1.  APPLICATION 

Multifunctional voltage monitoring relay RNPP-311M (hereinafter RNPP-311M) performs the following 

functions:  

  Permissible voltage level control; 

  Control of correct phase sequence, phase loss and phase coincidence; 

  Phase imbalance control (control of full phase power load and phase symmetry); 

  Turning the power load 

OFF

 by operating with output contacts in case of unallowable mains voltage 

parameters. User adjusted Tripping time delay is in the range 0-10 sec (

Toff

); 

  Mains  voltage monitoring after tripping and automatic turning 

ON

 the power  load  when the voltage 

parameters return back to normal conditions. Autoreclosing time delay is adjusted by (

T

on

) user in the range 

0-600 seconds; 

  Alarm indication in case of voltage faults and indication of voltage presence on each phase; 

Using toggle switch (Figure 1; point 4) RNPP-311M user may select the type of the power circuit (400V 

or 415V) and the set of optionally performed functions (using toggle switches 5-8 shown on Figure 1).  

 

 

– Min/Max voltage tripping threshold (

U

/U

min

);

 

– Autoreclosing time delay (

T

on

); 

– Tripping time delay (

T

off

)

 

– Toggle switch: type of power circuit 400V/415V;  

– Toggle switch (ON/OFF): phase sequence control (

SEQ

);  

– Toggle switch (ON/OFF): phase imbalance control (

IMB

); 

– Toggle switch (ON/OFF): Minimal voltage tripping (

U

min

); 

– Toggle switch (ON/OFF): Maximal voltage tripping (

U

max

); 

– Green LED indicators of voltage presence on each phase; 

10 

– Red LED “

ALARM

” indicator showing also the open state of the output contacts; 

11 

– Input terminals 400V/415V; 

12 

– Input terminals 24V (available on request); 

13 

– Output terminals.

It is possible to adjust the RNPP-311M to operate in following modes: 

  complete voltage parameters monitoring; 

  MIN/MAX voltage level monitoring;
