GENERAL DESCRIPTION
The Model 7558 (Strain Gage Input Meter) offers many features and
performance capabilities to suit a wide range of industrial applications. The 4½
digit meter employs advanced technology for stable, drift free readout, while
incorporating features that provide flexibility now and in the future with Plug-
in option cards. The plug-in card options allow the opportunity to configure the
meter for present applications, while providing easy upgrades for future needs.
The Strain Gage meter has two bipolar mV input ranges:  24 mV DC or 
240 mV DC. The internal bridge excitation is selectable for 5 VDC or 10 VDC.
The excitation output is based on a reference, ensuring accurate and drift-free
readouts. A 16 point scaling feature compensates for square-law devices and
other non-linear process characteristics.
The meter provides a Max and Min reading memory with programmable
capture time. The capture time is used to prevent detection of false max and min
readings which may occur during burst testing or unusual process events.
The signal totalizer (integrator) can be used to compute a time-input product.
This can be used to provide a readout of totalized flow, calculate service
intervals of motors and pumps, etc. The totalizer can also accumulate batch
weighing operations (batch weight).
The meter has four setpoint outputs, implemented on Plug-in cards. The
Plug-in cards provide dual FORM-C relays (5 A), quad FORM-A relays (3 A)
or either sinking or sourcing quad open collector logic outputs. The setpoint
alarms can be configured in modes to suit a variety of control and alarm
requirements.
- High and low absolute, high and low deviation and band acting
- Balanced or unbalanced hysteresis
- On and off delay timers
- Auto reset or latching modes
- Reverse phase output and/or panel indicator
- Selection of alternate list of setpoint values
Plug-in cards also facilitate bus communications. These include RS232,
RS485 and MODBUS (Consult factory for other bus formats). Readout values
and setpoint alarm values can be controlled via bus commands. Additionally, the
meter has features that allow a remote computer to directly control the outputs
of the meter. This is useful during commissioning phases and diagnostic use.
With a communication card installed, set-up software allows configuration from
a PC. The configuration data can be saved to a file for later recall.
A linear DC output signal is available as a Plug-in card. The card provides
either 20 mA or 10 V signals. The output can be scaled independent of the input
range.
The features of the linear output card are:
- Output tracks either input, totalizer, max or min readings
- Programmable output update times
Once the meter has been initially configured, the parameter list may be
locked out from further modification in its entirety, or only the setpoint values
can be made accessible.
The meter has been specifically designed for harsh industrial environments.
With NEMA 4X/IP65 sealed bezel and extensive testing of noise effects to CE
requirements, the meter provides a tough yet reliable application solution.

