3.3.2 Limit 
Adjustment for 9220, 9230 Operators 
The 9220 and 9230 operators utilize a pair of switches at the open and close positions.  The first 
switch is the slow-down switch and the second switch is the limit switch.  The slow-down switch is 
adjustable so that you can increase or decrease when the slow-down is initiated.  For example, on 
heavy gates it is desirable to increase the slow-down distance to provide the operator more time to 
slow-down and stop the gate. 
 
1. 
Turn power off. 
2. 
Adjust the limit nuts as described in 3.3.1. 
3. 
Loosen the nut that fastens the slow-down switch bracket to the partial open limit 
switch bracket.  This will allow the slow-down switch assembly to move up or down 
approximately 3/4 inch.  DO NOT remove the slow-down switch assembly 
completely from the bracket it is attached to and then re-attach it in the larger 
slot on the bracket in an attempt to gain further adjustment.  This will only 
cause mechanical damage to the switch assembly when the operator is 
activated.
 
4. 
To increase the slow-down distance, move the slow-down switch away from the limit 
switch.  To decrease the slow-down distance, move the slow-down switch closer to 
the limit switch.
