What is the function of the Interface Board Test Mode?

The function of the Interface Board Test Mode is to enable the technician to energize and de-energize individual control devices without requiring the engine to be running. This mode is particularly valuable during diagnostic procedures as it allows detailed testing and verification of specific components within the system without the complexities that arise from engine operation. By isolating control devices, technicians can assess their functionality, identify faults, and troubleshoot issues more effectively.

Utilizing this mode aids in pinpointing which components are operational or malfunctioning by allowing for controlled testing scenarios. This approach is not only efficient but also crucial for ensuring accurate diagnostics and effective maintenance of the refrigeration units.
