MAINTENANCE AND TROUBLESHOOTING
There are no operator-serviceable components inside the CG1000 system.
An operator should never remove the cover from the controller or sensor.
System and Error Messages
System and error messages appear on the fourth line of the display at
three-second intervals until the condition is corrected or has ended. If
there is more than one message, the messages will alternate on the display
at three-second intervals. These system and error messages are listed in
this appendix alphabetically.
NOTE
The operations in this chapter should be performed only by qualified
service personnel with a knowledge of electrical safety techniques.
Never service the controller or sensor unless power has been discon-
nected from the controller and the sensor, and the sensor has been al-
lowed to cool for at least one hour. Always wear gloves when working
on sensor components.
System or error messages will not appear on the display when you are
using the control unit keys to access menu functions.
