The TLC Series meter is equipped with one current input 0-20 / 4-20mA and one voltage input 0-5 /
1-5 / 0-10 / 2-10V. Current input has an overcurrent protecon circuit, which protects standard resistor. The
selecon of acve input is realized by soware, and the selected input can be changed at any me.
Addionally, the meter allows user to select a conversion characterisc of several kinds: linear, square,
square root, user defined (max.20 points length) and volume characteriscs of a cylindrical tank in the vercal
and horizontal posion. Result is shown on 4-digit LED display. Displayed values range can be selected by
user, from -999 to 9999, plus decimal point.
The device can be equipped with two relay (or OC type) outputs. The device is equipped with RS-485 /
Modbus RTU communicaon interface and sensor supply output. The meter can be ordered in three power
supply versions.
The device has 4 buons being used for main presets programming. To get high protecon level, the
keyboard is mounted under a transparent cover. To allow user to change presets without opening the cover,
an IR sensor is located on front. Remote controller keyboard is equivalent to the device keyboard (Note: The
remote controller is not a part of the TLC Series set – it is an addional piece of equipment).
The TLC Series can be used for controlling and regulaon of processes that require proporonal and
threshold control such as: temperature, level, valve control.

4. DEVICE INSTALLATION
4.1. UNPACKING
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
characteriscs installaon of the unit must be conducted correctly and according to the local regulaons.
Aer removing the unit from the protecve packaging, check for transportaon damage. Any
transportaon damage must be immediately reported to the carrier. Also, write down the unit serial number
located on the housing and report the damage to the manufacturer.
4.2. ASSEMBLY
Read the basic safety requirements on page 3 prior to starng the installaon.
Ensure that the power supply network voltage corresponds to the nominal voltage stated on the unit's
idenficaon label.
The load must correspond to the requirements listed in the technical data.
All installaon works must be conducted with a disconnected power supply.
Protecng the power supply connecons against unauthorized persons must be taken into consideraon.
To install device on the wall, pinholes
should be made. Figure 4.1 presents
dimensions of the device and
distances between holes. The back
side of the device has four mounng
holes. This part of the case should be

4.3. CONNECTION METHOD
Due to possible significant interference in industrial installaons appropriate measures
assuring correct operaon of the unit must be applied. To avoid the unit of improper
indicaons keep recommendaons listed below.
Installaon should be conducted by qualified personnel. During installaon all available safety
requirements should be considered. The fier is responsible for execung the installaon according
to this manual, local safety and Federal regulaons.
The unit is not equipped with an internal fuse or power supply circuit breaker. Because of this, an
external me-delay cut-out fuse with a small nominal current value must be used (recommended
bipolar, max. 2A) and a power supply circuitbreaker 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 destrucon with an
electrical installaon fuse.
Wiring must meet appropriate standards and local regulaons and laws.
In order to secure against accidental short circuit the connecon cables must be terminated with
appropriate insulated cable ps.
Tighten the clamping screws. The recommended ghtening torque is 0.5 Nm.Loose screws can
cause fire or defecve operaon. Over ghtening can lead to damaging the connecons inside the
units and breaking the thread.
In the case of the unit being fied with separable clamps they should be inserted into appropriate
connectors in the unit, even if they are not used for any connecons.
Unused terminals (marked as n.c.) must not be used for connecng any connecng cables (e.g. as
bridges), because this can cause damage to the equipment or electric shock.
If the unit is equipped with housing, covers and sealing to protect against water intrusion, pay
special aenon to their correct ghtening or clamping. In the case of any doubt consider using
addional prevenve measures (covers, roofing, seals, etc.). Carelessly executed assembly can
increase the risk of electric shock
Aer the installaon is completed do not touch the unit's connecons when it is switched on,
because it carries the risk of electrical shock.

Due to possible significant interference in industrial installaons appropriate measures
assuring correct operaon of the unit must be applied. To avoid the unit of improper indicaons
keep recommendaons listed below. To avoid the unit of improper indicaons keep
recommendaons listed below.
Avoid running signal cables and transmission cables together with power supply cables and cables
controlling inducve loads (e.g. contactors). Such cables should cross at a right angle.
Contactor coils and inducve loads should be equipped with interference protecon systems, e.g.
RC-type.
Use of screened signal cables is recommended. Signal cable screens should be connected to the
earth or ground only at one end of the screened cable.
In the case of magnecally induced interference the use of twisted pair of signal cables is
recommended. Twisted pair (best if shielded) must be used with RS-485 serial transmission
connecons.
In the case of measurement or control signals are longer than 100 Feet or go outside of the building
then addional safety circuits are required.
In the case of interference from the power supply side the use of appropriate interference filters is
recommended. Bear in mind that the connecon between the filter and the unit should be as short
as possible and the metal housing of the filter must be connected to the earth with the largest
possible surface. The cables connected to the filter output must not be run with cables with
interference (e.g. circuits controlling relays or contactors).
Connecon of the power supply, and the measurement and controlling signals should be
made by screw connectors mounted inside the housing.

