrical safety
approvals.
Free, PC-based, MeterView XL software that
connects to the meter via a micro USB cable is
available for programming and setup of the meters.
To download the latest MeterView XL programming
software and manual, visit predig.com/meterviewxl.
All models come equipped with two open collector
outputs and remote contacts. There are also models
available with two solid-state relays and isolated
4-20 mA analog output options. The open collector
outputs are useful for alarm indication or pulse output.
The remote contacts can be used to remotely operate
the four programming buttons, to reset the total, to
start/stop a timer/stopwatch, and more. The relays
can be programmed for alarm indication, on/off
control, or simple batch control.

Key Features
1. Available on PD4-6624 only. Requires external 24 VDC power.
2. Backlight requires external 24 VDC power.
Large Informative Display
One of the most convenient features of the PD4 Loop
Leader+ Series is its large, dual-line display. The
PD4’s whopping 2.8" 5-character alphanumeric top
display and 1.5" 8-character alphanumeric bottom
display, plus a 20-segment bargraph with percentage
indication on top, makes reading and understanding
process values easier than ever.
Predefined display units give users even more display
flexibility. Plus, the high contrast backlit LCD display
is readable from far away and under various lighting
conditions.
Backlight Turns Red on Alarm
When an alarm occurs, the display can be
programmed to turn red and flash. In addition, a
unique custom alarm message for each of the two
relays and two open collectors can be displayed on
the bottom display. These features can be activated
even if no relay or open collector is connected.
Commas on 8-Digit Totalizer for
Easy Reading
It may seem like a simple thing, but adding commas
to an eight-digit number makes it easier to read:
Dual-Scale Feature
Users can use the dual-scale feature to display
the input in two different scales. For instance, the
example below shows an application where the Loop
Leader+ displays the input in gallons per minute and
cubic feet per minute.
14-Segment Characters
Notice how much better letters like “T”, “N” and “K”
appear as 14-segment characters on the Loop Leader+
vs 7-segment characters found on many other meters.

Predefined and Custom Units
The PD4-6624/28 flow rate/totalizers have the most
common predefined rate and volume units. If the
desired unit is not available, the user can program a
custom unit.
• If the total is disabled in the System – Total
menu, the meter has six available
preprogrammed unit classes: volume, height,
temperature, pressure, weight, and rate. When
the desired unit class or unit of measure within a
class is not available, a custom unit may be
programmed.
Password Protection
A password can be set up for programming security to
prevent unauthorized changes to the programmed
parameter settings.
Remote Contacts
Remote Contacts are standard on the PD4 and the
meter can be operated via a remote control station
(PDA2364-MRUE). The PDA2364-MRUE mimics the
PD4 meter’s four programming buttons: Menu, Right
Arrow, Up Arrow, and Enter.
Multiple Outputs
• Two open collector outputs (standard)
• Two solid-state relays (optional)
• One 4-20 mA output (optional)
The open collector outputs and relays generally
operate in the same manner, with the major exception
being the open collectors are not available for pump
alternation and the relays are not available with pulse
features. The open collectors and relays can be
controlled either automatically or manually.
The isolated analog output signal can be configured
to represent the process variable (rate, total, or
retransmit). It can also be reverse scaled such that
the meter’s high calibration value outputs 4 mA and
the meter’s low calibration outputs 20 mA.
Input Signal Conditioning
Functions (FUNCTION)
The Function menu is used to select the input signal
conditioner applied to the input: linear, square root,
programmable exponent, or round horizontal tank
volume calculation. Multi-point linearization is part of
the linear function selection.
Meters are set up at the factory for linear function with
2-point linearization. The linear function provides a
display that is linear with respect to the input signal.
Square Root Linearization (SQROOT)
The square root function can be used to linearize the
signal from a differential pressure transmitter and
display flow rate in engineering units.
PD4-6624 Displaying Flow Rate by Applying the Square
Root Function to the Output of a DP Transmitter.
Programmable Exponent
Linearization (EXPONENT)
The programmable exponent can be used to linearize
the signal from level transmitters in open-channel flow
applications using weirs and flumes.
The PD4-6624, in combination with an ultrasonic level
transmitter, makes for an economical way to measure
and display open channel flow rate in most weirs and
flumes. A guide such as the ISCO Open Channel
Flow Measurement Handbook can provide the user
with all the information needed: the exponent used in
the flow equation for the desired flow units and the
flow rate for any given head height. For example, to
display the open channel flow rate from a 3" Parshall
flume, the ISCO handbook advises the exponent is
1.547 and at the maximum head height of 3.0 feet,
the flow rate is 3.508 MGD.

