Product Description
Relay Time Delay 1.5 Sec.
Frequently Asked Questions
Q: What does the 1.5 second time delay on part CR 120104 do?
A: This relay delays signal activation by 1.5 seconds. On Crown and similar electric lift trucks, it prevents nuisance switching and protects control circuits from electrical spikes during startup or load transitions. The delay allows the vehicles electrical system to stabilize before engaging functions like hydraulics or motor circuits.
Q: Which Crown models use the CR 120104 relay?
A: This relay is commonly used in Crown Wave models and other Crown electric lift trucks manufactured between 2010 and 2018. Verify your specific model year and electrical schematic before ordering, as multiple versions exist. Cross-check your vehicles relay socket specifications to confirm fit.
Q: Can I replace CR 120104 with a different time delay relay?
A: No. The 1.5 second delay is calibrated for your specific vehicle control logic. Substituting a different time delay can cause erratic hydraulic response, poor acceleration, or failure to engage lift functions. Always use the OEM-specified delay timing.
Q: How do I diagnose if the CR 120104 relay is faulty?
A: Symptoms include delayed response to lift commands (longer than 1.5 seconds), intermittent function loss, or complete loss of hydraulic response after power-up. If your vehicle takes 3+ seconds to respond to controls or hydraulics do not engage at all, the relay may be failing. Visual inspection may reveal burnt contacts or corrosion.
Q: What is the lifespan of the CR 120104 relay under normal operation?
A: Under typical warehouse duty cycles (8-10 hours daily), this relay lasts 3 to 5 years. Heavy-duty continuous use or frequent power cycling reduces lifespan. Once replacement is needed, the part typically costs between 80 and 150 dollars depending on your supplier.
