Frequently Asked Questions
Q: What is the CR 118278-1 encoder and what does it do?
A: The CR 118278-1 is a revised encoder assembly for Crown electric lift trucks. It provides real-time motor speed and position feedback to the trucks control circuit, enabling smooth acceleration, precise speed control, and accurate load handling. This is a critical component for drive system functionality.
Q: How do I know if my truck needs the CR 118278-1 versus the CR 118278-001?
A: Check your trucks control module part number and manufacturing date. The CR 118278-1 is the newer revision and is used on Crown trucks built in the 2010s onward. If your truck is older, you likely need the CR 118278-001. Contact your control module documentation or verify the encoder connector type on your existing unit.
Q: What connector type does the CR 118278-1 have?
A: The CR 118278-1 uses a sealed, weather-resistant connector designed for material handling environments. The connector pins are gold-plated to resist corrosion. Always inspect the connector and mating port before installation to ensure no debris or moisture contamination.
Q: Can the CR 118278-1 be used as a replacement for older encoder models?
A: Not all older encoders are interchangeable with the CR 118278-1. Encoder revisions are tied to control module compatibility. Installing an incorrect encoder revision may cause control system errors or failure to communicate with the drive circuit. Always match the encoder part number to your specific control module.
Q: What are the symptoms of a failing CR 118278-1 encoder?
A: Symptoms include erratic speed changes, truck does not reach full acceleration, loss of steering responsiveness, or the control system displays a sensor fault code. The truck may limp home at reduced speed or shut down entirely. The encoder is sealed and cannot be repaired, so replacement is the only solution.
