8.3 Trouble-shooting
The CS200 monitors all input signals, running conditions, and external feedback information. Once a fault occurs,
the AC drive performs protection and meanwhile the operation panel displays the fault code.
The ve-digit LED data display is numbered 5, 4, 3, 2, 1 from left to the right, amongst which 5# indicates the fault
level, 4# and 3# indicate the fault code, and 2# and 1# indicate the fault sub-code and are reserved. For example,
the display is 103.02 as shown in the following gure.

Before contacting Inovance for technical support, you can rst determine the fault type, analyze the causes, and
perform troubleshooting according to the following tables.
The CS200 is the core of the entire electrical control system of the elevator construction. The fault information of
the CS200 is classied into ve levels. The AC drive performs different actions for different fault levels, as listed in
the following table.
