SAFETY_CYL
I
REG 12V short detection signal.
It is a measure for cylinder driver over heat by short.
Perform detection process at 3 seconds after that the P.ON (H) signal at Pin 4 of IC6001
has been shifted from Low to High.
[Detection method]
When the terminal voltage is less than 3.0V during 3 seconds continuously, the power is
turned off compulsorily.
* When a cassette is in, the power is turned off after a few second delay for the
mechanism initial function.
* Key/Remote controller input is inhibited while the compulsory power off process.
