1) Fuse alarm signal (FAL1, FAL2)
The warning signals contact of the thermal switch and circuit
protector. When the contact is closed, turn off either the CNC
power supply or the laser power supply ON/OFF signal. Contact
capacity 220 VAC, 6A or 24VDC, 10A.
2) OFF prohibition signal (OFS1, OFS2)
Closing the contact to inhibit the OFF switch operation. Connect
in parallel with the OFF switch. Contact capacity 250VAC, 3A or
30 VDC, 5A.
3) Laser power unit ON/OFF signal (ON, OFF)
When the door interlock is used.
Connect 200VAC whose ON/OFF is controlled by CNC
Capacity 200 VAC, 10mA
4) Door interlock contact signal (ND11, ND12)
B contact (AC200V applied to laser and CNC is shut in OPEN
state.)
Use the key switch with the compulsion dissociation mechanism
for the key switch used for welding prevention. When the door of
the oscillator is open, the contact opens. When the contact is open,
the ON–OFF signal of 200 VAC, 3A or 30 VDC, 5A.
