RS-500 5K Walk-In Cooler Door Installation and Operation Manual
Section 5.4: Smart Controller/Smart Switch Error Indicators
The error indicator LEDs to the left of the Open and Close buttons on the Smart Controller and Smart Switch are used to
troubleshoot door issues, display the door's operational status, and warn personnel of door movement.
1. If an LED is solid, the corresponding sensor has encountered an error.
2. If all eight LEDs fade together, the door is in a timed open cycle and will eventually begin a close cycle.
3. If all eight LEDs flash together, the door is either moving or about to move.
