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.
