GENERAL DESCRIPTION

The FLEX MINI Series provides the user the ultimate in flexibility, from its
complete user programming to the optional setpoint control and communication
capability. The FLEX MINI accepts a DC voltage or current input signal and
provides a display in the desired unit of measure. The meter also features
minimum and maximum display capture, display offset, units indicator, and
programmable user input. The display can be toggled either manually or
automatically between the selected displays.

The FLEX MINI display has 0.48" (12.2 mm) high digits. The LCD is
available in two versions, reflective or red/green backlight. The backlight
version is user selectable for the desired color and also has variable display
intensity.

The capability of the FLEX MINI can be easily expanded with the addition
of option cards. The setpoint output cards are field installable with programmable
setpoints. Serial communications capability for RS232 or RS485 can be added
with a serial option card.

The FLEX MINI can be powered from an optional Veeder Root Micro-Line/
Sensor Power Supply (MLPS), which attaches directly to the back of a FLEX
MINI. The MLPS is powered from 85 to 250 VAC and provides up to 400 mA
to drive the unit and sensors.

INPUT

The FLEX MINI is a DC Process meter. It features voltage and current input
ranges, that are selected by the user via a programming jumper and software
input range selection. The ranges consist of the following: 0 to 10 V, 0(4) to 20
mA, or 0 to 50 mA. Users should select the appropriate voltage range that

2.0 SettinG the JuMperS

INPUT RANGE JUMPER

This jumper is used to select the proper input range. The input range selected
in programming must match the jumper setting. Select a range that is high
enough to accommodate the maximum input signal to avoid overloads. To
access the jumper, remove the rear cover of the meter.

Warning: Exposed line voltage exists on the circuit boards.
Remove all power to the meter and load circuits before accessing
inside of the meter.

REMOVING THE REAR COVER

To remove the rear cover, locate the cover locking tab below the 2nd and 3rd
input terminals. To release the tab, insert a small, flat blade screwdriver between
the tab and the plastic wall below the terminals. Inserting the screwdriver will
provide enough pressure to release the tab locks. To replace the cover, align the
cover with the input terminals and press down until the cover snaps into place.

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.

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.) 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).

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.

CAUTION: The Plug-in cards and main circuit board contain static

sensitive components. Before handling the cards, discharge
static charges from your body by touching a grounded bare
metal object. Ideally, handle the cards at a static controlled
clean workstation. Also, only handle the cards by the edges.
Dirt, oil or other contaminants that may contact the cards can
adversely affect circuit operation.

REMOVING THE REAR COVER

To remove the rear cover, locate the cover locking tab below the 2nd and 3rd
input terminals. To release the tab, insert a small, flat blade screwdriver between
the tab and the plastic wall below the terminals. Inserting the screwdriver will
provide enough pressure to release the tab locks. To replace the cover, align the
cover with the input terminals and press down until the cover snaps into place.

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
TDK # ZCAT3035-1330A
Steward # 28B2029-0A0

Line Filters for input power cables:

Schaffner # FN2010-1/07
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.

PROGRAMMING MODE ENTRY (SEL BUTTON)

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 and holding the SEL button. If it is not accessible then it is locked by
either a security code, or a hardware lock.

MODULE ENTRY (SEL & RST BUTTONS)

The Programming Menu is organized into separate modules. These modules
group together parameters that are related in function. The display will alternate
between Pro and the present module. The RST button is used to select the desired
module. The displayed module is entered by pressing the SEL button.

MODULE MENU (SEL BUTTON)

Each module has a separate module menu (which is shown at the start of each
module discussion). The SEL button 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 RST button is used to move through
the selections/values for that parameter. Pressing the SEL button, stores and
activates the displayed selection/value. This also advances the meter to the next
parameter.

For numeric values, press the RST button to access the value. The right hand
most digit will begin to flash. Pressing the RST button again increments the
digit by one or the user can hold the RST button and the digit will automatically
scroll. The SEL button will advance to the next digit. Pressing and holding the

SEL button will enter the value and move to the next parameter.

the Display Mode, verify recent parameter changes.)

PROGRAMMING TIPS

It is recommended to start with Module 1 and proceed through each module in
sequence. 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 2. This is useful
when encountering programming problems.

ALTERNATING SELECTION DISPLAY

In the explanation of the modules, the following dual display with arrows will

The display can be corrected with an offset value. This can be used to
compensate for signal variations or sensor errors. This value is automatically
updated after a Zero Display to show how far the display is offset. A value of
zero will remove the effects of offset.

FILtr



If the displayed value is difficult to read due to small process variations or
noise, increased levels of filtering will help to stabilize the display. Software
filtering effectively combines a fraction of the current input reading with a
fraction of the previous displayed reading to generate the new display.

Filter values represent no filtering (0), up to heavy filtering (3). A value of 1
for the filter uses 1/4 of the new input and 3/4 of the previous display to generate
the new display. A filter value of 2 uses 1/8 new and 7/8 previous. A filter value
of 3 uses 1/16 new and 15/16 previous.

FILTER BAND



The filter will adapt to variations in the input signal. When the variation
exceeds the input filter band value, the filter disengages. When the variation
becomes less than the band value, the filter engages again. This allows for a
stable readout, but permits the display to settle rapidly after a large process
change. The value of the band is in display units, independent of the Display
Decimal Point position. A band setting of ‘0’ keeps the filter permanently
engaged at the filter level selected above.

General Notes on Scaling

1. When using the Apply (APLY) scaling style, input values for scaling points

must be confined to signal limits of the selected range.

2. The same Input Value should not correspond to more than one Display Value.
(Example: 10 V can not equal 0 and 10.)

3. For input levels beyond the programmed Input Values, the meter extends the
Display Value by calculating the slope from the two coordinate pairs (INP1 /

dSP1 & INP2 / dSP2).

For most applications, recalibration every 1 to 2 years should be sufficient.

Calibration of the RFMP involves a voltage or current calibration, which
should only be performed by individuals experienced in calibrating electronic
equipment. Allow a 30 minute warm up for eqiupment and unit before
performing any calibration related procedures. The following procedures should
be performed at an ambient temperature of 15 to 35°C (59 to 95°F).

CAUTION: The accuracy of the calibration equipment will directly affect the

accuracy of the RFMP.

Calibration

1. Connect the negative lead of a precision DC source with an accuracy of 0.01%

or better to the COMM. Leave the positive lead of the DC source unconnected.

2. With the display at CodE 48, press and hold the SEL button for 2 seconds. Unit

will display CAL NO.

3. Press the RST button to select the range to be calibrated.

4. Press the SEL button. Display reads 0.0A (0.0 V for voltage).

5. Apply 0 signal:

Current: leave the positive lead of the DC source unconnected.
Voltage: apply a short to the input or connect the positive lead of the DC

Press SEL. Display reads CALC for about 8 seconds.

6. When the display reads the selected range (10 V, 20 mA, or 50 mA), connect

the positive lead of the DC source to INP+ and apply the full scale input signal

for the range. Press SEL. Display reads CALC for about 8 seconds.

7. Repeat steps 3 through 6 for each input range to be calibrated. When display

reads CAL NO, press the SEL button to exit calibration.

CALIBRATION

The RFMP uses stored calibration values to provide
accurate voltage and current measurements. Over time,
the electrical characteristics of the components inside the
meter could slowly change, therefore the stored calibration
values may no longer accurately define the input circuit.

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 (P-Loc) 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 values 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 CodE prompt in order to access Full Programming mode. Depending on the
code value, Quick Programming may be accessible before the CodE prompt
appears (see chart).
