Details of the signals

1. CTRON signal and KCTRON signal (output signals)
These signals are synchronized with electronic counter of the equipment and they become "Low"
when one sheet of paper is counted up. They are the signals for the coin controller and key counter,
and output from the LGC board. Since MP6H1 or 2SC5712 is used as the driver, the mechanical
counter can be driven directly.
Only with the KCTRON signal, the counter will make "Double count" if 08-6010 (count setting of
large size paper) is set to "1" or "2".

2. CTRCNT signal and KCTRC signal (input signals)
The CTRCNT signal enables to accept copies when the coin controller is connected, and copies can
be accepted with "Low". In case of "High", "Set Key Counter" appears and copies cannot be made.
The KCTRC signal enables to accept copies when the key counter is connected, and copies can be
accepted with "Low". In case of "High", "Set Key Counter" appears and copies cannot be made.
3. MCRUN signal (output signal)
The MCRUN signal is changed to "Low" during copying. It becomes "Low" at specified time or more
before the CTRON signal becomes ON, and becomes "High" at specified time or more after the
EXTCTR signal becomes OFF.
However, if copying is interrupted due to forced toner supply or similar, this signal is "High" until the
copying is available.
This is the signal for the coin controller.
