Issue:
Low oil flow?
Resolution:
The 70-125 ton RTXX chiller platform does NOT use an oil DP switch.
Verify the correct compressor model number is selected in Service Settings \ Machine Configuration..., this should be CHHN for these chillers.
RTAA 70-125 TON, RTWA 70-125 TON, RTUA 70-125 TON chillers.
On the compressor module for each circuit, verify there is a good electrical connection on the jumper wired between J3-1 to J3-2. See example below of Circuit 2 (1U5) DP Switch Input Jumper.
