Tm0/Tm1/Tm2; Fan Drive Test - Yamaha RX-Z9 Service Manual

TM0/TM1/TM2

This is the A/D value of the heat sink temperature detect
ports THM0, THM1, and THM2 (main microprocessors).
TM0 (THM0): Detects the temperature of heat sink L.
(Normal value: 5 to 24)
TM1 (THM2): Detects the temperature of heat sink R.
(Normal value: 5 to 24)
TM2 (THM2): Detects the temperature of the regulator heat
sink.
(Normal value: 5 to 24)
When the value is outside of the normal range, the protec-
tion function works to turn off the power.

K0/K1
This is the A/D value of the panel key input ports KEY0 and
KEY1 (main microprocessors of the main unit). The table
below shows the A/D value obtained when each key is
pressed. When the value is not within the standard value
range, no correct operation is provided. Referring to the table
below, check the value of each voltage dividing resistor of
each key, solder condition, etc.
The keys of the main unit are
different between DXP-Z9
and RX-Z9 (with/without
TUNER) but keys of the
same function have the
same AD value.
The "PURE DIRECT" key is
not detected by the AD func-
tion.
