Setpoints for Frequency :

In this menu, Frequency range can be defiend according to High and Low values of Frequency measurement.

If the frequency of the system decreases the Frq Hi value; output is switched on and LED is turned on. (Refer to Output menu) and H LED for frequency is turned off.

If the frequency of the system exceeds the high set value, H LED relating to frequency blinks, output switched off at the end of defined time (Frq Ond), LED turned off (Refer to Output menu) and H LED for frequency is turned on continuously.

If the frequency of system are under the high set value (Frq Hi) as a hysteresis (F-H HyS), output is turned on at the end of defined time (Frq oFd), LED is turned on and H LED is turned off, at the end of the adjusted time (Frq Ofd), output1 LED turns on and Hi LEDs

If the frequency of the system is over the low set value (Frq Lo), output is turned on, LED is turned on L LED is turned off.

If the frequency of the system decreases the low set value (Frq Lo), L LED blinks; output is turned off at the end of defined time (Frq ond). LED is turned off and L LED is turned on continuously.

If the frequency of the system is over the low set value (F-L HyS) as a hysteresis (Frq Hys), output is turned on at the end of defined time (Frq Ofd), LED is turned on and L LED is turned off.

Note: System frequency is measured for L1.

There are 6 submenus.

Frq Hi, Frq Lo, F-H HyS, F-L HyS, Frq Ond, Frq oFd.

Max. value for system frequency, this value can be defined between 0...70.00 Hz. If the value is set to zero (0), the high frequency warning is disabled.

Min. value for system frequency, this value can be defined between 0...70.00 Hz. If the value is set to zero (0), the low frequency warning is disabled.

Note: Attention for common using of output and relay LED for voltage.

In this menu, required hysteresis value can be defined between 0...20.00 Hz. in order to switching off the "high frequency" warning.

In this menu, required hysteresis value can be defined between 0...20.00 Hz. in order to switching off the "low frequency" warning.

Delay-on time for activation of alarm for high and low frequency value. This value can be defined between 000.0, 999.9 in term of second.

Delay-off time for disactivation of alarm for high and low frequency value. This value can be defined between 000.0..999.9 in term of second..

Phase sequence can be turned on/off in this menu. Inversed phase voltage which is applied to the measurement inputs (L1-L2-L3), can be monitored. Default setting is off. In order to let the device to warn user in case of inversed phase situation please change the off position as on in "UoL PHS SEq" menu. Phase sequence function is disabled if the selection is selected off.

L1, L2 and L3 LEDs blink and output output released immediately when "UoL PHS SEq" is turned on and phase sequence is inverted with any reason. Note: Output 2 is used if U-I is selected and Output1 is used if H-L is selected in Output menu for the Phase Sequence monitoring.

Instant Tripping Function. At position ON, if any VL-L / VL-N values exceeds 1.5 times of high voltages (UoL Hi L-1/L-2/L-3) values; the "voltage output" switches OFF instantly, output LED turned OFF and H LED, for related voltage, is turned ON. (Please refer to "Output".)

If any phase voltage decrease 0.5 times low voltages (UoL L-1/L-2/L-3); the "voltage output" switches OFF instantly, output LED turned OFF and Lo LED, for related voltage, is turned ON.

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), this is a stylistic or background line, not a placeholder underscore. Therefore, the OCR result must ignore it and output nothing or only meaningful text. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated underscores where none should exist based on the GT's visual context. Hence, the OCR result is inconsistent with the Ground Truth.

Example : If the connection type is selected as Star

(with neutral); U-H HyS=10V U-H L-1=250V,

U-H L-2=255V, U-H L-3=260V

and then this connection type is selected as Delta

(without neutral), device will change the values after

New values:

U-H L-1 (L 1-L 2 Phase to phase voltage) - 433 V

U H L 2 (L 2 L 3 Phase to phase voltage) - 441 V

U-H L-2 (L2-L3 Phase to phase voltage) = 441 V
U-H L-3 (L3-L1 Phase to phase voltage) = 450 V

U-IT L-S (L3-L1 Phase to phase voltage) = 450 V (YYYY 0 - 10 Y)

There are 6 submenu

In this menu, low set points for voltage values are programmed. Lo values for Phase-Neutral / Phase-Phase (according to Star / Delta selection) can be entered one by one.

If all the voltage values (Phase-Neutral / Phase-Phase) are over the Lo value; released output is switched on, its LED turned on (please refer "Output") and released I LEDs are turned off.

If any of the voltage values (Phase-Neutral / Phase-Phase) decrease the Lo value, L LED blinks and related output is switched off at the end of “delay on time” (U-L ond), its LED turned off (please refer “Output”) and related L LED is turned on continuously. If all voltage (Phase-Neutral / Phase-Phase) values increase the low set value (Lo) as a hysteresis voltage (U-L HyS), related relay is switched on at the end of the “delay off time” (U-L ofd), its LED turned on (please refer “Output”) and L LED is turned off.

Note: Low Voltage values are programmed for (Phase-Neutral / Phase-Phase) separately but "U-L HyS" (hysteresis), "U-L ond" (delay on time) and "U-L ofD" (delay off time) values are common; these parameters have same values for Phase-Neutral / Phase-Phase. When Connection type (Star/Delta) is selected (refer to Connection menu), device will change the U-L L-1, U-L L-2 and U-L L-3 values automatically according to connection.