The 7558 series meters can be fitted with up to three optional plug-in cards.
However, only one card from each function type can be installed at a time. The
function types include Setpoint Alarms, Communications, and Analog
Output. The cards can be installed initially or at a later date. Each optional
plug-in card is shipped with installation and programming instructions.
SETPOINT ALARMS PLUG-IN CARDS
The 7558 series has four setpoint alarm output plug-in cards. Only one of
these cards can be installed at a time. (Logic state of the outputs can be reversed
in the programming.) These plug-in cards include
Dual relay, FORM-C, Normally open & closed
Quad relay, FORM-A, Normally open only
Isolated quad sinking NPN open collector
Isolated quad sourcing PNP open collector
SERIAL RS485 PLUG-IN CARD
An RS485 communication port can be installed with the serial RS485 plug-
in card. The RS485 option allows the connection of up to 32 meters or other
devices (such as a printer, PLC, HMI, or a host computer) on a single pair of
wires not longer than 4,000 feet. The address number of each meter on the line
can be programmed from 0-99. Data from the meter(s) can be interrogated or
changed and alarm outputs can be reset by sending the proper command string.
The function keys and user inputs can be programmed to send data to a printer
or other device via serial communications.
SERIAL RS232 PLUG-IN CARD
An RS232 communication port can be installed with the serial RS232 plug-
in card. The RS232 is intended to allow only 2 devices, not more than 50 feet
apart, to communicate to each other (such as a printer, PLC, HMI, or host
computer). Data from the meter(s) can be interrogated or changed and alarm
outputs can be reset by sending the proper command string. The function keys
and user inputs can be programmed to send data to a printer or device via serial
communication.
MODBUS PLUG-IN CARD
A MODBUS communication port can be installed with the MODBUS plug-
in card. The MODBUS card uses standard MODBUS protocol, which allows
the integration of devices of different types and manufacturers within a common
communication framework.
ANALOG OUTPUT PLUG-IN CARD
Either a 0(4)-20 mA or 0-10 V retransmitted linear DC output is available
from the analog output plug-in card. The programmable output low and high
scaling can be based on the input max, min, or total display value. Reverse
acting output is possible by reversing the scaling point positions.
UNITS LABEL KIT
Each meter has a units indicator with backlighting that can be customized
using the Units Label Kit. The backlight is controlled in the programming.
PC SOFTWARE (SFPAX)
The SFPAX is a Windows based program that allows configuration of the
7558 meter from a PC. Using SFPAX makes it easier to program the 7558 meter
and allows saving the 7558 program in a PC file for future use. On-line help is
available within the software. A 7558 serial plug-in card is required to program
the meter using the software.
Installation
The 7558 meets NEMA 4X/IP65 requirements for indoor use 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 and
cardboard sleeve from the unit and
discard the cardboard sleeve. 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
The unit should be installed in a location that does not exceed the maximum
operating temperature and provides good air circulation. Placing the unit near
devices that generate excessive heat should be avoided.
The bezel should be cleaned only with a soft cloth and neutral soap product.
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate
the aging process of the bezel.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate
the keypad of the unit.

The meter has three jumpers that must be set prior to applying power. The
three jumpers are Bridge Excitation, Input Range, and User Input Logic. The
Jumper Selections Figure is an enlargement of the jumper area shown below.
To access the jumpers, remove the meter base from the meter case by firmly
squeezing and pulling back on the side rear finger tabs. This should lower the
latch below the case slot (which is located just in front of the finger tabs). It is
recommended to release the latch on one side, then start the other side latch.
Bridge Excitation
One jumper is used to select bridge excitation to allow use of the higher
sensitivity 24 mV input range. Use the 5 V excitation with high output (3
mV/V) bridges. The 5 V excitation also reduces bridge power compared to 10
V excitation.
A maximum of four 350 ohm load cells can be driven by the internal bridge
excitation voltage.
Input Range
One jumper is used to select input range. The value selected in programming
must match the jumper setting. Select a range that is high enough to
accommodate the bridge output to avoid overload.
User Input Logic Jumper
One jumper is used for the logic state of all three user inputs. If the user
inputs are not used, it is not necessary to check or move this jumper.

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 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.) 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 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 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 or a 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.
c. Connect the shield to common of the unit 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 away 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 #1VR3
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.

3.2 INPUT SIGNAL WIRING
Before connecting signal wires, the Input Range Jumper should be verified for proper position.
3.3 USER INPUT WIRING
Before connecting the wires, the User Input Logic Jumper should be verified for proper position. If User Inputs are
not used, then skip this section. Only the appropriate User Input terminal has to be wired.
DEADLOAD COMPENSATION
In some cases, the combined deadload and liveload output may exceed the
range of the 24 mV input. To use this range, the output of the bridge can be
offset a small amount by applying a fixed resistor across one arm of the bridge.
This shifts the electrical output of the bridge downward to within the operating
range of the meter. A 100 K ohm fixed resistor shifts the bridge output
approximately -10 mV (350 ohm bridge, 10 V excitation).
Connect the resistor between +SIG and -SIG. Use a metal film resistor with
a low temperature coefficient of resistance.
BRIDGE COMPLETION RESISTORS
For single strain gage applications, bridge completion resistors must be
employed externally to the meter. Only use metal film resistors with a low
temperature coefficient of resistance.
Load cells and pressure transducers are normally implemented as full
resistance bridges and do not require bridge completion resistors.

