4.3. CONNECTION METHOD
Due to possible significant interference in industrial installations appropriate measures
assuring correct operation of the unit must be applied. To avoid the unit of
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 Federal 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 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
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 0.5 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.
Unused terminals (marked as n.c.) must not be used for connecting any connecting 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, 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.

Due to possible significant interference in industrial installations appropriate
measures assuring correct operation of the unit must be applied. To avoid the unit of
improper indications keep recommendations listed below.
Avoid running signal cables and transmission cables together with power supply cables
and cables controlling inductive loads (e.g. contactors). Such cables should cross at a
right angle.
Contactor coils and inductive loads should be equipped with interference protection
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 of the ends of the screened cable.
In the case of magnetically 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 connections.
In the case of measurement or control signals are longer than 100 Feet or go outside of
the building then additional 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 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 earth with the largest possible surface. The cables connected to the filter output must
Connection 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 showed on the display,
next the controller then 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).

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 thresholds 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 filtering ratio, are user configurable 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).
Configuration of the device (via menu or RS-485 interface) Does not stop the measurements.

6.2. DETECTION OF THE PEAK VALUES
The TruVu 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 defined 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 flashing most right decimal point.

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 depend on the values of parameters "SEtP", "SEt2", "HYSt",
"modE", "t on", "toFF", "unit" and "AL". Depend on "modE" parameter, relays can be not used
or controlled over one or two thresholds values.
I
f one threshold is used (Figure 6.4) the relay can be turned on ("modE" = "on") or off
("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 off if the signal is contained in the second one.