4.4. MAINTENANCE
Figure 4.3. Method of connecting cables to the clamping connectors
The unit does not have any internal replaceable or adjustable components available to the user. Pay
attention to the ambient temperature in the room where the unit is operating. Excessively high
temperatures can cause faster aging of the internal components and shorten the fault-free time of the unit's
operation. In cases where the unit gets dirty do not clean with solvents. For cleaning use warm water with
small amount of detergent or in the case of more signicant contamination ethyl or isopropyl alcohol.
Using any other agents can cause permanent damage to the housing.

6. PRINCIPLE OF OPERATION
6.1. MEASUREMENT MODE
After turning the power supply on, device ID and software version are shown on the display, next the
controller will go into the measurement mode.
In the measure mode, the measurement results, converted over selected characteristic, are displayed on the
LED display. The measurement range equal to the nominal range is called: nominal measurement range, and
the measurement range equal to the extended nominal range is called: permissible measurement range
(Figure 6.1, 6.2).
If the measurement value does not exceed permissible measurement range but displayed value
exceeds range -999 - 9999, the warning "-Ov-" is displayed rather than the calculated value.
In the measurement mode user can check main threshold values. After pressing [^] or [v] button, name of
the threshold (e.g. "rEL1") and the value will be displayed on the display in an alternating mode. If [^] or [v]
is pressed within 5 sec, the next threshold will be displayed, otherwise the device will return to the
measurement mode. If a free access is enabled (see description of "SECu" menu), user can change the value
of particular threshold pressing button [ENTER] (see : PARAMETERS EDITION).
Input type, range of displaying values, characteristic of conversion, decimal point position, and measure
ltering ratio, are user congurable parameters. All accessible parameters can be changed by entering the
menu (see: DEVICE PROGRAMMING). Use the local keyboard or the remote controller to do it. (Note: All
parameters can be remotely changed via RS-485 interface).
Conguration of the device (via menu or RS-485 interface) does not stop the measurements.

6.2. DETECTION OF THE PEAK VALUES
6.3. CONTROL OF THE RELAY OUTPUTS
If device is not equipped with one or more relay outputs, menus refer to the relays being available,
but apply to LED indicators only. In such case LEDs indicates exceeding of particular thresholds but
no relay will be activated.
The TLC Series controller is equipped with a peak detection function. It can detect the peak of the input
signal and display the values. Presets connected with this function are placed in a "HOLd" menu (see
description of "HOLd" menu). The detection of the peak can be done if the measured signal raises and
drops in value at least equal to parameter "PEA". Detected peaks are displayed during the time dened by
parameter "timE". If a new peak is detected while the current one is displayed, this new peak will be
displayed and display time counter will be cleared (Figure 6.3). If no peaks are detected while time "timE"
elapses, device starts to show the current value of input signal once again. If "HdiS"="HOLD" then setting
parameter "timE"=0.0 causes holding peak value until [ESC] button is pressed. If "HdiS"="rEAL" then value
"timE"=0.0 means no holding. Displaying peak value is signalized by ashing most right decimal point.
The relays/LEDs can be controlled depending on the current value of input signal or the peak value (see
"HOLd" menu).
The control of the input (Fluid) (measured signal) is realized via relay outputs. Front panel LEDs named "R"
indicates the state of particular relay output.
Modes of the control can be changed depending on the values of parameters "SEtP", "SEt2", "HYSt",
"modE", "t on", "toFF", " unit" and "AL". Depending on "modE" parameter, relays can be not used or
controlled over one or two thresholds values.
If one threshold is used (Figure 6.4) the relay can be turned on ("modE" = "on") or o ("modE" = "oFF")
when the input signal value is contained in zone A. If two thresholds are used (Figure 6.5) the relay will be
turned on when value of input signal is contained in zone A ("modE" = "in") or zone B ("modE" = "out") and
turned o if the signal is contained in the second one.

7.3. MENU DESCRIPTION
7.3.1. “rEL1” menu
Due to problem with direct displaying of “m” and “K” letters, they are exchanged with
special signs “ “ for “m” and “ “ for "K" respectively. However, the user manual letters "m" and
"K" are used to make it more readable (example:“modE”, “ tc K”).
This menu allows conguring the operation mode of relays and LEDs marked "R” (e.g. "R1”).
If there are few relay outputs available, then every output has its own conguration menu (e.g. menu "rEL2”
for relay (LED) "R2”). Principle of the relays operation is described in paragraph CONTROL OF THE RELAY OUTPUTS.
The relay outputs and LEDs (named R) can be controlled depend on both – the current value and
the peak value (when peak detection is active) of the input signal.

