In order to monitore 2 levels of voltage, it is possible to select
if output relay will respond to each level individually (see

Function description
Relay is designated to monitor 3-phase circuits. Type HRN-43N controls voltage against neutral wire, type HRN-43 controls interphase voltage. Relay can monitor voltage in two levels (overvoltage/
undervoltage), phase assymetry , sequence and failure. Each faulty state is indicated by individual LED. By DIP switch (No.3) it is possible to define function of the other relay – independayt function
(1x for overvoltage, 1x for undervoltage) or in parallel. Time delays t1(fixed) – when changing from faulty to normal state or when de-energized and t2 (adjustable) when changing from normal to
faulty state. These delays prevent incorrect conduct and oscillation of output device during short voltage peaks in the main or during gradual voltage decline into normal.
Voltage control
Set upper level Umax in range 138-276 V (or 240 - 480 V for HRN-43) and lower level Umin in range 35-99% Umax. In case any phase passes this range, after a delay which eliminated short voltage
peaks, contact breaks. output contact again switches after returning back into monitored voltage range and exceeding fixed hysteresis (which is adjustable in two values by DIP switch).
Phase sequence
monitors correctness of phase sequence. In case of unwanted change output contact breaks. In case of energization of a device with incorrect phase sequence, contact stays open.
Asymmetry
Rate of assymetry between individual phases is set in a range of 5-20%. In case set asymmetry is exceeded, output relay breaks and LED indicating asymmetry shines. Delays t1, t2 and hysteretic are
applicable when returning to normal state.
