Frequently Asked Questions
Q: What is the RA 1-120-112/004 potentiometer used for?
A: The RA 1-120-112/004 is a potentiometer used in Raymond electric pallet truck speed control systems. It is a variable resistor that translates operator joystick or pendant lever position into electrical signals for motor speed management.
Q: What does the slash notation mean in the SKU RA 1-120-112/004?
A: The /004 suffix indicates a specific revision or configuration variant of the RA 1-120-112 potentiometer. This notation identifies the exact assembly version required for your equipment. Do not substitute different revision numbers, as performance may be affected.
Q: Which Raymond models use the RA 1-120-112/004?
A: The RA 1-120-112/004 is used on specific Raymond electric pallet truck models. Check your equipment manual or OEM documentation to confirm this potentiometer is correct for your truck. Installing the wrong model potentiometer will affect speed control performance.
Q: How do I diagnose a failing RA 1-120-112/004?
A: Symptoms of potentiometer failure include erratic speed response, inability to creep slowly, jumping to full speed unexpectedly, or no motor response to control input. Test continuity with a multimeter across the potentiometer terminals. If resistance does not change smoothly with lever movement, replacement is required.
Q: Is the RA 1-120-112/004 a sealed part?
A: Yes. The RA 1-120-112/004 is a sealed potentiometer and cannot be repaired, adjusted, or cleaned internally. Water intrusion, corrosion, or contact wear requires complete unit replacement with a new OEM potentiometer to restore control accuracy.