Rate/Totalizer Features
Display Flow Rate & Total at the
Same Time
The PD4-6624 can display flow rate and total at the
same time. In addition, the meter can toggle between the
rate and total and their corresponding units as the
following example illustrates.
Total Limit & Initial Value
The Advanced – Total Count menu allows the digit limit
to be selected between 8-digit (bottom display only) and
13-digit (uses top and bottom display to display the full
number).
The user can set the initial value at which the total and
grand total should start counting.
Using 13 Digits to Display Total
The top and bottom displays can be set up to display
a 13-digit total.
Note: The number above should be read as
6,843,276,349,187.
Total & Rate in Different Units
The user can select to display total in different units
than the rate. For instance, a customer could
measure flow rate in gallons per minute and total in
acre-feet by simply selecting AF (acre-feet) units for
the total. Additionally the user can enter a custom unit
and conversion factor to display the total in any unit of
measure.
Rate in Units Per Second, Minute,
Hour, or Day
The user may select a rate time base in units per
second, minute, hour, or day. The time base is the
amount of time over which the rate parameter will
totalize. For example, if the rate was 10 gallons/min
(and stayed constant for one minute), then the total
would increase by 10 every minute.
4-20 mA Output for Rate or Total
The 4-20 mA output can be assigned to the rate or
total.
Total Stored in Non-Volatile
Memory
Total and grand total values, and all programmed
settings are stored in non-volatile memory for a
minimum of ten years if power is lost.
Total Reset Capabilities
The total and grand total can be reset using a button
behind the lower panel door, the remote contacts
connected to a control station, an external contact
closure on the digital input, or MeterView XL. In
addition, both total and grand total reset can be
password protected to prevent unauthorized resets.
Total Reset via Button Under
Lower Panel Door
The PD4-6624 is equipped with four buttons located
under the lower panel door. The F2 function key is set
up to reset the total. If reset grand total is enabled, it
is possible for the user to reset either the total or the
grand total.
Total Reset via Remote Contact
The PD4-6624 is equipped with remote contacts
located behind the lower panel door of the meter.
These can be connected to a PDA2364-MRUE
control station for remote operation of all four
programming / operation buttons. The F2 function key
is set by default to reset the total and grand total.

Total Reset via Digital Input
The PD4-6624’s digital input may also be used to reset
the total or grand total using a PDA2361-R control
station.
Total Reset Password Protection
Total and grand total passwords can be set to prevent
resetting the total or grand total unless a password is
entered. Grand total reset can be disabled through
the meter interface, and it can also be permanently
disabled.
Non-Resettable Grand Total
The user can set up the grand total to be non-resettable by
selecting YES at the PERMLOC menu; see page 59 for
details. Once this is done, the grand total can never be reset.
Batch Control Capabilities
The meter can be equipped with two solid-state relays
that may be set up for batch control. Selecting batch
control for relay 1 enables the batching features on the
meter. The top display changes to show the total and the
bottom display changes to show the batch preset. The
function keys also change for batch control functions
such as F1 starts a batch, F2 opens the preset menu to
allow the preset value to be changed, and F3 stops the
currently running batch. Enabling batch control for
relay 1 allows access to the batch menu under relay 2.
The second relay may be programmed as a preclose
relay or as another batching relay with its own preset
amount.
Manual or Automatic Operation
Batching can be set to either manual or automatic
operation.
If set to automatic, then a delay before the next batch
starts must be programmed.
Count Up or Down Batching
The batch total can be set to count up or down.

Remote Operation of Meter
The meter can be operated remotely by connecting a
PDA2364-MRUE control station to the Remote Contacts
located behind the lower panel door of the meter as
illustrated in Figure 16. PDA2364-MRUE Control
Station Connected to Remote Contacts on PD4.
Note: The control station does not carry hazardous area
approvals and thus is not suitable for location in hazardous
areas. The use of additional protective devices may allow it
to be installed in a safe area and connected to a device in a
hazardous area. User should consult a professional engineer
to determine suitability of this product for their specific
application.

Setup and Programming
Overview
There are no jumpers to set; setup and programming
is done by using the buttons (MENU, NEXT, UP,
ENTER) located behind the lower panel door of the
meter or PC-based software.
The meter may be powered via the USB connection
located behind the lower panel door of the meter for
the purposes of programming only. The backlight
requires an external power source. If the meter is
powered from the USB, the backlight will only work if
it is powered separately from a DC supply.
MeterView XL Programming Software
The meter can also be programmed using PC-based
MeterView XL software. This software greatly
simplifies the programming process and allows the
user to save configuration files for later use.
The meter connects to the PC via a provided microUSB cable and is powered by the USB connection so
no additional power is needed during programming.
To download the latest MeterView XL programming
software and manual, visit predig.com/meterviewxl.
• The meter should only be connected to a computer
while it is located in a safe area.
• The image in the software shows the panel meter
version. The same software is used for the PD4.
• Care should be exercised to avoid ground loops
when connecting the USB to an active loop (e.g.
power supply, transmitter, loop-powered meter,
etc.). It is recommended to connect the (mA+)
terminal of the meter to the (-) terminal of a twowire transmitter and the (mA-) to the (+) of the next
device in the loop or to the (-) terminal of the power
supply.
The meter is factory calibrated prior to shipment
to display 0.00 to 100.00, which corresponds to
the 4-20 mA input. The calibration equipment is
traceable to NIST standards.

Scaling the 4-20 mA Input (INPUT)
It is very important to read the following information before proceeding to program the meter:
• The meter is factory calibrated prior to shipment to display 0.00 to 100.00 gal/s, which corresponds to the
4-20 mA input. The calibration equipment is traceable to NIST standards.
• A calibrated signal source is not needed to scale the meter.
Enter the Input menu to scale the meter to display the 4-20 mA input. The input can accept any signal from
4 to 20 mA.
• Reverse Scaling
The meter can be scaled so that 4 mA represents the high end of the process value range being measured by the
transmitter and 20 mA represents the low end of the process value range.