PROGRAMMING MODE ENTRY (PAR KEY)
The Display Mode is the normal operating mode of the meter. 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 hardware lock.
PARAMETER MODULE ENTRY (ARROW & PAR KEYS)
The Programming Menu is organized into modules. These modules group
together parameters which are related in function. The display alternates
between Pro and the current parameter module. The arrow keys (F1 and F2) are
used to select the desired parameter module. The displayed module is entered
by pressing the PAR key.
PARAMETER MENU MOVEMENT (PAR KEY)
Each parameter module has a separate module menu (which is shown at the
start of each parameter module discussion). The PAR key is pressed to advance
to a particular parameter without changing the programming of preceding
parameters. After completing a module, the display will return to Pro NO.
Programming may continue by accessing additional parameter modules.
SELECTION/VALUE ENTRY (ARROW & PAR KEYS)
In the parameter module, the display will alternate between the current
parameter and the selections/values for that parameter. The arrow keys (F1 and
F2) are used to move through the selections/values for that parameter. By
pressing the PAR key, the displayed selection is stored and activated. This will
also advance the meter to the next parameter.
PROGRAMMING MODE EXIT (DSP KEYor at Pro NO PAR KEY)
The Programming Mode is exited by pressing the DSP key (from anywhere
in the Programming Mode) or 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 a parameter was just changed, the PAR key should be pressed
to store the change before pressing the DSP key.
PROGRAMMING TIPS
It is recommended to start with Parameter Module 1. If lost or confused while
programming, press the DSP key and start over. When programming is
complete, it is recommended to record the parameter programming on the
Parameter User Chart and lock-out parameter programming with a user input or
lock-out code.
FACTORY SETTINGS
Factory Settings may be completely restored in Parameter Module 9. This is
a good starting point when experiencing programming problems. Some
parameters can be left at their Factory Settings without affecting basic start-up.
These parameters are identified throughout the Module explanations. Try the
Factory Settings for these parameters unless a specific selection or value is
known.
ALTERNATING SELECTION DISPLAY
In the explanation of the parameter modules, the following dual display with
arrows will appear. It is 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.

SELECTION
Select the input range that corresponds to the external signal. This selection
should be high enough to avoid input signal overload but low enough for the
desired input resolution. This selection and the position of the Input Range
Jumper must match.
SCALING POINTS*
Linear - Scaling Points (2)
For linear processes, only 2 scaling points are necessary. It is recommended
that the 2 scaling points be at opposite ends of the input signal being applied.
The points do not have to be the signal limits. Display scaling will be linear
between, and continue past, the entered points up to the limits of the Input
Signal Jumper position. Each scaling point has a coordinate-pair of Input Value
( ) and an associated desired Display Value ( ).
Nonlinear - Scaling Points (Greater than 2)
For non-linear processes, up to 16 scaling point may be used to provide a
piece-wise linear approximation. (The greater the number of scaling points
used, the greater the conformity accuracy.) The Input Display will be linear
between scaling points that are sequential in program order. Each scaling point
has a coordinate-pair of Input Value (INP) and an associated desired Display
Value (dSP). Data from tables or equations, or empirical data could be used to
derive the required number of segments and data values for the coordinate pairs.
In the SFPAX software, several linearization equations are available.
Select the decimal point location for the Input, MAX and MIN displays. (The
TOT display decimal point is a separate parameter.) This selection also affects
and x parameters and setpoint values.
502010
521
Rounding selections other than one cause the Input Display to ‘round’ to the
nearest rounding increment selected (ie. rounding of ‘5’ causes 122 to round to
120 and 123 to round to 125). Rounding starts at the least significant digit of
the Input Display. Remaining parameter entries (scaling point values, setpoint
values, etc.) are not automatically adjusted to this display rounding selection.
SCALING STYLE
If Input Values and corresponding Display Values are known, the Key-in
() scaling style can be used. This allows scaling without the presence of a
live input signal. If Input Values have to be derived from the actual input signal
source or simulator, the Apply ( ) scaling style must be used.
INPUT VALUE FOR SCALING POINT 1
For Key-in (Key), enter the known first Input Value by using the arrow keys.
(The Input Range selection sets up the decimal location for the Input Value).
For Apply (APLY), apply the input signal to the meter, adjust the signal source
externally until the desired Input Value appears. In either method, press the
PAR key to enter the value being displayed. The DSP key can be pressed
without changing the previously stored INP1 value in the APLY style.
FILTER SETTING*
The input filter setting is a time constant expressed in tenths of a second. The
filter settles to 99% of the final display value within approximately 3 time
constants. This is an Adaptive Digital Filter which is designed to steady the
Input Display reading. A value of ‘0’ disables filtering.
FILTER BAND*
The digital filter adapts to variations in the input signal. When the variation
exceeds the input filter band value, the digital 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 digital filter
permanently engaged.

