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 inside housings (control panel, switchboard)
insuring appropriate protection against surges and interference. Metal housings
must be connected to ground in a way that complies with the governing
regulations.
- Disconnect the power supply prior to starting assembly.
- Check the connections are wired correctly prior to switching the unit on.
In order to install the unit, a 67 x 32.5 mm mounting hole (Figure .1) must be

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 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 clamps (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 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.
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 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.
–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- 85 serial transmission connections.
–In the case of measurement or control signals are longer than 30m 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 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).

6. PRINCIPLE OF OPERATION
After turning the power supply on, device ID and software version are showed on the
display, next the controller goes to 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).
Fig re 6.1. Definitions of meas rement ranges in mode 4 ÷ 20mA
If the result of measurement exceeds the permissible measurement range, warning ”-Hi-” or
”-Lo-” is displayed rather than input signal, depends on exceeded value (see description of
“Lo r” i “Hi r” parameters, paragraph ”inPt” menu).
Fig re 6.2. Definitions of meas rement ranges in mode 0 ÷ 20mA
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.

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 remote changed
via RS- 85 interface).
Configuration of the device (via menu or RS 85 interface) do not stops measures.
6.2. DETECTION OF THE PEAK VALUES
The -30 controller is equipped with peaks detection function. It can detect a peaks of
the input signal and display their values. Presets connected with this function are placed in
”HOLd” menu (see description of ”HOLd” menu). The detection of the peak can be done if
the measured signal raises and drops of value at least equal to parameter ”PEA”. Detected
peaks are displayed during the time defined by parameter ”timE”. If a new peak will be
detected while 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 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.

value displayed when input current is equal mA, and “Hi C” parameter defines
the value displayed for 20 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 volume characteristics of a cylindrical tank is selected (parameter “CHAr” = ”tn
v” or “CHAr” = ”tn h”) the parameters „Lo C” and „Hi C” are not available.
„t h1”, „t h2”, „t h3”, „t d” - the parameters defining shape of cylindrical tank
(Figure 7.1 and Figure 7.2).
a) for the cylindrical tank in the vertical position:
„t h1” - the height of the bottom part of a tank (in the elliptic paraboloid shape), this
parameter has the fixed precision - 2-decimal point,
„t h2” - the height of the middle part of a tank in the cylindrical shape, this parameter has
the fixed precision - 2-decimal point,
„t h3” - the height of the top part of a tank (in the elliptic paraboloid shape), this
parameter has the fixed precision - 2-decimal point,
„t d” - the diameter of the middle part of a tank, this parameter has the fixed precision -
- 2-decimal point,
b) for the cylindrical tank in the horizontal position:
„t h1” - the length of the left bottom of a tank (in the elliptic paraboloid shape), this
parameter has the fixed precision - 2-decimal point,
„t h2” - the length of the middle part of a tank in the cylindrical shape, this parameter has
the fixed precision - 2-decimal point,
„t h3” - the length of the right bottom of a tank (in the elliptic paraboloid shape), this
parameter has the fixed precision - 2-decimal point,
„t d” - the diameter of the middle part of a tank, this parameter has the fixed precision -
- 2-decimal point,
„t Sn”, „t Sh” - parameters defining the length and position of the sensor used to measure
level of liquids, gases or solids in the tank (Figure 7.1, 7.2).
„t Sn” - distance between end of the sensor and bottom of the tank, this parameter has
the fixed precision 2-decimal point but the unit is 100 times smaller than “t Sh”
(see Info below),
„t Sh” - the measuring range, this parameter has the fixed precision - 2-decimal point.

•The unit value of “t Sn” parameter is 100-fold less than the unit value of
other parameters defining cylindrical tank, i.e. if we set value 10.00 in
“t Sh” parameter and set value 08.00 in "t Sn" parameter this mean that
value of “t Sn” parameter is real has 00.08 value in preserved unit of the
“t Sh” parameter.
•If we set parameters of tank in [m] unit (“t Sn” parameter takes [cm] unit
respectively, see above), than displays the result the volume of the tank in
[m3] unit, if we set parameters of tank in [cm] unit (“t Sn” parameter takes
[mm] unit respectively, see above), than displays the result the volume of
the tank in [cm3] unit.
•"t Sh" parameter may be greater than height (for vertical position) or
diameter (for horizontal position) of the tank, which means that the total
volume of the tank can be achieved by eg. such middle-current range,
•If the measurement value do not exceeds permissible measurement range
but displayed value exceeds range of 9999 than you can move to the right
position of the decimal point if it is still possible (see parameter Menu-
>”inPt”->”Pnt”).
•If in the volume characteristics of a cylindrical tank is exceeded the value
of the volume of the tank sets by parameters available in menu "inPt"
instead of the calculated result will be display warning “-Hi-”.
