3. Connector Functions
Input Pins of EXT.I/O (1) Connector
⇒
Supply power to pin No.16 and pin No.17 and put the section between pin No.23
and COM in a closed circuit.
Pin No. Description
14
0 V OUT
Power supply for external input signals. This pin is exclusively used for the ML-
2350A/2351A. Do not use it for any other purpose.
15
+24 V OUT
Power supply for external input signals. This pin is exclusively used for the ML-
2350A/2351A. Do not use it for any other purpose.
16
External signal source IN
Input terminal for the external signal power supply. Connect it to Pin 14 or Pin 15,
depending on the input signal circuit.
17
External signal COM
Common input terminal for external signals. Connect it to Pin 15 or Pin 14, depending
on the input signal circuit.
18
HV-ON/OFF
When this Pin 18–COM circuit is closed, the high voltage is turned ON.
When the circuit is opened, the high voltage is turned OFF.
19
TROUBLE RESET
If trouble arises, an alarm is activated. When the cause of trouble has been eliminated
and this Pin 19–COM circuit is closed, the alarm will be canceled.
20
LASER START
When Pin 21–COM circuit is closed, the laser beam is output. Make sure that the circuit
is left closed for at least the time set on the MEMORY SWITCH screen. When the signal
is input repeatedly, make sure that the circuit is left open for at least 40 ms between
each input and the repetition interval is within the maximum rated output.
21
LASER STOP
When outputting the laser using Pin 20, close this Pin 21–COM circuit.
For the repeated output for which the number of outputs is set in "REPEAT" on the
SCHEDULE screen, the laser output is stopped by closing the section between the pin
and COM during a laser output. The closed circuit time should be 1 ms or more.
22
GUIDE BEAM
While this Pin 22–COM circuit is closed, the guide beam is output.
23
CONTROL CHANGEOVER
While this Pin 23–COM circuit is closed, the external input signals are effective.
24
RESONATOR SHUTTER
When the section between this pin and the COM is closed, the resonator shutter is
opened to enable laser oscillation. When this section is opened, the resonator shutter
is closed to disable laser oscillation.
25
BEAM SELECT 1
When this Pin 25–COM circuit is closed, laser beam input unit 1 is selected and the unit
becomes ready to project a laser beam.
26
BEAM SELECT 2
When this Pin 26–COM circuit is closed, laser beam input unit 2 is selected and the unit
becomes ready to project a laser beam.
