2. GENERAL CHARACTERISTICS
The SWE-73-A is a simple digital panel indicator, equipped with two measurement inputs.
One current input ( -2 /4-2 mA) and one voltage input ( -5/1-5/ -1 /2-1 V). Current input has
additionally overcurrent protection circuit, which protects standard resistor.
The selection of active input is realised by software, and selected input can be changed
at any time. Additionally the SWE-73-A allows user to select a conversion characteristic of
several kinds: linear, square, square root, and user defined (max.2 points length). Result is
showed on 4-digit LED display. Displayed values range can be selected by user, from -999 to
9999, plus decimal point. Device SWE-73-A is equipped with RS-485 / Modbus RTU
communication interface .
The measurement range, active input and other parameters can be selected while
ordering. The device can be configured via IR remote controller or, optionally by PC via
RS-485 interface, or using simple RS-232 to IR converter. Moreover communication interface
RS-485 enables data transmission in any monitoring system equipped witch Modbus RTU
protocol.
Easy assembling, small dimensions, precision and reliability are the basic trumps of SWE-73-
A indicators.
IR remote controller is not a part of the SWE-73-A and must be ordered separately.

4. DEVICE INSTALLATION
The unit has been designed and manufactured in a way assuring a high level of user
safety and resistance to interference occurring in a typical industrial environment. In order to
take full advantage of these characteristics installation of the unit must be conducted correctly
and according to the local regulations.
- Read the basic safety requirements on page 3 prior to starting the installation.
- Ensure that the power supply network voltage corresponds to the nominal
voltage stated on the unit’s identification label.
- The load must correspond to the requirements listed in the technical data.
- All installation works must be conducted with a disconnected power supply.
- Protecting the power supply clamps against unauthorized persons must be
taken into consideration.
4.1. UNPACKING
After removing the unit from the protective packaging, check for transportation damage. Any
transportation damage must be immediately reported to the carrier. Also, write down the unit
serial number on the housing and report the damage to the manufacturer.
Attached with the unit please find:
- user’s manual,
- warranty,
- assembly brackets - 2 pieces.
4.2. ASSEMBLY
- The unit is designed for mounting indoor inside housings (control panel,
switchboard) assuring appropriate protection against electric impulse waves.
Metal housing must be connected to the grounding in a way complying with the
governing regulations.
- Disconnect the power supply prior to starting assembly.
- Check the correctness of the performed connections prior to switching the unit on.
In order to assembly the unit, a 67 x 32.5 mm mounting hole (Figure 4.1) must be
prepared. The thickness of the material of which the panel is made must not exceed
5mm. Place the unit in the mounting hole inserting it from the front side of the panel,

4.3. CONNECTION METHOD
Caution
- Installation should be conducted by qualified personnel . During installation all
available safety requirements should be considered. The fitter is responsible for
executing the installation according to this manual, local safety and EMC
regulations.
- The unit is not equipped with an internal fuse or power supply circuit breaker.
Because of this an external time-delay cut-out fuse with minimal possible nominal
current value must be used (recommended bipolar, max. 2A) and a power supply
circuit-breaker located near the unit. In the case of using a monopolar fuse it must
be mounted on the phase cable (L).
- The power supply network cable diameter must be selected in such a way that in
the case of a short circuit of the cable from the side of the unit the cable shall be
protected against destruction with an electrical installation fuse.
- Wiring must meet appropriate standards and local regulations and laws.
- In order to secure against accidental short circuit the connection cables must be
terminated with appropriate insulated cable tips.
- Tighten the clamping screws. The recommended tightening torque is .5 Nm.
Loose screws can cause fire or defective operation. Over tightening can lead to
damaging the connections inside the units and breaking the thread.
- In the case of the unit being fitted with separable clamps they should be inserted
into appropriate connectors in the unit, even if they are not used for any
connections.
- Unus d clamps (mark d as n.c.) must not b us d for conn cting any
conn cting cabl s ( .g. as bridg s), b caus this can caus damag to th
quipm nt or l ctric shock.
- If the unit is equipped with housing, covers and sealing packing, protecting
against water intrusion, pay special attention to their correct tightening or clamping.
In the case of any doubt consider using additional preventive measures (covers,
roofing, seals, etc.). Carelessly executed assembly can increase the risk of electric
shock.
- After the installation is completed do not touch the unit’s connections when it is
switched on, because it carries the risk of electrical shock.
Du to possibl significant int rf r nc in industrial installations appropriat m asur s
assuring corr ct op ration of th unit must b appli d. To avoid th unit of improp r
indications k p r comm ndations list d b low.
–Avoid common (parallel) leading of signal cables and transmission cables together with
power supply cables and cables controlling induction loads (e.g. contactors). Such cables
should cross at a right angle.
–Contactor coils and induction loads should be equipped with anti-interference protection
systems, e.g. RC-type.

