jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
 ;
Wszystko w porządku.
Instrukcja czytelna i kompletna.
Dziękuję.
all right!
thank you.

Instrukcja bardzo czytelna. zawiera co potrzeba. Polecam
When the potential difference between Pin 8 (CSH) and Pin 9 (CSL) of the control IC exceeds 100 mV due to shorting of the load, etc., the control IC internal current restriction circuit stops PWM LOGIC and turns OFF the High side MOD-FET. 3. GC Board (SUB5 V DC-DC converter) The GC board is input with the secondary side output voltage (9.0 ± 2.0 V) of T2101 from when the power supply voltage is input. It steps down the standby voltage 5.0 ± 0.3 V supplied to the microprocessor by the DC-DC converter (IC2500) and outputs it. The GB board receives and transmits the POWER ON signal, and POWER PROT signal. 4. GB Board (D3.3 V DC-DC Converter) The GB board is input with the secondary side output voltage A6 V (5.9 ± 0.3 V) of T2100 when the power is turned ON. It steps-down the D3.3 V (3.3 ± 0.3 V) supplied to the signal circuit using the DC-DC converter (IC2300), and outputs it. 5. GD Board 10.7 V DC-DC Converter and FAN+B1, 2 Regulator The GD board is input with the secondary side output voltage 17.5 V (17.5 ± 0.4 V) of T2100 when the power is turned ON. It steps-down the 10.7 V (10.6 ± 0.3 V) supplied to the signal circuit using the DC-DC converter (IC2700), and outputs it. The GD board is mounted with a regulator (IC2701, IC2702) which inputs the above 10.7 V and steps-down the voltage FAN+B1, 2 for the suction and exhaust FAN. The microprocessor of the Y board reads the resistance value of the thermistor (TH2020) (resistance value changes according to the temperature) mounted on the S board and outputs the 0 to 5 V voltage from the port to Pins 7 and 9 of CN2701 of the GD board. By adding the current based on the voltage to the ADJ terminal of the regulators (IC2701 and IC2702), the suction FAN controls the 10.2 V to 6 V (FAN+B1) while the exhaust FAN controls the 10.2 V to 7 V (FAN+B2) voltage. The thermistor TH2020 mainly monitors the external temperature of the unit. When the LAMP MODE STANDARD mode is selected on the menu, both fans are set to the minimum voltage of FAN 7 V for the suction FAN and 8 V for the exhaust Fan. When the LAMP MODE LOW mode is set, the fans are set to the minimum voltage of FAN 6 V for the suction FAN and 7 V for the exhaust Fan.
