Chapter 11 Interface Specifications 11.4Emergency Stop (E-STOP)/ Remote Interlock (REMOTE I/L) The emergency stop signal and the remote interlock signal are assigned on the E-STOP/Remote I/L connector. To comply with the PL (Performance Level) “e” of ISO13849-1, you need to use the recommended component in the input.
11.4 Emergency Stop (E-STOP)/ Remote Interlock (REMOTE I/L) 11.4.1 Pin Layout ALL CONNECTIONS ARE POTENTIAL FREE DRY CONTACT CLOSURE ONLY. Do not apply any voltage or current or you will damage the system. ■Input Signals Pin No. Signal Description Note Emergency Stop input 1A External emergency stop 1 input (channel 1)
Chapter 11 Interface Specifications 11.4.2 Connection Examples ■Remote Interlock • After a remote interlock is canceled, turning ON error reset input will turn ON startup ready output and marking ready output. • Be sure to simultaneously turn ON/OFF the interlock 1 and 2. When either one is turned OFF (opened), a remote interlock state is not canceled.
11.4 Emergency Stop (E-STOP)/ Remote Interlock (REMOTE I/L) ■Emergency Stop ■Emergency Stop for Simple Systems Interfacing with External Emergency Stop Circuitry E-STOP button(s) ONLY The laser marker can be interfaced to a simple system including an enclosure and one or more external emergency stop buttons.

Chapter 11 Interface Specifications ■Emergency Stop for Complicated Systems Interfacing with External Emergency Stop Circuitry User Supplied Safety Relay Module(s) Required Complicated Systems are those in which more than one emergency stop sub-circuit must be linked together. An example of this would be a machine that has a laser marker, parts handler with pneumatic controls, PLC, and conveyor belt all of which have ESTOP buttons where one ESTOP button stops all devices.
11.4 Emergency Stop (E-STOP)/ Remote Interlock (REMOTE I/L) 11.4.3 Time Chart For remote interlock and emergency stop, be sure to simultaneously turn ON/OFF inputs of 2 channels (the difference between channel 1 and channel 2 should be within 250 ms). When either one is turned OFF (opened), a remote interlock or an emergency stop function, but it cannot be canceled even if the error reset is input after it is turned ON (closed) again.
Chapter 11 Interface Specifications ■Emergency Stop *3 After an emergency stop is canceled, turning ON error reset input will turn ON startup ready output. Then, turning ON laser start input will turn ON both LD ON and marking ready outputs. *4 Be sure to simultaneously turn ON/OFF the emergency stop 1 and 2.

Chapter 12 Maintenance 12.3Air Filter Inspection and Replacement Always inspect the air filter of the Control Unit starting the equipment. If it is dusty, vacuum it. Every 1 to 6 months, remove the air filter and wash it with a mild detergent. (The filter may become dirtier in some operating environments.) Dirty air filter will increase the internal temperature, which may in turn damage the equipment.

Chapter 12 Maintenance Be careful not to drop the protective glass, as it may break. Fit a new protective glass into the protective glass holder's stepped section. • The protective glass may be damaged if it is not properly fitted into the stepped section.
12.5 Fiber Laser Module Warranty Period 12.5Fiber Laser Module Warranty Period For information on warranties on units other than the fiber laser module, refer to "Warranty." When the laser power (processing power) declines and the specified laser power cannot be obtained even after increasing the current to the maximum, the fiber laser module* may need to be repaired or replaced.
Chapter 12 Maintenance 12.6Backup Lithium Battery Replacement The Control Unit includes a lithium backup battery. If this battery runs out, settings in the memory will be lost when the Main Switch of the Control Unit is turned off. To prevent this, purchase a new battery from us and replace the battery under either of the following conditions: •...
