DESCRIPTION

The Model IFMA accepts a frequency input, and outputs an analog voltage or
current in proportion to the input frequency, with 0.1% accuracy. The full scale
input frequency can be set to any value from 1 Hz to 25 KHz, either with a
frequency source, or digitally with the on-board rotary switch and push-button.

The IFMA utilizes a seven position DIP switch, a rotary switch, a push-button
and two indication LEDs to accomplish input circuit configuration, operational
parameter set-up, and Input/Output indication. The input circuitry is DIP switch
selectable for a variety of sources.

The indication LEDs are used during normal operation to display the input
and output status of the IFMA. These LEDs are also used to provide visual
feedback to the user of the existing parameter settings during parameter set-up.

The IFMA operates in one of four output modes. The programmable minimum
and maximum response times provide optimal response at any input frequency.

The unit is equipped with a universal mounting foot for attachment to
standard DIN style mounting rails, including top hat profile rail according to EN
50 022 - 35 x7.5 and 35 x 15, and G profile rail according to EN 50 035 - G 32.

OVERVIEW

The Model IFMA continuously monitors a frequency input and outputs a
voltage or current signal in proportion to the input signal. The output is accurate
to ±0.1% of full scale for Operating Modes 2, 3, and 4. Operating Mode 1 is
accurate to ±0.2% of full scale. The green Input LED blinks at the rate of the
input frequency. At about 100 Hz, the Input LED will appear to be solid on. At
very low frequencies, the Input LED blinks slowly and may also appear to be
solid on. A loss of signal may also cause the Input LED to remain on, depending
on the DIP switch set-up. In this case, the red LED also turns on.

The Minimum Response Time parameter sets the minimum update time of the
output. The actual response time is the Minimum Response Time plus up to one
full period of the input signal. The IFMA counts the negative edges occurring
during the update time period, and computes the average frequency value for that
time. This action filters out any high frequency jitter that may be present in the
input signal. The longer the Minimum Response Time, the more filtering occurs.

The Maximum Response Time parameter sets the Low Frequency Cut-out
response time for the unit. If a new edge is not detected within the time specified
by the Maximum Response Time setting, the unit sets the output to the
existing Low Frequency Cut-out Value setting depending on the selected range
and calibration setting.

The unit also indicates Low Frequency Cut-out by turning ON the output
LED. The Maximum Response Time can be set shorter than the Minimum
Response Time. In this case, as long as the input signal period is shorter than the
Maximum Response Time, the unit continues to indicate the input frequency at
its output. But, if the input period at any time exceeds the Maximum Response
Time, the unit immediately takes the output to the Low Frequency Cut-out
Value, regardless of the Minimum Response Time setting.

The IFMA is calibrated at the factory for all of the selected ranges. However,
the user can adjust the minimum calibration to any value less than the Full Scale
value, and the Full Scale value to any value greater than the minimum value. If
the minimum and full scale values are brought closer together, the accuracy of the
unit decreases proportionate to the decreased range of the unit (See Calibration).

EMC INSTALLATION GUIDELINES

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

Although this unit 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 unit may be different for
various installations. The unit 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 installation or troublesome
installation.

Listed below are some EMC guidelines for successful installation in an
industrial environment.

1. 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 rail 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 unit and leave the other end of the

shield unconnected and insulated from earth ground.

2. 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.

3. Signal or Control cables within an enclosure should be routed as far away as

possible from contactors, control relays, transformers, and other noisy

components.

4. 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 #1VR3

Note: Reference manufacturer’s instructions when installing a line filter.

5. Long cable runs are more susceptible to EMI pickup than short cable runs.

Therefore, keep cable runs as short as possible.

POWER AND OUTPUT CONNECTIONS

AC Power

Primary AC power is connected to terminals 10 and 12 (labeled AC). For best
results, the AC Power should be relatively “clean” and within the specified
variation limits. Drawing power from heavily loaded circuits or from circuits
that also power loads that cycle on and off, should be avoided.

DC Power

The DC power is connected to terminals 10 and 12. The DC plus (+) power
is connected to terminal 10 and the minus (-) is connected to terminal 12.

It is recommended that separate supplies be used for sensor power and unit
power. Using the same supply for both will negate isolation between input and
power.

Current Output

When using Operating Mode 3 or 4, the output device is connected to
terminals 1(I+) and 3 (I-).

Voltage Output

When using Operating Mode 1 or 2, the output device is connected to
terminals 4 (V+) and 6 (V-).

Note: Although signals are present at

voltage and current outputs at the

same time, only the selected mode is

in calibration at any one time.

Example: Operating Mode 2 is

selected. The voltage level present
at the voltage terminals is in
calibration, but the signal
appearing at the current terminals
does not conform to either of the
current output modes.

WIRING CONNECTIONS

All conductors should meet voltage and current ratings for each terminal.
Also cabling should conform to appropriate standards of good installation, local
