Failure Display
When there is failure in the unit operation, “ERROR” will
flash on the LCD of the wire controller and the code of fai-
lure 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, the system number is not displayed. The last two
digits denote the detailed failure code. For example, the
code in

pressor.
