GENERAL DESCRIPTION

The Large Display is a versatile display that can be congured as a single or

dual counter with rate indication, scaling, serial communications and a dual

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/IP65 enclosure in light weight aluminum.

The 6-digit programmable models have two signal inputs and a choice of

eight dierent 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 dual Form C relay output and

RS232 or RS485 serial communications. The outputs can activate based on

either counter or rate setpoint values. An internal batch counter can be used to

count setpoint output activations.

SRC.: Adds internal 3.9 K pull-down resistor, 7.2 mA max. @ 28 VDC max.

SWITCH 7 (POWER UP RESET)

ENABLE: In this position, the counter resets to zero at power up.

DISABLE: In this position, the counter does not reset at power up.

Note: This switch has no function for programmable models. Power-up reset is

selected through a programming parameter.

SWITCH 8 (Input B)

DIRECTION CONTROL: In this position Input B is used to control the

count direction of Input A when Input A is set to Count with Direction

mode (default mode).

INTENSITY ADJUST: In this position Input B is used to adjust the

LED intensity. There are ve distinct LED levels that can be changed by

pulsing Input B. After setting the desired intensity, move switch to

OFF position for Direction Control. Units with keypads can program the

LED intensity level using Programming Menu 3.

Note 1: When the DIP switch is in the SNK position (OFF), the input is

congured as active low. When the switch is in the SRC position (ON), the

input is congured as active high.

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 dierent 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 dierence 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 eectiveness.

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 eective. 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:

Schaner # FN610-1/07 (RLC# LFIL0000)

Schaner # FN670-1.8/07

Corcom # 1 VR3

Note: Reference manufacturer's instructions when installing a line lter.

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.
