Carrier inverter ac p4 error

One of the most neglected electrical products used in industrial automation is the humble inverter. Rarely is a piece of equipment so straightforward and reliable that process engineers forget it exists. Here, Jonathan Wilkins, the marketing manager of obsolete and spare industrial automation parts supplier, European Automation, explains why even the most resilient components sometimes fail and what to do when this happens.

Although, I suppose when you think about it, he only has three really, if you include his decision in to become known by a symbol instead of a word. Power inverters can be completely electronic or combine mechanical effects with electronic circuitry.

Since inverters convert DC electricity from batteries, solar panels or fuel cells into AC electricity, the applications they can be used in are extremely diverse.

Electric motors are used everywhere in industry, including in the food and beverage sector for anything from fans, ventilators or conveyor belts to pumps and refrigeration vans. The most common cause of failure or malfunctioning for inverters is an improper installation, often a combination of not following the user manual recommendation and selecting inappropriate cable type, gauges or in line fuses.

Capacitor wear The first reason for inverter failure is electro-mechanical wear on capacitors. Inverters rely on capacitors to provide a smooth power output at varying levels of current; however electrolytic capacitors have a limited lifespan and age faster than dry components. This in itself can be a cause of inverter failure.

Capacitors are also extremely temperature sensitive. Temperatures over the stated operating temperature, often caused by high current, can reduce the life of the component. However, as the electrolytes evaporate faster at higher temperatures, capacitor life increases when they are run at lower than operating temperature.

Happily, keeping a consistent maintenance regime and regularly replacing capacitors avoids most problems caused by wear and tear. Overuse We mentioned how sometimes process managers might forget about inverters. This happens more often than you think.

Using inverters beyond their operating limit, either by choice or due to oversight or lack of knowledge, can contribute to inverter bridge failure. Using any component at a rating higher than its operating limit will decrease its lifespan and lead to failure, so avoiding this issue simply comes down to checking that all inverters are being run correctly. Over- and under-voltage The next two issues that can cause inverter failure are over-current and over-voltage. If either current or voltage increases to a level that the inverter is not rated for, it can cause damage to components in the device, most frequently the inverter bridge.

Often this damage will be caused by the excess heat generated by the spike in voltage or current. Over-current can be avoided with fuses or circuit breakers, but avoiding over-voltage can be tricky.

Sometimes voltage spikes are man-made, but they can also be caused by lightning or solar flares, which are difficult to avoid if, like us, you live on planet Earth. Ultrasonic vibrations The final problem on the list is one that contributes to the mechanical stress placed on an inverter. Ultrasonic vibrations originating in the cores of inductive components cause friction, adding to the unwanted heat generated by the device and further damaging components in the inverter.

With time, electrical connections tend to loosen or corrode. If the inverter is still functional, a maintenance manager might be tempted to simply ignore these signs of wear and tear.

Furthermore, the cleaning process has to be performed correctly, or it might end up doing more damage than good. Ideally, a wire brush and grease dissolvent agent should be used. After cleaning and maintenance is complete, a protective sealant must also be used on all battery terminals. When deciding which protective coating to use, avoid grease-based ones, because they tend to attract contaminants like dust, which leads to an increased decay of the connections, while also hiding the degradation from further visual inspections.

Although correct installation and maintenance can significantly prolong the lifespan of inverters, when failure does happen, there are a few routes you can take.

Especially for older or obsolete models, it might be worth considering the purchase of a refurbished part. About European Automation: European Automation stocks and sells new, used, refurbished and obsolete industrial automation spares.

Mini split air handler was displaying a P4 Error Code. When I hooked up my gauges the standing pressure was between psi for a A system. Inside Air temp must have been about 80 degrees. Compressor kept short cycling. Any idea what it could be? I thought my standing pressure seemed high.

Noticed the compressor would cut out at psi also. Contact Tech Support! I know Fujitsu will do that if min lineset length too short or too long. Low refrigerant charge will also short cyling. Went back today and same symptoms persisted. Standing pressure of cutting off at Tech support said it could be the board but I don't think it's that.

The pressures don't look right to me. Upon releasing the refrigerant after pulling a vacuum I opened the suction line first before opening the liquid line. Could this have been an issue? I recovered all the refrigerant and charged it again. Also took amps on the compressor and it ramps up above the water 12amps to around 17 amps before it cuts off. Sent from my iPhone using Tapatalk.
