5.
control for automatic reset delay setting, Ton (sec);
6.
green LED signal that the mains voltage is present, ON;
7.
green LED signal that load is energized, Load;
8.
red LEDs signal for the mains voltage fault/ magnetic starter (MS) power contacts
9.
monitoring, Fault;
MS power contacts monitoring terminals;
10.
input contacts;
11.

12.
13 terminals for the mode selection: line/phase voltage monitoring.
A RNPP-301 VOLTAGE CONTROL RELAY IS DESIGNED FOR:
monitoring of the tolerable RMS phase/line voltage level (at the option of user) with independent setting
1.
adjustments for the minimum/maximum voltage thresholds;
monitoring of the correct phase sequence and phase “non-coincidence” (the phases are supposed to be
2.
coinciding when a load is energized not from two different phases but instead from one and the same
phase);
monitoring of three phase lines for voltage presence and the mains voltage symmetry with adjustable
3.
phase imbalance setting;
monitoring of the magnetic starter power contacts status at no-load and under load;
4.
the load (
415
V/50Hz) de-energization with user-set trip delay (Toff) through the opening the magnetic
5.
starter coil power circuit (A.C and D.C. electric circuit switching) when fault conditions occur;
the mains voltage quality monitoring after the relay had tripped and did reset automatically with the user-
6.
set reset delay (Ton) upon the voltage parameters regeneration;
all fault conditions (not switching of the magnetic starter power contacts is included) are displayed by
7.
special LEDs indicating the specific cause of the occurring voltage fault in the mains.
