This is a class A unit. In housing or a similar area it can cause radio frequency
interference. In such cases the user can be requested to use appropriate
preventive measures.
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 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.
- 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 indoor inside housings (control panel,
switchboard) assuring appropriate protection against electric impulse waves. Metal
housing must be connected to the grounding in a way complying with the governing
regulations.
- Disconnect the power supply prior to starting assembly.
- Check the correctness of the performed connections prior to switching the unit on.
In order to assembly the unit, a 66.5 x 32.5 mm mounting hole (Figure 4.1) must be
prepared. The thickness of the material of which the panel is made must not exceed
5 mm. When preparing the mounting hole take the grooves for catches located on
both sides of the housing into consideration (Figure 4.1).

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 minimal possible nominal
current value must be used (recommended bipolar, max. 2 A) 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.

User manual for meter with U/I input PAC-73S

- 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-485 serial transmission connections.
- 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).
Connections of power supply voltage and measurement signals are executed using the screw
connections on the back of the unit’s housing.

Figure 4.9. Connection 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 47 nF/min. 250 V
AC
in series with
100R/5 W 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 unit 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.

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).
Figure 6.1. Definitions of measurement ranges in mode 4 ÷ 20 mA
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).
Figure 6.2. Definitions of measurement ranges in mode 0 ÷ 20 mA
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.
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).

User manual for meter with U/I input PAC-73S

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-485 interface).
Configuration of the device (via menu or RS-485 interface) do not stops measures.
6.2. DETECTION OF THE PEAK VALUES
The PAC-73S 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.
The relays/LEDs can be controlled depend on the current value of input signal or the peak value
(see “HOLd” menu).
Figure 6.3. Process of peaks detection

6.3. CONTROL OF THE RELAY OUTPUTS
The control of the object (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 this relays
are available, but apply to LED indicators only. In such case LEDs indicates
exceeding of particular thresholds.
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.
If 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.
Figure 6.4. One threshold control of the relay/LED outputs
Figure 6.5. Two thresholds control of the relay/LED 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.

Figure 6.6. Principle of LED/relay output operation for one threshold mode
Parameter “SEtP” sets a threshold of the relay, and parameter “HYSt” sets a hysteresis of
the relay (Figure 6.6 a). The relay can change his state only when input value exceeds (over or
under) border value and t

times (Figure 6.6) are bigger than the time defined by
parameters “t on”, “toFF” and “unit”. Border values means values equal
threshold+hysteresis and threshold-hysteresis respectively.
If “t on” and “toFF” parameters are set to “0”, then the relay state will be changed as soon as
input value exceeds any of the border values (see points A and C, Figure 6.6 a, b, c).
If values of “t on” or/and “toFF” are positive, then relay state will be turned on if the input value
exceeds the border values and stay bigger (or lower) during at least “t on” (see points B

,
D

C
or t
D
(when input signal stay in zone A or zone B) are lower than parameters “t on” or
“toFF”, the relay will not change his state (see points A and C, Figure 6.6 a, d, e).
The state of relay output while the input value exceeds the border values (points A, B, C, D) is
described by parameter “modE”. The relay can be turned on (“modE” =“on”), or turned off
(“modE” =“oFF”) when input signal value is contained in zone A (Figure 6.6 a).
The parameter “AL” allow user to set the relay output behaviour in critical situations (e.g. Input
values exceeds permissible measurement range). User can select that the relays will be
turned on, turned off, or not changed in critical situations.
All parameters connected with relay outputs are described in paragraph “rEL1” menu.

Figure 6.7 presents the principle of relay outputs operation for two thresholds mode, and an
example values of other parameters. In this mode parameter “SEt2” is accessible in common
with “SEtP”, this parameter describes a second threshold of the relay output. The parameters
“HYSt”, “modE”, “t on”, “toFF”, “unit” and “AL” are connected with both “SEtP” and
“SEt2” thresholds. While the controlling process, the relay output changes his state depends of
both “SEtP” and “SEt2” thresholds in similar way as it was described in one threshold mode.
If two thresholds mode is used, “modE” parameter defines state of the relay output when the
input value occurs in a particular zone defined by border values of both thresholds. The relay
can be turned on if the input value is contained in zone A (“modE” =“in”) or zone B
(“modE” =“out”) and turned off if it is contained in the second one (Figure 6.7).
The sequence of thresholds “SEtP” and “SEt2” can be set in any order, due to the
control of relay outputs is done depend on difference between thresholds values
(zone A ) and outside of threshold values (zone B).
7. DEVICE PROGRAMMING
The device menu allow user to set all parameters connected to operation of measurement
input, control modes, critical situations behaviour, communication via RS-485 and access
settings. The meaning of the particular parameters is described in paragraph MENU
DESCRIPTION.
Some of the parameters can be accessed without menu entering (quick view mode). 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).
If particular parameter has been changed and confirmed in quick view mode, its new
value is displayed in alternating mode with parameter name by few seconds.
Confirmed changes may be checked or user can switch viewed parameter pressing
[^] or [v] button.
7.1. PROGRAMMING MENU
