appropriate preventive measures.
3. 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 2 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 connections against unauthorized persons must be taken into
consideration.

4 Edition 01.A.002/06.16 IO.PMS-620N
3.1 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 located on the housing and report the damage to the manufacturer.
Attached with the unit please find:
- User’s manual;
- Warranty.
3.2 ASSEMBLY
- Disconnect the power supply prior to starting assembly.
- Check the connections are wired correctly prior to switching the unit on.
To install device on the wall, a pinholes should be made. Figure 3.1 presents dimensions of
the device and distances between holes. The back side of the device has four mounting holes.
This part of the case should be mounted to a wall by screws.
Figure 3.1. Device and assembly dimensions
3.3 CONNECTION METHOD
- 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).

IO.PMS-620N Edition 01.A.002/06.16 5
- 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 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 RS-485 serial transmission
connections.
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 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).

6 Edition 01.A.002/06.16 IO.PMS-620N
Connection of the power supply, and the measurement and controlling signals should be
made by screw connectors mounted inside the housing.

Figure 3.8. 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 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.

PMS-620N meter has no galvanic separation between measurement input and RS-485
interface. If serial connection of multiple units is made or serial connection with other device,
without galvanic separation of RS-485 interface, is made then RS-485 interface separators
must to be used certainly (Figure 3.12, 3.13). If RS-485 interfaces are isolated or not used
then the separators are not necessary.

3.4 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.

5. 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.
5.1. 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 5.1, 5.2).
Figure. 5.1. Definitions of measurement 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” and “Hi r”
parameters, paragraph ”inPt” menu).
Figure. 5.2. Definitions of measurement ranges in mode 0 ÷ 20mA
i
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.

IO.PMS-620N Edition 01.A.002/06.16 13
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).
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).
i
Configurations of the device (via menu or RS-485 interface) do not stop measures.
5.2. DETECTION OF THE PEAK VALUES
The PMS-620N controller is equipped with peaks detection function. It can detect 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 5.3). 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.
The relays/LEDs can be controlled depend on the current value of input signal or the peak
value (see ”HOLd” menu).
Figure 5.3. Process of peaks detection

14 Edition 01.A.002/06.16 IO.PMS-620N
5.3. 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.
i
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 5.4) 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 5.5) 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 5.4. One threshold control of the relay/LED outputs
Figure 5.5. Two threshold control of the relay/LED outputs
i
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.

IO.PMS-620N Edition 01.A.002/06.16 15
5.3.1. One threshold mode
Figure 5.6 presents the principle of relay outputs operation for one threshold mode, and
example values of other parameters.
Figure 5.6. 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 5.6 a). The relay can change his state only when input value exceeds (over or under)
border value and tA, tB, tC, tDtimes (Figure 5.6) 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 5.6 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 BON, DON,
Figure 5.6 a, d, e). Similarly, the relay will be turned off if time “toFF” elapse since the input signal
value exceeds any of the border values (see points BOFF, DOFF, Figure 5.6 a, d, e).
If tA,tB,tCor tD(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 5.6 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 5.6 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.

16 Edition 01.A.002/06.16 IO.PMS-620N
5.3.2. Two thresholds mode
Figure 5.7. Principle of LED/relay output operation for two thresholds mode
Figure 5.7 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 threshold 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 5.7).
i
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).

IO.PMS-620N Edition 01.A.002/06.16 17
6. 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).
i
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.
6.1. PROGRAMING MENU

Press [ENTER] at least 2 seconds to accept the changes, after that question ”SEt?” is
displayed, and user must to confirm (or cancel) the changes. To conform changes (and story it in
EEPROM) press [ENTER] button shortly after ”SEt?” is displayed. To cancel the changes press [ESC]
button shortly after ”SEt?” is displayed. After that device returns to the menu.
6.2.2. Numeric parameters (slide change mode)
In “slide change” mode („Edit”=”Slid”), buttons [^] and [v] has different functions.
To increase edited value press (or press and hold) [^] button only, the increasing became
quickest as long as button [^] is pressed. To slow down the increasing, button [v] can be used. If [v] is
pressed shortly (and button [^] is still pressed), increasing slow down for a moment only, if [v] is
pressed and held while button [^] is still pressed the increasing slow down and will be kept on lower
speed.
To decrease edited value press (or press and hold) [v] button only. The decreasing became
quickest as long as button [v] is pressed. To slow down the decreasing, button [^] can be used. If [^] is
pressed shortly (and button [v] is still pressed), decreasing slow down for a moment only, if [^] is
pressed and held while button [v] is still pressed the decreasing slow down and will be kept on lower
speed.
Press [ENTER] at least 2 seconds to accept the changes, after that question ”Set?” is
displayed, and user must to confirm (or cancel) the changes. To conform changes (and story it in
EEPROM) press [ENTER] button shortly after ”SEt?” is displayed. To cancel the changes press [ESC]
button shortly after ”SEt?” is displayed. After that device returns to the menu.
6.2.3. Switch parameters (”LIST” type)
Switch parameters can be described as sets of values (lists) out of which only one of the
options available on the list can be selected for the given parameter. Options of switching parameter are
selected using [^], [v] keys.
Short pressing of [ENTER] causes in displaying of the acknowledge question (”SEt?”). If key
[ENTER] is pressed again, the changes are accepted, stored in EEPROM end the edition process
finished. Pressing the key [ESC] after ”SEt?” causes in cancelling of made changes and returning to
menu.
Functions of buttons when editing numeric and switching parameters:
While editing numeric parameter:
• change of current (flashing) digit;
• slide change of value (acceleration, deceleration, direction change).
While editing switch parameter - selection of switch parameter.
If numerical parameter is being edited, a short press of [ENTER] button change edited
position. A long press of [ENTER] button (at least 2 sec.) causes of display a ”SEt?”
ask, which allow user to make sure if change of the parameter value is correct.
If switch parameter is being edited, a short press of [ENTER] button causes of display
a ”SEt?” ask. When [ENTER] button is pressed again (while ”SEt?” is displayed) the
new value of the parameter is stored in EEPROM memory.
Pressing this button operator can cancel the changes done up to now (if they were not
approved by [ENTER] button after the ”SEt?” ask) and come back to menu.
