e1 TROUBLESHOOTING STEPS:

​

Safety Note: Before any component is electrically disconnected in the unit, shut off main power. Inverter board DC bus voltage can take up to 15 min to discharge.

​

Caution: Do not plug or unplug components while electrical power is present, this can damage the equipment and control boards.

​

Step 1: Check the Pressure Transducer

• Examine the pressure transducer for any visible signs of damage, such as cracks, leaks, or physical deformities.

• Ensure that the pressure transducer is securely connected to the system and that its wiring is intact. Look for any loose or disconnected wires.

• Measure the voltage or resistance output of the pressure transducer using appropriate testing equipment. Compare the readings to the manufacturer's specifications to determine if the transducer is within the expected range.

• If the pressure transducer is providing inaccurate readings or is outside the specified range, consider replacing it with a new transducer that meets the system requirements.

• Check for any obstructions or blockages in the pressure transducer's tubing or connection points that may affect its performance.
