ADJUSTMENT AND CONFIRMATION PROCEDURES 3
Confirmation of fan operation
1. Set the unit to Test-1-00.
2. Apply the signal 1kHz, -15dBV to the MULTI CH. terminal input with no load.
Confirm that the fan rotates slow after few seconds.
Confirm the all channels except SUBWOFFER.
3. When connect the resistor 1.2 kohm/1 W between
the terminals 24V and TH1L of P6401, confirm that
the fan rotates slow speed after few seconds.
4. When connect the resistor 1.2 kohm/1 W between
the terminals 24V and TH1L of P6401 and connect
the resistor 1.2 kohm/1 W between
the terminals 24V and TH2L of P6402, confirm that
the fan rotates fast speed after few seconds.
5. When connect the resistor 1.2 kohm/1 W between
the terminals 24V and TH1R of P6401 and connect
the resistor 1.2 kohm/1 W between
the terminals 24V and TH2R of P6402, confirm that
the fan rotates fast speed after few seconds.
Confirmation of voltage sensor and thermal protect
1. Set the unit to Test-3-02.
2. Apply the signal 1kHz, -15dBV to the MULTI CH. terminal input with no load.
Confirm that "FM Stereo" indicator lights on.
Confirm that the all channels except SUBWOFFER.
3. When connect the resistor 1.2 kohm/1 W between
the terminals 24V and TH1L of P6401, confirm that
"MEMORY" indicator lights on.
4. When connect the resistor 1.2 kohm/1 W between
the terminals 24V and TH1L of P6401 and connect
the resistor 1.2 kohm/1 W between
the terminals 24V and TH2L of P6402, confirm that
the fan rotates fast speed after few seconds.
5. When connect the resistor 1.2 kohm/1 W between
the terminals 24V and TH1R of P6401 and connect
the resistor 1.2 kohm/1 W between
the terminals 24V and TH2R of P6402, confirm that
the fan rotates fast speed after few seconds.
