If it is antenna tuning network impedance is 50 ω +JX, adjusts the impedance of antenna tuning network; if your network is the transmitter output impedance deviation falls high voltage shutdown. Turn the machine outputs on the right network behind the back panel of the chassis. Adjust the transmitter output L102 in band-pass filter inductance in the network. Power amplifier for adjusting an inductance turned on watching a current amplifier current of 50A.DEGservice manual download site

When the amplifier when the currents of 50A. Incoming power is 10kW. Let machines to maintain this State work for 10-15 minutes and falling hands-high voltage Shutdown check 42 stages and 6 small steps of power amplifier modules "temperature of WD" is normal.DEGservice manual download site

If the "temperature of WD" normal, then opened the controller board (ILA/HG3.624.009LD) modulated digital signal on the switch s is ON state, restoration of digital modulation and coding (ILA/HG2.871.010DL) digital loop on the encoding switch s is ON status. Power plus high pressure, use multimeter to measure output of digitally controlled potentiometers TP7 (ILA/HG2.886.000DL analog input Board) should have about -0.5VDC DC, or measuring N4-7 (NE5532N) X6-lO (analog input Board) at the DC component should be around -3VDC. This voltage change with ascending or descending power button changes. Shutdown recovery audio signal input, power on the high pressure on incident power is 10kW, amplifier current with digital audio modulation signal amplitude changes in size at around 50A.DEGservice manual download site

Because digital audio processing system of the output signal is "audio + DC", the audio component determines the modulation depth of the transmitter. DC controls the size of the transmitter output power. If people misuse the incident rise to the 12~13kW of the transmitter the machine working properly. However, long-term jobs in this state of high power, also will increase the burden of the PA amplifier, amp current must rise. In order to avoid this phenomenon, to disconnect the transmitter audio input, power on the high voltage with a small screwdriver to adjust the analog input Board (ILA/HG2.886.000DL) maximum power adjustment potentiometer on the R27, set the lock machine maximum input power is 10.5KW. When the lock is finished, press the power key, input power up to 10.5kW maximum values won't rise, so as to effectively control the phenomenon caused by the improper use of high power and high current production.