Scaling Example
The 4-20 mA input can be scaled to the appropriate values for a given application. The 4 mA input (input 1) should
have a corresponding display value (display 1) which represents the low end of the process value range being
measured by the transmitter. Likewise, the 20 mA input (input 2) should have a display value (display 2) which
represents the high end of the process value range.
For example: If the meter is setup to accept a 4-20 mA input and display the flow of a pipe whose rate of flow is
between 0 and 100 gal/s, the transmitter would send a 4 mA signal when there is zero flow and a 20 mA signal when
there is maximum flow. The meter should be programmed to interpret these inputs on a display range of 0-100, so
that at 4 mA the meter will display 0 and at 20 mA the meter will display 100.
Processes which require a non-linear scale can be accommodated using the linear (LINEAR), exponent (EXPONENT),
and square root (SQROOT) functions available in the Advanced menu. See Input Signal Conditioning Functions
(FUNCTION) on page 54.
A signal source is not needed to scale the meter; simply program the inputs and corresponding display values.
Setting the Display Features (DISPLAY)
The meter’s display functions may be programmed using the Display menu. This menu consists of the following
submenus: Units, Decimal Point, Comma, Bargraph, Top, and Bottom.
Changing the Engineering Units (UNITS)
It is possible to change the display units without the need to re-scale the meter. When selecting a new unit from
within the DISPLAY menu (e.g. changing from gallons/sec. (GAL/s) to liters/sec. (L/s)), the meter will automatically
convert the display values to display the new unit. Enter the UNITS menu, select a new unit of measure from the list
of predefined units, and press the Enter button. If entering a custom unit (CUSTM), a custom conversion factor will
need to be entered.
Changing the Decimal Point (DEC.PT)
The decimal point may be set with up to seven decimal places or with no decimal point at all.
Pressing the Right-Arrow moves the decimal point one place to the right until no decimal point is displayed,
and then it moves to the left most position. Pressing the Up-Arrow moves the decimal point one place to the left.
The decimal point location is set independently for the rate, total and grand total.

Open Collector Outputs (OPEN COLLECTR)
The meter is equipped with two NPN open collector outputs that may be set up for pulse outputs, alarms, timed
pulses, total reset, or disabled.
Pulse outputs can be set to transmit the rate, total, or grand total. Output 2 may be used to generate a quadrature
output based on the other open collector output. An output test mode is also selectable to generate pulses at a
constant programmable frequency.
Alarms are available based on the rate value or the digital input. The alarm status will show on the display even if
the output is not wired.
A timer output (TIMER) turns the open collector on and off at the specified time intervals. The timer can be set as
single-shot or continuous timer.
A total reset output generates a pulse whenever the total is reset, regardless of the reset method used. The On time
is programmable between 0 and 9,999 seconds.
The stopwatch output (STPWATCH) allows the open collector to be manually activated by starting the stopwatch. The
stopwatch count can be displayed on the top or bottom display.
The output may be disabled by selecting DISABLE.
The Open Collector Outputs are programmed in the following manner:

Pulse Output (PULSE)
Pulse outputs may be assigned to output the rate, total, or grand total at a programmable factor. If the output is
assigned to rate, the factor is a multiplier that determines the number of pulses generated based on the rate. For
example, if the meter display shows 100 gallons/second and the factor is set to 2, the number of pulses generated
per second would be 200. If the output is assigned to total or grand total, the k-factor corresponds to the number of
pulses generated per unit of measure. For example, if the k-factor is 0.001 and the units are gallons, one pulse will
be generated for every 1,000 gallons. The maximum frequency is 1,000 Hz.
Setting output 2 to quadrature will duplicate the other open collector output, but lag by 90 degrees out of phase. The
other output should be programmed as desired for the quadrature output function and must be a pulse (PULSE)
output selection. The quadrature maximum frequency for both outputs is 500 Hz.
The TEST option will output a fixed number of pulses per second based on the FREQ value entered.

Alarm (ALARM)
Alarm outputs may be assigned to the rate, total, grand total, or the digital input. When assigned to the rate, the alarm
may be set as either a high alarm or a low alarm. Alarm actions (AUTO, AUTO.MAN, LATCH, L-CLEAR) determine how
and when the alarm should be reset. They operate as follows:
• Automatic (AUTO): Alarm will reset automatically once the alarm condition has cleared.
• Automatic/Manual (AUTO.MAN): Alarm will reset automatically once the alarm condition has cleared but can
also be reset using the Enter (ACK) button (or whichever function key is set to acknowledge) at any time.
• Latching (LATCH): Alarm must be reset manually and can be done so at any time. Press the Enter (ACK)
button at any time to clear the alarm.
• Latching with Reset after Clear (L-CLEAR): Alarm must be reset manually and can only be done so after
the alarm condition has cleared. Press the Enter (ACK) button after the alarm condition has cleared to reset
the alarm.
If the alarm is set to rate, a set and reset point must be programmed. The set point is the display value at which the
alarm will turn on and the reset point is the display value at which the alarm will turn off. If the set point is lower than
the reset point, the alarm will be a low alarm; if the set point is higher than the reset point, the alarm will be a high
alarm. The digital input alarm will trigger whenever the digital input is triggered.
For both the rate and digital input alarms, a delay before the alarm is turned on or off may be set, as well as a
fail-safe feature which reverses the on/off operation of the open collectors.
Alarm states will be displayed on the meter even if no open collector output is physically connected. These may
include a red LED backlight, flashing the rate value (rate alarm only), and a programmable alarm message.

