I have a customer that is using a Kouwa Mod# KMU-150-M-16-B S/N 181776 oil cooler. Can you tell me what pressures to expect and how much 407C is supposed to be in the unit? We just replaced a stuck compressor and my suction pressure is at 0Psi.

The above Model is on a Machine where I continually get an \"E8\" Error for Thermal Relay Overload. The Compressor will run for no more than 1 minute. Amps or Watts run high.

The Compressor will run for no more than 1 minute. Amps or Watts run high. Seems like an internal failure on Compressor. Any other thoughts before I replace Compressor? Condenser Coil is clean, great airflow. Nothing noticeable at Liquid Filter screen before Cap Tube.Also on this Unit it says Refrigerant is R407C. Any ideas on how much Refrigerant is in System in pounds?Any Tech info on this unit in regards to the Refrigeration cycle would be great.Thank you,Andrew Maass

The problem is that I am getting three alarms. The chiller unit in giving an E-9 alarm ( Oil pressure (flow) is lowered.) Consequently, that is generating two alarms on the masak machine side. 206 Spindle Lube chiller malfunction. And also, 392 Thermal Displacement offset Error. I\'m sure both of the masak alarms are related to the chiller alarm. My Question is, what would cause the chiller unit to generate the E9 alarm? Plugged suction strainer? Pump going bad? Motor? The unit is only about three years old. Any advise would be greatly appreciated. P.S. The problem is intermitant. And can usually be cleared by powering off unit and machine, and powering back on.

Ambient pressure is around 140psi at 75 degrees. Unit will run for about 3 -5 minutes and throw the code. Current to the compressor is about 3.6 amps. Is this a good value? On page 8 of the check out procedure the term \"thermal setting value\" for current is listed in the E8 alarm procedure. What is the normal thermal setting value for current draw? What are the normal operating pressures and current load for this unit when running properly? Any ideas on what needs to be replaced?

The CM motor starter 4th from left was dirty with carbon. We changed it out. Still trips. We ohm'ed out the motor. Seemed good. Thinking what the motor is spinning had frozen up but the e stop won't go away and the chiller never starts. I get the 4 dashes at boot up and I can push the parameter button to see A200. Nothing else shows on the display, no alarms.

I am unsure why this is happening, as the three circulation pumps and the compressor are not activating. Additionally, the CNC lathe which we are using the unit on, does not trigger an alarm indicating that the unit is not cooling the oil. Can you assist us in understanding the problem and finding a solution? Thank you in advance.
