Installation, connection, setting and servicing must be carried out by qualified electrician staff only, which have perfectly understood the instructions and functions of the device. This device contains protection against overvoltage peaks and disturbing impulses in the power supply network. For the correct function of the protection of this device, there must be suitable protections of higher degrees (A,B,C) installed in front of them and according to the standards, interference of switching devices must be securely eliminated (contactors, motors, inductive loads, etc.). Before installation, make sure that the device is de-energized and the main switch is in the "OFF" position. Don`t install the device to sources of excessive electromagnetic interference. Ensure correct installation by perfect air circulation so that during continuous operation and a higher ambient temperature, the device does not exceed the maximum allowed operating temperature. For installation and setting use a screwdriver with a width of approx 2 mm. Keep in mind that this is a fully electronic device and approach accordingly with the installation. Non-problematic function of the device is also dependent on the previous method of transportation, storage, and handling. In case of any signs of damage, deformation, malfunction, or missing parts, don`t install this device and claim it at the dealer. The product must be treated as electronic waste at the end of its life. Function of output contacts: The function is not applicable in the phase sequence monitoring, the contacts are switched in parallel. DIP switch ,,Output" is ignored. Graphs legend: L1, L2, L3 = 3-phase voltage RESET = memory reset t1 = time delay, fixed t2 = time delay Umax/Umin, adjustable 15-18 = output contact 1 25-28 = output contact 2 LED = phase sequence indication Function of output contacts: The function is not applicable in the phase asymmetry and failure monitoring, the contacts are switched in parallel way. DIP switch ,,Output" is ignored. Graphs legend: L1, L2, L3 = 3-phase voltage RESET = memory reset t1 = time delay, fixed t2 = time delay Umax/Umin, adjustable - adjustable asymmetry level 15-18 = output contact 1 25-28 = output contact 2 LED = asymmetry indication Relay is designated to monitor 3-phase circuits. Type HRN-43 controls the interphase voltage, type HRN-43N controls voltage towards the neutral wire. Relay can monitor: voltage in two levels (overvoltage/undervoltage), phase sequence/failure and asymmetry. Each fault state is indicated by an individual LED. By DIP switch ,,Output" it is possible to select the function of output contacts: independent function (1× for overvoltage, 1× for undervoltage) or in parallel. Fixed time delay (t1) is applied when changing from fault to OK state or when de-energized. Adjustable time delay (t2) is applied, when changing from OK to fault state. This delay prevents incorrect behavior and oscillation of the output device during short-term voltage drops and peaks. Voltage monitoring The upper level Umax is set in the range 138 276 V (resp. 240 480 V for HRN-43) and the lower level Umin in the range of 35 99 %Umax. In case any phase deviates from this set band, after a set delay, output contact opens. Output contact again closes after returning back into the monitored band and exceeding fixed hysteresis (selectable by DIP switch ,,Hysteresis"). In the event of an outage in two or three phases, the output contacts will open immediately, regardless of the set delay t2. Phase sequence Monitors correctness of phase sequence. In case of unwanted change, output contacts open. In case of energization of a relay with incorrect phase sequence, contacts stay open. Asymmetry The level of asymmetry between individual phases is set in the range of 5 20 %. In case set asymmetry is exceeded, output contacts open and LED indicating asymmetry shines. Time delays t1, t2 and hysteresis are applied when returning to OK state. Monitoring asymmetry can be switched off by the DIP switch ,,ASYM".