ENTER
If numerical parameter is being edited, a short quick pressing of [ENTER] button will
change edited position. A long press of [ENTER] button (at lest 2 sec.) the display to
request ”SEt?” conrm, which allow user to make sure the change of the parameter
value is correct. If switch parameter is being edited, a short press of [ENTER] button
causes the display a ”SEt?” conrmation. When [ENTER] button is pressed again (while
”SEt?” is displayed) the new value of the parameter is stored in EEPROM memory.
Pressing this button the operator can cancel the changes done up to now (if they
were not approved by [ENTER] button after the ”SEt?” request) and will return to
the main menu.
Password checking. If the password is dierent from "0000", then the number
(password must be entered to enter main menu) follows the entering of password. If
entered password is correct then rst menu position will be displayed otherwise the
warning "Err", and unit returns to measurement mode.
“- - - -”
First threshold of the relay (range -999 - 9999). Negative values can be input by
selecting a “-” sign on rst digit (to change value use [^] and [v] buttons).
Threshold is the median value of relay hysteresis.

"modE" - relay operation mode:
Presented parameters should be set to ensure that ”SEtP” + ” H Y S t ”, ”SEt2” + ”HYSt”, ”SEtP” -
”HYSt” or ”SEt2” - ”HYSt” does not exceed the measure range. Additionally, in the two
threshold mode (“modE”= "in” or "out”), the hysteresis for both thresholds must not overlap one
another (in other case relay will not change state).
Second threshold of the relay (range -999 - 9999). Negative values can be input by
selecting a “-” sign on rst digit (to change value use [^] and [v] buttons). This
threshold is accessible when ”modE” parameter is set to "in” or "out” value.
Threshold is the median value of relay hysteresis.
"SEt2"
Hysteresis of relay (range 0 - 999). Full hysteresis of the relay is equal to 2x “HYSt”
parameter. The relay state can change when an input signal is out of threshold
hysteresis to threshold+hysteresis zone.
"HYSt"
The relay is not active (permanently turned o)
"noAC"
One threshold mode - the relay is turned ON when input signal exceeds the SEtP +
HYSt value, and is turned o when the input signal becomes lower than SEtP – HYSt,
"on"
One threshold mode - the relay is turned OFF when input signal exceeds SEtP +
HYSt value, and is turned on when the input signal becomes lower than SEtP – HYSt,
"oFF"
Two threshold mode - the relay is turned ON when the input signal is greater than
“lower threshold +HYSt” and below than “bigger threshold HYSt”, and turned o
when the input signal is contained within the second zone. The hanger threshold
equals the hanger one of “SEtP” and “SEt2” thresholds, the smaller threshold”
means the smaller one of “SEtP” and “SEt2” thresholds.
"in"
Two threshold mode - relay is turned ON when the input value is greater than
“bigger threshold + HYSt” and lower than “smaller threshold – HYSt”, and turns
on when the input signal is contained in the second zone. The hanger threshold
means hanger one of “SEtP” and “SEt2” thresholds, the Smaller threshold” means
smaller one of “SEtP” and “SEt2” thresholds.

• LEDs lights up when relays are closed, independently of relays' mode.
• When the power supply fails, the unit does not store relays state selected by RS- 485 interface.
If time when the input signal exceeds some border value and is shorter than the “t on” or
“toFF” time, the relay does not change its state (see paragraph: CONTROL OF THE RELAY
OUTPUTS).
The relay is controlled via RS-485 interface, independently on the input signal.
"modb"
Turn on the delay time- the relay is turned on with delay equal “t on” if the input
value exceeds the appropriate border value (dened with threshold and
hysteresis), “t on” time. “t on” range 0 - 99.9, dened with 0.1 sec. resolution. Unit of
this parameter is set by“unit” parameter.
"t on"
Turn o delay time- the relay is turned o with delay equal “toFF” if the input value
exceeds appropriate border value (dened with threshold and hysteresis), “toFF”
time. “toFF” range 0 - 99.9, dened with 0.1 sec. resolution. Unit of this parameter is
set by “unit” parameter.
"toFF"
Unit of time for“t on” i “toFF” parameters. The unit be set to one of two values:
"unit" "min"
minutes
"SEC"
seconds
This parameter denes the relay reaction when some critical situations occurs:
If parameter “modE” is set to “on” , “oFF”, “ in” or “Out” the “critical situation” means that the
allowable measurement range is exceeded. If parameter "modE" is set to "modb", the
"critical situation" means the communication delay (when no data is received) is longer than
"mbtO" parameter (see description: "rS" menu).
"AL"
"noCH"
relay does change state,
"on"
relay will be turned on,
"oFF"
relay will be turned o.
