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
characteriscs installaon of the unit must be conducted correctly and according to the local regulaons.
Read the basic safety requirements on page 3 prior to starng the installaon.
Ensure that the power supply network voltage corresponds to the nominal voltage stated on the unit's
idenficaon label.
The load must correspond to the requirements listed in the technical data.
All installaon works must be conducted with a disconnected power supply.
Protecng the power supply connecons against unauthorized persons must be taken into consideraon.
4.1. UNPACKING

4.3. CONNECTION METHOD
Due to possible significant interference in industrial installaons appropriate measures
assuring correct operaon of the unit must be applied. To avoid the unit of improper
indicaons keep recommendaons listed below.
Installaon should be conducted by qualified personnel. During installaon all available safety
requirements should be considered. The fier is responsible for execung the installaon according
to this manual, local safety and Federal regulaons.
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 destrucon with an
electrical installaon fuse.
Wiring must meet appropriate standards and local regulaons and laws.
In order to secure against accidental short circuit the connecon 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 defecve operaon. Over ghtening can lead to damaging the connecons inside the
units and breaking the thread.
In the case of the unit being fied with separable clamps they should be inserted into appropriate
connectors in the unit, even if they are not used for any connecons.
Unused terminals (marked as n.c.) must not be used for connecng any connecng 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 aenon to their correct ghtening or clamping. In the case of any doubt consider using
addional prevenve measures (covers, roofing, seals, etc.). Carelessly executed assembly can
increase the risk of electric shock
Aer the installaon is completed do not touch the unit's connecons when it is switched on,
because it carries the risk of electrical shock.

Due to possible significant interference in industrial installaons appropriate measures
assuring correct operaon of the unit must be applied. To avoid the unit of improper indicaons
keep recommendaons listed below. To avoid the unit of improper indicaons keep
recommendaons listed below.
Avoid running signal cables and transmission cables together with power supply cables and cables
controlling inducve loads (e.g. contactors). Such cables should cross at a right angle.
Contactor coils and inducve loads should be equipped with interference protecon 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 magnecally 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
connecons.
In the case of measurement or control signals are longer than 100 Feet or go outside of the building
then addional 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 connecon 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).
Connecon of the power supply, and the measurement and controlling signals should be
made by screw connectors mounted inside the housing.

6. PRINCIPLE OF OPERATION
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.
6.1. 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).
"Lo r" parameter
"Hi r" parameter
nominal measurement range
4 mA 20 mA
permissible measurement range
Figure 6.1. Definitions of measurement ranges in mode 4-20mA
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 congurable 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).
Conguration of the device (via menu or RS-485 interface) does not stop the measurements.

TLC Series
6.2. DETECTION OF THE PEAK VALUES
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 dened 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).

6.3. CONTROL OF THE RELAY OUTPUTS
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.
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.
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.

(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.
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”).
7.3.1. “rEL1” menu
This menu allows conguring 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 conguration 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.
First threshold of the relay (range -999 - 9999). Negative values can be input by
"SEtP"
selecting a “-” sign on rst digit (to change value use [^] and [v] buttons).
Threshold is the median value of relay hysteresis.

another (in other case relay will not change state).
TLC Series
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” o r " out” value.
Threshold is the median value of relay hysteresis.
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.
"modE" - relay operation mode:
"noAC"
"on"
"oFF"
"in"
"out"
The relay is not active (permanently turned o)
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,
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,
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.
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

"modb"
• 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.
"t on"
"toFF"
The relay is controlled via RS-485 interface, independently on the input signal.
Turn on the delay time- the relay is turned on with delay equal “t on” if the input
value exceeds the appropriate border value (dened with threshold and
hysteresis), “t on” time. “t on” range 0 - 99.9, dened with 0.1 sec. resolution. Unit of
this parameter is set by “unit” parameter.
Turn o delay time- the relay is turned o with delay equal “toFF” if the input value
exceeds appropriate border value (dened with threshold and hysteresis), “toFF”
time. “toFF” range 0 - 99.9, dened with 0.1 sec. resolution. Unit of this parameter is
set by “unit” parameter.
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).
"unit"
"AL"
Unit of time for “t on” i “ toFF” parameters. The unit be set to one of two values:
"min"
"SEC"
This parameter denes the relay reaction when some critical situations occurs:
"noCH"
"on"
"oFF"
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).

These parameters describe the values displayed for minimum and maximum input
current. For example, if input type is set to 4-20 mA "Lo C" parameter denes the value
displayed when input current is equal to 4 mA, and "Hi C" parameter denes the value
displayed for 20 mA of the input current highest value. Available range for these
parameters: -999 - 9999. Negative values can be set by entering '-' sign on the rst

For example if input is set to “4-20” mode, the lower border is calculated to expression: Imin = 4 mA
- 4 mA × “Lo r” %. The “Lo r” value can be set from 0 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 = 20 mA + 20 mA × “Hi
r” %. The value of “Hi r” can be set from 0 to 19.9%
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.

8. THE ALARM LED
The ALARM LED (AL) is turned on when input signal is out of the permissible input range. See parameters: “tyPE”, “ Lo
r” and “Hi r” in paragraph "InPt” menu.
9. OVER-CURRENT PROTECTION
The current input of the device is equipped with over-current protection circuit. This circuit protects the standard
resistor against damage. Maximum input current is set to 40mA (typical). When temperature of the standard resistor
falls, the protection circuit will turn on automatically, and the device will measure the input current again. Due to
thermal phenomenon in the standard resistor, precision of the measurement may be lower until the standard resistor
temperature falls to the environment temperature.