User manual for digital indicator with U/I input SWE-73-A
–Use of screened signal cables is recommended. Signal cable screens should be
connected to the earthing only at one of the ends of the screened cable.
–In the case of magnetically induced interference the use of twisted couples of signal
cables (so-called “spirals”) is recommended. The spiral (best if shielded) must be used
with RS-485 serial transmission connections.
–In the case of interference from the power supply side the use of appropriate anti-
interference filters is recommended. Bear in mind that the connection between the filter
and the unit should be as short as possible and the metal housing of the filter must be
connected to the earthing with largest possible surface. The cables connected to the filter
output must not run in parallel with cables with interference (e.g. circuits controlling relays
or contactors).
Connections of power supply voltage and measurement signals are executed using the
screw connections on the back of the unit’s housing.

enter to main menu follows the entering of password. If entered password is
correct then first menu position will be displayed else warning ”Err”, and unit
returns to measurement mode.
Due to problem with direct displaying of “m” letter, it is exchanged with special sign
“ “. Independently in user manual letter „m” is used to make it more readable
(example: “modE”).
.3.1. “inPt” menu
This menu presets the measurement input:
“tYPE" - type of the input / sensor. This parameter can be set to values:
”0-20”, “4-20”- current inputs.
”0-10”, “2-10”, ”0-5”, “1-5”- voltage inputs.
Displayed values are defined by parameters “Lo C”,”Hi C” (or by user defined
characteristic points) and parameter ”Pnt”.
”CHAr” - this option presets type of the conversion characteristic, and can be set to:
”Lin” - linear
“Sqr” - square
“Sqrt” - square root
When one of those characteristics is chosen display
range is defined by “Lo C” and “Hi C”.
“USEr” - user defined characteristic. Maximal length 2 points. Every point is
defined by user. Adding, Editing and Deleting of points is done by options
„AddP”, „EdtP”, „dELP” („InPt” menu) respectively.
If user defined characteristic is selected, and if number of defined points is lower
than 2 then warning ”Errc” is displayed in measurement mode.
The process of displayed result calculation is described in details in DISPLAY VALUES
CALCULATION paragraph.
”FiLt” - this parameter sets filtration rate. It can be set to values from (no filtration ) to 5
(strongest filtration – time window about 2 sec).
”Pnt” - decimal point position. It can be set to one of:
“ 0”, “ 0.0”, “ 0.00”, “0.000”
Decimal point position is changed by [^], [v] buttons.

“Lo C”
“Hi C”
These parameters describe the values displayed for minimum and maximum input
current. For example, if input type is set to 4-2 mA “Lo C” parameter defines the
value displayed when input current is equal 4 mA, and “Hi C” parameter defines
the value displayed for 2 mA of input current. Available range for these
parameters: -999 ÷ 9999. Negative values can be set by entering '-' sign on the first
position (by use of [^], [v] buttons).
If user defined characteristic is selected (parameter “CHAr” = ”USEr”) the
parameters „Lo C” and „Hi C” are not available for modification, due to their values
are calculated from defined characteristic.
“AddP” - this menu allow user to add single point to the user defined characteristic.
After selection of this option device waits for „X” and „Y” coordinates of new point.
Modification of the coordinates is done accordingly to numerical parameters edition.
Coordinate „X” defines the percentage ratio of input current to selected current
range. The „X” range: -99,9 ÷ 199,9. Coordinate „Y” defines displayed value for
particular „X” value. The „Y” value can be changed in range: -999 ÷ 9999, decimal
point position depend on „Pnt” parameter (menu ”inPt ”).
• User can not enter two points with the same value of „X” coordinate. If user trays
to do it, ”Err” warning is displayed. To modify any defined point use ”EdtP”
option.
• To distinguish „X” and „Y” coordinates, if „X” coordinate is displayed an
additional decimal point on utmost right position is displayed.
• If user defined characteristic is selected, and if number of defined points is lower
than 2 then warning ”Errc” is displayed in measurement mode.
“dELP” - this option allows user to delete any of the points of the user defined
characteristic. After selection current number of points of the user defined
characteristic is displayed for about approx. 1.5 sec. After that device waits for
selection of point being deleted (by [^], [v] buttons). The short pressing of [ENTER]
button causes by switching between X and Y value of the displayed point. The long
press (press and hold at least 2 sec) of [ENTER] button causes by displaying
„dEL?” ask. If [ENTER] button is pressed again, current point is deleted and new
updated number of points of the user defined characteristic is displayed.
“EdtP” - this option allows user to modify of particular point of the user defined
characteristic. After selection current number of points of the user defined
characteristic is displayed for about approx. 1.5 sec. After that device waits for
selection of point being edited (by [^], [v] buttons). The short pressing of [ENTER]
button causes by switching between X and Y value of the displayed point. The long
press (press and hold at least 2 sec) of [ENTER] button causes by entering to edit
the selected coordinate of the point. Modification of the coordinates is done
accordingly to numerical parameters edition.
“AddP”, ”dELP” and “EdtP” options are available only if the user defined
characteristic is used (it means when parameter “CHAr” = ”USEr”).
“Lo r”, ”Hi r” - these parameters define the expansion of nominal range in percent. They

