GENERAL DESCRIPTION
The Large Display is a versatile display that can be configured as a single or
dual counter with rate indication, scaling, serial communications and a relay
output. There are also basic models that have a single counter with direction
control only (no scaling or relay output).
The 4 & 6 digit displays are available in either 2.25" or 4" high red LED digits
with adjustable display intensities. The 2.25" high models are readable up to 130
feet. The 4" high models are readable up to 180 feet. All versions are constructed
of a NEMA 4X enclosure in light weight aluminum.
The 6-digit programmable models have two signal inputs and a choice of
eight different count modes. These include bi-directional, quadrature and anti-
coincidence counting, as well as a dual counter mode. When programmed as a
dual counter, each counter has separate scaling and decimal point selection.
Rate indication is available on the programmable models only. The rate
indicator has separate scaling and decimal point selection, along with
programmable display update times. The meter display can be toggled either
manually or automatically between the count and rate values.
The programmable models also come with a Form C relay output and jumper
selectable RS232 or RS485 serial communications.

EMC INSTALLATION GUIDELINES
Although this meter is designed with a high degree of immunity to Electro-
Magnetic Interference (EMI), proper installation and wiring methods must be
followed to ensure compatibility in each application. The type of the electrical
noise, source or coupling method into the meter may be different for various
installations. The meter becomes more immune to EMI with fewer I/O
connections. Cable length, routing, and shield termination are very important
and can mean the difference between a successful or troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.
1. The meter should be properly connected to protective earth.
2. Use shielded (screened) cables for all Signal and Control inputs. The shield
(screen) pigtail connection should be made as short as possible. The
connection point for the shield depends somewhat upon the application.
Listed below are the recommended methods of connecting the shield, in order
of their effectiveness.
a. Connect the shield only at the panel where the unit is mounted to earth
ground (protective earth).
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is above 1 MHz.
c. Connect the shield to common of the meter and leave the other end of the
shield unconnected and insulated from earth ground.
3. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be ran in metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter.
4. Signal or Control cables within an enclosure should be routed as far as possible
from contactors, control relays, transformers, and other noisy components.
5. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Signal
and Control cables as close to the unit as possible. Loop the cable through the
core several times or use multiple cores on each cable for additional protection.
Install line filters on the power input cable to the unit to suppress power line
interference. Install them near the power entry point of the enclosure. The
following EMI suppression devices (or equivalent) are recommended:
Ferrite Suppression Cores for signal and control cables:
Fair-Rite # 0443167251 (RLC# FCOR0000)
TDK # ZCAT3035-1330A
Steward # 28B2029-0A0
Line Filters for input power cables:
Schaffner # FN610-1/07 (RLC# LFIL0000)
Schaffner # FN670-1.8/07
Corcom # 1 VR3
Note: Reference manufacturer's instructions when installing a line filter.
6. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.
7. Switching of inductive loads produces high EMI. Use of snubbers across
inductive loads suppresses EMI.
Snubber: RLC# SNUB0000.

Terminal 1: NC
Terminal 2: NO
Terminal 3: Relay Common
WIRING OVERVIEW
Electrical connections are made via pluggable terminal blocks
located inside the meter. All conductors should conform to the
meter's voltage and current ratings. All cabling should conform
to appropriate standards of good installation, local codes and
regulations. It is recommended that the power supplied to the
meter (DC or AC) be protected by a fuse or circuit breaker. When
wiring the meter, compare the numbers on the label on the back
of the meter case against those shown in wiring drawings for
proper wire position. Strip the wire, leaving approximately 0.4"
(10 mm) bare lead exposed (stranded wires should be tinned with
solder.) Insert the lead under the correct screw clamp terminal
and tighten until the wire is secure. (Pull wire to verify tightness.)
Each terminal can accept up to one #14 AWG (2.55 mm) wire,
two #18 AWG (1.02 mm), or four #20 AWG (0.61 mm).

3.4 INPUT WIRING
The Large Display has two signal inputs, A and B. These inputs are wired to
terminal block TBB located inside the unit on the right side.
Terminal 1: Input A
Terminal 2: Input B
Terminal 4: Input Common
Programmable models LD2006P0 and LD4006P0 provide a choice of eight
different Count Modes. The Count Mode selected determines the action of
Inputs A and B. Section 5.1, Input Setup Parameters, provides details on count
mode selection and input action.
All other models are non-programmable and provide Count with Direction
Mode only. Input A accepts the count signal, while Input B controls the count
direction (up/down).
Input B can also be used to adjust the LED display intensity by setting DIP
Switch 8 to the ON position (See Section 2.0, Setting the DIP Switches). For
programmable models, this only applies in Count with Direction mode.
CAUTION: DC common is NOT isolated from input common. In order to preserve the safety of the meter application, the DC common must be suitably
isolated from hazardous live earth referenced voltage; or input common must be at protective earth ground potential. If not, hazardous voltage may
be present at the User Input and Input Common terminals. Appropriate considerations must then be given to the potential of the input common with
respect to earth ground.

