Use of an oil safety switch is recommended/required by
Carlyle as noted in the chart below:
Electronic Oil Pressure Safety Switch
See Bulletin 11T-2 at www.carlylecompressor.com
Description:
The new Carlyle Oil Pressure Safety Switch (OPSS) is an
enhanced means for protecting the compressor from loss of
lubrication. The new Carlyle OPSS is an upgrade to the
Danfoss MP54 and Penn P545 and will protect the compres-
sor from damage due to low oil differential pressure in recip
compressors with oil pump lubrication. The lack/loss of
lubrication will result in serious damage of compressor bear-
ings and sliding surfaces.
