Frequently Asked Questions (FAQ)
Q1: What is the input resistance?
A: Approximately 6.7 kΩ. Suitable for standard voltage sensing inputs.
Q2: Can I use this for paralleling?
A: No. The easYgen-1500 features target non-paralleling applications only.
Q3: How do alarm classes work?
A: Class A and B stay as set. Classes C,D,E,F convert to Class B alarms automatically.
Q4: What happens during mains failure while starting?
A: The unit keeps running. It stops only after mains return and settling time expires.
Q5: Does this support remote start?
A: Yes. Remote-start capability is built in.
Q6: Experience-based tip: What fails most often?
A: Most field issues come from poor CAN termination. Always add a 120 ohm resistor at the last node.
Q7: Experience-based tip: How to avoid display lag?
A: Use a clean 12-24V DC supply. Avoid sharing power with large contactors.
Q8: Purchasing guide – New or refurbished?
A: Choose new surplus for critical sites. Refurbished works for testing or backup units. AX Control INC offers both.
Q9: Purchasing guide – Which accessories are needed?
A: Buy the IKD 1 module for more I/O. Add Easylite-100 for remote NFPA annunciation.
Q10: Can I use this with Modicon Quantum?
A: Yes. Use Modbus RTU to connect. See Modicon Quantum products for compatible PLCs.

Ordering & Selection Guide
– Need 1 or 2 breaker operation? Confirm before ordering. – Need remote annunciation? Add Easylite-100. – Need extra I/O? Select Woodward IKD 1 module. – Mobile application? Choose 12V DC power setup. – Emergency standby? Ensure 24V DC supply with backup.
Popular selection tip: For NFPA compliance, always pair with Easylite-100 panel. For engine ECU control, verify J1939 support first.
