Q: how can LIXISE sx440 generator voltage regulator to adjust?


A:LIXISE sx440 generator voltage regulator a parallel unit with half wave phase voltage regulator, sx440 generator voltage regulator Main features: voltage regulation is better than that of 1%, can be an external potentiometer for fine-tuning, the output voltage with low frequency protection (also reduce as low frequency excitation current) and a LED indicates a low frequency condition, simple external current transformer can automatically adjust the power factor, to the stability of the different level of power generators have different selection and selection of 50/60 hz, etc.

Characteristic: can be simple external current transformer for power factor adjustment (small scale), can also be connected in parallel unit dedicated LSM206 power factor controller, to achieve a wide range of automatic adjustment, greatly improved the electrical loss, indirect reduced fuel consumption

Installation:


Step 1 - sx440 the installation of the generator voltage regulator


1. According to the following data in a suitable position opening, suggest using antiskid self-locking screw to install.

Ranks as one of the four mounting holes distance is: 115 mm * 130 mm, and the installation hole diameter is 5.5 mm

2. According to the following connection mode one-to-one connections

K1, K2: for magnetic switch, when not in use should be short circuit jumper.

P2 and P3: magnetic field power input terminals.In generator for 380 v any item and the center line of 220 v

3, 2: to detect the power input terminals.Can be connected to P2 and P3

1, 2: for an external VR closed to adjust potentiometer, resistance to 1 k ohm, when not in use should be short circuit jumper.

X, XX: XX the X + end magnetic field, magnetic field - end.

S1, S2: DROOP CT (current transformer) input.

A1, A2: VAR/PF control input (V/TRIM).

A, B, C, A, C jumper under 90 kw, 90 kw to 550 kw jumper B, C, A and B jumper over 550 kw.

J1 ~ J8: choose jumper 2-3, 4, 5, 6 and 7.


Step 2 - sx440 generator voltage regulator of debugging


1. Set the low frequency protection: (under normal circumstances do not recommend to adjust)

Check whether frequency selective jumper in a suitable position.

Start the generator, regulate the generator speed to low frequency protection action value of ideal.

Slowly adjust the U/F fine-tuning, LED red light flashing can be used to protect.

(The factory default normal 50 hz 40 hz protection, 60 hz 55 hz protect)

2. The voltage regulation

Can be adjusted by the VOLT on the SX440 fine-tuning, or use an external VR (1 ~ 2) to adjust.

For external adjustment please in SX440 "1" and "2" a resistor across pin 1 kw, if do not need to external, "1" and "2" should be short circuit jumper.

Set out in the generator during adjustment did not start before dispatch SX440 VOLT fine-tune counterclockwise to the end, and then the outer VR to the middle position.

Start the generator, speed regulating normal first.

Slow to adjust the SX440 VOLT or external VR potentiometer, the voltage to the ideal value.

This time if the voltage is not stable, please slow to adjust the SX440 STAB, stabilize voltage step by step.

Note: STAB adjusted too congress to make voltage instability, too small will cause the big load voltage change is too big.When adjusting the STAB, please use pointer meter on both ends of the "X" and "XX" detection voltage shaking the hours is the best position.

3. The reactive power regulation (DROOP)

When a remote voltage under load will be slightly down, through current transformer CT of S1, S2 to compensate, when 1 a CT secondary S1, S2, PF0.8 by adjusting DROOP when maximum compensation 0 to 5% of the rated voltage.

Voltage TRIM: in a VAR/PF controller output signal to the A1, A2 terminal to fix on the SX440 SX440 set voltage, clockwise adjust the TRIM for the maximum range, whereas the smallest.

4. Ex.

When the generator set for the first time use or residual magnetism disappear or magnetic field line X, XX the poles is reversed, because of the remanence voltage is less than 3.5 VAC, enough to reduce voltage SX440 established, please stop the generator and the following:

Stop generator, to remove X, XX on attachment, using a set of 3 ~ 12 v dc power supply, the anode received the generator field X, the cathode string a current limiting resistor receives generator field XX, duration of not more than 3 seconds.

Dismantle SX440 on DC is negative, start the generator to the rated speed when measuring the remanence voltage at the generator output is more than 3.5 VAC, if more than please stop generator and restore SX440 correct wiring;Such as residual magnetism is not more than 3.2 VAC, please again excitation.

Note: can be damaged by excessive excitation SX440 and generator excitation coil, please try to use small current, voltage dc power supply for excitation.