Flashing Red Alarm (RED)
The last two lines in the preceding menu flow chart show how to program the display to turn red, flash, and display a
message when an alarm occurs.
Alarm 1 is High Alarm:
Alarm 2 is Low Alarm:
Timer (TIMER)
The timer output may be set to generate the timed pulse only once (ONESHOT) or continuously (CONT).
The timer output produces a constant width pulse at a constant frequency, if set as continuous timer. Program the
Off Delay (OFF.DLAY) from 1 second to 99 hours 59 minutes and 59 seconds. This is the time it takes from selecting
START to turning on the output and for how long the output is off in continuous mode.
Program the On Time (ONTIME) for the active low pulse from 1 second to 99 hours 59 minutes and 59 seconds
(pulse width). This is the period of time for which the output will remain on.
Select Start (START) to begin outputting the constant timed pulse.
Select Stop (STOP) to end outputting the constant timed pulse.
Function keys or the digital input may be assigned to start and stop timer functions (see the USER menu in

Stopwatch (STPWATCH)
The stopwatch function may be used to manually run and control a process for a specific time interval up to 99 hrs,
59 min, and 59 seconds. The stopwatch function may be assigned to any open collector. There are three settings
needed to use the function effectively.
1. Assign stopwatch to either top or bottom display
2. Assign the open collector or relay to control the process (on/off)
3. Assign a function key or digital input to start/stop the stopwatch
Application Example
To maintain consistency of a product, it is necessary to take and test samples at different times throughout the day.
The stopwatch function is used to open and close a solenoid valve to know the exact amount of time needed to
complete the desired sample. Once this is determined, the timer function can be used to automatically take a sample
(batch) based on the time determined using the stopwatch function.
Setup: Assign the following to Stopwatch Function
• Bottom display
(see pages 38 & 40 for details how to change the display)
• Relay 1
(see pages 42 & 47 how to change Open Collector and or Solid-State Relay functionality)
• F3: Start/Stop
(see pages 63 & 64 for details on how to change the function keys)
Procedure
• Press F3 to start the stopwatch; relay 1 turns on and the process starts running.
• Press F3 to stop the stopwatch; relay 1 turns off and the process stops.
• The bottom display indicates the time it took to complete the sample.

Solid-State Relay Outputs (RELAY)
The meter is optionally equipped with two solid-state relays that may be set up for alarms, sample, timer, batch
control, or stopwatch. Alternatively, they may be disabled.
Alarms are available based on the rate, total, grand total, or the digital input. The alarm status will show on the
display even if the output is not wired.
Sample will engage the relay for a programmed period of time when either the total or the grand total have reached
a programmed amount.
A timer output (TIMER) turns the relay on and off at the specified time intervals. The timer can be set as single-shot
or continuous timer.
For use in batch control applications, the meter relays must be set to batch. This will enable the batch control features
of the meter.
The stopwatch output (STPWATCH) allows the relay to be manually activated by starting the stopwatch. The
stopwatch count can be displayed on the top or bottom display.
The output may be disabled by selecting DISABLE.
• During setup, the relays do not follow the input and they will remain in the state found prior to entering the Relay menu.

Alarm (ALARM)
Alarm outputs may be assigned to the rate, total, grand total, or the digital input. When assigned to the rate, the alarm
may be set as either a high alarm or a low alarm. Alarm actions (AUTO, AUTO.MAN, LATCH, L-CLEAR) determine how
and when the alarm should be reset. They operate as follows:
• Automatic (AUTO): Alarm will reset automatically once the alarm condition has cleared.
• Automatic/Manual (AUTO.MAN): Alarm will reset automatically once the alarm condition has cleared but can
also be reset using the Enter button (or whichever function key is set to acknowledge).
• Latching (LATCH): Alarm will not reset automatically even if the alarm condition has cleared. Press the
Enter button at any time to acknowledge the alarm.
• Latching with Reset after Clear (L-CLEAR): Alarm must be reset manually and can only be done so after
the alarm condition has cleared. Press the Enter (ACK) button after the alarm condition has cleared to reset
the alarm.
If the alarm is set to rate, a set and reset point must be programmed. The set point is the display value at which the
alarm will turn on and the reset point is the display value at which the alarm will turn off. If the set point is lower than
the reset point, the alarm will be a low alarm; if the set point is higher than the reset point, the alarm will be a high
alarm. If the alarm is set to total or grand total, only a set point needs to be programmed. The digital input alarm will
trigger whenever the digital input is triggered.
For all alarms, a delay before the alarm is turned on or off may be set, as well as a failsafe feature which will inverse
the on/off programming.
Alarm states will be displayed on the meter even if no relay output is physically connected. The alarm indicator (!)
(only on meters with no bargraph) will display as well as optional red LED backlight, flashing rate, total, or grand total
value (rate, total, or grand total alarms only), and a programmable alarm message.

Sample (SAMPLE)
A relay set to sample will trigger when the total or grand total value has incremented by a programmed amount.
The relay can be programmed to stay on for a specified amount of time.
For example: if a relay is set to sample the total with a COUNT of 1,000 and a TIME of 10 seconds, the relay will
engage for 10 seconds whenever the total has incremented by 1,000 (e.g. 1000, 2000, 3000).
Timer (TIMER)
The timer output may be set to generate the timed pulse only once (ONESHOT) or continuously (CONT).
The timer output produces a constant width pulse at a constant frequency, if set as continuous timer. Program the
Off Delay (OFF.DLAY) from 1 second to 99 hours 59 minutes and 59 seconds. This is the time it takes from selecting
START to turning on the output and for how long the output is off in continuous mode.
Program the On Time (ONTIME) for the active low pulse from 1 second to 99 hours 59 minutes and 59 seconds
(pulse width). This is the period of time for which the output will remain on.
Select Start (START) to begin outputting the constant timed pulse.
Select Stop (STOP) to end outputting the constant timed pulse.
Function keys or the digital input may be assigned to start and stop timer functions (see the USER menu in
Advanced).