determine the permissible range of input signal (Figure 7.1).
The permissible range allow user to exceed the nominal range of input signal.
If input value is contained in the permissible range a proper result is displayed.
If input signal exceeds this range (defined by “Lo r” and “Hi r”), “-Lo-” or “-
Hi-” warning is displayed depend on input signal value.
Fig re 7.1 Example of definition of permissible range of inp t signal -
“Lo r” and “Hi r” parameters (“4-20” mode)
The “Lo r” parameter is important if input is set to “4-20”, “1-5” or “2-10” mode
only, and determines lower border of the permissible range. If input is set to
“0-20”, “0-5” or “0-10” mode then lower border of the permissible range is
always .
For example if input is set to “4-20” mode, then lower border is calculated due to
expression: Imin = 4 mA - 4 mA × “Lo r” %.
The “Lo r” value can be set from to 99.9%.
Parameter “Hi r” determines the upper border of the permissible range accordingly
to the expression (for all modes).
For example if input is set to “4-20” mode, then upper border is calculated due to
expression: Imax = 2 mA + 2 mA × “Hi r” %.
The value of “Hi r” can be set from to 19.9%
In example no 1 of the DISPLAY VALUES CALCULATION paragraph the
procedure of the permissible input range determining is presented in details.
If the measurement value do not exceeds permissible measurement range but
displayed value exceeds range -999 ÷ 9999, the warning ”-Ov-” is displayed rather
than the calculated result.

This parameter allows user to set bright of the LED display, bright can be set to
conventional values from 1 to 8.

.3.3. ”HOLd” menu
This menu contains parameters connected with peak detection function. See also full
description of the peak detection function in paragraph: DETECTION OF THE PEAK VALUES
“modE” - the type of detected changes of the input signal, can be set to values:
”norm” - peaks, peak and next drop of the input signal of value equal at least “PEA”,
”inv” - drops, drop and next peak of the input signal of value equal at least “PEA”,
“PEA” - minimal detected signal change classified as peak or drop (see Figure 6.3)
“timE” - maximum time of displaying of the peak (drop) value, can be set from .1 to 19.9
sec, with .1 sec. resolution
“HdiS” - type of displayed values:
”rEAL” - current value is displayed,
”HOLd” - peak (drop) value is displayed,
.3.4. ”Scod” parameter
This parameter defines user password (4-digits number). If this parameter is set at value
“0000”, user password is turned off.
If th us r do not r m mb r his password, th acc ss to th m nu is possibl
by th “on -us password”. To g t this password pl as contact with
Mark ting Division. “Singl us password” can b us d only on tim , aft r
that it is d stroy d. Ent ring this password caus s in cl aring of us r
password, it m ans s ts th us r password to „0000”.
The “one-use password” can be used ONE TIME ONLY, it is impossible to use it
again! The “one-use password” can be restored by Service Division only.
.3.5. ”rS” menu
This menu is connected with RS-485 interface, and sets his properties:
”Addr” - this parameter defines the address of the device, accordingly to Modbus protocol.
It can be set in range from to 199. If the value is set then device, responds to
frames with address 255 (FFh).
”bAud” - this parameter determines RS-485 interface baud rate. It can be set to one of 8
possible values: ”1.2”, ”2.4”, ”4.8”, ”9.6”, ”19.2”, ”38.4”,”57.6”,”115.2”, which
respond to the baud rates of 12 , 24 , 48 , 96 , 192 , 384 , 576 and
1152 bit/s respectively.