Equipment (DCE) receives data on the TXD line and transmits data on the RXD
line. The PAX emulates a DTE. If the other device connected to the meter also
emulates a DTE, the TXD and RXD lines must be interchanged for
communications to take place. This is known as a null modem connection. Most
printers emulate a DCE device while most computers emulate a DTE device.
Some devices cannot accept more than two or three characters in succession
without a pause in between. In these cases, the meter employs a busy function.
As the meter begins to transmit data, the RXD line (RS232) is monitored to
determine if the receiving device is “busy”. The receiving device asserts that it
is busy by setting the RXD line to a space condition (logic 0). The meter then
suspends transmission until the RXD line is released by the receiving device.
RS485 Communications
The RS485 communication standard allows the connection of up to 32
devices on a single pair of wires, distances up to 4,000 ft. and data rates as high
as 10M baud (the PAX is limited to 19.2k baud). The same pair of wires is used
to both transmit and receive data. RS485 is therefore always half-duplex, that is,
data cannot be received and transmitted simultaneously.
RS232 Communications
RS232 is intended to allow two devices to communicate over distances up to
50 feet. Data Terminal Equipment (DTE) transmits data on the Transmitted Data
(TXD) line and receives data on the Received Data (RXD) line. Data Computer

PROGRAMMING MODE ENTRY (PAR KEY)
It is recommended all programming changes be made off line, or before
installation. The meter normally operates in the Display Mode. No parameters
can be programmed in this mode. The Programming Mode is entered by
pressing the PAR key. If it is not accessible, then it is locked by either a security
code or a hardware lock.
MODULE ENTRY (SELS& PAR KEYS)
The Programming Menu is organized into five modules. These modules group
together parameters that are related in function. The display will alternate between
Pro and the present module. The SELSSkey is used to select the desired module.
The displayed module is entered by pressing the PAR key.
MODULE MENU (PAR KEY)
Each module has a separate module menu (which is shown at the start of each
module discussion). The PAR key is pressed to advance to a particular parameter
to be changed, without changing the programming of preceding parameters.
After completing a module, the display will return to Pro NO. Programming
may continue by accessing additional modules.
SELECTION / VALUE ENTRY
For each parameter, the display alternates between the present parameter and
the selections/value for that parameter. The SELSSand RSTTTkeys are used to
move through the selections/values for that parameter. Pressing the PAR key,
stores and activates the displayed selection/value. This also advances the meter to
the next parameter.
For numeric values, the value is displayed with one digit flashing (initially the
left most digit). Pressing the SELSSkey increments the digit by one or the user
can hold the SELSSkey and the digit will automatically scroll. The RSTTTkey
will select the next digit to the right. Pressing the PAR key will enter the value
and move to the next parameter.
PROGRAMMING MODE EXIT (PAR KEY)
The Programming Mode is exited by pressing the PAR key with Pro NO
displayed. This will commit any stored parameter changes to memory and return
the meter to the Display Mode. (If power loss occurs before returning to the
Display Mode, verify recent parameter changes.)
PROGRAMMING TIPS
It is recommended to start with Module 1 for counting or Module 2 for rate.
When programming is complete, it is recommended to record the parameter
programming and lock out parameter programming with the user input or
programming security code.
FACTORY SETTINGS
Factory Settings may be completely restored in Module 3. This is useful when
encountering programming problems.
Pressing the RSTTTkey on power-up will load the factory settings and display
. This allows operation in the event of a memory failure or corrupted data.
ALTERNATING SELECTION DISPLAY
In the explanation of the modules, the following dual display with arrows will
appear. This is used to illustrate the display alternating between the parameter
on top and the parameter’s Factory Setting on the bottom. In most cases,
selections and values for the parameter will be listed on the right.

