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 a small 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 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.

User manual - METER SUR-W410
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). uch 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. ignal 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 pair of signal cables is
recommended. Twisted pair (best if shielded) must be used with R -485 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 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
not be run 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.

F gure 4.12. Connect on of voltage converters
Temperature sensor can be connected to the device in typical 4-wire circuit (Figure 4.13a) or
3-wire circuit (Figure 4.13b). Due to precision of measurement 4-wire circuit is recommended.
If 2 wire circuit is used, the resistance of wires should be as small as possible, to
avoid of measurement errors. Measured value can be corrected (constant
correction) using „toF ” parameter from menu „inPt”. Due to low precision 2-wire
connection is not recommended.
When 4-wires or 2-wires connection is used, the resistance of particular wires
(Ra ÷ Rd) CAN BE DIFFERENT. When 3-wires connection is used, the resistance of particular
wires (Ra ÷ Rd) MU T BE IDENTICAL to enable proper compensation of it's resistance. The

F gure 4.14. Connect on of power supply and relays
Contacts of relay outputs are not equipped with spark suppressors. While use
the relay outputs for switching of inductive loads (coils, contactors, power
relays, electromagnets, motors etc.) it is required to use additional
suppression circuit (typically capacitor 47nF/ min. 250VAC in series with
100R/5W resistor), connected in parallel to relay terminals or (better) directly
on the load. In consequence of using the suppression circuit, the level of
generated electromagnetic disturbances is lower, and the life of relay contacts
rises.

4.4. MAINTENANCE
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 cause faster ageing 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 significant contamination ethyl or isopropyl
alcohol.
Using any other agents can cause permanent damage to the housing.
Product marked with this symbol should not be placed in municipal waste. Please
check local regulations for disposal of electronic products.

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).
For temperature inputs (TC and RTD) there is linear characteristic available only.
For this kind of inputs nominal measurement range, and permissible
measurement range are the same (no range extension available, Figure 6.3).
F gure 6.1. Def n t ons of measurement ranges n mode 4 ÷ 20mA
If the result of measurement exceeds the permissible measurement range, warning
”-Hi-” or ”-Lo-” is displayed rather than input signal, depending on exceeded value (see
description of “Lo r” and “Hi r” parameters, paragraph ”inPt” menu). The warning can be
effect of measurement circuit malfunction. In that case “-Lo-” means shortcut and “-Hi-”
means break of measurement circuit. If sensor failure will be detected (e.g. broken wires), then
” .Err” warning will be displayed.
F gure 6.2. Def n t ons of measurement ranges n mode 0 ÷ 150mV
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.

F gure 6.3. Def n t ons of measurement ranges n mode Pt100
If the device is equipped with relay outputs, then in the measurement mode user can
check main thresholds values. After pressing [^] or [v] button, name of the threshold (e.g.
”rEL1”) and his value will be displayed on the display in alternating mode. If [^] or [v] will be
pressed in 5 sec again, the next threshold will be displayed, else the device comes back 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).
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 R -485 interface).
Configuration of the device (via menu or R -485 interface)
does not stop measures.
6.1.1. Detection OF THE PEAK VALUES
The UR-W410 meter 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 6.4).
If no peaks are detected while time ”timE” elapses, device starts to show the current
value of input signal again. If „Hdi ”=”HOLD” then setting parameter "timE"=0.0 causes
holding peak value until [E C] button is pressed. If „Hdi ”=”rEAL” then value "timE"=0.0
means no holding. Displaying peak value is signalized by flashing most right decimal point.
The relays/LEDs and analogue outputs can be controlled depend on the current value of
input signal or the peak value (see ”HOLd” menu).
