I have a system that ive been working on its a large R22 condensing unit with 2 semi hermetic compressors. It has automatic pumpdown on it, and ive been noticing the compressors cycling on and off ALOT. sometimes every minute or two.

What exactly is the automatic pumpdown for? and why is it doing this cycling so often?

i shut the automatic pump down switch off for now so the compressors dont get destroyed from going on and off so often, They are pretty large semi hermetic compressors.