SCALING FOR COUNT INDICATION
The counter’s scale factor is factory set to 1, to provide one count on the
display for each pulse that is input to the unit. In many applications, there will
not be a one-to-one correspondence between input pulses and display units.
Therefore, it is necessary for the meter to scale or multiply the input pulses by
a scale factor to achieve the desired display units (feet, meters, gallons, etc.)
The Count Scale Factor Value can range from 00.0001 to 99.9999. It is
important to note that the precision of a counter application cannot be improved
by using a scale factor greater than one. To accomplish greater precision, more
pulse information must be generated per measuring unit. The following formula
is used to calculate the scale factor.
Scale Factor = Desired Display Unitsx Decimal Point Position
Number of Pulses
WHERE:
Desired Display Units: Count display units acquired after pulses that occurred.
Number of Pulses: Number of pulses required to achieve the desired
display units.
Decimal Point Position:
0=1
0.0 = 10
0.00 = 100
0.000 = 1000
0.0000 = 10000

EXAMPLE: The counter display is used to indicate the total number of feet
used in a process. It is necessary to know the number of pulses for the desired
units to be displayed. The decimal point is selected to show the resolution in
hundredths.
Scale Factor = Desired Display Unitsx Decimal Point Position
Number of Pulses
Given that 128 pulses are equal to 1 foot, display total feet with a one-
hundredth resolution.
Scale Factor = 1.00 x 100
128
Scale Factor = 0.007812 x 100
Scale Factor = 0.7812

SCALING FOR RATE INDICATION
To scale the Rate, enter a Scaling Display value with a corresponding Scaling
Input value. These values are internally plotted to a Display value of 0 and Input
value of 0 Hz. A linear relationship is formed between these points to yield a rate
display value that corresponds to the incoming input signal rate. The meter is
capable of showing a rate display value for any linear process.
SCALING CALCULATION
If a display value versus input signal (in pulses per second) is known, then
those values can be entered into Scaling Display () and Scaling Input
(). No further calculations are needed.
If only the number of pulses per ‘single’ unit (i.e. # of pulses per foot) is
known, then it can be entered as the Scaling Input value and the Scaling Display
value will be entered as the following:
NOTES:
1. If # of pulse per unit is less than 10, then multiply both Input and Display
values by 10.
The Low Update Time is the minimum amount of time between display
updates for the Rate display. Values of 0.1 and 0.2 seconds will update the
display correctly but may cause the display to appear unsteady.
RATE LOW UPDATE TIME
 to  seconds
The High Update Time is the maximum amount of time before the Rate
display is forced to zero. (For more explanation, refer to Rate Value
Calculation.) The High Update Time must be higher than the Low Update Time
and higher than the desired slowest readable speed (one divided by pulses per
second). The factory setting of 2.0, will force the display to zero for speeds
below 0.5 Hz or a pulse every 2 seconds.

Module 2 is the programming for the Rate parameters. For maximum input
frequency, Rate Enable should be set to  when not in use. When set to , the
remaining rate parameters are not accessible. The Rate value is shown with an
annunciator of “” in the Display Mode.
This selects the decimal point position for rate displays and any setpoint value
assigned to these displays. This parameter does not affect rate scaling calculations.

2. If # of pulse per unit is less than 1, then multiply both Input and Display
values by 100.
3. If the Display value is raised or lowered, then Input value must be raised
or lowered by the same proportion (i.e. Display value for per hour is
entered by a third less (1200) then Input value is a third less of # of pulses
per unit). The same is true if the Input value is raised or lowered, then
Display value must be raised or lowered by the same proportion.
4. Both values must be greater than 0.0.
EXAMPLE:
1. With 15.1 pulses per foot, show feet per minute in tenths. Scaling Display
= 60.0 Scaling Input = 15.1.
2. With 0.25 pulses per gallon, show whole gallons per hour. (To have greater
accuracy, multiply both Input and Display values by 10.) Scaling Display
= 36000 Scaling Input = 2.5.

Minute 60 # of pulses per unit

INPUT FREQUENCY CALCULATION
The meter determines the input frequency by summing the number of falling
edges received during a sample period of time. The sample period begins on the
first falling edge. At this falling edge, the meter starts accumulating time
towards Low Update and High Update values. Also, the meter starts
accumulating the number of falling edges. When the time reaches the Low
Update Time value, the meter looks for one more falling edge to end the sample
period. If a falling edge occurs (before the High Update Time value is reached),
the Rate display will update to the new value and the next sample period will
start on the same edge. If the High Update Time value is reached (without
receiving a falling edge after reaching Low Update Time), then the sample

The Security Code determines the programming mode and the accessibility
of programming parameters. This code can be used along with the Program
Mode Lock-out () in the User Input Function parameter (Module 1).
Two programming modes are available. Full Programming mode allows all
parameters to be viewed and modified. Quick Programming mode permits only
the Setpoint value and Output Time-out value to be modified, but allows direct
access to these values without having to enter Full Programming mode.
Programming a Security Code other than 0, requires this code to be entered
at the  prompt in order to access Full Programming mode. Depending on
the code value, Quick Programming may be accessible before the  prompt