General Notes on Scaling
1. Input Values for scaling points should be confined to the limits of the Input
Range Jumper position.
2. The same Input Value should not correspond to more than one Display Value.
(Example: 20 mA can not equal a display of 0 and 10.)
This is referred to as readout jumps (vertical scaled segments).
3. The same Display Value can correspond to more than one Input Value.
(Example: 0 mA and 20 mA can equal a display of 10.)
This is referred to as readout dead zones (horizontal scaled segments).
4. For input levels beyond the first programmed Input Value, the meter extends
the Display Value by calculating the slope from the first two coordinate pairs
(INP1 /dSP1 &INP2 /DSP2). If INP1 – 4 mA and DSP1 – 0, then 0 mA
would be some negative Display Value. This could be prevented by making
INP1 – 0 mA / dSP1 – 0, INP2 – 4 mA / dSP2 – 0, with INP3 – 20 mA /
dSP3 – the desired high Display Value. The calculations stop at the limits of
the Input Range Jumper position.
5. For input levels beyond the last programmed Input Value, the meter extends
the Display Value by calculating the slope from the last two sequential
coordinate pairs. If three coordinate pair scaling points were entered, then the
Display Value calculation would be between INP2 /dSP2 &INP3 /DSP3.
The calculations stop at the limits of the Input Range Jumper position.

The three user inputs are individually programmable to perform specific
meter control functions. While in the Display Mode or Program Mode, the
function is executed the instant the user input transitions to the active state.
The front panel function keys are also individually programmable to perform
specific meter control functions. While in the Display Mode, the primary
function is executed the instant the key is pressed. Holding the function key for
three seconds executes a secondary function. It is possible to program a
secondary function without a primary function.
In most cases, if more than one user input and/or function key is programmed
for the same function, the maintained (level trigger) actions will be performed
while at least one of those user inputs or function keys are activated. The
momentary (edge trigger) actions will be performed every time any of those
user inputs or function keys transition to the active state.

RELATIVE/ABSOLUTE DISPLAY
This function switches the Input Display between Relative and Absolute.
The Relative is a net value that includes the Display Offset Value. The Input
Display will normally show the Relative unless switched by this function.
Regardless of the display selected, all meter functions continue to operate based
on relative values. The Absolute is a gross value (based on Module 1 DSP and
INP entries) without the Display Offset Value. The Absolute display is selected
as long as the user input is activated (maintained action) or at the transition of
the function key (momentary action). When the user input is released, or the
function key is pressed again, the input display switches back to Relative
display. AbS (absolute) or rEL (relative) is momentarily displayed at transition
to indicate which display is active.
Note:In the following explanations, not all selections are available for both
user inputs and front panel function keys. Alternating displays are shown
with each selection. Those selections showing both displays are available for
both. If a display is not shown, it is not available for that selection. USr-1
represents all three user inputs. F1 represents all five function keys including
the secondary function.
The Zero Display provides a way to zero the Input Display value at various
input levels, causing future Display readings to be offset. When activated
(momentary action), rESEt flashes and the Display is set to zero. At the same
time, the Display value (that was on the display before the Zero Display) is
subtracted from the Display Offset Value and is automatically stored as the new
Display Offset Value (oFFSt). If another Zero (tare) Display is performed, the
display will again change to zero and the Display reading will shift accordingly.
