4. Its Fail Safe High or Low will return the output to 3 psig for Direct Acting Mode or to 15 psig for Reverse Acting Mode if the power is lost, regardless of the logic selected.
5. When the tank pressure reaches 305 psig, a mechanical air-cooled refrigeration unit is activated which cools the tank contents and thereby reduces the pressure to about 295 psig.
6. Its Fail safe High or Low will return the field reversible output to 3 psig for Direct Acting Mode or to 15 psig for Reverse Acting Mode if the power is lost, regardless of the logic selected.
7. Its Fail safe High or Low will return the field reversible output to 3 psig for Direct Acting Mode or to 15 psig for Reverse Acting Mode if the power is lost, regardless of the logic selected.
