Required by:
Feature Location/Description CDRH EN60825-1
Keyswitch
1
Panel control Yes Yes
On/Off Keyswitch controls power to laser electronics. Key can not
be removed from switch in the “On” position.
Shutter Laser control Yes Yes
function
1
Attenuates beam / disables RF driver/laser output when closed.
Power
2
Panel indicator (Green) Yes No
indicator Indicates that laser has power applied and is capable of lasing.
Lase Panel indicator (Red) Yes Yes
indicator Indicates laser is actively lasing. Illuminates when duty cycle of
Command signal is long enough to produce laser output.
Five-second Circuit element Yes No
delay Disables RF driver/laser output for five to ten seconds after Key-
switch is turned to “On” and remote keyswitch is closed.
Power-on Circuit element Yes No
reset Disables RF driver/laser output if input power is removed then later
reapplied (AC power failure) while Keyswitch is in “On” position.
Remote Panel connection Yes Yes
Interlock
1
Disables RF driver/laser output when remote interlock switch on
equipment door or panel is opened.
Remote Panel connection No No
Keyswitch Allows operator to turn laser On/Off from a remote location.
Over/under Circuit element No No
voltage Fault shutdown occurs if supply voltage falls below +15 V or rises
protection above +36 V. Reset laser to restore operation.
Reverse Circuit element No No
voltage Internal diode protects circuitry from reverse input voltages.
protection External fuse will blow.
Overtemp Circuit element No No
protection Over temperature shutdown occurs when temperature of tube
reaches 60 °C ±2 °C. Reset laser to restore operation.
PWM failure Circuit element No No
protection Disables laser if output power exceeds Command input by 20%
or more due to electronics failure. Reset laser to restore operation.
Fault signal Signal output No No
Latches to a logic low state when a fault shutdown occurs.
Message Signal output No No
signal Pre-shutdown warning latches to a logic low state when tube
temperature reaches 54 °C ±2 °C.
Warning Exterior housing Yes Yes
labels Labels attached to various locations to warn of potential hazards.
