INTRODUCTION
The PMVF52 equipment has been designed as an Interface Protection System (SPI) in accordance with the CEI 0-21 standard.
It can be applied to all LV micro-generation systems (photovoltaic, wind) where it is used to control the Interface Switch (IS) between generation system and public grid.
In the event of problems on the grid (e.g. due to maintenance), the system intervenes in a timely fashion, opening the Interface Switch (e.g. contactor) and isolating the generation system.
In the event of Interface Switch (IS) failure, it can also control a backup device to disconnect the generation system in any case.
The equipment features 5 digital inputs permitting the connection of the system to the signals provided by the network operator to meet the requirements of the current regulations.
The functions implemented and the possibility of further expansion ensure that it is prepared for any developments to the protection system.
The PMVF52 equipment is supplied already programmed and assembled. With the factory settings, once the connections have been made, it is already ready for operation in compliance with the requirements of the
CEI without requiring any further settings to be made. It is nevertheless prepared for any future changes to the operating parameters. Changes to the settings are password protected, preventing tampering by
unauthorised personnel.

COMMANDS MENU
– The Commands Menu is used to perform occasional operations, like resetting measurements, counters, alarms, etc.
– If the Advanced-level access password was entered, the Commands Menu can also be used to perform automatic operations useful for configuring the instrument.
– The following table shows the functions which are available with the Commands Menu, divided according to the required access level.
CODE COMMAND ACCESS DESCRIPTION
LEVEL
C.01 RESET HI-LO User / Advanced Resets the HI and LO values of all measurements
C.02 RESET TRIP COUNTERS User / Advanced Resets the trip counters
C.12 PARAMETERS TO DEFAULT Advanced Restores all settings to factory default values
C.13 PARAMETER BACKUP Advanced Saves a backup copy of the settings
C.14 PARAMETERS RESTORE Advanced Reloads the settings from the backup copy
C.15 TEST THRESHOLD 27.S2 Advanced Temporarily shifts threshold 27.S1 to permit testing of threshold 27.S2 ∂.
C.16 AUTOTEST Advanced PMVF52 performs the self-test function according to the procedure described in the standard
C.17 RESET EVENTS LOG Advanced Reset of events log
C.18 ALARM INHIBITION Advanced Temporarily disables alarms A02 to A05 ∑.
∂ The purpose of command C.15 is to permit testing of threshold 27.S2 via relay test kit. This threshold is normally “covered” by 27.S1 and consequently cannot be tested according to the procedures
indicated by the standard. Giving this command sets threshold 27.S1 temporarily to the minimum permitted value (20% Un), lower than the default value of 27.S2 (40%Un) so as to permit it to be tested.
This shift in the threshold lasts for a maximum of 5 minutes, during which the shifted value is visible on the Active Thresholds page. Switching the PMVF52 off then on or waiting for the period to elapse
(sufficient for performing the test) brings threshold 27.S1 back to its normal set value.
∑ The purpose of command C.18 is to temporarily disable the alarms A02-A05 to facilitate the initial commissioning phase, without having to disconnect the PMVF52 each time.
Disabling lasts up to 120 min. and is canceled by switching off the device.
The count can be viewed on the synoptic page.

ALARM INDICATIONS
– In the event of an anomaly, the PMVF52 indicates the situation with a pop-up window.
– If the user presses buttons on the front, the alarm is hidden temporarily to permit consultation of the screens.
– The alarm remains while the anomaly is present.
– All the alarms/warnings except A01 are retentive, i.e. they reset when the anomaly ceases and after having disconnected and subsequently powered up the device again. Retentive alarms always open the
OUT1 IS output.
ATTENTION: If the autotest is performed and it has a negative outcome, it will show the relevant alarm A06. This alarm is retentive and it’s not reset until the autotest is successfully passed.
– In the presence of a non-retentive alarm, the equipment continues to operate in any case.
– Exit OUT3, OUT4 and OUT5 can be programmed to indicate the presence of any alarm (global alarm function).
SELF-DIAGNOSIS
– The PMVF52 features a series of self-diagnosis checks. If any of these checks is unsuccessful, a window displaying the text System Error Exx is displayed, where xx indicates the reason for malfunction.
Should this indication occur, contact our Technical support (Tel. + 39 035 4282422; E-mail: [email protected]), stating the code indicated.
CODE ALARM / INDICATION DESCRIPTION / POSSIBLE CAUSES
A01 EXTERNAL SIGNAL / LOCAL CONTROL COMBINATION NOT PERMITTED External Signal and Local Control both OFF (combination not envisaged by the standard). The Local Control must be
ON (shunted) if required by the operating regulations.
If the Local Control is OFF, then the External Signal must be ON.
A02 IS OPENING FAILURE The SPI sends the opening command to the IS, but the auxiliary (feedback) contact is closed, so the SPI sends an
opening command to the backup.
Check the operation of the IS and of its auxiliary (feedback) contact.
A03 IS CLOSING FAILURE – The SPI has ordered the closing of the IS but it does not close (check OUT1 wiring and/or IS coil).
– The auxiliary IS contact (feedback) is not working.
– The auxiliary IS contact (feedback) is not connected correctly to terminal INP1.
– The auxiliary IS contact (feedback) is not fitted since it is not envisaged in the scheme.
Disable alarm A03 by setting P06.03 to OFF.
Note: LOVATO Electric recommends the use of the feedback input.
A04 BACKUP OPENING FAILURE The IP sends the opening command to the back-up but the auxiliary contact (feedback) is closed.
Check the functionality of the support and its auxiliary contact (feedback).
A05 BACKUP CLOSING FAILURE The IP has commanded the closing of the backup but it does not close (check wiring OUT1 and / or IS coil).
– The auxiliary contact of the backup (feedback) does not work.
– The auxiliary contact of the backup (feedback) is not correctly connected to the relative programmed terminal
as "Backup feedback".
– The auxiliary contact of the backup (feedback) is not mounted because it is not foreseen in the diagram.
A06 AUTOTEST The autotest function has failed.
COMMUNICATION
– The PMVF52 can be fitted with an optional standard communication module from those listed below. When a communication module is installed, it must be configured through the dedicated M05 -
COMMUNICATION Menu on page 8.
– The protocol currently supported is Modbus in the RTU, ASCII and TCP variants.
– The equipment is already prepared for communication in accordance with the IEC/EN/BS 61850, possible via installation of a dedicated module.
