Signal strength LED status
LED status Description Actions
Solid red Beam break - measurements cannot be made,
• Check laser beam is present
• If no laser beam, power cycle
• If issue persists, contact local Renishaw office
Solid amber
Beam low - measurement accuracy is reduced,
danger of beam break occuring
• Check laser alignment
• If measuring separation > 40 m use high gain mode
• If issue persists, contact local Renishaw office
Single green LED
indicates minimum
beam strength,
increasing up to 5 green
LEDs for maximum
beam strength.
Signal strength OK. Open Capture in XL mode
Beam strength LEDs
At the front of the top panel of the XL laser there are 5 LEDs. These have a dual
function:
1. Preheat mode:
When the XL laser is first switched on and is undergoing preheat, the
beam strength LEDs will initially all turn amber. As the preheat sequence
progresses, the LEDs will go out in turn, indicating how far through the
sequence the laser has progressed. When the final amber LED goes out
the LEDs will then switch to ‘beam strength’ mode.
2. Beam strength mode:
When the laser is switched on and has stabilised, the 5 LEDs indicate the
returned beam strength i.e. the level of interference between reference and
measurement laser beams returned from the external optics. This provides an
indication of how well the laser and optics are aligned, as shown in the table
above. These LEDs are in addition to the beam strength indication in system
software, but are helpful when working away from the computer screen.
Note: When there is sufficient signal strength to maintain a single green
LED, the system accuracy is independent of signal strength.
