POWER FAILURE CIRCUIT

Check the following if the unit is turned off by the power
failure detector.

1. Disconnect the AC power cord (120V AC line) for a short

time.

2. Connect a DC Voltmeter to the circuits shown below.

3. Press the Power key and check for the proper voltage

supplies.

4. If any of these voltages is low, the power failure detec-

tor should turn the unit off within three seconds.

5. Check all circuits shown below.

Note

: If power failure is detected 3 times in 15 minutes,

the set will enter the standby mode and cannot be
switched On.To reset the operating programs of the
CPU it is necessary to disconnect the AC cord for a
short time.

CPU (IC800) is programmed so the set will go to standby
mode when there is circuit failure as described below.
(Refer to“Block Diagram Power Lines”.)

This unit is equipped with a Power Failure Detector function
included in the CPU which checks for an abnormal condi-
tion in the chassis power supplies.

If, while the power is on, a failure is caused by any of the
following that results in a low voltage supply, the CPU will
turn the unit off in 1.5 seconds to prevent further damage:

•

Failure within the power supply circuits.

•

A short circuit in the load side from the supply.

Power Failure:

Detected voltage failure for circuit.

(Connected to IC800 pin 32 and pin 23.)

(Normal: High; Failure: Low)

If, while the power is off, the power is switched on and any
of these failures remains uncorrected, the CPU will shut off
the power within three seconds.
