RS-500 5K Walk-In Cooler Door Installation and Operation Manual
Service Reminder
When the Smart Controller has exceeded the selected Service Cycle Limit, the Service Cycles LED begins flashing to indicate
service is required (see Section 3.8.1).
Door Obstruction
If an object (
e.g.
a person or a forklift) interrupts the infrared safety beam, contacts the leading edge switch, or trips the auxiliary
safety sensor, the door will stop descending, then proceed to the fully open position if configured to do so. The Door Obstruction
LED (a red dot at the bottom-right corner of the Display Indicator) will be illuminated until the obstruction is cleared.
Jog Mode
This is shown when the Smart Controller is in Jog Mode (see Section 3.9).
Assumed Position
When the Smart Controller is powered on, after the software version and model number disappear, the Display Indicator
alternates between the Actual Position reading and the Unknown Position notification until the door is activated. This indicates
the Smart Controller has assumed the current position of the door. When the door is activated, the door proceeds to the open
limit position at full speed. It then proceeds to the home sensor to verify the position reading, after which it returns to the open
limit position. This operation verifies the door was not manually adjusted while disconnected from power.
