operator’s manual

Integrating Firestar safety features

Your control system can monitor the laser’s shutter status on the

User I/O

connector by connecting your

system’s input to Pin 14,

Shutter Open

, and Pin 13,

Output Common

(see Figure 3-16). The

Shutter

Open

output closes when a

Shutter Open Request

signal is present (

SHT

LED illuminated blue) and the

Laser Ready

output is closed (

RDY

LED is On). The output is open (

SHT

LED Off) when the

Shutter

Open Request

signal is removed or the

Laser Ready

output is open (

RDY

LED is Off).

Remote interlock functions

Interlock circuits are often used to disable machinery when a shield, panel, or door is opened. Firestar’s re-
mote interlock function allows you to connect into an external remote interlock circuit and prevent lasing
by removing DC power from the laser’s RF driver boards when the circuit is electrically “open”.

Lasing is enabled when a

Remote Interlock

signal is present (

INT

LED illuminated green), if the

RDY

LED is illuminated and a

Shutter Open Request

signal is applied. Lasing is disabled when the

Remote

Interlock

signal is removed (

INT

LED red,

RDY

LED off). DC power is applied to the RF driver only when

the

INT

LED is green and the

RDY

LED is yellow. Remote interlock functionality is provided by the

Re-

mote Interlock

signal via Pin 3 on the

User I/O

connector.

To use Firestar’s remote interlock feature to initiate lasing, apply a voltage in the range of ±5–24 VDC to
Pin 3,

Remote Interlock

. Applying a

Remote Interlock

signal causes the

INT

LED to turn green, the

RDY

indicator to turn yellow, and sends DC power to the laser’s RF boards. After a five-second delay, a tickle
signal is applied to the tube. When a

Shutter Open Request

signal is present, PWM Command signals

are enabled to begin lasing. Removing voltage stops DC power from reaching the RF driver, causing the

INT

LED to turn red and the

RDY

LED to turn Off. Lasing remains disabled until a voltage is reapplied to

Pin 3.

Your control system can monitor the laser’s remote interlock status on the

User I/O

connector by connect-

ing your system’s input to Pin 15,

Interlock Open

, and Pin 13,

Output Common

(see Figure 3-16). This

output is closed when remote interlock circuitry is open (

INT

LED illuminated red). The output is open

(

INT

LED green) when interlock circuitry is closed.
