5. Powering up.
[Back to contents]
If the unit has been allowed to cool down to below 15ºC, then additional time will be needed before the unit
can be run. Ideally, the system should be stored at room temperature (20ºC) for at least 24 hours prior to
deployment.
Connect the basic modules as shown in the schematic below. Make all of the connections before switching the power
on. A time-delay device inside the Lidar prevents 'hot' power from being applied directly to the internal sub-
components.
Optional kit of parts.

*An additional fuse is fitted inside the UPS unit if the extended cooling option is fitted.
Ensure that a keyboard, mouse and monitor are connected for the first power up.
Once the UPS module has power and is connected to the Lidar, there may be a short delay before the Lidar starts up
of 10 to 15 seconds. The thermal control system has power 5 seconds or so after power is applied to the Lidar, and so
the external fans may run. Note that if the fans are running, it doesn't mean that the Lidar itself is also powered, as the
Lidar and thermal control run from separate fuses & time delay units.
Systems fitted with the Active or Extended temperature option.
If either of these options is fitted, the heat exchanger fans will be on all of the time, and soon after power is applied to
the Lidar. The cooling circuit is not covered by the UPS unit, and will go off during a power cut. If the fans are not
operating, and there is not a power cut, then the fuse F-2 may be blown. If fuse F-2 is not blown, then there may be a
fault with the cooling unit, in which case, the Lidar should be powered down to avoid the risk of it over heating.