Batch Control (BATCH)
Selecting batch control for relay 1 enables the batching features on the meter. The top display is changed to show the
total and the bottom display is changed to display the preset batch amount. The function keys are changed so that F1
starts a batch, F2 opens the preset menu to allow the preset value to be changed, and F3 stops the currently running
batch. Enabling batch control for relay 1 allows access to the batch menu under relay 2 (this menu does not appear
by default).
Batch Control Relay 1
The batch total can be set to count UP or DOWN. The batch MAXIMUM is the max preset amount that can be batched.
Batching can be set to either manual or automatic operation (MANUAL or AUTO). If setting batching to automatic, a
delay before the next batch is started must be programmed. The PRESET amount is the value at which the batch will
stop and can be programmed up to the value assigned in the MAXIMUM menu. An on and off delay may be set for
batching relays.

Batch Control Relay 2
The BATCH option only appears under relay 2 if relay 1 has also been set to batch control. The second relay may be
programmed as a preclose relay or as another batching relay with its own preset amount.
Stopwatch (STPWATCH)
The stopwatch function may be used to manually run and control a process for a specific time interval up to 99 hrs,
59 min, and 59 seconds. The stopwatch function may be assigned to any relay. There are three settings needed to
use the function effectively.
1. Assign stopwatch to either top or bottom display
2. Assign the open collector or relay to control the process (on/off)
3. Assign a function key or digital input to start/stop the stopwatch
Application Example
To maintain consistency of a product, it is necessary to take and test samples at different times throughout the day.
The stopwatch function is used to open and close a solenoid valve to know the exact amount of time needed to
complete the desired sample. Once this is determined, the timer function can be used to automatically take a sample
(batch) based on the time determined using the stopwatch function.
Setup: Assign the following to Stopwatch Function
• Bottom display
(see pages 38 & 40 for details how to change the display)
• Relay 1
(see pages 42 & 47 how to change Open Collector and or Solid-State Relay functionality)
• F3: Start/Stop
(see pages 63 & 64 for details on how to change the function keys)
Procedure
• Press F3 to start the stopwatch; relay 1 turns on and the process starts running.
• Press F3 to stop the stopwatch; relay 1 turns off and the process stops.
The bottom display indicates the time it took to complete the sample.
Runtime & Cycle Count (INFO)
The relay information menu shows runtime and cycle count for each relay. These values may be cleared at any time
by selecting the Clear option (CLEAR?).

Isolated 4-20 mA Output (4-20 mA)
The 4-20 mA menu is used to scale the 4-20 mA output based on display values. This menu is not present on models
without a 4-20 mA output option.
The 4-20 mA analog output (if equipped) can be scaled to provide a 4-20 mA signal for the rate or total display range
or to simply retransmit the 4-20 mA input. The output may be disabled (DISABLE) and will only output the minimum
signal.
Overrange and underrange values determine what mA signal the meter will output if the mA input is underrange
(<3.5 mA) or overrange (>20.5 mA). This value may be set to 1 mA, 3.5 mA, 3.8 mA, 20.5 mA, 20.8 mA, 23 mA,
or disabled.
No equipment is needed to scale the analog output; simply program two display values and corresponding mA output
signals.
Rate or Total (RATE or TOTAL)
To scale the analog output, enter display value 1 and a corresponding analog output value for this display, then enter
display value 2 and a corresponding analog output value for this display value. This will provide a linearly scaled
analog output.
Retransmit (RETRANS)
This option will retransmit the 4-20 mA analog input without the need to scale the output.
Output Manual Control (CONTROL)
The Control menu is used to control the open collector outputs, 4-20 mA analog output, or the relays manually,
ignoring the input. Each open collector, relay, and analog output can be programmed independently for manual
control. Selecting automatic control sets all relays and analog output for automatic operation.
After selecting manual control for a specific output, you can set the output value. To change the output value, return
to the Control menu, select the output to control, select manual control, and enter a new input.

Input Signal Conditioning Functions (FUNCTION)
The Function menu is used to select the input signal conditioner applied to the input: linear, square root, programmable
exponent, or round horizontal tank volume calculation. Multi-point linearization is part of the linear function selection.
Meters are set up at the factory for linear function with 2-point linearization. The linear function provides a display that is
linear with respect to the input signal.
Using MeterView XL
MeterView XL makes programming the input signal conditioning functions quick and easy. Go to the input/scale menu
and select the desired function from the drop down menu in the “scale input” section.

Programmable Exponent Linearization (EXPONENT)
The programmable exponent can be used to linearize the signal from level transmitters in open-channel flow
applications using weirs and flumes.
The PD4-6624, in combination with an ultrasonic level transmitter, makes for an economical way to measure and
display open channel flow rate and total in most weirs and flumes. A guide such as the ISCO Open Channel Flow
Measurement Handbook can provide the user with all the information needed: the exponent used in the flow equation
for the desired flow units and the flow rate for any given head height.
For example, to display the open channel flow rate from a 3" Parshall flume, the ISCO handbook advises the
exponent is 1.547 and at the maximum head height of 3.0 feet, the flow rate is 3.508 MGD.

