CBX
Sensor lenses.
Visual check of the lenses. Clean with Cerlic (CSC) sensor cleaning liquid and use a soft
rag if necessary. Check for build up or “film” on lenses.
Fan
Air filter, remove the cover from the outside and check the filter. The air filter might
need to be replaced or cleaned if the equipment is installed in a dusty environment.
Remove the protective grating by popping it off with a screwdriver and put it back on by
pressing it with your hand. Make sure the fan starts every time when the sensor is on
the way up. Be aware of condensation inside the CBX which can cause problems.
Screws and nuts
Verify that everything is properly secured, no loose parts or rattling
Sensor check
The sensor is easily checked by immersion in clean water. This should give a low value
of about 0 ppm . By putting something solid (a finger) in the gap a value of 3000 -‐ 9999
depending on calibration, should be given.
Troubleshooting
If external power surges, or any other problems, have caused the electronics to stop,
then a reset may be performed by switching the power OFF and then ON. This can easily
be done by opening the CBX door and then closing.
Alarm
A number of errors can be detected and shown on the BB1/BB2. The alarm error is
displayed in plain text and the alarm contact is closed. It may stop the operations of the
CBX and it is reset by pressing ENTER on the BB1/BB2.
SENSOR TILT means that the sensor has tilted more than 45 degrees and the tilt switch
in the sensor has detected this. The sensor is retracted to home position and an alarm is
shown.
SENSOR ERROR means that no signals are being received from the sensor. The sensor is
retracted to home position and an alarm is given.
SENSOR STOPPED means that the drum with sensor and cable is standing still when it
should be moving. The control stops and an alarm is given.
Appendix 1, Mounting of CBX support Stand
The support consists of two brackets, left and right hand, and a crossbar brace.
Assemble the parts according to the figure.
Hang the assembly on the handrail with the 1 ½” u-‐bolts or special L brackets for 4” or
6” handrails with supplied set screws. There are two leveling screws to adjust the stand
to hang horizontal/vertical.
