Why is my Gardner Denver Controller showing a discharge over pressure?
A discharge over pressure error on your Gardner Denver Controller can be due to several reasons: * Operating pressure exceeded at 1.5 bar / 21 psi. * Pressure losses in the system are too high, which needs correction. * Nominal line pressure values are too high, so check remote-load / idle switching points. * External pressure demand is too high. * The suction regulator may not be closing. * The pressure sensor B1 or B2 could be defective, causing an incorrect display. In this case, check and replace if necessary.
How to fix high motor temperature M1 on Gardner Denver Controller?
A high motor temperature (M1) on your Gardner Denver Controller can occur for several reasons. It may be due to the drive motor being started too often, so limit the number of starts and stops. Insufficient cooling of the drive motor could also be a cause, so check the cooling air supply and improve it if necessary. Other potential causes include current draw being too high, a defective power supply, or a defective drive motor. Check the drive motor and replace if needed.
What causes a power supply failure on a Gardner Denver GD PILOT TS Controller and how to fix it?
A power supply failure on your Gardner Denver Controller can stem from several causes, including a power failure, voltage drop, damaged cables or wiring, or loose terminals. Check the cables and wiring, repairing them if needed. Also, check all connection terminals and plugs for secure seating and tighten if necessary.
What to do if my Gardner Denver GD PILOT TS Controller is showing a cooling error?
If your Gardner Denver Controller shows a cooling error on air-cooled systems, check the following: 1. Fan motor circuit breaker tripped: Check it. 2. Resistances too high in the supply / exhaust air channels: Check, and install additional fans if necessary. 3. Circuit breaker for the fan motor is set incorrectly: Set to 110% of the nominal fan current. 4. Fan motor is defective: Check, replace if necessary.
What does it mean if my Gardner Denver Controller is showing a low oil pressure warning?
If your Gardner Denver Controller is showing a low oil pressure warning, it indicates that the oil pressure is too low or absent.
What does it mean when my Gardner Denver Controller displays Fault VSD F064?
Fault VSD F064 on your Gardner Denver Controller indicates an overload of the frequency converter. Check the differential pressure of the fine precipitator, the oil level, and the water content of the oil.
What does error E403 on my Gardner Denver GD PILOT TS Controller mean?
E403 on your Gardner Denver Controller means that the compressor outlet temperature has been exceeded.
What to do if my Gardner Denver GD PILOT TS Controller shows a hardware error?
If your Gardner Denver Controller displays a hardware error, it indicates a hardware error at the controller. Replace the Delcos controller.
What should I do if my Gardner Denver GD PILOT TS reports an issue with discharge temperature sensor R2?
If your Gardner Denver Controller reports an issue with discharge temperature sensor R2, it may be due to a defective compressor outlet temperature sensor, a general pressure or temperature sensor defect, or faulty sensor wiring. Check and replace the sensor wiring if necessary. Also, check the pressure sensor and/or temperature sensor and replace if necessary.
