Status LEDs
Section 2 includes chapters on using CONTROL and how to manage and operate the
system and any inserted modules.
Status LEDs
The front panel houses three status LEDs as described in Table 1 . The LEDs are
located on the front panel as shown in Figure 3 .
Table 1 Status LEDs
LED Name Condition Description
Power ON Green AC mains connected and the system power switch is in the
ON position.
ON Red Fault with the DC power supply
NOTE : When the system is switched ON or OFF the LED will
momentarily flash red – this is NOT a fault.
OFF System switched OFF or no AC mains power
Status OFF One of the following:
•
Interlock is reset but there is no emission from the
system
•
Alternatively, firmware is being uploaded to the
system main control board. During firmware upgrade,
the interlock cannot be reset and no emission from the
system is possible.
ON Amber Interlock requires a reset – cycle the key switch from the
OFF to the ON position.
Flashing Amber The system main control board is scanning for modules
inserted into the system and accessories connected to the
external bus.
ON Green Laser emission enabled and stable on all inserted modules.
Flashing Green Laser emission enabled from inserted modules but at least
one module has not stabilized.
ON Red One of the following:
•
Either one or multiple sub-modules inserted in the
system have autonomously shutdown. Other modules/
channels will continue to operate, i.e. they will not be
shutdown by the system control section.
•
The system control section has shutdown all modules/
channels.
•
BOOSTIK emission failed to turn ON emission due to
no input power.
•
Interlock circuit opened during emission.
In the first three cases above use CONTROL to check for an
actual error code. If the interlock circuit opened, check the
key switch position and interlock circuit continuity.
Flashing Red Firmware is being uploaded to modules in the Koheras
ACOUSTIK system or accessories connected to the External
Bus.
Emission ON Red Laser module emission is ON.
OFF Laser emission is OFF.
