PRODUCT FAMILY
The PNM-32 is a member of the PNM
product family.
1. Disconnect power supply by the pha-
se fuse, the circuit-breaker or the
switch- disconnector combined to the
proper circuit.
2. Check if there is no voltage on con-
nection cables by means of a spe-
cial measure equipment.
3. Install the PNM-32 on the TH-35 DIN
rail in the switchboard.
4. Connect the cables with the terminals
in accordance with the installing dia-
gram.
5. Switch on the power supply from the
mains.
WARRANTY CARD
INNER DIAGRAM
In order to cancel the circuit data and set de-
fault values it is necessary, in the main win-
dow, to press and hold simultaneously ( and
) keys for 3 seconds;
All display elds will be lighted;
The main window will be entered after a
while.
FUNCTIONING
After power supply switching on it is necessary to set maximum and minimum voltage, hy-
steresis, phase unbalance and the relay ON-time and OFF-time. If not, the following default
values will be set = 235 V, = 225 V, = 1 V, = 2 s, = 2 s, = 10 V. If all
phase voltages are greater or equal to 170 V, automatic phase sequence checking will start.
In case of incorrect phase sequence the output relay will be switched OFF ( ), the symbol
will be displayed: , and a message with info which phases are to be changed over in or-
der to set a correct phase sequence will be displayed too. If the phase sequence is correct,
the device will start displaying measured voltages in three-second cycles (see the gure)
and voltages controlling.
It is possible to toggle
between the phases by
pressing the cursors
which causes breaking
cyclic phase voltages
display (every 3 s) and
holding the set phase
display for 20 seconds.
If the voltages are in-
cluded within the set range ( , ), after time the relay will be ON ( ). Any voltage
threshold exceeding for the given phase will be signalled by displaying the following sym-
bol: for the minimum threshold and the symbol for the max voltage , and start
counting the time , and then will switch OFF the output relay ( ). If, during displaying
e.g. the L3 phase voltage, the L1 or L2 phase voltage falls below the voltage threshold ,
or exceeds the min , threshold, the device will toggle the phase value displayed actually
to the phase with the incorrect voltage value and will remain in this state until the wrong va-
lue disappears or the relay is OFF. Układ wykrywa również asymetrię napięcia. The device
is capable of detecting voltage unbalance. If the potential difference between the phases is
greater than , the display will show , and after time the relay will be OFF ( ).

* The PNM-32 device is not tted with the True RMS converter and therefore only 50 Hz sinusoidal voltages can be measured correctly;
if there are signicant harmonic distortions, the measurement result error may be serious.
● Three-phase load protection against
voltage swing and unbalance, and
incorrect phase sequence,
● Measured voltage state indicator,
● Relay state indicator,
● The device supplying with any phase,
● Minimum (170 ÷ 225 V) and maximum
(235 ÷ 290 V) voltage setting,
● OFF-time delay adjustment,

The PNM-32 voltage relay is designed
for the three-phase system voltage con-
trol and load protection. It is possible
to set minimum and maximum voltage,
hysteresis, voltage unbalance and ON
/ OFF delay. The device is capable of
detecting voltage unbalance and phase
sequence. The LCD display and keybo-
ard enable easy parameters visualization
and programming.
The device is designed for
three-phase installation and
must be installed in accor-
dance with standards valid
in a particular country. The
device should be connec-
ted according to the details
included in this operating manual. Installa-
tion, connection and control should be car-
ried out by a qualied electrician staff, who
act in accordance with the service manual
and the device functions. Disassembling of
the device is equal with a loss of guarantee
and can cause electric shock. Before in-
stallation make sure the connection cables
are not under voltage. The cruciform head
screwdriver 3,5 mm should be used to in-
stal the device. Improper transport, storage,
and use of the device inuence its wrong
functioning. It is not advisable to instal the
device in the following cases: if any device
part is missing or the device is damaged or
deformed. In case of improper functioning
of the device contact the producer.
