SECTION 6: TROUBLESHOOTING AND MAINTENANCE
6.1
GENERAL
6.1.1
Level of Repair
These troubleshooting procedures will determine only if the IQ 300 Display Module
or the IQ 300 Base Module is the cause of a malfunction. They will not permit
troubleshooting of components within the IQ 300 Modules. If an IQ 300 Module is
determined to be at fault, replace it with a spare and return the malfunctioning
Module to Cutler-Hammer for repair.
6.1.2
Maintenance and Care
The IQ 300 is designed to be a self-contained and maintenance-free unit. The
printed circuit boards are calibrated and conformally coated at the factory. They are
intended to be serviced by factory trained personnel only.
Never
clean the IQ 300 with system or power on. Clean the IQ 300 using only a
clean, dry cloth. Do not use water or solvents of any kind.
Operate the IQ 300 Base Module in an environment within the temperature range of
-20°C to 50°C and the IQ 300 Display Module within a range of 0°C to 50°C. The
environment should also be free of excess humidity.
If you have spare units, store them in the original packing material and container.
The base unit storage environment temperature range should be -30°C to 85°C and
-20°C to 60°C for the display module.
