OCP

Low B and +B line detect DET SHORT, and shut-down POWER ON RELAY.

Reset by turning power on/off.

In case of +B is loaded approx. 1.5A or more, microcomputer detects it via IC6102.

OVP

In case of +B becomes approx. 150V or more, POWER ON RELAY shuts down and microcomputer detects it via IC6102.

Reset by turning power on/off just the same as OCP.

V Stop

In case of V Drive disappeared, Q5005 detecs it and shut-down POWER ON RELAY. Microcomputer detects it and makes LED

blinking.

AKB

IK detection.  Makes LED blinking in case of microcomputer doesn’t detect IK returns of IC511  (CXA2101AQ) 30 seconds or

more.

H Stop

In case of H DRIVE is disappeared, Q5006 detects it and shut-down POWER ON RELAY shuts down.

Microcomputer receives H Stop data from Q5006 and makes LED blinking.

HV Stop In case of HV becomes 33KV or more. IC8006 and IC8010 detect it and shut-down

POWER ON RELAY. Microcomputer makes LED blinking.

Audio

In case of DC component overlaps the output of Audio Amp., POWER ON RELAY shuts down.

Microcomputer detects it and makes LED blinking.
