DIAGNOSTIC DISPLA
Y
Note:
Because the pressure s
witches are monitored only when "Y1" (Input) is activ
e
, the
code f
or pressure s
witch open will not be seen when "Y1" is off
.
Instead, the
“Nor
mal Oper
ation" or
“Anti-Shor
t Cycle Loc
k
out”
code will be seen.
When a pressure s
witch opens and causes a shor
t cycle loc
k
out, the pressure s
witch-open
code will be seen until it closes
, then the shor
t cycle loc
k
out code will flash unless it has
already e
xpired.
