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 fields 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 figure) 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.

If the potential difference between the phases is greater than , the display will show , and after time the relay will be OFF ( ). L2 L1 L3 KLAW. LCD μC ZAS.

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 qualified 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 influence 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.
