1 DESCRIPTION AND OPERATION

1.1 APPLICATION

The PEF-319 universal automatic electronic phase switching device is designed to supply an industrial and

domestic single phase 230/240 V, 50 Hz load from three-phase four-wire mains 3х380+N in order to maintain

uninterrupted power supply of essential single-phase loads and protect them against unallowable voltage variations

in the mains.

According to the voltage presence and voltage quality on the phases, the PEF-319 will automatically select the

optimum phase in limits range set by user and switch the single phase load supply to this phase:

-If power is less than 6,6 kW (30 A), the load is energized directly from the PEF-319;

- if power is more than 6,6 kW (30 A), the PEF-319 controls the magnetic starters (MS) single phase coils of the

corresponding power (MS are not included in supply complete package).

The maximum and minimum voltage limits are set by user.

1.4 DESIGN AND PRINCIPLE OF OPERATION

The electronic phase switch PEF-319 is a microprocessor-based digital device.

User should make setting of trip threshold limits of PEF-319 - the minimal and maximal voltage values at which

PEF-319 trips and switches off the load (or switches over to a reserve phase).

Phase L1 is the priority one. It means that at normal parameters of voltage on all phases connected to PEF-319

(L1, L2, L3), the load will always be energized from phase L1. If on L1 the value is out of limits set by user, PEF-

319 switches the load to the nearest by priority phase in not more than 0,2 seconds if the its voltage corresponds to

the normal level. If the voltage on the reserve phases does not correspond to the trip set limits the load switches off.

Switching to the phases having the unallowable parameters will not be performed.

After the load had been switched to the reserve phase and the voltage parameters had been restored on the

priority phase, the load will be switched to the priority phase in return time Тr (from 5 to 200 sec) set by user.

During the phase switching there can be a flickering of the red LED indicator ALARM and there will be a short

time indication of alarm code on the display (for example, code “Х 3”means that the switching was performed from

the phase L3).

NOVATEK-ELECTRO

PEF-319

If during count down of Тrthe voltage on priority phase goes out of threshold limits, the timer of

Тrwill be reset.

If Тris in the position “∞”, the return to the priority phase will be performed only when voltage on the reserve

phase goes out of the threshold limits.

In case when the voltage supplied on load goes lower than the minimal threshold limit the load switching over or

switching off should be performed with a time delay of 12 seconds. When the voltage goes higher than the maximal

threshold limit or goes 30 V lower than the minimal threshold limit, the load switching over or switching off will be

performed with time delay of 0,2 seconds.

During the load switching off the PEF-319 continues to perform the voltage control on all phases.

When the voltage normalizes within the limit range on one of the phases the PEF-319 will switch the load to this

phase within the time period of Тon.

The additional relay will switch on if the load is connected to any phase and provides the voltage commutation

less than 30 A.

The additional relay terminals are insolated and designed for enhancement of device functional possibilities.

PEF-319 is designed with an internal blocking system against sealing of relay output inbuilt contacts and with

control of state of magnetic starters power contacts in external circuit (the terminal 1is used for sealing control,

figure 3). If at least one contact is switched on («sealed»), PEF-319 will be blocked, the phase switching over is not

performed, the red LED indicator ALARM is flickering and the green LED indicator shows the phase on which the

sealing took place, and the digital display will for a short time show the code of alarm and number of relay (MS) of а

sealed phase (for example, code “Х2” means a sealed contact on phase L2).

Unblocking of PEF-319 should be made by its de-energizing.

NOTE –There will be no switching over in case of energy presence on terminal 1.

2 INTENDED USE

2.1 PRELIMINARY STARTING PROCEDURE

All connections should be made only with the device being de-energized.

Make connection of PEF-319 to the three-phase line according to the figure 2 (at load value less than 30 A) or

according to the figure 3 (at load value more than 30 A with use of magnetic starters).

The limit values should be set after connecting the device to the mains with the load being disconnected:

UMIN –the minimal voltage level of relay switching on;

UMAX –the maximal voltage level of relay switching on;

Тon –time of automatic reset of load after restoring the voltage parameters on one of the phases, and time of

load primary switching on after energizing of the device;

Тr- time of return to the priority phase.

For the refrigerators, air conditioning devices and other compressor equipment, Тon is recommended to be set

in range of 3 -10 minutes, for other devices –according to their manuals and operating instructions.

After the setting of threshold limit values the device is ready for operation with load.

It is allowed to change the levels of UMIN, UMAX, Тon, Тr during the device operation with observing the

safety rules.

2.2 INTENDED USE

After connection to power supply and parameters setting the PEF-319 is ready for operation.

Green light LED indicators L1, L2, L3 on the front panel show the phase to which the load is connected.

With load being connected the digital display shows the voltage of the phase which is connected to the load.

With load being disconnected the digital display shows the voltage of the phase which has the value nearest to

the set threshold voltage limits. This phase is indicated by flickering of corresponding LED indicator.

If the load is disconnected from all three phases, the red LED indicator ALARM will light on

In case when several PEF-319 devices are used in the line, it is recommended to select different phases as a

“priority one” for different groups of consumers to avoid the phase overloading.