Advanced Total and Grand Total Setup (ADV TOTAL & ADV GTOTAL)
The advanced total and grand total menu contain the count (COUNT) and reset (RESET) menus. The count menu
allows the digit limit to be selected between 8-digit (bottom display only) and 13-digit (uses top and bottom display to
display full number) and the initial value at which the total or grand total should start counting.
When using a 13-digit total or grand total, press the function key assigned to display (default: F1) to view the full
amount once the value has exceeded 100,000,000 (decimal places are automatically truncated). If a 13-digit total or
grand total is displayed on the bottom display and the value has exceeded eight digits, the truncated value will flash
to indicate that it is not the complete value. To display 13-digit grand total, assigned the top and bottom display to
grand total.
The reset menu is used to enable or disable the reset of the total and grand total.

Advanced Scaling and Calibration (SCALE.CAL)
This menu offers options to scale or calibrate the meter.
Scaling the Input (SCALE)
The scale menu in the Advanced menu is the same as the scale menu in the Input menu. See Scaling the 4-20 mA
Input (INPUT) on page 36 for details about scaling the meter.
Calibrating the Input (CAL)
To scale the meter without a signal source, refer to
Scaling the 4-20 mA Input (INPUT) on page 36
The meter can be calibrated to display the process in engineering units by applying the appropriate input signal
and following the calibration procedure. The CAL menu should be used with a live signal coming from a 4-20 mA
transmitter connected to the process being measured.
During calibration, the mA input value will be displayed as INP 1 and INP 2. Adjust the input source until the
desired mA value is shown. The use of a calibrated signal source is strongly recommended.
Follow these steps to calibrate the input:
1. After accessing the SCALE.CAL menu, press the Right-Arrow button to scroll to the Calibration menu (CAL RATE)
and press Enter.
2. Select the appropriate units for the desired process variable, then press Enter. For information on units,
see Available Engineering Units on page 37.
3. The meter displays INP 1. Apply a known signal and press Enter. The display will flash while accepting
the signal.
4. After the signal is accepted, the meter displays DSP 1. Enter a corresponding display value for the input
signal , and press Enter to accept.
5. The meter displays INP 2. Apply a known signal and press Enter. The display will flash while accepting
the signal.
6. After the signal is accepted, the meter displays DSP 2. Enter a corresponding display value for the input
signal and press Enter to accept.
7. After completing calibration, the SAVE? display will need to be acknowledged using the Enter key before
calibration will take effect.

Low-Flow Cutoff (CUTOFF)
The low-flow cutoff feature 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.
The cutoff value may be programmed from 0.1 to 99999. The meter will display zero below the cutoff value. The
cutoff can be disabled to display negative values.
Noise Filter (FILTER)
The noise filter is available for unusually noisy signals that cause an unstable process variable display. The noise
filter averages the input signal over a certain period. The filter level determines the length of time over which the
signal is averaged. The filter level can be set between 1 and 16 seconds or turned off. The higher the filter level, the
longer the averaging time and so the longer it takes the display to settle to its final value. Setting the filter level to off
disables the filter function.
Noise Filter Bypass (BYPAS)
The noise filter bypass changes the behavior of the meter so that small variations in the signal are filtered out but
large abrupt changes in the input signal are displayed immediately. The bypass value determines the minimum
amount of signal change to be displayed immediately. All signal changes smaller than the bypass value are filtered
or averaged by the meter. The noise filter bypass may be set between 0.0 and 99.9% of full scale.
Enabling Password Protection (PASSWRD)
The Password menu is used for programming security to prevent unauthorized changes to the programmed
parameter settings or undesired resetting of the total or grand total. There are three separate passwords available
that can be set independently of each other: Main, Total, and Grand Total. The Main, Total, and Grand Total
passwords prevent access to the meter Programming Mode. Total and Grand Total passwords prevent resetting of
the total and grand total, respectively.
To set a password, enter the Password menu and program a five-digit password.
For instructions on how to program numeric values see Setting Numeric Values, page 35.

Making Changes to a Password Protected Meter
If the Main password is enabled, the meter will display the message LOCKED when the Menu button is pressed. If
the Total or Grand Total passwords are enabled, the meter will display the message LOCKED when trying to reset or
change the total or grand total. Press the Enter button while the message is being displayed and enter the correct
password to gain access to the menu. After exiting Programming Mode, the meter returns to its password protected
condition.
Disabling Password Protection
To disable the Main, Total, or Grand Total passwords, access the Password menu and clear the desired password
either by pressing and holding the Right Arrow button until all digits reset to zero or manually changing all of the digits
to zero. When the Enter button is pressed, the meter will display UNLOCKED and will no longer require a password to
access Programming Mode, or a password to reset or change the total or grand total, depending on which password
was cleared.
Note: If the meter is password protected and the password has been forgotten, the password may be overridden using the master
password: 50865
Programmable Function Keys User Menu (USER)
The User menu allows the user to assign the front panel function keys F1, F2, and F3, and the digital input (a digital
input located on the input signal connector) to access some of the menus or to activate certain functions immediately
(e.g. reset max & min, hold relay states, etc.). This allows the meter to be greatly customized for use in specialized
applications.

