How to Replace Honeywell Modutrol Motors with Econex AR2 Series Motors
A Comprehensive Guide for Burner and Combustion Engineers
When dealing with the replacement of Honeywell Modutrol motors, selecting the appropriate Econex AR2 series motor is crucial. This guide is designed to help burner and combustion engineers seamlessly transition to using Econex motors, ensuring compatibility and optimal performance.
Understanding the Compatibility
The Econex AR2 series motors are designed as direct physical replacements for Honeywell Modutrol motors. They share identical mounting holes, drive shaft sizes, and locations, making the installation process straightforward without requiring any physical modifications. However, several considerations must be addressed regarding the electrical supply and control signals.
Electrical Supply Considerations
All Honeywell Modutrol motors operate on a 24V supply. This voltage is either generated by a transformer located within the Honeywell motor or from a transformer in the burner control panel. Identifying the source of the 24V supply is the first step in selecting the correct Econex replacement motor.
Electrical Supply Considerations
All Honeywell Modutrol motors operate on a 24V supply. This voltage is either generated by a transformer located within the Honeywell motor or from a transformer in the burner control panel. Identifying the source of the 24V supply is the first step in selecting the correct Econex replacement motor.
24V Supply from Burner Control Panel:
If the 24V supply comes from the burner control panel and remains unchanged, the replacement motor should be an Econex AR2A series motor.
Model to select: AR2A2002-???
24V Supply from Transformer in Motor:
If the 24V supply is from a transformer mounted within the Honeywell motor itself (supplied with either 110V or 230V from the burner control panel), the existing 24V transformer must be removed. The appropriate Econex motor, which includes a built-in 24V transformer, should be selected based on the supply voltage:
- For 110V supply: AR2B/A2002-???
- For 230V supply: AR2C/A2002-???
Control Signal Considerations
The correct Econex motor also depends on the control signal, which could be either 0-10V or 4-20mA. It is important to establish the existing control signal to select the precise motor model.
0-10V Control Signal:
- For 24V supply: AR2A2002-SE4
- For 110V supply: AR2B/A2002-SE4
- For 230V supply: AR2C/A2002-SE4
4-20mA Control Signal:
- For 24V supply: AR2A2002-SE5
- For 110V supply: AR2B/A2002-SE5
- For 230V supply: AR2C/A2002-SE5
Unknown Control Signal:
If the control signal is unknown or cannot be identified, the "SE2" version of the motor is a versatile option that accepts both 0-10V and 4-20mA signals.
Recommended versatile model: AR2A2002-SE2 (24V), AR2B/A2002-SE2 (110V), AR2C/A2002-SE2 (230V)
