DESCRIPTION OF STATUS ALARM
Working status indication (LED) is near the powers supply switch in the front panel.
When it is green, the device is working properly; when it is red, the laser does not
work; when it is red blinking, there is an alarm.
A.
With 120V power supply, if the EDFA is functioning properly, the digital panel
will display “READY: KEY OFF” and there is Red light.
B.
Turn on with the key, the digital panel will display “KEY OFF”. After a few
seconds, the laser is turned on automatically and the indication light turns
into Green from Red.
C.
Pressing the

keys will allow you to display the operating parameters .
D.
If any fault listed above has occurred, there will be an alarm (Red blinking
LED), the Microprocessor will shut down the laser automatically, and digital
panel will show the reason of the fault.
E.
In order to protect the laser, the power supply of the laser has a time-delay
function. After turning on the keyswitch, the laser will start to work after a 10
second delay.

OPERATION NOTICE
1.
The machine should have good grounding with grounding resistance<4
Ω
.
2.
The machine adopts high performance, high reliability, and steady voltage
switch power supply. It has constant voltage overflow protection and can work
in 120 VAC electric network. The micro-processor can monitor the output DC
voltage. If the Fuse is melted broken, it will show that the machine’s inner
parts has occurred problems.
3.
In order to make sure reflection loss is ≥45dB, we use SC/APC connector;
other type (such as FC/PC, SC/PC, or ST/PC) have insufficient reflectivity. Keep
the connector clean when installing, and after several plug-in/outs, clean it
with a greaseless cotton cloth and anhydrous alcohol.
4.
Do not turn on the machine without the fiber output connected or without a
protective cover at the connector end. Otherwise the laser could do harm to
the human body, especially the eyes.
