3. Connector Functions
Output Pins of EXT.I/O (1) Connector
Pin No. Description
1
Ready
When the high voltage is turned ON and the capacitor is fully charged, this Pin 1–COM
circuit is closed internally.
2
High Voltage ON
While the high voltage is supplied, this Pin 2–COM circuit is closed internally.
3
Trouble
If trouble arises, this Pin 3–COM circuit is opened internally until it is reset.
4
End
After the lamp has ashed, this Pin 4–COM circuit is closed internally for 50 ms.
5
Monitor normal
When the monitor value of laser energy is in the range of "HIGH" and "LOW" set on the
POWER MONITOR screen, the circuit is closed for 50 ms.
6
Monitor trouble
When the monitor value of laser energy is out of the range of "HIGH" and "LOW" set on
the POWER MONITOR screen, the circuit is closed for 50 ms.
7
Unused
Do not connect anything.
8
External input receivable
When an external input signal is acceptable (when the section between pin No.23 and
COM is in a closed circuit), the circuit is closed. In the open circuit status, an external
input signal is not acceptable if it is input.
9
Lamp power upper limit
When the lamp input power exceeds the value set in "REFERENCE SET", the circuit is
opened.
10
Unused
Do not connect anything.
11
Unused
Do not connect anything.
Type of output: Photo MOS relay output
Rating of output: 24 V DC, 20 mA max.
