GENERAL DESCRIPTION

The PAX® Lite Process Time Meter, Model PAXLPT, displays a value
representing the time between a beginning and end point of a process, such as a
conveyor oven.

The PAXLPT’s display will update inversely in relation to the input signal
frequency. As input frequency increases (representing speed), the PAXLPT
time display will decrease indicating a reduction in the duration of process
time. For example, the bake time through an oven will decrease the faster the
conveyor runs.

The display can be programmed for two operating modes. Operating in the 6
digit mode, the PAXLPT can readout in any whole value, such as seconds,
minutes, or hours. This mode also provides capability for decimal points. The 5
digit mode functions as a chronometer, which has a maximum display value of
999-59. This formats the display to allow the meter to readout in hours and
minutes, minutes and seconds, etc.

The PAX Lite Process Time Indicator also has a feature called “moving
window average”. This allows one time disturbances, or irregularly spaced
items to be averaged over eight inputs, thus keeping display fluctuations to a
minimum while still updating the display on every pulse. This feature can be
enabled or disabled by a rear DIP switch.

The PAXLPT can accept many different types of sensors including magnetic
pickups, logic sensors, and NPN open collector sensors, as well as switch
contact closure sensors.

The meter has been specifically designed for harsh industrial environments.
With a NEMA 4X/IP65 sealed bezel and extensive testing to meet CE
requirements, the meter provides a tough yet reliable application solution.

DIMENSIONS In inches (mm)

Note: Recommended minimum clearance (behind the panel) for mounting clip installation is

2.1" (53.4) H x 5" (127) W.

1.0 INSTALLING THE METER

Installation

The PAX Lite meets NEMA 4X/IP65 requirements when properly installed.
The unit is intended to be mounted into an enclosed panel. Prepare the panel
cutout to the dimensions shown. Remove the panel latch from the unit. Slide the
panel gasket over the rear of the unit to the back of the bezel. The unit should
be installed fully assembled. Insert the unit into the panel cutout.

While holding the unit in place, push

the panel latch over the rear of the

unit so that the tabs of the panel

latch engage in the slots on

the case. The panel latch

should be engaged

in the farthest

forward slot possible. To achieve a proper seal, tighten the latch screws evenly
until the unit is snug in the panel (Torque to approximately 7 in-lbs [79N-cm]).
Do not over-tighten the screws.

Installation Environment

Inside the meter is also the Mode Selection Jumper, located near the display
board. This jumper will select operation in the 6 digit mode or 5 digit
(chronometer) mode. When the jumper is positioned toward the display board,
the unit will be in the 6 digit mode of operation. With the jumper positioned
away from the display board, the meter is in the 5 digit (chronometer) mode.
This unit ships from the factory in the 6 digit mode.

Set-Up DIP Switches

A DIP switch is located at the rear of the meter,
and is fully accessible when the unit is in the case.
It is used for the selection of the input parameters

3.0 WIRING THE METER

WIRING OVERVIEW

Electrical connections are made via screw-clamp terminals located on the
back of 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 embossed on the back of the
meter case against those shown in wiring drawings for proper wire position. Strip
the wire, leaving approximately 0.3" (7.5 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.)

EMC INSTALLATION GUIDELINES

Although this meter is designed with a high degree of immunity to Electro­Magnetic 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 mounted in a metal enclosure, which is 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.

REAR TERMINALS

INPUT SET-UP
DIP SWITCHES

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 run 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.

5.0 SCALING THE METER

In many industrial applications, a meter is required to display the process
time of an operation or event. The pulses from a sensor are received by the
P AXLPT, and then scaled to produce just such a readout. The following formula
will help provide the scaling values to achieve the desired readout.

SF = DR x PPS

WHERE:

SF = Scale Factor
DR = Desired Readout*
PPS = Pulses per Second

To calculate the PPS multiply the RPM (Revolutions per Minute) by the PPR
(Pulses per Revolution) and divide by 60.

RPM x PPR
60

*For applications requiring a decimal point, select and program the
appropriate decimal point. When calculating the Scale Factor, use the whole
value of the number to be displayed, for example, 50.0 minutes, the Desired
Readout in this case is 500. Do not use decimal points in the Desired Readout
when calculating the scale factor.

For calculated SF values less than 59,999

If the Scale Factor is a value less than 59,999, it can be entered directly

into the meter as the Scale Factor and the Scale Multiplier can be left at 1.

For calculated SF values greater than 59,999

If the Scale Factor is a value over 59,999 (maximum value), the Scale
Multiplier must be used to reduce the calculated Scale Factor value until it is
less than 59,999. The Scale Multiplier divides the calculated Scale Factor
value by 1, 10, 100 and 1000, thus reducing the calculated value accordingly.
Select the appropriate Scale Multiplier value that allows the Scale Factor to
be a value under 59,999. Both the Scale Factor and Scale Multiplier can then
be entered into the meter.

Example 1 (6 Digit):

DR = 150 minutes
PPS = 450 RPM x 60 PPR

60
PPS = 450

SF = DR x PPS

SF = 150 x 450
SF = 67,500

Since the SF value is greater than 59,999, the SM will be needed to reduce
the calculated value to value less than 59,999. Using the SM of 10, the 67,500
value is divide by 10, reducing the SF to a value of 6750. The meter can be
programmed for a SF of 6750 and a SM of 10.

Example 2 (5 Digit):

DR = 2 hours and 23 minutes (2-23)

PPS = 138 RPM x 100 PPR

60

PPS = 230

To calculate the Scale Factor for a 5 Digit application, first convert the DR
to its base units.

DR = 2 (hours) x 60 + 23

DR = 120 + 23

DR = 143 minutes

SF = DR x PPS

SF = 143 x 230

SF = 32,890

Since the SF value is less than 59,999, it can be entered directly as the SF
and the SM will be 1. Note: When programmed for the 5 Digit mode, the

meter will convert the D.R. back to the hours and minutes format.