Enabling the Function Key Hint Feature (HINT)
Enabling the function key hint feature will cause a hint
message to be displayed when pressing the F1, F2,
or F3 function keys. This text gives a brief description
of what the button is programmed to do. Pressing that
function key a second time will execute that action.
The hint feature does not affect the digital input (DI)
which is intended for immediate execution.
Changing System Settings (SYSTEM)
The System menu contains the following menus:
Analog Output Calibration, Restore Factory Defaults,
Totalizer, Backlight, Information, and Internal
Calibration.
Analog Output Calibration (AOUTCAL)
To perform the analog output calibration, it is
recommended to use a milliamp meter with a
resolution of at least 0.1 µA to measure the output
current. The values saved internally during this
procedure are used for scaling the 4-20 mA output in
the Setup menu.
4-20 mA Output Calibration Procedure
1. Go to the Advanced Features menu and
navigate to the SYSTEM menu and press
Enter. Navigate to AOUTCAL and press Enter.
2. The display will show 4 mA. The Loop Leader+
mA output should now be close to 4 mA. Enter
the actual value read by the digital mA meter
on the second line of the display and press
Enter.
3. The display will show 20 mA. The Loop
Leader+ mA output should now be close to 20
mA. Enter the actual value read by the digital
mA meter on the second line of the display
and press Enter.
4. The Loop Leader+ will now calculate the
calibration factors and store them.
5. Press Menu to exit.
Disabling the Totalizer (TOTAL)
The totalizer can be disabled using the SYSTEM TOTAL menu. With the totalizer disabled, the meter
will behave as a PD4-6604 process meter. Refer to
the PD4-6604 instruction manual for instructions
about programming a PD4-6604 process meter.
Enabling or Disabling the Backlight (BACKLITE)
The backlight may be enabled or disabled using the
Backlight menu. The backlight is enabled by default,
but the input must be wired appropriately for the backlight to function. The backlight must be powered by an
external power source. See Wiring Diagrams on page
25. The voltage drop is the same if the backlight is not
wired or if it is disabled in the System menu.
Viewing System Information (INFO)
System information, such as software (firmware)
number and version, model number, and system tag,
may be viewed in the INFO menu. Press the Right
Arrow button to cycle through all available meter
information. Press Menu to go back to the previous
menu.

Calibrating the Internal mA Reference (ICAL)
The meter is factory calibrated prior to shipment to
display 0 to 100, which corresponds to the 4-20 mA
input. The calibration equipment is traceable to
NIST standards.
The use of calibrated signal sources is necessary to
calibrate the internal source of the meter. The meter’s
internal source is what allows the user to scale the
meter without applying a signal.
Check calibration of the meter at least every 12
months.
Note: Allow the meter to warm up for at least 15 minutes
before performing the internal source calibration procedure.
The Internal Calibration menu is part of the Advanced
menu. Internal Calibration is performed as follows:
1. Press the Menu button to enter
Programming Mode.
2. Press the Up-Arrow button twice and press
Enter to access the Advanced menu.
3. Press the Up-Arrow button and press Enter
to access the System menu.
4. Press the Up-Arrow button and press Enter
to access the ICAL menu.
5. The meter displays low input current
message (4.000 mA). Apply a 4 mA signal
and press Enter. The display flashes for a
moment while the meter is accepting the low
input signal.
6. After the display stops flashing, the display
moves to the high input calibration (20.000 mA).
Apply the high input signal and press Enter. The
display will flash again while the meter is
accepting the high input signal.

Meter Operation
The meter is equipped with four buttons behind the
lower panel door used for operation of the meter.
Three buttons labeled F1, F2, and F3 can be
programmed as function keys to perform a variety of
meter functions with a simple push of a button. These
include resetting the total, resetting the meter’s relays
or open collectors, starting and stopping timers,
displaying max/min values and starting/stopping
batches. See Function Keys & Digital Input Available
Settings on page 64 for a complete list of settings
available.
A digital input is available on the meter and it may
function in a similar fashion as the function keys to
allow remote operation of a single task.
The max & min readings (peak & valley) reached by
the process can be displayed either continuously by
assigning it to a display line in the Display menu, or
momentarily by pressing the F1 key (default) or
assign it to any of the other function key or the digital
input.
Pressing the F1 key cycles through various display
values (e.g. Grand total, max, min); press the Enter
key to lock the display in the current process value
and press the Enter key again to unlock the display.
The relay information menu shows runtime and cycle
count for each relay.
Change the display units within the selected unit class
at any time without the need to re-scale the meter.

Total Reset Capabilities
The total and grand total can be reset using a button
behind the lower panel door (F2 default), the remote
contacts connected to a control station, an external
contact closure on the digital input, or MeterView XL.
In addition, both total and grand total reset can be
password protected to prevent unauthorized resets.
Total Reset via Button Under Lower Panel Door
The PD4-6624 is equipped with four buttons located
under the lower panel door. The F2 function key is set
up to reset the total. If reset grand total is enabled, it
is possible for the user to reset either the total or the
grand total.
Total Reset via Remote Contact
The PD4-6624 is equipped with remote contacts
located behind the lower panel door of the meter.
These can be connected to a PDA2364-MRUE
control station for remote operation of all four
programming / operation buttons. The F2 function key
is set by default to reset the total and grand total.
Total Reset via Digital Input
The PD4-6624’s digital input may also be used to reset
the total or grand total.
Total Reset Password Protection
Total and grand total passwords may be set to
prevent resetting the total or grand total unless a
password is entered. Grand total reset may be
disabled through the meter interface, and it may also
be permanently disabled. See Enabling Password
Protection (PASSWRD) on page 62 for details.
Runtime & Cycle Count (INFO)
The relay information menu shows runtime and cycle
count for each relay. These values may be cleared at
any time by selecting the Clear option (CLEAR?). If
the cycle count or runtime values need to be changed
on a frequent basis, it would be convenient to set up a
front panel button or the digital input to simplify this
process.
Note: See the menu tree under Solid-State Relay Outputs
(RELAY) on page 47 for complete menu structure on this
feature.

