Keywords: Fermentation, Anaerobic, Aerobic


Operation

Control can be performed from either the primary control unit, or an attached PC

Troubleshooting

Problem Symptom (s) Fundamental Cause (s) Solution(s)
Drifting pH probe Hard to get a steady reading upon calibration Air bubbles may prevent contact between the the half cell and probe fluid Check for bubbles at the tip of the probe. Carefully swing in circles with tip of probe outward to force bubbles toward the top of the probe. Alternatively, probe may need replacement.
Primary Control Unit not starting up fully Partial or fully dead screen. Failure to fully boot up the PCU. Weak connection at the power supply due to corrosion and possibly overheating if ran for long periods. Check all connections in the PCU, especially to and from the power supply, for blackened/burnt wires or corrosion. Grind away anything that may impede a good connection.
Quick draining of connected air tanks Air tanks drain much faster than expected by calculation Leak in Mass flow controller. Open up the mass flow controller and identify the point of leakage. Spraying with soap is an option but care for electrical connections should be taken.
Improper pH control The pump module is operating but pH is not adeqautely adjusting A clog in the buffer line. This is common for thin tubing where salting out of any pH adjustment solution could occur. Try and break leak with tubing, cut leak out of tube and rejoin tubing together, or replace tubing.
