RS-500 5K Walk-In Cooler Door Installation and Operation Manual
Section 3.8.3: Deceleration Range
The Deceleration Range is the rate at which the door slows down as it approaches the Open Limit or the Closed Limit. The Smart
Controller sets the minimum Deceleration Range automatically based on the Open Speed and Close Speed (see Section 3.8.2). The
user can increase the time it takes for the door to decelerate by increasing program parameter P3 from the default value of 0 (see
Section 3.8.1). However, this should be done only if the door has problems stopping at the set limits, which can occur over time on
a large door.
Section 3.8.4: Open and Closed Limits
These limits are used to determine when the door is fully open and fully closed. They can be adjusted as follows:
1. Press and hold the Mode button for five seconds. "P1" (Close Time Delay) will be shown on the Display Indicator.
2. Press the Mode button continuously until "PS1" (Change Program Limits) is shown on the Display Indicator.
3. Press the Up arrow button until the Display Indicator shows "Yes".
4. Press the Mode button again. "PS2" (Set Open Limit) will be displayed.
5. The door will proceed to the Open Limit and then stop. Once the door stops, adjust the Open Limit using the Up and Down
arrow buttons.
6. Press the Mode button again. "PS3" (Set Closed Limit) will be displayed.
7. The door will proceed to the Closed Limit and then stop. Once the door stops, adjust the Closed Limit using the Up and Down
arrow buttons.
8. Press the Mode button again. The Smart Controller will exit Program Mode and will resume displaying the Actual Position.
Section 3.9: Jog Mode
Jog Mode allows the operator to manually control the position of the door. To engage Jog Mode, press and hold the Up and Down
arrow buttons simultaneously for five seconds. The Display Indicator will read "JOG".
While Jog Mode is active, the door can be opened and closed using the Up and Down arrow buttons. Because the door is not
affected by the home sensor or the safety beam during Jog Mode, the operator must carefully watch the door's movement as it
nears the fully open and fully closed positions to prevent it from overrunning.
To disengage Jog Mode, press and hold the Up and Down arrow buttons simultaneously for five seconds. The Smart Controller
will return to normal operation. Upon returning to normal operation, the Smart Controller will not know the exact position the
door was in when Jog Mode was disengaged; the Display Indicator will thus show a series of three horizontal bars. Upon the next
command the door will slowly proceed to the fully open position to reset the Smart Controller's memory; the door will always
follow this procedure upon exiting Jog Mode.