Batch Controller Operation
Selecting batch control for relay 1 enables the
batching features on the meter. The top display is
changed to show the total and the bottom display is
changed to display the preset batch amount. The
function keys are changed so that F1 starts a batch,
F2 opens the preset menu to allow the preset value to
be changed, and F3 stops the currently running batch.
Enabling batch control for relay 1 allows access to the
batch menu under relay 2 (this menu does not appear
by default).
Refer to page 70 for details to setup the batch
controller features.
The PD4-6624 has two open collector outputs that
can used for alarm indication. A 4-20 mA output
option is also available for retransmitting the process
variable.
Default Batch Control Operation
The following describes the operation of the three
operating keys (located behind the lower panel door
of the PD4-6624) as programmed with default
settings. A more convenient way to achieve batch
control operation with the PD4 is to use a control
station such as the PDA2364-MSBS. See examples
for Manual Batch Control on page 71 and Automatic
Batch Control on page 72.
START Button
Press the START button to begin a new batch
process. Press the START button to resume a batch
that has been stopped.
BATCH Button
Press the Batch button to access the Preset (batch
amount) menu. Program the batch with the arrow
keys, and confirm with the Enter key.
STOP Button
Press the STOP key once during a batch to pause.
Press the STOP key while paused to stop and cancel
the batch.
• Only the STOP Key is Enabled if a Batch is
Running. During a batch process, only the
pause/stop functions are operational, other
buttons are deactivated.
Batch Control Operation Example
The following example shows how two stage batch
control functions with a Loop Leader+. This setup will
establish a 55-gallon preset for the batch, with a main
valve (high flow) that will close at 50 gallons, and a
trickle valve (low or restricted flow) that will close at
55 gallons. Because the first batch overruns by 0.10,
the batch preset will be changed to 54.90 for the next
batch to compensate for overrun.

Manual Batch Control
The manual batch control feature is used for batch processes that the operator wants to start manually. It can also be
used where the batch size needs to be manually adjusted for each batch. The batch can be controlled using a
PDA2364-MSBS control station connected to the remote contacts.
System Setup
Both valves are closed with an
empty barrel in place. The batched
total is displayed in the upper
display, the preset is selected for
the lower display.
Batch Start
The START button or (F1) is
pressed. Both valves open. The
barrel begins to fill.
Preclose Valve
When the batch total reaches a
value of 50.00 (Preset [55.00] –
Pre-close [5.00]) the full-flow valve
closes. The fill rate of the tank slows
as a result.
Completed Batch
When the batch is complete, the
restricted-flow valve closes. If
overrun occurs, then the preset
must be adjusted to compensate for
the overrun. The next batch will only
start after the START button or (F1)
is pressed.
Overrun Correction
To compensate for overrun in the
previous batch, adjust the preset to
54.90, so that the next batch is
accurate (55.00).
Manual Start of Next Batch
A new, empty, barrel is put in place
and the START button or (F1) is
pushed to manually start the next
batch.
Change Batch Size
While the process is stopped, a new
preset fill amount may be selected
with the Batch key (F2) for a
different size barrel.
Pause/Stop
At any time, press the STOP button
or Stop key (F3) once to pause the
process, or twice to cancel the
batch, which stops the process.
Resume Batch
If the batch has been paused, then
press START button or (F1) to
resume the batch process.

Automatic Batch Control
The automatic batch control feature is used for batches that start automatically once the previous batch is completed.
There is no opportunity for the operator to change the batch size between batches. The batch can be controlled using
a PDA2364-MSBS control station connected to the remote contacts.
System Setup
Both valves are closed with an
empty barrel in place. The batched
total is displayed in the upper
display, the preset is selected for
the lower display.
Batch Start
The START button or (F1) is
pressed. Both valves open. The
barrel begins to fill.
Preclose Valve
When the batch total reaches a
value of 50.00 (Preset [55.00] –
Pre-close [5.00]) the full-flow valve
closes. The fill rate of the tank slows
as a result.
Completed Batch
When the batch is complete, the
restricted-flow valve closes. If
overrun occurs, then the preset
must be adjusted to compensate for
the overrun.
Start Delay
After the batch is completed, the
operator removes the full barrel and
places an empty barrel; the new
batch starts automatically after 60
seconds (Time Delay).
Automatic Start of Next Batch
The next batch begins automatically
after 60 seconds, both relays
activate and both valves open.
Pause
At any time, press the STOP button
or Stop key (F3) once to pause the
process.
Resume Batch
If the batch has been paused, then
press START button or (F1) to
resume the batch process.
Stop Process
At the end of the shift, press STOP
button or Stop key (F3) twice to stop
the batch process.

Troubleshooting Tips
Certain sequences of events can cause unexpected results. To solve these issues, it is best to start fresh from factory
defaults and use the manual as a step by step programming guide, rather than a random approach to programming.
See Reset Meter to Factory Defaults on page 73 for details on resetting the meter to factory defaults. In addition, for
best results, we recommend using the free MeterView XL software for all programming needs.
