KL SERIES: MANUAL LIGHT TOWER LOWERING


When a Knight Series light tower fails to rotate (or does not want to auto park because the tower is off-center), this Technical Video shows technicians how to replace the rotation motor on a Knight Series light tower.


MAINTENANCE/TROUBLESHOOTING



KL SERIES: AUTO-PARK OVERVIEW/TROUBLESHOOTING


This Technical Support video overviews the KL Series’ normal auto-park sequence and shows technicians how to set the tower’s center (through sensor adjustment) and how to eliminate light tree sway (through motor belt adjustment) when the tower fails to auto park.



KL SERIES: ROTATION MOTOR BELT ADJUSTMENT


During routine light tower maintenance or when you need to troubleshoot an off-center tower that is failing to auto park, please reference this video. This video further demonstrates how to tighten the rotation belt to reduce to side-to-side lamp movement.



KL SERIES: NEST SWITCH REPLACEMENT


In tandem with the first two videos in this section, this video shows technicians how to replace the nest switch in a KL Series light tower when it has issues auto-park nesting. (A nest switch provides essential relays when the tower is performing its auto-park sequence.)



KL SERIES: DOWN-LIMIT MERCURY SENSOR ADJUSTMENT


The Mercury sensor controls the tower’s down-limit, which keeps the tower from crashing into itself or the light tower tub as it auto-parks. If you would like to adjust this limit or troubleshoot this auto-park feature, this step-by-step video shows technicians how to adjust this sensor.



KL SERIES: DOWN-LIMIT MERCURY SENSOR REPLACEMENT


If the lower section of your lamp tree hits center but does not come down during the auto-park sequence, you may need to replace the down-limit Mercury sensor. This Technical Video provides step-by-step replacement instructions for this switch.



KL SERIES: BACKLIGHT BELT ADJUSTMENT


Over time, the light tower’s belts may loosen and need adjustment. If your lamp heads seem loose, or the heads fail to return home in the auto-park sequence, you may need to tighten your backlight belt. This Technical Video provides step-by-step instructions.



KL SERIES: BACKLIGHT BELT ADJUSTMENT


Over time, the light tower’s belts may loosen and need adjustment. If your lamp heads seem loose, or the heads fail to return home in the auto-park sequence, you may need to tighten your backlight belt. This Technical Video provides step-by-step instructions.



KL SERIES: LOWER ACTUATOR REPLACEMENT


If your lower actuator fails to raise or lower the KL Series’ lower arm, first check that the actuator is receiving voltage. If the actuator is getting power, you may need to replace the lower actuator using these step-by-step video instructions.


BULB/FIXTURE REPLACEMENT



KL SERIES: STROBE BULB REPLACEMENT


This Technical Video provides a step-by-step demonstration, showing you how to replace a FRC Spectra fixture on a CL Series light tower. (Note: These replacement steps are for the CL Series and do not apply to the KL or SL towers.)



KL SERIES: COMPLETE STROBE REPLACEMENT


If your strobe isn’t working and you’ve replaced the bulb and performed the necessary voltage tests, you may need to replace the strobe. This Technical Video shows technicians step-by-step replacement instructions for the KL Series light tower.



KL SERIES: LUMENFORM BULB REPLACEMENT


This Technical Video shows technicians how to replace the bulb in a KL Series KL435, KL450 and KL465, should the Lumenform bulb go out. (Before ordering the replacement bulb, a quick voltage test will ensure the bulb is receiving power and has indeed expired.)
