Operation of Unit
1. Mount the laser in a manner such that the beam will strike a target capable of absorbing
up to 180 Watts of power. Make sure that the airflow openings are clear of any
obstructions.
2. Confirm that the signal connections to the laser are secure and tight. Make sure that
the power supply is correctly adjusted and is capable of delivering a minimum of the
rated amps plus 2 amps margin.
3. Connect the laser power leads to DC, Red + using at least 10-gauge wire. The power
supply can affect laser performance! Use a high-quality, well-regulated supply.
4. Power up the DC supply. The fans should start.
(The “F” fan option, when programed,
will not start the fans until the laser reaches a preset temperature.)
5. Make sure the "INTERLOCK" switch is down or off, or the interlock line is ungrounded.
6. The Key Switch line must be toggled from off to on to arm the laser. If the switch is
closed when power is applied, turn it off and then on. There will be a 6 second delay
before the green "READY" light lights up.
(This switch must be toggled to arm the
system after power up.) NOTE: This function depends on the software version
and programing. OEM lasers are shipped without this function.
7. When the system arms to "READY", if the tickle is being applied, the "LASE" light
should also light up when the interlock is enabled. The "LASE" light will get brighter as
the power increases; this is normal.
8. The
“Mod Hi” connection to the laser requires that the command signal contain a tickle
pulse of 1 to 3
S at 5,000 Hz when the laser is not being commanded to fire. Tickle
rates of greater than 5,000 Hz will result in dangerous conditions (possible unexpected
low level emissions). When the laser is being commanded, the modulation rate can
reach up to 200 KHz.
NOTE: OEM lasers may be shipped with the tickle function
disabled. In this case, the user must provide the correct tickle protocol at all
times.
9. Make sure there is enough cool air available to dump the heat! Do not obstruct the air
flow in any way or modify the fans. The laser should not be near heaters or other heat
sources that increase the ambient fan inlet temperature.
