User I/O connections
Output signals
Firestar’s ve user outputs correspond to the status functions described below. Outputs are optoisolated,
bi-directional analog switches that allow for high-side or low-side switching. The shared connection,
Output Common, is separate from the laser’s chassis ground to allow high-side or low-side switching and
to isolate control signals for optimum EMI performance.
Firestar’s optically-isolated outputs are useful for sending laser status to a Programmable Logic Controller
(PLC) or computerized control system. Each of the ve outputs can source 50 mA at ±24 VDC maximum
for a total load of 250 mA. For controlling larger loads, use these outputs to drive a control relay.
Note: Laser Ready and Shutter Open outputs denote separate control functions. The Laser Ready
output (Ready LED On) may close while the Shutter Open output is open (Shutter LED O), but
the RF driver is disabled until both Laser Ready and Shutter Open outputs are closed (Ready
and Shutter indicators illuminated).
Pin 6 Laser Active
This bi-directional switched output is internally connected to Pin 13, Output Common, when
the laser is actively lasing (Lase indicator red). This output is open (high impedance) when no
beam is being emitted (Lase indicator O). Refer to Table 3-5 for output circuit specications.
Pin 7 Over Temperature
This bi-directional switched output is internally connected to Pin 13, Output Common, when
laser temperature is above safe operating limits (Temp indicator red). The output is open (high
impedance) when laser temperature is within operating limits (Temp LED green). After an over
temperature fault occurs, cool the laser and then cycle DC power to reset the laser. Refer to Table
3-5 for output circuit specications.
Pin 8 Laser Ready
This bi-directional switched output is internally connected to Pin 13, Output Common, when
the laser is enabled (Ready indicator On), indicating that lasing will occur when a PWM Com-
mand signal is applied to Pin 9 and Pin 1. When this output is initially switched closed, there is
a ve-second delay during which lasing is inhibited. This output is open (high impedance) when
the laser is disabled (Ready LED O ). Refer to Table 3-5 for output circuit specications.
Pin 13 Output Common
Use this pin to complete the return (ground) path for any output connection (Pin 6, 7, 8, 14, or
15). The Output Common line is protected by a 0.25 A self-resetting fuse.
Pin 14 Shutter Open
This bi-directional switched output is internally connected to Pin 13, Output Common, when
the Shutter Switch is Open and a Shutter Open Request signal is present (Shutter LED blue),
indicating that lasing may be enabled if other operating conditions are met. The output is open
(high impedance) when the Shutter Switch is Closed or the Shutter Open Request signal is
removed. When Shutter Open output closes (Shutter LED O), there is a ve-second delay until
PWM inputs are recognized. Refer to Table 3-5 for output circuit specications.
Pin 15 Interlock Open
This bi-directional switched output is internally connected to Pin 13, Output Common, when
remote interlock input circuitry is open (Remote Interlock LED red), indicating that lasing is dis-
abled. This output is open (high impedance) when the laser is enabled (Remote Interlock indicator
green). When this output is initially switched open, there is a ve-second delay during which
lasing is inhibited. See Table 3-5 for output circuit specications.
