Handling Precautions o Since the heat sink and transistor metallic parts are con- nected to the Front Amp output, make sure they do not contact the GND (chassis) or other ci

31、rcuits. o Since there is residual high voltage in the Power Amp Module Assy +31 (FRONT ASSY FOR 100W) and +B2 (REAR, PWR, PRTEC ASSY) even when the power is OFF, caution should be exercised. (If necessary, the voltage should be discharged). a When handling the Power Amp Module Assy, make sure you do

32、 not touch the fan motor blade. I Front Amp Side (FRONT ASSY FOR 1OOW) 2. Adjustment and Confirmation of ldle Current o Basically, the idle crurent needs to be confirmed when replacing a power transistor, driver transistor, or bias transistor, or when the entire split board Assy of the Power Amp Mod

33、ule Assy has been replaced. o Make sure the heat sink has cooled sufficiently before measuring the idle current. (Temperature should be the same as room temperature; 25oC is ideal, if possible.) o Idle current stipulated value: 3-50mA. Fig. 1 -3 Adjustment Points itepMeasurementItem Remarks I Lch si

Adjusting the Operating Temperature Setting This adjustment is necessary when IC7403 (+12V regulator), Q7301 and Q7302 (temperature sensors), or VR7701 has been replaced, or when the entire split board Assy of the Power A

44、mp Module Assy has been replaced. I Adjustment-Related Cautions a Make sure the heat sink has sufficiently cooled (is the same as room temperature Ta.) a Once the power has been turned ON, make measurements and adjustments as quickly as possible, (If too much time is taken, the heat sink temperature

45、 will rise, and the measurements will deviate from the Ta measurement point.) I Adiustment 1. Connect a voltmeter between TEMP and TP (or between IC7702 terminals No.3 and 2). (Refer to Figs. 2 3 and 2-6.) 2. Determine the fan motor operating temperature setting by means of the following formula. (T

46、olerance is within t30mV.) Formula: (85oC - Ta) x 19 (mV) Ta: ambient lemprature (C) 3. Adjust VR7701 so that the voltage between TEMP and TP is the value obtained from the above Iormula. For examole: when the room temperature is 25oC, set value : 185 - 25) x 19 mV = 1140mV tolerance within t3OmV).
