Failure Display
SWING
When there is failure in the unit operation, “ERROR” will flash on
the LCD of the wire controller and the code of failure will also be
displayed. When there are multiple failures at the same time, the codes
of failures will be displayed one after one on the wire controller. The
first digit of the code denotes the system number. When there is only
one system, it will display the system number 1. The last two digits
denote the detailed failure code. For example, the code in left means
low pressure protection of compressor.
