RS-500 5K Walk-In Cooler Door Installation and Operation Manual
Section 5.2: P12 Input Status Indicators
This program parameter is used to service and troubleshoot the door. The inputs are represented by LED segments on the Display
Indicator. If an LED segment is on, the corresponding switch is closed. If the segment is off, the switch is open.
Important P12 status indicators are as follows:
1. For the door to close, the Primary Safety and Leading Edge segments must be off.
2. If the Stop Switch segment is on, the door will not operate.
3. If the Open Switch segment is on, the door will not close.
4. The KB Status segment is on when the variable-frequency drive is charged; it is off when the drive is powered down.
5. The CMS Status segment is on when the Condensation Management System is running; it is off when the CMS is not running.
