7.04.001 High Compressor Oil Temperature - Electric Drive - (Troubles Shooting Guide)

This Policy is Under Development. If questions please contact Area Manger.

Purpose

The purpose of this trouble-shooting guide is to assist you in diagnosing a High Compressor Oil Temperature fault.

Procedure

This procedure applies to all units that are currently in service in the field, at a repair shop, and in storage yards.

Before any work is performed a JSA must be completed according to Flogistix procedure along with any customer requirements before any work is started.

Help guide to trouble shooting a High Compressor Oil Temperature fault.

Diagnosing High Compressor Oil Temperature

Are you having high compressor oil temperature faults? Follow this help guide to resolve your issue.

Step 1: Start by checking the thermal couple. The thermal couple is used to read the temperature of the oil before it enters the compressor, loose terminations or faulty thermal couples can cause a false reading. Verify the temperature by using a temperature reading gun to know the estimated temperature that it should be reading. Verify terminations are tight and nothing is loose on the inside.

Did this correct your issue? If not continue to step two.

Step 2: Check cooling fan operation. Verify the cooling fan is turning on at the desired temperature. To check this, you can login as mechanic and continue to the settings page. Locate the cooling fan control page and change the desired temperature for the fan to turn on lower than the actual reading at the time. Give it a few seconds to get the signal and verify its operation. If the fan is not working, there are a few things it could be. Check the command wire on TB2, #3. Verify there is a -24 reading when the fan is being commanded to run. If there is a +24 instead of -24 the PLC will need replacement. If you are getting the correct -24 supply to that terminal the possibility that there are further issues inside the VFD cabinet rises. You will need an electrician to further diagnose into the cabinet. Have an electrician check wiring, fuses, command relays, etc.

Did this correct your issue? If not continue to step three.

Step 3: Check thermostat operation. All packages should be using a 230-degree thermostat. This means once the compressor oil temperature rises above the 230 degrees the thermostat will open allowing oil flow to through the cooler. By allowing the temperature to rise to operating standards you should be able to feel the heat on the piping change from cool to hot. The supply line to the thermostat will always be hot, the supply line to the cooler will change throughout operation. If supply line to the cooler does not heat up after reaching 230 degrees that means that the thermostat is not opening allowing the oil to cool down before continuing through the system. Thermostat will need replacement if the above applies.

Did this correct your issue? If not, continue to step 4.

Step 4: Continue diagnosing by checking for a restricted oil cooler (inside or outside). Using a temperature gun, you can monitor the temperature and tell whether the gas is going through the cooler and cooling or having issues being clogged. If cooler is clogged a flush may be necessary.

If issues continue after using this diagnostic sheet, contact your area lead for further instruction.

Responsibilities

Management - Management is responsible for implementing, supporting, and enforcing the requirements of this procedure to their respective locations/area.

Scope

Hazards

Employees should be aware that units could contain flammable and toxic gasses. Potential for the possible hazards of gas ignition or fire, hot surfaces & fluids, rotating equipment. Risk of possible concentration of H2S. Hazardous gases could be in the units pressure vessels, cooler, or associated piping and risk of inhalation of hazardous gas fumes. Environmental spill of compressor oil and possible production fluids

Safety

All Personal Protective Equipment (PPE) for normal Field Mechanical duties apply for this procedure. Four Gas Monitor, which is outlined in the Flogistix EHSS Manual, PPE Section 8, Procedure 8.3 This procedure applies to all units in service in the field, at a service shop, or in any storage yard.
